　　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.

　　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.

　　CCTV News:Recently, the Protection Administration of Old Town of Lijiang, Yunnan Province issued the Interim Measures for the Administration of Access and Exit of Market Operation Projects in Dayan Ancient City of Lijiang, which came into effect on April 1, 2019 and was valid until March 31, 2022. The method clarifies the Negative List of Business Projects in Old Town of Lijiang, which is divided into two categories: restricted access category and prohibited access category (timely adjustment).

　　There are seven categories of restricted access projects that are not allowed to operate, including catering, tambourines, bars, jewelry, jade, jade, beeswax, amber, farmers’ markets, tea bars, cosmetics and so on. Prohibited access categories include open-flame barbecue, dance halls, Internet cafes, digital products, sauna massage, beauty salons, modern clothing sales and other 16 categories.

　　CCTV reporter learned from Old Town of Lijiang Protection Administration that the business projects discouraged in the measures will be strictly controlled and will not be approved in principle. Operators who have already obtained the Access Certificate for World Cultural Heritage Old Town of Lijiang Business Projects or the Permit for Old Town of Lijiang Business in Scenic Areas will gradually reduce their scale and quantity according to regulations, and gradually guide them to switch to business. For the business projects prohibited in the measures, if they have existed before the implementation of these measures but have not been transferred to the business in time, the ancient city protection and management institutions and relevant industry departments will jointly guide them to transfer to the business or withdraw from the business in the ancient city.

　　The measures also pointed out that operators engaged in business activities in the area of Dayan Ancient City in Lijiang are strictly prohibited from taking unfair means to compete for tourists and soliciting customers, slaughtering customers, bullying customers and other illegal acts that disrupt the tourism order and business order of the ancient city. In addition, this method also clarifies the decoration style of business premises in the ancient city, including that the pattern and style of shops must follow the basic form of traditional commercial shops in Old Town of Lijiang, and the traditional architectural style must not be destroyed when the original dwellings are repaired.

　　The market rumors of Pfizer COVID-19’s oral medicine imitation license have been confirmed.

　　On March 17th, official website, a pharmaceutical patent pool (MPP), announced that it had signed agreements with 35 companies, which were allowed to copy and produce nirmatrelvir, one of the ingredients of Paxlovid, an oral drug of Pfizer COVID-19.

　　According to the map released by official website, the countries involved in the agreement are distributed in 12 countries around the world, among which 6 companies will focus on the production of APIs, 9 companies will produce drugs, and the remaining 20 companies will have both. There are five pharmaceutical companies in China, including Huahai Pharmaceutical (600521), Puluo Pharmaceutical (000739), Fosun Pharmaceutical (600196), Jiuzhou Pharmaceutical (603456) and Shanghai Disino, among which Jiuzhou Pharmaceutical only produces APIs, while others can produce APIs and preparations at the same time.

　　It is worth noting that the agreement will help to expand the accessibility of Pfizer COVID-19 oral medicine in 95 low-and middle-income countries, accounting for about 53% of the world population, but excluding China.

　　Earlier on March 17, the above news was circulated in the market, and the above listed companies once had a daily limit. Previously, it was rumored in the market that Puluo Pharmaceutical could only produce APIs. According to the newly published map, Puluo Pharmaceutical can produce both raw materials and preparations.

　　It is worth noting that a Ukrainian company is also on the list of 35 companies. MPP said that due to the current conflict, it could not be signed, but the license could still be used.

　　According to the data of official website, the Pharmaceutical Patent Pool Organization is a public health organization supported by the United Nations, which is committed to increasing access to life-saving drugs for low-and middle-income countries and promoting drug development.

　　On January 20th, local time, the Pharmaceutical Patent Pool Organization (MPP) announced through official website that it had signed an agreement with 27 pharmaceutical companies to allow them to produce and supply the oral anti-Covid-19 drug Molnupiravir of Merck to 105 low-and middle-income countries or regions around the world, so as to promote the affordability and accessibility of the drug in the world. Five China pharmaceutical companies, such as Fosun Pharma, Borui Pharma, Shijiazhuang Long Ze Pharmaceuticals, Shanghai Diseno and Langhua Pharmaceuticals, are among them, of which the first four are allowed to produce both raw materials and finished products, and Langhua Pharmaceuticals is allowed to produce raw materials.

　　In other words, two pharmaceutical companies, Fosun Pharma and Shanghai Disino, have obtained the rights to prevent and control the production of Pfizer and Merck.

　　Pfizer’s Paxlovid is a combination of PF-07321332 and ritonavir, which has been approved for conditional marketing in China. Molnupiravir of Merck is a nucleoside drug in oral form, which has not been approved in China.

　　In order to speed up the application of large-scale models and continuously promote the commercialization and large-scale popularization of typical applications, on the basis of summing up and evaluating the work experience of the first and second batch of partner programs, the third batch of "partner program" members is now organized, focusing on "high-quality data supply, high-performance computing power supply and high-value model application", and the partner members in five fields of computing power, data, model, application and investment are widely collected. The relevant matters are notified as follows.

　　I. Scope of the "Partnership Program"

　　The "Partnership Program" aims to build a market-oriented service platform with industrial synergy, complementary advantages and resources, effective application and flexible cooperation mechanism among partners.

　　(1) Calculation partners. Widely collected throughout the country, especially in Beijing, Tianjin, Hebei, Mongolia and surrounding areas. Computing partners have the ability to provide diversified and high-quality computing resources, and can give priority to providing high-quality computing services to large model teams and enterprises in this city, which can effectively reduce the threshold for computing use of small and medium-sized enterprises and individual developers, and can access the computing interconnection and operation service platform in Beijing. Computing partners should have cooperation cases with large model enterprises and AIGC enterprises in high-performance computing support. Encourage enterprises with domestic computing resources to actively participate.

　　(2) Data partners. Data partner is the main body of data factor market, including data provider and data trader. Aiming at the high-quality data required for large-scale model training, it can combine specific application scenarios, give full play to the advantages of massive data resources and professional advantages of data providers, and realize the effective supply of training data and the compliant, efficient, safe and orderly flow. Priority should be given to the fact that the relevant data resources of data providers can be physically migrated, relying on the pioneer area of Beijing data basic system and the National Artificial Intelligence Data Training Base, and provide data support for large-scale model training through platform transactions. Encourage enterprises that can provide high-quality data resources for practical application scenarios such as intelligent manufacturing, government affairs, finance, medical care, entertainment and education to actively participate.

　　(3) Model partners. Model partners mainly include general model enterprises, industry model enterprises and model service providers. The technical parameters of the general large model need to reach the domestic leading level, and the development of industry models based on the general large model is encouraged. Model partners should have the ability to provide application services by using large models, and can provide application services based on specific industries, or rely on the basic model platform to train and optimize through exclusive industry data to provide industry application services. Related model services or applications have achieved commercial cooperation or large-scale promotion and use.

　　(4) Application partners. Application partners refer to all kinds of industry users who apply large-scale model capabilities to support business development. They should have a clear demand for cooperation in open scenarios, and have the ability and willingness to cooperate with applications. They can open their own typical application scenarios and rely on model products and services to drive business to improve quality and efficiency. Encourage central enterprises, state-owned enterprises and other units to actively participate.

　　(5) Investment partners. Investment partners can empower the development of general artificial intelligence industry by means of capital assistance and service docking, and play the role of incubation, guidance and driving. They should have the sustainability of investment and services, provide a good environment for investment, incubation and cooperation docking, and regularly hold docking exchanges, salons roadshows and other activities to drive scientific and technological innovation, discover typical scenarios, promote cooperation, and promote the high-quality development of the digital economy. In the past two years, the number of investment projects in large models and related industries of investment partners has reached more than 5; Investment partners organize at least 10 roadshows and other service docking activities every year.

　　Second, the reporting conditions

　　(1) reporting conditions. Units that are willing to participate in the development of general artificial intelligence industry in Beijing and meet the relevant conditions of five types of partners. There is no bad record in terms of quality, safety, reputation and social responsibility.

　　(2) Relevant rights and interests. Enjoy the docking service of computing power, data and application among partners, and provide relevant policy publicity and guidance.

　　Third, the working mechanism

　　In order to fully reflect the service docking effect of the "Partner Program", mobilize the enthusiasm of partner members and promote the double improvement of cooperation quality and effect, the working mechanism of partner member units is specially formulated.

　　The member units that have been selected into the partnership plan should actively participate in relevant activities or meetings and perform their partnership duties. After comprehensive evaluation, the member units that do not participate in relevant activities without reason will take measures such as "reminding and revoking partner membership" respectively. All partner memberships are reviewed quarterly, and enterprises and institutions that fail to reflect the role of partner members will be led out after a quarter of observation. All partner member units shall strictly abide by the objective facts in providing capacity services and information disclosure, and shall not slander their peers. The materials and documents shared or disclosed shall comply with relevant laws and regulations, and bear relevant responsibilities caused by self-behavior.

　　Fourth, the declaration method

　　The reporting entity can choose to assume one or more partner roles according to its own business type. The applicant should fill in the Application Form for the Third Batch of Beijing "Partnership Program" (see the attachment for details), and send the official application form PDF document and Word document to the contact email before March 1, 2024.

　　(Contact: Zou Qifeng, Wang Wei and Li Yiming; Tel: 18730662199 13810101764 13910808181; E-mail: gaozhengzhou@jxj.beijing.gov.cn)

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)

　 　 Special feature of 1905 film network After that, Xu Haofeng was spread more and more. The media is eager for legend, and peers are looking forward to performance. In addition to the common names such as writer, director and martial arts instructor, rumors have claimed that this college teacher has become the head of a certain sect. However, just as he and the famous "academic" directors in recent years can’t be easily classified into the ranks of China directors divided by generations, Xu Haofeng and his films can’t simply be classified as traditional martial arts films. This made Xu Haofeng embark on a completely different road from the previous martial arts movies since he made his debut in 2012. And to this part, not only is the master passing by, but you can almost see the entrance of the school.

　 　 Record companies always advertise newcomers with the banner that "no one has ever sung like him". This sentence can also be used in Xu Haofeng’s name: no one has ever made a martial arts movie like him. It is precisely his strength and fortune to break the wind direction led by Hong Kong for a long time. Nowadays, the brand of the new school of martial arts can definitely afford to make movies by taking moves from oral instruction.

　 　 The film has been in China for 110 years, and the martial arts film has a history of 87 years. Since the first martial arts film, most chivalrous swordsmen wear Peking Opera bunt and follow the routine of Wusheng peking opera blues. What did the ancients wear? It was not until two great directors, Li Hanxiang and Hu Jinquan, that the film circle became addicted to textual research, and gradually took off their costumes and embarked on the road of life. However, the improvement of martial arts drama is not so easy, and Hong Kong people carry forward the title of "martial arts director" to shoot action scenes instead of directors.

　 　 Although there is no martial arts in the Hong Kong martial arts circle, Liu Jialiang, the famous director, is a direct descendant of Hongquan. However, the mainstream still belongs to Cheng Xiaodong and Yuan Heping, who have a background in Peking Opera, and Jackie Chan and Sammo Hung, members of the "Seven Little Happiness" from the troupe. These martial arts refers to the "monopoly" of Hong Kong martial arts films, which makes the action scenes more and more dazzling, in order to highly purify the word entertainment. It made the martial arts films develop into the 90′ s full of gods and buddhas. The action styles they created also spread from Hong Kong to Greater China and even Hollywood. After the new millennium, Zhang Yimou is still the remnant of Xiangjiang River, which is a trick and a half, and all of them eat the old money accumulated over the years. This year, Chen Kaige remake a novel from Xu Haofeng, and the martial arts instructor still invited Ku Huen Chiu from Yuan Jiaban, playing the same trick as Stephen Chow 10 years ago. Therefore, the appearance of Xu Haofeng and his films is just to get rid of the action design of Hong Kong martial arts films and return kung fu to Wulin. This year’s Golden Horse Best Action Design Award of Master is absolutely justified.

　 　 In Master, Liao Fan, the hero, played Wing Chun. In the Republic of China, Tianjin was mixed with foreign countries, and the kinds of boxing flourished; Wing Chun is just a small boxing in the north, and there are a lot of local sects in Tianjin in the story. Xu Haofeng is a practitioner. Although he has never played Wing Chun, his cooperation with Wong Kar-wai has made him know many Wing Chun masters. The rest of the boxing and even the sword and halberd have the director’s own textual research results for many years. With this foundation, "Master" can be described as full of confidence. In addition to fists and fists, weapons are another highlight in Master. In the street fighting at the end of the film, Liao Fan held an eight-blade wing chun weapon, and all the tricks and styles he made were also verified by Xu Haofeng from the previous generation. Xu Haofeng didn’t design any fancy and unpractical lens, but Liao Fan’s intention in the movie was to preach the knife method, which sounded like what Xu Haofeng himself wanted to say to you: I showed all my moves, and how much I took depends on the individual.

　 　 The implication of dialogue is another feature of Xu Haofeng. With his participation, the script of "A Generation of Masters" was once eloquent. The words in "Master" are divided into three parts, which is the same as the rhythm of the film, and it is also integrated with the style of Xu Haofeng’s novels. The film relies on the original work, so it is extremely literary. In the first half of the film, Master Chen Shi, played by Liao Fan, got acquainted with Tianjin Wuxingtou brand, and Zheng Shanao, played by Jin Shijie, was intended to make a name for himself. Although Zheng Shanao fully assisted, he also intended to use Chen Zhifeng to retire. After the relationship between this group of characters is abstract, it is the template of the so-called borrowing people to ascend to heaven and becomes a skeleton in the literary sense. Filled with flesh and blood, it is only in the moments when the director is most ruthless that the wound is torn open, so that you can see what the bones and muscles that support the flesh look like. From this perspective, the martial arts action scene is only the first layer of the film, and it is also the most eye-catching commercial element; The helpless sigh for the lost years is the second obvious layer, while the core refers to the interaction between people in any society. The inherent richness and ambiguity of the film also makes Master surpass the previous martial arts films and appear more authentically.

　 　 In addition to the literary significance of Master, Xu Haofeng still wants to make sense out of things, saying "rules", the two most beautiful words in the film. In Zheng Shanao’s mouth, the rules were established by ancestors and handed down by the people; In the eyes of curator Zou, played by Jiang Wenli, rules are just the game of those in power. The confrontation between these two logics is precisely the confrontation between the old and the new in this era of the Republic of China. Fame in World War I is only the plot in the story. From the first movie, Xu Haofeng tried to put the truth he believed in into the characters. However, this only created a thousand people’s side in The Trail of the Enemy. It was not until this "Master" that martial arts became successful, with the times as the skin and the characters as the bones.

　 　 Therefore, Master, as a martial arts film, is unique in two aspects, one is the innovation of action design, and the other is the significance of martial arts film as a genre film. These two layers coexist and grow together, and they are both inside and outside each other. In the film reviews he once wrote, Xu Haofeng himself wrote that the fear of certain things supports a genre film, while the martial arts film should be the fear of modern guns. Xu Haofeng abandoned Weiya and body double and told such a story in the Republic of China, which was precisely the practice of his own theory.

　 　 In the film, Liao Fan uploads his fist to the north alone, comes from nowhere, and leaves with an unknown surname, leaving only the street legends of his disciples who fought in eight martial arts schools in Tianjin. In reality, Xu Haofeng’s "Master" is actually a real northern fist going south, and the ability to settle down has been revealed, which won the Golden Horse Award. However, for Xu Haofeng, it is still famous and has not yet been established. To be a great master, it is necessary to shine a light on future generations. Therefore, people can’t help but expect that Xu Haofeng’s skill will eventually be learned by what kind of latecomers.

　　(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. However, due to the upgrade of technology and performance, the initial sales price of the new generation products is higher than that of the previous generation. Therefore, in the case of continuous iteration, the average sales price of products will remain stable and upward.

　　Q: What is the competition pattern between DDR5 memory interface chip and memory module supporting chip?

　　A: At present, the competition pattern of DDR5 memory interface chips is similar to DDR4 memory interface chips. Only three suppliers in the world can provide the first generation of mass production products, namely, the company, Renesas Electronics and Rambus, and the company’s market share in memory interface chips remains stable. On the supporting chips, the two main suppliers of SPD and TS are Lanqi and Renesas Electronics. PMIC has more competitors, and the competition will be more complicated in the initial stage.

　　Q: What is the reason for the decline in the revenue of interconnected chips in the first quarter of 2022?

　　A: The company’s revenue of interconnected chips decreased slightly in the first quarter of 2022, mainly due to: 1. Quarterly fluctuations. In normal years, the first quarter is off-season compared with the fourth quarter; 2. Due to the special period disturbance, the logistics efficiency of some products was affected by the static management in Shanghai and its surrounding areas in late March, and the shipment was postponed to April. After active coordination, the current logistics efficiency has basically returned to normal.

　　Q: Why did the gross profit margin of interconnected chips decrease in the first quarter of 2022?

　　A: In the first quarter of 2022, the gross profit margin of interconnected chips decreased slightly from the previous quarter, mainly because: DDR5 memory module supporting chips were jointly developed by the company and its partners, and the gross profit margin was lower than that of memory interface chips. With the increase of its revenue share, the average gross profit margin of interconnected chip product lines declined.

　　Q: Does the company have room to improve the future market space of CPU business? What are the direct customers and downstream applications of this business?

　　A: In view of Tianjin CPU, because the market space is very large, the company’s primary goal in the initial stage of products is to pursue quantity, enter the market as soon as possible, strive for more market share and gain more customers’ recognition. Because of the large value of this product, once it is on the market, the absolute amount of gross profit will be considerable. At the same time, after accumulating a certain number of customers and reaching a certain income scale, the company will develop new functions to enhance the added value of products in combination with the needs of customers, and actively optimize costs, thus ultimately improving the gross profit margin of this product line.

　　China’s server market maintained a high-speed growth trend. According to IDC’s research report, in 2021, the shipment and sales of China’s server market were 3.911 million units and 25.09 billion US dollars, respectively, up by 8.4% and 12.7% year-on-year. The introduction of strategies such as "Digital China" and "Counting East and Computing West" is expected to bring great impetus to the development of China server market in the next few years. At the same time, with the continuous strengthening of the competitive strength of domestic brands, domestic brands’ server-related products will enjoy more growth dividends in China server market.

　　In 2021, the sales volume of related products of Tianjin Capture Server Platform exceeded 150,000 pieces. If a server is equipped with two CPUs on average, the market share of related products of the company will be about 2% in 2021, which has great market expansion potential.

　　The direct customers of the company’s CPU are mainly OEM or ODM manufacturers of servers, and the larger downstream applications are finance, transportation, government affairs, energy, data centers and other fields.

　　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. The specific new product layout strategy will be gradually developed in combination with the company’s technical advantages or market advantages.
