The movie "Fighting Evil" will be premiered in Iqiyi and Tencent soon. On February 6th, the movie was held in Beijing. Director Huo Suiqiang, chief producer Yan Dong, producer Deng Xiao, starring Xie Miao and Andy On, starring Hong Shuang, Gu Jing, Li Zijia and other creative artists attended the movie-watching activities in Beijing, and started a hearty and high-burning movie-watching tour with the media guests and audience at the scene. In the post-screening interaction, Xie Miao and Andy On talked about the feeling of cooperation for the first time and restored the scene of playing the title of the play, and they created and shared the original intention and behind-the-scenes story of the action movie. Fans responded enthusiastically at the scene, sending Spring Festival couplets, playing with hot stalks and fancy confession, and lighting the first fire of action movies in spring together.

　　Xie Miao VS Andy On Shuangxiong’s first cooperation leads to expectations.

　　The most eye-catching topic in the movie "Fighting Evil" is bound to be the first cooperation between Xie Miao and Andy On. Xie Miao expressed his initial appeal for "Anti-Evil", one of which was "the purest action movie" and the other was "it is very important to have a good opponent". When he learned that he was cooperating with Andy On, he said "there is nothing to say". Andy On also responded, "In fact, I watched Xie Miao’s play when I was a child." The two not only chatted about their feelings of cooperating with each other for the first time, but also copied the wonderful confrontation in the film one by one, which made people clap their hands. The combination of the two powers, director Huo Suiqiang believes that "they are here, everything can be done."

　　For the limited cooperation between the two, the fans sent their blessings without hesitation. Some viewers shouted excitedly, "You are the most annoying group", and some male viewers showed their love for Andy On on the spot, hilariously calling him "the only man who can make me not watch beautiful women while watching movies", and fans even directly sent earthy love words to express their love. Andy On and Xie Miao gave sincere feedback. Not only did they send New Year’s red envelopes on the spot, but Andy On guessed the meaning of Xie Miao’s Beijing dialect and interacted with each other, which filled up the atmosphere of the Spring Festival movie. It was simply a big fan dream scene.

　　The activity also specially arranged the link of "Repelling Villains, Fighting Evil to Keep Peace", with Xie Miao and Andy On boxing and kicking, giving the audience the hardest New Year wishes. "Watch" Fighting Evil "and keep safe" has become the most straightforward and direct confession of this action film, and the New Year benefits that the two men have limited fit are really unusual.

　　Limit 8 fights with violence to attract on-site praise.

　　In the discussion related to the movie "Fighting Evil", "limiting eight fights" became a high-frequency word, among which "icehouse duel" was Xie Miao’s most impressive fight, and he thought that "the weapon design of chain and hammer was also novel", which revealed in detail their experience of cultivating tacit understanding at the scene. "A mirror-to-the-bottom fight in the sewer" is unforgettable for both of them. Andy On bluntly said that "his arm was sore for many days".

　　After the screening, the audience gave feedback that not only the action style of the film was highly integrated, but also the props, guns and even fighting weapons appeared in the scene were highly adapted to the characters, plots and scenes, which improved the viewing experience and made the film full of coolness. Fans said that "this is the coolest and most burning drama I have seen recently, and I am sweating directly, especially worried that the actors will be injured." In addition, the other three leading actors, Hong Shuang, Gu Jing and Li Zijia, who came to the scene, were also recognized and praised by the audience for their wonderful performances in the film.

　　At the scene of the movie "Evil", director Huo Suiqiang shared the creative process and initial heart of the film from the beginning of shooting. He said that the film wanted to call for the simple values of justice, and bluntly said, "I want to show our country’s resolute anti-drug attitude with the most hardcore action movies."

　　The film "Fighting Evil" was produced by Beijing Aiqiyi Technology Co., Ltd., Ningbo Yunshui Fangzhi Culture Media Co., Ltd., Shanghai Tencent Penguin Film and Television Culture Communication Co., Ltd. and Chongqing Dongyu Culture Media Co., Ltd., and jointly produced by Menghe Qiyuan (Beijing) Culture Media Co., Ltd., Hangzhou Recommended Culture Co., Ltd., Dongheng Film (Hangzhou) Co., Ltd., Beijing Lianrui Film Co., Ltd., Shoulian Kunrui Culture Media Co., Ltd. and Beijing Shifang Xihe Culture Development Co.,

Residents deliver old newspapers in the "Little Yellow Dog Intelligent Garbage Sorting and Recycling Machine".

Text/Photo Peninsula reporter Wang Liping correspondent Xu Lingling

On January 2nd, in Tongde Road Community Square, Hefei Road Street, a dozen residents watched in front of a yellow and blue iron cabinet similar to a locker. The first resident was fiddling with the electronic screen in the center of the cabinet. After clicking "End Delivery" on the screen, a two-dimensional code marked with 44 cents appeared on the screen. It turned out that it was an intelligent garbage sorting and recycling machine. It took less than half a minute to put the waste materials into it, and the money exchanged could be returned. According to the relevant staff, this is the first real-time cash-back intelligent garbage sorting and recycling machine in Shibei District. At present, there are 220 sets in the city. Next, Shibei will be laid out in Jimo Road, Yan ‘an Road and Ningxia Road, and 350 sets will be put in the city before the Spring Festival.

It takes less than half a minute to refund the money on the spot.

"It’s so convenient. I just put in a pound of newspaper. After operating for less than half a minute, my mobile phone received 44 cents. Now the waste recycling is so foreign." Liu Jianchun, a citizen who came to deliver the old newspaper, said that when this "little yellow dog" was first installed in the community square, it was attracted by its beautiful appearance, and every day he looked forward to the early installation.

Liu Jianchun’s "Little Yellow Dog Intelligent Garbage Sorting and Recycling Machine" is an iron cabinet about 5 meters long and 2 meters high behind her, which is divided into six cabinets. Each cabinet is marked with the types of recycled items, including paper, textiles, metal, plastic, glass and harmful waste. Each cabinet has an input port. On the lattice cabinet in the middle of the box, there is a console with an electronic screen installed on it. Residents.

According to the staff’s demonstration, the reporter found that first of all, waste paper, textiles, metals, plastic bottles and other garbage should be put into different boxes according to the logo. Then, the recycling machine will intelligently identify or weigh the input garbage, and finally calculate the cash back amount according to the market price of different waste products. The benefits obtained from each launch can be queried from the APP or WeChat applet in real time. When the amount reaches 10 yuan, it can be withdrawn through the bank card or WeChat red envelope tied to the APP account.

Liu Jianchun said that there are many clothes she doesn’t wear, used newspapers and various cans at home, and she doesn’t know what to do with them. "Now with this little yellow dog, these wastes finally have a place to go. Putting them into the little yellow dog and changing money is really killing two birds with one stone." Liu Jianchun said that now more and more residents around her have tasted the sweetness of garbage sorting, and they all volunteered to be propagandists of garbage sorting. Everyone said that those who have abandoned garbage can try the "little yellow dog" in our square, which is especially good!

The recovery price fluctuates in real time according to the market.

The reporter saw on the display screen of this recycling equipment that the garbage recycling of "Little Yellow Dog" is classified and priced, including 0.2 yuan/kg for textiles, 0.7 yuan/kg for plastics, 0.7 yuan/kg for paper, 0.6 yuan/kg for metals and 0.04 yuan/bottle. "Our recycling price is based on real-time pricing of industry price fluctuations." Wang Long, head of Qingdao Branch of Xiaohuanggou Environmental Protection Technology Co., Ltd., said that compared with the recycling price in the market, some items will be lower than the market price, some will be flat, and some will even be higher than the market price. "Because this is a large category of prices, such as paper, the paper waste station collects a variety of prices, such as a price for newspapers, a price for yellow cardboard, and a price for books. These prices are higher than ours, but the paper cover is lower than ours." Wang lung said.

It is understood that as the first intelligent garbage sorting and recycling machine supporting real-time cashback in Shibei District, residents can put waste plastics, textiles, metals, paper shells, glass and other wastes that are not used at home by inputting their mobile phone numbers or WeChat scanning codes. The recycling machine will intelligently identify and weigh the put-in garbage, and finally calculate the cashback amount according to the market prices of different wastes, thus realizing intelligent operation integrating intelligent operation, intelligent weighing, real-time cashback and WeChat cash withdrawal. Xiaohuanggou Company is equipped with specialists who are responsible for explaining how to use it to residents, and a special technical department is responsible for treating and emptying saturated garbage. Since the recycling machine was put on the square on December 16, 2018, it has attracted nearly 400 residents to scan the code for registration in more than 10 days, and it handles garbage 5-6 times and nearly 50 kilograms every day.

"While promoting waste sorting, it has also raised residents’ awareness of environmental protection." The relevant person in charge of Hefei Road Street said that "Little Yellow Dog" can help residents to master the method of garbage sorting more conveniently and quickly, and cash can be directly sent to APP to realize WeChat cash withdrawal, which can effectively stimulate the initiative and consciousness of residents to participate in garbage sorting and make the concept of garbage sorting more deeply rooted in people’s hearts.

Residents drove in waste materials.

"In October 2018, we invested in the first’ Little Yellow Dog Intelligent Garbage Sorting and Recycling Machine’ in Qingdao, and then successively launched it in Chengyang and Jimo. At present, there are 220′ Little Yellow Dogs’ in the city." Wang Long said that as far as the current situation is concerned, paper and textile products are the main waste products put by the public. In a community of about 400 households, the weight of waste recycling in one week is about 1,000 kilograms.

Wang Long said that some people are now driving cars and carrying big bags of waste materials, and the recognition of residents is getting higher and higher. They are also actively guiding residents to carry out normal classification. "This requires a process. After all, garbage classification needs to improve the quality of the whole people." Wang lung said.

According to Wang Long, unlike the traditional intelligent garbage sorting, "Little Yellow Dog" is the only garbage sorting and recycling machine in China that can realize real-time cashback. It mainly sorts household garbage through the source. "There is our professional cleaning iron army at the middle end and a sorting center at the back end, forming a closed loop and sorting the whole domestic garbage." Wang Long said that this model has realized the intelligence of front-end garbage sorting, including direct input, weighing and intelligent cashback, and residents can conveniently cash back in real time through garbage sorting, which is a more affordable way for residents to participate in garbage sorting. "At the back end, we are building a sorting center in Chengyang District, Qingdao, and now it is in the process of construction. Later, we will invest in professional garbage sorting equipment to form a unified sorting at the end, and reprocessing and reproduction will form such a cycle." Wang lung said.

"This is the first equipment we put into Shibei District, which also marks our official entry into Shibei District. Next, before the Spring Festival, we will complete comprehensive coverage of Yan’ an Road Street, Jimo Road Street and Ningxia Road Street, all communities." Wang Long said that before the Spring Festival, it is estimated that more than 350 sets of equipment will be laid in Qingdao to provide better services and clean environment for more residents and more communities.

"Made in China 2025" puts forward "energy-saving and new-energy vehicles" as a key development field, and makes it clear that "we will continue to support the development of electric vehicles and fuel cell vehicles, master the core technologies of low-carbon, informationization and intelligence of automobiles, enhance the engineering and industrialization capabilities of core technologies such as power batteries, drive motors, efficient internal combustion engines, advanced transmissions, lightweight materials and intelligent control, form a complete industrial system and innovation system from key components to complete vehicles, and promote energy conservation and innovation of independent brands. The development strategy has pointed out the direction for the development of energy-saving and new energy automobile industry in China.

First, the automobile industry is an inevitable choice for the strategy of manufacturing a strong country.

From the perspective of manufacturing power, the automobile industry is listed as a national strategic competitive industry because of its important position in the national economy and its important contribution to economic growth. The second industrial revolution, represented by automobiles, lasted for more than a hundred years, and manufacturing powers such as Europe, America and Japan were all automobile powers. At present, with the third industrial revolution as the background, global technological innovation and economic recovery are increasingly active, and the automobile industry is the most comprehensive and large-scale carrier and platform for technological innovation such as digitalization, networking, intelligence, new energy, new materials and new equipment involved in the third industrial revolution, so it has once again become a representative industry of industrial revolution and industrialization level.

Whether it is driven by innovation or the sustainable and healthy development of the national economy, the automobile industry with large-scale effect and industrial correlation should be a strategic industry. The added value of China’s automobile industry accounts for only 1.53% of GDP, which is far from the 4% level of a powerful automobile country. The reason is that we are at the low end of the industrial chain, manufacturing rather than creating, so a stronger automobile industry will play a more important role in the development of the national economy. At the same time, the strong industrial correlation and driving force of the automobile industry is also a concentrated expression of the technological innovation level of China’s manufacturing industry.

Second, the main problems and constraints faced by the development of the automobile industry

(1) Lack of understanding of the important strategic position of the automobile industry in the construction of manufacturing power and economic transformation and upgrading, and lack of clear, systematic and sustainable industrial development strategy and top-level design. In recent years, China’s automobile industry has developed rapidly, but the development strategy of automobile industry is still unclear and lacks a systematic and complete strategy of automobile power. The unsustainability of the automobile industry policy leads to large fluctuations in the domestic automobile market, and the production capacity of enterprises is either difficult to adapt or idle, which intensifies the low-level competition in the domestic market and makes the industry big but not strong.

(2) The key core technologies are controlled by people, and the ability of independent innovation is weak. At present, China’s major automobile groups have not fully mastered key technologies in the fields of passenger car platform technology, engine system and new energy batteries, and have not yet formed a complete industrial system and capability.

(C) the lack of basic research common technology platform and innovation system support. At present, China has initially established an innovation system combining government and Industry-University-Research. However, due to many factors such as industrial organization structure, enterprise scale and governance model, the research on basic common technologies is still weak. In addition, there is no cross-industry, cross-field and cross-technology coordination management mechanism.

(D) The overall technical level and R&D capability of the traditional automobile industry are weak, and the supply chain system is incomplete, which restricts the rapid development of strategic emerging industries. Due to the relatively weak innovation ability and R&D investment intensity of traditional automobiles and related industries in China, the related industrial chain is not perfect, and some key parts and raw materials and key components depend on foreign countries, which restricts the rapid development of energy-saving and new energy vehicles.

(5) The development of soft environment such as business operation mode and humanities is lagging behind, and it still takes time to cultivate independent brands. At present, the business model dominated by the automobile industry is still uncertain, and the construction of automobile cultural environment lags behind. At the same time, the technical level, product quality and performance of domestic automobiles still lag behind the international advanced level and lack core competitiveness.

Third, energy-saving and new energy vehicles are the only way for automobile manufacturing to become a strong country.

With the rapid growth of global car ownership, the pressure of energy, environment and safety is increasing. From the perspective of sustainable development, the automobile industry must solve the four public hazards of energy, pollution, safety and congestion recognized by the world. Low-carbon, information-based and intelligent vehicles have been considered as the ultimate solution.

Countries such as the United States, Japan and Europe have put forward the development goals of low carbon, electrification and intelligence of automobiles, and accelerated the transformation and transformation of the automobile industry under the background of the development of new generation information technology and clean energy technology by strengthening technological innovation and cross-industry synergy and integration.

In terms of low carbon, major automobile developed countries have basically put forward the goal that the fuel consumption of passenger cars will reach 5L/100km in 2020 and 4L/100km in 2025.

In terms of electrification, with the active promotion of governments and the efforts of major automobile manufacturers, based on the technical progress and cost reduction of power batteries, the process of global automobile electrification is accelerating. In 2014, the global sales of electric vehicles reached 300,000. According to the prediction of the International Energy Agency, by 2030, electric vehicles will account for 30% of the world’s automobile sales.

In the aspect of intelligence, advanced countries in the world have defined the blueprint of automobile industry as a digital model to realize the integration of design, manufacturing and service based on network. For example, German Industry 4.0 clearly defines the information and physical integration system of smart cars, facilities and manufacturing services based on the Internet, and defines the timetable for promoting the information and physical integration from automobile mechatronics to intelligent driving. In 2050, the European Union plans to form a traffic area with integrated intelligence and interconnected cars, and the connected cars will be listed in 2015.

In 2014, the sales volume of automobiles in China reached 24.39 million, and by the end of 2014, the number of automobiles was 145 million. In recent years, China’s dependence on oil imports is close to 60%, and oil consumption in the transportation sector accounts for nearly 50%, of which nearly 80% is consumed by automobiles. At the same time, the contradiction between urban road traffic has become increasingly prominent, and automobiles have become an important source of environmental pollution. Thus, the automobile industry shoulders the important responsibilities of improving traffic, protecting the environment and saving energy. It is urgent for China automobile industry to develop energy-saving and new-energy vehicles and realize low-carbon, electric and intelligent development. According to the current situation of China’s automobile industry, based on the existing foundation of the automobile industry, promoted by the national strategic emerging industries and energy conservation and emission reduction regulations, it is possible to form a low-carbon, information-based, intelligent energy-saving and new energy-saving automobile advantage field during the "Thirteenth Five-Year Plan" period.

For motorcycle enthusiasts, understanding the displacement of motorcycles is a very important indicator. Common motorcycles have displacement of 100, 112,150 and 175, while motorcycles with displacement above 200 are relatively few. If you have any other questions, you can continue to ask me questions.

The displacement of a motorcycle is usually expressed by CC, and 1 CC is equal to 1 milliliter (1ml), that is, 1 cubic centimeter (1cm), which is the volume of the engine. Therefore, the displacement of motorcycle refers to the volume of engine piston from bottom dead center to top dead center. If you want to know how many CC motorcycles have, you can refer to the following.

The largest motorcycle displacement in the world is 5730cc, while the smallest is 25cc. After understanding the concept of displacement, let’s take a look at the displacement of Maserati motorcycles. Maserati m157c22979cc has a displacement of 2,297.9cc, while Maserati President has a displacement of 2180-2780cc, Maserati GT has a displacement of 2180-2680cc, and Maserati GranCabrio has a displacement of 2600-2780cc.

Indian officials admitted that the computer network of the largest Kudankulam nuclear power plant was attacked from outside in October. The nuclear power plant is mainly designed and supplied by Russia with reactor units to provide electricity for the southern power grid of India. This nuclear power plant has become one of the largest cooperation projects between India and Russia.

According to the American Bulletin of Atomic Scientists, although the reactor operation of Kudankulam nuclear power plant has not been affected, this incident once again warns that the two biggest security risks of human society, namely cyber attacks and nuclear deterrence, are in a dangerous "collision", and its serious consequences may completely turn into uncontrollable man-made disasters.

Kudankulam nuclear power plant　

There have been more than 20 cyber attacks on nuclear facilities in the past 30 years.

The cyber attack on India’s nuclear power plant naturally reminds people of the past when Iran’s nuclear power plant was attacked by the "Shenzhen" virus in 2010, resulting in the paralysis of more than 1,000 centrifuges. In fact, the incidents of cyber attacks on nuclear power plants continue.

According to media reports, there have been more than 20 known cyber attacks against nuclear facilities since 1990. These incidents include malicious intrusions caused by software vulnerabilities and test updates. Although compared with the "Shenzhen" virus incident, these are not well known, but it also clearly shows that nuclear facilities can no longer be spared from cyber attacks. Cyber attacks on nuclear power plants may lead to great disasters and should be highly valued.

For all this, the initiator of cyber warfare and nuclear weapons, the clearer the result, the more fearful the psychology. The United States has regarded cyber attacks as the primary threat beyond terrorism. As early as 2009, after Obama, the "cyber president", took office, he immediately launched a 60-day cyberspace security assessment, and immediately took cyber security, nuclear security and combating terrorism as a "trinity" national strategy. Former US National Intelligence Director and Admiral Mike McConnell once pointed out that "terrorist organizations will master complex network technologies sooner or later, just like nuclear proliferation, but it is easier for them to achieve."

Informatization is a "double-edged sword", which is a golden opportunity and contains unprecedented risks. As the digitalization of nuclear reactor instruments and control systems increases, the possibility of harm caused by malicious and unexpected network attacks is also increasing. At the same time, according to a report published by Chatham House, a British think tank, in 2015, network security is a common shortcoming in the nuclear power industry, which runs through management, training and user behavior. Both natural loopholes and man-made defects may become convenient doors for cyber attacks and directly ignite the fuse of nuclear facilities out of control.

The consequences may be as the then US Secretary of Defense Panetta warned on October 11, 2012, "Cyber attacks can destroy the operation of passenger trains, pollute water supply or shut down most of the electricity supply in the United States, which can be the online version of Pearl Harbor incident, causing a lot of physical damage and casualties, paralyzing daily operations, shocking people and creating new fears."

The accident at Chernobyl nuclear power plant left a deep impression on the world.　　

Indian nuclear power plant or infected with Trojan virus

The malware infected in the intranet of India’s nuclear power plant is said to have been developed by a hacker organization in a certain country and belongs to the variant of backdoor Trojan horse. Its functions include stealing keyboard records of devices, retrieving browser history records, and listing running processes, etc. It does not seem to be a malicious direct destructive virus. But not coincidentally, just a few days before the media reported the cyber attack, the nuclear power plant unexpectedly shut down a reactor. Although the relevant institutions strongly deny that the incident is related to the invasion of malicious software, the consequences of the network attack on the power grid are likely to be unpredictable and more difficult to control.

The thrilling collapse of Ukrainian power grid in the cold winter of 2015 was considered by Russian hackers. In March this year, Venezuela’s national power grid was paralyzed in a large area, and its president and information minister called it a cyber war carefully planned by the United States. In June this year, the suspense of multi-country power grid paralysis in South America, Russian experts must be American cyber warfare exercises, in an attempt to trigger social unrest in the region. In fact, including the rumors of American officials that their cyber forces preset malicious code in the Russian power grid, there is a shadow of "undeclared war" behind them, which represents a new invasion mode that can quietly cause large-scale damage; Even more, the fear of "cutting the bottom of the pot" is enough to destroy the electric energy that modern society depends on and cause the paralysis of the whole society.

Besides, the terrorists haven’t stopped thinking for a moment. The demonstration effect of the network power makes the terrorists’ hearts beat faster, and it is very likely that they will finally master the advanced cyber attack technology. The world has long been alert to this. On December 17, 2013, the United Nations Security Council unanimously adopted Resolution 2129, explicitly cracking down on the use of the Internet to commit terrorist acts. However, at present, cyber terrorism is only in the initial stage of development, that is, using the network for mobilization, publicity, series connection, fund-raising and other activities. Once terrorists master the leading technology of cyber attacks, it is entirely possible to cause heavy casualties. This is the "cyber 911" or "cyber Pearl Harbor" incident that senior American officials have been warning about.

In recent years, the US military and intelligence departments have vigorously developed cyber attack weapons, which has increased the risk of the proliferation of cyber weapons.

Be wary of the integration of cyber attacks with nuclear disasters and terrorism.

The United States regards cyber security, nuclear deterrence and counter-terrorism as a "trinity" national strategy, but the result is not satisfactory, but there are bad signs of the convergence of the three major risks. Although there are many reasons for this, the "law of the jungle", double standards and hegemonic thinking that it has been pursuing are hard to escape. From the "Shenzhen" virus to the release of the "eternal blue" weapon, it undoubtedly gives terrorists technical guidance and demonstration effect, and combating cyber terrorism has become a common difficulty for human society. To find a solution, we should not only devote ourselves to the difficult process of destroying nuclear weapons, but also strictly control the uncontrolled implementation of cyber attacks and prevent the creation of a breeding ground for terrorism.

Regarding the lessons that should be learned from the cyber attack on India’s nuclear power plant, the focus is on safety culture. The Hague Communiqué in 2014 also listed nuclear safety culture as the first of the three pillars of nuclear safety. The Nuclear Regulatory Commission (NRC) of the United States has put forward guidelines to its operators for human resources development and performance evaluation to improve the network security of nuclear power plants. The National Nuclear Military Administration (NNSA) of the United States has incorporated network security into its security assessment, technical exchange and training plan. The United States has also cooperated with the International Atomic Energy Agency (IAEA) to develop a network security training course for nuclear power plant operators; The International Atomic Energy Agency has also published a technical guide on computer security, and has also held a network security course for nuclear power plant operators for the first time. Organizations such as the World Nuclear Safety Association and the World Association of Nuclear Operators can also share information on best practices.

Despite such efforts, it is not enough. Although the lack of safety culture needs to be solved urgently, the harm of jungle culture is even greater, which is the real catalyst for the integration of cyber attacks, nuclear disasters and terrorism. The nuclear explosion in Hiroshima and Nagasaki in 1945 should not be forgotten. In 1986, the Chernobyl nuclear power plant exploded, and the radiation pollution was 100 times that of the atomic bomb explosion in Hiroshima, Japan. The Fukushima incident in 2011 shocked the whole world, and more than 200,000 people were directly implicated. Eight years later, the impact has not been completely eliminated.

To this end, in the face of cyber attacks on India’s nuclear facilities and concerns about cyber terrorism, we need to warn again: First, cyberspace is interconnected, and no one can be immune to it. The shortcomings of others may be the springboard to attack you; Second, cyber attacks on nuclear facilities are fundamentally different from those in Hiroshima and Nagasaki, and it is impossible to enjoy the fruits of nuclear deterrence without suffering from nuclear explosions after dropping nuclear bombs; Third, human society must abandon the "jungle law" and firmly establish a new culture of "cyberspace destiny community" in order to make cyberspace a common well-being.

　　On the morning of November 29th, shortly before the opening ceremony of the grand celebration of the 130th anniversary of Wuhan University, a simple donation signing ceremony was quietly held in a small conference room in the administrative building of the university.

　　Lei Jun, an alumnus of the Computer Department of Wuhan University in 1987 and founder, chairman and CEO of Xiaomi Group, donated 1.3 billion yuan to his alma mater. This donation has set a new record for the largest single donation since the establishment of Wuhan University, and it is also the largest personal cash donation received by alumni in universities across the country. This triggered a hot discussion about "other people’s alumni" on the Internet.

　　As an outstanding alumnus of Wuhan University, Lei Jun’s story of studying and starting a business has always been talked about by Wuhan University students. During his study at Wu Da University, Lei Jun completed all the credits required for four years in the university in just two years. Shortly after graduation, he joined Beijing Jinshan Software Co., Ltd. and led the company to grow and develop. In April 2010, Lei Jun founded Xiaomi Company, and now Xiaomi is the top three smartphone manufacturers in the world.

　　Lei Jun has said more than once that Luojiashan is the place where dreams are started, and the professional knowledge and learning ability he learned at Wuhan University have laid a good foundation for his later entrepreneurship. In order to be grateful and give back to his alma mater, in 1997, just six years after graduation, Lei Jun began to donate to his alma mater and set up a "Tengfei Scholarship" at Wuhan University.

　　Since then, Lei Jun has donated a number of donation projects to his alma mater, including the establishment of the "Lei Jun Scholarship" and "Lei Jun Science and Technology Building" of Wuhan University, with a total amount of 130 million yuan. On October 20, 2016, Lei Jun donated money to support Wuhan University to build an artificial intelligence teaching and research building.

　　At the 9th Alumni Forum of Wuhan University that afternoon, Lei Jun told his schoolmates the behind-the-scenes story of donating 1.3 billion yuan to his alma mater.

　　"I have always had an unforgettable love for my alma mater. The small achievements I made today are inseparable from the cultivation of my alma mater." Lei Jun said that it was Wu Da who shaped him, let him find his dream, learned the method of learning, and gave him the most precious wealth in his life.

　　Lei Jun is especially grateful to his alma mater for his tolerance. He has always encouraged students to explore and innovate in technology. Coupled with the free and relaxed environment and laboratory conditions, he has the courage to set no limits.

　　Lei Jun comes from an ordinary family in Xiantao, Hubei. More than 30 years ago, when he was studying at Wuhan University, he studied hard and supported himself by scholarships. He once won the highest scholarship set up by an entrepreneur at school — — 2000 yuan, which is equivalent to the salary of ordinary people for several years at that time. He silently vowed in his heart that "it will be returned ten times, one hundred times and ten thousand times in the future."

　　Lei Jun also had a wish. Because at that time, the best teaching building in Wuhan University — — I feel very happy in class in Shaw Building, so he made a wish to donate a building to Wu Da. Now, these two wishes have come true.

　　Lei Jun said that in the eyes of him and many alumni, Wu Da is the best university in the world. In order to make Wu Da better and better, everyone can give back to his alma mater with practical actions. In particular, he said that he never advocated comparing donations. Many alumni actively donated money to celebrate the 130th anniversary of Wu Da University. Every donation is the love of alumni for their alma mater, and the weight is the same.

　　According to reports, Lei Jun’s donation mainly focuses on three directions: supporting the basic research of six disciplines of mathematics, physics, literature, history and philosophy, supporting scientific and technological innovation in the computer field, and supporting the cultivation of college students.

　　【Pacific auto network tire channel】 This issue of Xiaobian will introduce you to sports tires. The biggest feature of sports tires is high performance and excellent handling performance. There are many sports tires on the market, and the more choices car owners face when changing tires, the more tangled they tend to be. The average car owner will buy according to several aspects: brand, price, original tires and friends’ introduction, etc. These are good methods, but the most important thing is that the car mainly knows the tires and knows what kind of tires to choose. Therefore, Xiaobian will introduce the mainstream representative sports tires on the market, so that everyone can understand them first and then make a choice.　　

　 　In order to facilitate your reading, please first understand the following parameters:

　　Hub diameterAlso called rim diameter, it refers to the size of the tire suitable for mounting on the hub.load index, refers to the maximum upper limit load of the tire.speed, refers to the maximum upper limit speed of the tire.figure, refers to the structure of tread grain, mainly including symmetry, asymmetry and single direction.abrasionindex, is the main measure of tire tread wear performance and service life of the logo, the higher the score, the more wear-resistant.Traction index, which is a measure of the adhesion between tires and the ground, is divided into four levels: AA, A, B and C, with AA being the highest.Heat generation index, is the ability of tire to resist heat generation, which is related to the high-speed performance of tire. It is divided into three levels: A, B and C, with A being the best. (Please click for more details.This > > >)

　　　 What is a sports tire? Sports Performance The tread groove of the tire is relatively wide and the tread blocks are relatively large, in order to have good drainage performance and strong grip on the ground, but this kind of tire has obvious shortcomings, such as loud noise and poor comfort. Sports tires and comfortable tires are two extremes. To pursue the sports performance of tires, we must give up the comfort performance, and vice versa. However, there are also some tires that can achieve comfortable and well-balanced movement, such as Pirelli’s P Zero Rosso and Goodyear Sanneng.
