Seeing General Secretary’s trip to Hebei revealed "the key to Chinese modernization"

  On May 12th, General Secretary of the Supreme Leader came to Shijiazhuang, Hebei Province, went into the production workshop to inspect the chip production process, and went into the exhibition hall to inspect the display of pharmaceutical products. Walking all the way, looking all the way, thinking all the way, guiding all the way, focusing on one theme: promoting the coordinated development of Beijing, Tianjin and Hebei, and grasping one concern: self-reliance and self-improvement of science and technology.

  Self-reliance in science and technology is the "great country" in the mind of the Supreme Leader General Secretary. During an inspection tour in Guangdong last month, the general secretary pointed out that achieving high-level scientific and technological self-reliance is the key to Chinese modernization. This time, it is emphasized that "accelerating the construction of a powerful country through science and technology is the strategic support for building a socialist modern country in an all-round way and promoting the great rejuvenation of the Chinese nation in an all-round way".

  Repeated emphasis and high attention reflect the profound insight into "time" and "potential", a clear understanding of goals and paths, and a firm determination to implement the new development concept.

  "Facing the forefront of world science and technology, facing the main battlefield of economy, facing the major needs of the country, and facing people’s lives and health", we entered the China Institute of Electrical Industry, and the 31 Chinese characters on the exhibition board on the first floor attracted people’s attention.

  These "four orientations" are the clear requirements put forward by the general secretary for scientific and technological innovation. At the symposium of scientists in September 2020, the General Secretary of the Supreme Leader expanded "facing the world’s scientific and technological frontier, facing the main battlefield of economy and facing the major needs of the country" to "facing the world’s scientific and technological frontier, facing the main battlefield of economy, facing the major needs of the country and facing people’s lives and health".

  In the new journey of national rejuvenation and drawing a grand blueprint for future development, the 20th National Congress of the Communist Party of China has made strategic arrangements around "accelerating the implementation of the innovation-driven development strategy", and the first place is to adhere to the "four orientations".

  Chip, known as "modern industrial grain", is not only the frontier technology of the country’s major demand, but also the key core technology that must be overcome. The general secretary pays special attention to this.

  In June last year, General Secretary of the Supreme Leader came to Wuhan University of Technology Laser Engineering Co., Ltd. to carefully examine the display of innovation achievements in the chip industry. "With the development and growth of China, we have broken through ‘ Get stuck in the neck ’ The key core technologies are urgent. We must adhere to the problem orientation, give play to the advantages of the new national system, work hard, catch up, and accelerate the realization of self-reliance and self-reliance in science and technology. "

  When I came to Shijiazhuang this time, I heard the staff of China Electric Power Department introduce product research and development, strengthen the development of integration of defense and civilian technologies, and enhance the capacity building of independent support. The general secretary once again stressed: "We must aim at the national strategic needs, systematically deploy key innovation resources, and give full play to the deep integration advantages of Industry-University-Research, and constantly make new breakthroughs in key core technologies."

  The sense of urgency, problem-oriented methodology and the general direction of "aiming at national strategic needs" run through the general secretary’s strategic plan and ardent expectations for conquering core technologies and realizing scientific and technological self-reliance.

  Look at the development of biomedical industry, which is a strategic emerging industry "oriented to people’s lives and health". From "three drugs and three parties", to COVID-19 vaccine, and then to domestic COVID-19 specific drugs, the innovative development of biomedical industry plays an irreplaceable role in the decisive victory of epidemic prevention and control.

  How to achieve greater development is related to the national economy, people’s livelihood and national security? The general secretary has a long-term plan. "It is necessary to strengthen the capacity building of basic research and scientific and technological innovation, and firmly grasp the lifeline of the development of the biomedical industry in our own hands." "R&D and production of more suitable for China people’s life gene inheritance and physical fitness characteristics ‘ China medicine ’ In particular, it is necessary to strengthen the inheritance, innovation and development of Chinese medicine. "

  Between the lines, it shows foresight and embodies the supremacy of the people.

  Independent innovation is not to build a car behind closed doors, not to fight alone, the key is to form a joint force.

  From "laying a solid foundation" to "building a building", it is inseparable from the deep integration of Industry-University-Research. This is a vertical synergy.

  Take the biomedical industry in this investigation as an example. From basic theoretical research, drug research and development, clinical trials, large-scale production, forming industrial clusters, and promoting the deep integration of innovation chain’s industrial chain, capital chain and talent chain, we can continuously improve the level of transformation and industrialization of scientific and technological achievements.

  Horizontal synergy is also crucial.

  "Beijing-Tianjin-Hebei, as one of the three important power sources leading the country’s high-quality development, has a large number of first-class universities and high-end research talents. It has a solid foundation for innovation and strong strength. It is necessary to strengthen collaborative innovation and industrial cooperation and play a leading role in achieving high-level scientific and technological self-reliance." When presiding over the symposium to further promote the coordinated development of Beijing-Tianjin-Hebei, the general secretary’s words hit the nail on the head.

  In January 2019, the General Secretary of the Supreme Leader inspected and presided over the symposium on the coordinated development of Beijing-Tianjin-Hebei in three provinces and cities, and "collaborative innovation" was also one of the themes. "It is necessary to gather and utilize high-end innovation resources, actively carry out research and development cooperation on major scientific and technological projects, and build an important source of independent innovation and a major source of original innovation in China."

  Work hard on "cooperation" and use pen and ink on "integration" to realize complementary advantages and strong alliance. In the major national strategy of promoting the coordinated development of Beijing-Tianjin-Hebei, synergy, innovation, vitality and strong motivation will be enhanced.

  Such a report card is particularly eye-catching. The Beijing-Tianjin-Hebei National Technology Innovation Center was accelerated, and 11 technological achievements reached the world advanced level; There are 1,117 "little giant" enterprises specializing in Beijing, Tianjin and Hebei, and more than 9,000 provincial-level specialized and innovative small and medium-sized enterprises have been cultivated; Located in Baodi, Tianjin, Beijing-Tianjin Zhongguancun Science and Technology City is accelerating to become a "collaborative highland" … …

  The combination of "overall situation" and "one domain", and the unity of "long-term" and "present" plan a big chess game of self-reliance and self-improvement of high-level science and technology. Grasp the general trend, make a good "first move", and make full use of it all at once.

Russia has publicly declared that it will accelerate the modernization of nuclear forces.

  Xinhua News:General Vladimir Popov King, Deputy Minister in charge of weapons and equipment of the Russian Ministry of Defense, publicly stated at a press conference on the 5th that the Russian defense procurement funds will not be cut in 2009 -2011, and a quarter of the funds will be used for the modernization and upgrading of strategic nuclear forces. The website of the Russian "Viewpoint" broadcasted a signed article entitled "Expecting missiles" on the 5 th. The main points are as follows:



General Vladimir Popov Kim, Deputy Minister in charge of weapons and equipment of the Russian Ministry of Defense.


  When talking about the drafting of the national equipment plan for 2011 -2020, popovkin said that the future plan aims to eliminate the imbalance between military maintenance expenses and equipment expenses in the military expenditure structure. By 2011, the proportion of the two will reach the same level, that is, 50% each. By 2015, the ratio of the two will become 30% to 70%, that is to say, 70% of military expenditure will be used to buy new sophisticated weapons.


  Popovkin said that the amount of defense procurement in 2009 -2011 will reach 1.5 trillion rubles (about 42 billion US dollars) and will not be cut. This seems to be a huge number, but the amount set last year has been greatly reduced by inflation (the inflation rate in 2008 was 10%-11%). Inflation is still rising, and according to the most conservative estimate, it will reach 15% by the end of this year. Considering this factor, it is hard to think that the allocation for arms procurement for three years has not been cut.


  Fortunately, a real large sum of money will finally be invested in the military sector. Now, it is crucial to ensure that the money can reach the "end users"-weapons and equipment producers. China has always had many problems in this respect, although it has been trying to reverse this unfavorable situation.


  Although popovkin vowed that 15% of defense orders in 2009 had been paid in advance to military enterprises, according to the information held by this newspaper, some military enterprises have not received the payment delivered in the third quarter of 2008.


  According to popovkin, the Air Force will buy 50 new fighters in 2009. This figure is not questioned, and it is easy to allocate by model. The 24 MIG -29CM T returned by Algeria will account for half of the order. There are also eight Su -27CM fighters, which are new fighters upgraded according to the 2007 contract. 6-8 upgraded Su -25CH fighter planes and 10-12 upgraded Su -24M 2 frontline bombers. Only two Su -3 4 bombers are completely new and are scheduled to be delivered this year.



Russian "Baiyang" intercontinental missile


  General popovkin focused on the development of strategic rocket soldiers and strategic nuclear forces at sea, and a quarter of the defense procurement expenses will be used for the modernization and upgrading of these two items. He first promised that the "Brava -M" submarine-launched missile, which failed repeatedly this year, would be installed, so more test firing was needed.


  Much more important than the "Brava" issue is the report that more than 10 intercontinental ballistic missile launchers will be added to the strategic rocket force this year.


  In his speech, the equipment director mentioned that it was no accident that Russia developed a space defense weapon system. He explicitly warned: "No matter which country wants to deploy weapons in space, Russia will oppose it." Although both the United States and China have successfully tested anti-satellite weapons, there is no doubt that China is still the only country with excellent anti-satellite weapons that can be manufactured within a reasonable period of time. The unique A-36 anti-missile system in the world is an example. (Editor: Apeng)

People’s Daily: Domestic machine tools, high-end breakthrough-State-owned Assets Supervision and Administration Commission of the State Council

"In 2020, the operation of the machine tool industry was better than expected, showing a recovery growth trend." A few days ago, Mao Yufeng, executive vice chairman of cmtba, said that after nearly 10 years of downturn, the machine tool industry is welcoming new opportunities for development.

Machine tool, the machine that produces machines, is called "industrial mother machine" and is the core production base of equipment manufacturing industry. In the extraordinary year of 2020, the machine tool industry intensively cultivated and made many new breakthroughs in the field of high-end CNC machine tools: a major breakthrough was made in the super-large five-axis machine tool, and the world’s first 3D printing CNC machine tool with integrated casting, forging and milling was successfully developed …

During the "14th Five-Year Plan" period, how did the machine tool industry make up the short board and forge the long board?

Mid-to-high-end blossomed, and the machine tool industry showed signs of bottoming out.

In the spring of 2020, the machine tool industry reported good news frequently.

The first domestic high-speed five-axis machining center for ultra-long-distance high-speed rail developed by Shenyang Machine Tool of General Technology Group was successfully rolled off the assembly line. This machine tool is used for machining complex surfaces of large-scale structural parts of high-speed rail, marking the first time that domestic high-end CNC equipment is used for the production of core components in high-speed rail industry.

A month ago, the testing method of five-axis machine tool of "S specimen" revised by China officially became an international standard, and the machine tool people frankly said, "This is a hard bone."

"S specimen" is regarded as the "crown jewel" in the field of machine tool processing. As long as a machine tool can process qualified "S-specimen", then even complex thin-walled parts can be competent. The machining of "S-specimen" requires the machine tool to change various angles and ensure high machining accuracy.

"The core components of our machine tool have withstood the test of’ S specimen’." The person in charge of a leading machine tool enterprise in China said that it was a lot of suffering to break through the "S-specimen". "During the test, all the inspection points of machine tool processing were qualified, but the combined" S-specimen "always failed to meet the standard."

The reason is that there is still a gap in machining accuracy. Each inspection point should not only meet the standard, but also have almost zero error, so as to ensure that the error of the outline size of the "S specimen" does not exceed 0.05 mm. The R&D team of this enterprise keeps approaching zero error. After more than 1,200 tests, it finally chews this "hard bone" and realizes 100% qualified processing of "S specimen".

Mao Yufeng said that the localization of high-end machine tools in China is constantly improving. Up to now, the domestic market share of representative products such as domestic five-axis machining center and high-grade CNC system has increased to about 30%.

What is more gratifying is that not only the leading enterprises of large machine tools continue to conquer key technologies, but also the "invisible champion" in the segmentation field is breaking. In November 2020, nearly 20 enterprises in the machine tool industry were selected into the second batch of "Little Giant" enterprises publicized by the Ministry of Industry and Information Technology.

On January 4th, 2021, Shenzhen Genesis Machinery Co., Ltd. delivered another good news, and 218 T-V856s machine tools were shipped in a single day, setting a new high in recent years and winning a "good start". With reliable processing quality, the company has jumped to the forefront of subdivision in just over 10 years.

"In the past 10 years, the demand of China’s machine tool market has changed dramatically, from completely relying on investment to investment and consumption." Mao Yufeng said that in the past, the customers of machine tool enterprises were mainly concentrated in heavy industries such as energy, steel and equipment manufacturing. Now, customers have expanded into electronic products, new energy vehicles, medical devices and semiconductors. "Some enterprises that are not suitable for market demand have been eliminated, and a number of enterprises that respond quickly and focus on sub-sectors have grown rapidly."

Breakthroughs have been made at the high end and progress has been made at the middle end. The machine tool industry is gradually getting rid of the downward trend for many years, showing signs of bottoming out. According to the data of cmtba, in 2020, the total orders of metal processing machine tools increased by 16%.

Strengthen collaborative innovation and realize the expansion from 1 to 100 and from point to surface.

As an "industrial machine tool", the application scenes of machine tools are everywhere, ranging from small mobile phones, televisions and washing machines to large cars, high-speed trains, airplanes and rockets, and as fine as medical implants and medical devices, they are inseparable from machine tools. China’s economy is developing towards high quality, and the requirements for product quality and machine tools are getting higher and higher. "It can be said that the supply capacity and demand of domestic high-end machine tools do not match, not only the whole machine has a gap with imported machine tools, but also the key basic supporting parts." Mao Yufeng said.

Where is the gap? It lies in sustainable innovation based on application.

Zhu Kongfeng, deputy chief engineer of guangzhou cnc Equipment Co., Ltd. said that China has been able to produce high-end CNC system for machine tools, taking CNC system as an example, and achieved a breakthrough from 0 to 1. However, compared with imported high-end CNC systems, there is still a gap in technology maturity and brand influence. "It is these gaps that make it difficult for domestic CNC systems to expand from 1 to 100, from point to surface. At the same time, without the tempering of high-end application scenarios, the gap between domestic high-end CNC systems and foreign products will be difficult to make up, and even larger. "

"Good products are used. If no one uses them, there is no way to know the gap. There is no application scenario. How to upgrade the iteration?" Jiang Shilin, assistant to the chairman of Dalian Guangyang Science and Technology Group, felt that the high-end machine tool market is small in scale and high in unit price, and the price factor has little influence. "It is very difficult to develop domestic high-end CNC machine tools only by relying on enterprises themselves and market forces."

Mao Yufeng said frankly that for a long time, the prototype research and light application verification in the machine tool industry often means the completion of the project through the acceptance of the prototype. Few people pay attention to the follow-up application and market expansion of the products, and lack policy support for the promotion of innovative products of enterprises. This innovative model can only solve the problem of "being or not" and cannot meet the needs of high-quality development.

Faced with this dilemma, some enterprises have made useful explorations.

"We have advanced the time to find customers." Jiang Shilin said that in the past, products were sold to customers and they were asked to try them out. Now we come to the door first and ask our customers what their needs are, and the two sides research and develop together. "We understand the psychology that customers favor imported mature machine tools. After all, every failure and shutdown of the production line will cause huge losses. Therefore, we can only do our homework first. "

Recalling the first cooperation with a research institution, Jiang Shilin will never forget the more than 200 pages of A4 paper filled with questions. "The first joint research and development, customers asked us to use the standards for inspecting imported advanced equipment. For us, the problem paper with a thickness of 3 cm is not harsh, it is a baby. " Jiang Shilin recalled that after improving the equipment, the company sent engineers directly to the customer’s workshop to solve problems at any time, so as to improve the reliability of the equipment, the adaptability of the process and the stability of production, so as not to affect the performance of the operators and improve their enthusiasm for operating domestic equipment. After a joint research and development, Dalian Guangyang finally won the recognition of customers. The customer purchased 22 high-end five-axis machine tools at one time to form an intelligent production line. "After that, the company’s products opened up a situation in the aerospace field."

"The supply mode of the machine tool industry is changing from batch to customization, especially for mid-to high-end products. It is even more necessary for the machine tool industry to strengthen collaborative innovation practice with users, from passively following to solving user needs to jointly researching new needs and new processes." Mao Yufeng said.

Industry-University-Research actively embraced new technology with a game of chess.

Sharp tools make good work. For the manufacturing industry, this "device" is a machine tool. During the "Fourteenth Five-Year Plan" period, the machine tool industry has a long way to go to make up the short board and forge the long board.

"From the perspective of products, a good machine tool needs the quick march of the whole industry chain. The basic components determine the functional components, and the functional components determine the performance of the main engine. This is an interlocking process." Zhu Kongfeng said.

From the industry point of view, machine tools and a series of basic industries such as semiconductors, raw materials and cutting tools are interdependent and interdependent. For example, a high-end machine tool needs high-quality bearings, and high-quality bearings depend not only on the quality of steel, but also on the performance of the machine tool used to process bearings.

"This means that the machine tool industry needs to make up the shortcomings. It is not feasible to rely solely on the head enterprises, but it needs the user’s demand to lead and Industry-University-Research to use a game of chess." Jiang Shilin said.

Mao Yufeng emphasized that it is foreseeable that the demand for domestic high-end machine tools is expected to explode further during the 14 th Five-Year Plan period. In terms of major demand and common technology research and development, we need to explore how the new national system can play a better role.

Zhu Kongfeng said that, just as the "Proposal" of the Tenth Five-Year Plan proposed to implement the system of "revealing the list and taking the lead", he hoped that the relevant departments would guide the downstream enterprises to publicly release their needs and jointly research and develop with the upstream and downstream of basic industries and machine tool industry chains to form a new development pattern of complementarity, collaborative research and mutual promotion. "Government departments can adopt the way of purchasing services, with leading enterprises contracting related projects and organizing project participants by themselves to realize key core technologies.

"Although the machine tool industry accounts for less than 1% of GDP, it is the basis for upgrading the manufacturing industry to the middle and high end. To achieve high-quality development, the industry needs the strong support of more capital. " Mao Yufeng suggested that state-level large funds invest more in the machine tool industry, and at the same time give more opportunities to private enterprises. "After nearly 10 years of development in the machine tool industry, private enterprises have become an important force that cannot be ignored."

However, bury your head in the road and look up at the road. In recent years, subversive innovations in the machine tool industry have come out one after another, which not only makes up for the shortcomings of traditional CNC machine tools, but also affects the research and development ideas of traditional machine tools.

According to reports, the traditional CNC machine tools "do subtraction" in processing, and process mechanical parts by turning, milling, planing and grinding, which has the advantage of high reliability. 3D printing technology is "addition". First, liquid materials are solidified into planar thin layers, and then layers of thin layers are accumulated into the required three-dimensional objects, which is superior to controlling complex shapes. A few days ago, in Wuhan, a brand-new machine tool-casting-forging-milling integrated 3D printing CNC machine tool combined the advantages of the two.

"Many precision parts needed by modern industry have complex structures and extremely high requirements for precision and air tightness. Machining with traditional CNC machine tools is extremely difficult to control accuracy, while 3D printing technology has shortcomings in terms of air tightness. " Zhang Haiou, the project leader and a professor at Huazhong University of Science and Technology, said that the 3D printing CNC machine tool integrating casting, forging and milling combined their advantages into one, forging while casting, and successfully trial-produced the aircraft composite molding die only once, which not only met the requirements in parameters, but also overcame the bottleneck problems of difficult processing and low yield of complex large molds, and shortened the manufacturing cycle by at least 1/3.

"In order to meet the needs of efficient and flexible manufacturing, the transformation of traditional machine tools is imperative, which requires the machine tool industry to actively embrace new technologies and be ready to meet new challenges while practicing internal strength." Mao Yufeng said.

  On the day of the competition, Tanskuzina and Polish player Natalya Sadovska competed for the award of the best chess player in the world. During the competition, the organizer’s staff suddenly took away the Russian flag on the table and tore off the Russian tricolor flag label on the table.

  The staff’s move surprised Russian contestants. Tamara looked around in surprise, then at the table, where the Russian flag was placed a few seconds ago. But Tamara soon calmed down and continued to concentrate on the game.

  The organizer later explained that during the competition, the staff were reminded that court of arbitration for sports had previously stipulated that Russia was forbidden to use the Russian flag and national anthem in large-scale international competitions. In view of the fact that the game has already started, the staff of the World International Checkers Federation had to directly withdraw the items related to the Russian national symbol from the table. In addition, the staff explained that this was done because they might be sanctioned for this matter. In the end, the Russian player Tanskuzhina was defeated.

  On December 17, 2020, court of arbitration for sports found that the Russian Anti-Doping Center violated the rules, and announced that Russian athletes could not represent their country in major international sports events including the Tokyo Olympic Games and the world championships of various events until December 16, 2022, but only participated in a neutral capacity, and were not allowed to use the Russian flag and national anthem.

Musk’s chaotic private life was exposed: his son was accused of "like father, like son"

On June 23rd, Beijing time, it was reported that the son of Tesla CEO Elon Musk was not only transsexual, but also broke off relations with his father, which sounded strange. However, there is an old saying in China that "like father, like son". Perhaps you are not surprised to see Musk’s chaotic private life.

Musk’s repeated divorce is obviously unfavorable to the child’s growth, which may affect the child’s personality.

Musk currently has seven children and has been divorced three times, including one divorce, remarriage and then divorce. He and Canadian singer Grimes are now in a "semi-separated" state, and they are raising two children together. However, Musk was unwilling to be lonely and fell in love with a Hollywood actress.

Let’s take a look at Musk’s chaotic private life:

In 1971, Musk was born in Pretoria, South Africa. There are three children in the family. He is the eldest son. His mother, Maye Musk, is a Canadian model who once appeared on the cover of Time magazine. At the age of 69, she became the spokesperson for the cover girl of a famous American makeup brand. His father, Errol Musk, is an engineer.

Musk once told Rolling Stone that he had struggled with loneliness since he was a child. "When I was a child, I said one thing," Musk said, "‘ I never want to be alone. ’”

On the whole, Musk’s childhood life was not satisfactory. He was bullied mercilessly at school, and even was hospitalized because the abuser pushed him down the stairs. In about 1979, shortly after his parents divorced, Musk went to live with his father errol. Musk said that their relationship has now alienated.

Musk’s relationship with his younger brother Kimbal and his younger sister Tosca still seems to be very close. All of Musk’s brothers and sisters seem to have entrepreneurial characteristics: Kimbarl tries to make the food industry more sustainable and healthier, while Tosca has launched Passionflix, a love movie network.

The relationship between Musk and his mother also seems to be very good. It is reported that he gave Meyer a green Tesla. Meyer moved to California in 2013 to be closer to her children and grandchildren.

He met his first wife, Justine Wilson, at Queens University in Ontario, Canada. Wilson once recalled in the women’s magazine "Jia Ren" that Musk invited her out to eat ice cream. Although she decided to stay at home and study, Musk appeared. "There are two chocolate bean ice cream cones in his hand, and ice cream is dripping on his hand."

Then Musk went to wharton school to study, but he kept sending roses to Wilson.

Later, they went their separate ways, but when Musk started his first company and Wilson started writing her first novel after graduation, they got in touch again. Wilson said that Musk pursued her and gave her a credit card to buy as many books as she wanted. They got married in 2000.

They moved to Los Angeles and gave birth to a son named Nevada, but unfortunately died of sudden infant death syndrome. They finally gave birth to twins and triplets, a total of five children. In 2010, Musk called his children "the love of my life".

The two divorced in 2008. After the divorce, the tech tycoon started dating the actress Talulah Riley.

Although Musk and his first wife gradually drifted apart, Justin wrote in Jiaren magazine that she and Riley finally got along well. She even emailed her ex-husband’s girlfriend and said, "I’d rather live the French film version." The two women became friends and thought about various philosophies. "

Riley and Musk got married in 2010. Two years later, the news of their divorce was made public. At that time, Musk said to Riley on Twitter: "This is an amazing four years. I will love you forever. One day you will make others very happy. "

The two remarried in 2013. Musk applied for a second divorce in the second year, and then withdrew.

In 2016, Riley applied for divorce from Musk and decided to divorce at the end of that year. However, the relationship between the two is still very good, and Riley even appeared in an exclusive interview with Musk in Rolling Stone magazine. "We still meet often and take care of each other." She said.

In 2016, Musk started dating actress Amber Heard, but broke up a year later because of the tight schedule.

Musk commented on an Instagram post by Hilde that he and his predecessor "are still friends, close and in love with each other," adding, "Who knows what will happen in the future." He later told Rolling Stone magazine: "I really love her, which hurts me."

In May 2018, Musk and Canadian musician Grimes attended the annual Fashion Institute Celebration held at the Metropolitan Museum of Art.. At that time, Page Six reported that the two had been "quietly dating" for several weeks.

Musk's chaotic private life was exposed: his son was accused of "like father, like son"

Grimes and Musk met through Twitter. Musk had intended to make a joke about artificial intelligence, especially about her role as Rococo basilisk in the music video of "Bloody Meat", but found that she had already taken the lead.

Musk later told The Wall Street Journal that he liked Grimes’s "wild artistic creativity and serious work ethic".

In September 2018, Musk smoked marijuana while participating in the live webcast of American comedian Joe Rogan, which caused controversy. Musk seems to have a soft spot for marijuana culture. He said in 2018 that he was going to privatize Tesla for $420 per share. The number 420 is widely regarded as the code name for smoking marijuana. In April 2022, Musk proposed to acquire Twitter for $54.20 per share, which also included 420.

In January 2020, Grimes posted a photo on her Instagram and Twitter accounts that appeared to be pregnant. Later, she confirmed that she was pregnant with Musk’s child.

On May 4th, 2020, Musk announced the birth of their son. He and Grimes named him "XA-XII Musk", which seems to be pronounced "X Ash A-12". "Mother and child are safe." Musk wrote on Twitter.

In December of the same year, Musk said that he moved to Texas after several months of struggle with California’s epidemic prevention and control measures. Grimes and his baby X seem to have moved together. In March of that year, he shared a family photo taken near SpaceX facilities in southern Texas.

But in September 2021, Musk told Page Six that he and Grimes had broken up. Musk explained at the time: "Mainly because my work at SpaceX and Tesla requires me to stay in Texas or travel overseas most of the time, and her work is mainly in Los Angeles."

In March 2022, Grimes revealed in an interview with Vanity Fair that they secretly gave birth to a girl named Ayxa SiderlMusk through surrogacy.

Grimes explained that "Exa" refers to the supercomputer term "Exaflops", "Dark" stands for unknown factors, and "Sider?l" is the elvish spelling of stars, which means "the real time of the universe". Grimes and Musk called her Y for short.

Grimes told Vanity Fair that she and Musk are not getting back together, and their relationship is "very unstable", but they plan to have more children.

However, Musk seems to have a new love.In February of this year, Musk was photographed getting out of his private jet with Australian actress Natasha Bassett. It is said that the two have been secretly dating for several months.

In April this year, Musk’s 18-year-old transgender son applied for a legal name change to confirm his "female" gender identity and sever relations with Musk. In her application, she wrote that she no longer lives with her biological father and does not want to "have any relationship with her biological father".

Limited time sale of 159,900 Passat 380TSI family listed.

speed up apply the brakes oil consumption second rice rise Car sales are responsible! Test the new Passat 330TSI Evaluation Editor-Sheng Yuanjun:

The power performance of Passat 330TSI(1.8T) model is very decent, and the throttle response is not as sensitive as that of 2.0T model. Although it may not feel strong enough, the power is not weak in essence. For those friends who have a calm driving style, 1.8T is even more pleasing than 2.0T. In addition, the DCC chassis function provided by the car is a bright spot, which obviously improves the pleasure of driving. In short, if you want to buy a Passat representative, a model with balanced performance in all aspects and moderate price, the 1.8T model is definitely the first choice.

Evaluation Editor-Qi Zixin:

As Passat’s best-selling displacement, the 1.8T model is a balanced one. The performance of the new generation EA888 engine has been improved, which will help improve Passat’s competitiveness. Large space, adequate configuration, good performance and stable appearance all meet the needs of consumers in China. In my eyes, he doesn’t have any outstanding highlights, but he also has no shortcomings. He has achieved a sales volume of 200,000 vehicles a year and will have excellent market performance compared with the new models. For those who want to buy a medium-sized car that can take care of both home and business, buying a Passat is an infallible choice.

Evaluation Editor-Huang Zhengqiao:

The well-known name Passat has given SAIC Volkswagen too much confidence, so they are not going to change into the latest MQB platform, but still adjust the appearance of the existing models and sell them for a few years. In all fairness, the driving quality of Passat equipped with the third-generation EA888 1.8TSI engine is not outstanding. The gearbox at low and medium speeds has a certain setback, and the power output is not as smooth as that of 2.0t. If the budget is sufficient, I would still recommend you to choose the 2.0TSI model.

    China Journal Global Online News: Leaders of EU member states signed the Lisbon Treaty in Lisbon, Portugal, on the 13th. If the treaty is finally ratified by member States, it will pave the way for the reform of EU institutions.


    The signing ceremony was held in Jeronimos Monastery, which was listed as a world cultural heritage by UNESCO. Portuguese Prime Minister Socrates, the rotating presidency of the European Union, European Commission President Barroso and European Parliament Speaker Petrin delivered short speeches successively.


    Socrates said that the Lisbon Treaty will make the EU more modern, more efficient and more democratic, and will also make the EU’s voice in the world louder. Barroso said that the Lisbon Treaty will make the EU better serve the citizens of its member countries and make the EU’s foreign policy more coherent. The signing of the Lisbon Treaty has made the EU full of confidence in the future.


    After the speech, the leaders of the 27 member States of the European Union signed the treaty one after another. The signing of the Lisbon Treaty marks the temporary end of the constitutional crisis that has plagued the EU for more than two years. According to the plan, the treaty ratification procedure will be completed in 2008 and will take effect before the European Parliament election in 2009.


    In 2005, after the EU Constitutional Treaty was rejected by France and the Netherlands, the EU was caught in a constitutional crisis, and the issue of institutional reform was forced to be shelved. In March this year, EU leaders adopted the Berlin Declaration, announcing the end of the constitutional reflection period. The Lisbon Treaty, regarded as a simplified version of the EU Constitutional Treaty, was born six months later.


    According to the Lisbon Treaty, the Council of the European Union will have a permanent president to replace the current rotation mechanism of the EU presidency once every six months; At present, the two overlapping functions of the EU High Representative for Foreign Affairs and Security Policy and the European Commission Commissioner for Foreign Affairs will be merged; The European Commission will be slimmed down, and the current practice of appointing an EU member in each member state will be abolished; Replace the current "effective majority voting system" with "double majority voting system"
