Recently, a controversy about Huang Lei’s cooking skills has been raging on the Internet, which has attracted the attention of netizens. It starts with Huang Lei’s performance in a variety show. As a permanent guest of the program, Huang Lei often cooks and prepares meals for other guests. However, with the popularity of the program, the audience’s evaluation of his cooking shows a polarized trend. Some people are full of praise, while others scoff.

Let’s talk about the background of the incident first. Huang Lei is a busy man in the program, not only to take care of the dietary needs of the guests, but also to ensure that every meal can make everyone happy. His cooking has also become a highlight of the show, and many viewers are coming for his cooking. But with the passage of time, everyone’s views began to differ.

Some people think that Huang Lei’s food is delicious in color, smell and taste. For example, Michael Chen once supported Huang Lei in the live broadcast, bluntly saying that it was "really delicious". But others don’t think so. They think Huang Lei’s cooking is mediocre, and some even make fun of the food poisoning incident in Song Dandan, implying that Huang Lei’s cooking is open to question. This polarized evaluation makes the whole thing more and more complicated.

So, what does Huang Lei himself think of these disputes? In an interview with reporters, Huang Lei said that he didn’t care about these public opinion storms. He said: "Just like the establishment of the so-called drama ecology, we are actually conveying some attitudes towards life related to art. The performance is actually a very small part of Wuzhen Drama Festival. I am the same. I have more important things to do. If those public opinions can entertain others, it is good. I just have to work hard and do things in good faith. "

Have to say, Huang Lei’s response is quite calm, I can see that he is very clear about his position and goals. However, this also reflects a phenomenon: in today’s social media environment, every move of public figures may become a hot topic. Whether it is praise or criticism, it may be infinitely magnified, affecting their image and reputation.

Social media has played a role in this process. On the one hand, it allows more people to participate in the discussion and express their views; On the other hand, it may also lead to information distortion and over-interpretation. For example, Huang Lei’s manual stirring of egg liquid and stir-frying of pot-wrapped meat with hawthorn were dubbed as "rollover highlights" by netizens, but in fact, whether these clips really represent his true level, I am afraid more understanding and judgment are needed.

In a word, this cooking dispute in Huang Lei has brought us some enlightenment. First of all, the situation of public figures in online public opinion is really delicate. They need to deal with all kinds of voices more carefully while maintaining their inner firmness. Secondly, we should also learn to discuss rationally and respect multiple viewpoints. After all, everyone’s tastes and preferences are different, and there is no need to rise to the level of personal attacks because of a small dispute.

Finally, as a senior self-media practitioner, I sincerely suggest that you must learn to use advanced productive forces and use AI every day. It has become my working habit to use AI to generate pictures of articles, which not only helps me greatly improve my work efficiency, but also brings more traffic to my articles.

CCTV News:According to the website of the US Navy Times, on April 8, local time, the first "Ford" of the newly developed "Ford" class aircraft carrier of the US military made its first self-powered voyage in Newport Port, and immediately began sea trials. So what is the difference between the latest aircraft carrier developed by the US military?

"Ford": Known as the world’s most advanced aircraft carrier

"Ford", 332 meters long and 40 meters wide, has a displacement of over 100,000 tons. It uses nuclear propulsion and has a speed of 30 knots. The number of carrier-based aircraft has reached more than 75, with a staffing of 4,550, and the total cost is as high as 13 billion US dollars.

　△ Figure/vision china

The overall dimensions of the "Ford" class aircraft carrier are not much different from those of the Nimitz class aircraft carrier (the active nuclear-powered multi-purpose aircraft carrier under the US Navy), but the performance has been significantly improved:

First, the degree of automation is further improved by using electromagnetic catapult instead of steam catapult and electromagnetic arresting device instead of hydraulic arresting device..

Second, the use of new nuclear reactors is more efficient..

Thirdly, it is possible to adopt a multi-functional phased array radar with single frequency band or a multi-functional radar with stronger anti-missile ability, so that the information level is higher.. 　

The sea trial of "Ford" will be carried out for several days, mainly focusing on the related tests of hull mechanical engineering and power system. After that, the US Navy will conduct flight operations and conduct a comprehensive test of the aircraft carrier’s flight deck.

　△ Figure/vision china

So, what is so outstanding about this so-called world’s most advanced aircraft carrier?Military expert Zhang Junshe believes that there are three main points.：

First of all, as the third-generation nuclear-powered aircraft carrier, Ford uses electromagnetic catapult, which has stronger ejection ability and more flexibility.You can eject a plane every 45 seconds25% faster than a Nimitz-class steam catapult. According to data research, Nimitz-class aircraft carrier can dispatch up to 160 carrier aircraft every day, and once electromagnetic catapult is used, the carrier aircraft dispatch of "Ford" aircraft carrier can reach 180.

Second, the power generation capacity is improved, which is three times higher than that of Nimitz-class aircraft carriers. The "Ford" aircraft carrier has two new and advanced nuclear reactors, each with a power generation capacity of 300 MW.In this way, we can meet the needs of using high-energy weapons such as rail gun and laser cannons in the future..

Thirdly, the setting on the deck is optimized. It will take time to finish the action of refueling and hanging bombs on carrier aircraft,From two hours to one hour..

Equipped with shipborne drones to subvert traditional operations

Another striking thing about the American "Ford" aircraft carrier is that it is equipped with an X-47B unmanned attack aircraft. It is the world’s first unmanned aerial vehicle that does not rely on manual remote control, but is independently controlled by artificial intelligence.

According to experts’ analysis, the X-47B unmanned attack aircraft has a long range and a large combat radius. Once it is put into operation, it can not only reduce casualties, but also carry out a deadly deep attack on the other side. Although the X-47B unmanned attack aircraft has many problems in the shipboard test, if it is used in conjunction with future manned fighters on the aircraft carrier, it will greatly improve the combat capability of the US Navy.

Military expert Zhang Jun society：

Former U.S. Defense Secretary Hagel once pointed out at the shangri-la dialogue Conference that once the X-47B unmanned attack aircraft successfully took off or landed on the aircraft carrier, it marked that the U.S. Navy entered a new aviation era, and it was also a milestone for the United States to gain military superiority.

Expert: The US military will rely more on aircraft carrier combat forces in the future.

In 2012, after the first nuclear-powered aircraft carrier Enterprise in the United States was retired, the US military has maintained a lineup of 10 Nimitz-class nuclear-powered aircraft carriers. After Trump took office, he put forward the slogan of restoring the number of aircraft carriers to 12. What does the joining of "Ford" mean to the US military?

Zhang Junshe, a military expert, believes that the main purpose of increasing the number of ships from the current 10 to 12 is to maintain the absolute superiority of the US Navy, especially compared with other countries. At present, the aircraft carriers owned by some countries in the world are much worse than the Nimitz-class aircraft carriers in the United States in terms of tonnage, the number of carrier-based aircraft and combat strength. In this case,The United States continues to develop aircraft carriers, of course, indicating that it will rely more on aircraft carrier combat forces in the future..

1905 movie network news As the opening work of the "New Culture" series, the film explores the theme and expression of the beauty of traditional culture with the audience through poetry, which is deeply loved by the audience. It not only won over 1.6 billion box office, but also became the second box office of the animated film in China.

In order to thank the audience for their enthusiasm and better explore Li Bai’s ideal journey of "Three Wan Li", on August 5th, the film director, producer Song Yiyi and voice actor Cheng Jianjun entered Ezhou with the theme of "Everyone in the world knows the monarch".

"It’s a quiet night in the south building, and it’s romantic in Wuchang". Ezhou, known as Wuchang in ancient times, has given Li Bai infinite pride and creative inspiration thousands of years ago because of its rich historical background and vast natural landscape near the river, and his literary ink has become a "cultural gene" that Ezhou people are proud of and passed down from generation to generation. Therefore, to love and recite poems is both a culture and a life for the people of Ezhou.

On the morning of the 5th, the film’s main creator was in Wuchang Building, Xishan, and held a "Hundred people chanting and flashing" activity together with Ezhou primary and secondary school students and citizen representatives. Li Bai’s famous piece "Going into the wine" and "Drinking with Song Zhongcheng in Wuchang at night" read neatly and sweetly, and went away with Jiang Feng.

Even though the weather was hot, such a scene still shocked director Xie Junwei: "Today in Ezhou, I really felt what outstanding people are. The outstanding people are the lake scenery and mountains overlooking, which made me understand the feelings of the millennial poets. The outstanding people are the children who read poems together. Their concentration and seriousness made me feel the spirit of Chinese culture, which is exactly what our film wants to express and hope to inherit."

Zou Jing, the director, also felt unfinished: "When I came to Ezhou, I was very moved to hear everyone recite Li Bai’s poems together. We made this movie just to follow the footsteps of the sages and feel what they saw, heard, thought and felt. I saw all this in Ezhou today, especially when I stood on the upper floor of Wuchang and looked at the Yangtze River, before I understood what’ the lonely sail is far away and the blue sky is exhausted’, but perhaps not everyone can have the opportunity to experience it on the spot. I am very happy to present poetry and grandeur to everyone with animation, a free and imaginative creative way that we are good at. "

After the flash mob, the creators immediately rushed to the cinema to meet and interact with the audience. At the opening ceremony, the film "The Same Style" of the founders deeply attracted the attention of the audience. Song Yiyi, the producer, gave a detailed introduction to the knowledge about the fork-hand ceremony, and his serious and rigorous creative attitude won unanimous praise from the audience. The salute on stage and off stage is a mutual thank-you, a common tribute, a tribute to traditional culture and a tribute to beautiful rivers and mountains.

Enthusiastic Ezhou audience not only actively interacted with the main creator around the film content, asked questions and dispelled doubts, but also made "eighteen martial arts". Several friends, big and small, voiced the film clips on the spot, and their dubbing skills and understanding of the characters were praised by Cheng Jianjun’s dubbing actor Lu Lifeng. As an important role throughout the film, Lu Lifeng shared the feeling of tension with the old Gao Shi dubbing actor’s teacher, and also revealed the interesting story of the two directors showing new "voices" in the film and participating in dubbing.

　　"I have deep feelings for the mountains and rivers, the grass and the trees here. After I left Fujian, I have been paying attention to Fujian. Some thoughts and explorations during my work here are still being thought about and deepened in my later work, and some have been practiced on a larger scale in the country. " Comrade Supreme Leader worked in Fujian for 17 and a half years, creatively put forward a series of important ideas and promoted a series of major practices. The general secretary has always been concerned about the mountains, rivers and villagers in Bamin.

　　Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has made many important instructions on Fujian’s development. When he went to Fujian for investigation in November 2014, the general secretary drew a grand blueprint for Fujian to build a new Fujian with flexible mechanism, excellent industry, rich people and ecological beauty. When he visited Fujian in March 2021, the General Secretary asked Fujian to "make greater progress in accelerating the construction of a modern economic system, show greater achievements in service and integration into the new development pattern, take greater steps in exploring a new road of cross-strait integration and development, achieve greater breakthroughs in creating a high-quality life, and strive to write a chapter on building a socialist modern country in Fujian in an all-round way."

　　The sons and daughters of Bamin remember the entrustment, vigorously carry forward the spirit of "Dare to be the first, love to fight and win", work hard and bravely, push forward high-quality development in all directions, and strive to write a chapter on building a socialist modern country in Fujian.

　　The dribs and drabs of exploration and practice are the epitome of the magnificent times. Just as the supreme leader comrade wrote a poem when he was working in Fujian: "Hold Yun He to wash the sky, and the mountains and waters in Fujian are new."

　　Mechanism activity — —

　　Give impetus to reform and opening up.

　　Shaxian District, Sanming City, the garage is green outside the window. The lush forest sea witnessed a profound change that lasted for 20 years.

　　When the Supreme Leader worked in Fujian, he promoted the reform of collective forest right system. Shaxian county is one of the sources of forest reform.

　　On March 23, 2021, General Secretary of the Supreme Leader came to Shaxian Rural Property Rights Exchange Center for investigation. At that time, Zhang Zuwen, a forester in Xinpo Village, Gao Qiao Town, was going through the formalities of forest land transfer. "The general secretary learned about the transfer of collective forest land management rights and real estate registration from our people and staff." Recalling the scene at that time, Zhang Zuwen still remembers it.

　　During the inspection, the general secretary pointed out that the exploration of collective forest right system reform in Sanming is of great significance. We should adhere to the correct direction of reform, respect the initiative of the masses, actively and steadily promote the innovation of collective forest right system, explore and improve the mechanism for realizing the value of ecological products, and strive to achieve new breakthroughs.

　　Bearing in mind the entrustment of the General Secretary, Sanming City issued an action plan in September 2021 to promote the implementation of eight innovations, including forestry financial mechanism, forest ticket system and forestry carbon ticket system, and promote the forest reform.

　　Zhang Zuwen took advantage of the trend and cooperated with the local state-owned forest farm to build a "carbon neutral" demonstration forest. The forest farm was responsible for the whole process management, and the income was distributed in shares. "The same mu of forest, single-family single-family management has at most 6 to 8 cubic meters of output, and forest farm management can be improved several times!" Zhang Zuwen is full of feelings.

　　From the implementation of the new model of specialized joint venture, the solution of "how to deal with single-family households", to the implementation of forestry financial innovations such as forest coupons and carbon coupons, and the breakthrough of the single path of realizing forestry resources, Sanming forest reform has advanced in depth, allowing many forest farmers to enjoy the reform dividend like Zhang Zuwen. In 2021, the total forestry output value of Sanming City reached 121 billion yuan, driving the per capita disposable income of rural residents to increase by 10.7%, of which the per capita net forest-related income accounted for 30.6% of the disposable income.

　　On March 10, 2019, when attending the deliberation of the Fujian delegation of the Second Session of the 13th National People’s Congress, the Supreme Leader General Secretary emphasized: "We should give impetus to reform and opening up, release the kinetic energy of innovation and entrepreneurship in the whole society to the maximum extent, and continuously enhance China’s influence and competitiveness in the great changes in the world." "We should give full play to the overlapping advantages of special economic zones, free trade pilot zones, comprehensive experimental zones, and the core area of the 21st Century Maritime Silk Road, constantly explore new ways, attract high-quality production factors to concentrate, comprehensively enhance Fujian’s industrial competitiveness, and strive to take the lead in building a new open economic system."

　　Carrying out the spirit of the important instructions of the General Secretary, Fujian has made good use of multi-zone overlapping policies such as special economic zones, pilot free trade zones, and the core area of the 21st Century Maritime Silk Road, and promoted deeper reform and higher level opening around services and integration into the new development pattern — —

　　Not long ago, Xia Ning, the head of Huaguang Biotechnology (Pingtan) Co., Ltd., found that the company account was suddenly transferred to 100,000 yuan. It turns out that industrial enterprises that are promoted from below the scale to above the scale for the first time can receive a reward of 100,000 yuan from the government. Enterprises do not need to apply and submit materials, and they are "rewarded by triggering". "Enjoy the policy of benefiting enterprises, before ‘ People look for policies ’ , now ‘ Policy to find someone ’ , quick cash, warm heart! " Xia Ning said with emotion.

　　Gather departmental data, and the government actively collects application materials — — The new model of Pingtan Comprehensive Experimental Zone, which is "free of application and immediate reward", makes good use of modern information technology and optimizes the landing mechanism of the policy of benefiting enterprises.

　　From the "one network to run" to the "one thing to do" integrated package service reform, Fujian has combined the "streamline administration, delegate power, strengthen regulation and improve services" reform with the construction of digital Fujian to strengthen digital empowerment and optimize the business environment. In 2021, the proportion of government affairs services in Fujian province will reach 80.4%, and the proportion of "one trip without running" will reach 90.3%.

　　In the joint inspection hall of Xiamen Port, few people pay attention to the customs declaration window that used to be crowded with people. "In the past, customs declarations were made in multiple windows, multiple acceptances, and multiple declarations. Now, data runs, one platform, and one settlement can be completed in three or five minutes." Having been in charge of customs declaration for many years, Fang Shuyu, manager of the document examination department of Xiamen Foreign Customs Broker Co., Ltd., witnessed the iterative upgrade of the "single window" reform in Xiamen area of Fujian Pilot Free Trade Zone.

　　From the establishment of a "single window" for international trade to the first implementation of the "three certificates in one, one photo and one yard" registration model, Fujian Pilot Free Trade Zone has made bold attempts, made bold breakthroughs and made independent reforms, and strived to build an institutional system and supervision model that is in line with international common rules. It has successively launched 508 innovative measures, with 111 being the first in China.

　　New steps have been taken in reform and opening up to help Fujian build an important node and an important channel for domestic and international double circulation, promote more high-quality elements to gather in Fujian, and let more products and services go from Fujian to the whole country and the world. In 2021, the actual use of foreign capital in Fujian increased by 6.1% year-on-year, and its export increased by 27.7%. The export scale exceeded 1 trillion yuan for the first time.

　　Industrial Excellence — —

　　Make greater progress in accelerating the construction of a modern economic system.

　　"After I went to work in the province, I made many investigations in Jinjiang, and the whole province promoted ‘ Jinjiang experience ’ . If there are several Jinjiang rivers in Fujian Province, Fujian will be different. It should be said that ‘ Jinjiang experience ’ It still has guiding significance. " In March 2019, General Secretary of the Supreme Leader pointed out during the deliberation of the Fujian delegation at the Second Session of the 13th National People’s Congress.

　　Neikeng Town, Jinjiang City, Fujian Hengan Household Articles Co., Ltd.. The robot arm in the "black light warehouse" is doing palletizing work in an orderly way. In this three-dimensional warehouse with a capacity of four times that of the traditional warehouse, the packaging, transportation and delivery of finished products are all arranged by the intelligent system, and workers can easily load tons of raw materials through the control panel.

　　Since its establishment 37 years ago, Hengan Group has been focused on innovation and has developed from a small township factory to one of the largest household goods enterprises in China. In 2021, Hengan Group achieved an operating income of 21 billion yuan, and its leading products such as baby diapers and household paper remained in the forefront of the domestic market.

　　Jinjiang has always kept a close eye on the real economy and made great efforts to promote the transformation and upgrading of the manufacturing industry. In Jinjiang 20 years ago, there were only 55 enterprises with an output value of over 100 million yuan, and now there are 1165 enterprises. Last year, the output value of industrial enterprises above designated size in Jinjiang exceeded 690 billion yuan. The four traditional industries of Jinjiang, such as shoes, clothing and textiles, continue to have advantages, with an industrial output value of nearly 530 billion yuan last year. Three emerging industries, such as a new generation of information technology and intelligent manufacturing equipment, are also "accelerating gear shifting". Last year, the industrial output value exceeded 78 billion yuan.

　　Unswervingly developing the real economy is the most distinctive feature of "Jinjiang Experience". Fujian inherits and carries forward the "Jinjiang experience", makes the manufacturing industry bigger, stronger and better, and constantly builds a solid foundation for the modern economic system. In 2021, the added value of industrial enterprises above designated size in Fujian increased by 9.9% year-on-year, and there were 21 industrial clusters with output value exceeding 100 billion yuan.

　　Fujian Fuguang Co., Ltd. has a wall full of invention patents. "To overcome difficulties in building the world’s largest refractive telescope", a line of slogans in the exhibition hall is very eye-catching.

　　“‘ Fourteenth Five-Year Plan ’ At that time, our country must rely on innovation to move forward. It’s no good following the crowd all the time. Now it depends on who can seize the opportunity, who has such a sense of responsibility and mission, and who has the ability to do it well. Grasp innovation and don’t ask ‘ Origin ’ As long as it can contribute to the country, the country will fully support it. Whoever can do well is the pillar of the country’s heroes. " On March 24, 2021, General Secretary of the Supreme Leader emphasized when inspecting Fuguang Company.

　　"The words of the general secretary make us more motivated." He Wenbo, chairman of Fuguang Company, said. From a one-meter refractive astronomical telescope with a large field of view to a large-caliber catadioptric 10K ultra-high definition astronomical telescope … … For more than a year, this important global manufacturer of optical lenses has never stopped.

　　Taking out two high-definition photos of Mars, He Wenbo said proudly: "‘ Tianwen-1 ’ Many sets of optical systems and lenses carried on the plane are provided by Fuguang. "

　　In March 2021, General Secretary of the Supreme Leader proposed during his inspection tour in Fujian that "greater progress should be made in accelerating the construction of a modern economic system". Fujian keeps in mind the entrustment, excellent platform, strong subject, gathering talents and flexible mechanism, accelerates the implementation of innovation-driven development strategy, accelerates the construction of advanced manufacturing provinces and innovative provinces, and promotes the optimization and upgrading of the economic system. In 2021, the added value of high-tech industries in Fujian Province increased by 26.4%, and the number of new high-tech enterprises exceeded 2,400.

　　Digital economy is an important engine for building a modern economic system. As early as 2000, when the supreme leader was working in Fujian, he had an insight into the development trend of information technology and made arrangements for building a digital Fujian. In March, 2021, General Secretary of the Supreme Leader exhorted: "Optimize and upgrade the industrial structure, and accelerate the promotion of digital industrialization and industrial digitalization".

　　At the Beijing Winter Olympics and Paralympic Winter Games, digital RMB brought different payment experiences to athletes and spectators. Seven kinds of scene applications, such as eating, traveling, shopping and traveling, were deeply involved by Fuzhou-based New World Technology Group Co., Ltd. "At present, the New World is actively cooperating with the digital currency Institute of the People’s Bank of China and major commercial banks to carry out the pilot development of digital RMB." Jing Wong, CEO of the Group, said.

　　Up to now, more than 50,000 enterprises in Fujian have been on the cloud platform. In 2021, the added value of Fujian’s digital economy reached 2.3 trillion yuan, an increase of 15%, accounting for about 47% of the province’s GDP.

　　People are rich — —

　　Achieve greater breakthroughs in creating a high-quality life

　　After the rain, Chixi Village, with white walls and tiles, has a unique charm.

　　More than six years ago, a video connection made this small mountain village in the mountains of eastern Fujian boil. On February 19, 2016, the General Secretary of the Supreme Leader came to the People’s Daily Studio to connect with the People’s Daily reporter through video and communicate with the villagers in Chixi Village, Ningde City, Fujian Province. The general secretary said hello to the villagers, telling them to protect the green mountains and green rivers and embark on a path of green development and ecological enrichment.

　　White tea, tourism and mushroom, the ecological road to enriching the people in Chixi Village is getting wider and wider. "After getting rid of poverty, we want to report more good news of rural revitalization to the general secretary!" Wu Yiguo, secretary of the Party branch of Chixi Village, said that the per capita disposable income of the village reached 32,200 yuan last year.

　　In November, 2014, General Secretary of the Supreme Leader pointed out that there are many mountainous areas and old liberated areas in Fujian. In those days, people in the old liberated areas in the Soviet area sacrificed their lives for the revolution and the establishment of the new China. Today, some of these areas are still relatively poor. We must speed up scientific and accurate poverty alleviation through leadership contact, mountain-sea cooperation and counterpart assistance, do a good job in education, employment, medical care, social security and other livelihood issues, and support and help poor areas and poor people to get rid of poverty as soon as possible and become rich and well-off.

　　Fujian carries forward the spirit of weak birds flying first and dripping water wears away the stone, and makes great efforts to get rid of poverty. Together with the whole country, Fujian has completely eliminated absolute poverty.

　　In early summer, I entered the old revolutionary base villages — — In the snack street of Yubang Village, Xiamao Town, Shaxian District, thick smoke and fire came on, and tourists from all over the world tasted delicious Shaxian snacks.

　　On March 23, 2021, the villagers in Yubang Village listened to the inspiring words of the General Secretary: "Shaxian people traveled south and north, making Shaxian snacks a characteristic industry for enriching the people. To revitalize the countryside, it is the key to choose industries that enrich the people according to local conditions. We must seize the opportunity, broaden our horizons, adapt to market demand, continue to explore and innovate, and take the lead in creating a new journey of a better life. "

　　Over the past year or so, the development of Yubang Village has been gratifying: Shaxian snacks have moved towards standardization and industrialization, snack street has become online celebrity, old houses have become new houses, and the integration of literature and tourism is booming & HELIP; … Yu He, a 71-year-old snack owner, said: "When making snacks, Yu Bangcun took the lead; Now, to create a new journey of a better life, we have to ‘ Leading the way again ’ ！”

　　Shaxian snack has developed into a big industry that benefits the people in the old Shaxian area, with an annual turnover of about 50 billion yuan and more than 300,000 people employed by radiation.

　　Although the community is small, it is connected with thousands of households. In November 2014, General Secretary of the Supreme Leader entered the Junmen Community in Gulou District, Fuzhou. The General Secretary pointed out that community party organizations and party member cadres should think more about how to make people’s life and work more convenient, how to make the channels for people to express their demands more smooth, how to make people feel safer and happier, and really make thousands of families feel the warmth of the party and the government.

　　The earnest entrustment of "Three How’s" is deeply imprinted in the heart of Lin Dan, secretary of the Party Committee of Junmen Community. Over the years, the Junmen community, guided by Party building, has continuously innovated the community governance model to make the residents more convenient, safer and happier. The "13335" work law of the military community, which was independently explored, was promoted nationwide by the Ministry of Civil Affairs.

　　Bearing in mind the important directive requirement of "making greater breakthroughs in creating a high-quality life" put forward by the General Secretary during his inspection in Fujian, Fujian adheres to the people-centered development idea and effectively guarantees and improves people’s livelihood: building a healthy Fujian, Sanming’s medical reform experience is promoted throughout the country; Every year, more than 70% of the province’s fiscal expenditure is invested in the people’s livelihood field … … In 2021, the per capita disposable income of urban and rural residents in Fujian increased by 8.4% and 11.2% respectively, and the ratio of per capita disposable income of urban and rural residents was 2.20, which was 0.06 lower than the previous year.

　　Ecological beauty — —

　　Let green water and green hills always be the pride of Fujian.

　　Wuyishan National Park Wisdom Management Center, on the blue wisdom screen, summarizes all kinds of monitoring data of national parks in real time. Fan Zhiwei, a staff member, sat in front of the operation desk and clicked the mouse. Animals and plants such as yellow-bellied pheasant, black bear, silver pheasant and yew appeared in the patrol lens from time to time.

　　On March 22, 2021, General Secretary of the Supreme Leader came here to see the vast "green ocean" through the big screen. The general secretary pointed out that the purpose of establishing a nature reserve system with national parks as the main body is to maintain the authenticity and integrity of the natural ecosystem and protect biodiversity in accordance with the concept that mountains, rivers, fields, lakes and grasses are a life community.

　　Since the pilot national park system, under the all-round and all-weather monitoring and management of "heaven, earth and air", the species "big family" in Wuyishan has been constantly adding new members. "At the beginning of this year, the phased results of the background investigation of biological resources were announced to the public, and six new species, such as Wuyi Rana, were discovered for the first time." Fan Zhiwei said.

　　Ecology, the Supreme Leader General Secretary called it "one of my most important things". In 1997, when the Supreme Leader visited Changkou Village in Sanming, he pointed out: "Green mountains and green waters are priceless, and the mountains should be painted well ‘ Landscape painting ’ Do a good job in landscape field articles. " In 2000, the supreme leader comrade took the lead in putting forward the strategic concept of building an ecological province. Subsequently, the leading group for the construction of Fujian ecological province was established, and the supreme leader comrade served as the leader of the leading group.

　　Draw a blueprint to the end, continue to implement the strategy of building an ecological province, and "Fresh Fujian" has become a beautiful business card. During the "Thirteenth Five-Year Plan" period, the proportion of excellent air days in cities with districts in Fujian reached 98.8%, and the proportion of excellent water quality in major river basins reached 97.9%. At present, Fujian’s forest coverage rate has reached 66.8%, which has been leading the country for many years.

　　"In recent years, Fujian has become more lush. Green is a beautiful business card in Fujian. We must continue to work hard to make green mountains and green mountains always the pride of Fujian. " General Secretary of the Supreme Leader said during an inspection tour in Fujian in March 2021.

　　On May 26th this year, in Lianhu Village, Yutian Town, Changting County, Longyan City, the villagers Ma Xuemei couldn’t sit still after several days of rain. When she turned to the navel orange field, her hanging heart fell to the ground: "The rain is seeping into the soil, and it is not the same as running soil, running water and running fat."

　　Changting was once one of the areas with the most serious soil erosion in the red soil region of southern China. The supreme leader comrades have visited Changting for investigation five times and given instructions many times, personally caring for, guiding and promoting the soil erosion control work in Changting. In March, 2021, General Secretary of the Supreme Leader once again mentioned Changting during his inspection tour in Fujian: "I told you that investing money in ecology seems to be different from raising chickens and laying eggs like development and construction, but this matter must be grasped. In the end, I raised a golden rooster and gave birth to golden eggs. "

　　"A drop of water wears away a stone, and one person makes me ten", "If you advance, you will win; if you don’t advance, you will retreat" … … Adhere to the leadership of the party, work one after another, and make contributions for a long time. The green hills are full of legends, and Changting soil erosion control has become a typical example of global ecological restoration.

　　People live up to the castle peak, and the castle peak will live up to people. In the ravine, more than 7,000 navel orange saplings of Ma Xuemei’s family are half a meter high and are expected to bear fruit next year. She calculated the account. "Navel orange trees alone can earn 700,000 yuan a year."

　　As the first national ecological civilization experimental zone in China, Fujian has tried first and explored boldly, and basically built a complete system of ecological civilization system with clear property rights, diversified participation, equal emphasis on incentives and constraints, and 39 reform measures and experiences have been replicated and promoted throughout the country.

　　"The General Secretary of the Supreme Leader’s series of important instructions and requirements for Fujian’s work are consistent in thought, advancing with the times in goals, and deepening in requirements step by step. As a whole, they constitute the general compliance, general program and general blueprint for Fujian’s development. We must study and implement it comprehensively, accurately and systematically to ensure that the decision-making arrangements of the CPC Central Committee take root and bear fruit in Fujian. " The main responsible comrades of the Fujian Provincial Party Committee said.

　　　　I believe that card friends are no strangers to the "wind resistance coefficient". When the vehicle is driving at a low speed, the resistance mainly comes from the friction between the tire and the ground. When it reaches a certain speed, for example, when the speed exceeds 110km/h, about 70% of the resistance of the vehicle comes from the impact of airflow, which is what we often call air resistance. The magnitude of resistance is generally measured by wind resistance coefficient. The drag coefficient of our common cars is mainly between 0.28 and 0.4, so how to design the body shape and chassis to achieve the most reasonable drag coefficient has become one of the biggest problems faced by many car companies.

　　　　For family cars, low drag coefficient is particularly important, because it directly affects the fuel consumption and noise level of vehicles at high speed. Therefore, sometimes even the performance and appearance of some vehicles are sacrificed in pursuit of lower drag coefficient.

　　　　So how is the drag coefficient measured? After all, we can’t consider the data published by car companies, especially the "illusory" data like drag coefficient. To this end, we came to the Shanghai Ground Vehicle Wind Tunnel Center in Jiading Campus of Tongji University in Shanghai to reveal the whole process of this experiment. The brand-new 7-seat MPV Auchan of Changan is our test vehicle. Judging from the officially announced drag coefficient of 0.334, it is definitely at the top level in the same class, even far exceeding some joint venture brands.

　　　　Shanghai Ground Vehicle Wind Tunnel Center can be said to be the most advanced vehicle wind tunnel center in China, which cost 500 million yuan to build and has been tested by hundreds of enterprises. I have to ridicule here that it is absolutely extravagant to "blow the wind" in the experimental room. According to the staff, their charging standard is in minutes, and it takes 400 yuan RMB to blow for one minute. Under normal circumstances, it takes nearly 8 hours for a car to complete all the test processes, and the total cost is about 250,000 to 300,000 yuan. Of course, this has not calculated other additional costs such as transportation and labor. Normally, a new car needs to do three wind tunnel tests, and through the process of improvement and retest, it can reach the most perfect state.

　　　　We should know that not all car companies will choose wind tunnel test when developing new models, and some of them will use computer simulation to simulate the test process. Although the cost is relatively low, the accuracy of the measured data remains to be discussed.

　　　　Changan Automobile is not "spending money like water". They reasonably combine the two testing methods. In the early development, they used computer simulation technology to improve the design of the body and chassis as much as possible to achieve lower drag coefficient and quiet cabin space. In the final stage, the real wind tunnel test was used to improve the shortcomings of the vehicle and improve it. It can also be seen that Changan Automobile has invested heavily in this brand-new home MPV and has high expectations.

　　　　Through this reasonable development process, the drag coefficient of Auchan finally reached 0.334. Because of the demand of interior space, this MPV model can not achieve the streamlined structure like a car, so it is necessary to make up for its disadvantages as much as possible through scientific treatment of some details. Because the positioning of MPV models is completely family-oriented, who can achieve lower fuel consumption and noise while ensuring space can be more popular.

Chat for a while before going to bed. There is a world in my dream. Hello, everyone. At the invitation of Party newspaper critic Jun, today we will talk about movies. In the past few days, a domestic film has been "on fire" quickly. From the beginning of the screening, it received rave reviews and the box office surged. Douban scored 9.0, and the cumulative box office on the opening day broke 300 million, which was widely praised by people inside and outside the industry and had the potential of "explosion". Speaking of which, you may have guessed the name of this movie-Dying to Survive. Yes, today we will talk about it.

To evaluate the success of a cinema film, the simplest criterion is to see whether it is "applauded and popular". "Applauding" shows that the film is of high quality, thoughtful and unforgettable; "Making a seat" shows that the market is highly recognized and it is a good story that everyone generally agrees and is interested in. According to the box office data posted on the opening day, Dying to Survive reached 18 million box office in 10 hours, and the box office exceeded 100 million in a single day. There is a great potential for the subsequent box office growth, and the "box office" has already become obvious, only which number is finally fixed. What really deserves our attention is why this film is "applauded" and what kind of audience expectations are hidden behind this voice.

To a large extent, this is a complicated film. In the first half of the film, many social themes are wrapped in the shell of comedy. The process of Cheng Yong’s "calling" teammates, played by Xú Zhēng, has brought out many kinds of life, including young people in small towns who left home because of illness, middle-class urban people who aroused their hope for survival because of their children, a huge group of patients who exchanged information by QQ, fake academicians who sold fake drugs, mercenary international companies and even bustling street scenes in India. Medicine, like a prism, reflects a world and life that we have heard but not necessarily seen, seen but not necessarily experienced.

In the second half of the film, the development of characters is wrapped in a more lyrical atmosphere. Cheng Yong, who changed his hairstyle, experienced the touch and torture of his heart again and again. The past experiences, like seeds, gradually grew into a big tree in his heart. Stripped of the element of "interest", the film makes people think more about the relationship between themselves and others, between individuals and society, between reason and jurisprudence, and experiences spiritual growth with the protagonist. This content, which pays more attention to inner pursuit, has also made the film more open: it is in this dialogue that individuals can get a more open and calm life, and society can be improved and improved through everyone’s efforts.

It’s more than that. What the film catches people is that it creates a group of characters who love life and strive to live. The characters in the film have a hard life because of illness. But the reason why people are great is the determination not to give up easily in the face of bumps and tribulations. That will to survive and optimistic attitude, like a key, found the shocking keyhole of the film. In the film, what the sick grandmother said to the police was the highlight of the film-"I don’t want to die, I want to live". If it is extremely simple, it is full of sad but persistent life force, and this force is full of people’s truest longing for life. In the poster of the film, except Cheng Yong and Liu Sihui, all the people are haggard and haggard, and some people still have masks on their faces, because these people are leukemia patients. But if you pay attention to their expressions, you will find that they are all smiling, even if they are weak or tired, because they "want to live" and "don’t want to die". It is precisely because of this idea that Cheng Yonggan is willing to take the risk of breaking the law and take medicine overseas. Because his idea is simple-although these people are in trouble, they have the desire and belief to live, and it is a little bit that they can do it themselves.

Since last year, Indian movies such as Wrestling Dad, Toilet Revolution and Mysterious Superstar have made China audiences feel how movies can cut into society and life, and they are eager to see a similar domestic movie. The appearance of Dying to Survive undoubtedly complied with the expectations of the audience and the market. Compared with the popcorn works of popular IP, such as fantasy overhead, little affection and little love, a work that touches people’s hearts and knows human nature, a work that is rooted in reality and truly finds a fresh theme that is deeply rooted in people’s hearts and reflects life, undoubtedly has stronger vitality.

Perhaps, we can review a passage like this: "Literature and art are deeply integrated into people’s lives, and all aspects of human life can be inspired by literary and artistic works, including career and life, prosperity and adversity, dreams and expectations, love and hate, existence and death." Similarly, all aspects of human life should also become fertile ground for literature and art, so as to leave a truly "bone-bound, moral and temperature" work.

This is exactly: I am not a drug god, you and I are all human. Based on the realistic road, "domestic" has roots. (People’s Daily Central Kitchen Siliao Studio Wang Zixiao)

　　(Reporter Fei Shiting) Resolutely safeguarding national security is the sacred mission entrusted by the party and the state to the people’s army. Today, with the complicated situation and arduous tasks, how can the people’s army focus on the characteristics and laws of modern military development and focus all its work on winning the battle? Over the past few days, deputies to the people’s congresses of the armed forces have held heated discussions on realizing the Party’s goal of strengthening the armed forces under the new situation and implementing intensive and efficient strategic guidance.

　　Challenges abound, and reality calls for a new model of development.

　　Why should we use intensive efficiency to guide the development and construction of national defense and the army? Representative Rong Guiqing, deputy commander and chief of staff of the Western Theater, said three practical needs in one breath:

　　The needs of the information age — — In the information age, the army shoulders the historical responsibility of building an information-based army and winning an information-based war. The construction and development can’t rely on quantity and scale, let alone extensive development. We must highlight quality and efficiency and take the road of intensive and efficient development.

　　The needs of the new military revolution — — At present, the world’s new military revolution is accelerating and the evolution of war forms is accelerating. Modern warfare is a confrontation between systems. System confrontation requires the organic unity of all elements, platforms and systems, and seeks the optimal effect. It is an inevitable choice to do a good job in joint operations and joint training based on the information network system, which is intensive and efficient.

　　The need to deepen national defense and military reform — — With the deepening of national defense and army reform, our army’s organizational structure and strength system are becoming increasingly complex, and the professional division of labor is more refined, which puts forward higher requirements for the internal management of various services, departments and troops. We must consider the overall situation of national defense and army development, further optimize the allocation and implement scientific management.

　　The problem is the voice of the times. Deputies to the People’s Congress of the PLA believe that a series of practical problems existing in the current military construction and development also urgently need to be solved through intensive and efficient methods. For example, for a long time, some troops have paid more attention to qualitative analysis, less quantitative analysis and less meticulous work. For example, some work operation mechanisms are unscientific, and the concept of grasping implementation is backward. Instead of grasping implementation, meetings, speeches and documents are used, and the process control of grasping work is not paid attention to, which is arbitrary and the effect is not obvious. For another example, it is difficult to coordinate among various services, departments and units. The coordination and coordination of various resources allocation is not enough, and the amount of resources invested is lack of standards and science.

　　"Intensive and efficient is the basic feature of the development of the modern army, the only way for the development of the modern army, and the symbol of a new model for the development of the modern army. We must profoundly grasp its scientific connotation and spiritual essence, take the initiative to adapt and adapt as soon as possible, and can’t wait. We must take a step early and take a big step." Deputy Li Tingwei, assistant engineer of Guizhou Military Command, said.

　　Emancipate the mind and firmly establish a new concept of development

　　Talking about the idea of intensive and efficient thinking, representative Chen Zhou, a researcher at the Military Strategy Research Department of the Academy of Military Sciences, told the story of "MIG -25".

　　"MiG -25" was once a miracle fighter, setting world records of flying speed and flying altitude for many times. At that time, people wanted to know, what created such a miracle? In the 1970s, an unexpected event unveiled its mystery for the world.

　　Military technical experts who have been speculating about MIG -25 have found that the reason for giving it superb skills is not that it has opened up any new technical fields, nor that it has adopted any outstanding technical achievements, but that it has successfully utilized the overall functional principle of system theory and effectively combined many components that are not the most advanced, thus producing amazing system effects.

　　"After all, ‘ MiG -25’ It is a practitioner of system theory: a powerful combat system is formed with relatively simple parts and electronic components. " Deputy Chen Zhou said: compared with the world’s military powers, the construction and development of our army started late, with a low starting point, and the reality that various resources are insufficient and in short supply is inevitable in the short term. The enlightenment brought by MIG -25 is that the reorganization of existing elements may be a new growth point of combat effectiveness. Therefore, we should emancipate our minds, update our concepts, coordinate the construction and development of national defense and the army with systematic and interrelated viewpoints, and further firmly establish an intensive and efficient thinking concept.

　　The adjustment and reform of the military system is also an embodiment of intensive and efficient. Deputy Si Qifu, former deputy director of the Equipment Department of the Jiangsu Military Region, said: the reform of the leadership and command system, which is being steadily promoted now, and the reform of the military scale structure that will be launched soon all focus on the characteristics and laws of modern warfare and the development trend of modern military system establishment, and strive to improve the combat capability, mobility and viability of the army on the battlefield, so as to improve the overall combat capability through restructuring and reshaping the system structure.

　　Deputy Chen Honghai, former commander of the Jilin Military Region, said that the reorganization of people and weapons and equipment is also the proper meaning of intensive and efficient problems. High-tech weapons and equipment need high-tech and new-type talents to adapt to it. They should be rationally diverted and chosen according to their specialties, qualities and abilities, so that people can make the best use of their talents, find a breakthrough in "combination", work hard on "running-in", seek the best model through restructuring, and promote the improvement of combat effectiveness.

　　Talking about the connotation of intensive and efficient, representative Rong Guiqing summarized it into seven key words: accuracy, science, standardization, order, strictness, economy and efficiency.

　　"Intensive and efficient is both a concept and a method." Deputies to the People’s Congress of the PLA called for further emancipating the mind, changing ideas, really having a "brainstorming" and firmly establishing a new concept of modern military development.

　　Precise policy, scientific construction of new development mechanism

　　The way to be in power is to worry about having no policy, and even more afraid of having a policy and not being true. Representative Gao Chao, deputy chief of staff of the Northern Theater, said: to fully implement the concept of intensive and efficient development, the core is to take the goal of strengthening the army as the traction, allocate all manpower, material resources and financial resources with a view to winning the battle, make efforts to solve the institutional obstacles, structural contradictions and policy problems that restrict national defense and army building, promote the modernization of army organizational forms, further liberate and develop combat effectiveness, and further enhance the vitality of the army.

　　At present and in the future, the task of deepening the reform of national defense and the army is arduous, and there are many new situations, problems and contradictions. Deputy Lu Shengjun, a political commissar of a former General Staff Department, said that it is necessary to aim at the word "precision", accurately plan, accurately plan, accurately implement and accurately test, and scientifically build a new mechanism for modern military development.

　　During the discussion, the military deputies to the National People’s Congress put forward a series of suggestions: perfecting and improving decision-making methods and procedures, implementing democratic and scientific decision-making; Quantitative analysis and fine analysis should be carried out; We should boldly use scientific and technological means to assist decision-making and implement scientific management; It is necessary to strengthen execution, pay attention to process control, and establish and improve the working cooperation mechanism.

　　"To be intensive and efficient means to break the original barriers of interest, so as to give up and stay, increase and decrease." Deputy Dai Shao ‘an, the former military attache of the Embassy in Egypt, said that what should be abandoned should be abandoned, the combination should be combined, and the adjustment should be adjusted. It is necessary to properly handle the relationship between individuals and collectives, local and overall, and units and the whole, and work together to form a new division of labor, a new structure and a new combat force generation model. (Beijing, March 11 th)

　　The Internet of Vehicles has once again taken a crucial step.

　　Recently, the "Implementation Plan for the Establishment of National Jiangsu (Wuxi) Vehicle Networking Pilot Area" was released to the public, marking the official launch of the construction of the first national vehicle networking pilot area in China. One day later, Miao Wei, Minister of Industry and Information Technology, and Wu Zhenglong, Governor of Jiangsu Provincial People’s Government jointly unveiled the first car networking pilot zone in China in Wuxi, Jiangsu. It can be said that the era of car networking has started.

　　At the vehicle networking security summit forum of the 6th National Cyber Security Publicity Week Sub-forum held recently in 2019, the vehicle networking security issue became a hot topic. Experts and scholars from the fields of vehicle networking and network security have conducted in-depth discussions on issues such as the development of vehicle networking security industry, security technology and application innovation, and actively made suggestions and suggestions.

　　Experts believe that the rapid development of the Internet industry is inseparable from the support of network security work, and the development of vehicle networking has also brought new challenges to network security. At present, the overall safety of the Internet of Vehicles is still in its infancy, which requires the joint participation of the automobile industry and the coordinated cooperation of related industries, so as to unite the strength of the industry, continue to increase R&D, innovation and investment from the aspects of technology, standards, management, even industrial system and personnel training, build a people-centered network security system of the Internet of Vehicles, and protect the security of terminal (vehicle) link data.

　　Accelerate the integration and innovation of 5G and car networking

　　In 2018, the car networking industry entered the fast lane. This year, China has successively issued a number of policy documents to promote the development of car networking.

　　In April 2018, the Ministry of Industry and Information Technology and other three departments issued the "Intelligent Networked Vehicle Road Test Management Specification (Trial)", which means that "unmanned" driving cars can be tested on more actual roads. In June 2018, the Ministry of Industry and Information Technology issued a series of documents entitled "Guidelines for the Construction of National Vehicle Networking Industry Standard System (General Requirements)", proposing that by 2020, an intelligent networked vehicle standard system that can support assisted driving and low-level automatic driving will be initially established.

　　In November 2018, the Ministry of Industry and Information Technology issued the "Regulations on the Management of Direct Communication Using 5905-5925MHz Frequency Band in Vehicle Networking (Intelligent Networked Vehicles) (Provisional)" to support the national special economic zones, new districts and free trade pilot zones to accelerate the construction of intelligent transportation systems.

　　On December 25, 2018, the Ministry of Industry and Information Technology issued the "Action Plan for the Industrial Development of the Internet of Vehicles (Intelligent Networked Vehicles)", clarifying that by 2020, a breakthrough will be made in the cross-industry integration of the Internet of Vehicles (Intelligent Networked Vehicles) industry, and intelligent networked vehicles with high-level autonomous driving functions will be applied in a specific scene scale, with the penetration rate of Internet of Vehicles users reaching over 30% and the infrastructure level of intelligent roads significantly improved.

　　Under the guidance of these policy documents, the development of China’s car networking industry has been further accelerated, and the industrial scale has been expanding.

　　On September 6, at the 2019 Expo Intelligent Transportation and Vehicle Networking Industry Development Summit Forum, the implementation plan for the establishment of the national Jiangsu (Wuxi) Vehicle Networking Pilot Area was officially released. On September 7, Miao Wei and Wu Zhenglong jointly unveiled the first car networking pilot zone in China in Wuxi, Jiangsu.

　　Miao Wei proposed to combine the commercial deployment of 5G, give full play to China’s foundation and advantages in network technology, pilot demonstration, industrial integration, institutional mechanisms, etc., and accelerate the integration and innovation of 5G and car networking; Focus on the "stuck neck" technical links such as automotive chips, computing platforms and in-vehicle operating systems, achieve breakthroughs one by one, and support qualified regions and enterprises to try first; Promote the improvement of relevant laws and regulations, speed up the construction of the vehicle networking pilot area, strengthen the exploration of management mechanism and operation mode, improve the level of safety protection technology, and ensure the healthy development of the vehicle networking industry.

　　Some experts believe that the development of the car networking industry is conducive to improving the level of car networking and intelligence, realizing automatic driving, developing intelligent transportation, and promoting information consumption. It is of great significance for China to promote supply-side structural reform, promote the construction of a manufacturing power and a network power, and achieve high-quality development.

　　Give play to the key role of network security

　　The development of car networking is a profound change involving the value chain, industrial chain and innovation chain. During the 13th Five-Year Plan period, China will take scientific and technological innovation as the guide and intelligent networking as the main direction, and strive to create new formats and new kinetic energy, and promote the transformation, efficiency and upgrading of the automobile industry, so as to achieve the goal from big to strong.

　　Zhao Zhiguo, director of the Network Security Administration of the Ministry of Industry and Information Technology, believes that "the Internet of Vehicles is a new thing, with a new industrial form, a large industry span and a wide range of applications. Its perfection and development require vehicle companies, parts research and development companies, Internet companies, universities, and scientific research institutions to jointly explore and work together."

　　"Without network security, everything is impossible." According to Shen Changxiang, an academician of China Academy of Engineering, safety is the premise of development, and development is the guarantee of safety. Network security threats and protection are eternal themes, and cyberspace is much more fragile than imagined. The traditional "blocking and killing" has been difficult to deal with attacks, so it is necessary to establish a computing framework of active immunity. By building a triple protection framework of active immunity supported by a trusted security management center, the active immune computing model with measurable and controllable calculation results and coexistence of protection and calculation can be achieved. Shen Changxiang said frankly, "The Internet of Vehicles is a typical Internet of Things. It is necessary to simplify complex problems with the hierarchical protection safety management center architecture and form a safety management center according to the hierarchical protection requirements."

　　With the advent of the 5G era, is the Internet of Vehicles a joy or a worry? Wang Yongjian, a researcher at the Internet Emergency Center, said that the Internet of Vehicles in the 5G environment faces five major security threats: intelligent networked vehicles, mobile intelligent terminals, Internet of Vehicles service platforms, wireless communication in the Internet of Vehicles, data security and privacy protection in the Internet of Vehicles. The security risks introduced by 5G generalized access in wireless communication mainly include: traffic attack, identity forgery and malicious interference.

　　To this end, Wang Yongjian suggested that in terms of technical monitoring means, it is necessary to study the intelligent abnormal traffic monitoring mechanism based on deep learning and other technologies, improve the network security protection capability of the Internet of Vehicles, and provide monitoring and early warning functions and network control functions; Based on the 5G authentication framework and communication encryption algorithm, a trusted "man-vehicle-road-cloud" collaborative communication is built to realize timely identification and alarm of unauthorized access. At the same time, the monitoring and positioning technology of abnormal strong interference is studied, and the monitoring system is intelligently arranged based on roadside facilities to monitor important frequency bands in real time, so as to realize the cooperative positioning of abnormal interference sources in satellite navigation and other systems.

　　Build a network trust support platform together.

　　How to deal with the security risks faced by the Internet of Vehicles? Experts attending the meeting put forward suggestions from many angles.

　　"The car network security trust system is an important means to solve the network security problem of the car network." Zheng Jihu, director of the data resource center of China Automotive Technology and Research Center Co., Ltd., said that in order to solve the problems faced by the automobile industry in the process of establishing a network trust system, China Automobile Center has jointly established a network trust support platform for the automobile networking with relevant enterprises, universities and research institutes to provide network security for the intelligent and networked development of the automobile industry.

　　It is worth noting that "China Internet of Vehicles (Intelligent Networked Cars) Network Trust Alliance" was launched at the forum. According to Zheng Jihu, the alliance aims to build a better trust support platform for the Internet of Vehicles (IoT), and to connect the upstream and downstream industrial chains of the IoT trust system.

　　Yang Bin, senior vice president of Tianrongxin Company, pointed out that "to do a good job in the security protection of the Internet of Vehicles, we need to learn from the protection technology of IT network security, combine the business scenarios of the Internet of Vehicles, and adopt a variety of protection technologies to work together."

　　"For example, through authentication and encryption technology, the trusted identity authentication and communication encryption transmission of the in-vehicle network, the car and the cloud, the car and the mobile phone can be realized, and attacks such as command cracking, replay attacks, identity forgery and data theft can be prevented." Yang Bin said, through the vehicle intrusion detection technology based on white list, combined with security incident reporting and cloud strategy distribution, the attack detection such as abnormal traffic and abnormal message identification in the vehicle can be realized.

　　For another example, the in-vehicle security domain is isolated through the in-vehicle security gateway, so as to realize access control between key interconnected components in the vehicle, depth detection of CAN messages, security audit, intrusion prevention, etc., and realize the security protection of the in-vehicle network boundary.
