Out of the ICU, but not ashore yet. This is the evaluation of Xpeng Motors’s 2023 financial report by many people in the industry.

On March 19th, the latest data disclosed by Xpeng Motors showed that in 2023, the company’s total revenue was 30.68 billion yuan, a year-on-year increase of 14.2%. In terms of delivery volume, Xpeng Motors delivered 141,600 new cars in 2023, a year-on-year increase of 17%.

Although both revenue and delivery have increased, Xpeng Motors has not yet got rid of losses. In 2023, the net loss of Xpeng Motors was 10.38 billion yuan, which was 13.6% larger than that of 2022 (loss of 9.14 billion yuan). The gross profit margin of automobiles for the whole year was -1.6%.

The adjustment was effective, but it did not get rid of the annual loss.

Throughout the whole year of 2023, Xpeng Motors’s financial performance improved in the fourth quarter of that year, but it was under pressure due to the performance in the first three quarters.

The financial report shows that in the fourth quarter of 2023, the gross profit margin of automobiles in Xpeng Motors was 4.1%, while in the third quarter it was -6.1%, and the gross profit margin turned from negative to positive. In 2023, the gross profit rate of automobiles in Xpeng Motors was -1.6%, and in 2022 it was 9.4%.

It is reported that although Xpeng Motors has adopted discount and preferential policies for its models in order to meet the year-end sales, the change of sales structure and the change of average bicycle price have made Xpeng Motors improve its gross profit margin. In terms of sales structure, the proportion of Tucki G9 with higher unit price increased from 7% in the third quarter of 2023 to 26% in the fourth quarter.

In terms of bicycle cost, in the fourth quarter of 2023, the bicycle cost in Xpeng Motors was 191,000 yuan (excluding the impact of deduction), a decrease of 11,000 yuan from the previous month. The reason is that although the price of the new Tucki G9 is lower than that of the old one, the gross profit margin exceeds that of the old one under the technical cost reduction. At the same time, the price of lithium carbonate continued to decline, which naturally reduced the cost of vehicles in Xpeng Motors.

In fact, the above data changes are the result of Xpeng Motors’s continuous adjustment for more than a year. Since October, 2022, Xpeng Motors has made adjustments in its organizational structure. Especially after Wang Fengying joined Xpeng Motors as president, he tried to achieve the goal of cost reduction by streamlining SKUs, eliminating inefficient stores, merging sales theaters and optimizing purchasing strategies.

According to the financial report data, "saving money" has become one of the key directions of Xpeng Motors in 2023. This year, the number of employees in Xpeng Motors decreased from 15,829 in the same period last year to 13,550. At the same time, in terms of R&D, Xpeng Motors only increased its expenditure by 1.2% in 2023, and the number of R&D personnel decreased from 6,313 in the same period last year to 5,401.

Thanks to various measures, although the situation in Xpeng Motors has improved, it is still not completely "out of trouble". According to the financial report data, in the fourth quarter of 2023, Xpeng Motors’s net loss was 1.35 billion yuan, compared with 2.36 billion yuan in the same period last year and 3.89 billion yuan in the previous quarter. In 2023, Xpeng Motors’s net loss was 10.38 billion yuan, while in 2022, its net loss was 9.14 billion yuan, showing an expanding trend.

He Xiaopeng, Chairman and CEO of Xpeng Motors, said, "Xpeng Motors has integrated the intelligence, powertrain and vehicle platform into a large intelligent platform, so as to realize the maximum common sharing among all vehicles. Platform-based R&D and scale effect not only reduce the supply chain cost and manufacturing cost, but also greatly improve the efficiency of R&D iteration, thus enabling Tucki to accelerate the goal of reducing costs by 25%.

Want to challenge BYD with smart driving?

Looking forward to the first quarter of 2024, Xpeng Motors expects its car delivery to be between 21,000 and 22,500, an increase of about 15.2% to 23.4% year-on-year; The total revenue will be between 5.8 billion yuan and 6.2 billion yuan, increasing by about 43.8% to 53.7% year-on-year.

Data show that from January to February this year, Xpeng Motors delivered nearly 12,800 new cars. According to the delivery guideline for the first quarter, the delivery volume of Xpeng Motors in March may be less than 10,000 vehicles.

Investors are also cautious about Xpeng Motors’s future sales prospects and profit plans. "In addition to paying attention to the sales prospects in the first quarter of 2024, investors are also interested in the ‘ that Xpeng Motors plans to launch next month; Cheaper ’ The detailed plan of the model sub-brand is full of curiosity. " Qu Ke, an international analyst at CCB, said.

He Xiaopeng revealed in the earnings conference call: "During the 2024 Beijing Auto Show, Xpeng Motors will officially launch a brand-new brand for the level of 100,000 ~ 150,000 yuan. The first model of the brand new brand will be listed and delivered in the third quarter of this year. "

Gu Hongdi, honorary vice chairman and co-president of Xpeng Motors, said that the new brand will be sold first from the C-end, and then sold in the B-end and other channels a few months after being recognized by consumers. "The new brand model will be successful if it sells more than 10,000 vehicles per month. At present, our production capacity can support this goal." Gu Hongdi said.

It is worth noting that for the market segment of 100,000 ~ 150,000 yuan, new brands such as Wenjie, Ideality and Weilai have not been involved, while traditional brands such as BYD and Geely have not formed the advantage of intelligent driving. Therefore, the industry believes that He Xiaopeng has successfully found the breakthrough point in the cracks — — Play new brands with cost performance, and play traditional brands with smart driving.

National business daily reporter learned that the first model of Xpeng Motors’s new brand will cancel the lidar to reduce the cost of intelligent driving. At the same time, according to He Xiaopeng’s financial report conference call, Xpeng Motors has excellent cost control ability in intelligent driving, and it is expected to achieve the goal of reducing the cost of intelligent driving by 50% in 2024.

However, some people believe that consumers who buy cars in the price range of 150,000 yuan pay more attention to the cost performance, and the ability of intelligent driving has not yet entered the top five decisive factors affecting car purchase. In 2022, Xpeng Motors once put the intelligent driving function in the urban area on the P5 model in Tucki, but the purchase ratio of the actual intelligent driving version was not high.

The number of sales stores will increase to 600 in the third quarter.

In He Xiaopeng’s view, from 2024 to 2027, the elimination of smart electric vehicles officially began. "Xpeng Motors will enter the big product cycle of launching more than 10 new models in the next three years. Together with globalization and upgraded models, the total number of SOP models will reach 30." He Xiaopeng said in the earnings conference call.

When talking about the impact of the intensive release of new products on old products, He Xiaopeng said that the first thing to do after Wang Fengying joined Xpeng Motors at the beginning of last year was to solve this problem. "In order to avoid ‘ Infighting ’ Xpeng Motors will try to avoid the same type of products and there will be fewer car categories. " He Xiaopeng said.

Xpeng Motors’s product planning is regarded as similar to Wang Fengying’s product strategy of "having more children and fighting" when he worked for Great Wall Motor. It is reported that at the beginning of this year, Wang Fengying led a new round of organizational restructuring in Xpeng Motors, which involved product planning. According to industry analysts, Xpeng Motors may sell these models in a way similar to BYD’s sub-network, which is what Wang Fengying is good at.

From the channel point of view, Xpeng Motors is also moving closer to the field that Wang Fengying is good at. It is understood that Xpeng Motors launched the "Jupiter Plan" in July last year, releasing the franchise authorization of dealers and transferring some direct stores in Xpeng Motors to dealers for operation. By December 31st, 2023, there were 500 stores in Xpeng Motors, covering 181 cities.

He Xiaopeng said in the earnings conference call that Xpeng Motors completed a round of channel upgrade in 2023, eliminated more than 130 stores at the end, and introduced more than 160 dealers through "Jupiter Plan". Most of the new dealer stores have been open since the end of last year. It is estimated that the incubation period will take 3-4 months, which will make a significant contribution to the overall sales from April.

In addition, the reporter learned that since the second quarter of this year, Xpeng Motors has set up a channel inventory for about half a month to speed up terminal delivery. "Xpeng Motors will further expand the sales network coverage and accelerate the channel sinking. It is planned that by the third quarter of 2024, the number of sales stores will increase to 600, and it will continue to expand after the listing of new brands to accelerate sales growth. " He Xiaopeng said.

It is worth mentioning that since Wang Fengying joined Xpeng Motors, He Xiaopeng gave full support and authorization to her work, which made the effect of Xpeng Motors’s adjustment appear initially. However, such achievements are only the beginning. Whether the reform led by Wang Fengying can finally help Xpeng Motors get rid of losses and successfully "land" remains to be answered by time and the market.

Topic: "Perception of China" in Israel.

　　1. RoshHashana The Jewish New Year is the beginning of the year of the Jewish calendar (lunar calendar). It is one of the most important festivals for Jews. During the festival, the whole country has a two-day holiday. In the church, the horn was blown to talk to God, hoping to get God’s blessing. Friends meet to say "ShanaTova". According to tradition, people eat apples dipped in honey during the New Year, which indicates that the new year is sweet and beautiful.

　　2. YomKippur Yom Kippur is the tenth day after the Jewish New Year and is an important religious festival. Jews set this festival to confess to God and ask for forgiveness. Judaism stipulates that during Yom Kippur, you should fast for one day and pray and meditate in the church. When people meet in church, they wish each other a good evaluation from God. Yom Kippur ended with the melodious sound of horns in the evening.

　　3. Sukkot (Sukkot) This festival is to commemorate the life of living in a hut during the 40-year exile in Sinai after the Jewish ancestor Moses led the Jews out of Egypt. Therefore, the festival is in the harvest season, so it is also called the harvest festival. It is the main feature of every household to build a straw shed during the festival. The festival is celebrated for eight days. During this period, the IDF usually holds tank exhibitions in Tel Aviv’s municipal square.

Israel’s "Tent Festival"

　　4. SimhatTorah It usually takes a year for Jews to read Jewish classics. The Simhattorah is designed to celebrate the completion of reading, and the religious atmosphere is strong. This festival is a happy festival, so people (mainly Christians) should sing, dance and eat sweets. In the celebration ceremony, an essential item is to take down the scroll and walk seven times in your hand.

　　5. Hanukah Festival is to commemorate the success of Macabies’s uprising against the Greek invaders and the freedom of Jews. Legend has it that during the Jewish temple period, the seven olive oil lamps in the temple kept on burning, but they were eventually broken due to the destruction of the Greek invaders. After the victory of Macabies Uprising, I hope to rekindle the oil lamp. People looked around and found only enough olive oil for one day, but this olive oil was miraculously ordered for eight days until the new olive matured and new oil was added. Since then, Jews have set up festivals to commemorate this day when God helped them. This festival lasts for eight days, with two days off at the beginning and the end. The main celebration ceremony is to light a candle every day. Candlesticks with nine candlesticks are specially designed for this festival. Among them, the higher one in the middle is designed to ignite the other eight. At the beginning of the festival, people eat a special potato cake and then exchange gifts.

　　6. Purim means drawing lots. It is said that a wicked official hated a Jew who had offended him and set a date for killing all Jews by drawing lots. A Jewish woman who became a queen executed the wicked official and saved the Jews by playing around. During festivals, theaters usually put on plays about this story. People (mainly children) also wear masks about the characters in the story to attend the party, so some people call it the masquerade festival. At the party, people usually eat a special triangle cookie, which symbolizes the ear or hat of a bad official.

　　7. The Passover (Pessah) originated from the Bible Exodus. When Moses led the Jews out of Egypt to the Red Sea, he raised his staff to separate the Red Sea, and the Jews walked out of the Red Sea smoothly, while the chasing Egyptian army was submerged in the sea. The festival is celebrated for eight days, with two days off at the beginning and the end. Before the festival, people should remove all fermented pasta from their homes. During the festival, it is forbidden to sell and eat fermented food, and only a special unleavened pancake called Matsa can be eaten to commemorate the day when Jews could not eat fermented cakes when they left Egypt because of time constraints.

The traditional family feast of Jews during Passover.

　　8. Holocaust Remembrance Day (also known as Holocaust Remembrance Day) In order to commemorate the six million Jews killed by the Nazis between 1933 and 1945, the Knesset passed a decree in 1951, establishing the 27th of the Jewish calendar (April in Gregorian calendar) as Holocaust Remembrance Day. During the festival, orthodox Jews all over the world will fast for one day. Every family lights candles and reads the Jewish scripture Kadish. In Israel, an assembly or procession attended by the President, the Prime Minister and other important figures will be held to mourn the victims and celebrate the survival of the Jewish nation. At 10 o’clock in the morning, the national whistle sounded for two minutes, and the people stopped all work and stood in silence for the victims.

　　9. IDFMemorialDay This festival is set on the day before Independence Day to commemorate the soldiers of the National Defence Force who have given their lives to protect national security since the War of Liberation. At 8 o’clock the night before the festival, the national whistle sounded for one minute, and the people stood in silence. The National Defence Force also held an official commemorative ceremony at 8: 00 on the same day, attended by the President. At eleven o’clock the next morning, whistle again for two minutes.

　　10. IndependentDay was established to commemorate Israel’s independence in 1948. At eight o’clock the night before the festival, the Knesset held a formal celebration ceremony in Mount Herzl, Jerusalem, with the participation of parliamentarians and cabinet members. The ceremony included lighting 12 torches and firing salutes. The main activities on the day of the festival include a parade of the National Defence Forces, an air show, a reception hosted by the President for diplomatic missions and outstanding soldiers, an international Bible contest and an Israel Prize awarding ceremony. In addition, municipal governments also hold entertainment parties and set off fireworks.

Independence Day

　　11. Lagba-Omer means the 33rd day after the first day of Passover. According to legend, the Jewish rabbi Akiva organized Jews to recapture Jerusalem from the Romans on this day and lit a bonfire to inform the surrounding villages. Since then, Jews have commemorated the story of Achiwarabi and his recapture of Jerusalem with bonfires.

　　12. Jerusalem Day is a festival to commemorate Israel’s unification of Jerusalem in 1967. During festivals, there are usually grand celebrations in Jerusalem. The main celebration ceremony was held in front of the Western Wall at sunset the day before. Before the ceremony began, eighteen candles were lit to commemorate the soldiers who died in the battle to recapture Yecheng, followed by a thanksgiving ceremony. On the day of the festival, mass parades and other celebrations are held.

　　13. The forty-ninth day after the first day of Pentecost Passover is the day to commemorate Moses’ acquisition of the Ten Commandments. Therefore, the festival is catching up with the harvest of wheat and fruit, so it is also called the harvest festival. This is a happy festival, people should decorate their homes with flowers, and have a rich holiday meal with milk and cheese the night before the festival. Read the Ten Commandments on the festival day. At present, this festival has basically evolved into a children’s festival.

　　14. Tesha b ‘av means the ninth day of the Jewish calendar. According to legend, the Jewish temple was destroyed twice on this day. Jews commemorated this sad day with fasting.

　　Core reading

　　A few days ago, the Ministry of Science and Technology and other six departments issued a document, focusing on creating a number of major scenarios and expanding the application of artificial intelligence. High-level scientific research activities are one of them. Nowadays, China’s artificial intelligence technology is developing rapidly, and it has advantages in data acquisition, experimental prediction and result analysis. Life science, mathematics, chemistry, space science and other disciplines have embraced artificial intelligence. Rich application scenarios also feed back the development of technology and promote the upgrading of industrial wisdom.

　　From daily life to scientific research, today, China’s artificial intelligence technology is developing rapidly, and data and computing resources are increasingly abundant. Application demand is an important driving force for technological progress, and new technologies are often constantly improved and matured in "use". In order to promote the landing of artificial intelligence, a few days ago, the Ministry of Science and Technology and other six departments jointly issued the "Guiding Opinions on Accelerating Scene Innovation and Promoting High-quality Economic Development with High-level Application of Artificial Intelligence", focusing on creating several major scenes and expanding the application of artificial intelligence. High-level scientific research activities are one of them.

　　As a means of empowerment, how can artificial intelligence bring new research methods, and how can economic development inject "wisdom kinetic energy"?

　　Close integration helps scientific research to be more efficient and accurate.

　　Among many disciplines, life science research and artificial intelligence are closely integrated, and one of the hot directions is to predict protein structure.

　　Protein has a three-dimensional structure, and its primary structure (sequence) is composed of several amino acids in series. The three-dimensional structure determines the function of protein in cells, and many diseases are caused by the important protein structural abnormality in the body. Therefore, only by drawing a "three-dimensional map" of important protein in human body can we find the target of drugs acting on human body, thus developing accurate and effective new drugs.

　　Traditionally, scientists have observed the three-dimensional structure of protein by means of cryoelectron microscopy, X-ray and nuclear magnetic resonance, but this process is time-consuming, laborious and expensive. "Taking the cryomicroscope as an example, it costs tens of millions of yuan to arrange an observation platform, and it will take a long time for researchers to draw the protein structure." He Jingzhou, head of Baidu’s propeller bio-computing platform, said.

　　Due to the high difficulty, long experimental period and high cost, the number of three-dimensional structures of protein observed by traditional methods is very limited. In contrast, amino acid sequencing is much easier. Why can’t we predict the structure of protein based on the amino acid sequence? As early as 1972, American biochemist Christian anfinsen put forward this idea in his Nobel Prize acceptance speech.

　　It is precisely artificial intelligence that accurately predicts the three-dimensional structure of proteins from their primary structure. However, human beings have made slow progress in trying to analyze protein Group. It is explained that, on the one hand, because the existing biological data is small in quantity and low in quality, deep learning lacks enough samples; On the other hand, because the artificial intelligence algorithm is mature, it also needs a process.

　　In recent years, with the sharp increase of biological data and the optimization of artificial intelligence technology, scientists have established more accurate prediction models. In December 2020, in a competition, the artificial intelligence program "Alpha Folding" shined brilliantly, and its predicted results were similar to most experimental data. This proves that artificial intelligence has been quite accurate in predicting the structure of protein.

　　Nowadays, with the help of artificial intelligence, the work that may have taken several years can now be completed in a few minutes, and some protein structures that cannot be observed by traditional methods can also be analyzed.

　　It is understood that using artificial intelligence, researchers have predicted the structure of more than 200 million protein species of about 1 million species, covering almost every protein that has been recorded by the scientific community. This will have a great impact on the field of structural biology, which may lead to a paradigm change in life science research and enhance human understanding of life.

　　It has broad prospects and plays a role in many fields such as life science.

　　Artificial intelligence has entered the field of vision of life science research, and the demand of biomedical industry is an important driving force. According to reports, in the biopharmaceutical industry, the types of drugs that can be developed for every $1 billion invested have been declining. The research and development of new drugs is becoming more and more difficult, and the cycle is getting longer and longer. There is an urgent need for new methods to break through, and artificial intelligence has high hopes.

　　Not only does it accelerate the research and development of new drugs, but artificial intelligence is playing an important role in more and more fields of life sciences.

　　At the beginning of this year, a protein prediction model run by Chengdu Center of National Supercomputing helped the team of Wheat Research Institute of Agricultural College of Sichuan Agricultural University successfully analyze the molecular mechanism of PGS1 regulating seed development and affecting yield, and provided theoretical basis for cultivating high-yield and high-quality wheat materials. Researchers say that without artificial intelligence, it is difficult to make this breakthrough efficiently.

　　Researchers also try to introduce artificial intelligence technology into vaccine design. For example, compared with protein vaccine and DNA vaccine, mRNA vaccine has the advantages of fast mass production and good anti-infectivity, but its stability and immunogenicity are relatively poor. To make up for these shortcomings, researchers have been hoping to optimize the sequence design of mRNA vaccine to make it more stable and more immunogenic. With higher efficiency and lower cost, the intervention of artificial intelligence is expected to provide new ideas for vaccine research and development.

　　Precision therapy is also a stage for the application of artificial intelligence. Through the method of machine learning, in theory, artificial intelligence can decode the human immune system and explore the complex immune laws of some diseases more accurately, thus helping people understand diseases and develop therapeutic drugs and methods more efficiently and pertinently.

　　With the increase of human data and knowledge accumulated in new drug research and development brought by genomics research, and the continuous iteration of machine learning algorithms, industry experts believe that artificial intelligence has broad prospects in the field of life sciences. Some researchers even imagine to build a unified knowledge map by relying on a powerful biological computing engine and using a large amount of biological data to promote the understanding of life and health.

　　Rich scenes, pushing the application to a higher level.

　　Walking into life science research, artificial intelligence brings new methods, and it is also expected to open a new era of biomedical industry.

　　Experts in the industry said that seizing the new opportunities of intelligent drug design and strengthening the layout of artificial intelligence and biomedicine will help us to take the lead in the new track of new drug research and development.

　　Although artificial intelligence+biomedicine has developed rapidly, it has just started on the whole. He Jingzhou believes that the biomedical industry has a history of hundreds of years, with mature and perfect research processes, industrial chains and division of labor. The improvement of artificial intelligence is only some of them. "Biomedical is related to life and health, and the development of the industry should be steadily advanced, maintaining rationality and awe." Up to now, there is no new drug discovered entirely by artificial intelligence in the world. Some products developed by artificial intelligence are still a long way from the real market.

　　Seeing the advantages of artificial intelligence technology in data acquisition, experimental prediction and result analysis, mathematics, chemistry, materials science and space science have also embraced artificial intelligence.

　　The performance of lithium batteries varies with different material compositions. In response to the demand for lithium batteries in a variety of scenarios, researchers hope to design a suitable lithium battery system by optimizing the material combination.

　　"In the past, the design of material systems mainly relied on manual experiments, which was very inefficient." Zhang Qiang, a professor at the Department of Chemical Engineering in Tsinghua University, said that at present, he is leading the team to predict molecular properties with artificial intelligence, so as to find energy materials more efficiently and accurately and design more valuable and safer battery systems.

　　According to estimates, the scale of China’s artificial intelligence core industry exceeds 400 billion yuan, and the number of enterprises exceeds 3,000. Thanks to the strong demand brought by massive data processing and the experimental soil provided by rich application scenarios, China is at the forefront of the world in the fields of computer vision and speech recognition.

　　Experts in the industry suggest that it is necessary to give full play to the advantages of rich application scenarios in China to promote the application of artificial intelligence to a higher level. Creating a major scene around high-level scientific research activities will promote the application of artificial intelligence in China and inject "wisdom and kinetic energy" into high-quality economic development.

　　Beijing, June 8 th, "Geek All-Star Game" — — The offline final of the 3rd Tencent Capture The Flag (TCTF) started at 10:00 am on June 8th, Beijing time, at Shanghai West Coast Art Center. Twelve top international teams from eight countries and regions around the world gathered here to launch a 30-hour uninterrupted competition for the last place in the DEF CON CTF 2019 global finals of the "Hacker World Cup".

　　CTF is a popular form of information security competition. DEF CON CTF, the birthplace of CTF, is the CTF competition with the highest technical level and influence in the world, which is equivalent to the "Hacker World Cup". As the earliest and only wild card tournament authorized by DEF CON CTF in Chinese mainland for three consecutive years, TCTF has become one of the most professional and largest CTF events in China, with the "Starlight Glimmer" on the field, which brings together the world’s top geek teams and is called "Geek All-Star Game". The quality of the competition questions has also improved year by year. This year, a new competition question that is close to the forefront of the industrial Internet has been added. In the past three years, TCTF has accumulated more than 10,000 contestants, which has helped China’s new security forces to grow rapidly.

　　The number of participating teams has increased by over 30%, and the world’s top geeks have gathered in the "All-Star" lineup.

　　TCTF, as a professional CTF challenge initiated by Tencent Security, sponsored by Tencent Security College and Tencent Security Joint Laboratory, undertaken by Tencent Security Cohen Laboratory and co-organized by 0ops security team, has received positive responses from many top international teams and domestic universities. TCTF is divided into international competition for the whole world (0CTF) and RisingStar CTF for domestic universities. This year, 1,248 teams participated, and the number of participating teams increased by 30.4% year-on-year.

　　Teams shortlisted for this TCTF International Competition come from eight countries and regions, including China, Japan, South Korea, the European Union, Russia, Germany and Poland. Star teams gather and live in Starlight Glimmer. The Polish team Dragon Sector, which won the first and second TCTF International Competition in CTF TIME2018, the Balsn team in Taipei, China and the LC BC team in Russia, which ranked second in the world, and the traditional Korean team CyKor, etc., have covered recent years.

　　The competition in the final of Nova Invitational Tournament is equally fierce. There are three nova teams at home in Shanghai: Ph0t1n1a team of Shanghai Jiaotong University, and sixstars team and Whitzard team of Fudan University. There are also 12 famous teams, including Emmmm and Nu1L, the well-known joint teams of universities in China, and L team of xidian university, who have participated in the international professional CTF competition as challengers.

　　Add Yunan Quancheng and other frontier competition questions to train industrial Internet security talents in actual combat.

　　High-quality competition questions are a highlight of TCTF this year. The high quality of TCTF events has always been highly respected by the industry, and the 2018 international competition was also rated as the only CTF event in Chinese mainland by CTF TIME. This year, TCTF continued the international standard problem-solving competition system. Tencent Security Joint Laboratory and 0ops team of Shanghai Jiaotong University jointly issued the competition questions, deeply integrating the long-term offensive and defensive experience of both research teams, and trying to meet the actual requirements to the greatest extent. At the same time, this year, more innovative has integrated into the frontier hot fields such as AI, cloud computing, Internet of Things, etc., closely following the actual field and security demands of the industrial Internet, so that participants can challenge and experience the real-world network security attack and defense technology in the process of solving problems.

　　In order to let the audience better participate in this international top-level event, a visual big screen was used in the final scene to broadcast the wonderful offensive and defensive trends in real time, and the whole process was explained by the security researcher of Tencent Security Cohen Laboratory with rich practical experience. The contest also specially customized the "geek suit" to hide an interesting CTF test question. The audience and netizens who watched the live broadcast through Tencent University can participate in solving the "mystery" and win rewards such as cash and TCTF commemorative gifts.

　　It is worth mentioning that this year’s TCTF Offline Finals is dedicated to creating a geek culture with China characteristics. It will change the traditional award ceremony, and directly transform the arena into a Party site after the competition, so that the award ceremony will change "every second" and feel the geek culture with China characteristics.

　　Help the growth of young geeks in China and forge a "double-class" network security talent training platform

　　Different from the traditional CTF competition focusing on information security technology confrontation, TCTF also deeply undertakes the function of discovering and cultivating network security talents. After the precipitation of three TCTF events, Tencent Security strives to build a "double-first-class" network security talent training platform: by holding "first-class" CTF events to compete with the world’s top teams; Create a "first-class" talent training platform to accelerate the growth of the younger generation of cyber security talents in China.

　　At present, Tencent Security has formed a full-chain talent training model: relying on the TCTF competition platform, combining Tencent Security College and the Joint Security Laboratory to build safety talents, building a cooperation and exchange platform in Industry-University-Research, and forming an ecological chain of discovery-training-transformation. We will select potential students through TCTF platform, and then provide professional training opportunities and employment resources through the "words and deeds" of Tencent Security Joint Laboratory. At the same time, we will also have the opportunity to participate in top information security competitions at home and abroad, forming a complete talent training closed loop from theoretical education in colleges and universities to enterprise skills training to international competitions.

　　Tencent security "double first-class" network security talent training platform construction has also achieved phased results. At present, Tencent Security has established joint laboratories and research institutes with Guangzhou University, Beihang University, xidian university, Wuhan College and other universities to cultivate applied talents with strong practical ability and further enhance the research and development capabilities of universities and enterprises in the frontier information security technology field. In terms of events, the Tencent eee team, with Tencent Security Cohen Lab as the main force, successively won the online and offline champion of the Strong Net Cup, the champion of the first "Net Ding Cup" network security competition, the overall champion of the "Guard Net Cup" and the first place in the single prize in 2018. Tencent Security Team, which was jointly established by several departments, won both the "attack" and "defense" titles in the "2018 Guiyang Big Data and Cyber Security Attack and Defense Exercise", which is the most rigorous cloud security practical exercise in China, and defended Tencent security in the field of cloud services. Leading position; Shanghai Jiaotong University 0ops, Fudan sixstars and Zhejiang University AAA teams hatched by TCTF platform have also repeatedly entered the forefront in the three major competitions.

　　During the current TCTF, the third China University Information Security Talent Training Salon will also be held simultaneously, bringing together information security teachers from major universities across the country to offer suggestions and suggestions on network security talent training. In addition, TCTF2019 linked with TenSec Tencent Security International Technology Summit for the first time, opening up the connection between technical practicality and professionalism, creating opportunities for young geeks in China to communicate with the world’s top security cafes, and further improving the closed-loop mode of personnel training.

　　BEIJING, April 25 (Xinhua) Former legislator Li Ao released his latest masterpiece "Virtual 17" on the 25th. Li Ao joked at the press conference that there is an upper and lower age limit for reading this fantastic erotic novel, and people over 80 and under 18 can’t read it, otherwise it will be "frozen (unbearable)", like "Hao Longbin’s father (Hao Baicun) can’t read it".

　　According to Taiwan Province’s Dongsen News, today’s press conference of Li Ao’s new book was held in Fuhua Hotel. Li Ao said that although the book is not "illustrated", the story with 360,000 words and 600 pages thick is absolutely blushing and heart-pounding. A reporter asked, are most of the contents of this book real stories of "masters"? He did not change the old urchin’s personality, and said, "Of course, most of them are fake."

　　Li Ao also surprisingly said that the reason for publishing this "virtual seventeen-year-old" was that Taiwan Province had no literature at all during the Kuomintang ruling era, and some "monsters" who engaged in modern literature, such as Bai Xianyong and Wang Wenxing, came out. "I tell you, they were successful in life, failed in composition, and their articles were not well written. They learned the fur of foreigners and could not read their books, which was boring." Because "I look down on these people and talk to them.

　　Li Ao returned to his old job of writing and finished the novel "Virtual 17-year-old" after he stepped down as a legislator. He said that this book took five years, because it was delayed during his tenure as a "legislator" and he had time to concentrate on writing after leaving office.

　　"Virtual 17-year-old" narrates that a 17-year-old beautiful girl’s brain was implanted with a smart chip, and under the inspiration of a 67-year-old master of wisdom (the incarnation of Li Ao), she started the pursuit of spirituality and philosophy. The plot not only talks about ideas like "Beijing Fayuan Temple", but also has climaxes every 5 or 6 pages, so he also automatically classified the new book as a restricted level, added envelopes and affixed stickers.

　　Li Ao once said with a smile a few days ago that he is an out-of-date figure. Although the new book is very restricted, I am afraid it is still difficult to sell, but "I am rich and not afraid of losing money!" However, Li Ao was right in this sentence, because the visiting members of the mainland rich group, after seeing his high popularity in the mainland, left the stage and generously gave a big red envelope to cross-strait cultural exchanges, and decided to contribute 30 million yuan to support the establishment of a cultural academy in Li Ao to promote cross-strait cultural exchanges.

　　Holding a mobile phone is like playing a game. With just one button, an unmanned vehicle loaded with an intelligent "brain" can automatically find a parking space and automatically park in a nearby parking space.

　　In the smart factory, automobile production has tended to be unmanned, only to see the mechanical arm waving back and forth, running at high speed, and automatic robots shuttling back and forth to transport materials.

　　In the park, cleaning vehicles automatically run on the road, vending machines come and go at any time, and shuttle buses no longer need to be driven by people … …

　　This kind of scene makes the reporters of the Chongqing interview group dazzled by the online theme of "Going into the region to see the development and a new chapter of Sichuan and Chongqing".

　　The application of new energy vehicles is no longer limited to transportation. It can not only become our smart partner and provide us with thoughtful and caring services, but also become an intelligent mobile space and create new value for us. At present, the automobile industry is undergoing profound changes, and intelligent networked new energy vehicles have become the general trend. As an important automobile production base in China, Chongqing is accelerating the construction of a world-class intelligent networked new energy automobile industry cluster.

　　Master the core technology

　　"The new car in the future is no longer a simple means of transportation, but will gradually evolve into a ‘ with similar human wisdom and emotion; Intelligent automobile robot ’ 。” Han Sanchu, chief software architect of Changan Automobile, said in an interview with Chongqing interview group.

　　This idea has taken shape in the Deep Blue SL03 independently developed by Changan Automobile and the Aouita 11/011 jointly built by Changan Automobile, Contemporary Amperex Technology Co., Limited and Huawei based on CHN platform. Among them, AVATRUST extrasensory system, which comes standard in Aouita 11, includes three laser radars, six millimeter-wave radars, 12 ultrasonic radars and 13 high-definition cameras, which are jointly defined and developed by Aouita and Huawei, with a total of 34 intelligent driving sensors, which makes it the leader among new energy vehicles.

　　In January this year, the sales of Changan Deep Blue SL03 and Aouita 11 ushered in a "good start". The monthly sales of Changan Deep Blue reached 6,137 vehicles, ranking second in the domestic new energy vehicle delivery list only with a difference of 200 vehicles. Aouita Science and Technology announced on February 5th that its delivery has exceeded 2,000 units. At this time, it was only 38 days since its delivery.

　　The popularity of "Made in Chongqing" new energy vehicles is largely due to mastering the core technology.

　　For example, Changan Automobile Global R&D Center located in Liangjiang New Area has seven functions such as design, test and management, 12 fields such as simulation analysis, noise and vibration, passive safety, 180 laboratories such as hybrid power, air conditioning system and nonmetallic materials, and a world-leading data center built by cloud technology, and is setting up a software development team of 2,000 people and a new energy R&D team of 2,500 people. This indicates that Changan Automobile has entered the R&D 4.0 era of "independent innovation and global collaboration".

　　Starting the third venture since 2017 — — Since the innovation and entrepreneurship plan, Changan Automobile has achieved breakthroughs in two major areas: new energy and intelligence. Up to now, Changan Automobile has mastered more than 600 intelligent low-carbon core technologies; "Zero-fire" batteries and "seven-in-one" smart cores have all reached the leading level in the industry; The number of patent applications reached 4,745 in 2022 alone; The "National Key Laboratory of Intelligent Vehicle Safety Technology" jointly established with China Automobile Research Institute and Zhongke Xin was approved by the state, which is one of the only two national key laboratories in the automotive field.

　　In the past five years, Changan Automobile has invested a total of 57 billion yuan, and has built a global R&D layout of "six countries and ten places", and its R&D strength has been ranked in the forefront of China automobile industry for six consecutive years. At the same time, in recent years, Changan Automobile has seized a great opportunity to build a twin-city economic circle in Chengdu-Chongqing area, and intensified its supply chain layout in Sichuan and Chongqing. The supporting rate of enterprises in Sichuan and Chongqing is increasing year by year.

　　"This year, Changan Automobile will successively launch heavy products such as Deep Blue S7, C236, Browser EV and Aouita E12. More than 10 new products have been planned. Strive to exceed 2.8 million units in production and sales to ensure that the scale growth is more than 10 percentage points higher than the industry. " Wang Xiaofei, vice president of Changan Automobile, said.

　　Building a smart factory

　　Sailisi Liangjiang Smart Factory is the production base of M5 and M7 in AITO. As a leading private automobile enterprise in Chongqing, Cyrus has taken the initiative to change since 2016, started to develop new energy vehicles, and upgraded its products by relying on technological innovation.

　　Walking into the Sailisi Smart Factory in Liangjiang New District of Chongqing, the mechanical arm is telescopic and rotating, more than 1,000 robots cooperate in an orderly manner, and laser welding runs at high speed. Here, it takes only 5 seconds to punch a set of automobile parts.

　　Among them, stamping is the first process of making a car. The stamping workshop here has advanced technologies and equipment such as dust prevention and noise reduction, automatic packing, AGV automatic transmission, one-button die change, etc. It takes only 5 seconds to punch a part in a fully enclosed high-speed synchronous mechanical stamping line. At the same time, the stamping workshop is equipped with the most advanced blue light detection system in the world at present, the detection efficiency is 3 -5 times that of the traditional three-coordinate detection in the automobile factory, and the detection accuracy is 0.05 mm, which is thinner than a hair, which is an accuracy that cannot be achieved by manual operation.

　　In the welding workshop, it is more like a kingdom of robots, with more than 300 robots waving their "arms" constantly. The seemingly rugged and powerful "arm" can actually "embroider". Thanks to the advanced laser remote flying welding technology, flying welding can realize rapid welding by increasing laser energy and adjusting assembly gap without touching parts. "The thinnest part can reach 0.08mm, and its automation rate can reach 100%." The staff of Sailis Smart Factory introduced.

　　The production line of the workshop adopts the adaptive welding controller from Bosch, which can automatically monitor the change of solder joint material and environment, and automatically adjust the whole welding parameters to ensure that each solder joint can meet the quality requirements. It is worth mentioning that this technology is only used in high-end automobile manufacturing at present, but it can be found in the factory of Sailis.

　　A large number of seven-axis spraying robot arms are used in the painting workshop, which is the first automobile production line in China using seven-axis robot arms. Compared with the six-axis manipulator, the seven-axis manipulator is more flexible, which is convenient for the end effector to reach a specific position. Even in the dead corner of the car body, the seven-axis manipulator can paint with ease.

　　It was put into production in 2019, and the factory was built according to the standard of Industry 4.0. It has five process workshops: stamping, welding, painting, final assembly and battery PACK. At the same time, more than 1,000 robots work together to achieve a high degree of automation, and 100% automation is achieved in key processes, and online inspection is carried out 24 hours a day, which not only effectively reduces labor costs, but also makes manufacturing more accurate.

　　In September 2022, Liangjiang New Area signed a strategic cooperation agreement with Sailisi Group. According to the agreement, Celestial Wenjie New Energy Vehicle Upgrade Project will be located in Longxing Intelligent Networked New Energy Vehicle Industrial Park in Liangjiang New District, helping Chongqing to build a world-class intelligent networked new energy vehicle industrial cluster.

　　The Sailisi new energy vehicle upgrade project is another intelligent production base driven by digitalization and intelligence, combined with new technologies such as big data and Internet of Things, and built by using digital twin technology. According to the plan, the project will be completed in the fourth quarter of 2023. After completion, the overall intelligent level will reach the international advanced and domestic leading level, and it will become another benchmark project for intelligent manufacturing of new energy vehicle enterprises in China.

　　Investment continues to increase.

　　As the "main battlefield" of Chongqing’s automobile industry, the automobile industry in Liangjiang New Area accounts for 70% of Chongqing. According to statistics, up to now, there are 64 high-end R&D platforms in Liangjiang New Area, including China Automobile Research Institute, German Mainland and France, with a total investment of 6.5 billion yuan in recent years, which has spawned a large number of new technologies and applications.

　　In terms of intelligent networked vehicles, the district has gathered 6 enterprises producing intelligent networked vehicles and 18 enterprises related to other links in the industrial chain, which are mainly distributed in the fields of chips, millimeter-wave radars, operating systems, intelligent driving systems, unmanned solutions for specific scenes, positioning communication, central controller, intelligent cockpit, computing resources, vehicle-road coordination and intelligent transportation.

　　In addition, Liangjiang New District is building a national-level pilot area for vehicle networking, and has built a 128-kilometer two-way demonstration road of Shiyu Expressway, a nearly 100-kilometer urban demonstration road (including intelligent networking test road), and built pilot demonstration areas such as Jialijia Smart Park and Liangjiang Collaborative Innovation Zone. Up to now, more than 500 sets of RSUs have been installed and more than 250 OBU vehicles have been installed.

　　A single flower does not make a spring. While creating the leading effect of automobiles in Liangjiang New District, all districts and counties are also aiming at Chongqing to accelerate the goal of building a world-class intelligent networked new energy automobile industry cluster with a trillion-dollar level.

　　On February 8th, jiangjin district Municipal People’s Government and Dongfeng Xiaokang Automobile Co., Ltd. formally signed a contract on the intelligent networked new energy vehicle project, with a total investment of 3.2 billion yuan, which was settled in Jiangjin District of Science City (Shuang Fu Industrial Park).

　　In the field of intelligent networked new energy vehicles, Shapingba District has made great efforts to build a new track, with Cyrus as the leader, continuously attracting "left and right generals", speeding up the construction of high-end supporting projects such as Topp and Wencan, strengthening the chain, deepening the development model of "faucet+supporting+platform+key technology+scene", and promoting the deep integration of the industrial chain, value chain and innovation chain "three chains" of intelligent networked new energy vehicles.

　　The continuous overweight of car companies and the continuous efforts of various districts and counties have given Chongqing more confidence in building a world-class intelligent networked new energy automobile industry cluster.

　　"The development of intelligent networked new energy automobile industry is not only the main direction to promote the high-quality development of the automobile industry in the future, but also the key task to improve the mobile travel of the automobile industry and the construction of its social ecosystem." Zhou Qing, deputy secretary-general of Chongqing Municipal Government, said that Chongqing has the ability and responsibility to build a world-class intelligent networked new energy automobile industry cluster.

　　On August 19th, 2022, the Chongqing Municipal Government issued the Development Plan for Building a World-class Intelligent Networked New Energy Automobile Industry Cluster in Chongqing (2022-2030).

　　According to the plan, by 2025, the production and sales of new energy vehicles in Chongqing Intelligent Networking will account for more than 10% of the national total. By 2030, Chongqing will build a world-class intelligent networked new energy automobile industry cluster, and the industrial scale will reach the world-class level; Build one or two world-class intelligent networked new energy automobile enterprises and brands, form a world-class intelligent networked new energy automobile industrial chain ecology, and build a world-class intelligent networked new energy automobile experience capital. The intelligent networked new energy automobile industrial chain, supply chain and innovation chain have strong international radiation capabilities.

　　At present, Chongqing has formulated an action plan for intelligent networked new energy auto parts system, an action plan for innovative application of autonomous driving and car networking, an action plan for application of automotive software and artificial intelligence, and an action plan for infrastructure and services to ensure the implementation and completion of the "planning".
