[car home Information] A few days ago, Dong Yuhui of New Oriental "unexpectedly" became popular, and he himself summed up the popularity as: "Luck will always favor those who are always ready." He thanked himself for reading a lot of books in college to reserve enough knowledge, which he could share in the live broadcast and gain everyone’s recognition. BYD seems to be highly consistent with Dong Yuhui’s popularity. The change from "ugly duckling" to "golden phoenix" is really a textbook-style existence in the automobile circle. BYD’s success is not entirely due to luck, but behind it is BYD people’s far-sighted strategic vision and hard work.

● Looking back in 2023

　　In 2021, BYD’s annual sales volume was only 730,000 units, while in 2022 and 2023, BYD’s sales volume increased by leaps and bounds, reaching 1.86 million units and 3.02 million units respectively. What is the concept of 3.02 million units? According to the data of the Association, in 2023, the wholesale sales volume of new energy passenger cars in China was 8.88 million units, which means that BYD’s new energy vehicle sales accounted for 34% of the national new energy vehicle sales, more than 1/3. If fuel vehicles are included, BYD’s sales account for 14% of the entire passenger car market, which is about 1/7, according to the annual passenger car sales of 21.62 million units estimated by the Federation.

　　How fast has BYD made progress? Comparing the "Juan Wang" car companies horizontally, FAW-Volkswagen has always been one of the best car companies in China, and the sales volume of FAW-Volkswagen was basically the same from 2021 to 2023. Tesla has flourished in the field of new energy vehicles in recent three years, and its fist product Model Y has been the first in passenger car sales in the past six months, and Tesla’s progress is also quite obvious. But let’s compare BYD’s progress speed, which is simply a leap-forward change.

　　Among the top ten models sold in the past six months, BYD has five seats, namely Qin PLUS, Song PLUS, Seagull, Yuan PLUS and Dolphin. From the product price point of view, BYD’s products with a price of less than 300,000 yuan are more popular, including Han and Tang whose price exceeds 200,000 yuan.

"Top five automobile sales in the past six months"

　　As we said at the beginning, BYD’s popularity is not just luck. Behind BYD’s success today is BYD’s bet on new energy in the past 20 years. When BYD exhibited its first electric car ET at the Beijing Auto Show in 2004, it was ridiculed and laughed at by many people. Today, 20 years later, if any car company does not have a new energy vehicle, it may really be laughed at.

『In 2004BYD exhibited the first electric car ET at Beijing Auto Show.

　　In addition, the word technology has been engraved in BYD’s bones, which makes BYD go faster in 2023. In 2023, BYD successively introduced new technologies such as Yunqi, Yifangfang (which can turn around in the same place), DMO super hybrid off-road platform, emergency floating ability, etc., which also made BYD have a new breakthrough in high-end brand layout in 2023. Looking forward to U8 and equation Leopard Leopard 5, it will be introduced to the market this year.

"BYD Cloud"

　　The launch of high-end models stems from the technical strength behind them. Wang Chuanfu once said, "High-end brands should rely on design and technology instead of stacking configuration. This is an opportunity for China brands." Li Yunfei, general manager of BYD’s brand and public relations department, once revealed that "BYD’s R&D expenses are much higher than its net profit. For example, from January to September this year, BYD’s R&D investment was more than 29 billion yuan, while its profit was only more than 21 billion yuan. At present, BYD has 11 research institutes, more than 90,000 technicians and more than 40,000 patents. In 2023, BYD recruited 30,000 fresh graduates as engineers, 60% of whom were masters and doctors, and 700-800 people came from famous schools such as Tsinghua and Peking University. "

　　In the market above 300,000 yuan, BYD only has Tengshi D9 sales performance. Wang Chuanfu, chairman of BYD, said in the first quarter of 2023 that "the high-end brand market is facing reshuffle, and it is estimated that Tengshi will sell 20,000 units by the end of 2023." There is still a gap at present. Wang Chuanfu also said, "BYD started with a sales target of 3 million vehicles this year and tried to double it to 3.6 million vehicles." Although BYD has achieved its sales target, it is slightly different from the best expectation. It can be seen that Wang Chuanfu is optimistic about the new energy market, especially the high-end market, but BYD still needs time to cultivate its impact on the high-end market. However, looking at the current market of more than 300,000 yuan, China brand has only an ideal performance in sales volume, and the road ahead is still very long.

"BYD Seagull Interior"

　　In 2023, BYD launched a series of champion models, aiming at continuously improving the product strength and constantly exploring the selling price. The best-selling models Qin PLUS, Song PLUS, Yuan PLUS, Han and Song Pro all have champion models, "99,800 yuan Qin PLUS champion version to make friends!" What’s even more outrageous is that even at this price, there is still a big promotion. For example, Qin PLUS has a limited-time discount of 10,000 yuan on the basis of 99,800 yuan. At the same time, BYD also launched a low-cost electric car Seagull this year, which can achieve a battery life of 405km under CLTC conditions with less than 100,000 yuan. Although the sparrow is small and complete, who can not love such an exquisite car? It sold 50,000 units in December alone.

　　Behind the price reduction, the net profit of the company has not been affected. In the third quarter of 2023, BYD still achieved a net profit of 10.413 billion yuan, an increase of 82.16% year-on-year. The net profit is still much higher than that of other car companies of China brand. This is due to BYD’s advantages in self-developed technology and spare parts supply. BYD’s self-produced spare parts, including batteries and other core three, can control the cost lower and have its own core technology at the same time.

"BYD Blade Battery"

　　Different from many car companies, BYD started to lay out the supply chain system as early as 20 years ago, and started to make semiconductors in 2002. Today, Huawei’s supplier cooperation model is popular. In fact, BYD laid out earlier. A self-developed system can make the industrial chain safer and lower in cost. At the same time, BYD adopts the mode of vertically integrating the supply chain. In the period of industry change, BYD and suppliers can work together. This independent supply chain system is not achieved overnight, but accumulated in the past 20 years, and it is difficult for competitors to learn, which has made BYD’s enterprise virtuous circle.

　　In 2023, BYD also let foreign friends put up their thumbs. Although BYD’s passenger cars only went to sea for about two years, it was different from many China car companies that focused on third world countries. BYD took the lead in entering the European market and Japanese and other developed countries.

BYD booth at Munich Auto Show 2023

　　The crowds at the BYD booth at the Munich Motor Show in 2023 were impressive, and the Japanese media’s admiration for BYD at the Tokyo Motor Show was equally unforgettable. Compared with the serious involution in China market, the penetration rate of new energy in overseas markets is not high, and there are more opportunities. BYD takes the lead in entering the developed markets. On the one hand, Europe will be more receptive to new energy vehicles. In addition, BYD also has branches in Europe and America, and it knows more about the local area. Li Yunfei said, "BYD should show an international image, a high-tech company and the concept of focusing on the sustainable development of mankind overseas."

　　Of course, compared with SAIC and Chery, which have been "going out" for many years, BYD has just started to go out to sea in the field of passenger cars, and it still needs to brand and build sales channels.

● Outlook for 2024

　　Technology-driven has been deeply rooted in BYD. In 2024, BYD will focus on the weak links, and by going up one flight of stairs will focus on the superior projects. In the future, BYD will release core technologies every year, striving to make the product experience better.

　　At present, BYD’s weakest link is the high-level intelligent driving assistance. When the new car-making forces, even the products of 200,000 yuan, are rolling in high-level intelligent driving, BYD’s high-level intelligent driving assistance systems in cities and high-speed road conditions are not equipped, and they still stay on the basic L2-level automatic driving assistance. In the era when high-level intelligent driving assistance was still in PPT, Wang Chuanfu once said that "unmanned driving is a fool of ordinary people, and it is useless at all."

　　As the industry began to compete for intelligence, when it was actually in actual combat, Wang Chuanfu began to recruit people in the field of autonomous driving. At present, BYD has the largest intelligent R&D team in the world, and its R&D investment in the intelligent field has accumulated over 100 billion. In fact, advanced intelligent driving assistance can not only enhance the sense of science and technology, but also become a way to increase profits through optional opening.

Tengshi N7 Intelligent Driving Hardware

　　And all this will happen soon in the future. At the press conference of Tengshi N7 last year, the official has indicated that high-speed NOA will be realized in Q4 of 2023, high-speed obstacle avoidance, large curvature ramp driving, cross-floor parking and other functions will be realized in March of 2024, and NOA driving support in 20 cities is expected to be realized in 2024. Although we haven’t seen Tengshi’s high-speed NOA online yet, it is expected that we will get good news in a few days.

"Tengshi N7 Intelligent Driving Scheme"

　　Of course, if you want to experience BYD’s high-speed NOA, urban NOA, HPA memory parking, AVP parking service, etc., you must add 10,000 yuan to choose a high-end version of the intelligent driver assistance system, and you will get two laser radars and a 254TOPS computing NVIDIA Orin-X chip. The standard driver assistance system has no lidar and only 10TOPS chips. BYD is trying to catch up with new forces in intelligent driving. As for the result, we can look forward to it together.

　　In 2024, BYD will also release the fifth-generation DM technology, namely DM 5.0. The new technology is expected to be applied to a new generation of Chinese cars. At present, there is no official information spoiler, but combined with BYD’s patent application for hybrid system in 2021, there is some speculation that a set of double-row star gears may be added to the new system, which may be adjustable in two gears.

"BYD Hybrid System Patent Application"

　　The conclusion from the application information is that the new hybrid system has smaller size, lower cost, faster mode switching and better fuel economy. In other words, the new hybrid system can make dolphins and other models have DM models, and the fuel economy of DM-i models will be lower than that of the current models, and the product pricing will be lowered. At the same time, the system will be more intelligent and can meet more working conditions. Of course, none of the above has been officially confirmed, and we still need to wait for the official to reveal the answer.

　　According to Wang Chuanfu’s vision, "In the next 2-3 years, BYD will use crowd tactics and a large number of R&D personnel to maintain the ability of disruptive technology iteration, with engineers, vertical integration, market strategy and scale advantage. As for a certain technology, it is not the most important for BYD. There are many fish in BYD’s technology pool, and one is fished out when it is critical. "

　　So in 2024, what new products will we see in terms of new models?

Quanxinhan

"Brand-new Chinese imaginary map (source: Zhidian Travel)"

　　Judging from the information on the network, first of all, the brand-new Han took the lead in carrying DM 5.0 and used a brand-new hybrid special chassis. Because the hybrid mechanism is smaller, the shape of the new Han may be more streamlined and dynamic, and it may be upgraded to a front double wishbone suspension that pays more attention to handling. At the same time, the pure electric cruising range of the new car is also expected to increase. The interior is also expected to have a new upgrade. From Song L, we can see the progress of BYD’s interior design, and it is expected that the new Han will have a more eye-catching design. Finally, in terms of model size, according to some spy photos in the early stage, it can also be judged that the size of the new car will be longer and the seating space will be more comfortable.

Qin l

"Qin l spy photos"

　　Qin L is another model that is expected to be equipped with DM 5.0 technology. At the same time, like Song L, it will launch a pure electric model with CTB battery body integration technology based on E platform 3.0. Judging from the spy photos currently mastered, its appearance and interior will be the same as Song L, with a more dynamic and concise design and a coupe-style design, while the interior will have a larger instrument panel and central control screen. In terms of driving control and endurance performance, there will be better performance.

Meta UP

"yuan UP declaration map"

　　Yuan UP will be a brand-new small SUV, smaller than Yuan PLUS, and it is a pure electric SUV with a maximum power of 130 kW. Its model size is 4310/1830/1675mm, and its wheelbase is 2620 mm. At present, the new car has been shown in the declaration drawing, which adopts a completely different design style from the previous meta-family. The suspended roof, with a more lively appearance, presents a cross-border wind as a whole.

Sea lion 07 EV

『Sea lion 07 EV spy photos』

　　Sea lion 07 EV has been unveiled at the Guangzhou Auto Show in 2023. It is positioned as a brand-new medium-sized SUV with an estimated price of 200,000-260,000 yuan, which is expected to be listed in the first half of the year. Also from e platform 3.0, it adopts marine aesthetic design, locates coupe SUV, and further optimizes the design aesthetics of seals. Judging from the published interior spy photos, it is expected that it may be close to the interior design of Song L.

Small sports car

『Imaginary map of BYD sports car (source: arrogant Wei Xiaohua)』

　　As early as 2009, BYD built the first sports car S8, which is also a hardtop convertible. Fifteen years later, in addition to looking up to U9, BYD brand will also launch a sports car. At present, there is no news of new models, but some imaginary pictures of new cars have been exposed on the Internet, and we can see that their shapes are quite cool, even the feeling of looking up at U9. After the GT has received a certain degree of attention, I believe that the market segment of civilian sports cars will also attract the pursuit of many young consumers.

Tengshi two flagship cars

　　Tengshi once said that it is expected to release two flagship cars that benchmark Porsche Panamera and replace Mercedes-Benz S-Class at the end of 2024, which should take the luxury sports route and the luxury and comfort route respectively. At present, the flagship car that replaces Porsche Panamera has been exposed, which adopts the design of hunting model, with slender body size, amazing car length and wheelbase, or will be positioned as a large car.

Equation Leopard Leopard 8

『Equation Leopard Leopard 8 spy photos』

　　The concept car of Equation Leopard 8 has been unveiled before. It is positioned as a large SUV and will still be a hard-core SUV. From the spy photos, its model size will be very huge. It is expected that the new car will be designed with three rows and seven seats, and there will be a spare tire at the tail. The lines of the whole body are quite tough. Leopard 8 will be built on BYD’s new DMO super hybrid off-road platform, equipped with a hybrid four-wheel drive system, and will also be equipped with Yunqi -P intelligent hydraulic body control system.

Look up at U6

"Look up at U6.Spy photos (Source: Zhidian Travel)』

　　Looking up to U6 will be a medium-sized and large-sized car of looking up to the family. It has the same lowest drag coefficient of 0.195Cd as Xiaomi SU7 in the industry, so it will have outstanding performance in battery life, which may exceed 1000 kilometers. It has an iconic C-head lamp design similar to looking up at U9. The whole body is streamlined and dynamic, equipped with laser radar, and the tail is a coupe shape. The interior of the new car will be equipped with a huge central control screen, and the screen size of the dashboard is not small. It is expected to be equipped with easy quad platform technology and launch a four-motor version.

Look up at U9

"Looking up at U9"

　　Looking up at U9, everyone is familiar with it. It is a super sports car with an acceleration of 0-100km/h to 2 seconds. It is also an easy Sifang technology platform product, and its estimated price is one million. Looking up, U9 will be equipped with a four-motor system. The maximum power of the four motors is 240 kW, and the comprehensive power is 960 kW, that is, 1306 HP. Its cloud -X technology can provide powerful chassis control capability. In terms of vehicle size, the length, width and height are 4966/2029/1295(1338)mm and the wheelbase is 2900mm respectively.

"BYD pickup spy photos (Source: Xiao Di Dilink)"

　　In addition, you may be more concerned about BYD pickup truck, but the previous news shows that the car may be the first to be launched overseas. At present, BYD’s strategy of going to sea is mainly based on vehicle export in the early stage, and the next stage will still be to build factories overseas. For example, BYD has already set up factories in Thailand and Hungary.

　　In Thailand, the EV 3.5 plan formulated by the local government, as long as foreign car companies can set up electric car factories in Thailand before 2027, can give imported cars up to 40% tariff reduction in 2024-2025, and can also reduce the consumption tax by 2%. Building factories overseas can not only reduce tariffs, but also reduce costs appropriately, and at the same time integrate into the local area to localize the models.

　　In Hungary, BYD has a local bus production base, and Hungary is located in the center of the European continent, which is an important transportation hub and has a certain automobile industry foundation. BYD’s goal is to occupy 1/10 of the sales of pure electric vehicles in Europe by the end of 2030 through the Hungarian factory and become the first electric vehicle brand in Europe.

"2023 Tokyo Auto Show Visitors Visit Tengshi D9"

　　Wang Chuanfu said, "BYD will also focus on countries without local automobile brands in the short term, enter the local area to build vehicle production plants and transport parts to the local area, which can reduce freight and tariffs." For overseas markets, the market with government subsidies for new energy will develop faster, and BYD can occupy the market faster.

　　At the same time, in the future, BYD will also rapidly develop offline stores and bring more products according to the rhythm. For example, in Japan, BYD will find many veteran dealers to shop. These dealers have experience, teams, funds and contacts, and can quickly build stores and launch them. At present, BYD has planned to open 100 stores in Japan by 2025.

Write at the end:

　　At the ceremony of BYD’s 5 million vehicles rolled off the assembly line in 2023, Wang Chuanfu choked several times in his affectionate speech. Just like when Musk was interviewed by the media in that year, behind the glory of the giant, there were countless nicknames, pressures and pains, and he was even regarded as an alternative, not a normal person. This heartfelt sadness can only be realized by personal experience, just like many Olympic champions will burst into tears when they stand on the podium.

　　In 2023, BYD ushered in a new high-light moment in the China market. With an eye to the future, while expanding its scale, BYD still needs to have a longer-term plan in terms of technology and management. In the increasingly involuted China market, BYD’s past people-sea tactics are no longer applicable, but now BYD needs more sophisticated talents to improve its brand image and the whole team. We have seen the transformation of BYD. The number of employees with a master’s degree or above has reached 10,000, which will help BYD make new breakthroughs in technology and become a global leader in the field of new energy.

● If the budget is enough, it is recommended to give priority to the 1.4T power combination model, which has more power and better reliability.

Third, talk about how to choose.

1. Which groups are suitable for?

① Leather ~ fuel-saving ~ durable ‖ Suitable for ordinary people who practice walking at home and pursue stability and reliability.

② The car body is stable and up-to-grade ‖ suitable for people with business reception needs.

③ The chassis is made of solid materials, and the control is good ‖ It is suitable for people who have a certain pursuit of control, and comprehensive road sections can easily cope with it.

2. Some suggestions that must be known before buying

① It is suggested to proceed cautiously. Before 2014, the failure rate of vehicles equipped with 7-speed dual-clutch gearbox, especially the congested urban roads, is really high.

(2) It is suggested to avoid vehicles with skylights when starting sagitar before 2012, because the skylight leaks is a common problem.

③ It is suggested to proceed with sagitar carefully during 2012-2015, which may lead to the risk of shaft breakage. Check the 4s records before buying to see if there is any recall and rectification record. If there is no rectification, try to bypass it.

(4) In recent years, the market of new cars has changed greatly, so it is not recommended to buy second-hand quasi-new cars, and the cost performance is not high, which may not save money.

3. Budget within 30,000 yuan

This budget can basically buy all the models of the first generation sagitar.

② If the car is older and wants to be fuel-efficient and durable, it is recommended to give priority to the model.

③ It is suggested to avoid vehicles with 1.8T/1.4T power combination as much as possible.

4. 30,000-50,000 budget

(1) can buy the second generation of early models in 12-15 years.

(2) It is suggested to find out the record of Chu Weibao before buying, and see if it has been recalled by the manufacturer for rectification before, otherwise proceed cautiously.

③ This budget recommends a power combination of 1.6, or a manual transmission model with other displacement.

5. 50,000-70,000 budget

(1) You can buy the later-redesigned models in the period of 15-18 years, with high cost performance.

② If the budget is enough, it is recommended to give priority to the 1.4T power combination model, which is fuel-efficient and durable, with stronger power and better speed increase.

6. 70,000-110,000 budget

① You can buy the new sagitar in 19-23 years.

② For ordinary household transportation, if there is no high-speed demand and excessive power demand, it is enough to buy a 1.2T model.

380 thousand or so budget to buy a new sagitar, the cost performance is relatively high

4 With a budget of 90,000 yuan, it is not recommended to buy sagitar, which is not cost-effective. At this time, either get on the new car directly or consider other models with higher cost performance.

　　Cctv news(Reporter He Chuan) Recently, the "dark circles" of some giant pandas in chengdu research base of giant panda turned white, which attracted the attention of the national panda powder.

　　"Dark circles" is the "signboard" of the national treasure giant panda. What causes it to turn white? Can the "dark circles" of giant pandas change back? On January 25th, Yang Guangyou, a professor at the College of Animal Medicine of Sichuan Agricultural University, was interviewed by a reporter and gave detailed answers to the questions that netizens were most concerned about. It is understood that Yang Guangyou is one of the members who participated in the "rescue" of the giant panda "dark circles".

　　The "hair loss" of some giant pandas is actually caused by sampling.

　　At the end of 2017, careful "Panda Powder" found the recent photos and live videos of "white eyes" of online celebrity giant pandas Qiyi, Qifu, Xiaoya and Yongyong in chengdu research base of giant panda on social media. From a photo published by Sichuan media, it can be clearly seen that the "dark circles" of this giant panda have obviously turned white and their hair has fallen off.

　　Chengdu research base of giant panda staff said in an interview with the media that Sichuan’s humid and humid environment is more conducive to bacterial reproduction than other dry areas, and some giant pandas are sensitive in constitution, so mite infection is very easy to occur. The infection caused by the suspected mites is not explosive, but sporadic and not contagious. Currently living in chengdu research base of giant panda, there are no more than 10 giant pandas with eye depilation.

　　Yang Guangyou told the reporter: "We have recently paid attention to three giant pandas with serious clinical symptoms ‘ Yongyong ’ 、‘ Qiyi ’ And ‘ Xiaoya ’ Anesthesia was performed, and skin samples around the eyes were scraped and sent to the parasitology laboratory of Sichuan Agricultural University for PCR detection of demodex, and the test results were negative. In order to further these ‘ Mite eye ’ The individual was diagnosed, and the base invited me to have a bedside examination. At present, the test is being repeated. Once the PCR is positive, the base will use the screened effective drugs for treatment. "

　　Yang Guangyou said: "According to my observation, the condition of the giant panda in the base is mild, because only the lesions appear around the eyes, and the spirit and appetite are normal, and there is no malnutrition or weight loss, but the giant panda is ‘ National treasure ’ , so the condition was artificially amplified. According to the symptoms and signs, at present, it can only be said that mite infection is suspected. These giant pandas were scraped off due to sampling, and some netizens thought that the hair loss was aggravated, which was actually caused by sampling. "

　　"Saving" the giant panda "Black Eyesocket" is in action.

　　How do these giant pandas suspected of being infected with mites recover? How long will it take to change back to "dark circles"? These two issues are the most concerned by netizens.

　　Yang Guangyou said that if it is diagnosed as mite infection, you don’t have to worry too much. It is just a very common skin disease, and domestic pets and humans have different degrees of infection. "acariasis is one of the common ectoparasitic diseases of giant pandas. The main pathogens are scabies, itchy mites and demodex. Its clinical symptoms are itching, scabbing, depilation and skin thickening. Ivermectin and Serratin have achieved good therapeutic effects on scabies and itch mites. The appearance of the giant panda at the base as claimed by netizens ‘ Mite eye ’ Veterinarians began to investigate the etiology and etiology more than a year ago, focusing on the detection of demodex, fungi and vitamins and trace elements, but the cause has not been identified. " Yang Guangyou said.

　　Yang Guangyou said that apart from parasitic infection, there are many reasons that lead to animal body depilation, such as lack of vitamins and trace elements. At present, experts are also looking for possible causes from these aspects, and finding the cause can be targeted for treatment.

　　Finally, Yang Guangyou said, "If it is diagnosed as mite infection, the base has screened out Isoxazoline (trade name BRAVECTOR, Afoxolaner, etc.) and MilbemycinOxime, and made safety tests. As long as the right medicine is given, the hair will grow back quickly after treatment. ‘ Dark circles ’ Come back, netizens don’t have to worry too much. "

　　China Network October 12 (Reporter Lin Yiren) On October 11, the 2021 National Cyber Security Publicity Week Cyber Security Technology Summit Forum was held in Xi ‘an. Many experts closely follow the theme of the times, focus on the hot spots and difficulties in the field of network security, and express their views.

　　Strengthen the overall planning of national cyberspace security development

　　The rapid development of new technologies and applications such as 5G, big data, artificial intelligence and the Internet of Things has profoundly changed people’s production and lifestyle, and has become an important driving force for reconstructing a new pattern of economic and social development. Cyberspace brings great convenience to people, but at the same time, the threats and risk loopholes of network security are increasingly prominent.

　　David moses, an academician of China Academy of Sciences and a researcher of Academy of Military Sciences, shared the new changes in cyberspace security situation and the new trend of network security technology industry. In his view, under the background of accelerating the construction and application of new infrastructure and cloudization of IT infrastructure, the new concept and new architecture of network security represented by "zero trust" and "active defense" have been accelerated; The development breakthrough of artificial intelligence technology and its application in the field of information technology will promote the innovation, development and application of network security defense technology, and promote the intelligent upgrade of defense technology. At present, it is difficult to deal with complex threats by relying solely on product stacking. It has become a development trend to form a management closed loop through network security services, and the demand for network security services is constantly improving. The ecological environment of network security industry is improving day by day.

　　David moses suggested to raise security awareness, further strengthen the overall planning of the national cyberspace security development, strengthen research reserves, and timely adjust the top-level design of China’s cyberspace security development, the strategy and tactics of cyberspace international game, the technological innovation of cyber defense, and the response strategy of cyberspace threats. It is necessary to further increase the core technology innovation and industrial support of network security, strengthen the research on cutting-edge technologies such as "zero trust", and accelerate the research and development of network security system based on the framework of developing safe operation, active immunity and zero trust. Strengthen the role of artificial intelligence technology in empowering network security, and strengthen security technology research in satellite Internet, quantum communication and other fields. At the same time, pay attention to the output of cooperation between production and education, enhance the intensity of subject education, and further accelerate the gradient cultivation of network security professionals. Improve the network security vocational training standards and certification rules, and cultivate practical network security talents.

　　AI empowerment helps network security personnel training.

　　"At present, the world is in an era of great change with information technology as the core, and AI has brought new changes in the training of network security talents." Yang Zongkai, president of xidian university, said that AI has given new capabilities to network security, requiring security talents to skillfully apply AI; The security problems brought by AI itself require security talents to have a deep understanding of AI; AI+ education empowers personalized network security personnel training.

　　Combined with xidian university’s exploration, Yang Zongkai believes that in response to the new changes brought by AI to the training of cyber security talents, we should actively break the fence thinking, integrate production and education, and build a more open cyber security training system. In response to the profound changes in the demand for cyber security talents, we should take the initiative to change, reconstruct the educational environment, the AI+ security curriculum system, the teachers’ ability standards and the ability evaluation system, and create a new AI+ education format for cyber security.

　　"A new form of AI+ network security education that is student-centered, moral education first, ability first, connected, open, shared and personalized is taking shape in Xidian. AI technology is having an important impact on the cultivation of cyber security talents. AI+ education promotes the formation of a new educational form of cyber security. Let us work together to create a safer cyberspace with the power of AI+ education. " Yang Zongkai appealed.

　　Implement laws and regulations related to cyber space security as soon as possible.

　　Guan Xiaohong, an academician of China Academy of Sciences and director of the Department of Electronics and Information Science of Xi ‘an Jiaotong University, has long been committed to the research in the fields of economy and security of complex networked systems, optimization of power, energy and manufacturing systems, cyber space security, and information physics integration system including its comprehensive security.

　　Guan Xiaohong said that cyberspace refers to a digital virtual space composed of data, computing and network, not just cyberspace. Cyberspace has become the fifth territory of the country after land, sea, air and sky. Like other territories, cyberspace must also reflect national sovereignty, and ensuring the security of cyberspace means safeguarding national sovereignty.

　　Cyberspace security system includes network security, information security, content security, system security, CPS comprehensive security and data security. Among them, data security is an important content of cyberspace security, which is closely related to network security, information security, system security, content security and CPS security. It is necessary to solve the security problems of data acquisition, storage and use, realize multi-dimensional and three-dimensional data security protection, and safeguard national security.

　　In Guan Xiaohong’s view, the future of data security depends on the new paradigm of combining management and technology. It is suggested to implement the relevant laws and regulations on cyber space security as soon as possible and establish an autonomous and controllable data security ecosystem. At the same time, it is necessary to accelerate the development of key technologies for cyber space security and build a life-cycle data security architecture and protection mechanism.

　　A few days ago, Aika Automobile obtained a group of road test spy photos of the BMW i4 model photographed by netizens in China. The BMW i4 is positioned as a pure electric four-door coupe, equipped with the fifth-generation BMW eDrive electric drive technology. The acceleration time of 0-100km/h is only 4 seconds, the top speed exceeds 200km, and the cruising range can reach 590 km (under WLTP). It is reported that BMW i4 will be officially listed this year.

　　In terms of appearance, the BMW i4 basically continues the previously released concept car, but some details have been changed in a more mass production way. The most obvious adjustment of the front face is that the headlights are replaced with similar shapes of the 4 series. The large-scale closed kidney air intake grille is consistent with the concept car, and the I-style blue decoration around the grille. It further highlights the special dynamic identity of the car.

　　Viewed from the side, the BMW i4 basically continues the design of the concept car, but it has been adjusted in some line designs, making it sharper and more dynamic. The slip-back shape and slender figure further improve the powder absorption rate of this four-door coupe.

　　On the tail, the overall design of BMW i4 also continues the concept car, but it also changes in some details. For example, the BMW i4 taillights also adopt the same design style as the 4 Series. In addition, the tail diffuser similar to the fuel truck further enhances the sense of movement of the tail. In the power system, the BMW i4 will be equipped with the fifth-generation BMW eDrive electric drive technology, with a maximum output of 390kW(530 HP). It is also equipped with a battery pack with a capacity of 80kWh, with a cruising range of 590 km (under WLTP), an acceleration time of 0-100km/h of only 4 seconds and a top speed of over 200km. In addition, the maximum charging power of the new car is 150kW, and it takes only 35 minutes to charge the battery to 80%. (Source: Weibo netizen mniykx0920)

　　Su Zhi is known as the "gas pass" in Guijie. During the National Day, he and his colleagues conducted daily gas safety inspections.

　　Su Zhi, the vice captain of Beixinqiao Street Comprehensive Administrative Law Enforcement Team, was called "Gas Pass" in Guijie. Yesterday evening, he and his team members came to several catering units in Guijie that needed to be "looked back" according to the analysis of the big data platform of urban management comprehensive law enforcement, and re-examined the gas safety, domestic waste classification and three bags in front of the door. He said: "The introduction of big data platform has improved the efficiency of law enforcement, and the law enforcement team has also carried out co-governance work, which has improved the gas safety awareness of merchants and implemented the responsibility in place."

　　In order to create a good national day holiday and travel environment for the broad masses of the people, the Municipal Urban Management Law Enforcement Bureau deployed the city’s urban management law enforcement departments to strengthen law enforcement inspection during the holiday season, focusing on ensuring the core area and surrounding areas, tourist attractions, bustling commercial areas and characteristic blocks, major transportation hubs and other places, and focusing on solving outstanding environmental problems to ensure the safe operation and stability of the capital and a clean and orderly environmental order. According to the statistics of the Command Center of the Municipal Urban Management Law Enforcement Bureau, on October 1st, the urban management law enforcement departments of the whole city investigated and dealt with 673 illegal acts, and the city’s environmental order was good.

　　Eliminate hidden dangers at the beginning

　　Prevent problems from not "burning"

　　The festive Guijie Street is busy and orderly, full of "urban fireworks". Over the years, there have been no gas safety accidents in Guijie Street, which has brought a safe and peaceful business and dining environment to merchants and diners. Su Zhi said: "Holiday protection is very important, and more efforts have been made in peacetime to eliminate hidden dangers at the beginning and prevent problems before they happen ‘ Burn ’ , is the motto of my colleagues and me. "

　　"To do a good job in gas law enforcement, all parties need to work together, think in one place and make efforts in one place. In particular, we must let merchants understand that strict requirements and strict law enforcement are for the common interests of everyone on this street." Su Zhi introduced that the comprehensive administrative law enforcement team of Beixinqiao Street has carried out "co-governance" with the merchants in its jurisdiction, helping all units to ensure "self-governance", assigning responsibilities for regular self-examination and self-correction, and establishing the awareness that all employees are safety officers. He said: "Merchants themselves have also selected and recommended excellent models of gas use, and everyone has learned from each other. Some merchants have begun to ignore them, and neighboring merchants will give them pressure, because as we all know, this has destroyed everyone’s common business.

　　"In the inspection, we now use the comprehensive big data platform for urban management law enforcement. Every time, with the inspection and input, we form data analysis of the area, which street and which area have high incidence of which key problems, and which gas users have high incidence of which problems. It is clear at a glance and improves the efficiency of law enforcement." Su Zhi introduced that big data analysis can enable law enforcement teams to better combine carpet surveys with key law enforcement.

　　"Doing instead of training"

　　Bring the learning classroom into the law enforcement scene.

　　In order to implement the principle of "whoever enforces the law will popularize the law", Su Zhi also cooperated with the Guijie Management Committee and the gas company to take "online anytime+offline regularly" training for all gas users. He himself became a "gas expert" and answered all kinds of gas safety regulations and policies, especially the common sense, tips and emergency handling in the face of accidents.

　　Su Zhi said: "The Municipal Bureau and Dongcheng District Bureau regularly organize us to conduct on-the-spot training at the law enforcement site every year. The law enforcement site is a learning classroom, and the immersive improvement is rapid."

　　It is understood that, in view of the strong professionalism of gas safety special law enforcement, the Municipal Urban Management Law Enforcement Bureau brought the learning class to the law enforcement site according to the actual needs of the grassroots, sent the backbone of gas safety special law enforcement business to the law enforcement point, and jointly carried out law enforcement inspections with grassroots comprehensive administrative law enforcement team members, on-site guidance and exchange of experience, and taught gas safety special law enforcement skills. Through experiential and interactive teaching, improve the knowledge reserve of gas safety special law enforcement of grassroots law enforcement team members.

　　In order to facilitate learning, the Municipal Urban Management and Law Enforcement Bureau has also produced a short online course and teaching video on gas law enforcement standards for non-resident users. First-line players can watch it in real time through the network and mobile phones, and quickly grasp the key points of gas law enforcement. At present, the cumulative number of clicks on the course has reached more than 50,000.

　　Shi Yue, the captain of the Fifth Team of the Second Brigade of the Law Enforcement Corps of Beijing Urban Management Law Enforcement Bureau, is one of the main teachers of "training by doing". The Law Enforcement Team 5, where he belongs, is responsible for the overall guidance of the special business in the fields of gas safety and underground pipeline protection in the city’s urban management law enforcement system and the law enforcement work of the corresponding municipal urban management authority. As the captain of the Fifth Team, Shi Yue is proficient in gas safety law enforcement, with rich experience and strong sense of responsibility. No matter whether it is holidays, bad weather or late at night in winter, once there is an emergency in gas safety, he always takes the lead and rushes to the scene to investigate and collect evidence at the first time. He always keeps a set of urban management uniforms at home, so that even if there is an emergency at rest, he can put on his uniform and rush to the scene.

　　On the National Day this year, he led the whole team to prepare the law enforcement inspection plan during the festival early. Relying on the comprehensive law enforcement big data platform, he selected key units found to have hidden dangers of gas safety problems in previous inspections for review to ensure that the problems were rectified in place.

　　"Gas safety law enforcement inspection is one of the key law enforcement projects of our urban management law enforcement department on holidays. Every year, I have to spend a few days at work during long holidays. Through repeated inspections, I have been prompted again and again to see that these users in restaurants are using gas. The process is becoming more and more standardized, and I feel that my work is not in vain. It is very gratifying." Shi Yue said.

　　Catch up with others.

　　The whole chain cracked down on gas safety violations.

　　While intensifying law enforcement on gas safety and strictly investigating hidden dangers, urban management law enforcement departments "catch up" with illegal gas clues such as the gas source of illegal liquefied petroleum gas stations found in the inspection, and improve the connection mechanism of case transfer with urban management, public security, market supervision, emergency management, fire rescue and other departments to jointly punish illegal acts.

　　Since the launch of the "100-day Action" for urban operation safety in the whole city, the Law Enforcement Corps of the Municipal Urban Management Law Enforcement Bureau and the Chaoyang District Urban Management Law Enforcement Bureau have inspected the clues of "black gas cylinders" in the previous period and found that there are suspected illegal liquefied gas tanks in a waste express truck, and 14 illegal liquefied gas tanks were seized on the spot; Changping District Urban Management Law Enforcement Bureau and the Public Security Detachment of the Public Security Bureau of the Joint District seized a place where zombie car was used as a mobile selling place for illegal gas cylinders, and 16 illegal gas cylinders and 1 set of inflating device were seized on the spot.

　　On the first day of National Day, the whole city
