　　Chaoyang, Beijing — —

　　Shangchao sales and stocking are busy.

　　On January 14, I walked into the sweet water garden store of Jingkelong Supermarket in Chaoyang District, Beijing, and the strong flavor of the year came on me. On the glass curtain wall, huge window stickers focus on the theme of the Year of the Rabbit, and red lanterns are hung high on both sides of the door. On the shelves in the supermarket, "candied melon sticks", peanuts and melon seeds are piled up into hills, and Daoxiang Village dim sum box, old Beijing roast duck gift box and New Year’s Eve gift box are renewed in turn.

　　Many kinds of fish are very popular in the fresh aquatic products area. "From the opening of the door in the morning to the present, the hairtail on the shelf is sold short, and it can sell about 400 kilograms every day." Chen Song, the clerk in charge of selling hairtail, said while busy.

　　Mr. Liu, a citizen who came to buy the new year’s goods, carefully selected the dried fruits, and soon the harvest was full: "This Spring Festival, the children will come home, so they came to buy all kinds of dried fruits and leisure snacks early. The supermarket has a complete range of goods and everything they want to buy."

　　"This is only the beginning of the sales of new year’s goods, and it will usher in a peak period in the next few days." Guo Dongnian, manager of Jingkelong Sweet Water Garden Store, said, "In the past, everyone’s shopping carts were piled with rice flour, grain and oil, as well as easy-to-store dishes such as Chinese cabbage, potatoes and onions; Now, most of them are leafy vegetables, fresh fish, fresh shrimp and fresh fruit, many of which are high-net-worth goods. "

　　In response to customers’ diversified and quality needs, supermarkets have also opened pre-sale channels while actively stocking up. Customers can order light snow strawberries, Maoshanwang durian, cherries, red pine mushrooms and other commodities, and receive them at home on time, which is both fresh and convenient.

　　There should be a new atmosphere in the new year. Looking forward to the new year, Guo Dongnian told reporters: "In 2023, the store will usher in an overall transformation and upgrading, from the ground and ceiling to the shelves and promotional activities. We are full of confidence in welcoming the Spring Festival. "

　　Chengdu, Sichuan — —

　　Characteristic business circle is full of vitality

　　At noon on January 17, the reporter came to a commercial complex in Jiaozi Financial Business Circle, Chengdu High-tech Zone, Sichuan Province, and saw an endless stream of citizens and tourists, talking and laughing in and out of the mall, and a scene of jubilation.

　　"I will go back to my hometown in Shaanxi tomorrow, and I will come shopping as soon as the mall opens today." Mr. Wu, who is on a business trip to Chengdu, holds the special ingredients such as the bottom of a wok and beef in one hand and a panda doll souvenir in the other. He smiled and told the reporter, "If you eat, you can send your relatives, and the panda doll will be given to your daughter."

　　Walking into the shopping mall, the annual flavor is full, lanterns, zodiac rabbits and other Chinese New Year elements can be seen everywhere, and many counters put up posters with full discounts and points redemption in eye-catching positions. "In the past few days, we have specially extended the business hours and increased the security to ensure that citizens and tourists have a good time in shopping malls and buy with confidence." The person in charge of the mall told the reporter.

　　The Spring Festival is approaching, and the warming trend of Chengdu consumer market is obviously enhanced. As a large-scale commercial complex in Jiaozi Financial Business Circle, Chengdu Youfang Shopping Center will continue to launch exhibitions such as trend art exhibitions, as well as promotional activities such as redemption of points and over-value discounts during the Spring Festival holiday, creating a rich consumption scene that integrates eating, drinking and shopping, so that citizens and tourists can experience the traditional taste of the year and multiple pleasures. The Mofang Shopping Center adjacent to Youfang Shopping Center will also launch special packages during the Spring Festival holiday to open a new experience of food fashion consumption.

　　The data shows that in the fourth quarter of last year, the daily average number of visitors to Chengdu Jiaozi Financial Business Circle reached 148,000, an increase of 47.7% compared with the third quarter, and it has maintained a steady upward trend. During the New Year’s Day holiday this year, the retail and catering enterprises under key monitoring in Sichuan Province achieved a cumulative sales of 2.26 billion yuan, up 6.7% year-on-year. In order to meet the diversified consumption needs of citizens to a greater extent, help market players gather popularity and increase confidence, Chengdu High-tech Zone also launched the first Jiaozi International Consumer Festival and other theme activities to bring more fresh and diverse high-quality consumption experiences to citizens and continuously stimulate consumption potential.

　　Guangzhou, Guangdong — —

　　Restaurant reservations are booming.

　　On January 15th, Huifu Food Flower Street in Guangzhou, Guangdong Province, was bustling and bustling in the twilight. Citizens enjoy flowers for dinner, and their faces are filled with the happiness of the Spring Festival.

　　"I specially brought my family here today, ate an authentic Cantonese food, and bought some flowers to decorate the house." Mr. Gao, a family of six, booked a table in advance before the rush hour and sat in the almost full Guangzhou restaurant.

　　"The recent passenger flow has increased by nearly 20% compared with the same period of last year." The person in charge of Yuehua Store of Guangzhou Restaurant said that the demand for dining was very strong during this period. The private rooms and the first round hall of the store during the Spring Festival holiday were basically fully booked, and more than half of the second round had been booked.

　　Huifu Food Flower Street is one of the first batch of Cantonese food streets in Guangdong Province, and it is also an important part of Guangzhou Beijing Road National Demonstration Pedestrian Street, with a total length of nearly 400 meters and more than 120 restaurants.

　　It is understood that the recent turnover rate of Guangzhou Restaurant, Big Pigeon Rice and other Cantonese food brand stores in Huifu Food Flower Street has exceeded 6%, and the booking rate of small and medium-sized private rooms such as Lucky House and Yuepin House is close to full, and there are long queues at the gates of Zhuangchen Food Store, Big Head Shrimp and Wentong Ice Room. During the Spring Festival holiday this year, many food and beverage outlets in Guangzhou will carry out profit promotion activities, offer multiple discounts for new year products such as potted vegetables and rice cakes, and develop a number of special dishes for the Spring Festival.

On January 15, the total passenger flow on Beijing Road will exceed 600,000, an increase of 7% over the same period of last year. " The person in charge of the Management Committee of Beijing Road Cultural Core Area in Guangzhou said that since the New Year’s Eve, Beijing Road Pedestrian Street has held the "Welcome New Year to Buy New Year’s Goods" to promote consumption, which will continue to attract passengers and stimulate consumption.

Liu Datian, an "imperial doctor", prescribed a prescription on the spot.

Red Star News reported on December 3 that a month ago, Liu Datian, a 70-year-old man who had been wandering outside for many years, suddenly became a "magic doctor". Every morning at 2: 00 or 3: 00, people queue up to see him, working 12 hours a day, and besides having three meals and sleeping, they are all prescribing prescriptions, and the consultation fee has also risen from 5 yuan to 100 yuan.

Among the "stories" circulating in the local area, Liu Datian once cured a child who was judged by the hospital to be "short of time" and also cured a hemiplegic patient to be "able to go to the fields to catch up". However, after investigation by reporters, it was found that the first story was unfounded and the second story was also false.

After verification by the local health law enforcement supervision brigade, Liu Datian has no medical qualification, and his medical place has been banned.

The tramp turned into a "magic doctor"

On November 29, the reporter went to Tianbao Village, Nanyue Town, Dachuan District. In a yard, there were 10 people warming themselves around the brazier in the courtyard dam. Under the eaves of blue bricks, there were a group of men and women around an old man with a white beard.

The old man, wearing a green coat, a washcloth on his left shoulder and a snow hat, is burying his head in writing prescriptions one by one, asking people who come to write prescriptions from time to time, "What other diseases are there?" "He is very slow in writing prescriptions, and it takes a big outline for 20 minutes." Ms. Jiang, in her 50 s, said.

At the scene, the reporter learned that the old man who prescribed the prescription is the legendary "imperial doctor", whose real name is Liu Datian, who is 74 years old.

Liu Datian writes prescriptions in his hometown, and about 30 people come to him to write prescriptions every day. My nephew Liu Sheng (a pseudonym) stands in line at the scene to keep order.

"30 a day, I have already got December 3, and I didn’t get the number on the 3 rd to get the number on the 4 th." Liu Sheng said. Because many people came to write prescriptions, Liu Sheng came to keep order and figure out how to queue up with numbers.

On the same day, the number of people who came to see Liu Datian increased one after another. At noon, Liu Datian ate a box lunch and began to "work" again until 7 o’clock in the evening. The reporter observed that Liu Datian is different from other doctors in seeing a doctor. He doesn’t care if the other person is a patient. No matter what the disease is, he can prescribe medicine as long as he can tell the symptoms.

The reporter found several prescriptions he prescribed and made a simple comparison. The prescriptions were all one or two (traditional old-fashioned prescription measurement units), and a prescription contained at least 10 kinds of Chinese medicines and at most 25 kinds of Chinese medicines, and some Chinese medicines were repeated in the prescriptions.

Wu Zejun, a villager in Liu Datian’s village group, said that Liu Datian used to be a "doctor" and it is more accurate to define him as a "quack doctor". Liu Datian had been working as a "barefoot doctor" in Pingtan Township and Anji Township in Dachuan District. His family was not bad. When he was young, his family changed suddenly, and his wife left, leaving only him and his younger brother to live. Later, Liu Datian wandered outside for about 50 years. "Because my brother still beats him from time to time, Liu Datian wanders outside and rarely goes home." Wu Zejun said.

Guo Tingyuan, the old secretary of the village, said that Liu Datian had been wandering around Nanyue Town and became a famous tramp in Nanyue Town, looking for leftovers to take home for his younger brother.

Liu Datian usually sleeps in a brick factory when he doesn’t go home. If he really can’t find food, he will also ask others for "one or two yuan" and don’t want more money.

As for Liu Datian’s prescription, everyone in Nanyue Town knows that it took about a month to return to his hometown Tianbao Village in the last week.

On November 30th, a woman who lives in Nanyue Town came to write prescriptions. She told reporters that when Liu Datian, a "magic doctor", wrote prescriptions in the street, about 100 people lined up to ask him to write prescriptions every day, some at two or three o’clock in the morning. Liu Datian had almost no rest except for three meals a day and sleeping. "All of them were writing prescriptions (prescriptions)".

Resident Deng Shengbai introduced that Liu Datian went to sleep under the eaves of his home half a month ago. At that time, there were about 200 people who saw him every day, and their doors were packed. Some people came from Chengdu, Chongqing and Guang ‘an, and others came from Dazhou City and nearby towns and villages.

According to the residents around, Liu Datian practiced medicine in Deng Shengbai’s place for about a week, and people were full every day. Because he practiced medicine without a license, Nanyue Town Government and Dachuan District Health Law Enforcement Supervision Brigade banned his place of practice, and then Liu Datian returned to his hometown.

The consultation fee rose from 5 yuan to 100 yuan.

At 11 o’clock on the evening of the 29th, the reporter came to Liu Datian’s hometown. Three women were warming themselves in Liu Datian’s house, waiting for Liu Datian to get up and prescribe medicine.

"The two of us have been here several times, but we haven’t got a prescription. (29th) We didn’t have breakfast in the morning, lunch and dinner, just to make a prescription for a number." Zheng Fen (a pseudonym), a woman from Nanyue Town, said.

At 1 o’clock in the morning on the 30th, four women from Dazhou City rented a car to queue up. Two hours later, several people came to ask Liu Datian for a prescription. Liu Datian didn’t get up until after 5 o’clock in the morning.

After Liu Datian sat down, he had to pay for the prescription first. Four women from Dazhou gave it to 300 yuan. Liu Datian said, "400 yuan delayed my drowsiness, or I wouldn’t open it." Four women borrowed 100 yuan from an acquaintance at the scene, and Liu Datian wrote four lists, and then four women left by bus.

Zheng Fen told reporters that November 29th was a prescription for 50 yuan, but it rose to 100 yuan on November 30th. The reason for this price increase is uncertain. "200 yuan, 300 yuan and 20 yuan, 10 yuan behind us, which were given by rich people, can’t get it, and now the general price is 100 yuan."

Deng Shengbai told reporters that when Liu Datian saw a doctor and prescribed a prescription at his doorstep, 5 yuan gave a prescription at that time, and some gave it to 10 yuan. This charge is not fixed. If the rich give it to 100 yuan and 200 yuan, he will open it first, while others will wait in line if they give less money.

Liu Sheng, Liu Datian’s nephew, said: "There are still people from 500 yuan and 1000 yuan. He (Liu Datian) wants to accept it, and he will prescribe it first."

On December 3rd, the reporter went to Liu Datian’s home again, and 100 yuan wrote a prescription. First, he gave money, then registered, and finally he saw a doctor and wrote a prescription.

Liu Datian’s prescription fee record.

Reporter’s investigation: Both "stories" are rumors.

Why do so many people find a tramp "magic doctor" to prescribe medicine? A woman who saw a doctor at the scene said, "I heard that he cured a child who could not be cured in a big hospital." There is also a paralyzed patient who has been cured by him for more than 10 years. "

As a tramp, Liu Datian suddenly turned into a "imperial doctor", and these two stories are circulating in the streets of Nanyue Town and in the mouths of villagers:

One story is that there is a child in a town not far from Nanyue Town. After being treated in a big hospital in Chengdu, the conclusion is that the child’s time is running out. My family suddenly had a dream one night, dreaming that someone said that finding a vagrant and beggar to prescribe a prescription could cure the disease. After inquiring, I finally found Liu Datian and prescribed a prescription, and the child recovered after eating it. Another story is that a paralyzed patient took the medicine prescribed by Liu Datian and was able to go to the streets to catch the show.

Are the two seemingly absurd stories true?

The reporter inquired in many ways and did not find the specific home address and contact information of the child in the first story. Liu Sheng, Liu Datian’s nephew, also said that he didn’t know about it himself. He asked Liu Datian, but he didn’t know, and the other party didn’t leave any contact information.

Regarding the paralyzed patient who went to the streets after taking medicine, the reporter contacted Wu Moumou, the family member of this person. In Wu’s home, he took out his and his wife’s prescriptions.

Wu Moumou said that he got up early in the morning and went to the street to find Liu Datian to prescribe a prescription, and took the medicine home to his wife. "After you boil it out, drink a small bowl three times a day." Wu Moumou said. After taking the medicine, my wife seems to be in better spirits.

Wu Moumou introduced that his wife, Yang, did take a trip to the street. She left by herself. "On that day, she didn’t take medicine for cerebral thrombosis. After returning home, she was weak and bedridden again and was sent to the hospital for treatment."

Is it Liu Datian’s medicine that makes his wife walk in the fields again? Wu Moumou said that this is not the truth. "She can usually walk at home, but slowly." Wu Moumou said.

Patient: I don’t believe that he is an imperial doctor, but I have a try attitude.

The reporter found that the people who came to seek Liu Datian’s medical treatment were almost all people in their 50 s and 60 s.

Shao Yinyin (a pseudonym) from Dazhou City introduced that he didn’t believe that he was a "magic doctor". He just heard a friend say that Liu Datian was quite hot recently, and the medicine he prescribed was effective. He specially drove from Dazhou overnight to Nanyue Town to find him and prescribed a medicine, "Try it for a mentally ill son".

On December 3, Shao Yinyin called the reporter and said that she had seen a doctor. Liu Datian prescribed a medicine for treating stomach problems for her son. "The medicine was caught, so I dare not give it to my son."

On the same day, a couple who were still waiting for Liu Datian’s prescription introduced that his wife was suffering from tuberculosis and had not recovered for a long time. They came to ask Liu Datian for a prescription from Dazhou. The couple said that they also heard from others that the prescription was effective after eating. "Let’s try it on purpose, in case it works." As for the statement that Liu Datian is a "magic doctor", they said that doctors can’t cure all diseases.

Local health law enforcement brigade: it has no medical qualification and its medical place has been banned.

The reporter learned from the Dachuan District Health Law Enforcement Supervision Brigade that after Liu Datian practiced medicine, after investigation, they found that he was a vagrant and a five-guarantee household, and he practiced medicine without a license.

"When we went to law enforcement, we asked him something, but he didn’t say it." Dai Zhonghua, the captain of the Dachuan District Health Law Enforcement Supervision Brigade, said.

At the scene, law enforcement officers publicized on the spot that it was illegal to practice medicine without a license, and posted notices in the place where he practiced medicine, banning Liu Datian’s medical place.

On behalf of Zhonghua, strictly speaking, compulsory measures should be taken against him, but considering that the old man is over 70 years old and has been wandering for a long time, he is in poor health and has not taken compulsory measures. He can only be warned not to practice medicine.

According to the reporter, after the handling by the law enforcement brigade, Liu Datian returned to his village and continued to prescribe drugs. On December 3rd, Dachuan District Health Law Enforcement Supervision Brigade visited Liu Datian’s hometown again.

Deng Zezhang, secretary of the Party Committee of Nanyue Town, introduced that after the occurrence of Liu Datian’s unlicensed medical practice, Nanyue Town organized a meeting of members of the Party Committee in view of Liu Datian’s unlicensed medical practice, and took measures to post an announcement in the town and hometown to inform everyone that Liu Datian was practicing medicine without a license, and used a loudspeaker to walk around the street to publicize and greet the pharmacies on the street. Anyone holding Liu Datian’s list was not allowed to sell drugs.

The reporter saw that the announcement posted by the People’s Government of Nanyue Town showed: "Liu Datian, a villager in Group 4 of Tianbao Village, Nanyue Town, male, aged 74, is a poor person and has been suspected of mental disorder for about 50 years. Liu Datian is now prescribing for others in Pailu Village. It has been found that Liu Datian has no doctor qualification certificate and is not qualified to practice medicine. The District Health Law Enforcement Brigade has been involved in the investigation and found that Liu Datian is suspected of illegally practicing medicine. "

The announcement also mentioned that the prescription prescribed by Liu Datian has great security risks, and no pharmacy, clinic, hospital or clinic may provide drugs for prescriptions prescribed by illegal medical practitioners.

Chinese medicine expert: This is slandering Chinese medicine. There is no "magic doctor" who can cure all diseases.

The reporter contacted Wang Gang, the president and chief physician of Dazhou Hospital of Integrated Traditional Chinese and Western Medicine. After reviewing the prescriptions of Wu Moumou and Yang Moumou, he introduced that the prescription prescribed by Liu Datian was unreasonable, the pharmacology was unknown, the rules were confusing, the drugs were repeated (fragrant, woody), and the dosage was wrong (the Pharmacopoeia had long required prescriptions to be used without money), and it was impossible to see what diseases could be cured by physical strength.

Wang Gang introduced that Chinese medicine pays attention to "looking, smelling, asking and cutting", and collects the condition through these ways, and diagnoses the condition by integrating various situations. "It is irresponsible for patients to prescribe drugs only when they ask about their illness, and if the information about their illness is not collected, they should not be allowed to ruin the cause of Chinese medicine." Wang Gang said.

Diao Benshu, the chief physician of the Department of Traditional Chinese Medicine of the Seventh People’s Hospital of Chengdu and a famous Chinese medicine practitioner in Sichuan, said, "The so-called imperial doctors are all deceptive." Traditional Chinese medicine pays attention to "looking, smelling, asking and feeling", depending on the patient’s look and form, listening to the voice expression, feeling the pulse, watching the thickness of muscles and loose hair, listening to the patient’s voice, etc., and drawing a comprehensive conclusion through the information obtained in these four ways. Prescribing a prescription without looking at the patient himself is too simple. Diao Benshu said: "This practice is mystifying and slandering Chinese medicine."

According to Diao Benshu, in most cases, it is impossible to cure all diseases with one medicine of "imperial doctor", but it can alleviate many symptoms. He said: "There are many factors affecting the curative effect of traditional Chinese medicine. It is wrong to blow traditional Chinese medicine too wonderfully and cure everything. Don’t trust the so-called’ magic doctor’."

(The original title is "The 74-year-old tramp becomes a" magic doctor ",and the consultation fee has risen from 5 yuan to 100. The health law enforcement department has banned it")

China brand cars used to be synonymous with cheapness, but in recent years, China brand cars have made great progress in many aspects relying on the innate advantage of localization. I don’t know if you know anything about what is introduced today. Now let’s follow Xiaobian to see what it has done.

Let’s take a look at the appearance of Ruifeng M3. The front face of Ruifeng M3 looks very stylish and elegant. Coupled with headlights, the overall design is very fashionable and sporty. The car is equipped with LED daytime running lights, automatic opening and closing, etc. Coming to the side of the car, the body size of the car is 5145 mm * 1765 mm * 1900 mm. The car adopts fashionable and simple lines, giving people a very deep feeling on the side of the car. With large-sized thick-walled tires, the shape is quite soft. In the rear part, the rear looks stocky, and the taillights are very cool. Overall, it is still relatively hard-core.

Arriving in the Ruifeng M3 car, the interior design of Ruifeng M3 looks more exquisite and the overall design is very comfortable. The steering wheel of the car is very round and lovely, made of imitation leather, and the shape is very fighting. Take a look at the central control. The design of the center console is reasonable, which makes the interior style impressive and tough. Let Xiaobian introduce the dashboard and seats. The dashboard of this car presents a simple and generous design style, which is very eye-catching. The car uses a fabric seat, equipped with functions such as proportional reclining of the seat, and it is basically enough for daily use.

The rear row space of Ruifeng M3 is fairly spacious, and there is a certain margin in the head and legs, which can be said to be more than enough for daily household use. In addition, the car is equipped with anti-lock braking system (ABS), LED daytime running lights, brake assist (EBA/BAS, etc.), braking force distribution (EBD), traction control (ASR/TCS, etc.), main driver airbag and co-pilot airbag.

The car introduced today is remarkable in terms of space, configuration and power, and home travel is also a good helper. If you are interested, you might as well experience it. I believe it can bring you a good experience.

　　CCTV NewsChina Central Radio and Television’s "International Sharp Review" published two consecutive commentaries this morning on Meng Wanzhou’s detention, directly pointing out that Canada acts as a "human rights defender" of other countries and acts as a vanguard in this "****". Ask Canada’s judiciary and government to stop at the precipice in this "****" and not kidnap themselves.

　　The full text of the two comments is as follows:

　　"International Sharp Review: Whose" Human Rights Defender "Canada Is Being" points out:

　　中国著名民营企业华为CFO孟晚舟女士本月1日在加拿大转机时被加拿大应美方要求逮捕。当地时间星期五（7日），针对孟晚舟被拘押一事的保释听证会在温哥华法庭举行，长达五小时的听证会没有做出裁决，被推迟到下周一（10日）继续举行。

　　孟女士被捕并被拘押，在国际社会掀起一场龙卷风，引发了华为公司、中国民众和中国政府的震惊和愤慨，也引起国际舆论的哗然和指责。这场龙卷风带来的飞沙走石让这么几个真相更加清晰地暴露在世界面前。它们会让加拿大付出意想不到的沉重代价。

　　首先，一向以法律完备、公平正义自居的美国、加拿大将因此事件使其司法公正变成“皇帝的新衣”，其霸权和无赖的内核赤裸裸地暴露在世人面前。

　　早在6年前，美国国会报告称华为的设备会对美构成国家安全威胁，并禁止华为在美销售电信设备。其后，华为曾打算重返美国市场，但终因美国政府阻挠而告吹。不论从哪个角度讲，华为都谈不上违反美国法律，对华为高管的调查和指控纯属子虚乌有。

　　对于加拿大逮捕孟女士的理由，据媒体报道，纽约东区检方申请加拿大逮捕孟晚舟的理由，是其涉嫌违反了针对伊朗的制裁禁令。华为第一时间发表声明称，华为遵守业务所在国的所有适用法律法规，包括联合国、美国和欧盟适用的出口管制和制裁法律法规。而美国对伊朗进行制裁本身就违反国际法。今年10月3日，联合国国际法院裁定美国对伊朗的制裁违反了两国1955年签订的《经济关系和领事权利友好条约》，初步裁决美国应立即停止针对伊朗人道主义物资及民航安全相关商品和服务的制裁。这时，美国才意识到自己先打脸，随即宣布终止该条约。美国国务卿蓬佩奥宣称，这是一个39年前就该作出的决定。美国以“莫须有”的罪名来对待一个法理上不沾边的公司，其推行国际霸权和强权政治的“长臂管辖”愈发站不住脚。

　　作为主权国家的加拿大在执行美国司法申请时不可能不知情，可偏偏表示“这项决定当然没有涉及政治层面的参与，因为我们尊重司法程序的独立性。”这一表态让加拿大“司法独立”成为笑话和鬼话。难怪海外网民对加拿大政府“代美执法”行径深为不满，称“加拿大就是美国的一条忠犬!”、“原本以为加拿大是一个自由民主的国家, 现在看来不过是美国的仆人”、“为什么美国的制裁能够限制中国人跟伊朗的交易，还能在此人在加拿大时将其逮捕？”美国布鲁金斯学会历史学家罗伯特·卡根曾在《华盛顿邮报》撰文称“美国正在成为一个流氓国家”。看来，加拿大也加入了其中。

　　其次，加拿大肆意践踏人权的做法暴露其人权领域的双重标准，它正在成为人权保护行动的破坏者，在损害世界的和平与稳定发展。

　　《金融时报》援引美国一名前情报官员表示，逮捕孟晚舟的行动“太过激进”。在推特上，各国网民们对这一事件的评价是“绑架人质”、“不择手段”等。有网友质疑，“美国是怎么知道一个中国女人会从加拿大转机的呢？美国和加拿大是否只跟踪中国护照, 或者每一个美国人都被监视？”众所周知，加拿大是美国、英国、澳大利亚、加拿大和新西兰的情报机构联盟“五眼联盟”成员，成员内部实现情报信息与窃取数据的互联互通和共享。这就不难解答人们的疑问，也加重了人们的不安全感。更多人从孟晚舟被捕中感受到了基本人权被无情践踏的威胁，也不知有多少人进入了被“五眼联盟”要逮捕的名单中？西方自居的“人权卫士”又倒下一个。

　　第三，这是一场针对中国科技领军企业的定向打击，加拿大在其中扮演“破坏者”的作用越来越明显。

　　美国单方面制裁伊朗，加拿大政府是反对的。但当美国以此为借口对付华为时，加拿大便俯首帖耳、言听计从，其包藏的“祸心”和“私心”昭然若揭。华为作为中国乃至世界最优秀的移动通信基础设施供应商之一，在5G领域处于全球领先地位，拥有全球数一数二的专利和技术。但在“意识形态”作祟下，加拿大正成为阻碍华为全球发展的绊脚石甚至“破坏者”。据美国《华尔街日报》报道，加拿大安全情报服务负责人表示，外国干涉和间谍活动是加拿大繁荣发展和国家利益面临的“最大威胁”，加拿大或许会考虑禁止包括华为在内的一些“网络威胁活动”。面对中国企业的竞争优势，一些国家开始用政治手段设置障碍。有网民称，“如何赢得5G技术战？逮捕你的竞争对手！”。少数国家一面公开高喊“公平竞争”，一面私底下耍着扼杀和捣毁“公平竞争”环境的伎俩，试图保持自身竞争优势。但历史无数次证明，这样的挣扎徒劳无益，受害者总能从逆境中奋起，以更快的速度和更强的势头打破围堵，甚至能实现跨越式发展。

　　第四，加拿大这一逮捕行为引发中国社会高度关注，加拿大的形象一落千丈。

　　最近几天，中国网民普遍质疑和谴责美加的行径，声援华为，强烈要求释放孟晚舟。原本中国人对加拿大怀有好感，几乎每个中国人都知道加拿大医生白求恩当年来华帮助中国抗战的故事。中加1970年建交是在现任加拿大总理特鲁多的父亲皮埃尔·特鲁多的任内实现的。贾斯廷·特鲁多上任后，中国一度掀起“特鲁多热”，希望中加关系更上一层楼。2017年两国旅游互访规模超过150万人次并创下新纪录，2018年被定为“中国—加拿大旅游年”。

　　国之交在于民相亲，失去民心就伤了两国交往的动力。加拿大这次逮捕和拘押孟晚舟女士，将给中加关系带来相当深远和持久的负面影响。

　　孟晚舟事件不仅影响中加关系，也给世界带来不安。事件一出，全球股市与汇市遭遇震荡。加拿大这一鲁莽的拘捕行动，让各国朝野震惊，加剧了市场的担忧和恐慌情绪。加拿大非但捞不到好处、达不到目的，反而会“赔了夫人又折兵”。华为公司和中国政府的态度是理性克制，却又坚定坚决的。华为表示，相信加拿大和美国的法律体系会最终会给出公正的结论。中国官方表示，加拿大警方应美方要求逮捕一个没有违反任何美、加法律的中国公民，对这一严重侵犯人权的行为，中方表示坚决反对并强烈抗议。中方已向美、加两国进行了严正交涉，要求它们恢复孟晚舟女士的人身自由，并警告加方要承担由此造成严重后果的全部责任。

　　"Release her immediately! Restore Ms. Meng Wanzhou’s personal freedom." This is a reasonable and legitimate request from Huawei and the Chinese government. I hope the Canadian government and judicial department, which stand at the crossroads, will not go further and further away from fairness and justice.

　　"International Sharp Review: Canada as a Pioneer in the" **** "points out:

　　Chinese Vice Foreign Minister Le Yucheng urgently summoned Canadian Ambassador to China John McCallum on Saturday (8th) to lodge solemn representations and strong protests against Canada’s detention of the head of Huawei. Le Yucheng pointed out that Canada’s detention of a Chinese citizen who was transiting in Vancouver, Canada, on the grounds of the request of the US, seriously violated the legitimate rights and interests of Chinese citizens, disregarded the law, was unreasonable and intolerable, and was of an extremely bad nature. China strongly urges the Canadian side to immediately release the detainees and earnestly protect the legitimate and legitimate rights and interests of the parties involved. Otherwise, serious consequences will be caused, and the Canadian side will bear full responsibility for this.

　　In this "****" case, Canada’s behavior as a pioneer has caused many people to stumble.

　　Just a few months ago, Canadian Prime Minister Justin Trudeau publicly criticized the United States for imposing tariffs on Canadian steel and aluminum products on the grounds of national security. He said that "Canadians are polite and reasonable, but we will not be pushed around." And he took countermeasures against the United States: not only launched a trade complaint against the United States through the World Trade Organization, but also imposed a 25% tariff on US imports worth $12.60 billion starting from July 1. At that time, international public opinion regarded Canada as a bloody man!

　　可就是这样一条“不会被人摆布”的血性汉子，最近却扮演了一个很不光彩的角色，奉命拘押在温哥华转机的华为公司负责人。其行为令人不齿，更令人不安。

　　美国知名财经记者诺切拉(Joe Nocera)在加拿大贝尔传播旗下的英文财经频道BNN Bloomberg上发文称，“我们有一个词来形容这种违反本人意志拘押某人、并对释放该人设置前提条件的行为，这个词叫做‘绑架’。这是流氓团伙干的，不应该是宣称依法治国的政府所为。”他指出，作为一家不在美国营业的中国企业，华为无须遵守美国对伊朗的制裁措施；即便华为通过一家在制裁名单上的银行同伊朗做生意，那过错也在该银行，而非华为；哪怕华为真的需要遵守美国的制裁措施，强制执行手段中也绝不包含拘押公司首席财务官这一条。诺切拉指出，所谓的违反了制裁规定的说法只是一种借口，因为《纽约时报》说了，拘押孟晚舟只是美国政府为限制中国技术向全球推广而发出的“一个警告”。

　　渥太华一位名叫杜海尼(Alex Duhaney)的读者给加拿大最大的报纸《环球邮报》(The Globe and Mail)写信说，“我为我们的政府参与这一起绑架外国企业高管的行为感到深深的耻辱。如此无耻的行径已经令现在的领导层蒙羞，也将把那些在海外营商的加拿大人置于危险的境地。”

　　近年来，一些西方国家一直不遗余力地在抹黑华为，污蔑华为是间谍，是潜在的巨大的信息安全隐患。但是，与其他西方国家不同，加拿大并没有禁止这家中国科技巨擘参与当地的重要项目。加拿大主要手机运行商的电信设施都有华为的产品，贝尔公司(BCE)与忒勒斯公司(Telus)都跟华为合作开发5G网络，一些加拿大高校也跟华为建立了伙伴关系。

　　最近几个月，加拿大政府为了拓展自身的贸易市场，正加紧同中国接触，积极推动双边自贸协定的谈判。在同美国、墨西哥达成新的贸易协定后，媒体纷纷报道了美方在新协定中设置的针对中国的“毒丸”条款，对此，加拿大外长弗里兰(Chrystia Freeland)还特意给中国国务委员王毅打电话，亲自解释说加方将根据自身决定推进与其他国家的自贸协定谈判。加拿大70多位专家撰写了一份报告，为避开美国“毒丸”条款发展与中国的经贸关系建言献策。上个月，首轮中加经济财金战略对话在北京举行，加拿大财政部长莫钮(Bill Morneau)和国际贸易多元化部长卡尔(Jim Carr)与中国国务委员王勇共同主持。加拿大政府在声明称，“双方重申了进一步深化和扩大加中经济与贸易关系的承诺”。

　　然而，这一切的努力以及已经建立起来的合作如今因拘押中国公司负责人而陷入困境。加拿大艾尔伯塔大学中国学院主任侯秉东(Gordon Houlden)表示，“整个事件对于我们而言是个坏消息”。经此一役，加拿大政府已经不太可能再让华为继续参与5G技术建设了，因为美国不会允许的。反过来，加拿大想同中国在某些领域达成自由贸易协议的目标恐怕也难以实现了。加拿大网友们哀叹，他们期盼的价廉物美的5G要泡汤了。不少人还呼吁加拿大法庭和政治家们要站起来，拒绝美国引渡华为公司负责人的要求。因为，所谓的“违法行为”根本就是政客们发明出来的罪名，目的是为了禁止其他国家/公司/个人之间的相互交易。这就是所谓的“莫须有”。

　　希望加拿大的司法机构和政府在这场“政治绑架”事件中别把自己也给绑架了。

Li Jiangping, head of the Traffic Management Bureau of the Ministry of Public Security (photo by Jiao Fei)

　　CCTV News:The State Council Press Office held a press conference on the 18th, inviting Lian Weiliang, deputy director of the Development and Reform Commission, Liu Xiaoming, deputy director of the Ministry of Transport, Li Jiangping, head of the Traffic Management Bureau of the Ministry of Public Security, Su Jie, director and spokesperson of the Comprehensive Coordination Department of Work Safety of the Emergency Management Department, Yan Hexiang, chief engineer and spokesperson of the State Railway Administration, Dong Zhiyi, deputy director of the Civil Aviation Administration of China, and Li Wenxin, deputy general manager of the Railway Corporation, to introduce the situation and work arrangements in Spring Festival travel rush in 2019, and answer questions from reporters.

　　Li Jiangping introduced that Spring Festival travel rush is the largest personnel flow in a year, and the goal of the public security traffic control department is to do its best to make the people walk safely and smoothly. All localities should make early judgments, strengthen organizational leadership, do a good job in overall planning, and ensure the effectiveness of traffic security work. The main work measures are:

　　First, stick to the safety bottom line and prevent major traffic accidents. Strengthen source control, intensively investigate and urge the rectification of road traffic safety hazards, and prohibit unqualified vehicles and unqualified people from participating in Spring Festival travel rush. Highlight key rectification, strictly investigate and control "two passengers, one danger and one cargo" and key vehicles such as school buses and rural vans. Strict road management, maximize the police force and equipment on the road, crack down on serious traffic violations such as "three overload and one fatigue" and drunk driving according to law, and always maintain a high-pressure situation.

　　Second, escort orderly to prevent serious traffic congestion. In view of three kinds of situations that are easy to cause congestion, such as big traffic flow, traffic accidents and bad weather, we require local public security traffic control departments to make classified policies and actively respond. For the traffic congestion caused by large traffic flow, it is necessary to strengthen traffic command and guidance, ensure the orderly passage of vehicles, and prevent disorder and immobility. For the congestion caused by traffic accidents, it is necessary to link the police with the insurance, compensate quickly and withdraw quickly to prevent small accidents from causing big congestion. For the congestion and detention caused by bad weather, it is necessary to coordinate the relevant units to shovel ice and snow in time to ensure traffic and minimize road closures.

　　Third, strengthen publicity services and create a caring and warm traffic environment. Adhere to strict and standardized fair and civilized law enforcement, adhere to publicity and tips first, and guide the masses to travel safely, civilly and reasonably. Insist on combining management with service, carry out the theme activity of "Safe Traffic Police Peer in Spring Festival travel rush" in depth, and set up Spring Festival travel rush Love Station relying on traffic police law enforcement stations and expressway service areas to provide passengers with convenient and beneficial services within their power, promptly accept people’s emergency help, and make people’s trip to Spring Festival travel rush more intimate and warm.　

　　I. Oil reserves

　　The United States is one of the countries with the largest proven oil reserves in the world. As of January 1, 2004, its proven oil reserves were 22.7 billion barrels, ranking 11th in the world. More than 80% of the country’s reserves are concentrated in four States in the United States: Texas (24%), Alaska (22%), Louisiana (20%) and California (19%). Other oil-producing states include New Mexico, Oklahoma, Wyoming, Kansas, Mississippi and North Dakota. Due to the over-exploitation in the late 1980s and the first half of 1990s, the oil reserves in the United States decreased rapidly. At present, the oil reserves in the United States decreased by about 20% compared with 1990.

　　Second, production

　　The United States is the third largest oil producer in the world after Saudi Arabia and the Russian Federation. According to the statistics of American oil and gas magazine, the American oil output in 2003 was 7.9 million barrels per day, accounting for 9.2% of the world’s total oil output. The output of crude oil is 5.7 million barrels per day, and the rest is natural gas liquid (NGL). At present, the output is the lowest in the past 50 years, which is about 25% lower than the 10.6 million barrels per day in 1985. There are about 500,000 oil producing wells in the United States, but most of them belong to marginal wells. According to statistics in 2003, the main oil producing areas are concentrated in the Gulf of Mexico, Texas land oil fields, the northern slope of Alaska, California, Louisiana land oil fields, Oklahoma and Wyoming. In 2003, the United States drilled 30,151 new oil and gas wells, including 5,694 oil wells, 20,011 natural gas wells and 4,446 dry wells. Compared with 25,536 wells drilled in 2002, it increased by 18%. With the progress and development of geophysical prospecting technology and drilling equipment, the output of deepwater oil fields in the Gulf of Mexico has increased rapidly. At present, the output of deepwater oil fields accounts for two-thirds of the oil production in the Gulf of Mexico in the United States. Because most of the energy resources in the United States are concentrated in the territory of the federal government, and the exploration and exploitation of oil and gas are subject to many restrictions by the federal government, it is difficult to increase oil production significantly. Due to the low return on energy investment, the investment in the oil industry has been greatly reduced since 1980, which has led to the aging of the existing oil supply infrastructure in the United States, such as pipeline transportation and refinery processing, and the serious shortage of production capacity.At the same time, domestic production costs are higher than the international level, and environmental protection requirements are increasingly demanding. As a result, many refineries have been forced to close down. Relevant data show that no new refinery was built in the United States from the late 1980s to the 1990s. The petroleum refining and processing industries in the United States are mainly concentrated in Texas, Louisiana, California, Illinois, Pennsylvania, New Jersey, Washington, Ohio and Indiana. According to the statistics of British Petroleum Company (BP), the refining capacity of the United States in 2002 was 16.76 million barrels per day, accounting for about 20% of the world’s total refining capacity of 8,390 barrels per day. At present, the dominant oil companies in the American market are mainly ExxonMobil, Philips Continental, Chevron Texaco, Shell Oil, Frontier Oil, Marathon Oil and other companies. The U.S. Department of Energy predicted in its energy policy article that the oil production in the United States will drop from the current level of 580 barrels per day to 5.1 million barrels per day in 2020, and the Gulf of Mexico will play an important role in the future, and its share in domestic oil production will increase from the current 27% to 40% in 2010.

　　Third, consumption

　　The United States is the largest oil consumer in the world. In 2003, the consumption was 20.071 million barrels per day (equivalent to 914.3 million tons), an increase of 1.9% over the previous year, accounting for 25.1% of the total oil consumption in the world. In the current composition of energy consumption in the United States, oil accounts for 42%, coal accounts for 24%, natural gas accounts for 20%, nuclear energy accounts for 8-,and hydropower, solar energy and wind energy account for 4%. According to the statistics of British Petroleum Company (BP), in the composition of oil consumption in the United States in 2003, transportation oil accounted for about 67.5% of the total oil consumption, industrial oil accounted for about 24.2%, civil oil accounted for about 3.9%, electric oil accounted for about 2.4%, and commercial oil accounted for about 1.9%. After experiencing the oil crisis in the 1970s, the United States began to pay attention to improving energy utilization and saving energy, and the energy intensity continued to decline. At the end of 1990s, the energy required for producing every dollar decreased by 44% compared with that in 1970, and the annual per capita oil consumption decreased from 31 barrels in 1978 to 26 barrels in 2000, a decrease of 20%. On the whole, since 1973, American economy has increased by 126%, while energy consumption has only increased by 30%.

　　In order to improve the energy utilization rate, the federal government formulated the Energy Star program as early as the 1970s, and in the late 1980s, it set energy-saving standards for related industries, such as automobile manufacturing, household appliances and building lighting. Some energy-intensive production units, such as wood processing and papermaking, chemical industry, petrochemical refinery, metal smelting, food processing, ceramics and glass firing, have either adopted new energy-saving technologies or shut down and turned around, reducing the dependence of the economy on energy to some extent. In addition, the adjustment of macroeconomic structure and the rise of non-energy-intensive industries, such as communication and information technology, microelectronics and financial services, have also greatly reduced the energy intensity of the United States.

　　On the other hand, because the transportation industry in the United States accounts for more than 65% of its total oil consumption, the automobile industry in the United States developed rapidly during the period of low oil prices in the 1980s and 1990s, and the vehicle types became larger and larger, especially the fuel-intensive vehicles such as off-road vehicles and sports cars, which were favored by consumers. Therefore, the demand for petroleum products, mainly gasoline, has greatly increased. The US Department of Energy predicts that in the next 20 years, US oil consumption will increase by 33% and natural gas consumption by 50%, and by 2020, US oil consumption will reach 26-27 million barrels per day.

　　Iv. import

　　The United States has been a net energy importer since 1950s. After 1985, its dependence on imported oil increased significantly. In 2003, its import volume increased from 4.3 million barrels per day in the mid-1980s to 12.2 million barrels per day (equivalent to 605.1 million tons), an increase of 7.9% over the previous year, accounting for 62% of its total domestic oil demand and 26.8% of the world’s total imports. Among them, the import volume of crude oil is 9.645 million barrels per day and that of oil products is 2.609 million barrels per day. The main import sources are Canada (2.1 million barrels per day), Saudi Arabia (1.8 million barrels per day), Mexico (1.6 million barrels per day) and Venezuela (1.4 million barrels per day). Among the sources of oil imports in the United States, more than two-fifths of oil imports come from member countries of the Organization of Petroleum Exporting Countries. From 1973 to 2000, the dependence of American domestic market on imported oil increased from 35% to 52%, natural gas increased from 5% to 15%, and the proportion of energy imports in its total imports exceeded 10%. In order to meet the increasing domestic oil demand and ensure the safety of energy supply, the United States has formulated a multi-faceted global supply system strategy in its energy policy and implemented a diversified policy of oil and gas import sources. In addition to taking Saudi Arabia, Kuwait and other oil-producing countries in the Middle East as the leading sources of supply, it also makes full use of the convenience of the North American Free Trade Area to consolidate the existing energy production and cooperation with Canada and Mexico.Increase investment in onshore and offshore oil and gas fields in Latin America and Central and South America countries such as Venezuela, Trinidad and Tobago, Bolivia, Brazil, Argentina, Chile, Paraguay, Uruguay, Colombia, etc., and ensure the source of oil supply for the United States in this region. And set up the US-Russia oil and gas working group and the US-Kazakhstan oil and gas and commercial energy working group, increase investment in Aegean and African countries and regions, and make use of technological advantages to carry out deep-sea oil and gas exploration and production in the Atlantic basin between Canada and the Caribbean, Brazil and West Africa.

　　V. Inventory

　　Strategic reserve oil

　　After being hit by the oil embargo imposed by the oil-producing countries in East Arab in the early 1970s, President Carter signed the energy policy and energy-saving law in 1975 and decided to establish a strategic oil reserve. On July 21, 1977, about 412,000 barrels of Saudi light crude oil were injected into the salt cave on the coast of the Gulf of Mexico as the first strategic storage. According to the relevant laws, only when the domestic energy supply or import is blocked, or the oil price rises sharply due to the oil embargo, which may seriously threaten national security or economic operation, can the President of the United States decide and order the use of strategic reserve oil. On November 13, 2001, President George W. Bush announced that the strategic oil reserve would be increased to 700 million barrels. At present, the strategic oil storage capacity of the United States is 727 million barrels. The International Energy Agency requires that the United States’ oil reserves (strategic and non-strategic stocks) should reach 90 days’ import. The maximum withdrawal amount of strategic oil reserves is 4.3 million tons/day, and it takes about 13 days from the withdrawal of stocks to entering the US market. In order to establish strategic oil reserves, the United States has invested a total of 21 billion US dollars, of which 4 billion US dollars are used to purchase oil storage facilities and 17 billion US dollars to purchase reserve oil. The reserve oil will come from 20 countries, of which light crude oil accounts for about one-third of the total reserve oil and two-thirds is heavy crude oil (crude oil with sulfur content above 2%). As of August 24, 2004, the United States had 667 million barrels of strategic reserve oil, which was equivalent to 55 days’ import at that time. Among them, 270 million barrels of light crude oil and 397 million barrels of heavy oil.(In 1985, the strategic stock oil reached the import volume equivalent to 118 days at that time). The main oil storage locations are related states in South America, such as Louisiana and Texas, which are close to the Gulf of Mexico. The strategic reserve oil of the United States has played an important role in stabilizing the international oil market. Since the establishment of the strategic oil reserve, only when Iraq attacked Kuwait in early 1991 and caused the price of the international oil market to rise sharply, according to the allocation quota of the international energy agency, President Bush ordered the Ministry of Energy to use 33.75 million barrels of crude oil when launching the operation desert storm to calm the price rise in the oil market. But in the end, the United States only used 17.3 million barrels, which effectively brought the international oil price down sharply.

　　Commercial petroleum inventory

　　According to api gravity data, by the end of July, 2004, the commercial inventory of crude oil in the United States was 298 million barrels, up by 4.6% over the same period of last year, the inventory of gasoline was 212 million barrels, up by 5.2%, and the inventory of other oil products was 158 million barrels. At the end of July, the national inventory of various oil products (excluding strategic oil reserves) was 959.6 million barrels, a slight increase of 0.2% over a year ago.

　　VI. The Impact of Oil Price Fluctuation on American Economy

　　Since 2003, especially since August this year, the sharp and rapid rise in oil prices has caused the international oil market to fall into panic again. The New York Mercantile Exchange’s September West Texas Intermediate crude oil futures price broke through the psychological defense line of $40 and $45 per barrel in just a few weeks, and reached the $50 mark. Finally, on August 20, it fell back after hitting $49.40. Compared with the beginning of the year, oil prices have increased by about 50%.

　　People in the industry have consistent views on the reasons for the rising oil prices, mainly as follows: 1. Compared with other commodities, the monopoly of oil is still strong. In order to maintain the selling price, the Organization of Petroleum Exporting Countries has been adopting the sales strategy of limiting production and insuring prices in recent years, but the supply has decreased. 2. The international market demand shows a slow growth trend, and the oil import demand of emerging countries, especially China and Indian countries, rises sharply. 3. The geopolitical situation is turbulent, and anti-government forces in Iraq threaten to blow up oil production facilities, kidnap foreign companies as hostages and carry out terrorist activities. The political turmoil caused by Venezuela’s domestic election has affected its oil production and export, and the protracted tax evasion case by KOS Oil Company in Russia has caused market panic. 4. Speculation in the oil futures market has intensified. As soon as traders encounter trouble, they will take the opportunity to speculate, which will contribute to the rise and fall of oil prices. 5. The production capacity of the member countries of the Organization of Petroleum Exporting Countries is close to the limit, and their ability to regulate oil supply is declining.

　　As for the possible impact of this oil price on the economy, there are different opinions. As the impact of oil price fluctuation on economy is lagging behind, judging from several oil crises since 1970s, every crisis is always accompanied by high inflation and economic recession. For example, the first oil crisis when the Arab countries imposed an oil embargo led to a serious global recession in 1973-1975, the oil crisis triggered by the Iran-Iraq war in 1979 led to a global recession in 1981-1982, and the oil price shock triggered by the Gulf War plunged the western industrialized countries into a relatively moderate economic recession in 1990-1991. Therefore, some economists believe that this sharp rise in oil prices will inevitably bring considerable negative impact to the world economy. Take the United States as an example. In 2004, its GDP increased by 4.5% in the first quarter, and decreased to 3% in the second quarter. Affected by the oil price shock, many American economists have lowered their economic growth forecasts in the second half of the year, arguing that high oil prices will affect consumer spending, reduce investment, reduce national real income, keep the unemployment rate high, widen the foreign trade deficit, and may lead to inflation. What’s more, it is believed that the American economy may experience stagflation or fall into recession again in 2005. However, some institutions, such as the Federal Reserve Board of the United States, are optimistic that the impact of this oil price shock on the US economy is limited, and it will not lead to a new economic crisis. The reason is that from a macro perspective, there has been no fundamental change in the relationship between supply and demand in the international oil market.The oil supply is sufficient, the demand for oil in the United States has not increased significantly, and it is backed by a considerable oil inventory. More importantly, the tolerance for rising oil prices is greatly enhanced compared with the past, so it can cope with price fluctuations in the international oil market in a short period of time. Once speculation subsides, the oil market will return to its original pattern.

　　The author believes that oil is a strategic scarce resource. Although major oil importing countries have been practicing energy conservation and improving energy utilization for a long time, the status of oil as a major energy source cannot be effectively replaced for a long time to come. With the continuous development of the world economy, especially the rapid economic development of developing countries such as China and India, the demand for oil in the international market is bound to increase. At the same time, the international geopolitical pattern is turbulent, especially the terrorist activities in major oil-producing countries such as the Middle East, which will always be an unstable link in the supply chain of the international oil market. Therefore, in the long run, oil prices will continue to rise with the increase in demand caused by the development of the world economy. The possibility of a sharp rise in oil prices in the short term due to temporary factors and speculation is not ruled out. From the perspective of the United States, as it experienced the oil crisis in the 1970s, it adjusted its macro-energy policy in time, paid attention to the diversification of energy composition, increased the development of natural gas resources, nuclear energy and other alternative energy sources, improved energy utilization rate and focused on energy conservation, diversified import channels, and a huge strategic oil reserve, so its overall resilience to resist the energy shortage crisis was greatly enhanced compared with the past, and short-term oil price fluctuations had relatively little impact on the economy. Therefore, although this oil price shock will definitely affect its economic growth in the second half of 2004, it is estimated that it will not have a reversible impact on its economic activities, and the specific impact will need further close attention.

　　According to the statistics of the U.S. Department of Energy, 48% of the total crude oil consumed in the United States is used to produce gasoline and other fuels. Due to the popularity of multi-purpose vehicles with high horsepower and high fuel consumption, the consumption of gasoline in the United States has increased by 24% since 1990. Since September and November, especially since this year, due to the intensified price fluctuation in the international primary raw material market and domestic natural disasters, especially the hurricane that frequently visited the relevant States in the southern United States last year and this year (which is also the gathering place of many large American oil refineries), the domestic petroleum products in the United States, such as gasoline and heating oil, have shown a tight supply market situation, which has led to. It is estimated that gasoline consumption will increase by 48% over the current level in 2025. Because domestic production is far from meeting the market demand, the proportion of imported gasoline in the total gasoline consumption in the United States has soared from 4% in 1995 to about 10% at present. According to the forecast of the Energy Information Administration, by 2025, the gasoline consumption in the United States will increase from the current 8.9 million barrels per day to 13.3 million barrels per day. By then, gasoline alone will account for half of the crude oil consumption in the United States. At the same time, the proportion of diesel oil, heating oil and aviation fuel oil in the demand for refined oil will also increase greatly. In sharp contrast, since the second half of the 1990s, the domestic refining capacity in the United States has increased by less than 1%.

　　The main reasons for the imbalance between supply and demand in the oil market are:

　　Since the 1970s, due to the persistent surplus of international crude oil market, oil prices have been hovering at a low price for a long time. At this stage, American refineries have maintained a low rate of return and a low rate of return on investment, which greatly inhibited investors from expanding refinery facilities and launching new refineries. In fact, since 1976, the United States has not built a new refinery (just increasing the production scale of existing facilities). At present, the number of oil refineries has decreased by more than half compared with 1981, while gasoline consumption has increased by 45%. According to the statistics of the relevant departments of the US Department of Energy, the number of refineries in the United States has decreased from 324 in 1981 to 148 (including 4 idle ones). These refineries are located in 32 States in the United States, with an overall crude oil processing capacity of 17.12 million barrels per day. In the past ten years, nearly 50 refineries have closed down, and most of the existing enterprises have outdated equipment and various accidents. The reason is mainly attributed to the large-scale reorganization of oil refining enterprises after the two oil crises in the 1970s, such as selling and closing excess production equipment, which led to the reduction of the number of refineries in this industry. In addition to the overcapacity factors that affected the new investment in the oil refining industry in the 1980s and 1990s, various regulations in the United States, such as more stringent environmental laws, clean air laws, relevant regulations on air quality, water quality, waste and automobile exhaust emissions, more additional government licenses and regulations to further reduce the sulfur content in gasoline and diesel, in addition,Refineries also need to produce gasoline and diesel with different standards according to federal standards, state government standards and local government standards, and it takes time to apply for more complicated government licenses. Clean fuel standards (such as the introduction of various environmental protection standards one after another, the increasingly strict emission standards for automobile exhaust, etc.) undoubtedly make refinery production more difficult and new capital investment increase. According to statistics from the United States, in the past 10 years, the refining industry in the United States has invested about $47 billion in environmental protection projects, mainly for producing low-sulfur unleaded gasoline that is more conducive to environmental protection. Under the restriction of internal and external environment, many oil refining enterprises have high input and low output, while some refineries are forced to close down because they cannot adapt to the increasingly fierce industry competition.

　　As can be seen from the above table, refineries in the United States are mainly concentrated in Texas, California and Louisiana. The above three States account for 43.2% of the total number of refineries in the United States, and the crude oil refining capacity accounts for 55.1% of the United States. Texas alone accounts for 17.6% and 27.0% of the total in the United States.

　　Geographically, refineries in the United States are mainly concentrated in Texas and Louisiana near the Gulf of Mexico in the southern United States.

　　About 25% of the existing refinery production capacity in the United States is controlled by foreign enterprises. Mainly operated by large petrochemical multinational companies, such as BP, Shell Chemical Company, Dow Chemical Company, ExxonMobil Company, Texaco Company, Continental Philips Company, Chevron Company, Marathon Schlander Company, Citgo Petroleum Corp., Motiva Enterprises LLC, Murphy Oil USA Inc., Valero, Total Petrochemical Inc.,

　　Western refining co., chalmette refining LLC., premcor refining group Inc., etc.

　　Since the beginning of the 21st century, due to the turbulent world political situation and increasing demand, the price of international crude oil market has been rising, which has led to an increase in market demand for oil products. Although refineries are operating at full capacity, the demand is still in short supply. At the same time, due to the aging equipment of many refineries, accidents continue (for example, BP’s refinery in Texas suffered two accidents, including the explosion in the first half of 2005, which caused dozens of casualties and heavy losses), and the shutdown of refineries along the Mexican coast caused by two hurricanes in August and September 2005, as well as speculation in the international oil futures market, which further aggravated the shortage of oil products in the US oil market, and the prices of motor gasoline and diesel oil soared.

　　The Impact of Hurricane Katrina and Rita on American Petroleum Refining Industry

　　In late August and late September, 2005, two successive hurricanes Katrina and Rita swept through the Gulf of Mexico, which not only brought serious casualties and huge property losses to Louisiana and eastern Texas, but also caused heavy losses to the oil refining industry in the United States.

　　According to the statistics of the US Department of Energy, the oil production in the Gulf of Mexico is 1.5 million barrels per day (equivalent to 75 million tons), which is one of the important oil producing areas in the United States. There are dozens of large refineries of multinational oil companies in Texas, Louisiana and Mississippi near the Gulf of Mexico. For example, there are 17 refineries along the Mexican coast in Texas, including 10 refineries in Houston, with a daily refining capacity of 2.3 million barrels of crude oil, accounting for 13% of the total refining capacity in the United States. There are four refineries in Beaumont and port arthur, with a daily processing capacity of 1.1 million barrels of crude oil, accounting for 7% of the total refining capacity in the United States. Exxon Mobil (ExxonMobil) has 348,500 barrels per day, Motiva (Shell) has 285,000 barrels per day, Total has 233,500 barrels per day, and Valero has 255,000 barrels per day (according to the statistics of the US Department of Energy on January 1, 2005). There are three refineries in Christie, Kobos, with a daily processing capacity of 586,000 barrels of crude oil, accounting for 3% of the total refining capacity in the United States. The three refineries in Lake Charles, Louisiana, which were severely hit by this hurricane, were completely shut down. They were Citgo, with a refining capacity of 324,300 barrels per day, ConocoPhillips, 239,400 barrels per day and Calcasleu, with a refining capacity of 30,000 barrels per day.

　　Affected by the hurricane, the production capacity of about 3.5 million barrels per day (equivalent to 20% of the country’s total refining capacity) was temporarily closed. Among them, the refineries in Port Arthur in eastern Texas and Lake Charles in Louisiana suffered from wind disaster or power failure, and the refining capacity of 1.7 million barrels of crude oil per day completely stopped (accounting for about 10% of the national total refining capacity). And thus triggered a sharp rise in the retail price of gasoline in the southern region.

　　As can be seen from the data in the above table, the Gulf of Mexico in South America occupies a considerable share in the US energy market in terms of crude oil production, refinery quantity and processing capacity, and also has a certain impact on domestic and even international oil prices.

　　After learning from a painful experience, the US government decided to review the existing oil refining industry mechanism in the United States to find out whether there is monopoly and price manipulation in the industry after consumers were hit by the recent sharp rise in oil prices and complained. To this end, the CEOs of Exxon Oil Company, Shell Oil Company, BP America Company, Continental Oil Company and Chevron Company, which account for 42% of the national oil refining capacity, were invited to attend the Senate hearing to explain why they made profits as high as $32.8 billion in a quarter from June to September 2005.

　　In order to cope with the increasing demand for oil products and reduce price fluctuations, members of the Senate and House of Representatives of the United States have proposed new refinery expansion bills, and some have proposed to build new refineries in areas where the unemployment rate is 20% higher than the national average. This will not only achieve the purpose of building refineries, but also increase employment. Some suggest giving preferential tax treatment or tax exemption to attract investors, and some suggest using abandoned military bases as the site of new refineries, which can cause less opposition from nearby residents. However, judging from the current actual situation, a substantial increase in the supply of domestic oil products in the United States can not be achieved overnight. Although the oil supply can be increased to a certain extent by restructuring the refining industry again, combining and expanding existing refineries, improving production processes and processes, even those refineries that have not yet reached full production are limited in their production capacity. The fundamental way to solve the problem is to build a new refinery, but it is expected to face great resistance. The first is the site selection. Many people will agree to build the refinery, a potential pollution source and a "time bomb", in their own backyard. Secondly, it is complicated and time-consuming to apply for relevant permits and obtain approval from competent authorities at all levels. The most important thing is to build a new refinery with large investment, low average profit level and long payback period. The investment in building a new refinery is usually as high as several billion dollars, and even a small refinery needs about one billion dollars.However, the sharp fluctuation of the international oil market price has increased many uncertainties in predicting the investment recovery period and return rate of refineries, which has inhibited the investment desire of potential investors. There is also a recognized view that due to the continuous integration and merger of the oil industry in the past few decades, most small companies with little capital and weak technical strength have been washed out or merged. At present, most of the companies operating in the market are multinational companies, and the market participants in this industry are relatively few, and the competition is not as fierce as other industries. In other words, the monopoly is strong. The rise in oil prices has been expected by these companies for many years, so they will never give up this opportunity to make a lot of money. Building a new refinery will undoubtedly increase competitors and reduce the average profit rate, so there is little interest in these current vested companies.

CCTV News:Recently, the number of patients infected with mycoplasma pneumoniae has increased in many places, especially in children, and the treatment time is long. Many patients and their families have questions. Why is it not good after treatment for a while? I’ve already hit pneumonia vaccine, why can I get mycoplasma pneumoniae pneumonia? How to prevent uninfected people?

Hao Hongwen, chief physician of Pediatrics, Oriental Hospital, Beijing University of Chinese Medicine, gave the following answers to nine common questions about mycoplasma pneumoniae pneumonia.

Question 1: Why did you get mycoplasma pneumonia after playing in pneumonia vaccine?

Hao Hongwen:This is actually a question that we often answer parents in clinic. Usually, children and the elderly are vaccinated with pneumonia vaccine, which is mainly aimed at Streptococcus pneumoniae. However, the pathogen of this popular pneumonia is Mycoplasma pneumoniae, and there is no vaccine against Mycoplasma pneumoniae at present. Therefore, even if vaccinated with pneumonia vaccine, pneumonia caused by Mycoplasma pneumoniae cannot be prevented, because the pathogen is different. Of course, pneumonia vaccine has positive significance in preventing pneumonia and other diseases caused by Streptococcus pneumoniae.

Question 2: I went to check my blood when I had a fever and cough. The antibody against Mycoplasma pneumoniae was also negative, but not positive. Why did it eventually become Mycoplasma pneumoniae pneumonia?

Hao Hongwen:This is because the most positive time of mycoplasma pneumoniae antibody is 5-7 days after infection, so the initial examination may be negative, and some of them will be false negative. Therefore, negative antibody to mycoplasma pneumoniae can not rule out mycoplasma pneumoniae infection.

Question 3: What are the characteristics of mycoplasma pneumonia? How to identify?

Hao Hongwen:Pneumonia caused by mycoplasma infection is characterized by "double weight and light weight".

First of all, the symptoms are serious. Children mainly have a severe fever and cough, and most of them will continue to have a high fever, or the low fever will continue all the time, and the cough will be very heavy. In the first day or two of the onset, the cough may not be obvious, and then the cough will gradually become obvious, mainly manifested as paroxysmal and irritating cough, that is, coughing up in a big array, and even coughing badly will vomit and shed tears. This kind of cough, often with little phlegm at the beginning, is characterized by dry cough, and phlegm will appear in the middle and late stage of the course of the disease, which is the "first weight".

Although this kind of pneumonia has a severe fever and cough, the rales of the lungs are often not heard in the early and middle stages of the disease. Therefore, there is no dry and wet rales after the doctor auscultates the lungs. In layman’s terms, it is no problem to auscultate the lungs. This is a "light".

The characteristic of this disease is twofold and lightness, and the "second weight" is that the chest radiograph is heavier. If a child has a fever for more than three days, high fever for more than three days or low fever repeatedly, and his cough gradually worsens for more than three or four days, he must also consider this kind of pneumonia. Although there is no obvious abnormality in auscultation, doctors will generally advise the child to take a chest film to see if there is any pneumonia. The chest film may show signs of lung inflammation, some of which may be patchy, some may even be large white consolidation, and even pleural effusion. This is the "second weight".

Therefore, we simply sum up the characteristics of mycoplasma pneumoniae pneumonia as "double weight and light weight". If parents and friends find that their children have such characteristics of fever and cough, they must also pay attention to the possibility of mycoplasma pneumoniae pneumonia, and if necessary, conduct chest X-ray or even chest CT examination under the guidance of a doctor.

Question 4: How is Mycoplasma pneumoniae infected? How to prevent it?

Hao Hongwen:The infection of mycoplasma pneumoniae is the same as our common respiratory infections, and it is mainly transmitted through the mouth and nose, so it is easy to be infected in crowded places or in close contact with patients if no protective measures are taken. Therefore, in view of this route of infection, we still have to emphasize that children should go to crowded, closed and unventilated places as little as possible. If the disease is at a high incidence, it is recommended that children wear masks as much as possible and wash their hands frequently when going to these places. Of course, it is necessary to have enough sleep, a reasonable diet, and timely increase or decrease clothes according to the weather conditions, so as to enhance the child’s resistance and avoid the infection of mycoplasma pneumoniae. If someone in the family has been infected with mycoplasma, try to wear a mask or live in a separate room, and open the window frequently for air at home. Especially for families with two children, it is particularly easy to infect each other.

Question 5: Pneumonia only affects the lungs. Will there be other complications?

Hao Hongwen:Mycoplasma pneumoniae pneumonia, its impact on the human body is relatively extensive. The mild pneumonia will gradually recover after a few days of medication, and it will have a greater impact on the severe pneumonia or the pneumonia with long fever time and heavy lung imaging. The common complications are divided into two parts: intrapulmonary and extrapulmonary. The intrapulmonary complications include plastic bronchitis, embolism (which can be independent or combined with other parts), pleural effusion, and some children may be complicated with acute asthma attack and mixed lung infection. Extrapulmonary, including nervous system, circulatory system, blood system, skin, liver damage, kidney damage, etc., among which myocarditis, myocardial damage and liver damage are more common, and in addition, in the nervous system, encephalitis may be common. Skin complications will have some rashes, and the blood system may have some changes in blood cells such as platelets. Each system will also have serious complications, even life-threatening, so we can’t take it lightly.

Question 6: Why did the symptoms get worse after taking cephalosporin from the beginning?

Hao Hongwen:This is because penicillin and cephalosporins play a role by inhibiting the synthesis of cell walls, but when mycoplasma pneumoniae is infected, mycoplasma pneumoniae has no cell walls, so cephalosporins can’t play a role. The use of macrolides such as azithromycin or erythromycin mainly inhibits the synthesis of protein, thus inhibiting the activity of mycoplasma and playing an anti-infection role. Therefore, if mycoplasma pneumoniae is infected, cephalosporins are ineffective. However, some patients may be complicated with bacterial infection and also use cephalosporins.

Question 7: Mycoplasma pneumoniae pneumonia, how should it be treated?

Hao Hongwen:If it is mycoplasma pneumoniae pneumonia, it is generally divided into mild and severe. Mild pneumonia is treated with macrolides such as azithromycin for three days, which may be extended to five days according to the condition, or cyclic erythromycin and roxithromycin can be used. At the same time, you can use some drugs to relieve cough and phlegm. Traditional Chinese medicine can generally use Shegan Mahuang Decoction and Maxing Shigan Decoction after syndrome differentiation.

Severe mycoplasma pneumonia is mainly treated with azithromycin for 7 days, and then stopped for 3-4 days. According to the situation, a second course of treatment or a third course of treatment may be needed, with cough relieving, phlegm resolving, aerosol inhalation, etc., and anticoagulation treatment if necessary. Chinese medicine can be treated with Maxing Shigan Decoction combined with Sanzi Yangqin Decoction and Huanglian Jiedu Decoction. In this process, if the symptoms are not relieved, fever or severe cough persist, it is necessary to consider whether it belongs to drug resistance, mixed infection or other complications according to the situation, and consider switching to other antibiotics, adding hormones, combining antibiotics, bronchoscopic lavage, immunoglobulin and other treatments. This needs the doctor to decide according to the situation.

Quinolones are the first choice for adult treatment, as well as new tetracyclines.

In short, each patient’s situation is different. Under the guidance of treatment principles, specific problems are analyzed and solved. During the period, children should drink water properly, atomize to dilute sputum, and eat digestible food.

Question 8: Why did you use azithromycin and erythromycin, but your condition still hasn’t improved?

Hao Hongwen:This is because the improvement of the disease is related to the following factors: the first is to feel the virulence of this pathogen, the second is whether our body’s resistance is moderate (too weak or too strong), and the third is whether the drug is resistant. If you feel that the pathogen is more virulent, the child’s immunity is weak or too strong, then the drug is not enough to weaken the pathogen or inhibit the excessive immune response, so even the drug can not quickly inhibit the development of the disease. Mycoplasma pneumoniae pneumonia can be divided into mild pneumonia and severe pneumonia, as well as refractory mycoplasma pneumonia. It refers to that after 7 days of treatment with regular macrocyclic lipid antibiotics such as azithromycin, the clinical symptoms and signs or imaging examination have not improved, or other complications have occurred. This year’s guide in 2023 also mentioned "macrolide nonreactive mycoplasma pneumonia", which means that the condition has not improved after 72 hours of treatment with regular macrolide drugs. If drug resistance is considered, new tetracycline drugs such as doxycycline and minocycline can be selected. These drugs are suitable for children over 8 years old, and those under 8 years old are beyond the instructions, which need full evaluation and informed consent of parents. So it is also mycoplasma infection, but the development and changes of the disease are different because of different factors. However, this kind of refractory pneumonia or unresponsive pneumonia is often easy to develop into severe pneumonia. In addition to antibiotic treatment, it is often necessary to cooperate with a variety of therapeutic drugs and means.

Question 9: In the late stage of mycoplasma pneumoniae infection, the child has a bad appetite and a persistent cough. What should I do?

Hao Hongwen:Some children with mycoplasma pneumoniae pneumonia still have some cough symptoms after 2-3 courses of anti-infection treatment, or at the later stage of disease treatment, the children show poor appetite and cough with persistent phlegm. At this time, considering that there may be airway hyperresponsiveness or other sequelae from western medicine, we can continue to adopt corresponding treatment and atomization. Traditional Chinese medicine treatment also has advantages. Traditional Chinese medicine believes that the residual evil is not exhausted and the healthy qi has been injured in the later stage of the disease. Traditional Chinese medicine is used to clear the residual evil and help the healthy qi. At the same time, some other treatments of traditional Chinese medicine, such as cupping and massage, can be used to assist the recovery of pneumonia. (Reporter Yan Yan)

In the process of research and development of existing products, the related underlying technologies are constantly precipitated, and the research and development of new products are constantly fed back. On the whole, the company continues to innovate its products around its own technology and market ability, and realizes the positive cycle of "reserve research and development-mass production".

　　The progress and R&D achievements of the company’s main products in 2021 are as follows:

　　(1) interconnection chip product line: the first generation memory interface chip of DDR5 and the supporting chip of memory module are mass-produced, and the second generation memory interface chip of DDR5 and PCIe5.0Retimer engineering samples are completed.

　　[Product Layout] At present, the company carries out strategic product layout around two areas: high-speed interconnection and high-performance data processing.

　　(1) Interconnected chips belong to "fast chips" and are related to the underlying technology. Based on the technical and market advantages in the field of memory interface chips, the product layout is gradually extended to memory module supporting chips, PCIe and CXL related chips.

　　(2) Data processing chips are "big chips", including Tianjin CPU and AI chips. Is the company developing Tianjin arrest? In the process of CPU, the technical ability in the field of data processing chips is gradually accumulated, and there are more opportunities to meet the needs of server manufacturers and end users. Combined with the company’s technical reserves in DDR and CXL, it laid the foundation for the research and development of AI chips.

　　Generally speaking, the company’s product layout starts with the memory interface chip, and is extended to Tianjin and Shenzhen under the dual drive of technology and market. The server platform, memory module supporting chips, PCIe Retimer chips and AI chips are now further expanded to CKD, MCR RCD/DB and CXL related chips, and we will see the company’s richer product layout in the future. The company’s sub-sectors and products under research have high commercial and technical thresholds. Because the company has certain technical advantages and resource endowments in related sub-sectors, we are confident to participate in the global competition of related products. The company hopes to expand the accessible market scale in the future, consolidate its competitive advantage and lay a solid foundation for long-term healthy and stable development by continuously enriching product categories.

　　(two) the main questions and answers to the exchange.

　　Q: Please look forward to the penetration rate of DDR5 related products.

　　A: In the fourth quarter of 2021, DDR5 memory interface chip and memory module supporting chip have been officially mass-produced and shipped, and will continue to be shipped in the first quarter of 2022. With regard to the penetration rate of DDR5-related products, it is divided into two dimensions: server side, before the server CPU supporting DDR5 is put into use, it is expected that the penetration rate of DDR5 industry will be slowly improved, and the larger penetration rate will climb after the scale of server CPU supporting DDR5 is put into use; On the PC side/laptop side, the desktop platform supporting the first generation of DDR5 was released in the fourth quarter of 2021. At the same time, according to the planning of mainstream CPU manufacturers in the market, the desktop platform supporting the next generation of DDR5 may be launched before the end of this year. These factors will accelerate the upgrade of the desktop from DDR4 to DDR5.

　　Q: How many children does DDR5 memory interface chip have? Compared with DDR 4, is the iteration speed between each offspring of DDR 5 memory interface chip accelerating, and what impact does it have on the company?

　　A: According to the information published by JEDEC, the DDR5 memory interface chip has planned three generations, with support rates of 4,800 mt/s, 5,600 mt/s and 6,400 mt/s respectively, and it is expected that there may be one or two generations in the future. The industry expects that in the early DDR5 generation, the iteration speed between the descendants of memory interface chips may be faster than that of DDR4 generation. On May 9, 2022, the company announced that it was the first in the industry to trial-produce the second generation RCD chip of DDR5. It is expected that this year, in addition to the gradual increase in the first generation of DDR5 products, the second generation of DDR5 memory interface chips will also have a certain amount of sample demand.

　　The acceleration of the iteration speed of DDR5 offspring is of positive significance to the company: first, according to the price law of DDR4 offspring iteration, the initial sales price of the new offspring products is higher than that of the previous offspring due to the upgrading of technology and performance, which can boost the average price of products; Second, as a leader in the segmentation field, the company took the lead in formulating the product standards of the first and second generation memory interface chips of DDR5 in the industry organization JEDEC, which reflected the company’s position in the industry and helped to maintain the company’s leading position in research and development.

　　Q: What is the price law of each offspring of memory interface chip?

　　A: Combined with the price law of DDR4 memory interface chip, the sales price of a certain offspring product gradually decreases after the quantity is added.

　　Q: The company’s AI chips are strategic products in the future. Please introduce the technical architecture, application scenarios and market prospects of AI in detail.

　　A: 1. Technical architecture.

　　The AI chip solution under research by the company consists of AI chips and other related hardware and corresponding adaptation software, and adopts a near memory computing architecture, which is mainly used to solve the CPU bandwidth, performance bottleneck and GPU memory capacity bottleneck problems in reasoning application scenarios of AI computing under big data throughput, and to provide customers with low latency and high efficiency AI computing solutions.

　　AI chip is the core hardware of the above solution, which is mainly composed of AI computing subsystem, CXL controller, DDR memory controller and other modules. The chip is designed specifically for the application of AI in big data scenarios, and integrates AI high-performance computing, heterogeneous computing, CXL high-speed interface technology, DDR memory control technology and other related technologies. It has efficient hardware acceleration functions such as searching and sorting large-capacity data, and has functions such as data compression and data encryption and decryption.

　　At the same time, the company’s AI chip solution will support a perfect AI software ecosystem, and can deeply optimize all kinds of AI algorithms and models in a targeted way, and can support all kinds of mainstream neural network models in the industry, such as visual algorithms, natural language processing and recommendation systems, which is conducive to the subsequent software and hardware ecological construction and marketing work.

　　2. Typical application scenarios of AI chips in the future The typical application scenarios of AI chips under research by the company in the future are as follows:

　　(1) Recommendation system under big data throughput in the Internet field. At present, the conventional scheme in the industry is to hand over the two main steps of "Embedding" and "Embedding Search" in the recommendation system to different platforms for processing, and the GPU, FPGA or ASIC chip with high computing power is responsible for the "Embedding" part, and the CPU+ big data system deploys the "Embedding Search" part. This step is divided, resulting in a lot of data exchange, and due to the hardware, The goal of the company’s AI chip is to integrate the above two steps and balance the computing power and memory capacity at the same time, so that the computing resources and memory can be used efficiently and the efficiency bottleneck of the system can be solved.

　　(2) Biomedical/medical big picture stream processing in medical field. At present, the conventional scheme in the industry is to cut large pictures in CPU, and the sub-images obtained by cutting are transmitted to GPU for AI processing through PCIe interface. Through many interactions, a big picture is finally processed, which is also limited by the interface bandwidth and memory between them.

　　The company’s AI chip can greatly increase the memory capacity and reduce or even eliminate the need for image cutting. At the same time, CXL interface can make full use of cache performance and directly access the DDR memory of the near-memory computing module, thus improving the efficiency of the interface.

　　(3) Big data application scenarios in the field of artificial intelligence Internet of Things.

　　Generally speaking, the goal of the company’s AI chip solution is to provide customers with more efficient and cost-effective solutions compared with traditional solutions in similar application scenarios.

　　3. Market prospect: In recent years, the market scale of AI servers has been expanding. IDC predicts that the global market scale of AI servers will reach $27.7 billion in 2025, with a compound annual growth rate of 20.3%. According to the application field, AI chip can be used in two scenarios: training and reasoning. According to the prediction of relevant institutions, the global cloud AI chip market will reach a compound growth rate of 28% in 2020-2025 and a scale of 26.1 billion dollars in 2025: the market scale of cloud training chips will reach 12.9 billion dollars in 2025, and the compound growth rate will be 25% in 2020-2025; In 2025, the cloud inference chip will reach the market scale of 13.2 billion US dollars, and the compound growth rate in 2020-2025 will be 32%, which is higher than the overall growth rate of cloud AI chips. The company’s AI chip is facing the reasoning application scenario under the application of big data throughput. Because it is a new product, the current market scale is difficult to predict, but the value of AI chip is large. This is a very important product in the strategic layout of data processing chips, and I hope this product can become a new revenue growth point for the company in the future.

　　Q: The newly-developed CKD chip is mentioned in the company’s annual report. Please tell us in detail the function, application and future market space of this chip.

　　Answer: CKD chip is a high-speed Clock Driver defined by JEDEC organization, which can buffer and re-drive the clock signals of the next generation UDIMM and SODIMM (mainly used for desktops and laptops) of DDR5, thus improving the signal integrity and reliability of the clock signals and providing a higher-speed memory solution for desktops and laptops.

　　It is expected that in the middle of DDR5, "CKD+SPD+PMIC" will become the standard of UDIMM and SODIMM for desktops and laptops, and the direct customers will be memory module manufacturers. If CKD chips are fully infiltrated, their demand will be positively related to the global demand for UDIMM and SODIMM for desktops and laptops.

　　According to IDC data, the global shipments of desktops and laptops in 2021 were 349 million units, an increase of 14.8% compared with 2020.

　　At present, JEDEC is still formulating the product standard of CKD chip, and the company has participated in the standard formulation and laid out the research and development. The research and development goal of the company’s CKD chip before the end of 2022 is to complete the flow of engineering samples. At the same time, the company’s new "2022 Restricted Stock Incentive Plan (Draft)" sets one of the assessment indicators for 2023: CKD chips complete the research and development of mass production versions and realize shipment.

　　Q: official website recently released the world’s first MXC chip. Please tell us more about its function, application and future market space.

　　A: On May 6, 2022, the company released the world’s first CXL (Compute Express Link) memory expansion controller chip (MXC). The full name of MXC is Memory Expander Controller, and its Chinese name is Memory Expander Controller. The MXC chip is specially designed for memory AIC expansion card, backplane and EDSFF memory module, which can greatly expand the memory capacity and bandwidth to meet the growing demand of data-intensive applications such as high-performance computing and artificial intelligence. MXC chip is a CXL DRAM memory controller, which belongs to the third device type defined by CXL protocol. The chip supports JEDEC DDR4 and DDR5 standards, and also conforms to CXL2.0 specification, supporting the speed of PCIe 5.0. This chip can provide a high-speed interconnection solution with high bandwidth and low latency for CPU and devices based on CXL protocol, thus realizing memory sharing between CPU and CXL devices, greatly improving system performance, and significantly reducing software stack complexity and total cost of ownership (TCO) of data center.

　　MXC chips are mainly used in memory expansion and pooling application scenarios of big data, AI and cloud services. Before CXL interconnection technology, the bottleneck of memory expansion lies in the limitation of the number of CPUs and memory slots and the limitation of the memory capacity corresponding to each CPU. The difficulty of memory pooling lies in the fact that memory can only be accessed by CPU and cannot be shared by other devices.

　　With CXL interconnection technology, the memory expansion card can be composed of MXC chips and DIMM particles to realize the function of memory expansion or pooling, which is beneficial to the flexible allocation of memory space in data centers and effectively reduces the total cost of ownership.

　　The market demand of MXC chip depends on the market demand for memory expansion and memory pooling. Because it can make the memory configuration of data center more flexible and help customers reduce the total cost of ownership, the company is very optimistic about the future prospect of this product.

　　On May 10th, 2022, Samsung Electronics announced the development of its first 512GB CXL DRAM. The CXL internal control extended controller chip (MXC) of this memory module was provided by the company.

　　One of the assessment indicators in 2023 set by the company’s newly launched Restricted Stock Incentive Plan (Draft) in 2022 is: MXC chips complete the research and development of mass production versions and realize shipment. Lanqi will continue to maintain close cooperation with the leading memory manufacturers in the industry to jointly build an ecosystem based on CXL memory expansion controller and constantly update its products.

　　It is generally believed in the industry that CXL technology has great market potential in the future. According to the relevant materials of the investor briefing held by Micron Technology in May this year, it is believed that the market scale of CXL-related products will reach 2 billion US dollars by 2025 and further exceed 20 billion US dollars by 2030, driven by the rapid development of heterogeneous computing.

　　Q: The newly-developed MCR RCD/DB chip is mentioned in the company’s annual report. Please tell us the function, application and future market space of this product in detail.

　　A: MCR RCD/DB chip is used for MCR memory module, which is a higher bandwidth memory module. With the increasing number of AI processing in the cloud, the demand of high throughput, low latency and high density has spawned the demand for higher bandwidth, faster speed and higher capacity memory module. In order to meet this demand, JEDEC organization is currently formulating relevant technical standards for server MCR memory module.

　　The MCR memory module adopts the "1+10" infrastructure of LRDIMM. Compared with ordinary LRDIMM, the MCR memory module can access two arrays on the memory module at the same time, providing double bandwidth. The first generation of products can support up to 8800MT/s, and it is expected that there will be two or three generations of products with higher speed in the DDR5 generation. The memory interface chips needed for the high bandwidth memory module of the server are MCR RCD chip and MCR DB chip. Compared with ordinary RCD chip and DB chip, the design is more complicated and the speed is higher.

　　At present, JEDEC is still formulating the standard of MCR RCD/DB chip, and the company has participated in the standard formulation and has laid out research and development. Compared with ordinary RCD/DB chips, MCR RCD/DB chips have higher technical requirements, more difficult research and development, and longer research and development cycle, so it is difficult for manufacturers who have not developed RCD/DB to break through in a short time. The research and development goal of the company’s MCR RCD/DB chip before the end of 2022 is to complete the flow of engineering samples. At the same time, the company’s new "Restricted Stock Incentive Plan for 2022 (Draft)" sets one of the assessment indicators in 2023 as follows: MCR RCD/DB chip completes the research and development of mass production version and realizes shipment.

　　Q: What is the mass production and shipment of PCIe4.0Retimer chip in 2021, the future market situation and the research and development progress of PCIe5.0Retimer chip?

　　A: The company’s PCIe4.0Retimer chip achieved sales revenue of 12.2 million RMB in 2021, achieving a substantial breakthrough from zero to one.

　　From an industry perspective, in the short term, the PCIe4.0 ecosystem has just started, and the overall scale of the industry is not large; Looking into the future, it is generally believed in the industry that the demand for PCIe4.0-related equipment will gradually increase this year. At the same time, the mainstream server CPU supporting PCIe5.0 will be listed this year, and the demand for PCIe5.0-related equipment will enter the start-up period, which will also drive the demand for PCIe Retimer chips, and will drive the improvement of PCIe5.0 ecosystem and the commercialization process of related products. Therefore, the whole industry is still very optimistic about the PCIe Retimer chip market in the medium term. In January 2022, PCI-SIG officially released the final (1.0) specification of PCI Express6.0. Compared with PCIe5.0, the transmission speed doubled again, from 32GT/s to 64 GT/s.

　　In 2021, the company’s PCIe5.0Retimer chip has completed the slide of engineering samples, device and system-level test and evaluation, and began to send samples to customers and partners for interoperability testing. Before the end of 2022, the company’s PCIe5.0Retimer chip aims to complete the research and development of mass production version.

　　Q: The company’s R&D direction is the application field of SerDes high-speed interface. Is it the direction of the company’s future product line expansion?

　　A: SerDes is short for SERializer /DESerializer.

　　It is a mainstream serial communication technology of time division multiplexing (TDM) and point-to-point (P2P). That is, at the sending end, multiple low-speed parallel signals are converted into high-speed serial signals, which pass through the transmission medium (optical cable or copper wire), and finally at the receiving end, the high-speed serial signals are converted into low-speed parallel signals again. As an important underlying technology, SerDes is usually used as the physical (PHY) layer of some important protocols (such as PCIe, USB, Ethernet, etc.) and is widely used in high-speed interconnection in the fields of servers, automotive electronics, communications, etc.

　　Because SerDes is an important basic technology in the field of high-speed interconnection, which can be applied to PCIe Retimer and many other products, the company attaches great importance to this technology, and will also make some new product layouts based on the extension of technology.

All-media reporter of rule of law daily Jiang Dongliang Liang Pingni

　　"The boss defaulted on my salary and didn’t ask for it many times. What can I do?" Not long ago, Wang, a villager in Zhangzhuang Town, Yucheng City, Shandong Province, came to the "Law to Help" legal clinic in Zhangzhuang Judicial Office for consultation. Lawyer Hongfeng, who was "sitting in the clinic" that day, fully understood the situation and helped Wang clarify the legal relationship and immediately wrote a civil complaint for him. Knowing that Wang’s family was in financial difficulties and met the conditions for applying for legal aid, the staff of the judicial office immediately assisted him in applying for legal aid.

　　In May, 2022, in order to solve the problem of "urgent difficulties and anxiety" in people’s production and life, Zhangzhuang Judicial Office established the "Law to Help" legal clinic, which adopted a new legal service model integrating legal consultation, legal aid, popularization of law, physical examination under the rule of law, litigation agency and conflict resolution, and set up a "general legal clinic" and a "legal expert clinic", which was run by judicial staff. The "legal expert clinic" is attended by specially invited lawyers and legal service workers every Friday, so that people can enjoy convenient, fast and efficient legal "diagnosis and treatment" at their doorsteps.

　　In Zhangzhuang Town, the solemn promise of "If you have something to talk about, come and help with your true heart rhythm" has been deeply rooted in the hearts of the people. "In the past, when ordinary people encountered legal problems, they didn’t know what to do and who to look for. Now, when they go to the town to catch a gathering, they can go to the judicial office to sit and talk. Consultation costs nothing, and disputes are returned to mediation. There is no need to worry about legal problems anymore!" Wang said.

　　In recent years, Yucheng City, with the construction of "Fengqiao Judicial Office" in the new era as the carrier, has continuously strengthened the empowerment of the rule of law. Through the establishment of the "one institute, one product" project, various legal service resources such as legal aid, notarization, judicial expertise and lawyers have sunk to the forefront, and the grassroots foundation of judicial administration has been continuously consolidated, creating a frontier position to boost grassroots rule of law construction.

　　"The’ Law to Help’ legal clinic opened by Zhangzhuang Judicial Office is one of the key projects of’ One Institute, One Product’." Han Peijun, Party Secretary and Director of the Judicial Bureau of Yucheng City, told the reporter that since the establishment of the "One Institute, One Product" project, Yucheng City has made great efforts to guide and urge the judicial offices in its jurisdiction to reform, innovate and boldly explore, and dig deep into innovative practices in people’s mediation, public legal services, and rule of law town street construction, and form a bright brand to practice and promote. At present, some projects in Juzhen, such as "Diversified Solution of Xiaolong Mediation Room", Xindian’s "Five Governance and Co-construction", Anren’s "Lao Zhao Mediation" and Lunzhen’s "Legal Service Workstation for Small and Medium-sized Enterprises", have also achieved initial results, forming a number of judicial brands of "no one has me, people have me new, and people are new and excellent".

　　"In recent years, with the deepening of the construction of the’ Fengqiao Judicial Office’, the Zhenjie Judicial Office has not only been limited to the traditional judicial administrative functions such as mediation of disputes and popularization of law, but the public legal service force has been tilted to the grassroots level, and the legal construction functions such as the judicial director attending party and government meetings and legality review have gradually expanded to the judicial office, and the supporting office space, personnel and funds have all been implemented." Han Peijun said that the establishment of the brand project has further extended the service tentacles of the judicial office and become a full-time, all-round and full-coverage rule of law platform for serving the grassroots, promoting grassroots governance according to law and building the rule of law in towns and streets.

　　Since 2022, Yucheng City has built 17 distinctive and remarkable brands of judicial offices, covering dispute mediation, enterprise-related legal services, and the construction of the rule of law in towns and streets. The judicial offices have resolved 2,213 contradictions and disputes, answered 212 legal consultations, assisted in handling 4 legal aid cases, issued more than 20 legal opinions, and carried out more than 100 publicity and education activities on the rule of law. The judicial directors and legal advisers in towns and streets attended 125 party and government meetings. At present, 9 of the 11 town and street judicial offices in Yucheng City have been named as "Fengqiao-style judicial offices" in Dezhou New Era.
