On January 18, 2024, Huawei announced that the developer preview of HarmonyOS NEXT Hongmeng Galaxy Edition is open to developers, which means that the Hongmeng ecosystem has entered the second stage, which will accelerate the application of Hongmeng in thousands of industries.

Yu Chengdong, executive director of Huawei, CEO of End Point BG, and chairperson of BU Smart Car Solutions, announced the latest progress of Hongmeng Ecology: The number of Hongmeng ecological devices has increased from 700 million to 800 million in 5 months, and all kinds of industries are connected, which will open a new blue ocean of trillion-level industries. At present, the first batch of more than 200 application manufacturers are accelerating the development of Hongmeng native applications. Yu Chengdong said, "In 2020, it is proposed that’no one can extinguish the starlight in the sky ‘. With the joint efforts of many partners and developers, the trend of Hongmeng Ecology has become a reality. As a full-scene operating system for the Internet of Everything, Hongmeng Ecology belongs to every developer."

It is reported that Hongmeng has been building a full-scene operating system for nearly ten years since the project was established in 2015. At present, Hongmeng system has been running on many full-scene devices. HarmonyOS has taken root and broken through the core technologies of operating system kernel, AI big model, AI framework and compiler, programming language, etc., laying a solid foundation for ecological construction. In particular, Hongmeng kernel, beyond the traditional kernel, has the characteristics of more flexibility, more security, more fluency, and more adaptable to the diversity of all-scene devices.

The Hongmeng Galaxy Edition, which is currently open to developers, will create the ultimate experience of native delicacy, native ease of use, native fluency, native security, native intelligence, and native interconnection. Hongmeng will also become an operating system that connects hardware, scenes, supports diverse interactions, and circulates freely.

Since Huawei announced the upcoming release of HarmonyOS NEXT in September 2023 and the full launch of Hongmeng native applications, the first batch of more than 200 Hongmeng native applications has been accelerated, covering convenient life, travel and tourism, financial convenience, social information, productivity tools, audio and video entertainment, games and other fields. The Hongmeng native application landscape has basically taken shape. At the same time, Ant Group, China UnionPay, iFLYTEK and other partners have also opened up vertical innovation capabilities. Together with Huawei’s base capabilities, it provides developers with an efficient full-link power builder. The development workload can be reduced by up to 90%, helping the industry accelerate the development of Hongmeng applications. Partners can also quickly access the Hongmeng ecosystem through the minimalist development of meta services.

A steady stream of talents is also an inexhaustible driving force for ecological growth and advancement. In terms of talent training, 305 college students have participated in Hongmeng activities, Hongmeng campus open courses have entered 135 colleges and universities, 286 enterprises have participated in Hongmeng Ecological Academy, 380,000 + developers have passed Hongmeng certification, and more than 150 industry-university cooperation projects have provided a well-stocked "granary" for the continuous innovation and prosperity of Hongmeng ecology.

Hongmeng is a new ecosystem facing the all-scenario era. With the Hongmeng ecosystem entering the second stage, Huawei expects to join hands with more developers to accelerate the application of Hongmeng in thousands of industries.

At present, under the distribution of Hongmeng’s full-scenario service, 87.6% of the required cockpit operations will be completed by Xiaoyi; the number of mobile phone Xiaoyi MAU users has exceeded 200 million, and the intention items covered by Xiaoyi scene cards have exceeded 100. A new ecosystem of "everything is a service, everything can be shared" has been formed.

The end-cloud collaborative native intelligence feature of Hongmeng Galaxy Edition can not only benefit users, but also support applications to use large model capabilities efficiently and safely. As low as "one line of code", Hongmeng native intelligence can be called, allowing developers to apply "zero-cost" AI. In addition, relying on the new "heterogeneous native" parallel mechanism of Hongmeng Kernel, it can make the kernel extremely smooth and improve the efficiency of memory management by 3 times.

Hongmeng’s internal nuclear-level security capabilities have been certified by the industry, and through innovative privacy architecture, the pop-up authorization has been greatly reduced, reducing the risk of privacy leakage from the root cause, enhancing consumers’ perception of privacy protection in an all-round way, making the experience simpler and privacy more secure.

In order to further boost the development potential of Hongmeng’s ecosystem, Huawei announced the "Yaoxing Plan" to invest 7 billion yuan to encourage Hongmeng developers to innovate in Hongmeng’s native applications, meta services, SDK, etc. At the same time, Huawei will work with partners to rely on Hongmeng Ecological Academy, universities to jointly cultivate Hongmeng talents, and cities to release Hongmeng talent training policies to cultivate 100,000 Hongmeng developers every month. And announced the opening of the 2024 HarmonyOS Innovation Competition, providing developers with an open API for training and continuous advancement through competitions.

Hongmeng Galaxy Edition is expected to release a developer beta version in Q2 2024, and a commercial version for consumers in Q4.

　 　 In 2013, Xiaomi launched its first smart TV product, which has now reached the fourth generation. The TV system is also constantly being upgraded and evolved. New and old models have been equipped with or upgraded to the PatchWall puzzle wall system. The following small settings may make your Xiaomi TV easier to use.

1. Commonly used software is placed on the first screen

　 　 Although Xiaomi TV has assembled several video platforms, it still has certain limitations in terms of resources, so it is still necessary to install some third-party video software. Of course, the simpler the steps to open these software, the better.

Put the software at the top and it will appear on the first screen.

　 　 The software entrance of Xiaomi TV is located on the homepage of the desktop, but only 5 icons will be displayed, and the others will be folded in "More". The newly installed software will be automatically arranged backwards and will not be displayed on the homepage. At this time, you only need to click "Sort" above to put the commonly used software at the top, so that they can appear on the homepage. Each time you open it, you don’t need to look for it for a long time.

2. Automatically clean up TV waste

　 　 The current Xiaomi TV basically comes standard with 2GB of memory + 8GB of flash memory, which is enough under normal circumstances, but it will occasionally feel stuck after using it for a period of time. After all, it is the Android system. At this time, you can use the built-in "one-click acceleration" and "one-click cleaning" tools of Xiaomi TV.

TV Butler turns on automatic cleaning

　 　 In fact, there is no need to wait for the TV to change the card before using these two tools. In the "TV Butler", automatic cleaning can be turned on, and the cleaning frequency and cleaning timing can be customized, which saves a lot of trouble.

3. Remote control wired set-top box

　 　 A few months ago, along with the arrival of the Xiaomi TV 4A came the latest generation of Bluetooth touch voice remote control. The voice function goes without saying. This remote control, which sells for 99 yuan, also has a very magical function. It can control the cable TV set-top box at home, thus eliminating the need for frequent switching between the two remote controls.

The binding process of TV remote control and cable set-top box

　 　 How to do it? First, you need to enter the display interface of the set-top box, press the menu button of the remote control, and select "Bind the set-top box" on the pop-up interface. According to the prompts on the TV, after setting the city and region where you are located and the operator of the cable TV set-top box, you can start matching, and the matching will be successful soon.

Voice Switch

Press the OK button to enter the live TV wall.

　 　 After matching, you can use the up and down buttons of the Xiaomi remote control to change the channel. At the same time, it also supports voice change. If you directly say the channel you want to watch, it will automatically jump. In addition, if you press the OK button of the remote control, a live TV wall will appear, which will display the current live program information. It is much more convenient than using a wired remote control. The only inconvenient point is that you cannot control the opening/closing of the set-top box.

4. Block boot ads

　 　 Xiaomi TV now has 15/30 second advertisements when it is turned on, and many other smart TVs are basically the same. In fact, you can make the boot advertisements no longer appear through settings.

　 　The setting needs to be carried out on the router. The router must have the function of URL blocking. After entering the router management background, add the above URLs to the blacklist, so that the TV will no longer receive advertisements.

　 　 If you find other interesting skills when using Xiaomi TV, please leave a message to share. ■

Pay attention to bubble network, enjoy technology life.

"Tencent is losing its product capabilities and entrepreneurial spirit, and becoming an investment company…" These days, an article signed "Pan Chaos" and titled "Tencent has no dreams" has been very popular on the Internet. The article said that "this nearly 20-year-old company (referring to Tencent) is becoming utilitarian and short-sighted, and his strength is no longer product business, but investment in financial technology"; and analyzed some of Tencent’s less successful products and more successful investment cases in recent years, and came to the conclusion that "Tencent has no dreams".

?

The criticism was directed at Tencent, one of China’s leading Internet companies, so after the article was published, it quickly spread across the Internet and the venture capital community. The story that followed was even more twists and turns: first there was a response from Tencent President Martin Lau, and then there was a response from Tencent CEO Pony Ma: "Look, it’s good to have criticism…" But when everyone was discussing whether Pony Ma’s response could explain the problem, Zhang Jun, Tencent’s public relations director, clarified that "Pony Ma’s response" was fake and was the result of PS (photo processing).

?

Zhang Jun clarified in Moments that Ma Ma’s response was PS

?

This clarification did not reduce the popularity of "Tencent has no dreams", because ordinary users who use WeChat and QQ to play "Honor of Kings" and "Jump" are still interested in exploring the answer to the question "Does Tencent have a dream". So, does Tencent have a dream?

?

The industry applauds the open attitude

?

Judging from the evaluation information of Tencent insiders, although they do not agree with the whole of "Tencent No Dream", they generally adopt an inclusive attitude. For example, the discussion between Lau Chiping and Zhang Jun on WeChat Moments shows that Lau Chiping believes that "Tencent is a bigger organization and ecosystem than the author imagined… [The article] simplifies Tencent into a product gain and loss, a strategic deployment, and a person’s will. It is too narrow… The title and conclusion are distorted because they are trying to catch the eye." But he also made it clear: "But there are still some unique insights that can be used as reference and supervision." Zhang Jun said: "We listen to the voices of the outside world, absorb them, and transform them into stronger action forces."

?

Dialogue between Martin Lau and Zhang Jun at Moments

?

Zhang Jun’s attitude towards "Tencent has no dreams"

?

Industry observers also feel that "Tencent No Dreams", although flawed and the conclusion may be questionable, is a "work of conscience". Ma Qiji, former senior vice-president of Nielsen Internet Research and a research fellow at Peking University’s New Media Marketing and Communication Center, commented: "This is a good article [referring to’Tencent No Dreams’]. Although the argument method and logic are slightly flawed, it is still done with all its heart. It is essentially a commentary on Tencent’s strategic goals, path selection and organizational system, not’dream theory ‘." It’s just that he feels that "unless there is a very deep understanding, research, analysis and research on this kind of topic, it is difficult to have a real understanding and judgment of Tencent’s real behavioral starting point and consideration, let alone an effective and incisive discussion."

?

Many Internet practitioners believe that "Tencent has no dreams" is heating up online, but Tencent’s various dissemination channels, including WeChat, QQ, etc., have not "blocked" this article, at least indicating that Tencent is a company willing to listen to different voices, and should be praised for this attitude.

?

"The problem with many internet companies is that they are not open enough. Whether they are start-ups or industry leaders, they always think that they are standing on the high ground of innovation and are held in the palm of the hands of the crowd, so they cannot listen to criticism. Once someone criticizes, in addition to directly refuting or trying to’block ‘, sometimes they will use’water army’ to whitewash themselves. This approach should be praised for Tencent’s tolerant attitude. This also reminds other internet companies that they should have the heart to listen to different voices, and if there is no change, they should be encouraged, so as to make progress." Internet observer Tang Zhao said.

?

From corporate dreams to connectivity tools

?

As of press time, Tencent officials, including Pony Ma, have not made any further comments on "Tencent has no dream". However, the industry believes that from the recent layout of Tencent, it has actually responded with actions: launching "explosive" products or services is no longer its focus, and using Tencent’s existing resources and capabilities to connect all walks of life and achieve upgrades in all walks of life may be one of Tencent’s "dreams".

?

At the recent Digital China Construction Summit, Pony Ma summarized what Tencent is and will be doing in four numbers in his speech: "One goal" is to be a good assistant. "We hope to do something and not do something – not to enter all walks of life and replace it; but to become a’digital assistant ‘in all walks of life." Three things "means that Tencent will focus on connecting, making tools and doing ecology." Five areas "refers to the scope of Tencent’s efforts, including people’s livelihood and government affairs, living consumption, production services, life and health, and ecological protection. Finally, there are the "seven tools" that Tencent provides to all walks of life: WeChat official account, WeChat Mini Program, mobile payment, social advertising, WeCom, big data cloud computing artificial intelligence, and Tencent’s security capabilities.

?

Ma Qiji believes that even a big company like Tencent does not need to talk about "dreams": "Not every company has or needs a dream. The’Tencent dream ‘is a good but unrealistic wish, and it has been crooked from the beginning, so the discussion [of’Tencent has no dream’] has become trivial." He personally believes that "Tencent is a good leader by connecting and empowering, building the belief and imagination of the future, and establishing resource allocation and public input." He also added: "I personally like Tencent’s recent formulation of’technology for good ‘, so my dream is: Tencent can help everyone strive to get close to it (technology for good)!"

?

?

How many people can the "connection tool" realize their dreams?

?

In fact, the reason why there is the question or discussion of "Tencent has a dream" is not unrelated to the development of Tencent in recent years. From the perspective of specific products, since the launch of "popular" WeChat, Tencent is not without innovation, but many products that are popular in the market are closely linked to WeChat, including WeChat red envelopes, WeChat Pay, WeChat official account, WeChat Mini Program, but the outside world regards them all as "WeChat", rather than new achievements. At the same time, Tencent’s investment has been "fruitful", and the listing of invested companies such as ZhongAn Insurance, Sogou, China Literature, and Yixin Group has brought tens of billions of dollars to Tencent.

?

In comparison, Tencent’s achievements as a tool to connect other industries seem less obvious; or even if the connection is successful and produces results, many people do not know that they are related to Tencent. However, a little review of some of Tencent’s recent "connection" achievements reveals a lot of surprises.

?

For example, Tencent recently entered into a strategic partnership with the World Wildlife Fund (WWF) to launch digital conservation efforts. In Shenzhen Bay, after a user’s mobile phone QQ scans the sculpture in front of them, several white dolphins will jump up from the "water" and swim around. It turns out that this is a "digital landmark" project explored by the two sides. In the future, when people walk, bike or sightseeing along the coast of Shenzhen Bay, they can pass by more similar magical sculptures or devices. Open the mobile phone QQ to "scan", and dolphins will play to their heart’s content, or birds will circle and pitch on the screen. More importantly, people can also learn about these beautiful creatures: "There are only about 2,000 Chinese white dolphins left in China, living in the Pearl River estuary; the black-faced spoonbill is a bird in Shenzhen, and the population is extremely rare; they are all state-level protected animals and the aborigines of Shenzhen Bay…" WWF related people believe that such "digital landmarks" not only belong to Shenzhen, but also belong to the world. Through the exploration with Tencent, more cities and regions can have their own "digital landmarks", allowing people to feel the wonder and beauty of nature more strongly, and arousing the public’s awareness of protecting the ocean and caring for endangered animals. This case may make many nature conservationists "dream come true".

?

There is also the "digital classroom" created by WWF and Tencent, which may fulfill the dream of many ecological rangers. It turns out that there are more than 370,000 ecological rangers in China, who are the most basic guardians and main force of national parks, cruising day after day to eliminate fire pests and stop poaching. However, due to the dispersion of personnel and the lack of training teachers, how to better train these rangers has become a problem. The "digital classroom" will introduce WWF’s rich and high-quality content to provide online training courses for ecological rangers and other practitioners, including relevant laws and regulations, wildlife identification, wild survival knowledge, etc., so that they have more professional knowledge and skills, and have more safety when walking in the forest.

?

In fact, after the spread of "Tencent No Dream" exceeded 1 million, Pan Chaos also sent a paragraph in his circle of friends: "Tencent has no dream, Tencent has achieved the dream of many people…" A Tencent grassroots employee sent reporters his thoughts after watching "Tencent No Dream": "Tencent will never be perfect, but fortunately it has been evolving – because there are many young people chasing dreams here, and it is also becoming the dream of young people."

?

Pan’s Confession in Moments

?

Perhaps it is more practical for more people to realize their dreams with the help of technology than whether a company has a dream.

The national automobile brand Hongqi is a household name. From annual sales of less than 5,000 vehicles to production and sales of more than 300,000 vehicles, from single models to diversified models… In recent years, under the background of the transformation and upgrading of the global automobile industry, China FAW Group Co., Ltd. has stimulated corporate vitality and improved operational efficiency through reform, and strived to explore the road of high-quality development. At present, FAW is comprehensively promoting electrification, intelligence, and networking to expand the upward development space of national automobile brands.

Reform, let FAW "reborn"

Yang Yongxiu is a senior technician at FAW Research and Development Institute. In recent years, FAW’s accelerated reform has given him more room to display his talents. He is mainly responsible for the numerical control processing of core precision components such as high-end engines, gearboxes and chassis independently developed by Hongqi. He has overcome more than 130 technical problems and saved and created more than 12 million yuan of value for the group company. At the age of 35, he has won honors such as National Technical Expert and National May Day Labor Medal.

"There are still many young people like me in FAW, and the stage will be as big as everyone’s dreams, technology and ability," he said.

In 2017, FAW carried out the "four-energy" reform, that is, "cadres can go up and down, employees can come in and out, salaries can be high and low, and institutions can increase and decrease". The whole group competed for recruitment, senior managers competed for positions, the average age dropped by 3 years, and the proportion of young cadres increased by 13.3%. At the same time, the market-oriented reorganization of the organization formed a more professional, fine and flat structure and operation model, and the group headquarters was directly responsible for the operation of the Hongqi brand.

The reform has stimulated a sense of competition, and FAW employees have become more motivated. It has become a general consensus to compete for jobs, and the sense of crisis has also increased.

In September 2020, FAW implemented a more systematic reform of the new three-year term of office for senior managers, setting goals first and then taking up positions, and encouraging challenges to high goals. The matching of senior managers was completed within a week, and the average age of cadres was reduced by 1.4 years. According to the plan, these reform measures will continue during the "14th Five-Year Plan" period to continuously stimulate employees’ enthusiasm for entrepreneurship.

Innovation makes FAW "alive and kicking"

Since the establishment of the Hongqi brand in 1958, it has become one of the representatives of China’s national automobile high-end brands, but its marketization road has not been smooth sailing. Since 2018, Hongqi has highlighted the brand core and created four product series of L, S, H and Q. Sales will exceed 300,000 in 2021, an increase of more than 60 times in 4 years.

Behind this, it is inseparable from the corporate culture that places more and more emphasis on innovation. After the launch of Hongqi H9, H9 + models were also launched one after another. H9 + models are divided into Dunhuang version, Magnolia version and Forbidden City version. These models are combined with traditional Chinese culture, which is refreshing.

In the first two months of this year, the red brand sold 63,800 units, an increase of 40% year-on-year.

The sales volume of the Hongqi brand depends not only on marketing, but also on the support of technology. FAW’s total R & D investment in 2021 was 21.42 billion yuan, an increase of 3.9% year-on-year, accounting for 3% of revenue; it achieved 63 key core technology breakthroughs and completed 4,757 patent applications. Among them, the first domestic V-shaped 8-cylinder direct injection supercharged (referred to as "V8TD") engine independently designed by FAW completed trial production last year, reaching the leading level of similar models in the world. The domestic snowmobile jointly developed by FAW and China Aerospace Science and Technology Corporation Co., Ltd. broke the long-term monopoly of foreign brands on the Chinese snowmobile market.

FAW Party Secretary and Chairperson Xu Liuping said that each Red Flag product must have more than two global premiere technologies, otherwise it will not pass the product definition.

Open up, let FAW "walk in the forefront"

Xu Liuping said that Hongqi aims to become the leading independent high-end passenger car brand, and FAW is committed to building a global brand influence.

At the end of February, FAW and BYD joint venture power battery project officially started, the total investment of the project 13.50 billion yuan, all reached the post-production will meet the 1 million sets of electric vehicles supporting demand, to achieve output value of more than 20 billion yuan. Wang Chuanfu, chairperson and president of BYD joint stock company, said that BYD will strengthen cooperation with FAW, accelerate the transformation of green technology to the nearest landing, and contribute to making the national car brand bigger and stronger.

Cooperation can lead to win-win results. FAW has carried out in-depth cooperation with Huawei and other enterprises, as well as universities such as Tsinghua University and Jilin University, to expand the development space of enterprises.

The interaction between government and enterprises is also accelerating FAW’s "walking in the forefront". Jilin Province, Changchun City, FAW and State Grid jointly launched the "Banner E Spring City, Green Jilin" project, and strive to use 3 years to put 34,000 new energy taxis, online car-hailing, official vehicles, to achieve "battery bank" circulation battery 41,000 block scale, and 120 new operation and exchange power stations.

According to the plan, by 2025 FAW will achieve sales of more than 6 million vehicles, an average annual growth of about 8%; operating income of more than one trillion yuan, an average annual growth of 8% to 9%.

On November 30, Meituan announced its third quarter 2020 financial results.

According to the financial report, during the reporting period, Meituan achieved revenue of 35.40 billion yuan, an increase of 28.8% year-on-year and an increase of 43.2% month-on-month. Achieved profit of 6.32 billion yuan, an increase of 374.1% year-on-year. Excluding the impact of fair value changes, profit and loss, the company’s adjusted net profit in the third quarter was 2.05 billion yuan, an increase of 5.8% year-on-year.

From a business perspective, Meituan’s catering takeaway business earned 20.69 billion yuan in the third quarter, an increase of 32.8% year-on-year; contributed 770 million yuan in operating profit, an increase of 132.2% year-on-year, and an operating profit margin of about 3.7%;

The revenue growth rate of the store, hotel and tourism business was 4.8%, generating an operating profit of 2.79 billion yuan, an increase of 19.5% year-on-year, and an operating profit margin of 43.0%.

New business and other businesses lost 2.03 billion yuan, an increase of 68.8% year-on-year.

Meituan handed over the third quarter report card, which can be described in four words: steady and steady. This financial report truthfully reflects the operating performance of Meituan company so far, and the overall performance is good.

However, I didn’t expect this financial report to be interpreted differently by various media for no reason. Meituan’s third-quarter results were described as a bit "flashy".

Clear the clouds and see the sun

The problem actually lies in the "change in fair value of investment listed entities RMB 5.80 billion yuan" disclosed in the financial report.

The proceeds were primarily derived from Meituan’s investment in Li Auto.

Previously, Meituan led Li Auto’s $550 million D round of investment, and Li Auto went public in the United States on July 30 this year. In the third quarter, Li Auto rose by more than 30%; and the ideal share price in the fourth quarter has also been performing well.

So some people bluntly said that Meituan’s performance depends entirely on "ideals".

With the media further hype brewing, the news about Meituan’s third-quarter earnings report in the past few days has actually formed a situation of "every Meituan must mention ideals".

Not only that, but various media also focused on the loss of new business in the financial report. Combining the increase in new business losses year-on-year and the profit of investment ideals, it was concluded that "Meituan actually did not perform well, and investment ideals were the’fig leaf ‘for its new business losses".

So much so that there are good people who write this matter into a joke, which is ridiculed by netizens.

But in all fairness, is Meituan really so "unbearable"? Now there is a threshold for the interpretation and analysis of financial reports?

So, what exactly does Meituan’s third-quarter earnings report show?

"Investing" is a normal operation

First of all, Meituan’s investment in Li Auto was successful and profited from it. This is indeed an objective fact.

In fact, contrary to what many media understand, this represents that Meituan has excellent investment vision and strategic thinking in the layout of cutting-edge technologies. Success is natural.

Investment is a normal behavior in business operations, and usually there are two main purposes for this kind of investment. The first is to lay out the layout of your own business ecosystem; the second is to broaden the company’s revenue channels, so as to obtain enough resources to expand your own business.

When a company reaches a certain scale, its business development must pay attention to layout and ecology. But to build a good ecosystem, it is often not covered by its main business.

So Meituan’s investment ideal has reaped profits. Although it seems to be a "cross-border", it is essentially based on Meituan’s long-term value judgment of an industry and supplements its own strategy and business.

New business strategic loss

Another question about Meituan is the loss of new business.

Meituan’s third quarter 2020 financial report shows that the new business and other items achieved revenue of 8.23 billion yuan, but the operating loss was 2.03 billion yuan, an increase of 68.8% year-on-year.

If it is foolish to regard the investment ideal as a "fig leaf", then combining the loss performance of Meituan’s new business with the investment ideal, saying that Meituan has many operational problems is bad.

Although "net profit" and "net loss" are indeed important indicators to measure a company’s performance in a company’s operations, they are not the "only indicator".

In short, a company’s loss doesn’t necessarily mean "the company is going to die".

Meituan’s new business and others mainly include shared bicycles and Meituan’s preferred business launched in July this year, which marks Meituan’s official entry into community group buying.

Wang Xing revealed that Meituan plans to cover more than 1,000 municipalities by the end of the year. And Meituan needs to better integrate resources, provide better products and improve supply chain and logistics.

In addition, Meituan is also responsible for developing various services and products in the entire platform system in order to optimize the user experience.

Sanyan Finance also reported in previous articles that "community group buying" has become a must for major Internet Tech Giants.

So to start a business in a new field, it is necessary to invest huge resources in the early stage. However, the investment is huge, and the return is not immediate.

So it is common for new business to lose money, otherwise how can it be called "new" business?

Furthermore, Meituan’s new business revenue growth just shows the hard power that Meituan has been accumulating "steadily". Because if there is no strong foundation laid by the previous development, how can you invest resources in the new business to seize the market and compete with other Internet Tech Giants?

Therefore, the ideal investment and new business losses not only fail to prove that Meituan "has no martial arts ethics" and relies on Li Auto to cover up the losses, but also prove that Meituan is an Internet company with unique vision and hard power.

Explore old businesses and develop new ones

Putting aside the misreading of Meituan’s financial report, Meituan’s overall performance in the third quarter was still quite good.

In addition to the financial data of Meituan’s various businesses mentioned earlier, let’s take a look at the performance of various business operations.

According to the financial report, Meituan’s annual active merchants reached 6.50 million, and the annual transaction users reached 480 million, showing a steady growth trend; this year, more than 4 million riders have achieved employment and income through the Meituan platform.

In addition, the average daily number of food and beverage takeaway transactions was 34.9 million, an increase of 30.1% year-on-year, and the average value of each food and beverage takeaway business order increased by 4.5% year-on-year.

Combined with the financial data, the transaction volume of food and beverage takeaway business was 152.20 billion yuan, an increase of 36.0% year-on-year; the revenue was 20.70 billion yuan, an increase of 32.8% year-on-year; the operating profit reached 768.5 million yuan.

Store, hotel and tourism revenue 65 billion yuan, an increase of 4.8%; operating profit 2.80 billion yuan, operating profit margin increased by 43.0%.

If we compare Meituan’s new business and old business data, we can see that Meituan has not given up its old business due to the development of new business.

In general, the total amount of resources is limited, and companies tend to allocate resources in a certain proportion. New business will receive more resources, while old business will have less resources to at least maintain the status quo.

That is to say, the underlying logic of this quota is to "explore new business and develop old business". There is nothing wrong with adopting this model for development. After all, new business often represents "unknown", and enterprises need to focus more on "exploration".

But for Meituan, Meituan’s business development is "exploring old business and developing new business".

The so-called exploring old business is actually constantly cultivating existing business with new ideas. After the epidemic, Meituan adopted a more accurate and high-quality marketing plan to upgrade in response to the arrival of the peak order season. This has increased the willingness of catering takeaway merchants to purchase traffic. Therefore, in the financial report, the platform’s third quarter takeaway online marketing service revenue increased by 60.1% year-on-year.

The essence of Meituan’s old business is actually to solve the problem of "food" for users. Like the emergence of takeaway services, it is convenient for users to eat what they want without leaving home.

Meituan did not stop on this basis, but instead asked users to upgrade to "eat better".

The core of this "helping everyone eat better and live better" is also based on the concept of consumption upgrading. Consumers’ dietary needs have become more abundant, and they must have more choices.

In the financial report, the order amount of food and beverage takeaway business increased by 4.5% in the third quarter, which shows that the platform brand merchants have improved; at the same time, the number of newly launched brand merchants in takeaway in the quarter increased by 157%, and consumers have more choices. In the third quarter, the booking business of Meituan Hotel also increased accordingly, and the high-star hotel cooperating with Meituan also increased significantly month-on-month.

At the same time, all kinds of "new tricks" have also been popularized and developed through the Meituan platform, such as escape room. Most merchants choose Meituan, Dianping and other platforms as their main way to acquire customers.

Meituan’s "development" of new business is actually an extension of old business, so it is called "development" of new business.

If "eating" is the core word of Meituan Company, then it can be said that all of Meituan’s business revolves around "eating".

Eat at home, Meituan takeaway; go out to eat, Meituan takes a taxi, Meituan bikes; want to play after eating, Meituan goes to the store…

Meituan’s new business is the same, which is based on the expansion of existing business. Meituan market and Meituan Preferred can be simply understood as the "shopping" service before users "eat".

Internet companies that adhere to "long-termism"

After understanding the underlying logic of Meituan’s business development, it is clear that Meituan is a company that adheres to "long-term doctrine".

Meituan has a clear development plan for what she wants to do and adheres to the long-term approach, which is the core concept of developing new businesses and exploring old ones.

And this development model also allows Meituan, as a platform-level company, to effectively promote the development of the industry. Especially when the entire industry encounters a crisis, such as the 2020 epidemic, Meituan can effectively help the market recover during and after the crisis, and solve the employment problem of a large number of riders.

In taking the "long-term" route, while fulfilling the various responsibilities and obligations of the company, the company needs to continuously invest resources. After all, firm goals are on the one hand, and to achieve goals, we must strive to explore value.

Some people say that Musk is a real-life version of Iron Man, and some people say that he is a Silicon Valley madman. But no matter what you call it, it reflects his bold and crazy business initiatives. Electric supercars, commercial rockets, satellites, solar roofs and underground high-speed trains, and even he will regularly sell flamethrowers… Many things that you can only see in science fiction movies, Musk is attacking everywhere. Especially on April 22, the media reported that the seventh batch of 60 "Starlink" satellites was launched, and the Falcon 9 rocket that carried out the launch mission was the fifth reused "five-handed" rocket.

Don’t be afraid to take September alone, and now Geely is also in the cloud? After Geely built a car with full wings, Li Shufu, who is nearly 60 years old, also began to think about "flying".

On April 26, a "rocket chief engineer" recruitment information from Geely Holding Group’s Time and Space Dao Yu Technology Co., Ltd., attracted great attention from the outside world: the job requirements column showed that the overall work plan of the rocket was looking for.

In fact, Geely wants to fly is not a recent thing.

"A car is just a few sofas and four wheels." This was Li Shufu’s "definition" of a car product twenty years ago. Perhaps in his opinion, a flying car should be able to take off with a pair of wings.

Geely acquired the world’s first flying car company, Terrafugia, in 2017. The company’s product is called Transition. From the perspective of appearance alone, it is more appropriate to call it a small folding-wing aircraft. According to official data, the power combination of the car (or the aircraft?) is a gas-electric hybrid system, which can take two people and can fly at a speed of 322 kilometers per hour in the air. The maximum flight altitude is about 3.048 kilometers, and the maximum endurance in the air can reach 800 kilometers.

However, it is now the end of April 2020, and the outside world has not seen any news of the mass production of this flying car. For this "science fiction" product, it may have been commonplace to skip the ticket. Even if the "flying car" does not arrive on time, Geely still wants to fly higher.

In this regard, Geely’s idea is to deploy low-orbit satellites to provide high-precision positioning services for high-level intelligent driving, in order to comprehensively enhance the user’s intelligent travel experience.

Of course, as people who eat melons, we don’t know if Geely’s satellites can successfully go to the sky within the year. However, from flying cars 3 kilometers in the sky to low-orbit satellites 200 to 2000 kilometers, in the popular words of the moment – Geely and Li Shufu’s goal is the sea of stars. Maybe in the future we will see Geely use its own "heavy rocket" to send its Geely sports car to the sky like Tesla.

If building a car can be highly summarized as "putting wheels on a sofa," then whether building rockets and satellites is to install rocket boosters on communication devices and send them to the sky? It’s definitely not that simple.

First of all, in terms of investment, the two are not on the same level at all.

Regarding the cost of building a car, relevant auto industry observers told Understanding Notes: "For general car companies, not counting those products that use the old platform to counterfeit products of other models, the cost of developing a new model is completely positive, which is about a few hundred million to one billion yuan. In addition, this cost will reduce the marginal cost with the increase of mass production of later models and the increase of" brother "models of the same platform."

Hundreds of millions to billions of yuan, which is already astronomical in the eyes of ordinary people, but when it comes to building rockets and launching satellites, it should not be enough.

According to Musk, "Starlink" will consist of at least 12,000 small satellites.

The technical prowess and billions of dollars spent to send such a large number of satellites into space are behind it. Because SpaceX is still not a publicly traded company, its financial data is not known to the outside world. But according to the company’s early estimates, the cost of building and launching satellites could be as high as $10 billion. From now on, the overall investment may only be much more.

The huge investment required behind "Heaven" is not unclear to Li Shufu, a veteran of the car industry. Under such circumstances, the reason why Geely still chooses the road of "Flying Heaven" is also very simple: the construction of the future intelligent travel network will not simply stay in the construction of the road network. In the highly integrated intelligent space, Geely’s low-orbit satellites will play a very important role.

In this regard, relevant auto industry observers told Understanding Notes: "First of all, Geely is doing this in the context of policies that are encouraging private capital to develop and launch commercial satellites; secondly, as Geely officials said – to a large extent, it is to prepare for high-level intelligent driving in the future." The person analyzed that mature autonomous driving requires the deep integration of high-precision navigation and high-speed communication networks, and the integration of communication is the development trend of the entire industry. "Geely has not only been tossing in the field of car manufacturing, but building an intelligent transportation ecosystem based on vehicle production is its ultimate appeal, so it needs to improve its own layout in the travel industry chain."

According to the "2018-2022 China Commercial Aerospace Industry Deep Research and Investment Prospect Forecast Report" released by CIC Consulting, the global aerospace industry is growing rapidly at a rate of 6% to 7% every year, and the size of our country’s aerospace market will reach 800 billion yuan in 2020.

Policy support, rapid market growth, strategic layout needs, from the perspective of strategic choice, Geely’s plan is logical. However, the wish is perfect if it can be realized, and the process of realizing the wish is "painful", especially at the current stage when Geely’s main business is under pressure.

We have heard the word cold winter in the car market countless times in the past year. Now affected by the pandemic, the market still sees no signs of recovery. In this situation, all car companies are under pressure, and Geely, a leading domestic car company, is also not feeling well.

According to the 2019 financial report released by Geely Automobile Holdings Co., Ltd., Geely Automobile sold 1.3616 million vehicles (including Lynk & Co) last year, and 1.5008 million vehicles in 2018, down 9% year-on-year; total revenue in 2019 was 97.71 billion yuan, down 8.6% year-on-year, and net profit was 8.19 billion yuan, down 35% year-on-year.

In addition, in the field of new energy vehicles, which has received the most attention, although Geely has been very aggressive, it has not achieved the expected effect. As early as 2018, when the "Blue Geely Action" was released, Li Shufu said, "By 2020, more than 90% of Geely cars will be new energy vehicles."

"Geely is indeed very determined to turn to new energy, but from the perspective of product strength, Geely’s new energy series is obviously not the best (but not bad), and the reason why it does not perform better in the field of new energy than domestic competitors such as BYD and BAIC is that Geely has to take into account its own basic market." A senior industry insider told Zhonghe Notes that although new energy vehicles are very popular, in recent years the market is still dominated by fuel vehicles, "so at least for now, fuel vehicles are still Geely’s guarantee, so it will not be as aggressive as BYD and BAIC."

The current downturn in the domestic auto market is due to the fact that the entire auto market is caught in the dilemma of slowing demand, but this also highlights that, despite being a leading domestic car brand, Geely is still unable to escape the impact of the industry cycle in the competition in the stock market.

No one can anticipate when the recovery of the car market will occur. Investing heavily in "heaven" under such circumstances is definitely a pressure for Geely. Regarding Geely’s choice, relevant auto industry observers pointed out: "To achieve the integration of communication and navigation, it is definitely not enough to be close to two satellites. The entire intelligent travel network needs at least dozens of satellites to basically cover, which will be a long process."

Geely seems to be thinking further than BAIC and BYD to take a step ahead of its competitors. But at the same time, it is also very clear that selling cars is its basic game. As for the rocket chief and "God", Geely can’t be in a hurry.

The love story about Wang Sicong is not the first time I have heard about Wang Sicong’s love story, but as changeable, suspicious, suspicious, and suspicious as this time chasing Sun Yining.

The causes of this matter have been summarized as follows:

In April, Wang Sicong watched Sun Yining’s appearance on the short video app to brush gifts, hundreds of thousands of gifts, and recognized Sun Yining as the ancient Internet celebrity "Pig Girl" who cheated money and returned to the Internet four years ago;

On June 15, Sun Yining cried and made a scene in the camera room, so that Wang Sicong didn’t have to force her.

Wang Sicong responded that Sun Yining lied to him and wanted to find a WeChat official account to break the news;

Sun Yining preemptively published the SIMP classic quotations of Wang Sicong’s overbearing inducement;

Wang Sicong broke the news that Sun Yining Lala, set up fake CP, and ate Ji Circle.

After the incident, Wang Sicong’s oily and tender words on Weibo became popular, and after the "principal" and the "entertainment industry discipline inspection committee", he was named a "think tank".

Kindness netizens also combed Wang Sicong’s classic quotes, and for a while, everyone also scrambled to use smart oils to make sentences, which can be described as the participation of the whole people.

Some people say that Wang Sicong is the king of classic words, and every sentence he often says can be applied to all scenes;

The other faction fully supported Sun Yining, feeling that this beautiful lady was nasty and wanted to be her fan.

Behind this question was undoubtedly the sarcasm of netizens that Wang Sicong wanted love and property bankruptcy this time. After all, Wang Sicong, who used to be known as the husband of the whole people, had chatted with many beautiful girls.

His father is Wanda Wang Jianlin, the boss of Evergrande Group. The company involves the real estate industry, business, catering industry, culture and entertainment and other industrial chains. Basically, it includes everyone’s daily life "eating and walking", and it must be included in the rich list.

The stable second generation of rich needless to say, he also likes to make trouble. Start-up company opened a lot of companies. Price’s earliest investment was that his father gave him 500 million assets to exercise his work ability. Later, several projects invested in companies in a variety of industries including mobile games, social media, electronic sports and restaurants. Subsequently, Panda Interactive Entertainment was established, which opened its entertainment industry chain, most notably the Banana Project.

There are many merchants, needless to say, luxury cars are easy to take out, all at the level of several suites.

The company is valued at $10 million to build the Rolls-Royce Magic;

More than six million dollars worth of Ferraris.

The world is limited to 918, more than 40 million, all of which are in Wang Sicong’s bag. Of course, this is just an iceberg in his garage.

Not to mention the real estate, he bought not a 136-square-meter bungalow, but a 156-square-meter high-priced house. In an interview with the BBC, he also revealed that the hotel restaurant he rented was all 8,000 luxury suites for one night, or was it a long-term stay?!

The daily life of the wealthy is beyond the imagination of ordinary people.

At the age of 27, Wang Sicong’s net worth has reached 6.30 billion, from his father’s five hundred million to 6.30 billion, he has to admit that he or a little business sense, in the project investment also has a certain vision.

And it is precisely because of the characteristics of the enterprise he established: the appearance of signing a contract to develop Internet celebrity trends occupies a large trend, so Wang Sicong also has several popular ex-girlfriends.

People in the city all say "falling Sicong, mobile Internet celebrities", and the names removed leave no more than 10 photos of the tryst.

Wang Sicong’s first love, Zhang Qian, who was hard to let go of, may have allowed him to take great strides…

Wang Ying was a beautiful female model, but this girlfriend had exposed too much of her past, and Wang Sicong had also ended his maintenance of beauty. The intimate name "Wang Xiaobeng" was also pure, but after hearing that Wang Sicong might feel cheated, he began to change clothes with his girlfriend.

Later Internet celebrity Song Liang, Zheng Kai also had a period of biography, can be regarded as one of the Internet celebrities.

Then came to the artist Zhang Yuxi, who had already successfully transformed and developed;

Zhao Ziyi, the woman behind Wang Sicong’s pet dog Wang Keke’s success;

Go to the famous Internet celebrities Pear and Doudell.

These can be regarded as the ex-girlfriends of Wang Sicong who are familiar to the partners, and those Internet celebrities who are likely to be infamous for a while are not a problem.

Therefore, what everyone never expected was that Wang Sicong, who was so adept at falling in love, would also have the day when the car overturned, and returned a lot of hilarious jokes that everyone had given after dinner.

But after careful observation, Wang Sicong didn’t seem to be happy with the road of love. This wasn’t the first time. It seemed that after eating the hardships of love, the actual operation of Sun Yining’s SIMP circulatory system was also very similar to the big brother in daily life.

　　A few days ago, Guangxi University of Foreign Languages issued the "Notice on Not Allowing Disposable Tableware and Lunch Boxes to Enter the Campus", which caused a heated discussion on the Internet. The notice said that starting from November this year, in order to strengthen the food safety management of students, the school will ban takeaway, disposable lunch boxes and plastic bags from entering the dormitory.

　　As soon as the notice was released, it immediately triggered a heated discussion on the Internet, and there were many different voices on campus. Some students believed that the school cafeteria had problems such as crowded space and long waiting time for meals, which could not meet normal dining needs. Prohibiting takeout and packing boxes into the dormitory would bring inconvenience to study and life. Some students said that everyone was used to ordering takeout, and it was difficult for the school to control it.

　　The school said in a statement released later that the move was mainly due to considerations such as environmental protection, food safety and school teaching order. The food safety of takeaway food is not under the supervision of the school, and some food that does not meet the hygiene standards flows into the school with takeaway food, posing a threat to the health of students. At the same time, small vendors carry takeaway food in and out of the campus at any time, which not only affects the teaching order of the school, but also is not conducive to the establishment of a good school ethos.

　　It is understood that in recent years, campus food delivery has developed rapidly, and various conveniences and preferential conditions have attracted a large number of students. At the same time, there are also many hidden dangers in the delivery of food into the campus. School administrators are very troubled by the news that students have food poisoning after eating food delivery and the theft of food delivery staff.

　　In fact, before Guangxi Institute of Foreign Languages issued the notice, some institutions such as Jiangxi Nanchang Institute of Technology had already issued relevant regulations on the management of takeaway food, and everyone had mixed opinions on this move. How to standardize the management of takeaway food into the campus and balance the interests of all parties still needs to be explored.

　　■ Collision

　　Blindly prohibiting will be more "blocking"

　　I have been ordering takeout for lunch and dinner since I was an undergraduate. At that time, the takeout industry was highly competitive and there were many discounts, which could satisfy our demand for delicious food at lower prices. Now suddenly banning takeout from campus is "adding to the blockage" of students. What’s more, as long as the convenience that takeout brings to students still exists, it is difficult to ban it. If it is violently stopped, the merchant may continue to operate in a covert way, so the potential hidden dangers are still difficult to eliminate, but it increases the difficulty of management.

　　2017 graduate student of Guangxi University of Arts, Wang Hengyu

　　Campus ban on takeout is legally binding

　　From a legal point of view, universities and some private communities have the right to establish some rules and regulations to prohibit outsiders and food from entering their management scope, which does not restrict the freedom of students and residents. Especially when it comes to food safety, environmental protection and other matters related to personal and property safety, relevant schools and communities have the right to take necessary measures to protect them. Schools have the responsibility to ensure the safety of their personal and property for students in school. If they agree to food safety items entering the campus, and students have accidents on campus, then the school will be legally responsible for certain mismanagement. Therefore, there is a certain reason why the school does not allow takeaway into the campus.

　　Pang Caiyou, Director of Beijing Shangheng (Nanning) Law Firm

　　The takeout chaos should have been controlled long ago

　　As a parent, I support the school’s regulation of takeaway food. Parents are worried not only about safety, but also about the health of their children. Many takeaway foods are not guaranteed to be healthy even if they are safe. Due to cost considerations, the quality of the ingredients selected by some merchants cannot be guaranteed, which will affect physical health. Moreover, children’s studies are not so stressful that they don’t have time to eat. Most of them want to be lazy. From a certain perspective, takeaway helps children develop bad habits. The takeaway chaos should have been controlled long ago!

　　Ms. Wang, Parent of University of Science and Technology of China Class of 2017

　　The school should not ban it

　　I have seen a lot of "complain" about college cafeterias on the Internet, and I have experienced it myself, such as the food is unpalatable, expensive, and unhygienic. In my opinion, it is inappropriate and unacceptable for schools to adopt a "one-size-fits-all" management method to ban takeout from entering campuses. If schools really start from the perspective of students, solving the campus safety problems caused by takeout should start from two aspects: improving the quality of cafeterias and standardizing the management of takeout personnel entering campuses.

　　Wang Jian, a citizen of Changsha, Hunan

　　Campus ban on takeout is understandable

　　From the perspective of campus management, it is understandable to ban takeout and packaging boxes from entering the campus. Some institutions have formulated this regulation to strengthen food safety management. At the same time, from the perspective of campus-wide environmental hygiene management, it is necessary to ban takeout. Schools, as the responsible person for the safety of students’ lives and property, are responsible for the personal safety of students during school. It is understandable to take measures to eliminate hidden dangers before finding more effective management methods.

"hanging wire for pulse diagnosis" of satellites in orbit

■ Lu Binghong Zhang Mi Liberation Army Daily reporter Wang Lingshuo

On the eve of the Spring Festival this year, Xi ‘an Satellite TT&C Center successfully completed the health status assessment of 52 Beidou navigation satellites. Through the "physical examination" of the Beidou navigation satellites in orbit, the scientific and technical personnel ensure that the key technical indicators of these satellites meet the requirements of providing various services normally and continue to maintain good working conditions in orbit.

The reason for the "physical examination" of satellites is that satellites in the past days will sometimes have "minor ailments and pains" or even "incurable diseases", which will affect business applications and lead to the failure of the whole satellite. China’s space science and technology workers are deeply involved in the on-orbit diagnosis and maintenance technology of spacecraft to realize early detection, prevention, diagnosis and treatment of satellite faults.

Schematic diagram of injecting maintenance instructions on the ground to satellites in orbit

Satellites in orbit are so delicate.

When it comes to space flight, people often think of the rocket launch that attracts people’s attention and rises in flames. In fact, this is only the prelude to the space mission, and the work really begins when the satellite enters the scheduled orbit and is put into business application in space.

Satellites are the largest number of spacecraft launched by human beings, accounting for more than 90% of the total number of spacecraft launched, and have considerable uses in meteorological monitoring, communication and navigation, disaster prevention and mitigation and other fields. As a complex system composed of thousands of components, satellite has more and more functions and greater value with the continuous development of technology. The times of detection, diagnosis, calculation and treatment, control and disposal, and the telemetry parameters that need to be downloaded and monitored are also increasing. This puts forward higher requirements for the accuracy and stability of the ground control system. However, satellite technology is complex and dense, and it is in a complex space environment, so the probability of failure exists objectively and there are various types.

In 2018, shortly after the latest model of meteorological satellite GOES-17 in the United States was put into orbit, the cooling system failed, which made the imaging system of this satellite unable to provide satellite images in near infrared and infrared channels. Satellites can’t get infrared cloud pictures taken at night in time and effectively, and they become "blind" at night.

Coincidentally. In July, 2019, the European Galileo satellite navigation system lost all 24 satellites due to the timing error of the precise timing facilities located in Italy, and the whole system was once paralyzed. It was not until a week later that the system fully resumed service.

At the same time, satellites operate in a vacuum, weightlessness, ultra-low temperature, strong radiation and full of unknown factors for a long time, and space junk and solar activities will bring trouble and even fatal damage to satellites. Therefore, it is inevitable that there will be some technical problems during the life of the satellite.

What’s more, the cost of modern satellites is high, and with the launch cost, the cost of a satellite is often calculated in hundreds of millions of yuan. If the technical failure of the satellite is not eliminated in time or cannot be eliminated, huge economic losses will be inevitable. Therefore, once the running satellite fails, all countries will spare no effort to rescue the satellite and minimize the loss.

Troubleshooting with "Hanging Wire Pulse Diagnosis"

When there is a problem with the machine on the ground, people can locate and eliminate the fault through various methods. For satellites in orbit, it is the only way for technicians to master the attitude and working state of satellites by means of electromagnetic wave transmission.

The so-called satellite fault diagnosis and maintenance means that when the satellite fails, in order to avoid the paralysis or functional failure of the whole system caused by the failure of some components, the state detection, fault diagnosis, health assessment and other work are carried out quickly through telemetry data, the current state and future "illness" trend of the satellite are analyzed, the satellite fault level is defined, the fault location and cause are determined, and the treatment is carried out in time. This is just like the plot of "hanging the wire to feel the pulse" in Chinese classical novels and traditional operas. With this core technology, ground measurement and control personnel can detect tiny faults hidden inside the satellite as soon as possible, and after fault identification and fault isolation, take corresponding maintenance support or fault degradation treatment, so as to avoid catastrophic failures of the satellite and ensure the safe operation of the satellite.

The diagnosis and maintenance technology of spacecraft is developed with the realistic requirements of spacecraft mission expansion, control accuracy improvement and working life extension. The traditional space powers, represented by the United States and Russia, started earlier and have done a lot of research and practice in this field.

In the 1960s, with mankind gradually entering the space age, the spacecraft diagnosis and maintenance technology was also launched. Due to the limitation of technical conditions, component quality and design level at that time, people can only rely on simple instruments to monitor some key parameters of the satellite with single signal threshold state in this period to judge whether there is a fault. This method provides a certain guarantee for the on-orbit operation of early human spacecraft. At this stage, the average life of spacecraft is generally short. In manned space mission, the safety guarantee system of the system is composed of state monitoring, ground expert consultation and astronauts’ direct participation, and the autonomy, real-time and reliability of the spacecraft fault detection system are also poor.

Since 1970s, with the development of technology and the improvement of component quality, design level and process level, the diagnosis and maintenance technology based on hardware redundancy has been widely used in the field of spacecraft. The diagnosis method has also developed from simple threshold judgment to making full use of various dynamic testing technologies, monitoring technologies and information processing technologies, which has greatly extended the average life of spacecraft.

During the Apollo mission to the moon, the United States first established a flight anomaly analysis and evaluation system. The system includes flight fault monitoring and processing, flight state evaluation, flight data standardization, fault ground simulation, etc., and all emergency life-saving parameters are equipped with triple repetitive sensors and dominant voting logic circuits, which obviously enhances the autonomy and reliability of the spacecraft fault detection system.

In the 1980s, artificial intelligence research flourished, and knowledge-based diagnosis and maintenance technology, especially expert system technology, began to be widely used in the aerospace field. Among them, several intelligent fault diagnosis technologies based on expert system and testability model data-driven are the most representative. At the same time, the appearance of highly complex and reusable spacecraft such as the space shuttle makes the fault diagnosis and maintenance system not only have the distribution of modular functions, but also have the integrity of coordination. With the gradual construction and on-orbit operation of the International Space Station, its fault diagnosis and maintenance system has further greater variability, better adaptability and stronger robustness, and gradually develops in the direction of self-management, so that the failed space station can continue to complete its scheduled tasks without affecting its performance.

"Star Shepherd" guards "China Star"

The management level of long-term in-orbit satellites largely determines the realization of satellite efficiency. Since China launched the first artificial earth satellite in 1970s, the spacecraft on-orbit management and control technology has made great progress through the unremitting efforts of several generations of scientific and technological personnel.

As early as 2007, relying on Xi ‘an Satellite Monitoring and Control Center, China began to build a national-level "satellite general hospital"-spacecraft on-orbit diagnosis and maintenance center, and immediately carried out major scientific research projects in the field of spacecraft on-orbit fault diagnosis and maintenance.

With the increasing number of satellites in orbit, China urgently needs to further improve its on-orbit diagnosis and maintenance capabilities. In 2014, Xi ‘an Satellite TT&C Center established China’s first on-orbit fault diagnosis and maintenance laboratory. Through the research on early identification and location technology, on-orbit fault simulation and maintenance technology, on-orbit reliability growth and life extension technology, the independent innovation ability of on-orbit fault diagnosis and maintenance of spacecraft in China was further improved, which promoted the sustainable development of China’s aerospace engineering and became a solid foundation support for the continuous increase of the number of on-orbit satellites in China.

By collecting and sorting out thousands of fault cases at home and abroad and summarizing nearly one million pieces of diagnosis knowledge, the center independently developed an expert system for spacecraft fault diagnosis, which effectively solved the problems of late discovery, slow analysis and difficult positioning of spacecraft micro-faults.

In addition, starting from Beidou satellite, they independently developed a satellite health assessment system, established a relatively complete three-level health assessment index system of "sub-system, key single machine and key performance", put forward a meta-knowledge construction method of health assessment for single satellite in orbit, and built a detailed "physical examination file" for each satellite. The evaluation conclusions of the satellite system put forward targeted countermeasures and suggestions for the follow-up satellite on-orbit management from the aspects of key components’ operation state, abnormal prevention and response, space environment change and load efficiency guarantee, which effectively ensured the safe and stable operation of Beidou system in orbit.

As the largest long-term management center of spacecraft in China, Xi ‘an Satellite TT&C Center has been managing China’s satellites in orbit for a long time, taking on the on-orbit management tasks such as daily telemetry monitoring, orbit control, fault diagnosis and maintenance, and it is a veritable "big housekeeper" of China satellites. Although the "China Stars" are in space, they are not alone, but are always under the care of the "Star Shepherd".

In the future, Xi ‘an Satellite TT&C Center will also deeply and extensively apply artificial intelligence technology, comprehensively improve the level of diagnostic and maintenance capabilities, and lay a solid technical foundation for the on-orbit management of the "giant constellation" in the future.

　　Li Laijin is on his way to deliver takeout.

　　This summer, the number of takeaway orders in Beijing at night has increased by 60% compared with last year. According to data, Changping Huojiaying and Fengtai Minute Temple ranked first and second in the ranking of the most active business districts at night. In addition, in Yanqing District and Huairou District, the number of late-night barbecue orders increased by more than 4 times year-on-year. Behind the surge in the number of orders is every "on-time delivery" of the takeaway brothers. From 9:00 pm to 12:00 pm is the peak period of night takeaway orders. They shuttle through the streets and alleys, adding "dynamic beauty" to the night Beijing.

　　Delivery riders haunt at night "with additional subsidies and no one grabs orders"

　　"Ding Ding", at 10:59 pm, Li Laijin, who was born in 1996, received a new order.

　　From the "7-11" convenience store on Xierqi West Road to the "Contemporary City Home" community about 1.2 kilometers away, the system recommends that riders be delivered within 28 minutes.

　　"Hello sir, sorry for the long wait." After 20 minutes, Li Laijin completed the delivery, which was 8 minutes faster than the time suggested by the system. He just pressed the button to confirm "delivery completed", and the "ding ding" sounded, and the new order came again. Between 9:00 and 12:00 that night, Li Laijin sent out a total of 6 orders.

　　According to data from a takeaway platform, the number of late-night takeout riders born in the 1990s has increased by more than 60% compared with last year. Li Laijin is one of them. The site where Li Laijin works is located in Zhongguancun Software Park. During the day, orders are mostly concentrated in Internet companies, and most of the night orders come from residential areas near Huilongguan.

　　Gu Xiaofang, a 32-year-old female rider at the Wangjing shopping district, also likes to work at night. Gu Xiaofang’s site is divided into three groups. Her group has more than 30 people, and there are six or seven people who work night shifts every day.

　　"There are subsidies, there are few riders, and no one grabs orders at night." This is the main reason why Li Laijin and Gu Xiaofang like to work at night. According to Li Laijin, at the software park distribution station, the courier earns 10 yuan for delivering an order during the day, and there is a subsidy of 2 yuan for each order at night. At Wangjing Station, where Gu Xiaofang is located, in addition to the subsidy for each order, he can get an additional 20 yuan per night. In Gu Xiaofang’s view, the evening is the third time with higher income after the two dining peaks at noon and evening.

　　Mr. Jia, a 31-year-old father of two, runs more night shifts than other riders at the station. "If you run a dozen or so, you can earn 20 yuan more," Mr. Jia said. "I take the initiative to work the night shift until 12 o’clock every day."

　　According to reports, this year, Jia Shaoke has completed a total of 7,923 orders, with an average of 34 orders per day. The rider level has reached Gold 1, and the next promotion level is the most advanced king.

　　Order remarks are varied "Delivery of takeout and handwritten sweet words"

　　Many people like to write notes when ordering. Statistics from a takeaway platform show that from the beginning of 2019 to August 5, among late-night orders between 9 pm and 5 am, riders received more than 560,000 notes asking to buy cigarettes on their behalf. The request to throw garbage on their behalf ranked second, with 9,397; the third order note was somewhat unexpected, asking riders to "draw a picture". In addition, the number of messages asking riders to play games, dance, and tell jokes followed closely, with 4,595, 966, and 722, respectively.

　　Among the orders received by Li Laijin and Gu Xiaofang, buying cigarettes and snacks on behalf of others is the most common. Li Laijin said that he once visited five convenience stores to help customers buy "Yoyo Mei". He also added WeChat with customers to determine the brand type through video communication.

　　What impressed Li Laijin the most was that he once copied more than 100 words of "sweet words" for a customer and sent it with the takeaway. As for the customer’s note request, Gu Xiaofang said, "The company does not have a clear rule that must be met, but we can help with everything we can, and it is easy to do."

　　There is no shortcut to more work and more "I want to be the webmaster of the takeaway station in the future"

　　When it comes to the difficulty of delivering food, it has to be said that traveling in bad weather, about which the riders "love and hate".

　　Delivered in bad weather at night, an order can earn about 13 yuan, which is 30% higher than the usual day. And when it comes to windy and rainy weather, takeaway orders also increase.

　　Li Laijin recalled that there was a drizzle that night on August 20, and he delivered 11 orders within two and a half hours, nearly double the number of orders from the previous day.

　　After the early morning, the order interval was relatively long, and the riders began to gather together to chat. Whether the new number of kilometers ran broke the record, and whoever rose to a new high on the rider’s single king list could make them chat in full swing.

　　Due to the long-term exposure to the sun, Li Laijin’s skin was dark, in sharp contrast to his original skin tone. "The wind and the sun are a little old, but I’m still young." Li Laijin quipped.

　　Li Laijin became a delivery rider two years ago. In his opinion, this industry is more work and more money. You can earn as much money as you run as many orders, and there are no other shortcuts. "You can get as much as you do in this industry." He likes this. "As long as I have orders, I can work harder and harder, and I am not afraid to stay up late." Li Laijin said he will continue to work in this industry. "I want to be a delivery station manager in the future."

　　As soon as Li Laijin finished speaking, a "ding ding ding" prompted him: "You have a new takeaway order, please deal with it in time". Then, he quickly got on the electric car and drove into the night. Text/This reporter, Zhu Jianyong, trainee reporter, Han Qian, intern, Zhang Yujie, Zhu Yadi
