Yichexun Recently, the Ministry of Industry and Information Technology issued the "Guidelines for the Construction of Network Security and Data Security Standard System for the Internet of Vehicles", aiming to initially build a network security and data security standard system for the Internet of Vehicles by the end of 2023. Focus on basic commonness, terminal and facility network security, network communication security, data security, application service security, security guarantee and support, and complete the development of more than 50 urgently needed standards. By 2025, a relatively complete network security and data security standard system for the Internet of Vehicles will be formed. Complete the development of more than 100 standards, improve the coverage of standards in sub-sectors, strengthen the service capacity of standards, improve the application level of standards, and support the safe and healthy development of the car networking industry.

The framework of standard system includes six parts: general and basic commonness, terminal and facility network security, network communication security, data security, application service security, security guarantee and support. In key areas and directions, the following contents are put forward:

1, the overall and basic common standards

The general and basic common standards are the general, universal and guiding standards for network security and data security of vehicle networking, including terms and definitions, general architecture and password application.

Terminology and definition standards mainly regulate the main concepts of vehicle networking network security and data security, and provide basis for terminology and definitions in related standards.

Mei Hesun took a photo with his mother.

Book shadow of Xiao Ji

■ Dai Qiu

First, a collection leads to celebrity romance.

In the autumn of 2016, I bought a handwritten note by Cai Juchuan, a famous epigraphy artist in Yangzhou, from the Border Town Bookstore. The payee was Mei Hesun. The content of this handwritten note is about Cai’s management of printing for a generation of famous actress Mei Lanfang. My interest in it is mainly to write anecdotes about the interaction between Cai and Mei. But because of the high price, I can’t help but pay attention to Mei Hesun.

Mei Hesun is a native of Jiangdu, Yangzhou. He is good at both poetry and calligraphy, and often sings with peers and celebrities. I always thought that he was a poet of Yechun Houshe, and later asked Mr. Gu Yiping, an expert on Yechun Houshe, but the answer was not. However, Gu Lao recalled to me a story related to Mei Hesun, which was quite interesting.

In the 1990s, in order to collect information about Yangzhou literature and history, Gu Lao visited Mr. Chen Xiaozhi who lived in the east of Wenjing Lane in Dongguan Street by bike many times. In the early days of liberation, Chen Xiaozhi served as the deputy director of the Literature and History Committee of Yangzhou Municipal Political Consultative Conference. His father, Chen Chenshuo, was a poet, good at calligraphy and painting, and an important member of Yechun Houshe.

Gu Lao remembers that every time he visited Chen Xiaozhi, he was in the bedroom of Chen Zhai West Room. At that time, a vertical shaft about 120 cm high and 60 cm wide hung on the wall, which caught his attention. Once, he couldn’t help but be curious. When he took a closer look, it turned out to be a rubbings of "Song Su A Cui Xiao Xiang Yan" with inscriptions, inscriptions, poems and inscriptions by nearly 20 famous artists. Seven of them are important members of Yangzhou Yechun Houshe Society, namely Qin Gengnian, Xuan Guyu, Guan Lishing, He Jinyi, Chen Yaoxian, Yao Yinda and Wang Jingqi, which aroused great interest from Gu Lao. This is not only an important material for poets in the post-Yechun society, but also an excellent rural literature.

When Gu Lao asked about the history of this rubbing, Mr. Chen Xiaozhi said, "I have to ask my brother-in-law, Mei Yingchao." And told the detailed address of Mei Yingchao. So, on June 6th, 2001, Gu Lao wrote to Professor Mei Yingchao in north china university of technology, Beijing, asking him to tell the story of this rubbing vertical axis. Soon, on June 18th of that year, Mei Yingchao wrote back. In his letter, he described the ins and outs of this vertical shaft in detail: "The letter talked about the vertical shaft of the rubbings of’ Song Su A Cui Shi Yan’ mounted by my father, and A Cui Yan was spread to Ma Xianglan, a famous prostitute in Qinhuai in the late Ming Dynasty, and she felt sorry for herself. This rubbing was probably picked up by my father when he bought old books in Xiuzhou Bookstore in Shanghai during the Anti-Japanese War, and he was very happy. After mounting it, he invited celebrities to write poems, including those who took refuge in Yangzhou and came to Shanghai at that time. It is also a good thing for literati to say that it is a good thing. Back in those days, my father and I talked, and his understanding of this inkstone and Ma Xianglan was based on an article. This article is the preface of the famous book Shu Xue written by Mr. Wang Zhong (Rong Fu), a great writer in Yangzhou during the Qianlong period of Qing Dynasty. There are a few words in the preface:’ I am a solitary man, living in an inch of land, unable to cure my life, and my old and weak life hangs on my fingers … I am interested in different things, and I am sad and happy by people … What is the difference between me and Sri Lankan people?’ I want to ask my brother to read this article in his spare time, and I can understand it with deep feelings. A deeper understanding of my father’s state of mind at that time is not simply a matter of’ literati’s good deeds’. "

This letter is deeply emotional and concise. The past of the Sri Lankan people is emotional. Mei Yingchao’s father is Mei Hesun, a "good scholar".

Coincidentally, at the age of 2020, I saw another frame of Mei Hesun’s calligraphy fan in the workshop. The small letters were accurate and aboveboard. The content is to copy his own poems as a gift to Wei Yuzhi, a poet of the post-Spring Society, and the literati atmosphere is really unforgettable. At first, the painter was reluctant to sell, and then he was waiting for the price. After many twists and turns, fortunately, I started. I think this is a kind of fate.

Second, learning is taught by the mother, and the old house of Qing Dynasty grows up.

Mei Hesun, whose name is Han, whose name is Hesun, whose name is Yuan, and whose name is Xing. Born in 1894, that is, Jiawu in the 20th year of Guangxu reign in Qing Dynasty, The Fairy Temple (now Jiangdu County) in Yangzhou, Jiangsu Province. Mei Yaochen, a poet of the Northern Song Dynasty, is the most famous descendant of Mei family who came from Xuancheng, Anhui. Mei Hesun’s grandfather’s name is Plum Crane, which has a sound village; Father Mei Zhaoluan, a scholar, died young at the age of 29.

Mei Hesun lost his father at the age of six, and he relied on his mother, Mrs. Liu, a loving mother and a strict teacher.

Speaking of Mei Hesun’s mother, she can be called a strange girl. She is the great granddaughter of Liu Wenqi, a great scholar of Yizheng Confucian classics, and the first cousin of Liu Shipei, a master of modern Chinese studies. Liu is a well-known academic family in China. Since Jia Dao, Liu in Yizheng has been comparable to Huishi in sinology. From Liu Wenqi’s time to Liu Shipei, he passed on the scriptures in one generation and four generations, and became a great success by carefully "Zuo’s family", which was known as "Liu’s family in Qingzhao Old House".

In the 1930s, Mei Hesun hung a pair of couplets in the living room of Shanghai Yuzhong, and wrote a sentence and a book for Qin Gengnian, a epigraph scientist in Yangzhou: "Old houses are green, and poems from other families are passed on; Mountain house cypress, read Mei’s old book. " What I said is the truth of Mei Hesun’s family background.

Mei Mu’s famous teacher, Shuo, was influenced by his family. He was proficient in classics and history since childhood, devoted to poetry, loved calligraphy and studied Wei Bei.

Mr. Zhu Huang (Zi Juping), a close friend of Liu Shipei and a well-known resident in Jiangdu, once wrote a biography of Mei Jie’s mother, praising Mei Mu: "Less family education, more good at Mao Shi and Li Ji, and always follow the etiquette." However, Meimei is still a good wife and mother in the end: "In nineteen years, she belongs to literature (referring to marrying the Mei family), and she is as good as ordinary people. I have never seen what I have learned, and I am close to my husband, and my family is silent. "

In this biography, Zhu Juping also tells a story about the virtuous mother Mei. In September, 1911, there was Sun Tiansheng’s rebellion in Yangzhou, and traitors and bandits took the opportunity to make trouble. At that time, Mei lived in the east of the city, and the situation was critical. Mrs. Liu wanted to take her family away from home to avoid accidents, but the old woman resolutely refused and vowed to die. At that time, Mr. Zhu happened to pass by Mei’s house. In a hurry, Mei’s mother entrusted her young crane grandson to him, saying mournfully, "I’m tired of this son, and I’m just waiting for Gudumen."

At that time, Sun Shang, the crane, was in her prime, and her mother was a poor aunt and a weak child. But she was a pillar in the meantime, and she died to save the portal, which is hard to know. Therefore, Zhu Juping wrote a biography for her, calling it "Jiemu", which was emotional.

Mei Hesun was taught by his mother when he was a child. After more than ten years, Mei Hesun was able to write and write, which was praised by the village. Mei Hesun later recalled his son Mei Yingchao: He entered the school as a teacher and presented Er Ya to his husband first. Please teach him to read it first. Mr. Wang doesn’t understand. At that time, it generally started from the "Four Books", "University" and "The Doctrine of the Mean". Liu is an academic family, and children’s reading is also different from the general. Therefore, to be more precise, Mei Hesun’s growth was cultivated by his family’s old house.

Mei Hesun has read through the history of classics since he was a weak champion, and he has taught himself to attack hardships. Later, he asked Mr. Zhu Juping, a great scholar who studied in the countryside, to learn all kinds of arts, to concentrate on learning, and finally to achieve something.

In 1921, Mei Hesun was twenty-eight years old and went out to make a living. Worked in Jiangdu County. In 1924, he served as a clerk and auditor of Bank of Communications in Nanjing. In 1930, he served as secretary of the board of directors of Guohua Bank in Shanghai; Clerical officer, Central Banking Bureau; Secretary, Commissioner, assistant manager of the Central Trust Bureau for more than 30 years. In 1957, he was hired by the Shanghai Municipal People’s Committee as a member of the Shanghai Literature and History Museum. He died in Shanghai in September 1964.

Third, poetry and calligraphy paint things, making them famous at sea.

Mei Hesun has been traveling in Shanghai for 30 years, and has been working in a bank to make a living, but his good nature still lies in literature and art. In 1944, Mei Hesun wrote nine chapters of Shu Huai, and now I record one of them to get a glimpse of his mind:

"Lease the beach, snap your fingers for two generations, hold the slips and become public, and send them to the spring house. Among them, there are many monsters, and they are more than baht, and the colonization is the camp. My heart is indifferent and indomitable, and my son is lofty. In the Sun, the Moon, eight years of chaos, cloud Hu Bugui, thousands of miles with joy. South Gangbei Luo, the countryside is full of fish and smoke, and I am cherished and cherished, and I am waiting for you. "

Mei Hesun is first and foremost a poet. In 1957, in the column of "Works" in the personnel file of the Shanghai Museum of Literature and History, Mei Hesun noted that there were three volumes of poems and one volume of words in the Jade Kuilong Museum (to be published). According to the memory of his son, Professor Mei Yingchao of north china university of technology, his father likes to write lyrics after 60 years, and about 100 poems are kept in the Shanghai residence. Unfortunately, these poems were all destroyed by fire in September 1966.

Judging from the surviving works, Mei Hesun’s ancient poems pursue Mu Han and Wei, while his modern poems live in the Song Dynasty. Mei Yingchao remembers that his father once showed him the fan of his recent work "Watching the Moon in the Mid-Autumn Festival in Kuanglu" inscribed by his poet friend Chen Sanli: "The cage lake shakes the autumn moon in the sea and moves to the place where Kuangjun lies." Praise, Chen Sanli’s poetics is patriarchal Song people.

Mei Hesun is also a calligrapher. Mei Hesun’s mother is good at calligraphy. He heard from her uncle Liu Shipei that before her mother became a monk, Zeng Shu wrote the banner "Willow Yiyi" with a diameter of eight inches, which hung in Liu Shipei’s room for decades, and Liu Shipei deeply liked it. Liu Shipei said to Mei Hesun, "This is a good sentence in the Book of Songs. You can always think about the artistic conception of these four words when you learn to write poetry, and you should make progress."

Grandmother Mei He’s parents always pay attention to calligraphy. When he was a child, he went back to his old house with his mother, and he often came into contact with many famous works such as Bao Shichen and Wu Rangzhi. The Huashan Monument, collected by Liu’s family, is a treasure of the world, and all the uncles take calligraphy as their ability. Mei Hesun is deeply impressed, and his diligent study, writing practice and extensive reading of posts go hand in hand at the same time. Around the age of 30, people from all sides have been asking for books in an endless stream.

According to Mei Yingchao’s recollection article, when my father was in Shanghai, he talked about art papers, painted poems and books, and friends gathered at regular intervals, which was called "Songbin Tea Collection". I remember an elegant collection in the spring of Xinsinian (1941), and my father happened to talk about "a poem entitled" Wu Rangzhi Peach Blossom Willow Fan Fu "in the collection of Ji ‘an by Mr. Mei Zhi, an ancestor of our family during Daoguang years":

"My friend, I can paint with powder, poplar is green, and peach is red. Don’t close the night and get exposed, fake spring and shake the wind, show off your beauty and be tolerant. Hu Wei Xia Jie, focusing on Qian Mian; Algae think like yee, jasper becomes smoke. Cherish the fleeting moment, linger on the emotions as soon as possible, and believe in the wonderful traces of spirituality, which will be beautiful in Xiquan. "

On the spot, the painter Pan Junnuo dyed Han and painted it as a fan of peach blossoms and willows, while Mei Hesun gave it all to his left in small letters. Calligraphy and painting are both beautiful, which is really elegant and elegant.

Mei Hesun’s calligraphy can be used as a cursive couplet, and he can learn from Wei and Jin dynasties in a real way, and he can get its likeness in Cao Ebei and Thirteen Lines in Jade Edition. In the 1970s, Yangzhou Calligraphy Association edited and published "Preliminary Collection of Ancient and Modern Calligraphy and Printing Works in Yangzhou", which included Mei Hesun’s running script.

Due to his persistent pursuit of literature and art, he was good at exposition. During his stay in Shanghai, Mei Hesun was also a connoisseur of literature and art, and he learned a lot about epigraphy, calligraphy and painting, and edition. Among them, friends and painters who are especially discerning about the authenticity of ancient and modern paintings and calligraphy often come to ask for advice. Individuals occasionally hoard, mostly rare sketches. Apart from the rubbings of the "Southern Song Dynasty Su ‘a Cui Small Elephant Ink Stone" collected by Qing Shen Shiyou mentioned above, there is another collection that is quite talked about:

On one occasion, Mei Hesun accidentally visited Yangzhou, and bought a piece of calligraphy in a cold stall. It was old and cracked, and it had been a long time. The word "square domain" was unknown to people and regarded as dirt. Mei Hesun inferred from the charm of calligraphy, the content of the poem, the age of the paper, the color of the seal, and the location of discovery, and thought that the author of this word was actually "Hou Fangyu". One of the four famous sons of the late Ming Dynasty, the author of Collected Works of Zhuang Regret Hall, and the master of the legendary Peach Blossom Fan. Show friends, all amazing.

Fourth, writing in his later years, personally testifying Liu’s historical materials.

In the summer of 1957, Mei Hesun, aged 64, was introduced by the Shanghai Municipal Bureau of Culture and the New City Political Consultative Conference and was hired as a librarian of the Shanghai Literature and History Museum. One of his important jobs in his later years was to write the historical materials of "three relatives", mainly about the memories of Liu’s family in Yizheng, the old house of Qing Qing.

Yizheng Liu is a famous academic family, who lives in the old house of Qing Qing in Dongquanmen, Yangzhou. From the Qianlong period of the Qing Dynasty to the Jiaqing period, generations of famous experts in Confucian classics and masters of Chinese studies appeared in the Liu family. They made great contributions to the academic history of Yangzhou.

The so-called study of Confucian classics is a science that specializes in the interpretation of Confucian classics in the Spring and Autumn Period. The Liu family was famous in the academic circles of Daoguang, Xianfeng, Tongzhi and Guangxu Dynasties in Qing Dynasty. They studied and interpreted Zuo’s Biography in the Spring and Autumn Period, and wrote many handed down works such as Textual Research on Zuo’s Biography. Their names appeared in Biography of the Scholars, which is unique in the history of the Qing Dynasty.

The so-called "three generations once", that is, Liu Wenqi, Liu Yusong and Liu Shou’s great-grandfather Sun San, are the representatives of Yangzhou School. When Mei Hesun was a child, he often went home with his mother. He is well-read and memorized, and he knows a lot about Liu’s family life and anecdotes for generations. I have heard a lot about it, and many anecdotes are often talked with my children at ordinary times.

Mei Hesun’s memoir titled "Notes on Liu V in Qingzhong Old House" is a portrayal of life since Meng Zhan’s Mr. Liu Wenqi descended to V, especially the legendary experience of Naijiu and Liu Shipei, a master of modern Chinese studies. Liu Shipei, as an important figure in the academic and ideological circles in the late Qing Dynasty, had a great influence on the transformation of China’s modern ideology and culture. However, his life was mixed with politics, with mixed praise and praise. Mei Hesun did not shy away from his relatives, but wrote a straight book about what he saw and heard, which has extremely high historical value.

Mei Hesun spent a lot of energy in writing "Notes on Liu V in Qingzhao Old House Yizheng". It took four years before and after, and the first draft was compiled into two volumes. After the draft was completed, it was distributed to relevant people for review, and it was paid in early autumn of 1962 and mimeographed into a book.

After the first edition of Xiao Ji, in addition to sending it to major libraries in China, it was also distributed to relevant experts and scholars for comments, which received widespread attention and praise from domestic academic circles. For example, Mr. Chen Naigan wrote: "If you read the final book, if you meet with the former sages, you will be one of the fastest in the dust. Narrative Xu Wei Qu, especially admired, is also a new force in Part B. " Mr. Zhou Zuoren said: "Although Zun Zhu was written in imitation of the biographies of other scholars in Hongbei River, it was stronger in expression, and it really won. Its miscellaneous notes are especially rare. I have counted it and I am very impressed. "

Originally, Mei Hesun wanted to synthesize the opinions of all parties and further improve the book in order to revise and reprint it. However, his body is already a lingering sickbed, and he is getting tired. More than two years later, on September 18, 1964, Mei Hesun died with regret. Soon, after ten years of turmoil, Mei Hesun’s books disappeared, and his manuscripts were also lost.

It was not until 18 years later that, with the efforts of many parties, in July 2004, the "Notes on Liu V in Qingzhao Old House Yizheng", which condensed Mei Hesun’s life feelings and painstaking efforts, was finally officially published by Shanghai Ancient Books Publishing House. The new edition of Xiao Ji was revised and arranged by his son Mei Yingchao, including Liu Shipei’s posthumous works outside the collection, and also printed the handwritten letters written by experts and scholars to Mei Hesun, which finally comforted Mei Hesun’s spirit in heaven.

I quote Yongmei’s poems about He Sun from Yangzhou Art Circles by Liu Jiechun, a poet of the post-Spring Society, as a conclusion:

Find a sentence and spend a moment, and send it back to the public.

Than to smell crazy, and sing bamboo branches to Chunming.

Editor in charge:

　　Editor’s Note In the report of the 19th National Congress of the Communist Party of China, General Secretary of the Supreme Leader pointed out that innovation is the first driving force for development and the strategic support for building a modern economic system. In order to speed up the construction of an innovative country and achieve the goal of providing strong support for building a powerful country in science and technology, quality, space, network, transportation, digital China and intelligent society. Recently, experts and scholars in the scientific and technological fields have seriously studied and understood the spirit of the report of the 19th National Congress. They said that we should conscientiously implement the spirit of the 19th National Congress of the Communist Party of China, speed up the consolidation of the foundation of China’s scientific and technological undertakings, and roll up our sleeves and work hard — —

　　The new era entrusts scientific and technological workers with new tasks

　　Gaofu

　　The report of the 19th National Congress of the Communist Party of China is magnificent and sends out the strongest voice of the times! China’s socialist construction has entered a new era, and under the guidance of Socialism with Chinese characteristics Thought, the supreme leader in the new era, the economy and society will surely get unprecedented development. In the report of the 19th National Congress of the Communist Party of China, General Secretary of the Supreme Leader pointed out that innovation is the first driving force for development and the strategic support for building a modern economic system. This is the new task given to scientific and technological workers by the new era, new mission and new journey.

　　Throughout the development of science and technology in developed countries, the strategic reserve of science and technology has always been a rolling source of social and economic development in developed countries. Therefore, in the future development, China must strengthen the strategic layout of science and technology. In the past few years, we have made a good layout of many large-scale scientific installations, and a large number of scientific research achievements have emerged one after another, which not only "topped the sky" to enhance China’s international influence, but also "stood on the ground" to serve the main battlefield of society, people and economy. For example, the construction of Shanghai light source has helped us to interpret the transmission mechanism of H7N9 virus from birds to people and played an important role in formulating relevant prevention and control policies for the country.

　　In the next step, as far as my major is concerned, we should strengthen the research work on disease control and prevention, which is very important for ensuring the life and health of our people and economic and social development.

　　People’s health is an important symbol of national prosperity and national prosperity. Today, with the development of China’s economy and society, people’s specific requirements for health and medical needs have also changed. This puts forward higher requirements for disease control and prevention in China. To protect people’s health and implement the strategy of healthy China, we must build a first-class disease control and prevention system. First-class disease control needs first-class scientific and technological support, which will also be integrated into the construction of national innovation system and the strengthening of strategic scientific and technological forces. In the future, we will face the forefront of world science and technology, the main battlefield of economy, and the major needs of the country, do a good job in basic research and applied research, and serve the country and the people.

　　The 19th National Congress of the Communist Party of China is a conference of "Do not forget your initiative mind, bearing in mind the mission, holding high the banner and forging ahead in unity". As workers in the front line of science and technology and public health, we will conscientiously implement the spirit of the 19th National Congress of the Communist Party of China, consolidate the foundation of science and technology and public health in China, and roll up our sleeves and work hard!

　　Create a new situation in the development of intellectual property.

　　Shen Changyu

　　The report of the 19th National Congress of the Communist Party of China made by General Secretary of the Supreme Leader is profound and strategic, and it is a political declaration and action program that guides the cause of Socialism with Chinese characteristics to enter a new era, start a new journey and write a new chapter. In particular, the report of the 19th National Congress of the Communist Party of China clearly put forward that we should advocate innovative culture and strengthen the creation, protection and application of intellectual property rights. This points out the direction for intellectual property work and is the fundamental follow-up and action guide for doing a good job in intellectual property work. In the future, we will focus on strengthening the creation, protection and application of intellectual property rights, improve the comprehensive strength of intellectual property rights and help the country’s innovation and development.

　　First, we must strengthen the creation of intellectual property rights. It is necessary to aim at the forefront of the world’s science and technology, strengthen key common technologies, frontier leading technologies, modern engineering technologies and subversive technological innovations, and provide the source for improving the quality of intellectual property rights. We must adhere to the principle of quality first and benefit first, carry out the patent quality improvement project in depth, and strive to promote the transformation of intellectual property creation from multi-directional to excellent and from large to strong.

　　Second, we must strengthen intellectual property protection. Protection is the core of intellectual property work. We must conscientiously promote the work of strict protection, large protection, rapid protection and equal protection of intellectual property rights, and actively build a good environment for strict protection of intellectual property rights according to law. In particular, we should improve the laws and regulations on intellectual property protection, improve the quality and efficiency of intellectual property review, strengthen the protection of intellectual property rights in emerging fields and formats, increase the punishment of infringement and illegal acts, and raise the public’s awareness of intellectual property rights, so as to promote the transformation of intellectual property protection from continuous strengthening to comprehensive and strict.

　　Third, we must strengthen the use of intellectual property rights. We must adhere to the "three-pronged approach" and promote the transformation of the use of intellectual property rights from single benefit to comprehensive benefit. Continue to deepen the reform of the distribution of intellectual property rights and interests, build a scientific and reasonable distribution mechanism of rights and interests, and fundamentally mobilize the enthusiasm and initiative of units and inventors to implement the transformation of achievements. At the same time, establish and improve the intellectual property operation platform system to provide a good platform support for the transfer and transformation of intellectual property rights, acquisition custody, transaction circulation, pledge financing, analysis and evaluation, and promote the comprehensive use of intellectual property rights. In addition, facing the real economy, we should vigorously promote the development of intellectual property-intensive industries, improve the level of product supply, and meet the people’s growing needs for a better life by implementing patent navigation projects and forming industrial intellectual property alliances.

　　Create a good research environment for young talents

　　Liu Minghua

　　The report of the 19th National Congress of the Communist Party of China put forward that a large number of strategic scientific and technological talents, leading scientific and technological talents, young scientific and technological talents and high-level innovative teams with international standards should be trained. This makes me deeply touched, because talents are the core of cutting-edge technology, and the essence of future scientific and technological competition is the competition of high-end talents.

　　In the field of nanotechnology, which I am engaged in scientific research, foreign scientists are the main force in its early development. However, with the increasing attention and investment in this field in China, China scientists have occupied a very important position in the field of nanotechnology and gained wide recognition all over the world. In the future, the development of nanotechnology should integrate the wisdom of Chinese scientists and innovative entrepreneurs all over the world, strengthen the cooperation in Industry-University-Research, and pay attention to cultivating young talents to deliver a steady stream of innovation for building a powerful country in science and technology.

　　As a matter of fact, China is one of the earliest countries in the world to carry out nanotechnology research. In the Outline of the National Medium-and Long-Term Scientific and Technological Development Plan (2006-2020), nanotechnology is promoted as a major scientific research plan. At present, China has become a big country in nanotechnology research and development in the world, some basic research has leapt to the international leading level, and the total output of nanotechnology has also ranked first in the world.

　　In recent years, the National Nanoscience Center has continuously increased its cooperation with major universities, paying more attention to the quality of scientific research achievements and the practical contribution of young talents. At the same time, strengthen the cultivation of young innovative talents and encourage young people to undertake more academic innovation work and responsibilities. Especially for returned talents, the center has set up a series of special forums to encourage young people to preside over and invite famous experts at home and abroad to discuss.

　　Over the years, the country has made great efforts in attracting talents. The key to cultivating innovative talents needs to make more efforts in creating an environment for the growth of talents. On the one hand, it is necessary to strengthen the layout of strategic scientific and technological forces and build an important talent echelon that adapts to the national strategic development; On the other hand, it is necessary to solve the learning environment and life problems in the process of talent growth. Integrate and unify all kinds of talent plans, create a good environment for young talents to study with peace of mind and concentrate on innovation, and at the same time solve a series of worries of scientific researchers in their lives, so that they can love science and innovation more and be willing to devote more time to innovation activities.

　　Step up the reform of science and technology system.

　　Qiu Dewen

　　The report of the 19th National Congress of the Communist Party of China pays attention not only to scientific and technological innovation, but also to agricultural development. As an agricultural researcher, I am extremely excited and proud to see that many of our scientific research projects and research fields are consistent with the goals mentioned in the report of the 19th National Congress of the Communist Party of China.

　　The report of the 19th National Congress of the Communist Party of China proposed to deepen the reform of the scientific and technological system, establish a technological innovation system with enterprises as the main body, market orientation and deep integration of Industry-University-Research, strengthen the support for the innovation of small and medium-sized enterprises, and promote the transformation of scientific and technological achievements.

　　At present, although the scientific research environment in China has been greatly improved, the integration of Industry-University-Research needs to be improved, and the "last mile" problem is common among all links. For example, in the field of agricultural scientific research, there are problems such as long research cycle and large investment, but slow effect, slow income and high risk in industrialization promotion. This has led to a lot of social capital unwilling to enter the agricultural field, and many good agricultural scientific research achievements cannot "take root". In this regard, it is necessary to promote the reform of the national science and technology system, make the connection between Industry-University-Research smoother, and promote deep integration.

　　In recent years, our Academy of Agricultural Sciences regards scientific and technological system reform and agricultural scientific and technological innovation as two major power sources to promote the key tasks of building a world-class modern agricultural scientific research institute, promotes system reform with mechanism innovation, establishes and improves the open collaborative governance model of the institute, promotes the scientific research organization model of resource sharing and collaborative innovation, and creates a level playing field that encourages innovation and transformation. At the same time, improve the scientific and technological evaluation mechanism, carry out third-party evaluation, take innovation effect, innovation ability and innovation efficiency as the core content, establish a classified evaluation system for the implementation effect of key tasks of scientific planning, effectively use the evaluation results, adjust key support areas in time, and improve the effectiveness of resource allocation.

　　In addition, the report also proposes to promote the transformation of scientific and technological achievements. We should explore the incentive and protection system for scientific and technological personnel in national scientific research institutions to innovate and start businesses, encourage and support scientific and technological personnel of various identities to reflect innovation value through the application of achievements, and create a level playing field to encourage innovation and transformation. Improve the scientific evaluation method of achievement transformation and innovation and entrepreneurship, and smooth the promotion channels of professional and technical positions of relevant personnel.

　　Comprehensively improve the level of meteorological services.

　　Yu rucong

　　As a non-party member, I had the honor to attend The 19th National Congress of the Communist Party of China and listen to the report of the 19th National Congress made by the Supreme Leader.

　　The report of the 19th National Congress of the Communist Party of China pointed out that strengthening applied basic research, expanding the implementation of major national scientific and technological projects, and highlighting key common technologies, cutting-edge leading technologies, modern engineering technologies and subversive technological innovations will provide strong support for building a powerful country in science and technology, quality, space, network, transportation, digital China and smart society.

　　Meteorology is a scientific and technological basic social public welfare undertaking, and meteorological research belongs to applied basic research. In the future, we will strive to improve the ability and level of refined global all-round and all-round meteorological services.

　　With the continuous development of economy and society, the planning of people’s activities is becoming more and more detailed, and the requirements for temporal and spatial accuracy and element accuracy of meteorological information are getting higher and higher; The scope of people’s activities is getting wider and wider, and the planning time is getting longer and longer, which requires as long as possible, all-round and all-round coverage of global forecasting services; There are more and more ways of people’s activities, and the demand for pertinence and personalization of meteorological information is getting higher and higher, and the demand for diversified information is increasing; The dependence and sensitivity of human survival on natural conditions and environment are getting stronger and stronger, and the task of meteorological disaster prevention and mitigation and coping with climate change is becoming increasingly arduous; People pay more attention to ecological civilization, green development and rational utilization of climate resources. Accurate and comprehensive meteorological service is the necessary guarantee for Socialism with Chinese characteristics’s modernization development.

　　In the next step, under the guidance of the spirit of the 19th National Congress of the Communist Party of China, the development of meteorological undertakings should face the needs of the new era, and strive to make the achievements of world scientific and technological development as useful as possible. Strive to improve the scientific and technological innovation ability based on data collection, processing and application, focusing on the development, application, evaluation and improvement of numerical models, and improving scientific cognition and innovative scientific methods; Strive to adapt to the high-tech transformation from qualitative to quantitative, from experience to science, from subjective to objective, from artificial to intelligent; Strive to build a meteorological team with scientific and technological talents as the main body. Meteorological work must strive to improve the service level of all-round climate assessment and meteorological forecast, and actively participate in and serve the overall development of national economic, political, social, cultural and ecological civilization construction to the maximum extent.

　　Accelerate the construction of a maritime power.

　　Deng xianming

　　In recent years, China has continuously strengthened the independent innovation capability of marine science and technology, strengthened the research and development of basic, forward-looking and key marine technologies, and made great efforts to improve the capabilities of marine exploration, research and application and the development and utilization of marine resources. The comprehensive strength of marine science and technology has been rapidly improved, from weak to strong, from following to leading, and some fields and pipe fittings technologies have even reached the world leading level. The innovation of marine science and technology has entered the stage of "qualitative breakthrough" in some fields. With the promulgation and implementation of the Law of People’s Republic of China (PRC) on the Exploration and Development of Deep Seabed Resources and the revised Law of the People’s Republic of China on the Protection of Marine Environment, China is steadily advancing towards the road of caring for, understanding and managing the ocean.

　　According to the report of the 19th National Congress of the Communist Party of China, the innovation-driven development strategy has been vigorously implemented, and the construction of an innovative country has achieved fruitful results. Major scientific and technological achievements such as Tiangong, Tianyan, Jiaolong, Mozi, Wukong and Big Aircraft have come out one after another. Among them, the major achievements of marine science and technology represented by the "Zhenlong" can be praised by the General Secretary, which shows the importance of marine science and technology to the construction of a strong country to a certain extent.

　　It is worth noting that the report of the 19th National Congress of the Communist Party of China clearly stated that the construction of a maritime power should be accelerated. This is inseparable from the accelerated emergence of a series of marine scientific and technological achievements in the past five years, such as "Xiaolong", "Hidden Dragon" and "Hailong". These outstanding achievements have laid a technical foundation for building a maritime power. However, although great progress has been made in the development of marine science and technology in China, and the overall scientific and technological strength is approaching that of developed countries, there is still a big gap in scientific and technological innovation ability and technology development. For example, there are few independent original innovations, especially in key areas such as deep sea and ocean, where the self-sufficiency rate of core technologies is low.

　　As a marine scientific researcher working in the front line, I believe that with the horn of accelerating the construction of a maritime power blowing, with the joint efforts of the vast number of marine scientific and technological workers, managers and related basic industries, guided by scientific and technological innovation, through hard work, China’s marine science and technology will certainly be at the forefront of the world, contributing to the construction of a maritime power and contributing to the realization of the Chinese dream of the great rejuvenation of the Chinese nation.

　　Ensure the safe supply of oil and gas resources

　　Zhang Gongcheng

　　The report of the 19th National Congress of the Communist Party of China pointed out that strengthening applied basic research, expanding the implementation of major national scientific and technological projects, and highlighting key common technologies, cutting-edge leading technologies, modern engineering technologies and subversive technological innovations will provide strong support for building a powerful country in science and technology, quality, space, network, transportation, digital China and smart society. This series of expositions points out the direction for the research of China’s oil and gas industry.

　　Oil and gas are the blood of industry. In recent years, with the rapid development of China’s economy, the demand for oil and gas has risen rapidly. Since it became a net importer of crude oil for the first time in 1993, the import volume has gradually increased, so the task of ensuring oil and gas self-sufficiency and stabilizing oil and gas supply has become more and more arduous.

　　China is rich in conventional oil and gas resources, but it is more and more difficult to find them. After nearly 70 years of large-scale exploration since the founding of New China in 1949, most of the easy-to-find oil and gas fields have been discovered, and the remaining exploration difficulties have gradually increased. Geographically, it develops from plain to plateau and polar regions, from shallow sea to deep sea and far sea, and from home to abroad; Exploration depth, from 3000 meters to 8000 meters or even 10000 meters deep and ultra-deep expansion; Underground conditions have changed from normal temperature and pressure strata to high temperature and high pressure strata and other complex and extremely complex fields; Formation conditions changed from high porosity and permeability reservoir to ultra-low porosity and permeability reservoir. This makes the theory and technology formed in decades face great challenges.

　　Based on the above situation, it is not difficult to see that to realize the long-term sustainable development of the upstream oil and gas industry, we must do a good job in basic research, strengthen basic research, regional research and comprehensive research, strive to innovate oil and gas geological theory, and constantly seek breakthroughs in exploration technology.

　　As the leading industry of the national economy, oil and gas is the basic guarantee for maintaining a stable supply of energy. The vast number of scientific and technological workers have the responsibility to actively implement the important instruction of "persisting in the overall planning of land and sea and speeding up the construction of a maritime power" put forward by the General Secretary of the Supreme Leader in the report of the 19th National Congress of the Communist Party of China, keep up with the world’s scientific and technological frontier, and strengthen the basic research of oil and gas exploration as the long-term development direction of oil and gas exploration, so as to ensure the safe supply of oil and gas and contribute the wisdom and strength of oil workers to the construction of the dream of a strong country.

　　Zeng Yu, deputy director of the Propaganda Department of Fuzhou Municipal Committee and director of the Information Office of the Municipal Government-

　　Ladies and gentlemen, friends from the press,

　　Good afternoon everyone! Today, we are here to hold a press conference on the prevention and control of COVID-19 epidemic in Fuzhou, to inform about the situation and answer questions from reporters.　

　　Present at the conference were: emergency headquarters, executive deputy commander of COVID-19 epidemic prevention and control work in Fuzhou, and Ms. Sun Xiaolan, deputy mayor of the Municipal People’s Government; Mr. Guo Yong, Director of Fuzhou Health and Health Commission; Mr. Dong Jingtai, Head of the People’s Government of Jin ‘an District. First of all, please invite Ms. Sun Xiaolan to brief us on the situation.

Sun Xiaolan

　　Sun Xiaolan, executive deputy commander of emergency headquarters and deputy mayor of the municipal government for the prevention and control of COVID-19 epidemic in Fuzhou-

　　Dear friends from the media:

　　Good afternoon everyone! Below, I would like to inform you about the epidemic prevention and control work in our city. There are two main aspects:

　　First, the basic situation of the case

　　As of 24: 00 on the 26th, Fuzhou had reported 186 asymptomatic infections and 5 confirmed cases, among which 63 cases were added that day. A total of 4,584 people were secretly contacted and 2,505 people were secretly contacted, all of which have been included in the control. There are 24 middle-risk zones in the city, including 17 in Jin ‘an, 5 in Minhou and 2 in Minqing.

　　II. Disposal of epidemic situation

　　In view of the current epidemic situation, the following work has been carried out:

　　1. Further strengthen social control. In order to quickly and effectively block the spread chain of the epidemic, starting from the 26th, the city suspended all gathering activities such as culture, entertainment, sports, folk customs, sales promotion, etc. When citizens enter supermarkets, pharmacies and other places, they need to hold a 48-hour negative nucleic acid certificate, and strictly implement normal prevention and control measures such as code scanning, temperature measurement and wearing masks.

　　2. Fully protect the rights and interests of candidates. On October 29th, the national qualification examination for primary and secondary school teachers in the second half of 2022 will be held. Nearly 50,000 people in our city will take part in this examination, which is a major event that concerns every candidate. According to the principle of "being able to take all the exams", we will accurately arrange the candidates’ code assignment, refine and improve the examination organization, and set up a special examination room for candidates with yellow codes to ensure the normal examination. Please pay close attention to the relevant reminder messages and official announcements, and take the exam for health.

　　3. Ensure people’s medical needs. In order to effectively protect residents’ demand for medical treatment during the epidemic, starting from 8: 00 on the 28th, we changed Jin ‘an District Hospital into a designated hospital for "red and yellow code" patients, providing medical services for "red and yellow code" patients in four urban areas, especially fever, tumor and pregnant women, and other counties (cities) also set up "red and yellow code" designated wards. In the next step, we will also provide medical services to citizens in high-risk areas by making rounds, providing on-site services and sending medical staff.

　　Citizens and friends, at present, we are at a critical moment in the race against the virus. In the next few days, I hope that everyone will consciously slow down the pace of life, calm down, not gather, not eat at home, and work at home. Now we are slowing down together to make this city get better faster. Thank you again for your understanding and cooperation. Thank you!

　　Zeng Yu:

　　I thank Ms. Sun Xiaolan for her briefing. Next, answer questions on the spot, please raise your hand before asking questions, and please report your identity after being invited. Now let’s start answering questions.

Fujian news broadcast reporter

　　Fujian News Radio reporter:

　　Recently, many citizens have reported that the health code has been given a "yellow code". Excuse me, under what circumstances will the health code be given a "yellow code"? How can citizens turn to green codes after being assigned yellow codes?

Guo Yong

　　Guo Yong, Director of Fuzhou Health and Health Commission:

　　Thank you for your questions.

　　In the epidemic prevention and control work, in order to beat the spread speed of the virus and gain precious time for the epidemic treatment, the staff will first assign "yellow codes" to the health codes of some people, including potential associates who have "time and space intersection" with positive infected people, mixed management personnel who are initially screened positive for regional nucleic acid testing, etc. This is an important health management measure for the epidemic prevention and control work in COVID-19, which can make the yellow code personnel reduce social activities, take the initiative to accept nucleic acid testing, and reduce the risk of epidemic spread.

　　Yellow coding is carried out by all levels and departments in accordance with the requirements of epidemic prevention and control, and the coding and transcoding of "Fujian Health Code" is managed and operated by the provincial platform. The related personnel screening is to obtain the owner information through the calculation of the mobile communication base station. Due to the large number of visits during this period, there will be a phenomenon of information transmission delay. Due to the need of epidemic prevention and control, there are certain restrictions on the "yellow code" personnel entering public places and taking public transport, and please understand.

　　If a citizen friend finds that his health code is yellow, please handle it according to the reason of "yellow code" prompted by the health code, and be sure to do the following:

　　1. Immediately report to the community and cooperate with the community investigation and management.

　　2. Wear a mask regularly, and go to the nearest "yellow code" nucleic acid sampling point for free nucleic acid detection as soon as possible (the information of yellow code and green code sampling points has been updated through "Fuzhou Health and Wellness" official website and WeChat WeChat official account).

　　3. Implement the "three-day two-test", that is, complete two nucleic acid tests within three days, and the interval between the two tests is not less than 24 hours.

　　After all the test results are negative, they can automatically turn into green codes.

　　At the same time that the health code is given yellow code, the city will send SMS reminders to the yellow code crowd. If the nucleic acid test has been carried out as required after being assigned the yellow code and the result is negative, it will be removed from the yellow code list; However, in the case of a large number of people with yellow code, there are cases where individual short messages are sent late and yellow code reminder short messages are received after turning to green code. The actual status is subject to the health code display. Remind citizens and friends in particular to pay attention to protecting personal information during the epidemic, and not to lend out identity documents, communication tools, electronic accounts, etc., so as not to affect the accuracy of coding.

　　Everyone is the first responsible person for his own health. The prevention and control of epidemic situation needs your joint efforts. Here, I also appeal to the general public and friends to understand and support the policies of epidemic situation prevention and control in a responsible attitude towards themselves, their families and friends, actively cooperate with nucleic acid detection, implement classified health management measures, and jointly win this war of prevention and control of epidemic situation. Your cooperation is our greatest support! Thank you all!

　　Zeng Yu:

　　Thank you! Please keep asking questions.

People’s Daily reporter

　　People’s Daily reporter:

　　In the past two days, the risk area in Jinan District is expanding. How to delimit and control the risk area and how to quickly block the risk of epidemic spread?

Dong Jingtai

　　Dong Jingtai, the head of Jinan District People’s Government:

　　Thank you for your question. I will answer this question. For the delineation and control of risk areas, we strictly follow the requirements of the ninth edition of the prevention and control plan of the State Council, scientifically judge, timely adjust and continuously optimize according to the trajectory of case activities and the risk of epidemic spread, combined with the guidance of provincial and municipal experts. At present, there are 17 medium-risk areas in our district, involving 41,500 people, and strict control measures such as "people don’t leave the area, taking things at the wrong peak" are implemented. At the same time, arrange district leaders to lead a team to form a special work class, and actively do a good job in life service guarantee and humanistic care in the risk area, so as to achieve strong control and temperature service.

　　In the face of the current epidemic situation, on the basis of doing a good job in the control and service guarantee of key populations in risk areas, we will further improve and implement various epidemic prevention measures, adhere to the principle of "quick word first, quick control, and fully block the risk of epidemic spread. Focus on three tasks:

　　The first is to improve rapid disposal. Further co-ordinate the multi-level forces of cities, districts, towns and streets, and join forces with health, disease control, public security, traffic police, urban management and other teams, and set up a special class of more than 400 people to ensure that key personnel can be locked immediately after receiving information about the epidemic, and quickly implement the work of chasing the sun, such as local control, door-to-door sampling, specimen inspection, detection and tracking, personnel transfer, isolation and disinfection, so as to find out the people involved in the epidemic as quickly as possible.

　　The second is to deepen comprehensive screening. At present, several rounds of regional nucleic acid detection have been carried out in our district. In view of the existing shortcomings, we timely improved measures, rationally optimized the yellow code and green code detection channels, increased on-site order guidance and maintenance, and urged the implementation of protective measures such as wearing masks and one-meter lines, and implemented various convenience service measures. For some people with mobility difficulties, we conducted door-to-door sampling, and for some citizens who failed to participate in nucleic acid detection in time, we accurately pushed SMS reminders to improve the coverage and efficiency of nucleic acid detection.

　　The third is to reduce social risks. In order to further effectively block the risk of epidemic spread, we have shut down hotels, restaurants, scenic spots, religious sites, cinemas, libraries, cultural centers, gymnasiums and other facilities within our jurisdiction, suspended gathering activities, and sent government officials to the front line to deepen the creation of "epidemic-free communities" and strengthen grid prevention and control at the grassroots level. At the same time, strictly implement various urban management control measures, guide the public to leave the banyan tree unnecessarily, and put an end to the risk of spillover.

　　I would like to take this opportunity to sincerely thank the general public and friends for their understanding, support and active cooperation in epidemic prevention and control, and work with us to resolutely win the epidemic prevention and control war and annihilation war! thank you

　　Zeng Yu:

　　That’s all for the on-site Q&A. Thank you for your questions and answers from the publishers. This afternoon’s press conference is over, thank you!

　　At 3: 19 pm on the 3rd, a fire broke out in the central air conditioning unit of the platform on the 6th floor of Longsheng Building, No.23 Hongwu Road, Qinhuai District, Nanjing, and the on-site open flame quickly burned to the 26th floor along the external wall of the 6th floor. The Nanjing Fire Command Center dispatched 17 fire engines and more than 150 police officers to the scene. In less than half an hour, the fire was extinguished and about 200 people were evacuated. No injuries were caused by the fire.

　　Yangzi Evening News reporter learned at the scene that Longsheng Building is a 28-story office building, and the platform on the 6th floor has an air conditioning unit, and a fire broke out due to a fault. Because of the strong wind that day, the fire shot up very quickly.

　　The investigation and handling of this fire accident is in progress.

　　Yangzi Evening News All-Media Reporter Ji Yuxuan Ren Guoyong

　　At first, the employees quickly saved themselves.

　　It’s useless to spray more than 20 cans of fire extinguishing agent, so we have to retreat

　　At 4 o’clock yesterday afternoon, the reporter of Yangzi Evening News rushed to the scene to see that a large number of police cars, fire command vehicles, large fire engines and ladder trucks were parked at Hongwu Road and Youfu West Street. The firemen are wearing breathing apparatus and are busy. A large number of evacuated employees are stranded around the building.

　　Mr. Bian of a company on the 8th floor of the building said that he was the first to find an open fire and took prompt measures. "I was sitting at my desk." Mr. Bian said that the fire happened to be just below his sight, so he found it at the first time. Mr. Bian said that at first he saw black smoke, and he didn’t care for the first few seconds. Later, he thought that a lot of black smoke must be on fire. So, he immediately called several other colleagues in the office. When everyone looked down, the fire had already burned.

　　"There are about 10 colleagues in the office." Mr. Bian said that they immediately went downstairs to find the property and explained the situation. Subsequently, more than 10 people and property staff came to the sixth floor together. "The fire has already started at this time. Fortunately, there are many of us." Mr. Bian said that everyone was holding fire extinguishers to put out the fire together, and all the fire extinguishers that could be transferred in the corridor were basically transferred. More than 20 cans of fire extinguishers were used, and the fire on the platform on the sixth floor was finally put out. However, the fire quickly moved to the outer wall and the office, and there was a door between the platform and the office area, which was always locked. At the critical moment, Mr. Bian and another colleague grabbed a fire extinguisher and slammed it at the door, finally breaking it open. Everyone found that there was a wooden floor in the office, and the fire was getting bigger and bigger, and the smoke was heavy and pungent, which was very choking. Subsequently, Mr. Bian can only temporarily withdraw from the fire with his colleagues.

　　On the steps at the entrance of Guotai Securities Building, a row of young men and women sat there. They are employees of a company on the 9th floor of Longsheng Building. "At that time, we went to work normally, and suddenly found a raging fire outside the south window. The fire was burning along the curtain wall, which was very scary. At the same time, someone shouted at the door of the company that there was a fire and evacuated." A female employee told reporters that dozens of people in their company were all evacuated to the ground through stairs in less than five minutes. "When there was a fire, all seven elevators were closed, and four of them led to the high area. Everyone was evacuated from the corridor, and the order was very good, so it was evacuated quickly." The female staff said.

　　Fortunately, the fire department arrived soon.

　　Soldiers split up and down in multiple ways, and the fire was quickly put out.

　　At the entrances and exits around the burning building, police and secret service personnel are on duty, and some areas are blocked with warning lines to prohibit irrelevant personnel from entering to avoid security threats.

　　A security guard told the reporter that the fire burned too fast this time. It only took about 3 minutes to burn from the 6th floor to the 26th floor. The tempered glass of the curtain wall kept falling, and the decorative plates around the curtain wall seemed to be flammable. Under the action of wind, it was impossible to save itself.

　　The reporter saw from Weibo, the official of Nanjing Fire Department, that Nanjing Fire Department mobilized two "water cannon trucks" to go to the scene to put out the fire. The anti-aircraft water cannon was erected on the downstairs of the building and sprayed water upwards. This water cannon can send the water column to an altitude of 60 meters.

　　The Yangzi Evening News reporter learned that another group of firefighters came to the top of Longsheng Building and sprayed water from top to bottom. In addition, the firefighters who entered the building put out the fire from the fire hydrant water pipe inside the building. At 3: 39 p.m., the fire was completely put out. Witnesses at the scene said that no one was injured and no ambulance appeared at the scene.

　　At the scene, a firefighter told reporters that the fire was located on the southwest side of the building, and there were many glass curtain walls on this side. "The wind is also very strong when there is a fire." He said that when the wind blows, the fire goes up. However, most of the external walls are glass curtain walls, and the glass can’t stand the burning of the fire and burst one after another. Subsequently, the fire ignited the attachments on the inside of the curtain wall, which gave people the feeling of burning a "1" shape.

　　The building is closed and the employees are in a hurry.

　　Oh dear! There are millions of cash in the office!

　　After the fire broke out and everyone was evacuated in an orderly manner, many company employees waited at the entrance and exit of the building. Two property workers guarded and prohibited them from entering.

　　"When will it open? I want to go up and get something!" "We want to go up and see what losses the company has!" At the door, many people asked anxiously. The property staff kept explaining that the fire is still being investigated and the hidden dangers have not been eliminated, so it is not possible to go in now.

　　A young man at the door said that his company has nearly one million cash in the office and is worried about safety. The reporter asked him, why did the company put so much cash? "Oh, I just brought it here today. When I was evacuated, there were still people in the company. Later, I don’t know what happened. I just reported it to my boss. The boss should let someone handle it." The young man said that he was still a little uneasy. Fortunately, the fire did not burn into the office area, but it was likely to be flooded.

　　In the parking lot on the downstairs side of Longsheng Building, many private cars were parked. After the fire broke out, the glass burst and fell from the upstairs, and many cars were damaged and broken by debris.

　　The reporter visited the inside of the building after the fire

　　The shower system can’t be turned off, and the office area becomes a shower room.

　　At about 5 pm, the building suddenly opened briefly, but it was only required to go up to the seventh floor. The reporter followed several employees to find out, there was no light in the corridor, and the water flowed along the stairs.

　　The corridor on the 6th floor was ankle deep, and the sound of rushing water was heard at the door of a company. The interior decoration of this company was a high-rise structure, with two floors, and the fire sprinkler system on the first floor was spraying water all the time, but it was still not closed. A notice was pasted on the glass at the door of the company, informing customers that the company had a holiday from the afternoon of April 30th to the 3rd during the May Day period, and went to work normally on the 4th. Therefore, when the fire broke out on the afternoon of the 3rd, the company was still on holiday, and no one was in the company.

　　After the fire broke out, the company sent a young man to the scene for disposal. The young man told the reporter that the boss was in the field, and he also came to see it temporarily. Now the company has been flooded, and he is eager to contact around, hoping to close the sprinkler system as soon as possible.

　　Later, the reporter came out of the building and found that the main entrances and exits were closed again, and they could only come out from the exit of the underground garage. The police were talking with the person in charge of the building property, asking him to arrange personnel to be on duty, only to be allowed to go out and not to enter, and at the same time asking the evacuated personnel stranded at the scene not to enter the building to prevent falling debris from high altitude.

　　pay close attention

　　The fire-fighting "Optimus Prime" also came and failed to show his skill.

　　The reporter found that among the fire engines on the scene, two ladder trucks were the most eye-catching, but one stopped at Huaihai Road and the other stopped at Hongwu Road, motionless. It is understood that the ladder truck, known as "Qingtian 101", is the highest ladder truck in Nanjing and the most advanced rescue vehicle. The ladder of the car can rise to 99 meters, and the maximum water spraying height can reach 150 meters. However, due to the lack of operating ground at the scene and the fact that the fire-fighting water cannon can completely achieve the goal, the ladder truck has never been able to show its skills.

　　When the fire burns

　　A rumor is also circulating.

　　Yesterday, when the fire broke out, the WeChat circle of friends spread a small video of "a black-faced policeman". Netizens said that this was a policeman who put out the fire on the spot, and his face was blackened. However, this is a rumor. These policemen are not from Nanjing at all, but the police on duty at the Mojiang activity site in Yunnan. During the activity, we "smeared each other’s faces" to celebrate the annual Hani Sun Festival.

　　Near the end of the year, a number of investment strategies of brokers in 2024 have been released one after another, making the latest judgments on macroeconomics, market trends and sector allocation in the new year. Institutions generally believe that the macro economy will continue to improve next year, and A shares are expected to usher in valuation repair. However, there are different views among brokers on the judgment of market style.

　　Macroeconomic recovery is expected to continue next year.

　　Looking forward to the economic situation next year, many institutions believe that with the continuous efforts of policies, the domestic macro-economy will continue to improve and market confidence will be boosted.

　　Huaan Securities predicts that the endogenous growth of the domestic economy will be around 4.6% in 2024, and with the help of policies, it is still expected to achieve a GDP growth rate of around 5% throughout the year. The supporting factors mainly come from two aspects: on the one hand, with the endogenous recovery of the economy, consumption gradually stabilizes, which constitutes the basic disk of growth; On the other hand, under the policy guarantee, the investment side continues to exert its strength. One is to issue additional government bonds to support infrastructure investment, and the other is to stabilize real estate investment in affordable housing in urban villages. At the same time, the recovery of exports has driven the manufacturing investment to remain stable.

　　Dong Qi, the macro chief analyst of Guotai Junan Research Institute, believes that it is expected that the economic growth rate will continue to recover in 2024, the rhythm will be high and then low, and the pattern of low inflation will continue. PPI will turn positive in the second quarter, exports will improve relatively, and consumption and investment will remain resilient.

　　According to CITIC Securities, the domestic macro-economy is expected to be steadily restored and its vitality will reappear in 2024. The vitality of domestic micro-subject economy will be restored with the weakening of the US dollar and the strengthening of policies, and the economy will gradually return to the potential medium and high-speed growth level. In 2024, the domestic GDP is expected to increase by 5.1%, which is structurally characterized by "old kinetic energy for stability and new kinetic energy for progress".

　　A shares are expected to usher in valuation repair

　　Since the beginning of this year, affected by multiple internal and external factors, the A-share market has fluctuated obviously. How will the A-share market be interpreted in the new year? Many institutions expect optimism.

　　Zhang Xia, chief analyst of China Merchants Securities Strategy, said that looking forward to next year, the revenue and profit growth of A-share listed companies is expected to maintain a slight upward trend. In terms of funds, the implementation of the previous capital market reform measures will effectively improve the supply and demand of funds, and it is expected that the incremental funds will turn to net inflows in 2024. With the end of the Fed’s interest rate hike cycle and the shift to interest rate cuts and table expansion, the liquidity of the US dollar is expected to improve significantly. It is expected that foreign capital will resume a small net inflow trend in 2024, which will have a positive impact on A shares.

　　"Overall, driven by the above factors, the A-share market will show a volatile upward trend, and the main broad-based index is expected to record a slight increase." Zhang Xia said.

　　Zheshang Securities believes that the state of China’s economic operation is a key factor for the judgment of the general trend in 2024. With the help of the auxiliary description of inventory cycle, combined with the forecast of investment, export and consumption, it is predicted that A shares will show a trend of shock recovery in 2024.

　　CITIC Securities predicts that, from the rhythm point of view, the A-share repair will be more flexible in the first half of 2024, and may fluctuate and differentiate in the second half. It is expected that the New Year’s Eve to the first quarter of next year will be an obvious window to boost market confidence, and the slope of A-share repair will be the largest. With the verification of domestic economic targets and the slope of restoration, the reform of the investment side of the capital market continues to take effect, and the market is expected to continue to repair in the second quarter of next year, and the slope tends to be flat. It is expected that the market structure may begin to differentiate after the A-share valuation has undergone three stages of repair in the second half of next year.

　　What investment opportunities are worthy of attention?

　　Since the beginning of this year, the rotation of A-share theme has been accelerated, and the configuration is more difficult. Which investment direction is worth paying attention to next year, the dominant value style or the dominant growth strategy? In terms of style judgment, brokers have their own opinions, but the pre-judgment growth style is dominant.

　　Caitong Securities believes that the A-share market style is expected to be relatively balanced next year, and the valuation is expected to pick up. It is recommended to pay attention to the Science and Technology 100 Index and the Entrepreneurship 200 Index. Judging from the comparison with the historical bottom area and the characteristics of institutional heavyweights, many indicators of current A shares are at the bottom. Consumption, TMT and many other segments are cost-effective, and next year’s profit and valuation are expected to be Shuang Sheng, and the market is expected to warm up. Combined with multiple factors such as profit margin improvement and policy drive, the growth style of A shares may be relatively dominant next year.

　　Zhang Xia is also optimistic about the performance of growth style next year. He said that under the trend of bottoming out of profits and declining yield of US bonds, A shares may turn to growth style. From the perspective of industry, it is suggested to pay attention to science and technology, medicine and some cyclical stocks, and pay attention to the new energy sector after the second quarter, based on the comprehensive judgment of macro environment, science and technology cycle, supply and demand pattern of production capacity, changes in core driving factors of industry prosperity and market performance in the past two years.

　　Huaan Securities judges that the growth of the A-share market and the market of the consumer sector will alternate next year. Growing the main line of science and technology or leading the annual market, the main line of consumption is expected to follow closely. When the overall growth style is dominant, industries such as electronics and communications are preferred. With the stabilization of the real estate industry and the significant upward consumption of services, the consumption style is expected to gradually dominate.

　　Fang Yi, chief strategist of Guotai Junan Research Institute, believes that the small-cap theme market may cool down in the first half of next year, and the stable style of the large-cap market is expected to prevail. Since the beginning of this year, investors’ risk appetite has tended to be at both ends: small-cap growth stocks have risen, while large-cap blue-chip stocks have fallen. It is expected that the market of small-cap theme stocks with high-risk characteristics may ebb in the next stage, and investment opportunities may turn to large-cap stocks with low-risk characteristics. It is suggested to pay attention to investment opportunities of fixed-income bonds and related products.

On September 6th, according to the previous statement of Tesla CEO Elon Musk, the company has recently officially raised the price of the fully automatic driving (FSD) package of the advanced driver assistance system to 15,000 US dollars (about 103,900 yuan).

According to foreign media reports, some people believe that this FSD system is not worth $15,000 at present. ; Although it costs $9,000 more than the enhanced version of Autopilot, users only have the opportunity to experience the latest beta version of FSD.

Over the years, Musk has always said that with the continuous improvement of the functions of the FSD system, the car will eventually be fully autonomous. Tesla will also gradually increase the price of this system.

. Although the test has been carried out for two years, there is still a long way to go to realize the full automatic driving of the car.

From a technical point of view, the FSD system can run in most traffic environments, including crossing intersections, but the responsibility for driving still lies with the driver, who still needs to keep his attention and be ready to take over control at any time. The industry believes that the most important step for companies developing autonomous driving systems to achieve this goal is to be willing to assume the driving responsibility under the activation of the system.

Tesla has made it clear that this cannot be done. The company sent a series of warnings to users who participated in the FSD Beta test, clearly indicating that the driving responsibility still lies with the driver.

Tesla believes that every update of the FSD system means a step closer to the goal of fully autonomous driving, and that some of these updates are worthy of raising the overall price of the system.

Last month, Musk also reported that Tesla would increase the system price from $12,000 to $15,000 as the company launched the beta version of FSD Beta 10.69 on a larger scale.

On Monday, Tesla updated the price information of FSD on the vehicle customization page in official website-by $3,000-but did not include more new features. There are more words such as "coming online" and "automatic turning on urban roads" in the description of the page, which is still in the testing stage open to invited users, and it is not much different from the previous routine update.

If the user already owns Tesla’s enhanced Autopilot system, there is nothing new except the opportunity to experience the latest beta FSD, and the test experience itself is not a reward.

Musk has made it clear that the value of a fully autonomous driving system far exceeds $15,000. He said that the price would continue to rise. In fact, the initial price of the FSD system was only $6,000. Now, what you buy with an extra $9,000 is not what users really want, but that you can bet on Tesla to provide real automatic driving function in the future, and you can start at a lower price.

However, it is not clear how Tesla can develop the beta FSD into a safe autopilot system that is willing to take responsibility.

　　As the countdown to the Spring Festival begins, do you intend to treat yourself and your family well by unloading the hard work and fatigue of the year? However, sugar friends pay attention, long holidays often break our daily habits and rhythm of work and rest. Short-term lifestyle changes have little impact on normal people, but it is still a big impact on sugar friends. Don’t just have fun secretly, come and think about what to do with blood sugar.

　　Du Ruiqin, director of the Department of Endocrinology, Rheumatology and Immunology of the Rocket Army Special Medical Center, gave sugar friends "3 sentences, 5 numbers".

　　3 sentences: Keep your mouth shut, open your legs and be regular.

　　5 figures: guarantee 1 bag of milk every day; Intake 200-250g carbohydrate every day; Ensure 3 servings of high-quality protein every day (1 serving of high-quality protein = 1 serving of pork = 2 serving of fish = 1 serving of egg); Keep in mind four sentences every day: the food is coarse and fine, not sweet or salty, eat less and eat more, and be seven or eight points full; Ensure 500g vegetables every day.

　　Let’s talk about the topic of shut up first:

　　Keep your mouth shut: eat reasonably and avoid "excess". During the Spring Festival, you can appropriately relax eating boiled vegetables and cold dishes; Cooking, fish, shrimp, lean meat, etc. can also be eaten properly, but friends with kidney disease and gout should be treated with caution; Sugar friends should also pay attention to the speed of eating, and chew at least 20 times for each bite of rice; To control alcohol addiction, if you really want to drink, you should choose white wine or dry red wine with low sugar content, or you can drink some beer, and it is best not to choose white wine; Resist the temptation of snacks.

　　Spread your legs: When friends and relatives get together, they often sit around a table in Kan Kan and talk. In fact, the chat can also be changed to after dinner (one hour after the first bite of the meal), and we can have outdoor activities together, and we can also talk while walking. If the environment does not allow, you can also choose to stay at home, do exercises, reduce blood sugar, and have heart-to-heart talks. What a happy thing.

　　Regularity: Vigilance is a traditional custom in Chinese. On this day of national celebration, sugar friends can also relax appropriately. After all, it is not easy to "control sugar" hard for a year, but it is necessary to grasp the degree of relaxation. We can go to bed late and get up late occasionally, but we can’t reverse day and night; Monitoring blood sugar should be regular: measure one if you are unwell, one after eating and drinking, one after staying up late, keep abreast of your physical condition, eat on time and live regularly.

　　Finally, tell sugar friends a small coup: when eating, choose a medium-sized disc, with a little for each dish and a little for the staple food, and you will find that you can also fill a plate. The food in this plate is the amount of food you eat this meal. You must be able to do this, right? Looking forward to your answer.
