　　海外网6月13日电美联社11日报道称，弗洛伊德之死引发的抗议示威活动中，美国加利福尼亚州共部署8000名国民警卫队士兵协助地方警察，为此需要支付近2500万美元。

　　据报道，这笔钱中超过1800万美元花在了洛杉矶县，国民警卫队在这里部署了5500名士兵来保护建筑和其他基础设施。剩下的钱则用于在包括旧金山和萨克拉门托等城市部署军力。

　　加州州长纽森此前宣布洛杉矶县进入紧急状态，这样该州就可以通过从专门用于救灾的账户中提取资金，支付洛杉矶县花费的1800万元。加州财政部门11日致信州议员，称部署军力是有必要的，以减轻洛杉矶地区的治安压力。

　　加州军事部门要求将其余的钱以“紧急开支”的名义支付。“紧急开支”定义为应对灾害或极端危险的情况，这些情况会直接威胁到该州民众健康或财产安全。

　　然而，反警察恐怖项目联合创始人凯特·布鲁克斯认为，这是浪费大量资金，这些钱完全可以用于学校教育、心理健康、病毒检测和医疗保健等领域。加州陆军国民警卫队上校克雷格 桑德曼在一份备忘录中提醒称，如果政府不提供资助，加州军部的资金将会耗尽。（海外网 张琪）

　　Xinhua News Agency, Wuhan, May 13th: From focusing on water quality to focusing on water ecology — — The Yangtze River "big physical examination" hits directly

　　Xinhua News Agency reporter Li Siyuan

　　"This is a lake area, and there is a risk of contracting schistosomiasis. Don’t touch the water with your arms." At 2 o’clock on the afternoon of May 13th, in Dongting Lake, the middle reaches of the Yangtze River, under the reminder of colleagues, Han Tangrui, a post-90s monitor, pulled up the mud collector from the bottom of the water with his body close to the boathouse. The weight of 40 or 50 kilograms of mud collector and sediment made his face red.

　　Han Tangrui comes from the Ecological Environment Monitoring and Scientific Research Center of the Yangtze River Basin Ecological Environment Supervision Administration of the Ministry of Ecology and Environment, and is also a staff member of the pilot monitoring of water ecological assessment in the Yangtze River Basin in the spring of 2023.

　　In April this year, under the leadership of the Ministry of Ecology and Environment, the pilot monitoring of water ecological assessment in the Yangtze River Basin was launched in the spring of 2023. Monitoring personnel from the Yangtze River Basin Ecological Environment Supervision Administration and other units will comprehensively monitor the water ecology of 331 points in the main stream, key tributaries and key lakes and reservoirs of the Yangtze River from Qinghai to Shanghai within two months to find out the water ecological base of the Yangtze River and make a "big physical examination" for the mother river of the Yangtze River.

　　According to the job requirements, the main task of Han Tangrui and his colleagues is to collect samples of macrobenthic invertebrates and zooplankton. "These creatures are important indicators of the health of water ecology. Macrobenthic invertebrates, although called ‘ Large ’ In fact, they are not big, some species are only a few millimeters in size, but they are very sensitive to changes in environmental conditions such as hydrology, water quality and climate, and are called ‘ Underwater sentry ’ 。” Han Tangrui introduced.

　　In recent years, with the continuous promotion of the great protection of the Yangtze River, the ecological environment protection in the Yangtze River Economic Belt has undergone a turning point, and the ecological environment quality has been continuously improved. "The water quality is constantly improving, and the proportion of water quality section of Grade III exceeds 98%, which means that it is necessary to improve the health of the Yangtze River ‘ Portrait ’ In addition to using traditional physical and chemical indicators of water quality, we have to rely on higher-level water ecological monitoring. " Xu Yi, director of the Yangtze River Basin Ecological Environment Supervision Administration, said that China plans to take the lead in establishing a water ecological assessment mechanism in the Yangtze River Basin, and to establish this mechanism, it is necessary to conduct a comprehensive "physical examination" of the Yangtze River.

　　According to reports, in order to more accurately grasp the water ecological status of the Yangtze River and lay the foundation for the water ecological assessment of the Yangtze River Basin, this year, the Yangtze River Basin Ecological Environment Supervision Administration added two indicators, namely river epiphytic algae and lake phytoplankton, to enrich the monitoring dimension.

　　Xu Wei said that from focusing on water quality in the past to focusing on water ecological changes now, carrying out water ecological monitoring as the "big physical examination" of the Yangtze River is itself progress and innovation, which indicates that the main task of ecological environmental protection in the Yangtze River has shifted from water pollution prevention to equal emphasis on water ecological environmental protection and restoration.

　　[PConline evaluation]Recently, the graphics card industry is full of news about GTX780, which is fascinating, but it is not something that ordinary users can consider. Let’s look back at the actual products. A series of old graphics card tests, we have been reflected by many netizens, this time we should test GTS250 at the request of netizens.

　　The graphics card is called "GTS250", and familiar netizens know that this is the "mysterious" power of NVIDIA, which has changed from 9800GTX+. The specifications and parameters are just like 9800GTX+, and there is a significant change in memory. At that time, the core of NVIDIA G92 was old.

　　After years of baptism, the high-end old cards many years ago are no different from the performance of general mainstream graphics cards. This time, we use another test method to see the performance differences of GTS250, GTS450 and GTX650. These three graphics cards use three different architectures and three different technologies, which also represent three different eras.

Comparison of three products with "5":

　　Although it also had a "5", GTS250 was launched in the mid-to high-end market of 999 yuan at that time, pushing HD4850. Similarly, GTS450 is also used as the mid-end market of 899 yuan, and HD6770/6750 is suppressed within 1,000 yuan. By GTX650, the market it faces has become the mainstream level, and this "5" has been devalued more and more.

　　GTS250 uses the "G92" core which has entered dusk at that time (it has been used for three generations). Although the technology is a little old, its performance is still a bit worth seeing. When it comes to GTS450, using the mature Fermi architecture, the most brilliant period is not that it can suppress HD6750, but that the GTX650 introduced later is expensive, which makes GTS450 have a short spring. GTX650 is currently using NVIDIA’s most advanced Kepler architecture, with excellent energy consumption ratio, but the price is still slightly higher.

　　If you want to know the positioning of the graphics card at that time, then it is most direct to look at the memory width. Due to the high cost of GDDR5 at that time, GTS250 still used GDDR3 video memory, with 256bit width and 64 texture units, which could not hide its high positioning at that time. As for the current GTX650, except for more stream processors, other parameters are relatively simple.

　　This time, we received three graphics cards from Mingxin, which were used to test the performance and power consumption differences of these three graphics cards: GTS250, GTS450 and GTX650. These three graphics cards use the three-generation architecture of Trass, Fermi and Kepler respectively, and the three processes of 65 nm, 40 nm and 28 nm are also models with the word "5" in the middle. What will happen? We’ll leave right away.

Introduction of test platform and description of test method

　　In order to unify the performance of the platform, we use the high-end 3770K platform to ensure that it does not cause system bottleneck, which is more convenient for the performance of the graphics card. We use the latest driver 310.14 beta at present, and add a new game "Subway: The Last Dawn". Of course, the games all choose DX9 or DX10 running mode.

Theoretical test scores:

　　Because some graphics cards don’t support DX11, we tested 3DMark Vantage and the new 3DMark, and the results are for reference only.

　　Test summary:Judging from the test results, the progress of the three graphics cards is relatively balanced. The score displayed by 3DMark Vantage, GTS450 is twice as high as GTS250, regardless of its accuracy, at least the detected result mainly depends on the graphics card. As for the Cloud Gate scenario of the new 3DMark, it is more about the performance of the platform.

● Popular game masterpiece test

　　In order to make it easier for everyone to read, we have simplified the description of the game and compiled a variety of games into a big chart to make the comparison of the results more intuitive.

On the Significance of Game Frame Number (FPS)

　　The number of game frames is a standard to reflect whether the game runs smoothly, which can be classified in most cases.No playability:The number of frames is less than 30FPS；;Acceptable:30-50 frames;Smooth operation:50-60 frames;Perfect operation:The number of frames is greater than or equal to 60. That is to say, under normal circumstances, the number of frames is greater than 60, which is of little significance. At this time, you can increase the quality of the game to get more visual effects.

　　Now many new games use DX11 interface, and we adjust most of them to DX9 or DX10 mode. From the test of the game, GTS250 is not as bad as 3DMark Vantage shows. At least GTS450 is not twice ahead of GTS250, and the performance of the three in the game is more like the performance of the new 3DMark.

　　In addition, we also see that it is not impossible for GTS250 to play mainstream games in full HD resolution, but there is basically no enjoyment in image quality special effects.

　　To sum up the achievements of the three graphics cards, the performance improvement of each generation is about 20%. We can guess that GTX750 may be 120% of GTX650, and perhaps GTX750 is a GTX650Ti vest (see GTX770 vest GTX680).

Platform power consumption test:

　　Before the test, it should be noted that since the independent power consumption of the graphics card cannot be tested, all the power consumption scores in this round of test are the power consumption of the whole machine, and the power consumption tester is used for testing during the test. During the test, we run Tomb Raider 9 benchmark to test the average power consumption of the platform.

　　Test summary:The technology is more and more sophisticated, the architecture is more and more advanced, and the power consumption is lower and lower. In the previous GTS250, the power consumption of the platform was 238W, while the GTS450 with stronger performance was 225 W. In Kepler’s generation, the power consumption was as low as 158W W.

　　Compared with GTS250, GTS450′ s energy consumption progress is mainly achieved through the improvement of technology, and GTX650′ s performance is like this. In addition to the improvement of technology, streamlining general-purpose computing is also one of the means.

Summary of PConline evaluation room:

●GTS250 ladder diagram position guide

　　PConline ladder diagram description:From the test, it can be seen that the performance difference between GeFoece GTS250 and GTS450 is about 20%, which is smaller than that of GTS450 and GT640. We define that GTS250 has better performance than GT640, as shown above in the ladder diagram.

● What is the value of ●GTS250?

　　Looking back at GTS250, the listing price at that time was $149, which was close to 1,000 yuan at that time. What now? Although there are no new graphics cards, let’s go to the second-hand forum to see the current market.

The picture is intercepted in this forum (the value is also the best in 200 yuan)

　　At present, GTS250 is probably worth 250 yuan. In four years, the value has shrunk to 1/4 of that at that time. Once again, we must feel the fall in price speed of IT products. With the performance of GTS250, you can still enjoy the game now. The price in 200 yuan is better than buying a GT630.

●GTS250 upgrade or purchase suggestion.

　　At that time, with the GTS250 graphics card, most platforms used Xiaolong quad-core, Kourou E8400, or Kourou quad-core platforms. Compared with the current CPU performance, it is not bad, probably reaching the level of X4 740, and the performance can also be exerted with the current mid-range graphics card.

　　　For those friends who are about to retire from GTS250, we suggest to consider GTX650Ti, whose performance is far superior to that of GTS250, and its power consumption is lower than that of GTS250, and its energy consumption ratio is good. As for the friends who want to change to a new platform, according to the consumption level, they should buy the I5 grade at present, and of course they will match the GTX660Ti.

　　The improvement of GPU technology and the update of architecture can improve the performance and power consumption of graphics cards, which will be reduced to 1/4 in four years. After four years, is HD7990 worth 2K? In the next issue, we will test the previous God cards, such as GTX295 and HD4870x2, and now the performance is equivalent to what price of graphics cards.

　　As soon as the sky was white in the east, Gu Yuzhong, a ranger in Chedaoling, anding district, Dingxi City, Gansu Province, got on a motorcycle and entered the forest farm.

　　"The bitterness in the middle of Gansu is the best in the world." Dingxi has fragile ecology, serious soil erosion and high evaporation. Locals often say that in Dingxi, it is easier to plant a living tree than to raise a child.

　　This is the 30th year of Gu Yuzhong’s forest protection. "I am responsible for fire prevention, theft prevention and pest prevention of 1,300 mu of forest. Although it is hard, it is very meaningful, and there is a good income." Gu Yuzhong said.

　　Chedaoling Forest Farm has 8 mountain ridges and more than 50 gullies and bays, and more than 13,000 mu of land is now covered with "green clothes", with a forest coverage rate of 92.75%. There are 208 mu of nursery land and 800,000 seedlings in the nursery of forest farm, mainly including spruce, Platycladus orientalis, Pinus tabulaeformis, Robinia pseudoacacia, five-pointed maple, Populus hopeiensis and Sophora japonica.

　　The persistence of green supports people here to plant trees without stopping. After more than 60 years of unremitting efforts, a green barrier has finally been built on the driveway ridge across Yu’ an county.

　　Walking into Nanshan, anding district, Dingxi City, green spread. And three years ago, it was still a barren hill.

　　In 2017, the poverty alleviation cooperation between the east and the west helped Fuzhou, Fujian Province in Dingxi, and started with ecological poverty alleviation, funded the construction of ecological forests. Three years later, the afforestation area has reached 11,100 mu, with an investment of 45.99 million yuan.

　　"Under the extremely dry climate conditions in Dingxi, the key to afforestation is to solve the problem of water shortage." Chen Zhengbin, a member of the Party Committee of anding district Forestry and Grassland Bureau in Dingxi City, said that with the help of Fuzhou, they chose drought-tolerant tree species, added water-retaining agents during afforestation, and built water conservancy facilities at the same time, which led to this green field under their feet.

　　By September, 2020, anding district’s forestry land area accounts for 38% of the total land area, with 1,177,500 mu of natural grassland and a forest coverage rate of 17.98%. Satellite images show that in the past 20 years, Dingxi’s green has been expanding from point to line and from line to surface.

　　The mountain is called "tableland" here, with steep surroundings and flat top. The crack between the two mountains is called a "ditch", and a new road is paved at the bottom of the ditch, drifting away. Standing on a high place overlooking, Haloxylon ammodendron is a forest with dense vegetation. The once endless dry plateau is now covered with "green clothes" … …

　　— — Cadres of Procuratorate of Guangxi Zhuang Autonomous Region

　　He Wenkai and his wife’s anti-epidemic story

　　On January 27th, the third day of the first month, the news of COVID-19 outbreak in Wuhan was overwhelming, and Wuhan was in critical condition.

　　The epidemic is the order. At about 15 o’clock in the afternoon, there was a crowd in front of the gate of the inpatient department of the First Affiliated Hospital of Guangxi Medical University, and the first batch of Wuhan medical teams in Guangxi were ready to go.

　　He Wenkai, a cadre of the Information Office of the Procuratorate of Guangxi Zhuang Autonomous Region, took his eight-year-old daughter to bid farewell to his wife, Tang Lian, who was about to go to the front line.

　　"Dad, will mom be infected by that virus?" The daughter asked anxiously. "No, your mother is very capable and can protect herself." He Wenkai comforted his daughter. "Why does mom have to go?" The daughter asked again. "Many people in Wu Hanyou are ill, and doctors and nurses are not enough. Your mother is excellent, so she was chosen to treat them. "

　　But the child doesn’t know that from the moment he learned that his wife was about to rush to Wuhan, He Wenkai’s mood has been uneasy, and it seems to be mixed with some unspeakable tragic.

　　Go out resolutely

　　On the evening of January 25th, Tang Lian learned that Guangxi would send the first batch of medical teams to support Hubei to carry out medical treatment in COVID-19, so she collected volunteers.

　　"Many people in our hospital have signed up. Do you think I should sign up?" That night, she asked her husband for advice. "You sign up for the idea? But I support you, and I am honored that you are a retrograde person. " He Wenkai, who knows his wife, said with a smile.

　　Tang Lian is a nurse, deputy director of the Department of Respiratory Medicine, the First Affiliated Hospital of Guangxi Medical University. "She is professional, experienced and works in the respiratory department. She should be considered in the organization for such a respiratory disease epidemic." He Wenkai said.

　　Since my wife signed up, this family, which is full of laughter and laughter on weekdays, has suddenly become much quieter and the atmosphere has become somewhat dignified. "I don’t know what to say, neither of us is the kind of person who is a mother-in-law. As a husband, the question of whether she can go or not is contradictory. I hope that she will be selected and she will not be selected. After all, she is going to an epidemic area and facing such a strange and dangerous virus. "

　　The list of medical teams will be confirmed soon. Tang Lian is on the list. Later, He Wenkai learned that his wife was actually the first one to sign up in their hospital.

　　Ping An, checking in at the hotel. Late at night on January 27th, He Wenkai received Tang Lian’s WeChat.

　　The next day, He Wenkai wrote in his personal Weibo: My wife arrived in Wuhan last night. It is said that their medical team was stationed in Huangpi Chinese Medicine Hospital and began to help patients. No new message … …

　　Anti-COVID-19 Diary [1]:

　　My wife arrived in Wuhan last night. It is said that her medical team is stationed in huangpi district Chinese Medicine Hospital to help treat new pneumonia patients. No new message … …

　　On January 27th, Tang Lian went to war, and He Wenkai took his daughter to see him off.

　　● Weibo story ●

　　He Wenkai has 450,000 fans on Weibo. As a full-time cadre engaged in procuratorial news propaganda, he knows the significance of public opinion to this war of resistance at a time when the epidemic situation is raging and the whole country is fighting against COVID-19.

　　So He Wenkai began to write "Anti-COVID-19 Diary" in Weibo. In his view, supporting his wife and her medical care group in a different way, recording the vivid stories of prosecutors fighting against the epidemic and conveying the strong voice of the party and the government are not only personal records of current events of the times, but also the responsibility and mission of a procuratorial propagandist.

　　Anti-COVID-19 Diary [2]:

　　She has a master’s degree in medicine, and she is a nurse, deputy director of respiratory department. We discussed COVID-19, and I feel that they are not very knowledgeable about this disease in clinical practice. Maybe she has professional discipline and won’t talk to me about the details of the epidemic, which makes me nervous all the time. She said that she had been in the ward for a long time and was more resistant to bacteria. I hope so!

In the ward, Tang Lian and her colleagues mostly communicate through paper and pen.

He Wenkai and the staff of the Information Office planned the propaganda report on epidemic prevention of procuratorial organs.

　　The topic of "Anti-COVID-19 Diary" set off a hot discussion among netizens. As of press time, He Wenkai has written 43 "Diaries Against COVID-19", with the highest single reading volume reaching more than 80,000, and the total reading volume exceeding one million.

　　Anti-COVID-19 Diary [9]:

　　The child misses his mother. I specially made a postcard, took a video and sent it to Ann. The child said, I wish my mother good health, cure more patients and go home early.

During the period of aiding Hubei, Tang Lian’s happiest time was to have a video call with her children during the break.

Writing a diary of Weibo’s anti-epidemic is He Wenkai’s "homework" in the evening.

　　He Wenkai’s "Diary of Anti-COVID-19" is constantly updated. He writes about his wife and daughter, his procuratorial colleagues, and some "mortal charity" he has seen and heard. He also interacts with netizens and answers relevant legal questions.

　　Many strange netizens, including epidemic areas, learned from his diary in Weibo that the Guangxi medical team started medical treatment in Wuhan, and they forwarded, commented and liked it on Weibo, thanking all the people who made efforts to fight the COVID-19 epidemic.

　　User’s forwarding, comments and likes:

　　@CH00 ch00ling: As a girl in Guangxi, I am really proud! Please pay attention to safety and come back safely! Salute! The most beautiful doctor sister!

　　@ Almost ph: Our hometown, thank you for coming thousands of miles to support, and I hope everyone will be safe.

　　@ lazy pig a lazy pig: I hope this spring is still full of vitality, and my wife will arrive safely when the flowers bloom!

　　… …

　　He Wenkai’s wife also praised him: "I didn’t expect the influence to be so great. Even our colleagues know that you are writing Weibo’s diary, and everyone is encouraged."

　　second front

　　Since the outbreak of Xinguan pneumonia, the Information Office of the Procuratorate of Guangxi Zhuang Autonomous Region has entered the "fighting" mode early and has gone all out in the "second battlefield" to fight the epidemic. From the beginning of the Lunar New Year, the WeChat WeChat official account of the Procuratorate of Guangxi Zhuang Autonomous Region has continuously conveyed the good voice of Guangxi procuratorate in fighting the epidemic.

　　From January 25th to February 27th, the Information Office of the Procuratorate of Guangxi Zhuang Autonomous Region published more than 200 articles in various media at all levels. Only "Guangxi Procuratorate" WeChat WeChat official account has compiled and distributed 154 propaganda articles.

　　Anti-COVID-19 Diary [36]:

　　Heavy. As a middle and senior intellectual, Ann has always been a "mass" in politics, and has a strong desire to join the organization close to the Party. This time, the first batch went to Hubei with the Guangxi medical team to fight the COVID-19 epidemic, which has been improved ideologically and politically. Today, the firewire joined the party! From now on, in our family, I have the dual identity of husband and old party member. Honey, come on! Guangxi medical team, come on! Wuhan, come on!

Tang Li ‘an spoke as the representative of New party member at the ceremony of the medical aid team members joining the Party with Firewire.

It is the responsibility of the information office to report the "epidemic" situation of procuratorial organs in time and convey the positive energy of procuratorial work.

　　Because of the epidemic, my daughter’s school was delayed. Because his wife is not at home, the responsibility of taking care of the children falls entirely on He Wenkai. During the day, the child attends online classes at home by himself. When He Wenkai comes back from work at night, he has to help the child finish his homework and attend online interest classes. Only after the child falls asleep can he have his own time to think and deal with things at work.

　　The work of the information office is often a temporary task, which is very time-sensitive. He Wenkai often talks with his colleagues on the phone while explaining homework problems to his children. The child made a mistake and lost his temper and complained, "Dad, can you concentrate?"? ！” He Wenkai can only helplessly apologize to the child.

　　Meet the dawn

　　This more than a month, every Chinese may have mixed feelings. Those confusions and firmness, sadness and emotion are intertwined, which makes people witness the ruthlessness of the virus and the warmth of the world.

　　As of February 27th, more than 300 medical teams and more than 40,000 medical team members have been sent across the country to support Hubei.

　　Fortunately, every "retrograde person" is not alone, and both "small family" and "everyone" are their strong backing.

　　Anti-COVID-19 Diary [42]:

　　Ann has been in Wuhan for a month. Ann said that there are fewer and fewer new cases and deaths, and more and more cases are cured, so it’s time to return to Japan. I really have to come back early, and I can’t go home when I come back. I have to be isolated for half a month. The mountain flowers have blossomed, and the bluebird looks forward to the spring return.

He Wenkai: Resolutely win the people’s war, overall war and blocking war for epidemic prevention and control.

　　As He Wenkai wrote in his Weibo: "Ann has taken risks and hardships, and the great support given by the motherland and people makes people feel happy from the heart."

　　On February 27th, it was the 30th day that He Wenkai’s wife Tang Lian arrived in Wuhan. He Wenkai talked to his wife on the phone as usual, and her wife happily told her that the epidemic was under control. There were fewer and fewer new cases and deaths, and more and more cases were cured. Maybe she could go home soon.

　　"The mountain flowers have blossomed, and the bluebird looks forward to spring." On this day, He Wenkai wrote in Article 42 "Anti-COVID-19 Diary". In this battle without smoke, he and his wife have experienced a lot and grown a lot. I believe that after experiencing the storm, they can watch the spring more calmly.

　　(Text: Chen Yingjie)

　　BEIJING, Zoucheng, Feb. 20 (Zeng Jie, Wang Chongyin) Since the ninth day of the first lunar month, the lost skill "Tie Tie Hua" has reappeared in Gelushan, Zoucheng, Shandong Province, the hometown of Taoist culture. With the gradual decline of the iron smelting industry in the last century, the blacksmith’s artistic performance "Beating the Iron Flower" once disappeared from people’s field of vision.

　　In an interview with Gelushan in Zoucheng on the night of the 21st (the 12th day of the first month), the reporter saw that 71-year-old Kong Lingfa and 46-year-old Kong Lingshuang went into battle shirtless and danced "flower sticks" with thousands of degrees of molten iron in various postures in the sound of gongs and drums. Iron juice splashed on a nearby prop-a big willow with many branches, and then turned into a giant flower with the help of wicker posture. The onlookers held their breath first, then cheered and screamed, calling it the most "thrilling" performance in the first month.

　　"How can the first month of Gelushan not be spent while the iron is hot?" While the iron is hot, Hua returned to Gelushan, which made Kong Lingfa in seventy years of age feel very excited. He told reporters that his family was engaged in iron smelting in the late Qing Dynasty, and playing iron flower was a "talent" performance that his family was proud of. As the fourth generation of his family, he witnessed the prosperity and decline of playing iron flower.

　　Kong Lingfa introduced that the cultural origin of Gelushan and Taoism was recorded in the Old Records of Zouxian County. In ancient times, five craftsmen of gold, silver, copper, iron and tin called each other brothers and respected the old gentleman on the Grand Master as the ancestor. During the Spring Festival, they sacrificed while the iron was hot. Since the Ming Dynasty, many famous iron smelting craftsmen have emerged here, and the performance of Gelushan while the iron was hot continued from the Ming Dynasty to the 1980s.

　　By the time the young Kong Lingfa "played with a flower stick", folk customs such as dragon dancing, playing bronze wares and knocking on gongs and drums had been absorbed, and striking iron flowers became the most imposing and joyful program in the first month of Gelushan.

　　It is reported that Tie Hua was listed in the national intangible cultural heritage list as early as 2008. There was no inheritor of this skill in Gelushan at that time. Kong Lingfa, who gave up the iron smelting business, has already become an out-and-out farmer.

　　Gao Dewen, director of Zoucheng Cultural Center, told reporters that Kong Lingfa and Kong Lingshuang, who are stunted, were discovered by Zoucheng Intangible Heritage Protection Center in 2015 and selected as inheritors. The Spring Festival of the Year of the Monkey is the first time that they started their "acting career" as non-genetic inheritors.

　　Kong Lingfa is from Beige Village, Dashu Town, Zoucheng, and Kong Lingshuang is from Henghe Village, Daping Town. These days, the two are leading more than a dozen young people to step up rehearsals for the official performance of the Lantern Festival. According to Gao Dewen, it can be seen from the recent audition that while the iron is hot, flowers are loved by the audience.

　　"Playing while the iron is hot once brought people infinite joy and excitement." Gao Dewen, who has been engaged in the rescue of intangible cultural heritage for a long time, said that playing while the iron is hot has strong entertainment and appreciation. Although the iron smelting industry in Gelushan area has declined now, playing while the iron is hot should return to the public’s field of vision and become an artistic performance in festivals.

　　Gao Dewen said that the metallurgical culture in Taoist alchemy pharmacy and the prosperous history of iron smelting industry in this area have been written into the newly compiled Zoucheng Literature and History Materials, and the flower while the iron is hot has also gone down in history as a cultural symbol here.

In February, automobile sales reached 13,209 units, up 9.26% year-on-year. Among them, the Lectra EM-P family contributed a lot, accounting for about 47% of the sales. In order to achieve further progress, the Lectra EM-P family added a new member-Lectra 07 EM-P. Based on CMA Evo architecture, the new car will be positioned as a medium-sized car, adopting the second generation design language of Lectra and equipped with a 1.5T plug-in system, which will be officially released on March 8th. A few days ago, some netizens have photographed the real car map of the Lectra 07 EM-P. Let’s take a look.

Judging from the actual car diagram, the LECK 07 EM-P continues the family design language of LECK 08 EM-P, and the low-lying closed front is equipped with "Dawn" daytime running lights on both sides, and the far and near light groups below are in a penetrating style, and a point array linear light source is added in the middle, giving consideration to the sense of science and technology and recognition. The outward extension of the trapezoidal lower grille also outlines the "beard" style, which looks both individual and sporty.

The style of the side of the car body is quite similar to that of the car body. The slip-back C-pillar shape, together with the rising window line and waist line, creates a posture ready to go, and is also equipped with frameless doors, hidden door handles, suspended roof and two-color dynamic petal-shaped wheels, which further enhances the sense of movement and fashion. In addition, the exterior rearview mirror is also designed with a narrow frame, which also uses a relatively thick bracket and incorporates a camera. The body dimensions are 4827/1900/1480mm, and the wheelbase is 2843mm.

The tail adopts a long and narrow through taillight group, and four prominent column light groups complement each other with the style of the whole vehicle, and dot-matrix light sources are also added inside to echo the front face. In response to this, there is also a blackened diffuser extending outward, coupled with the upturned blackened duckling tail, and the sense of fighting is vividly portrayed. In addition, the new car will also provide a variety of styling wheels, NFC keys, privacy glass and so on.

Combined with the previously exposed interior spy photos, it also continues the design style of Lectra 08 EM-P. The simple center console is equipped with a suspended central control large screen and a rectangular full LCD instrument panel, and it is expected to be equipped with the Flyme Auto car system. The three-position multi-function steering wheel is also the same as the Lectra 08 EM-P, and the dual mobile phone wireless charging panel is not absent. It is understood that the Lectra 07 EM-P will also be equipped with a million-level panoramic sound response system, a 92-inch AR-HUD, a full-cabin seat with the same power, and an ecological interconnection between people and cars.

As for the power, the Lectra 07 EM-P will be equipped with an EM-P hybrid system consisting of a 1.5T engine +3DHT gearbox+drive motor, in which the maximum power of the 1.5T engine is 120kW, which is consistent with that of the Lectra 08 EM-P.. As a reference, the comprehensive power of the Lectra 08 EM-P two-wheel drive system is 280kW(381 HP) and the four-wheel drive system is 436kW(593 HP). According to the application information, the Lectra 07 EM-P is equipped with a battery pack with a capacity of 18.99kWh, with a pure battery life of 102km and a fuel consumption of 4.8L/100km.

It is worth mentioning that the sales target of the brand is 300,000 vehicles in 2024. In addition to the 07 EM-P, a number of new cars will be launched this year, including not only a large-scale ultra-luxury flagship model, but also the first pure electric car (code name "E371"), which will adopt a global 800V and AI chassis (double-cavity suspension +CDC electromagnetic suspension). It seems that Xiaomi SU7 has

Of course, the information about the new car has yet to be officially announced. So, what do you think of Lectra 07 EM-P? Starting from the guide price of Lectra 08 EM-P of RMB 208,800, what do you think is the appropriate price of Lectra 07 EM-P? Welcome to leave a comment.

The immune system can also get sick and even be life-threatening.

　　"Wang Lin, a qigong master, died of multiple organ failure due to ANCA-related vasculitis and autoimmune peripheral neuritis." This news brought "immune system diseases" into public view.

　　In the course of millions of years of evolution, human beings have formed a complex defense mechanism against foreign microorganisms and harmful substances. This defense mechanism has a clear division of labor and powerful functions, and can cope with the changes and challenges of the living environment. We call it "immune system".

　　But like other organs of the human body, the immune system will get sick and even be life-threatening. What’s wrong with this?

　　The innate immune system is derived from invertebrates.

　　The normal immune system consists of immune organs, immune cells and immune molecules.

　　Immune organs mainly refer to lymph nodes, spleen and thymus. Among immune cells, there are cells involved in immune response and immune regulation, mainly T lymphocytes and B lymphocytes. Among them, T lymphocytes come from thymus and play an important role in the regulation of immune response, while B lymphocytes are mainly involved in the formation of antibodies, including autoantibodies. Immune molecules are mostly synthesized and secreted by immune cells, which play an important role in the initiation and regulation of immune response and the attack on tissues and organs.

　　Humans have inherited the innate immune system of invertebrates in the process of evolution. This ancient defense system identifies invading external pathogenic microorganisms through germinal cells widely distributed in human immune organs; Through the macrophages of innate immune system, we can identify the virulence factors of main microorganisms, directly kill pathogens and protect human body. This kind of protection is an immune response that is quickly started and mobilized, and it is non-specific. That is to say, innate immunity is reacted and cleared in the same way for any foreign microbial invasion, so it is not the most effective.

　　However, while the innate immune system slows down infection, it will activate the acquired immune system-the acquired immune system. Acquired immunity will react specifically to foreign antigens or pathogens. After the first contact with antigens, the second contact with the same antigen can trigger a faster and stronger immune response, attack foreign antigens and remove them from the body.

　　In short, the normal immune system has three important characteristics: one is a variety of antigen receptor libraries, which can identify almost endless pathogens; The second is immune memory, which can initiate a rapid memory immune response, which is why we can be immune for life after injecting some vaccines; The third is immune tolerance to avoid immune damage to normal self-tissues.

　　Distinguish the Immune Tolerance of "Friend or Foe"

　　The most important function of so-called "immunity" is to identify "self" and "non-self", and it will not produce immune response to its own tissue components, which is called immune tolerance.

　　The human body can achieve immune tolerance through autoantigen isolation, so that its own tissues can not contact with the immune system, and the specific immunity of related T or B cells is "unresponsive". For the "non-ego" of foreign microorganisms or foreign tissues and organs introduced into the body, the immune system will protect the body from the damage of intruders by starting an immune "response" reaction.

　　Therefore, if the function of the immune system is disordered and the normal components of the body are regarded as foreign substances, autoimmune diseases will occur. From the pathogenesis, autoimmune diseases are diseases caused by the breaking of immune tolerance. The immune system cannot correctly identify "self" and "non-self", thus attacking its own tissues and organs.

　　In addition, the dysfunction of T cells with the function of regulating immunity can not stop or inhibit the immune response in time, which will also lead to the occurrence of autoimmune reaction.

　　Autoimmune diseases are related to genes.

　　It is necessary for us to understand the role of genes in autoimmune diseases.

　　In the process of immune response, many auxiliary molecules are needed to produce specific immune response against foreign microbial antigens. Among them, the most important helper molecule is MHC (major histocompatibility complex). T cells can be activated and the subsequent immune response can be initiated only after the foreign microbial antigen and MHC molecules combine to form a complex.

　　MHC is usually called human leukocyte antigen (HLA), and its related gene is located on chromosome 6. HLA antigen complex is regarded as the genetic determinant of immune activation. In other words, HLA mainly determines the characteristics of immune response and the occurrence and development direction of immune response. At present, more and more genetic studies show that HLA determines a person’s susceptibility to many diseases, especially autoimmune diseases. People who carry these susceptibility genes have a much higher risk of autoimmune diseases than the general population.

　　In reality, scientists have found some susceptible genes related to autoimmune diseases. It is certain that human immune response is influenced by genetic factors, and some autoimmune diseases have genetic tendencies.

　　People with genetic susceptibility should beware of "molecular simulation"

　　Generally speaking, autoimmune diseases often occur in genetically susceptible people. Their immune cells have abnormal functions, and they will get sick when they encounter suitable external triggers.

　　These external triggers include microorganisms, such as some bacterial or viral infections, and some harmful substances in the environment, such as smoking. For example, some microbial antigens, such as staphylococcal protein A and staphylococcal enterotoxin, can stimulate T or B cells, making these cells transform into autoreactive T or B cells, leading to autoimmune reactions.

　　In addition, because the components of some microorganisms are similar to the fragments in normal human tissues, the normal immune response to foreign microorganisms will activate autoimmune lymphocytes in the form of "molecular simulation" or cross-reaction, causing autoimmune reactions. The most typical autoimmune disease caused by molecular simulation is rheumatic fever. The anti-Streptococcus M protein antibodies in rheumatic fever cross-react with actin, laminin and antigens of nervous system, and start inflammatory reaction in the heart, causing rheumatic heart disease. If these antibodies enter the brain tissue, they can cause chorea. Studies have shown that in type I diabetes, rheumatoid arthritis and multiple sclerosis, there is a "molecular simulation" effect between this microbial protein and human tissues.

　　In a word, the immune system is a delicate and complex barrier to protect the body from external harm. However, the pathogenesis of autoimmune diseases is very complicated, so far, the exact pathogenesis of a considerable number of diseases has not been fully studied. It should be noted that after the occurrence of autoimmune diseases, patients should seek medical advice in time, diagnose and treat early, so as to avoid irreversible damage to important organs.

　　(1) 2021 is the first year of the 14th Five-Year Plan. Today’s China is showing a magnificent picture based on the new development stage, implementing the new development concept, building a new development pattern and promoting high-quality development.

　　Looking at China, people’s enthusiasm for consumption is warming up with the vast land. From the rapid recovery of travel and tourism, from the continuous upsurge of online new consumption, and from the transportation and logistics connecting more than 9.6 million square kilometers of land, we can feel the great potential of China’s strong domestic market. With the global economic recovery, China’s major coastal ports are busy or even "hard to find a box", and a number of maritime ships connect China with the world, demonstrating China’s determination to build a higher level of open economy. Efforts will be made to make the domestic big cycle smoother, make the domestic and international double cycles complement each other, and build a new development pattern showing a good momentum.

　　The year 2021 is of special importance in the process of China’s modernization. The Communist Party of China (CPC) celebrates its centenary birthday, unites and leads the people of all ethnic groups to build a well-off society in an all-round way, takes advantage of the situation to start a new journey of building a socialist modern country in an all-round way and March towards the goal of the second centenary. Facing the interweaving of the epidemic situation in the century and the changes in the century, and facing the profound and complex changes in the development environment at home and abroad, the CPC Central Committee with the Supreme Leader as the core is far-sighted and sized up the situation, and has made a major strategic decision to accelerate the construction of a new development pattern with the domestic macro-cycle as the main body and the domestic and international dual cycles promoting each other. The "14th Five-Year Plan" approved by the Fourth Session of the 13th National People’s Congress and the outline of the long-term goals for 2035 depict the grand blueprint for China’s future development and make major work arrangements for accelerating the construction of a new development pattern.

　　At the National People’s Congress this year, the General Secretary of the Supreme Leader pointed out: "Based on the new development stage, implementing the new development concept, building a new development pattern and promoting high-quality development are the tasks that the whole party and the whole country must pay close attention to at present and in the future." During the 27th collective study in the Political Bureau of the Communist Party of China (CPC) Central Committee, General Secretary of the Supreme Leader emphasized: "Do a good job in this year’s economic and social development and make progress ‘ Fourteenth Five-Year Plan ’ The first step of China’s development in the period is very important. The first step is to take a steady step, take a new look and achieve new results. " "The whole party must implement the new development concept completely, accurately and comprehensively to ensure ‘ Fourteenth Five-Year Plan ’ During the period, China’s development started well and took a good step. " During his inspection tour in Fujian, the General Secretary of the Supreme Leader stressed that it is necessary to "find a correct position in service and integration to build a new development pattern" and "show greater achievements in service and integration into the new development pattern".

　　Start a new journey, set sail and start again. China has a clear development orientation, clear goals and clear paths.

　　(2) A correct understanding of the historical position and development stage of the cause of the party and the people is the fundamental basis for our party to clarify the central tasks at different stages and formulate the line, principles and policies, and it is also an important experience for our party to lead the revolution, construction and reform to win continuously. Entering the new development stage has defined the historical position of China’s development, and to build a new development pattern, we must first deeply understand the new development stage. At present, great historical achievements have been made in building a well-off society in an all-round way, and comprehensive victory has been achieved in the battle against poverty. We are standing at the historical intersection of the goal of "two hundred years". General Secretary of the Supreme Leader stressed: "The new stage of development is the stage of building a socialist modern country in an all-round way and marching towards the goal of the second century. This is a milestone in China’s development process. "

　　Entering a new stage of development is a great leap in the historical process of the great rejuvenation of the Chinese nation. Since the founding of the Communist Party of China (CPC), all the struggles that the people of China have united and led are aimed at building China into a modern power and realizing the great rejuvenation of the Chinese nation. From the first five-year plan to the fourteenth five-year plan, the consistent theme is to build China into a socialist modern country. After the development during the Thirteenth Five-Year Plan period, China’s economic strength, scientific and technological strength, comprehensive national strength and people’s living standards have leapt to a new level. Building a well-off society in an all-round way as scheduled and winning the battle against poverty have made the great rejuvenation of the Chinese nation take a new step forward, laying a solid foundation and creating favorable conditions for building a socialist modern country in an all-round way in the new stage of development. Shortly after the founding of New China, our party put forward the goal of building a socialist modern country, and the next 30 years will be a new stage of development for us to fulfill this historical ambition.

　　Entering a new stage of development, we must profoundly grasp the important characteristics of China’s modernization. The modernization we are promoting is a modernization with a huge population. If 1.4 billion people want to enter the modern society as a whole, it will completely rewrite the modern world map, which is a major event with far-reaching influence in human history. It is the modernization of common prosperity for all the people. We adhere to the people-centered development thought, consciously and actively solve the regional gap, the urban-rural gap and the income gap, and promote social fairness and justice. It is a modernization in which material civilization and spiritual civilization are in harmony. We adhere to the socialist core values, strengthen the people’s spiritual strength, and promote the all-round enrichment of things and the all-round development of people. It is the modernization of harmonious coexistence between man and nature. We pay attention to the simultaneous promotion of material civilization construction and ecological civilization construction, and take the road of civilized development of production development, affluent life and good ecology. It is a modernization that takes the road of peaceful development. We emphasize mutual benefit and win-win with all countries in the world, promote the building of a community of human destiny, and strive to contribute to the peace and development of mankind. Practice shows that Chinese-style modernization not only conforms to the reality of China and embodies the law of socialist construction, but also conforms to the general trend of the world and embodies the law of human social development.

　　Entering the new stage of development, we must profoundly grasp the new connotation of the period of important strategic opportunities for China’s development. At present and in the future, China’s development is still in an important period of strategic opportunities, but there are new developments and changes in both opportunities and challenges. Most of them are unprecedented, and overall opportunities outweigh challenges. Internationally, the century-old change has accelerated its evolution, the world has entered a period of turbulent change, and the external environment has become more unstable and uncertain. The key is to accurately understand the key factors that determine the direction of the world’s unprecedented change, maintain strategic strength, grasp strategic initiative, stand on the right side of history, hold high the banner of building a community of human destiny, unswervingly safeguard and lead economic globalization, actively participate in the reform and construction of the global governance system, and strive to create an external environment conducive to China’s development. Domestically, China has turned to the stage of high-quality development, and its continued development has many advantages and conditions, but it also faces many difficulties and challenges. The key is to look at the problem from a comprehensive, dialectical and long-term perspective, deeply understand the changes in major social contradictions, enhance the system of solving the problem of insufficient development imbalance, deeply understand the people’s yearning for a better life, enhance the pertinence of solving the problem of insufficient development imbalance, deeply understand the fundamentals of long-term economic improvement, and enhance the confidence in solving the problem of insufficient development imbalance, and unswervingly implement it. Generally speaking, crises coexist, crises are organic, crises can turn around, opportunities are more strategic and plastic, challenges are more complex and overall, challenges are unprecedented, and opportunities are unprecedented if we deal with them well.

　　From now until the middle of this century, it will be 30 years for China to build a socialist modern power in an all-round way. Building a socialist modern country in an all-round way in the new stage of development will not be a smooth sailing process, and we must make even harder efforts.

　　(3) The strategic issue is the fundamental issue of a political party and a country. With accurate strategic judgment, scientific strategic planning and strategic initiative, the cause of the party and the people will be promising. Looking back at history, in each period, our party always made new strategic decisions according to the new development situation, new historical tasks and new environmental conditions, and led the China to sail to more open waters.

　　General Secretary of the Supreme Leader stressed: "Building a new development pattern is a strategic choice to keep pace with the times and improve China’s economic development level, and it is also a strategic choice to shape China’s new advantages in international economic cooperation and competition." It is necessary to realize that in the face of severe and complicated situations, we must adhere to the bottom line thinking and make ideological preparations and work preparations for dealing with changes in the external environment for a long time. At the same time, many problems we encounter are also medium and long-term, and we must understand them from the perspective of protracted war. Building a new development pattern is put forward according to the changes in China’s development stage, environment and conditions. It is a major decision made with a view to solving medium-and long-term problems and preparing for a protracted war. It is an important way to achieve a long-term balance between stable growth and risk prevention. It is a systematic and deep-seated change that concerns the overall situation. It is a strategic plan based on the present and with a long-term perspective. We should accurately grasp the strategic deployment of accelerating the construction of a new development pattern from the overall situation and strategic height.

　　Building a new development pattern is a conscious grasp of China’s objective economic laws and development trends, and has a profound practical foundation. Since the reform and opening-up, China has persisted in opening its doors for construction, and successfully achieved a great turning point from closed and semi-closed to all-round opening, which not only developed itself, but also benefited the world. Especially after China’s accession to the World Trade Organization in 2001, China has deeply participated in the international division of labor and integrated into the international cycle, forming a development pattern of "two ends outside" of market and resources, which has played an important role in seizing the opportunity of economic globalization to rapidly enhance economic strength and improve people’s lives. In recent years, with the changes in the global political and economic environment, the trend of anti-globalization has intensified, and the traditional international cycle has obviously weakened. In this case, efforts to build a new development pattern, based on the advantages of domestic market and relying on domestic market, and fully tap the potential of domestic demand are conducive to resolving the impact of external shocks and the decline in external demand, and also conducive to ensuring the basic normal operation of China’s economy and overall stability of the overall social situation in extreme cases. As the General Secretary of the Supreme Leader emphasized: "Only by standing on our own feet and smoothing the domestic circulation can we let the international situation change and always survive and develop with vigor." To build a new development pattern is to enhance our viability, competitiveness, development and sustainability in all kinds of foreseeable and unpredictable storms and stormy waves.

　　It is not only necessary but also feasible to construct a new development pattern. The proportion of China’s total economic output in the world has risen from less than 2% at the beginning of reform and opening up to more than 17% in 2020, and it has a very large scale. From the perspective of international comparison, the characteristics of big country economies are that domestic demand is dominant and internal circulation is possible. As the second largest economy and the largest manufacturing country in the world, the relationship between domestic economic cycle and international economic cycle has long required adjustment objectively. Since the 18th National Congress of the Communist Party of China, we have adhered to the strategy of expanding domestic demand, making development more dependent on domestic demand, especially consumer demand. China’s dependence on foreign trade has dropped to 31.8% in 2019, and the ratio of current account surplus to GDP has dropped to about 1% at present. The contribution rate of domestic demand to economic growth has remained above 90% in most years and over 100% in some years. China has a population of 1.4 billion, and its per capita GDP has exceeded 10,000 US dollars. It is the largest and most potential consumer market in the world, with huge room for growth. In the coming period, the characteristics of China’s domestic market leading economic cycle will become more obvious, and the domestic demand potential of economic growth will be continuously released. We are fully qualified to put our development foothold at home, rely more on the domestic market to achieve economic development, build a new development pattern and reshape new competitive advantages.

　　With the continuous improvement of China’s economic strength, scientific and technological strength and comprehensive national strength, the relationship between China and the world is undergoing profound changes. In the past, when our level of development was low, we were more complementary to others. Now that our level of development has improved, our competitiveness with others has increased. This is completely an objective reality that does not depend on human will in the process of historical development. Whether adapting to the changes in the global political and economic environment or adapting to the laws of China’s economic development requires us to build a new development pattern.

　　(D) General Secretary of the Supreme Leader stressed: "We are building a new development pattern, which is by no means a closed domestic single cycle, but an open and mutually reinforcing domestic and international double cycle." To speed up the construction of a new development pattern, we must properly handle the relationship between domestic and international cycles.

　　It should be recognized that the new development pattern with the domestic macro-cycle as the main body and the domestic and international dual-cycle promoting each other is a whole, and one aspect cannot be separated and emphasized unilaterally. China’s economy has been deeply integrated into the world economy, and its industrial correlation and interdependence with many countries around the world are relatively high. Domestic demand and external demand are interdependent and mutually reinforcing. China-Europe trains have accumulated more than 35,000 trains, and the number of cities opened has expanded from Chongqing to over 60, covering the whole of Europe. On this international channel, cross-border e-commerce has found a new way to go to sea, and freight trains have become "new postmen" in Eurasia. This fully shows that taking the domestic macro-cycle as the main body is by no means a closed operation behind closed doors, but by exerting the potential of domestic demand, the domestic market and the international market can be better connected, and the domestic macro-cycle can attract global resource elements, make better use of the domestic and international markets and resources, improve the ability to allocate resources in the world, and better strive for strategic initiative in open development.

　　China’s super-large-scale market potential should be fully tapped with the domestic large-scale circulation as the main body. A set of data is intriguing: as of March 24, China’s express delivery business exceeded 20 billion pieces this year, close to the level of 2015; 1-mdash this year; In February, the total retail sales of social consumer goods increased by 33.8% year-on-year, 1-mdash; It increased by 6.4% in February, with an average growth of 3.2% in two years, and the market sales maintained growth; The added value of industrial enterprises above designated size increased by 35.1% year-on-year, 1-mdash higher than that in 2019; In February, the growth rate was 16.9%, with an average growth rate of 8.1% in two years, which was a higher level in the same period in recent years; In February, China’s movie box office reached 12.265 billion yuan, creating a global single-month box office record. In terms of demand, China has a population of 1.4 billion, including more than 400 million middle-income groups; From the supply point of view, China has the largest, most comprehensive and complete manufacturing system in the world, with 130 million market players and more than 170 million talents with higher education or various professional skills. It has a strong production capacity based on the domestic market, which can promote the integration and innovation of global factor resources and maximize the scale effect and agglomeration effect. Tightly grasping the main line of supply-side structural reform, adhering to the strategic basis of expanding domestic demand, paying attention to demand-side management, and making production, distribution, circulation and consumption rely more on the domestic market, we can form a higher level of dynamic balance of demand pulling supply and supply creating demand, and improve the overall efficiency of the national economic system.

　　To realize the mutual promotion of domestic and international double circulation, it is necessary to implement high-level opening up and open up a new situation of win-win cooperation. When the epidemic brought heavy losses to the global economy, China not only provided support and shared experiences to many countries, but also held major international economic and trade activities such as Canton Fair, Service Trade Fair and China International Import Expo(CIIE) one after another, and declared its firm determination to open wider to the outside world with sincere actions. When unilateralism and trade protectionism prevail and economic globalization encounters great challenges, the door of China’s opening to the outside world is not closed, but it is getting wider and wider. In 2020, China’s total import and export of goods in the whole year was 32,155.7 billion yuan, up by 1.9% over the previous year. The total value of import, export and export both reached record highs and continued to rank first in global trade in goods. The actual use of foreign direct investment in the whole year was 1 trillion yuan, an increase of 6.2% over the previous year. China’s economic development in the past 40 years has been achieved under open conditions, and it is the consensus of China society that China’s economy must achieve high-quality development under more open conditions in the future. Only by scientifically understanding the relationship between domestic macro-cycle and domestic and international dual-cycle, responding to "anti-globalization" with high-level openness, responding to the so-called "divestment theory" with improved business environment, responding to the so-called "decoupling theory" with the attraction of super-large-scale market, building a new open economic system with a higher level, and implementing a wider, wider and deeper opening up can we continue to promote reform and development through openness and achieve high-quality development under more open conditions.

　　In practice, to build a new development pattern, it is necessary to clarify vague understanding and prevent misunderstanding. For example, they do things in their own way, draw the land as a prison, and do not care about building a unified national market and engaging in their own small cycle; For example, it is considered that smooth economic circulation means smooth logistics and low-level logistics circulation; For example, when it comes to solving the technical problem of "sticking the neck", it does everything by itself, engages in redundant construction, and focuses on the "high-rise" project, regardless of the objective reality and industrial base, and the result is an unfinished project; For example, when it comes to expanding domestic demand and forming a large domestic market, it starts to borrow blindly to expand investment, over-stimulate consumption, and even engages in projects with high energy consumption and high emissions … … If these problems are not taken seriously, it will have an adverse impact on building a new development pattern. Only by accurately understanding the connotation of the new development pattern can we take the first step and see a new atmosphere in the practice of building a new development pattern.

　　(5) Idea is the forerunner of action, and certain development practices are led by certain development ideas. General Secretary of the Supreme Leader emphasized: "The development in the new era and new stage must implement the new development concept and must be high-quality development." "The new development concept and high-quality development are internally unified, and high-quality development is the development that embodies the new development concept." To build a new development pattern, we must unswervingly implement the new development concept, constantly solve development problems, cultivate development advantages, and better achieve high-quality development.

　　One of the most important aspects for our party to lead the people in governing the country and politics is to answer the important question of what kind of development to achieve and how to achieve it. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has made a scientific judgment on the economic situation, put forward many major theories and ideas on economic and social development, and made timely adjustments to development concepts and ideas, among which the new development concept is the most important and the most important, which has led to historic achievements and changes in China’s economic development. The new development concept is a systematic theoretical system, which answers a series of theoretical and practical questions about the purpose, motive force, way and path of development, and expounds the political stand, value orientation, development mode and development path of our party. Practice has fully proved that the new development concept is a baton and a traffic light, which is a concentrated expression of China’s development ideas, development direction and development focus, and is the direction of managing the overall situation, managing the fundamentals and managing the long term.

　　During the "Thirteenth Five-Year Plan" period, the new development concept gave full play to its leading and guiding role, providing a guide for China to transform its economic development mode, optimize its economic structure, transform its growth momentum and move towards high-quality development. In 2020, China’s GDP will exceed 100 trillion yuan, the urbanization rate of permanent residents will exceed 60%, and people’s demands for a better life will continue to increase … … At present, the major social contradictions in our country have undergone historic changes, and the contradictions and problems in development are mainly reflected in the quality of development, which requires us to put the quality of development in a more prominent position and strive to improve the quality and efficiency of development. Practice tells us that the more difficult and challenging development is, the more confident we must be, the more determined we must be, insisting that the green hills will not relax, insisting on guiding the overall development with new development concepts, making efforts to solve structural and institutional contradictions and problems that restrict development, and striving to create a new realm of development.

　　The Fifth Plenary Session of the 19th CPC Central Committee made a systematic plan and strategic deployment for China’s development during the 14th Five-Year Plan period, and made it clear that the theme was to promote high-quality development and that the principle of adhering to the new development concept must be followed. "High-quality development is the development that embodies the new development concept, and it is the economic development from ‘ Is there ’ Turn ‘ Ok ’ 。” Implementing the new development concept has clarified the guiding principles of China’s modernization, and building a new development pattern has clarified the path choice of China’s economic modernization. Based on the new development stage and building a new development pattern, only by completely, accurately and comprehensively implementing the new development concept, making it work together to form a joint force, insisting on quality first and efficiency first, effectively changing the development mode, and promoting quality change, efficiency change and power change can we achieve higher quality, more efficient, fairer, more sustainable and safer development.

　　The new development concept is a whole, insisting on innovative development, coordinated development, green development, open development and shared development. The whole party and the whole country should unify their thinking, coordinate their actions and forge ahead. Whether at the central or departmental level, whether at the provincial level or below, we must fully grasp, accurately understand and fully implement the new development concept in the whole process of economic and social development and in all fields.

　　(6) "No matter how many times you have heard the growth story of China, it still has amazing capabilities." Looking forward to the future of China, some international media say so. The important aspect of this "amazing ability" is our party’s ability to lead development.

　　The General Secretary of the Supreme Leader stressed: "We should strengthen the Party’s overall leadership over socialist modernization" and "promote the Party’s leadership over socialist modernization to be more scientific and reasonable in functional allocation, more complete and perfect in system and mechanism, and more efficient in operation and management". The broad masses of party member cadres, especially leading cadres at all levels, must base themselves on the two overall situations, be mindful of "the leader of the country", constantly improve their political judgment, political understanding and political execution, constantly improve their political ability, strategic vision and professional level in grasping the new development stage, implementing the new development concept and building a new development pattern, dare to take responsibility and be good at doing things, and implement the decision-making arrangements of the CPC Central Committee.

　　Accelerating the cultivation of a complete domestic demand system is an important basis for smoothing the national economic cycle and strengthening the main position of the domestic big cycle. The key to building a new development pattern lies in the unimpeded economic cycle, and the formation of a strong domestic market is its important support. It is necessary to establish an effective system to expand domestic demand, release the potential of domestic demand, expand residents’ consumption, and raise the level of consumption, so as to make the construction of a super-large domestic market a sustainable historical process. Efforts should be made to break through the key blocking points that restrict the economic cycle, organically combine the implementation of the strategy of expanding domestic demand with deepening the structural reform of the supply side, improve the adaptability of the supply system to domestic demand, improve the integrity of the industrial chain and supply chain, and make the domestic market the main source of final demand.

　　Speeding up the self-reliance of science and technology is the key to ensure the smooth domestic circulation and shape China’s new advantages in the international circulation. The most essential feature of building a new development pattern is to achieve a high level of self-reliance and self-improvement, and we must put more emphasis on independent innovation. Only by mastering the core technologies in our own hands can we truly grasp the initiative of competition and development and fundamentally safeguard national economic security, national defense security and other security. We should adhere to the core position of innovation in the overall situation of China’s modernization, strengthen the national strategic scientific and technological strength, comprehensively strengthen the deployment of scientific and technological innovation, pool superior resources, vigorously and orderly promote the system and mechanism of "unveiling the list and taking the lead" in tackling innovative problems, strengthen the docking between innovation chain and the industrial chain, lay a solid battle for key core technologies, and accelerate the capture of "stuck-neck" technologies in important fields.

　　Promoting the optimization and upgrading of the industrial chain supply chain is an urgent need to stabilize the main position of the domestic big cycle and enhance the driving ability in the international big cycle. Manufacturing is the lifeblood of China’s economy, the foundation of the country and the foundation of a strong country. The security and stability of industrial chain supply chain is the basis of building a new development pattern. In the fight against the epidemic, China’s complete manufacturing system has played a vital supporting role, once again proving the importance of manufacturing to the development and security of the country, especially big countries. It is necessary to promote the completion of short boards and forging long boards as a whole, implement key core technology research projects for weak links in the industry, give more importance to enhancing the toughness and competitiveness of the industrial chain, and strive to build an independent, controllable, safe and efficient industrial chain supply chain.

　　To promote the modernization of agriculture and rural areas, the urban-rural economic cycle is an important aspect of the domestic cycle, and it is also a key factor to ensure the healthy relationship between the domestic and international cycles. Realizing the modernization of agriculture and rural areas is an important task of building a socialist modern country in an all-round way and an inevitable requirement to solve the problem of insufficient development imbalance. We should persist in taking solving the problems concerning agriculture, rural areas and farmers as the top priority of the Party’s work, fully implement the strategy of rural revitalization, persist in promoting the structural reform of agricultural supply side, implement the strategy of storing grain in the land and storing grain in technology, ensure food security and ensure that Chinese’s rice bowl is firmly in its own hands.

　　Improving people’s quality of life is the starting point and the end result of unblocking the domestic big cycle, and it is also the key connection point of mutual promotion of domestic and international double cycles. It is the fundamental purpose of socialist production to adapt to the changes in people’s needs, strive to run various livelihood undertakings well, and make people’s lives better and better. Optimizing the distribution structure and developing middle-income groups are conducive to enhancing the endogenous motivation of high-quality development and are a key link to smooth the national economic cycle. It is necessary to adhere to the principle that distribution according to work is the main body and various modes of distribution coexist, increase the proportion of labor remuneration in the initial distribution, solidly promote common prosperity, and continuously enhance the people’s sense of acquisition, happiness and security.

　　Firmly holding the bottom line of safe development is an important prerequisite and guarantee for building a new development pattern, and it is also the proper meaning in the problem of unblocking the domestic big cycle. The more open it is, the more attention should be paid to safety. We should coordinate the two major events of development and safety, enhance our own competitiveness, open supervision and risk prevention and control capabilities, and attach importance to the use of internationally accepted rules to safeguard national security. We must adhere to the overall concept of national security, grasp the relationship between openness and security, weave an open safety net, enhance our ability to dynamically safeguard national security in the environment of opening to the outside world, and promote people’s livelihood, social stability and order, and long-term national stability.

　　General Secretary of the Supreme Leader pointed out: "As China enters a new stage of development, reform is also facing new tasks, and we must take greater courage and take more measures to break down deep-seated institutional and institutional obstacles." Since the 18th National Congress of the Communist Party of China, we have launched a series of major reform measures around implementing the new development concept, promoting high-quality development and opening wider to the outside world, and formed a series of theoretical achievements, institutional achievements and practical achievements, which have made the construction of a new development pattern have obvious institutional advantages and a solid foundation for reform. We should pay more attention to deepening reform and opening up to enhance the endogenous motivation for development, be good at using reform thinking and methods, and make overall consideration of short-term response and medium-and long-term development. We should not only make a good strategic plan, but also make good decisions at key points, form an institutional mechanism conducive to the implementation of new development concepts, promote deeper reforms, and implement a higher level of opening up, thus providing a strong impetus for building a new development pattern.

　　(7) "It is just a hundred years of elegance to have great achievements in the future." The Communist Party of China (CPC) people are firm in their ideals and beliefs, keep in mind their original mission, take root in the people, and always remain full of vigor and high morale, and strive hard to achieve the goal of the second century and the great rejuvenation of the Chinese nation. The prospects are bright, and drums are used to urge the levy. Time and potential are on our side, which is our strength and confidence.

　　We have great confidence in forging ahead in the new journey. China’s development and progress has never been achieved in a calm, but with the courage of "the more difficult and dangerous it is, the more forward it is" and the enthusiasm of "opening roads on every mountain and bridging bridges when encountering water", it has been achieved in tackling difficulties and stepping over bumps. Today, with the strong leadership of the CPC Central Committee with the Supreme Leader as the core, the remarkable advantages of the Socialism with Chinese characteristics system, strong mobilization ability and comprehensive strength, super-large-scale market advantages and domestic demand potential, and huge human capital and human resources, we have all the more reason to believe that China has an extremely broad stage, a very deep foundation and a very strong kinetic energy, and will be on the track of high-quality development based on the new development stage, implementing the new development concept and building a new development pattern.

　　Striving for a new journey, we dare not be complacent. Those who walk a hundred miles are half-ninety, and the closer they are to the goal of national rejuvenation, the more they can’t slack off and the more they have to redouble their efforts. General Secretary of the Supreme Leader has repeatedly stressed: "Socialism is done, and the new era is fought." It should be noted that China’s economy is in the key period of transforming the development mode, optimizing the economic structure and transforming the growth momentum, and there are still many shortcomings and weaknesses in achieving high-quality development. We must never be hesitant, wait-and-see, lazy or weak, let alone sleep on the credit book. We must know how to bear heavy burdens, overcome difficulties and constantly enhance the courage and strength to forge ahead. We should also see that the world today is undergoing a great change that has never happened in a hundred years. A century-long change is not a one-time event, a change in one region and one country, but a change in the world, times and history. The epidemic situation has accelerated the evolution of the international pattern, and the pressure and challenges have increased under the "more external environment against the wind and water". We should have the wisdom to change, the ability to respond to changes, and the courage to change, unify seeking things with seeking the situation, seeking the present and seeking the future, adjust our strategies in time in response to the development and changes of the situation, and firmly grasp the initiative in development.

　　"Dapeng rises with the wind one day, soaring up to Wan Li." Building a new development pattern is an important strategic task related to China’s overall development, the only way to promote economic modernization, and the first move to grasp the initiative of development. On the new great journey, unite more closely around the CPC Central Committee with the Supreme Leader as the core, continue to be modest and prudent, guard against arrogance and rashness, continue to work hard and forge ahead with determination, mobilize all the positive factors that can be mobilized, unite all the forces that can be United, and do our best to do our own thing, and we will certainly be able to ensure a good start in building a socialist modern country in an all-round way and create a great historical cause that belongs to our generation!
