"What is the use of a three-fold mobile phone?"

After the release of Huawei Mate XT, the questions and answers in Little Red Book swarmed together. The only certainty is: it is definitely useful, what’s the use, and then.

At the beginning, I was planted with grass by this video.

At the press conference on the afternoon of September 10th, Mate XT, the world’s first mass-produced three-fold mobile phone, finally officially appeared. Judging from the hot pre-sale and the highest speculation price of 70,000 yuan in the second-hand market, "whether the market accepts" and "whether the demand is real" no longer need self-proof-the remaining question is simple and direct: Is it worth paying 20,000 yuan or more for this new type of mobile phone as an early adopter of technology?

Some folds are cute. Giphy

Some folds are delicious. Giphy

Look at the configuration and price section first:

Mate XT has three versions: 16 GB+256 GB, 16 GB+512 GB and 16 GB+1 TB. The prices are 19,999 yuan, 21,999 yuan and 23,999 yuan respectively; The color is divided into black and red, which supports Tiantong satellite communication.

Some folding is very expensive … Huawei

Such a big screen in case you get a picture of your face …

The reason why the prefix "mass production" should be added is because before Huawei, there were already three-fold "concept machines" including Samsung, TCL and even the "king of African mobile phones". Some manufacturers even release two or four different forms of "three-fold" concept machines every year to maintain the sense of industry existence …

But by the end of 2024, all these are still at the stage of "concept"; And the real mass-produced three-fold mobile phone, the world is still only Mate XT. Therefore, at the press conference, Yu Chengdong once again shouted "Huawei depends on the folding screen", a classic slogan when Mate X, Huawei’s first-generation folding screen mobile phone, was released.

Yes, the other three folds you remember can’t be mass-produced … Huawei?

The mobile phone that can be folded into three stacks has a screen size of 10.2 inches in the unfolded state, which is equivalent to the traditional tablet computer, and is known as "the largest folding screen mobile phone in the world"; In the unfolded form, the thickness is only 3.6 mm, and it is also known as "the thinnest folding screen mobile phone in the world".

Because the current mainstream scheme of triple folding is zigzag folding, in fact, both "inward folding" and "outward folding" hinge designs are involved in a mobile phone. Huawei Mate XT uses a hinge system called "Tiangong" to realize internal and external folding for the first time. In fact, Huawei has gone through a "detour" in two kinds of hinge structure technologies in its early years, and now it has become a rare technical reserve.

The unavoidable topic of hinge technology: Huawei

How can folding screens evolve?

The complexity (and charm) of folding screen lies in that with the increase of screen and folding number, the strength, endurance, system application and creativity of multi-screen switching combination of mobile phone (body+screen) must be matched.

The huge screen brings more extreme requirements for screen strength. One of the biggest problems in the traditional double-folding mobile phone so far is the lack of screen strength. This time, Huawei used an ultramicro-folded organic material and a composite super-tough laminated structure composed of non-Newtonian fluid material and UTG glass, claiming to improve the impact resistance of Mate XT screen by 30%.

The bigger the screen, the greater the responsibility.

Battery life is another problem. Mate XT has a 5600mAh silicon-carbon negative battery in the fuselage, and a three-cell parallel design is customized according to the three fuselage spaces, which supports 66W wired super fast charging and 50W wireless fast charging.

As a response to the most popular concept of AI mobile phone, Huawei Mate XT mainly demonstrated a number of AI picture functions this time: for example, the album supports AI elimination, AI expansion and AI cloud enhancement, etc.-not fancy but still practical.

Before the release, what was most imagined in the three-fold application scenario was "the appearance of the mobile phone, the soul of the computer", so a "easy-to-use physical keyboard" replaced "a good-looking mobile phone case" and became the first accessory that the three-fold mobile phone needed first.

The computer in the pocket is really Huawei.

Released with the mobile phone, there is a bracket protective case that allows Huawei Mate XT to rotate at 270 degrees and multiple angles; More interestingly, it is a special folding touch keyboard accessory, which can be easily carried along with Mate XT, giving it a chance to truly become a "computer in a pocket".

The physical object of this bracket protective shell is also very cool.

From the information of the conference, the biggest worry and challenge is the future production quality control and after-sales. The "three-fold" form has indeed raised the mobile phone technology to an unprecedented complexity, and the "test of time" is indeed more demanding for this form.

You must imagine what the "next generation mobile phone" looks like!

However, from the perspective of the concept of mobile phone, none of the above is the core that the three-fold mobile phone really deserves such high attention.

Behind the three-fold hardware and expensive price, smartphone manufacturers are exploring the new form of mobile phones exhaustively-folding screen and AI, which may be the answer, or not all.

Once the imagination of folding screen was just like this, Giphy

Huawei had a good time in the first half of 2024. According to IDC data, Huawei has regained the first place in the mobile phone market in China, and its mobile phone shipments have doubled, which has become the main driving force for Huawei’s overall performance growth. According to the consulting data of public research institutions, Huawei’s share in the folding screen market in the first half of the year was as high as 42%, and the high-end market with a price of more than 10,000 yuan accounted for 67%.

In other words, in China, at least one of every two flagship folding screen phones will be Huawei.

Before the "optimal answer" appears, only by more extreme attempts and explorations can mobile phone manufacturers take the lead in the next era (just like the alternation from physical keys to touch screens)-this is the product philosophy of the top mobile phone manufacturers in the industry at present, who are betting on three-fold mobile phones one after another.

In this Huawei conference, in addition to the attribute of "three folds", the concept of "super terminal" was also mentioned many times: with the gradual improvement of HarmonyOS’s system ecology, the native HarmonyOS App ecology has completely covered the top 5,000 mobile phone applications, and it is no longer compatible with Android App. A larger screen and a "HarmonyOS device" with brand-new interactive logic are indeed capable of becoming the smart portal of the next era.

"Three" is by no means the end of folding numbers.

Even though Tri-Folding is a "masterpiece" of Huawei’s folding screen mobile phone technology at this stage, it does not mean that it will be the end of the evolution of smart phones.

The number three will not be the ultimate in the form of folding screen mobile phones.

　　CCTV News(Focus Interview): On July 4, the Supreme Leader of the President of China attended the 23rd meeting of the Council of Heads of State of the Shanghai Cooperation Organization (SCO) by video in Beijing and delivered an important speech. This is an important multilateral diplomatic action taken by China towards the Asia-Europe region this year. Facing the question of "unity or division, peace or conflict, cooperation or confrontation", the Supreme Leader gave a clear and powerful answer, drawing a blueprint for the development and expansion of the SCO, pointing out the direction for building a community with a shared future for the SCO, and injecting more certainty and positive energy into the maintenance of world peace and development.

　　On the afternoon of July 4, the President of the Supreme Leader attended the 23rd meeting of the Council of Heads of State of the SCO Member States by video in Beijing and delivered an important speech entitled "Keeping in mind the original mission, adhering to unity and cooperation, and achieving greater development". The speech stressed the need to shoulder the heavy responsibility entrusted by the times, keep in mind the original mission, adhere to unity and cooperation, put forward five suggestions on the future development of the SCO, and announced a series of practical measures to build consensus for the development of the SCO, inject more certainty and stability into regional peace, development and prosperity, and inject new strong impetus into the building of a closer SCO community with a shared future.

　　Deng Hao, secretary-general of the Shanghai Cooperation Organization Research Center of China: "The speech of the Supreme Leader pointed out the future development direction of the SCO, and will have important guiding significance for the next development of the SCO."

　　Su Xiaohui, an associate researcher at the China Institute of International Studies, said: "The pattern is a key word. When the president of the Supreme Leader gave the keynote speech, he was not talking about China’s self-interest, but about the development of the world in China’s eyes, and the overall situation of common development of mankind. The core message is that we believe that peace, development, cooperation and win-win are still the trend of the times, and this trend is irreversible."

　　Since its establishment in 2001, the SCO has started from addressing the most urgent security issues of its member states, focusing on combating the "three evil forces", and gradually expanded to a two-wheel drive of security and economy. In the decade since the Supreme Leader proposed to build a community with a shared future for mankind, the SCO has been at the forefront of the times, adhering to the concept of a community with a shared future for mankind, promoting the "Shanghai Spirit" of mutual trust, mutual benefit, equality, consultation, respect for diverse civilizations, and seeking common development, building the SCO Community with a shared future. It has achieved fruitful results in various fields such as security, economy, development, humanities, and health.

　　Su Xiaohui: "The issues of concern of the SCO are constantly expanding, including the process of three-dimensional cooperation and paying attention to more comprehensive issues, which itself reflects the growth and continuous strength of the organization. It can pay attention to more issues, play more roles, and further enhance its influence."

　　The agenda is expanding, the "Moments" of the SCO are also expanding, and the international influence is significantly increasing. The summit officially accepted Iran as a member state of the SCO, and approved the signing of the memorandum of obligations for Belarus to join the SCO. Since then, the number of SCO member states has increased to nine. With observer states and dialogue partners, the SCO covers more than 20 countries and has become the most populous and extensive comprehensive regional cooperation organization in the world.

　　Deng Hao: "Why is the SCO’s membership expansion showing a trend of rapid development? I think the most crucial point is that the advanced nature, foresight, correctness and universality of the’Shanghai Spirit ‘under the current situation have been demonstrated, so more and more countries have realized that the’Shanghai Spirit’ provides them with a new path, new choice and new hope to solve the current global dilemma and get out of the current development dilemma."

　　Ding Xiaoxing, director of the Eurasia Institute of the China Institute of Contemporary International Relations: "The first characteristic is equality, everyone has one vote, everyone has veto power, and everything follows the principle of consensus, which is completely different from some organizations being manipulated by some major powers; the second characteristic is to adhere to the principle of non-alignment and not targeting other regions and organizations. It is also different from some organizations left over from the Cold War, which is to find opponents and enemies. The third characteristic is that the Shanghai Cooperation Organization promotes development through cooperation and seeks security through cooperation, so more and more countries hope to establish ties with the Shanghai Cooperation Organization."

　　From focusing on a single agenda to building a community with a shared future, from six member states to covering more than 20 countries, the SCO’s influence continues to expand. In this speech, the Chairperson of the Supreme Leader summed up the SCO’s development experience from five aspects, namely "adhering to the fine tradition of watching each other and helping each other in the same boat" "practicing the concept of common, comprehensive, cooperative and sustainable security" "upholding the development concept of innovation, coordination, green, openness and sharing" "inheriting the spirit of good-neighborliness and friendship" "safeguarding international fairness and justice, and opposing hegemonic and hegemonic acts".

　　Su Xiaohui: "Under the background of emphasizing the common destiny, the SCO has achieved important results in terms of cooperation on security, development, humanities and other related issues, as well as coordination among countries to bridge differences, proving that promoting the construction of a community with a shared future for mankind is the fundamental way to solve problems and the general trend of human development."

　　Deng Hao: "These five articles have a positive reference role not only for the SCO, but also for the construction of a global community with a shared future for mankind."

　　然而，当今世界变乱交织，百年变局加速演进，人类社会面临前所未有的挑战。团结还是分裂？和平还是冲突？合作还是对抗？再次成为了时代课题。

　　越是在动荡不安的形势下，越要有对历史发展大势的清晰判断。面对时代之问，最高领袖主席坚定作答，“各国人民对美好生活的向往就是我们的追求，和平、发展、合作、共赢的时代潮流不可阻挡”。

　　上合组织日益发展壮大的同时，既有难得的发展机遇，也面临前所未有的风险挑战，下一步该如何去做？最高领袖主席也给出了答案，“我们要肩负起时代赋予的重任，牢记初心使命，坚持团结协作，为维护世界和平与发展注入更多确定性和正能量”。

　　丁晓星：“挑战主要集中在三方面，上海合作组织成员国越来越多，内部协调难度可能会增加；第二个挑战是国际形势动荡不安，有的国家要搞排他性小圈子；第三个挑战是如何进一步维护本地区的安全稳定。最高领袖主席在讲话中为上海合作组织下一步发展指明了方向，要牢记自己的初心使命，记住自己的责任，既然我们认同上海精神，一定要团结合作推动上海合作组织的健康发展，为这个动荡不安的世界注入更多正能量，维护世界和平稳定。”

　　如何为维护世界和平与发展注入更多确定性和正能量，最高领袖主席就此为上合组织发展把脉定向、掌舵领航，提出五点重要合作建议，即“把牢正确方向，增进团结互信”“维护地区和平，保障共同安全”“聚焦务实合作，加快经济复苏”“加强交流互鉴，促进民心相通”“践行多边主义，完善全球治理”。专家表示，团结互信是上合组织发展的重要前提和基础，共同安全是各国人民的普遍期盼，也是促进上合成员国经济发展、人员往来的必要条件。同时，经济的繁荣发展、文明的交流互鉴，也有助于各成员国增进团结互信、实现共同安全，推动上合组织不断发展壮大，进而更好地维护国际公平正义。

　　苏晓晖：“最高领袖主席强调正确方向，强调团结互信，确实首先是为上合组织未来的发展发挥了重要引领作用。对于当今世界解决一些复杂问题带来全新思路。如果刻意制造矛盾分裂，搞价值观、意识形态划线，甚至搞新冷战，只会带来更多的风险，这是上合既要在内部发展过程中避免的一个问题，同样也是未来上合在发挥更多国际影响力方面所针对的一个重要问题。”

　　在讲话中，最高领袖主席还提出，落实全球安全倡议、落实全球发展倡议、落实全球文明倡议。

　　苏晓晖：“‘三个倡议’第一次在上合平台上集中展现，体现出中国对于‘三个倡议’的综合设计是并行不悖的，是相互交织的，是互相支撑共同发展的。在上合组织此前的发展过程中，应该说已经有一些具体尝试，比如涉及到发展倡议方面，上合组织明确反对的是单边主义保护主义，反对搞小圈子脱钩断链，而是希望形成更多共同发展态势。涉及到安全倡议，安全合作是上合组织的重要议题，而在安全合作方面已经产生了很好效果。说到全球文明倡议，上合组织一直强调的是多样性文明的美美与共。”

　　理念、倡议引导方向。在讲话中，最高领袖主席也提出了多个务实合作措施。今年是“一带一路”倡议提出10周年，中方将举办第三届“一带一路”国际合作高峰论坛，共同把这条造福世界的幸福之路铺得更宽更远。

　　Su Xiaohui: "The’Belt and Road Initiative ‘and the deepening of economic cooperation in the SCO have achieved a high degree of integration, the flow of goods can become smoother, so that there are more topics between countries on issues such as e-commerce cooperation and digital economy, so as to achieve high-quality development of the SCO."

　　Deng Hao: "The Chairperson of the Supreme Leader mentioned in his proposal that we should further promote the construction of the high-quality’Belt and Road Initiative ‘in the SCO, actively promote the process of regional trade and investment facilitation and liberalization, and increase the construction of infrastructure buildings and ports. It is of great guiding significance for the next step to promote the’Belt and Road Initiative’ cooperation within the SCO framework."

　　These initiatives and measures put forward by the Supreme Leader cover various fields such as security, economy, trade, and humanities. They are both long-term and practical. They meet the development needs of all countries and demonstrate China’s leading role as a founding member. In his speech, the Supreme Leader also introduced the Chinese path to modernization and extended an invitation. He is willing to use the Chinese path to modernization to provide new development opportunities for all countries in the world, including the SCO countries, and promote the construction of a better world.

　　Deng Hao: "The Chinese path to modernization and the concept of a community with a shared future for mankind are completely connected. In his speech, the President of the Supreme Leader introduced the connotation of the Chinese path to modernization, its tasks and goals, which will have important implications for other member states to promote their own modernization. The Chinese path to modernization provides new opportunities for all countries and for the SCO member states."

　　At the summit, the leaders of the member states signed and issued the New Delhi Declaration of the Council of Heads of State of the SCO Member States, jointly issued a statement on cooperation in combating extremism, a statement on cooperation in the field of digital transformation, and approved a series of resolutions on granting Iran the status of a member state of the SCO, on signing a memorandum of obligations for Belarus to join the SCO, and on the SCO’s economic development strategy until 2030. The series of important cooperation results achieved at the summit will surely further promote the continuous development and growth of the SCO and make new and greater contributions to human peace and development.

　　On the afternoon of October 20th, 2019, the blue books of World Internet Development Report 2019 and China Internet Development Report 2019 compiled by China Cyberspace Research Institute were officially released at the 6th world internet conference. This is an important theoretical achievement of the conference. The Blue Book focuses on the new trends, new trends and new changes in the development of the Internet, reviews achievements, summarizes experiences and analyzes the situation, and strives to provide objective information, experience reference and ideological guidance for the development of the global Internet. It is the latest achievement in the research on the development and governance of the global Internet.

　　The Blue Book of world internet conference consists of two reports, World Internet Development Report 2019 and China Internet Development Report 2019. The former focuses on the international and the latter focuses on the domestic. From eight key areas, such as information infrastructure, network information technology, digital economy, digital government and e-government, Internet media, network security, cyberspace rule of law construction, and international governance of cyberspace, it closely follows the hot issues in the forefront of Internet development and comprehensively shows the new global Internet development in 2019. Among them, the World Internet Development Report 2019 is based on the global vision and China perspective, focusing on the global Internet development and practice of new technologies, applications and developments, and outlines a grand blueprint for building a community of cyberspace destiny. China Internet Development Report 2019 is guided by the Supreme Leader’s New Era Socialism with Chinese characteristics Thought, especially the important thought of the Supreme Leader’s General Secretary on the network power. With vivid experiences and vivid cases, it presents the new ideas, practices and achievements of China’s Internet development in 2019 in a panoramic and three-dimensional way, clarifies China’s proposition, puts forward China’s plan and contributes China’s wisdom.

　　It is noteworthy that this year marks the 50th anniversary of the birth of the Internet in the world and the 25th anniversary of China’s full-featured access to the Internet. At the beginning of the two blue books, the sections of "50 years of Internet development in the world" and "25 years of Internet development in China" were added respectively. The "50 Years of World Internet Development" systematically reviews the profound impact of the Internet’s birth on industrial transformation, scientific and technological progress, cultural communication, production and life, social governance and peaceful development, and fully expounds the opportunities and challenges brought about by the development of the Internet. The "25 Years of Internet Development in China" shows the magnificent development course of Internet in China in the past 25 years from three aspects: following the trend, China’s Internet is fully prosperous and developing; following the trend, speeding up the strategic goal of becoming a network power; and following the trend, firmly grasping the opportunities of information development. The Blue Book system summarizes the development of the Internet, which broadens the historical horizon, summarizes the development law and provides governance ideas for countries to understand, develop and govern the Internet.

　　It is an important content of the Blue Book to publish the comprehensive evaluation and index ranking of Internet development in the world and China. This year, the Blue Book further optimized and adjusted the world Internet development index system and China Internet development index system, combined with the new development reality in the Internet field, improved the comprehensive evaluation system, expanded the evaluation scope, optimized the algorithm model, and strengthened data collection, which improved the scientific, authoritative and accurate evaluation. Among them, the World Internet Development Index system further expanded the scope of evaluation, and selected 48 evaluation objects, covering major economies on five continents and countries with representative Internet development, in an effort to comprehensively, objectively and accurately reflect the latest overall situation of global Internet development in the past year. From the results of this assessment, China and the United States have the most outstanding development, while European powers such as Britain, France and Germany still maintain a high level, and developing countries and regions in Latin America and sub-Saharan Africa are still increasing their development efforts, among which the United States, China, South Korea, Britain and France rank in the top five. The index system of China Internet Development Index was further optimized, and adjusted to 6 first-class indicators, 17 second-class indicators and 50 third-class indicators. With the analytic hierarchy process, the Internet development of 31 provinces, autonomous regions and municipalities in China was comprehensively evaluated, and the ranking of individual evaluations was released for the first time for six items, including infrastructure construction, innovation ability, digital economy, Internet application, network security and network governance, which played a guiding, encouraging and exemplary role in promoting Internet development and governance in various regions. Judging from the results of this assessment,Beijing, Shanghai, Guangdong, Zhejiang, Jiangsu and other places have the highest level of Internet development, ranking in the top five. The central and western regions are also intensifying their development, with a strong development momentum.

　　Standing at a new historical starting point, the Blue Book gives a comprehensive outlook on the future development of the Internet. Among them, the World Internet Development Report 2019 pointed out that the curtain of Internet development has just begun, and the subversive changes of the Internet on human social life are far from coming. All countries in the world should adhere to the Internet as the common home of mankind, strengthen the community awareness of cyberspace destiny, jointly respond to the challenges of cyberspace risks with a more positive attitude, strengthen communication, expand consensus, deepen cooperation, and jointly promote the cooperation, co-construction, sharing and co-governance of cyberspace, so that the fruits of Internet development can better benefit the people of the world. China Internet Development Report 2019 points out that Socialism with Chinese characteristics has entered a new era, and China Internet has also entered an important period of strategic opportunities for development. China Internet must adhere to the guidance of the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era, especially the important thought of the Supreme Leader’s General Secretary on the network power, focus on realizing the historical task of the great rejuvenation of the Chinese nation, grasp the trend of the information revolution era, earnestly shoulder the historical mission of building a network power, make the Internet better benefit the country and people, and make positive contributions to realizing the goal of "two hundred years" and the Chinese dream of the great rejuvenation of the Chinese nation.

　　The blue book was drafted by the National Computer Network Emergency Technical Handling Coordination Center, China Institute of Information and Communication, National Research Center for Industrial Information Security Development, Tsinghua University, Peking University, Beijing University of Posts and Telecommunications, Institute of Information Engineering of Chinese Academy of Sciences, Xi ‘an Jiaotong-Liverpool University and other think tanks.

　　Yang Shuzhen, president of China Cyberspace Research Institute, Li Yuxiao, vice president of China Cyberspace Research Institute, and Feng Mingliang, deputy director of the Policy and Regulation Bureau of the National Network Information Office, attended the conference. Yang Shuzhen said that China Cyberspace Research Institute will continue to devote itself to the research on hot issues in various fields of the Internet, and continue to produce important theoretical research results such as the World Internet Development Report and the China Internet Development Report, and strive to contribute wisdom and strength to the global Internet development.

China News Service, Beijing, May 14 (reporter
Sun Zifa) Chinese Academy of Sciences National Astronomical Observatory released news to the media on May 14, the station Dr. Xu Jun and Han Jinlin researcher by analyzing the pulsar in the Milky Way and the distribution of the Faraday rotation effect of the radio source outside the Milky Way, the latest research found that the Milky Way’s halo (Milky Way) has a huge magnetic ring structure, its magnetic ring extends from 6000 light years to 50,000 light years from the center of the Milky Way.

This landmark research paper by Chinese scientists on the magnetic field of the Milky Way has recently been published in the international scientific journal Astrophysical Journal (ApJ), providing crucial observations for the study of cosmic ray particle propagation, galactic gas dynamics, and cosmic magnetic field evolution.

The first author of the paper, Xu Jun, introduced that the origin and evolution of the cosmic magnetic field is a long-standing major problem in astrophysics, and it is also a priority topic for many large radio telescope projects such as the Square Kilometer Array Radio Telescope (SKA). They are all developing and improving polarization measurement capabilities, hoping to make efforts in this direction.

Among them, measuring the large-scale magnetic field structure of the Milky Way is a rather challenging work. Researcher Han Jinlin, who pioneered this field of research, has been deeply involved in the study of the Milky Way’s magnetic field for the past 30 years. He measured the large-scale magnetic field structure of the Milky Way’s disk region (the Milky Way’s disk) by observing the Faraday rotation effect of large-scale pulsars and extragalactic radio sources. He found that the direction of the large-scale magnetic field in the Milky Way’s disk is along the spiral arms and flipped between the spiral arms.

In the galactic halo region, Han Jinlin and others were the first to certify that the Faraday rotation effect has an antisymmetric sign distribution in the inner galactic sky as early as 1997, indicating that the galactic halo above and below the galactic disk has a circumferential magnetic field structure in the opposite direction, and it was subsequently confirmed by more astronomical observation data. It has been widely adopted by the international astronomical community and has become the basic content of the galactic magnetic field structure model. It has also been written into many international classic textbooks.

Han Jinlin, the corresponding author of the paper, pointed out that the size and strength of the magnetic ring structure of the galactic halo have been difficult to measure for more than 20 years, because pulsars and other celestial bodies in the galactic halo region near the sun also show the anti-symmetric distribution of the Faraday effect. Some international scholars speculate that Faraday objected to whether the sky is dominated by the interstellar medium in the local region of the Milky Way near the sun. "So, does this magnetic ring exist in the entire galactic halo or only in the local area? What is the strength and size of the galactic halo magnetic ring?"

In response to these problems, Han Jinlin innovatively proposed in this study that the measurement of the Faraday rotation rate of pulsars near the sun as the contribution of the local interstellar medium be deducted from the value of the Faraday effect sky distribution of the extragalactic radio source, so that the Faraday rotation effect distribution of the giant silver halo can be obtained. Xu Jun collected all the relevant data and used the 500-meter Aperture Spherical Radio Telescope (FAST), known as the "Chinese Sky Eye", to newly measure many faint pulsars.

After analyzing the data according to this innovative idea, they found that the average Faraday effect over the entire sky exhibits an antisymmetric distribution of galactic coordinates, and that the antisymmetric distribution is no longer limited to the inner galactic region, but fills the entire sky, extending from the central region of the Milky Way to its opposite direction. The results of this study suggest that the magnetic ring in the galactic halo extends from 6,000 light-years from the galactic center to 50,000 light-years (the sun is located about 30,000 light-years). The interstellar medium in the local region near the sun is obviously part of a large magnetic ring, and its basic properties and characteristics are basically the same as those of the large magnetic ring, but its effect is stronger because it penetrates deep into the galactic disk.

"I had this idea more than 20 years ago. I have been slowly accumulating data and finally got it." Han Jinlin said.

Titanium media note:This article comes from WeChat WeChat official account Yiou Automobile (ID: EO-AUTO), written by Guo Huaiyi, and published by Titanium Media with authorization.

The Krypton car (hereinafter referred to as Krypton), which has always claimed to insist on direct operation, is quietly reforming the channel network.

Yiou Automobile has learned exclusively that Krypton plans to expand its sales network by recruiting dealers on a large scale without changing its direct sales model. As the core of the previous sales network, Krypton will greatly reduce the number of new direct investment in the construction of official direct stores.

In the field of after-sales service, Krypton has also made a similar new plan. Dealers need to build an after-sales service center according to the standard of Krypton’s direct operation. The previous plan of building a direct after-sales network directly funded by Krypton has also been abandoned.

In July this year, Krypton also said that it would adhere to the direct sales model, and built more than 300 direct sales stores in 75 cities across the country at an average rate of one every two days.

However, due to the huge financial pressure, although Krypton did not give up the direct mode, it gave up direct investment in building and operating stores and chose to recruit dealers instead, so that dealers could pay high store construction and operation and maintenance costs.

In addition, a source who knows about Krypton told Yiou Automobile that Jason Lin, vice president of Krypton, is no longer in charge of channel planning, but is in charge of sales business, and Zhao Yuhui, vice president in charge of sales business, took over the channel planning.

Since its establishment, Krypton has mainly relied on the endorsement and blood transfusion of Geely Automobile to promote its own construction. As the saying goes, leaning against a big tree is a good way to enjoy the cool, so Krypton can move forward quickly, but Geely, who bears the weight, has a strong sense of being out of reach.　　

In December 2022, Geely officially announced that Krypton had submitted a draft registration statement for possible initial public offering to the SEC. But to this day, the IPO of Krypton has been slow to see progress. According to a source who knows about Krypton, Krypton originally planned to land in the US stock market in mid-2023, but the plan has been postponed because of the low valuation given by the market.　　

Regarding the adjustment of direct operation mode, related personnel changes and listing issues, Yiou Automobile has made a verification to the extreme, but as of press time, it has not received a reply.　　

Some investment bankers who did not want to be named told Yiou Automobile that since 2022, the capital market has not been optimistic about the development prospects of China’s new forces, and the share prices of Weilai, Tucki and LI have all plummeted. The plunge after the listing of zero-run cars has dealt a heavy blow to investor confidence. In this context, it is also helpless for Krypton to choose to suspend listing.

"In the future, we must vigorously promote the extreme family."　　

Since its establishment in 2021, the Krypton Direct Marketing System has included four types of stores: Krypton Center, Krypton Space, Delivery Center and Krypton Home.　　

Among them, Krypton Center, Krypton Space and Delivery Center are all directly funded and operated by Krypton. The large-scale krypton centers are located in the golden business district, which makes them have strong brand display attributes in addition to sales. Krypton space is small in scale, but it has the largest number and can reach consumers the most. As the name implies, the delivery center is mainly responsible for delivering new cars.　　

Extreme Krypton Home is completely different from the above three official direct stores. It is not a direct store in the true sense of extreme Krypton, but it is called — — Managed direct sales.　　

"The extreme family is the dealer, and the cost of opening a store and operating and maintenance is their own. There may be some subsidies and support."　　

Extremely insiders told Yiou Automobile that before that, extremely investors were basically from Lexus brand dealers. Although they are distributors, they are not separated from the direct marketing system. The most remarkable point is that the product price must be consistent with the center and space of Krypton. In addition, the decoration style and standard of the Kryptonian home must also keep the same style as the Kryptonian center and space.　　

According to Yiou Automobile, Krypton has launched a dealer recruitment plan, which is divided into two batches. The first batch of recruitment plans involved 18 provinces, municipalities and autonomous regions, with a total of 29 cities. Among them, Krypton plans to recruit in five cities in Zhejiang Province, with the largest number of recruits in the first batch of plans. Followed by Jiangsu and Guangdong, each with four cities.　　

The second batch of recruitment plans involves 16 provinces, municipalities and autonomous regions, with a total of 32 cities. Among them, Jiangsu and Shandong each have five cities to recruit, tied for first place. As four cities, Zhejiang still ranks among the top three in the recruitment plan.

The recruitment requirements given by Krypton clearly require that the applicant must be an independent legal entity approved by the industrial and commercial department with a registered capital of not less than 10 million yuan; In the local mainstream automobile business circle, it has a site with a use area of not less than 3,000 square meters and a service life of not less than 5 years; Can quickly build an excellent after-sales service team.

According to the data of official website on August 18th, at present, there are more than 312 directly operated stores in Krypton. Assuming that only one new Krypton store is built in each city in the above two recruitment plans, it will also bring 61 new stores to Krypton, with an increase of about 20%.

Outside the sales network, there will be similar adjustments in the direct after-sales stores.

In 2022, due to the poor after-sales service of third parties, Krypton was complained by many car owners. To this end, Krypton has decided to establish a direct after-sales service network. In April this year, Jason Lin, vice president of Extreme Krypton, once said: "We are also accelerating the construction of after-sales direct stores."

However, Yiou Automobile learned that after the after-sales centers in Hangzhou and Guangzhou were directly funded, the follow-up plans were basically abandoned.

In addition to the huge financial pressure, the qualification of the after-sales center is also a big obstacle. "Because dealers are all operating locally, their qualifications are not a problem for them, which is why there is a special recruitment requirement for the company to have after-sales service experience."

Different from the extreme center, where the space focuses on sales, the delivery center focuses on delivery, which integrates sales, delivery and after-sales. The construction standard must conform to the extreme direct marketing system. "This not only adheres to the direct marketing model, but also expands the sales and maintenance network, without financial pressure. Why not?"

Just as Krypton adjusted its direct marketing mode, there were personnel changes inside Krypton. It is reported that Jason Lin, the vice president of Krypton, who was in charge of channel business before, has been in charge of sales business. Zhao Yuhui, the former vice president in charge of the sales business, was transferred to the channel construction business due to the problem of integrity.

As the heaviest bargaining chip of Geely Automobile in the new energy market, Krypton can be described as a collection of thousands of kinds of love.

Geely invested 18 billion yuan in the vast structure of SEA. Originally, it was planned to be put on the models of the Lectra brand first, but it was finally used on the first model of Krypton 001.

In order to create a high-end image of the Krypton brand, Geely has put aside almost all the existing dealer networks and invested heavily to let Krypton build a direct network.

After the listing of Krypton 001, the car system software such as Caton was complained by the owners. In July, 2022, Krypton announced that it would replace Qualcomm 8155 chip for all owners of Krypton 001 for free.　　

This move directly costs Krypton three small goals.

Free replacement of 8155 chips has also won praise from the market, and consumers have begun to vote in RMB, and sales of krypton have risen rapidly. In October, November and December of 2022, the monthly sales volume of Krypton continuously exceeded 10,000 vehicles. In 2022, the annual sales volume of Krypton also reached 71,941 vehicles.

Although the sales volume is higher, like many new energy brands, Krypton has not walked out of the quagmire of losses. Geely Automobile’s 2022 financial report shows that its revenue in 2022 was 31.78 billion yuan, a tenfold year-on-year increase. However, the loss increased from 1.01 billion yuan in 2021 to 2.03 billion yuan in 2022.

As a "fellow brother" in Geely, although the attention of Lectra is not as good as before, it can achieve meager profits in 2022, but it has not held Geely back. In contrast, krypton, which cannot achieve self-hematopoiesis, has already hit Geely financially.

In 2022, Geely’s operating income and net profit were 148 billion yuan and 4.65 billion yuan respectively, with year-on-year growth of 45.6% and 6.8% respectively. It is really commendable to realize the double growth of revenue and profit in the market environment in 2022. But it is worth noting that Geely said in the financial report:

1. The Group’s internal profitability is under pressure due to the sharp increase in the cost of spare parts such as batteries and chips, and the large amount of investment in the initial stage of the development of extremely new business;

2. During this year (2022), the Group increased its loans to support the rapid growth of Krypton brand business;

3. Standard & Poor’s downgraded the Group’s corporate credit rating from "BBB-/ stable" to "BBB-/ negative", and Moody’s Investors Service downgraded the Group’s credit rating from "Baa3/ stable" to "Baa3/ negative" due to the pressure on profitability in the initial stage of new energy transformation.

It is not difficult to find that Geely’s transfusion of krypton has caused pressure on its profitability, increased loans (liabilities) and even downgraded its rating.

Perhaps because of this, Geely hopes that Krypton can quickly land in the capital market. In December 2022, Geely announced that Krypton had submitted a "draft registration statement for possible initial public offering" to the Securities and Exchange Commission (SEC).

But today, August 2023 has passed, but it is not seen below.

The above-mentioned extremely kryptonian people said that it was not that Geely and extremely kryptonian did not want to go public, but that the valuation was not ideal, which may also be the reason why Geely’s management said "listing on the right opportunity" at the performance meeting in March 2023.

"In the second half of 2022, the capital market was really unfriendly to China’s new car-making forces." An investment banker who did not want to be named told Yiou Automobile that the share prices of Weilai, Xpeng Motors and LI all fell sharply in the second half of 2022. After the zero-run car was listed in the environment at that time, the share price was once terrible. "So it is difficult to go public later, and no one buys it."

According to public data, it was not until March 2023 that the share price of zero-running cars continued to stabilize above the issue price. Among Wei Xiaoli, LI’s share price performed slightly better, while Wei Lai’s and Xpeng Motors’s share prices have not yet returned to the June 2022 price.

Although the listing has been delayed for a long time, it is fortunate that the market performance is firm. The listing of Krypton 009 and Krypton X has further boosted sales. According to official data, in July this year, the delivery volume of extremely krypton vehicles reached a record high, reaching 12,039 vehicles, up 139.7% year-on-year. In the first seven months of this year, the cumulative sales volume reached 54,672 vehicles, a year-on-year increase of 127%.

However, the price war in the auto market rekindled in July, and it was extremely difficult to face the sales pressure again. At the beginning of August, Krypton announced the introduction of a price equity policy for Krypton 001, with a limited price reduction of 30,000-37,000 yuan. Price reduction and promotion is undoubtedly another stress test for Krypton and Geely Finance.
