How to buy a blank house that meets the demand? What factors affect this purchase decision?

In the real estate market, blank houses attract many buyers with their unique charm. It gives buyers more independent space to build their ideal homes, but it is not easy to buy a blank house that meets their own needs, and the purchase decision will be affected by many factors.

First of all, being clear about your own needs is the key. In terms of housing demand, if the family population is large, it is necessary to consider large-sized units to ensure that every family member has enough living space; For singles or newlyweds, a small apartment may be more suitable, which can not only meet the living needs, but also reduce the cost of buying a house. The purchase budget also plays a decisive role, which directly limits the range of available houses. If the budget is limited, we need to pay attention to some areas or buildings with relatively low prices; If the budget is sufficient, there can be more high-quality houses to choose from.

Location and supporting facilities are also factors that cannot be ignored. A rough house with a good location often has higher appreciation potential and living convenience. The convenience of surrounding traffic is very important. Being close to subway stations, bus stations or main roads can greatly shorten commuting time. Commercial facilities also affect the convenience of daily life. There are large shopping malls, supermarkets and vegetable markets nearby, which can meet various life needs such as shopping and catering. Educational resources are also the focus of many property buyers, especially families with children. Quality schools can provide a good educational environment for children. Medical support is equally important, so that you can get medical treatment in time when you are sick.

The quality of real estate and the reputation of developers also have great influence on the purchase decision. Housing quality is the foundation of living, and high-quality building quality can ensure the safety and comfort of living. You can understand the quality of the house by looking at the building materials, construction technology and word-of-mouth of past projects. The reputation of developers is also very critical. Developers with good reputation usually pay more attention to project quality and after-sales service, which can make buyers feel more at ease.

In order to compare the influence of different factors on the purchase decision more clearly, the following is a simple table:

influencing factor Importance statement Self-demand Defining the housing demand and budget is the basis of screening housing. Lot and supporting facilities Affect the convenience of living and the appreciation potential of houses. Property quality and developer’s reputation It is related to residential safety and follow-up service guarantee.

Market conditions, policies and regulations will also affect the purchase decision. When the real estate market is on the rise, it may be necessary to make a purchase decision as soon as possible to prevent the house price from continuing to rise; In the downturn of the market, you can have more time and choice space. Changes in policies and regulations will also have a major impact on the purchase of houses, such as restrictions on purchases and loans, which will directly affect the purchase qualifications and loan quotas of buyers.

When buying a blank house, you need to conduct a field trip. Check the apartment structure of the house on the spot, understand the lighting and ventilation of each room, and feel whether the spatial layout of the house is reasonable. At the same time, it is necessary to check the quality of the house to see whether the wall is flat, whether there are cracks, and whether the ground is level.

Buying a blank house that meets the demand requires comprehensive consideration of many factors. Property buyers should be clear about their own needs, pay attention to lots and facilities, attach importance to the quality of real estate and the reputation of developers, understand market conditions, policies and regulations, and conduct on-the-spot investigations, so as to make wise purchase decisions.

Tax big data takes you through the economic situation in the first quarter.

  Xinhua News Agency, Beijing, April 23rd  Title: Tax big data, take you through the economic situation in the first quarter.

  Xinhua News Agency reporter Wang Yuxiao

  In the first spring of the 14th Five-Year Plan, China’s economy made a steady start.

  How is the production and operation of the enterprise this spring? What is the recovery geometry of the consumer market? How to judge the foreign trade trend? State Taxation Administration of The People’s Republic of China released a set of tax data on the 23rd, highlighting the good trend of China’s economy in the first quarter.

  There are more than 2.7 million new tax-related market entities.

  Market subject is the foundation of economic development. According to State Taxation Administration of The People’s Republic of China data, in the first quarter, there were 2.792 million new tax-related market entities in China, up 86% year-on-year, up 34.9% compared with the same period in 2019, with an average growth of 16.1% in two years.

  Since the beginning of this year, the tax authorities have implemented the working mechanism through the "one pole to the end" policy, implemented the preferential policies for reducing taxes and fees, vigorously promoted high-quality and efficient intelligent tax and fee services, and helped enterprises to "travel light".

  According to the data of VAT invoice, in the first quarter, the sales revenue of national enterprises increased by 50.5% year-on-year, with an average growth of 12.8% in two years, which continued the steady and good growth trend since the second half of last year.

  Looking at the Development of Manufacturing Industry from VAT Invoice Data

  Manufacturing is an important foundation of the real economy. According to the data of VAT invoices, in the first quarter, the sales revenue of the national manufacturing industry increased by 49.7% year-on-year, 20.2% higher than that of the same period in 2019, with an average growth of 9.6% in two years.

  The rapid development of manufacturing industry has effectively stimulated the accelerated recovery of industry. The data shows that in the first quarter, the sales revenue of industrial enterprises nationwide increased by 46.7% year-on-year, with an average increase of 9.3% in two years.

  With the effective implementation of various tax policies to support scientific and technological innovation, the scientific and technological innovation ability of enterprises has been continuously enhanced. According to the data of VAT invoice, in the first quarter, the sales revenue of China’s high-tech industries increased by 53% year-on-year, with an average increase of 19% in two years, faster than the national average.

  In addition, the sales revenue of civil engineering construction industry in the first quarter increased by 44.8% year-on-year, with an average growth of 15.8% in two years, continuing the rapid growth trend since the fourth quarter of last year; The sales revenue of agricultural machinery products increased by 78.7% year-on-year, with an average increase of 40% in two years.

  Retail sales revenue increased by an average of 13.4% in two years.

  From the central government to the local government, the implementation of a series of preferential tax policies to promote consumption and expand domestic demand has effectively boosted residents’ consumption confidence.

  According to the data of VAT invoice, in the first quarter, the national retail sales revenue increased by 52.9% year-on-year, with an average increase of 13.4% in two years. Some upgraded consumption increased significantly, and the sales revenue of jewelry, watches and clocks, health care and medical equipment increased by 75.4%, 88.6% and 73.2% respectively.

  Since the outbreak, online education, Internet diagnosis and treatment and other new formats and new models have become new kinetic energy to activate consumption potential. In the first quarter, the sales revenue of digital cultural services and residential Internet services increased by 60.3% and 65.4% respectively year-on-year, and continued to maintain rapid growth from last year’s high base.

  The domestic purchase amount of export enterprises increased by an average of 16% in two years.

  The high-quality development of foreign trade is an important driving force for economic growth. In recent years, the tax authorities have actively implemented export tax rebate facilitation measures, simplified the tax rebate process, compressed the time limit for tax rebate processing, and effectively eased the pressure on enterprises to occupy funds.

  In the first quarter, the recovery of overseas demand continued to drive the rapid growth of China’s exports, and the domestic purchase amount of export enterprises nationwide increased by 46.5% year-on-year, with an average increase of 16% in two years. From the perspective of export industries, export enterprises such as electrical machinery and equipment and special equipment have strong purchasing intentions, and the purchase amount has increased by over 50% year-on-year, and the expectation of expanding production in related industries has increased.

  Investment in environmental protection equipment of enterprises has increased.

  In recent years, the tax authorities have played the role of tax leverage to encourage enterprises to increase investment in environmental protection and transform to green and low carbon. According to the data of VAT invoice, in the first quarter, enterprises increased their investment in environmental protection equipment, and the procurement of pollution prevention equipment and environmental monitoring instruments increased by 63.5% and 54.9% respectively, with an average increase of 12.7% and 11.7% respectively in two years.

  Various preferential tax and fee policies to support the development of new infrastructure industries have effectively promoted the gradual optimization of investment structure. According to the data of VAT invoice, in the first quarter, the amount of communication access, mobile communication and communication transmission equipment purchased by enterprises increased by 78%, 72.9% and 46.7% respectively, with an average increase of 10.3%, 15.8% and 10.6% respectively in two years.

  Zhao Lianwei, deputy director of the Income Planning and Accounting Department of State Taxation Administration of The People’s Republic of China, said that the growth rate of various indicators in the first quarter was relatively high. First, due to the effectiveness of China’s overall epidemic prevention and control and economic and social development, a series of policy effects were continuously released, and domestic and international market demand picked up; Second, affected by the epidemic last year, the base of various indicators was low, which led to a higher increase in indicators in the first quarter of this year.

  "To read the economic situation in the first quarter correctly, we should not only look at the year-on-year growth, but also look at the growth compared with the same period in 2019. Calculating the two-year average growth rate can reflect the economic operation situation more objectively and comprehensively." Zhao Lianwei said that the tax system will actively explore the use of big data, carry out multi-level tax economic analysis, serve market players and macro-decisions, and make new and greater contributions to building a socialist modern country in an all-round way.

Meet the ice and snow, come together | What kind of romance will you see when Winter Olympics meets the Spring Festival?

Dongao Village will officially open on January 27th. This time, the athletes and related personnel who come to participate in the Olympic Games will cross the winter and spring here.

CCTV News:"Isn’t it a pleasure to have friends coming from afar?" Fourteen years ago, in the summer, the eyes of the world focused on Beijing, and China stood the test, showing its due demeanor as a big country, so that all the people who came to China to participate in the Olympic Games felt the enthusiasm and demeanor of a country of etiquette. Four years ago, at the closing ceremony of PyeongChang Winter Olympics, in the stunning "Eight Minutes in Beijing", the Chairman of the Supreme Leader sent an invitation via video: "I and hundreds of millions of people in China welcome friends from all over the world and meet in Beijing in 2022! Welcome you, welcome friends! " The opening ceremony of the Beijing Winter Olympics is approaching. As the only "Double Olympic City" in the world, Beijing is ready again to welcome guests from all directions. CCTV News+uses a set of posters to show you the "invitation letter" of Beijing Winter Olympics, and to show you the cultural and visual feast.

China’s feelings are not divided into hot summer and cold winter

The Olympic Village of the 2008 Beijing Olympic Games was officially opened on July 27th, which made the whole world see the capital in the midsummer season, and also made the guests feel the fiery enthusiasm of the people of China. In the Olympic Games, the athletes went all out and fought bravely for the first place. Outside the Olympic Games, the guests from all over the world were objective, and the birds were singing and insects were singing. This year, the Olympic spirit was closely combined with Chinese excellent traditional culture for the first time.

In the 2022 Beijing Winter Olympics, the "Opening Village" day of the Winter Olympic Village was chosen on the 27th. It is understood that the closed-loop management during the Winter Olympic Games and the trial operation of the Winter Olympic Village were officially opened on January 23, which means that athletes from all countries (regions) will enter the village one after another.

The Beijing Winter Olympics will officially open in the Bird’s Nest on February 4th, which coincides with the fourth day of the Lunar New Year and the beginning of spring in the 24 solar terms, all of which embody "Chinese romance". On the big stage of the Winter Olympics, the integration of China elements explains our cultural self-confidence. At that time, the world will once again witness the combination of the Olympic spirit and China elements.

The four seasons flow, and this friendship remains unchanged.

"I am eager to talk about it, and I am happy." Athletes are rivals who respect each other on the field, and friends who live in harmony off the field, while Dongao Village is a "warm home" for athletes during the games.

The Olympic Village is the most important non-competitive venue area of the Olympic Games, and it is also a microcosm of the host’s hospitality. During the Winter Olympics, the Winter Olympic Village is expected to receive delegations from 54 countries and regions and 1,670 officials who mobilized and accompanied the Winter Olympics. It will provide them with 24-hour high-quality accommodation, medical care, business and other services.

The design of the Winter Olympic Village is also very particular. It is understood that its overall design concept comes from Beijing Siheyuan, and the entrance gate and building facade are made of grids and bucket arches refined from traditional buildings in China. The apartment is divided into four units, and the whole room is clean and tidy. The combination of azure headboard, white walls, warm curtains, light-colored composite wood floors and dark furniture makes the interior of the apartment look warm and elegant.

In addition, there are functional spaces such as delegation offices and small conference rooms in the Winter Olympic Village, and barrier-free facilities are set up in toilets and stairs. The buttons and sockets of apartment buildings opened for the Winter Paralympics are all low-level designs. Panic button is located in a conspicuous place above the bedside table. In case of emergency, you can call with one button, and the information goes directly to the central control room … … The Beijing Winter Olympics will show humanistic care to the fullest in the subtle details.

Beijing and the Olympic Games met in the midsummer of 2008 and the winter of 2022. "All the guests come from all directions". No matter the seasons change and the years change, no matter what challenges and difficulties we face, we will show this unchanging friendship and care.

As the Beijing Winter Olympics is about to open, Chinese is fulfilling its responsibilities as the host in different ways, so that the "Double Olympic City" and the oriental ceremony will once again shine in the world.

AI native application, why difficult to produce?

 Picture | |Bohdan Kit

Quadrant originality

Wen Yi Luo Ji

Programming heart

The native application of AI is "difficult to produce".

After the Hundred Models War, a group of exhausted entrepreneurs gradually reacted: the real opportunity for China lies in the application layer, and the native application of AI is the most fertile soil for the next round.

▲ The picture comes from the Internet.

Robin Li, Wang Xiaochuan, Zhou Hongyi and Fu Sheng, taking stock of the speeches made by big bosses in the past few months, all emphasized the great opportunities of the application layer.

Internet giants talk about AI nativity: Baidu released more than 20 AI native applications in one breath; ByteDance set up a new team, focusing on the application layer; Tencent embedded the big model into the small program; Ali also wants to do all the applications again with Tongyi Qianwen; Wps crazy gift AI experience card ..

Startups are even more fanatical. After a hackathon, there are nearly 200 AI native projects. Since the beginning of this year, there have been dozens of events and thousands of projects, including Wonderland, Baidu and Founder Park, but none of them came out.

We have to face up to the fact that although we are aware of the great opportunities of the application layer, the big model has not subverted all applications, and all products are being transformed innocently. Although China has the best product managers, they are "out of order" this time.

From the explosion of Midjourney in April to the present, in nine months, the domestic AI native application of "Hope of the whole village" has been brought together. Why is it difficult to give birth?

Choice is more important than hard work. At present, perhaps we need to look back calmly and find the "posture" to correctly open the AI ? ? native application.

First, do AI native, not end to end

Why is the native application difficult to produce? We may find some answers from the "production" process of native applications.

"We usually run four or five models at the same time, which one has better performance." A big model entrepreneur in Silicon Valley mentioned when communicating with Self Quadrant that they developed AI applications based on basic big models, but in the early stage, they didn’t bind a big model, but let each model run up and down, and finally chose the most suitable one.

Simply put, the horse racing mechanism is now involved in the big model.

However, there are still some disadvantages in this way, because although it chooses different large models to try, it will eventually be deeply coupled with one of them, which is still an "end-to-end" research and development idea, that is, one application corresponds to one large model.

However, unlike applications, as a large model at the bottom, it corresponds to multiple applications at the same time, which leads to very limited differences between different applications in the same scene. The bigger problem is that at present, all the basic large models on the market have their own advantages and disadvantages, and no large model has become a hexagonal warrior, which is far ahead in all fields, so it is difficult for applications developed based on a large model to achieve balance in various functions.

In this context, the decoupling of large model and application has become a new idea.

The so-called "decoupling" is actually divided into two links.

The first is decoupling the large model from the application. As the underlying driving force of AI native application, the relationship between big model and native application can actually be compared with the automobile industry.

▲ The picture comes from the Internet.

For AI native applications, the big model is like the engine of a car. The same engine can adapt to different models, and the same model can also match different engines. Through different training, different positioning from mini-cars to luxury cars can be realized.

Therefore, for the whole vehicle, the engine is only a part of the overall configuration and cannot be the core of defining the whole vehicle.

Analogy to AI native application, the basic big model is the key to drive the application, but the basic big model should not be completely bound with the application implementation. A big model can drive different applications, and the same application should also be driven by different big models.

In fact, such examples have been reflected in the current cases. For example, domestic flying books, nails and foreign Slack can all adapt to different basic models, and users can choose according to their own needs.

Secondly, in the specific application, the large model and different application links should be decoupled layer by layer.

A typical example is HeyGen, an AI video company that exploded abroad. Its annual recurring revenue reached $1 million in March this year and $18 million in November this year.

HeyGen currently has 25 employees, but it has established its own video AI model, and integrated the large language models of OpenAI and Anthropic and the audio products of Eleven Labs. Based on different big models, HeyGen will use different models in different links such as creation, script generation (text) and sound when making a video.

▲ Source HeyGen official website

Another more direct case is the plug-in ecology of ChatGPT. Recently, the domestic clipping application Clipping has joined the ecological pool of ChatGPT. After that, users request to call the clipped plug-in on ChatGPT to make videos, and Clipping can automatically generate a video driven by ChatGPT.

That is to say, the many-to-many matching between large model and application can be detailed enough to select the most suitable large model to support in each link. That is, an application is not driven by a large model, but by several or even a group of large models.

Many large models correspond to one application, which is the best of a hundred. In this mode, the division of labor in the AI industry chain will also be redefined.

Just like the current automobile industry chain, every link of the engine, battery, accessories and fuselage has its own specialized manufacturers, and the OEM only needs to select and assemble them to form differentiated products and push them to the market at the same time.

Re-division of labor, breaking the reorganization, not breaking and not standing.

Second, the embryonic form of the new ecology

Under the multi-model and multi-application mode, a new ecology will be born.

According to the map, we try to imagine the architecture of a new ecology based on the experience of the Internet.

At the beginning of the birth of applets, everyone was very confused about the capabilities, architecture and application scenarios of applets. In the early stage, the development speed of applets was very slow, and the number of applets could not advance by leaps and bounds.

Until the emergence of WeChat service providers, service providers connected with WeChat ecosystem, were familiar with the underlying architecture and pattern of small programs, and connected with corporate customers to help customers create exclusive small programs according to their needs. At the same time, they cooperated with the whole WeChat ecosystem to acquire customers and retain them through small programs. The service provider group also ran out of the micro-alliance and praised.

In other words, the market may not need a big model, but it needs a big model service provider.

By the same token, each big model needs to be really used and traded before it can really understand the relevant characteristics and how to play it. In the middle layer, the service provider can not only create a number of big models in backwards compatibility, but also create a benign ecology with enterprises.

According to past experience, we can roughly divide service providers into three categories:

The first type of experienced service providers, that is, to understand and master the characteristics and application scenarios of each big model, cooperate with the industry segmentation scenarios, and open up the situation through the service team;

The second type of resource-based service providers, like the business model that Weimeng was able to get the low-priced advertising space in WeChat and then outsource it, the opening authority of the big model in the future is not universal, and the service providers who can get enough authority will cast early barriers;

The third type of technical service providers, when the bottom layer of an application is embedded with different large models at the same time, how to call and connect multiple models in series, while ensuring stability and security, as well as various technical problems need to be solved by technical service providers.

According to the observation of "self-quadrant", the prototype of large model service providers has begun to appear in the past six months, but in the form of enterprise services, they teach enterprises how to apply various large models. And the way to do application is also slowly forming WorkFlow.

"I’m going to make a video now. I’ll first put forward the idea of a script with Claud to help me write a story, then copy and paste it into ChatGPT, use its logical ability to decompose it into a script, access the clipping plug-in and turn it into a video to directly generate a video. If some pictures in the middle are not accurate, use Midjourney to regenerate them and finally complete a video. If an application can call these capabilities at the same time, it is a truly native application. " An entrepreneur told us.

Of course, there are many problems to be solved in the real implementation of multi-model and multi-application ecology, such as how to communicate among multiple models? How to maximize model calls through algorithms? How to cooperate is the best solution, which is both a challenge and an opportunity.

Judging from the past experience, the development trend of AI applications may be scattered and dotted, and then gradually unified and integrated.

For example, we need to ask questions, make pictures and do PPT. At present, there may be many separate applications, but they may be integrated into a whole product in the future. Move closer to the platform. For example, the previous taxi, take-away, booking and other formats are gradually concentrated into a super APP, and different needs will also pose further diversified challenges to the model’s ability.

In addition, AI Native will subvert the current business model, the hot money in the industrial chain will be redistributed, Baidu will become the shelf of knowledge, Ali will become the shelf of goods, and all business models will return to the most essential part to meet the real needs of consumers, and redundant processes will be replaced.

On this basis, value creation is on the one hand, and how to rebuild the business model has become a more important issue for investors and entrepreneurs to think about.

At present, we are still on the eve of the outbreak of the original application of AI. When it is gradually formed, the bottom layer is the basic big model, the middle layer is the big model service provider, and the upper layer is various startup companies. With such a clear division of labor and benign cooperation, AI native applications can come in batches.

The map in this paper comes from the network.

Bought a Xiaomi 98-inch TV, rights protection can’t be low-key

This article is from the WeChat official account:Zhu Si Ma Ji (ID: zhusimaji88), Author: Fox Ann, the title picture comes from: Visual China

Dear Mr. Lei, Mr. Lu, and friends of Xiaomi Group:

Hello!

Today, on behalf of myself, as an ordinary Xiaomi user and future Xiaomi electric vehicle owner, I am seeking your help from the old rice fans who have used and accompanied this company’s products for more than 10 years.

On April 9, 2020, I officially ordered a 98-inch TV from Redmi priced at 19999 through Xiaomi, order number 5200409269347245 in Xiaomi Mall. This is the first time I have purchased a product with a total price of more than 20,000 yuan in the Xiaomi platform and Xiaomi product series. It is not only a recognition of Xiaomi’s previous products and services as rice noodles, but also a digital enthusiast’s affirmation of Xiaomi’s pioneering use of domestic TV panels and Chinese quality.

At the same time,It was also the first batch of seed users nationwide after Xiaomi entered the super-large-screen TV track.

Due to the over-sized size of the 98-inch TV, it took more than a month from placing the order on April 9 to surveying the site and finally completing the installation on May 13. For the smooth installation of the TV, I agreed with Xiaomi to help me find a crane.The hoisting operation is carried out 40 meters above the ground at a cost of more than 2,500 yuan.The above-mentioned shocking photos quickly sparked heated discussions after being shared through social networks. Mr. Lei and Mr. Lu’s Weibo both affirmed my action in the form of forwarding Weibo. Mr. Lei’s Weibo evaluation at the time was: If you buy 98 inches, you will not be low-key.

My friends in the media, public relations, investment, and boss circles all have fresh memories of this incident.

Due to the fact that the hoisting operation of 98-inch TVs was too popular on Weibo and Douyin platforms, the students of Xiaomi Group followed up and found me, asking if I was willing to authorize the provision of photos of the operation as a follow-up use by Xiaomi. Based on my affirmation of Xiaomi and my trust in Mr. Lei and Mr. Lu, I readily agreed to all Xiaomi’s requests for the use of the above photos for promotion. From placing an order for Redmi98 to hoisting and installation,Until Xiaomi authorized the use of photos, the whole process was my voluntary and spontaneous behavior at my own expense. The subsequent official promotion content did not have any form of cooperation with me.It is based entirely on the passion of a rice noodle.

At the press conference of Redmi’s 86-inch TV on May 26, 2020, the photo of the blue sky and white clouds and the crane on Mr. Lu’s background was from the hoisting operation of my house. As a crazy rice noodle who buys a TV regardless of the cost of the broken window of the crane, Xiaomi’s large-screen TV is famous all over the world, and it has since become a good story.

However, this was not the end of happiness, but the beginning of trouble.

After only 38 days of normal use, Redmi98 experienced regional splash screen and large areas of dark spots.

In the case that the replacement panel was invalid, it was decided to replace the whole machine. As a result, the same failure occurred again 146 days later. Xiaomi once again had to replace the whole TV, but only 44 days after the replacement, the TV still had the exact same problem.When Xiaomi asked for a third replacement, I rejected it. After questioning the product design flaw and asking for a refund of one to three, I had to find a friend from Xiaomi’s Beijing headquarters through personal connections. With the assistance of my friend, the engineer team of the manufacturer made a special trip to Hangzhou for on-site inspection and maintenance.

However, less than a year after this repair, the TV still suffered from a large area of dark spots. In the past three years, Xiaomi engineers and after-sales staff received a total of 5 TV repair reports from me, and completed two complete machine replacements and three complete replacements of the back panel. However, the problem still persists.

Although the engineer team of maintenance and after-sales worked hard, the problem still exists today. When I raised the problem again and did not solve it, Xiaomi after-sales refused to continue to provide after-sales services on the grounds that the product was over-insured. According to incomplete statistics, the normal condition of this TV is only about 55% of the overall time since the purchase. During the five maintenance and replacement processes in the past three years,Xiaomi refused to recall the whole machine and insisted on replacing it with replacement repair, which puzzled me deeply.

Until the last repair in November 2022,It is common to learn from maintenance engineers that the same problem with the same model is common.It is not limited to my case. So from then on, I decided to let go of the rice noodle mentality and try to defend my rights as an ordinary consumer according to China’s consumer protection law. During the process of defending my rights, I told my friends about the many situations I encountered when I purchased a Redmi98 TV, and accidentally discovered through overseas friends that there is a clear difference between Xiaomi in China’s domestic and overseas markets:

Xiaomi has not had an official information disclosure announcement of recall and return to the factory in China, and Xiaomi’s official website has never had an information announcement column setting for suspected recall.However, overseas Xiaomi has a special information prompt column, and regularly publishes relevant information about products with safety and quality hazards due to design defects of relevant Xiaomi products.

Information Tips for Overseas Xiaomi

Such as the above-mentioned global recall notice of Xiaomi’s M365 electric scooter being sold overseas with potential safety hazards, there is a clear contrast with the so-called "domestic recall" of the previous 2022 Xiaomi 11 mobile phone with quality problems and only providing replacement panels and extended warranty services in China. The above behavior immediately reminded me of Tesla China, which had disappointed me before.

In the literal sense, replacement repair is indeed a clever after-sales processing method and clever text narrative method compared to recall means. For small-sized, low-tech value-added mobile phones and smart home products in the early years, the labor cost of engineer maintenance is much higher than replacement, so for a long time as a rice fan, I have been praising Xiaomi’s service system.

However, as Xiaomi’s products and technologies gradually moved into the deep water area, more and more high-end product sequences began to be laid. After large-scale, high-tech value-added products entered the market, the consumption-upgraded rice noodles and Xiaomi after-sales services inadvertently changed on the demand side.Rice noodles that buy high-end serial products hope to get reliable and safe quality. Xiaomi after-sales service must also take into account user requests and practical cost issues while providing convenient services.As Xiaomi, which is about to enter the new energy vehicle track, and as a rice noodle who is watching with coins, I can’t help but ask Mr. Lei four questions:

Finally, thank you for taking the time to read my letter in your spare time. Although the current situation of rights protection is very difficult, it may be fruitful after suffering and tossing, because I firmly believe in the famous saying – "always believe that good things are about to happen".

Looking forward to your reply from Mr. Lei.

On June 20, 2020, the first after-sales warranty was provided to Xiaomi 38 days after the installation was completed. The 98-inch TV had the problem of frequent regional splash screens. After remote assistance from engineers, the software settings and function key operation resets were invalid, and the after-sales service said it was waiting for the company’s material accessories to arrive.

On July 2, 2020, the Xiaomi engineer team carried out the first door-to-door dismantling and installation, and replaced several panels on the back of the TV. After the power-on test was successful, the after-sales service was completed. Unexpectedly, in the early morning of the next day, the TV flashed again. After giving feedback to the after-sales service, the after-sales service had to report to the leader.

On July 8, 2020, Xiaomi informed the after-sales service that the TV would be replaced and told to cancel the maintenance order. After a few days of confirmation, the familiar crane, the familiar onlookers, and the familiar 40-meter broken window operation happened again, but this time compared to the last hot search, the onlookers found a TV that was taken away from a height of 40 meters.

On December 1, 2020, the regional flash screen of the new Redmi 98-inch TV was again replaced. The difference is that the position of the regional flash screen has changed from the bottom left to the bottom right. At the same time, there are also multiple black shadow blocks on the TV(Disappears after reboot, but will still appear later.)

On December 7, 2020, the after-sales service conveyed that the application for the second replacement of the 98-inch TV set had been approved. For the first time, I raised doubts about the replacement repair treatment method, but the after-sales service said that the 98-inch TV set was repaired on the spot, so it could only be replaced.

On December 25, 2020, the Xiaomi engineer team carried out the second replacement, which was still a hoisting operation. I said that the two replacement and hoisting were the limit of my tolerance for Xiaomi products, and I don’t want another one.

On February 7, 2021, the second replacement of the 98-inch TV failed again, causing a large area of dark spots to continuously expand, affecting normal use.

On February 9, 2021, the after-sales service expressed whether to accept the third replacement, but I rejected it. At that time, two plans were proposed: 1. Refund one to three according to the elimination insurance, and recycle this paranormal TV. 2. In the case of no replacement, the cause of the TV failure must be found and repaired.

On February 22, 2021, the after-sales service conveyed the leader’s meaning: either return it or change it. The 98-inch TV did not refund one to three, and the door-to-door maintenance was said.I had to contact my friends at Xiaomi headquarters in Beijing through my identity as a media person other than an ordinary user, and directly give peer-to-peer feedback to the executives of the Redmi team, expressing my willingness and determination to solve the problem, hoping to end the torture before the arrival of 315.

On February 24, 2021, a team of experts from the Redmi factory in Jiangsu drove hundreds of kilometers to Hangzhou. They conducted tests and inspections at my house for several hours. For the engineers who came from afar, I treated them with sincerity. Not only did I smoothly report the problems encountered before to the engineers and put forward some opinions and guesses of quasi-professional users, but I even entertained the technicians of the engineer team to have a hot pot together until nearly 6 pm that day. The engineer team finally came to a conclusion that the wall bracket installed by the TV had been damaged due to the tilt of the installation angle. After the engineers replaced the damaged parts and adjusted the installation wall hanger, the TV returned to normal.

On February 2, 2022, I reported to Xiaomi for the fourth time that there was an abnormality in the TV, and a large area of black shadows appeared. However, due to the severe epidemic in 2022, my community was sealed and controlled soon after due to confirmed cases. The door-to-door maintenance was delayed again and again, and I could only endure the dark spots and wait for the epidemic to improve.

On November 26, 2022, Xiaomi engineers came to the door for the fifth time and replaced the backplane. The engineer said that the previous backplane of this TV was no longer produced, and this time it was the latest model.And informed because my TV has been out of warranty, so this service is a special repair, but there is no next time.

On November 30, 2022, I reported to Xiaomi for the fifth time that the black shadow of the TV still exists, but the position has changed, appearing on the upper side of the TV center. However, Xiaomi after-sales said that it has reported to the leader, but has not received a reply so far.

As of March 15, 2023, the Redmi 98-inch TV has not been repaired.

Are you stupid about Aion V 13 configurations? I’ll tell you which one is the most suitable today! Which one can’t be bought!

 Since its debut, Guangzhou Automobile New Energy Aion V has attracted numerous attention with its mecha modeling, large space, L3 autopilot, 5G smart health seat and 600 km long battery life. After the official listing on June 16th, it directly blinded my titanium alloy eyes with as many as 13 configurations. 13 configurations, are you stupid? A few days ago, we also received a message from our friends that their configuration table was too complicated, and we hope to make a configuration analysis. No problem, arrange! Today, I will talk to you about how to play these 13 configurations.

 Specific configuration and price

At present, we can see that Aion V has 13 configurations in official website, Guangzhou Automobile New Energy Co., Ltd., covering four kinds of cruising range, which are 400/500/530/600 kilometers respectively, and the corresponding vehicle names are 60/70/70PLUS/80 respectively. Among them, the 400-kilometer endurance version and the 530-kilometer endurance version have only one configuration of 60 and 70PLUS respectively, and the 70 and 80 models have five configurations, namely, Smart Collar Edition, Enjoy Healthy Edition, Enjoy Smart Technology Edition, Enjoy Smart Driving Edition and Enjoy Smart Zun Edition, and 80 MAX exists as the top model of the 80 version, that is, 5 * 2+1+1 = 13. Between 239,600 yuan.

Is the basic configuration fragrant?

Let’s take a look at the basic configuration of the whole car system — — 60 Smart Collar Edition is classified from four aspects: appearance, interior decoration, safety and technology. See the table below for the specific configuration.

Each of them has a more practical bright spot configuration, such as the appearance of LED head taillights, 19/20-inch rims, etc. Interior, four-door window one-button lifting, CN95 air conditioning filter, remote one-button antivirus, etc. The safety configuration is very complete, including ESP, ABS, tire pressure monitoring and front side airbags. In terms of science and technology, dual 12.3-inch display screens, keyless entry, wireless networks, etc. are also full of science and technology.

What are the differences between the configurations?

Let’s look at the "5*2" part first. The 70 and 80 models have 5 configurations respectively, and the price difference between adjacent configurations under each model is the same, as shown in the following table.

First of all, it is clear that the difference between the same versions of 70 and 80 models is mainly the difference in battery life. The battery life of 80 models is more than 100 kilometers, and the corresponding versions are all different by 22,000 yuan. On the Aion S, the same configuration with different battery life (a difference of 100 kilometers) is 13,000 yuan, and the Aion V is more expensive. In addition, 80 models are equipped with 20-inch rims (other models are equipped with 19-inch rims) plus some optional packages, such as 5G Pioneer Suit and Luxury Smart Suit. Only 80 models can choose. Let’s put the five configurations of 70 and 80 models together and look at the differences between them.

Smart collar edition

Compared with the 60-degree smart collar version, the 70/80 smart collar version has five super-practical configurations, including the automatic induction opening of the headlights, the sunshade of the electric sunroof, the automatic folding of the rearview mirror, the defrosting and defogging functions, the intelligent automatic rain sensor wiper, the 360-degree panoramic parking image system.

The 70-smart version has a battery life of 100 kilometers longer than the 60-smart version plus five practical configurations, and the difference is 18,000 yuan. Compared with the 70-collar version, the 80-collar version has 100km battery life and 20-inch rims, with a price difference of 22,000. Obviously, 70 Smart Collar Edition is a wise choice.

Enjoy the healthy version

Compared with the smart-collar version, Enjoy Health Edition has more PM2.5 sensor +AQS air quality sensor+fragrance system, and the price difference is 4,200 yuan.

The added configuration is mainly aimed at the air quality sensor in the car. If the air quality in your living environment is poor all the year round, you can choose this configuration. In my opinion, there is no need to spend 4200 more for these, and the cost performance is low. After all, the environment in most cities is not as bad as this. In addition, after paying attention to the environment at the national level, the negative examples represented by Beijing have continued to improve significantly in recent years. It is really necessary to monitor the air quality inside the car. You can buy a small instrument online and get it for a few hundred dollars.

Zhixiang technology ban

Zhixiang Technology Edition has 9 configurations more than Changxiang Health Edition, with a price difference of 5,000 yuan.

As you can see, this 5000 yuan is enough to increase the configuration. Among them, the "owner’s super account" can realize the functions of car body control and automatic account identification, and wireless charging of mobile phones and virtual keys are also practical functions in daily life. This configuration of 5000 yuan is quite cost-effective and worth recommending.

In addition, 80 Zhixiang Technology Edition can also be equipped with luxury smart suits, which can have more choices.

Yue Xiang zhi Jia ban

On the basis of enjoying the healthy version, Yuexiang Intelligent Driving Edition adds an electronically controlled power-assisted braking system +ADiGO automatic driving system. Among them, ADiGO autopilot system can realize lane keeping, adaptive cruise, active braking, face recognition and other functions. That is, an L2 driver’s assistance suit+electronically controlled power-assisted braking, with a difference of 8,000 yuan.

It should be noted that the Enjoy Smart Drive Edition adds the above configuration on the basis of Enjoy Healthy Edition, but it has no additional technology configuration (9 items listed in the above table) than Enjoy Healthy Edition. If you have a need for L2 autopilot, you can consider it. Otherwise, Zhixiang Technology Edition is cheaper and more practical.

Enjoy the wisdom edition

Driving the Smart Edition is based on the Smart Edition, which adds an electronically controlled power-assisted braking system and one-button remote parking, with a total difference of 6,200 yuan, of which remote parking was originally scheduled to be delivered. For some female drivers who have the shadow of parking, it may be love at first sight for remote parking. With it, my mother no longer has to worry about my parking. For most people, this 6200 yuan is not worth it.

Let’s look at the part of "1+1+1".

60 smart collar edition

The 60 model has only one configuration of the smart collar version, and the only model with a battery life of 400 kilometers and a rear torsion beam dependent suspension (other models are rear multi-link independent suspensions). Compared with the 60-smart version, the 70-smart version has five super practical configurations, such as automatic induction opening of headlights and electric sunroof. Compared with the 70 Smart Collar Edition, the price difference is 18,000 yuan, 100 kilometers more battery life+rear multi-link suspension +5 practical configurations. Obviously, the 60-smart version is low in cost performance. In addition, the 60 Smart Collar Edition does not have any right to choose packages, which further limits everyone’s freedom of choice.

70 Plus smart collar edition

The existence of the 70 Plus smart collar version with a battery life of 530 kilometers is a bit of a chicken rib, only 30 kilometers more than the 70 smart collar version, and the difference is 6000 yuan. If it is to increase the battery life, it will not be only 30 kilometers more. This wave of operation by the manufacturers has also confused me. It should be noted that for the 400-kilometer and 500-kilometer endurance models, the battery pack uses Funeng battery, and the battery capacity is 52.4 and 69.9 kWh respectively; For the 530-kilometer and 600-kilometer cruising models, the battery pack uses AVIC battery, and the battery capacity is 73.3 and 80 kWh respectively. If you value the battery brand, just choose it as needed. In addition, the 70 Plus Smart Collar Edition does not have any right to choose an optional package.

80 MAX

80 MAX has added solar sunroof, electric tailgate, rear privacy glass, ADiGO autopilot system and luxury smart suit on the basis of the 80-driver version. Among them, the main driver’s seat memory and AR navigation in the luxury smart suit can fully support you to install a 13 occasionally; For friends with camping hobbies, you can also meet your outdoor electricity demand through a two-way 6.6 kW charger. In addition to the slightly higher price, the configuration is absolutely nothing to say.

What are the optional packages?

One-button remote parking set

The 70/80 driving smart edition has been equipped, so you don’t need to choose it. The 60/70Plus smart collar edition is not optional. The other 9 models are optional, and the optional price is 12,400 yuan. In my opinion, this optional package is low in cost performance, and it is unnecessary to choose it except for those female drivers who have "storage shadow".

ADiGO 2.5 automatic driving assistance package(that is, L2.5 automatic assisted driving)

The 70/80 Enjoy Smart Driving Edition equipped with ADiGO automatic driving system (L2 automatic driving assistance) is not optional, and the 60/70Plus Smart Collar Edition is not optional. The other nine models are optional, and the optional price is 9800 yuan (half price concession), which is still very affordable.

ADiGO 3.0 automatic driving assistance package

Only 80 MAX can be installed, and the optional price is 28,600 yuan. This optional package is not only expensive, but when L3 will be opened is still unknown. Unless you have a strong desire for L3, it is not recommended.

5G pioneer suit

80 models are optional, and the optional price is 9600 yuan. It should be noted that if 80 MAX is equipped with ADiGO 3.0, you can’t install 5G Pioneer Suit at the same time. This is because the current ADiGO 3.0 needs to use a high-precision map positioning module, which is developed based on the 4G network architecture. High-precision maps based on 5G network architecture are still under development.

Luxury smart suit

In addition to the 80 MAX already equipped, only 80 Zhixiang Technology Edition and 80 Driving Zhixiang Zun Edition can be installed, and the optional price is 9600 yuan. The optional package specifically includes 8 items such as ventilation/heating of front seats and AR navigation, which can be seen as some practical configurations. This optional package is quite cost-effective and worth buying.

How to buy it specifically?

1. How to choose the comprehensive cost performance?

Recommended model: 70 Zhixiang Technology Edition.

Recommended index:★★★★★

Highlight: As far as comprehensive cost performance is concerned, 70 Zhixiang Technology Edition has the highest cost performance, 186,800 yuan, which can have the high value, large space and 500 km long battery life of AION V. At the same time, the main drive 6-way electric adjustment, mobile phone wireless charging, Bluetooth virtual key and other technical configurations are also available, which can fully meet your daily car needs. Overall, the cost performance is quite high, which is worth recommending.

2. How to choose the mecha style and large space of Aion V only?

Recommended model: 70 smart collar version.

Recommended index:★★★★

Recommended reason: Because all models have the same shape and space, if you only value the mecha style and large space, you should choose the cheapest 60-smart collar version. However, compared with the 60-smart version, the 70-smart version is 18,000 yuan more expensive, with 100 kilometers more battery life and 5 practical configurations (mentioned above). The 80-smart collar version is 22,000 more expensive than the 70-smart collar version, with 100 kilometers more battery life and 20-inch rims. The 70Plus Smart Collar Edition is 6000 yuan more expensive than the 70 Smart Collar Edition, and the extra 30 kilometers of battery life is very tasteless. Obviously, the 70 Smart Collar Edition has the highest cost performance, and it is the most suitable partner for such needs.  

3. How to choose the long battery life of Aion V?

Recommended model: 80 smart collar version

Recommended index:★★★★

Recommended reason: 80 models have a battery life of 600 kilometers, and friends who value battery life directly choose the low allocation of 80 models — — The 80 Smart Collar Edition, although slightly inferior in some aspects of technology configuration, is still worth recommending in terms of battery life and pricing. Suitable for those small partners who have low configuration requirements, limited budget and long battery life.

4. How to choose long battery life+automatic driving?

Recommended model: 80 Zhixiang Technology Edition +ADiGO 2.5

Recommended index:★★★★

Highlight: If you want a long battery life, lock the 80 models. In terms of autonomous driving, the current ADiGO 2.5 package is half price, as long as 9800 yuan. Moreover, it can be found from the official of GAC New Energy that ADiGO 3.0 only adds "HF+ high-precision map for highway driving assistance" on the basis of ADiGO 2.5, and it will take half a year for ADiGO 3.0 to be delivered.

Therefore, on the whole, friends who value long battery life and automatic driving can choose 80 Zhixiang Technology Edition +ADiGO 2.5 automatic driving assistance package. You can enjoy the ADiGO 2.5 optional package at half price, and you can pick up the car as soon as possible.

 5. How to choose L3 autopilot that values Aion V?

Recommended model: 80 MAX+ADiGO 3.0

Recommended index:★★★

Highlight: 80 MAX is equipped with ADiGO automatic driving system, and it is also the only model that can be equipped with ADiGO 3.0 automatic driving assistance package. If you are driving for L3 of Aion V, 80 MAX will be the only option. Of course, for a small partner with sufficient budget, it is quite worry-free to directly choose the top match in one step. However, according to the current news, the optional ADiGO 3.0 will have to wait for about half a year before it can be delivered.

It should be noted that the current regulations do not fully permit L3 autopilot. The official statement of GAC New Energy is that "it can be opened when the regulations permit", but when it can be opened is still unknown.

6. Which models are not recommended?

1)60 Smart Collar Edition.

With a battery life of 400 kilometers, it is weak in the mainstream market, and the rear suspension of the 60-collar version is a torsion beam non-independent suspension. The most important thing is that as long as the price is increased by 18,000 yuan, you can buy the 70-smart version, and the battery life is increased by 100 kilometers. There are also super practical configurations such as automatic headlights, electric sunroof, rearview mirror automatic folding and defrosting and defogging functions, and 360-degree panoramic parking image system. In contrast, the 60-smart version is much less cost-effective.

2)70 Plus Smart Collar Edition.

This configuration is very thin, only 30 kilometers more battery life than the 70-smart-collar version, and the price is 6000 yuan more. I think the extra 30 kilometers can’t solve everyone’s pursuit of high battery life, and there is no need to spend 6000 yuan more.

3) If you are not rushing to install ADiGO 3.0, it is not recommended to buy 80 MAX.

Let’s calculate an account. If the 80-driver version is equipped with ADiGO 2.5+ luxury suit, the price will be 234,400 yuan. It includes L2.5 assisted driving+one-button remote parking.

80 MAX’s one-button remote parking needs to be optional, so the price is 252,000 yuan. Among them, the assisted driving is L2, but it has more solar sunroof, electric tailgate, privacy glass in the rear row and automatic anti-glare in the interior rearview mirror than the 80-driver version (optional ADiGO 2.5+ luxury suit). 80 MAX is 17,600 yuan more expensive. Do you think it’s worth it?

If the 80 MAX is not equipped with one-button remote parking, the price is 23.96. It is 5200 yuan more expensive than the former, with the above four configurations, but one-button remote parking is missing, and the automatic driving level is one grade worse. Do you think it is worth it?

■ State Review

Generally speaking, Aion V has many vehicle configurations, which may be difficult in the initial selection, but it also gives you more choices. Whether you are pursuing high face value and long battery life, or pursuing technology configuration and autonomous driving, you can find what you want in AION V. Have you decided which one to buy?

The film market of Qingming file is expected to usher in "Xiaoyangchun"

  The "smoke" of the Spring Festival movie market has just dispersed, and the "post-Spring Festival file" has ushered in a new round of box office war. According to the data of Lighthouse Professional Edition, there have been 8 movies scheduled for Qingming this year. The number of movies released in this year’s Spring Festival is only 9, including some retired movies, and the actual number of movies released is less than 8. This means that the competition level of Qingming file this year is comparable to or even exceeds that of Spring Festival file.

  According to the past rules, the month after the Spring Festival is the off-season of the film market. However, in March this year, it was "uncharacteristic" and the "heat wave" did not decrease. More than 30 films have been scheduled for March, involving science fiction, action, suspense, love and many other themes. Among them, imported large-scale "hard dishes" frequently, including Dune 2, Trial of Falling, and other well-received works.

  Huachuang Securities suggests paying attention to: 1) quality content producers: () (24 years of product year, Nezha 2/Xiaoqian is expected to be released), (), (), etc. 2) Leading cinema and online ticketing: () (change of actual controller, pay attention to positive changes of the company), Maoyan Entertainment, etc.

  Guosen Securities said that the film market is expected to continue to recover, focusing on cinemas, content and related industrial chains. The supply cycle of high-quality content at home and abroad is superimposed with strong demand for watching movies, and the film market is expected to usher in a sustained recovery. 1) Recommend cinema and ticketing from a deterministic perspective, and recommend WANDA CINEMAS and Maoyan Entertainment as the core, among which WANDA CINEMAS is expected to receive the whole industry chain dividend of industry restoration, and the market share of cinema leaders has steadily increased under the epidemic situation, and the resilience is stronger under the small and medium-sized clearing; Maoyan Entertainment: The online ticketing market enjoys a stable pattern of industry recovery, and the upward layout of content production is expected to gain higher flexible return opportunities; 2) We are optimistic about the content supply side of the industry for 24 years from the perspective of flexibility, pay attention to the combination of films and the possibility of box office exceeding expectations from the bottom up, and mainly recommend the light media, () and (); 3) Pay attention to the relevant links of the film industry chain besides the content and cinema, a) film distribution, ticketing and other links; B) A special effects technology cinema to enhance single-screen output; C) film and television copyright links, etc. (()); 4) Pay attention to the box office performance of imported films.

"Retirement" of the First Batch of New Energy Vehicle Batteries: Facing Three Challenges

  With the dual drive of policy and market, China’s new energy vehicle market has experienced explosive growth in the past 10 years. However, it should not be ignored that the first batch of power batteries for new energy vehicles are aging, and a "retirement tide" of power batteries is coming.

  According to the quality assurance ability of 20% battery decay in 8 years of general vehicle manufacturers, China has ushered in a rapid increase in the number of retired power batteries for new energy vehicles since 2017. It is estimated that the number of retired batteries will reach 9.3 billion watt-hours in 2025, and the number of retired batteries will increase by more than 1 million orders of magnitude every year. This will bring huge potential market value of ladder utilization. If the retired batteries are recycled according to the method of first step and then regeneration, it is estimated that the total market size will reach 37.9 billion yuan by 2025.

  As we all know, batteries contain a variety of heavy metal elements, which will cause environmental harm if not handled properly. What will happen when the waste power battery has a huge potential market scale and meets the recycling market system that needs to be improved? What are the "blocking points" that need to be opened?

  1. Value and risk of a "retired" power battery

  According to the national standard of new energy vehicles, power batteries can often be "retired" with more than 80% remaining. This makes the power battery still have great use value after it is retired from the vehicle, which not only forms a huge potential market, but also means certain environmental risks.

  "Generally speaking, after the service life of power batteries is 5-8 years, we encourage ‘ Retired ’ Step use of battery. Although the battery’s cruising range is reduced, it can’t meet the needs of vehicles, but it can be recycled for other energy storage needs, and it can still continue ‘ Service ’ For a while, you can also choose the recycling of batteries in the future. " Jia Jingchun, an associate professor at the School of Chemistry and Environmental Sciences of Inner Mongolia Normal University, introduced.

  Liu Wanmin, an associate professor at material chemistry of Hunan Institute of Technology, told the reporter: "‘ Retired ’ Power batteries can be widely used in power system energy storage, backup power supply for communication base stations, low-speed electric vehicles and small distributed household energy storage, wind and solar complementary, electric forklifts and other fields. Generally, it can be used to about 60% of the initial capacity of the battery. According to different usage scenarios, the service life can range from several months to several years. "

  It still has the use value of several years, which makes "step by step utilization first, then recycling" become the first choice for recycling "retired" power batteries. Cascade utilization refers to the application of "retired" power batteries in other fields. Recycling is to disassemble, crush and screen the "retired" battery, and extract lithium, cobalt, nickel and other metal elements from the battery by leaching hydrometallurgy or pyrometallurgy, and use them in the production of secondary batteries.

  The reporter learned that power batteries contain metal elements such as lithium, cobalt, manganese and nickel, and the cost of raw materials accounts for 50%~70% of the total cost. The lithium salt and cobalt salt consumed by power batteries have become the largest proportion in all application fields of lithium and cobalt. With the rapid consumption of primary resources, the recovery of secondary resources should reach the corresponding level. Since the release of National Mineral Resources Planning (2016-2020), China has reserved rare earth metal minerals as strategic resources. Therefore, recycling metal elements in power batteries can not only better develop circular economy, but also effectively alleviate China’s long-term dependence on such resources.

  However, Jia Jingchun also pointed out that lithium batteries contain heavy metals such as lithium, and some batteries use organic electrolytes and organic separators. Different from the simple recycling method of traditional lead-acid batteries, the metal recycling process of lithium-ion batteries is relatively complicated. Once improperly operated, these heavy metals and organic electrolytes will bring serious threats to the environment.

  "After the battery is dismantled, we generally use hydrometallurgy or pyrometallurgy to recycle lithium, nickel, cobalt and other metal elements. Improper disassembly will lead to many problems such as safety, environment and resources. From the safety point of view, there are hidden dangers such as electric shock, short-circuit explosion and hydrofluoric acid corrosion. From the environmental point of view, there are heavy metal pollution such as cobalt and nickel, fluorine pollution and white pollution caused by battery diaphragm. From the perspective of resources, there is a waste of high-priced resources such as lithium, nickel and cobalt. " Liu Wanmin said.

  2. Battery recycling enterprises face three major challenges.

  Although the recycling potential is huge, at present, there is no leading enterprise in the power battery recycling market, and even some chaos has occurred. Earlier, some media reported that many host manufacturers have established battery recycling business. However, some power batteries did not flow into the formal channels, but were bought at high prices by unqualified and highly polluting small factories and improperly treated, causing hidden dangers of secondary environmental pollution. Why is this so?

  "First, at present, users of new energy vehicles are not strong enough to recycle power batteries; Second, the recycling price of some small workshops is much higher than that of regular recycling enterprises; Third, the enterprises that recycle batteries have high qualification requirements, which leads to a limited number of formal recycling enterprises; Fourth, the recycling technology is immature and the recycling business model lacks innovation. " Liu Wanmin analyzed.

  Among them, the ladder utilization and recycling is the most difficult. Although China has become the country with the best development of new energy vehicles in the world, power battery is still a new technology. In the eyes of the industry, enterprises still face three major challenges in battery recycling: inconvenient battery disassembly, unknown residual value of battery health and low economic benefits.

  The complexity of "retired" batteries is high. Different power batteries have different internal and external structural designs, module connection methods and process technologies, and only have square, cylindrical, soft bag and other shapes. This directly led to the later disassembly work can not be large-scale operation, which increased the difficulty of disassembly and labor costs. If the operation is improper, it is more likely that short circuit will cause fire or explosion, leakage will pollute the surrounding environment and threaten the health of employees, resulting in casualties and property losses.

  At present, there is no data record of the usage of some "retired" power batteries, only the original data when they leave the factory, and the usage process and current state are unknown. Before the power battery is used step by step, each module must be tested, which greatly increases the cost of the enterprise. At the same time, based on the limited data, the prediction of the remaining life is not accurate enough, which will undoubtedly increase the quality risk of the products.

  The above factors make the economic benefit of recycling power batteries low. A staff member of a battery recycling enterprise told the reporter that the small workshop gave up many key links such as detection and discharge in battery recycling, and the operators did not receive professional training, so the operating cost was much lower than that of regular enterprises, thus having more room for bargaining power and battery acquisition cost, which caused vicious competition with regular enterprises.

  3. The maintenance traceability of the "ID card" of the power battery has not been smooth.

  In fact, as early as 2016, China has issued the "Implementation Plan for Extended Producer Responsibility System", requiring the establishment of a recycling system for electric vehicle power batteries. The plan points out that electric vehicle and power battery manufacturers should be responsible for establishing a waste battery recycling network, recycling waste batteries through after-sales service network, and publishing recycling information to ensure standardized recycling and safe disposal of waste batteries. Power battery manufacturers should implement product coding and establish a full life cycle traceability system.

  On July 31, 2018, the national monitoring platform for new energy vehicles and the comprehensive management platform for the traceability of power batteries (hereinafter referred to as "the national traceability management platform") was launched. The platform was built by the National Engineering Laboratory for Electric Vehicles of Beijing Institute of Technology, and its main function was to collect information and monitor the whole process of power batteries’ production, sales, use, scrapping, recycling and utilization, so as to realize that the source of power batteries can be traced, the destination can be traced and the nodes can be controlled.

  At present, the national traceability platform has collected more than 5.6 million vehicle information data, including new energy passenger cars, buses, special vehicles, etc., and the total number of supporting batteries exceeds 8.9 million, with batteries exceeding 28 billion watt-hours. It involves more than 290 new energy vehicle manufacturers and more than 180 battery companies.

  The establishment of the whole life cycle traceability system means that every car’s battery has its own "ID card". But why do batteries still flow into small workshops? Some insiders pointed out that although China has established a traceability management system, due to the lack of mandatory policies, enterprises have problems such as serious lag, incompleteness and difficulty in traceability when reporting data. At the same time, the current policies and regulations are not binding on how car owners deal with batteries, which also gives small workshops an opportunity to buy power batteries.

  "In 2015, China’s technical policy has clearly stated that a power battery coding system will be established. The Interim Measures for the Management of Recycling in 2018 proposed the establishment of a power battery traceability information management system, coding technical standards and related information sharing mechanisms. However, in reality, there are many types and quantities of enterprises involved, such as battery manufacturers, battery maintenance and replacement institutions, battery leasing enterprises, and cascade utilization enterprises. The battery life cycle is as long as several years, and coding maintenance is difficult. " Liu Wanmin said.

  Jia Jingchun said: "Professional battery recycling is a large-scale system engineering. How to recycle requires coordination from all sides, especially the cooperation of automobile manufacturers, battery manufacturers and related extension industries. Once a link in the whole cycle is unreasonable, it will inevitably lead to problems of lag and other derivatives in recycling. "

  4. The national standard system for battery recycling still needs to be improved.

  By the end of 2020, China’s National Standardization Administration Committee has issued five national standards for the recycling of vehicle batteries, basically forming a standard system framework. In addition, the regulatory policies for the recycling of power batteries, the relevant standards of the echelon industry and the industry regulatory system are also being improved. However, some insiders pointed out that most of the standards currently issued are recommended standards, and there are problems such as insufficient binding force and lack of superior law in the implementation process.

  "At present, new energy owners are interested in ‘ Retired ’ In fact, most people are still vague about how to dispose of batteries. Some car companies have introduced battery replacement, such as full mileage or ‘ Service ’ Time for battery replacement and recycling. However, the large-area battery life of new energy vehicles has not yet arrived. " Jia Jingchun said that he pointed out that over time, new energy owners will gradually become more experienced in how to properly handle power batteries. "At present, we should establish corresponding supervision and legislation to ensure that used batteries can be returned to manufacturers or recycling enterprises. At the same time, the supervision of battery production and use must be formed. After leaving the factory, traceability, use tracking and battery destination after use all need a set of supervision mechanisms. "

  Many experts in the industry pointed out that in order to speed up the recycling of power batteries, in addition to strengthening the implementation of the producer extension system, there are still three aspects to be improved in the future: first, we must strengthen publicity and raise consumers’ awareness of environmental protection; Second, we should formulate policies to subsidize or reward enterprises that actively participate in battery recycling, and at the same time crack down on non-compliant recycling; The third is to speed up the transformation of intelligent equipment in enterprises, improve the efficiency of battery recycling, reduce the recycling cost through economies of scale, improve the bargaining power of enterprises, and provide effective protection for the normal operation of enterprises, thus fundamentally solving the industrial problems of high cost and low profit and guiding the further standardization of battery recycling.

  As many batteries go online, there are many batteries to be "retired". As an important part of the development of new energy vehicle industry in the future, the healthy and standardized development of power batteries is very important.

  This year’s government work report mentioned that the construction of power battery recycling system will be accelerated. At the national level, China has accelerated the legislative process of power battery recycling. In addition, the reporter learned that on March 29, 2021, the national evaluation and trading platform for "retired" power batteries of new energy vehicles (also known as battery house) was established in Foshan City, Guangdong Province.

  The platform will aggregate the resources of the National Engineering Laboratory for Electric Vehicles, the National Monitoring and Management Platform for Battery Traceability and the specialized committee for recycling new energy batteries, and strive to maximize the battery utilization rate. Based on the blockchain technology, it will provide many services for new energy automobile enterprises, such as performance evaluation of big data power batteries, offline laboratory testing and online trading of power batteries, and it is also expected to help solve the industrial problems such as difficult recycling, limited sales channels and lack of rapid performance testing technology in the recycling of power batteries.

Badminton footwork caught in one net (multiple pictures)

1, how to start

This is the most important step in badminton.

I’m here to prepare. I don’t know where the ball will go before the opponent hits the ball.

After my opponent hits the ball, I have to react in a short time.

Therefore, I must take a step to push my body to the ball as soon as possible.

With Figure 01, the first step is "starting step"

Second, how to stop

The second element of badminton pace is how to stop.

Stop, including two parts:

First, the toes should point to the ball.

In this way, you can have a stable posture and good balance.

Photo 02 Toe points to the ball.

But many people point their toes there (the midline), which is very dangerous

When your toes point to the ball, your knees can bear the weight of your body.

You can’t do this (toes pointing to the sideline), it will be worse.

Remember, your toes must point to the ball.

The second is how to get close to the ball.

You should keep an eye on your opponent when you are close to the ball.

Pay attention to the direction of my face so that I can have a better view.

Therefore, my approach to the ball should be like this.

Figure 03 The action of approaching the ball

Don’t just watch the ball, watch the opponent’s court at the same time.

Point your toes at the incoming ball, and look at your opponent’s court, not in other directions.

Third, how to return?

For example, after I hit the ball in the frontcourt, how can I return to my position and prepare for the next shot?

1. The first step of return

Photo 04 Return to the First Step

Hit the ball and get ready (with your feet back)

Hit the ball, get ready

Then come back slowly.

Photo 05 The frontcourt moves to the backcourt

Picture 06 Moving to the frontcourt is the same.

Picture 07 The same is true when moving to the side.

Photo 08 The same is true in front of the backhand net.

Without this first step of returning, it would be like this. My movement will die.

Photo 09 One-step return is wrong.

The important role of the first return step is to wait for the direction of the opponent’s ball.

Pay attention to the overall movement of the male student and focus on his legs.

After hitting the ball there, he didn’t know where his opponent’s next ball would go during the return.

Because of this, he must pause and pay attention to his overall movement rhythm.

Figure 10 The rhythm of returning to the net.

After hitting the ball, he immediately made the first step of returning, and then slowly returned.

2. The second step of return

After hitting the ball, he immediately made the first step of returning, and then slowly returned.

In the process of his return, when the opponent hits the ball, he can know where the ball is going and start it immediately.

As you can see, while he is slowly returning to his position, he is also waiting for the ball.

Photo 11 The second step of the female player slowly

If her opponent makes a fake move, if her return movement is done correctly, it is not easy to be cheated.

While she was still moving back in the air, she was also waiting for her opponent to hit the ball.

Let’s compare, if there is no first small step and a slow second step.

Figure 12: Slow second step can prevent cheating.

This small step will ensure that you keep moving.

The next move is a slower process to observe the opponent’s stroke.

This will ensure a good connection between the two shots.

Four, doubles before the net to save the ball footwork

The steps of throwing the ball in front of the net in doubles and mixed doubles can be divided into three steps:

Get ready, hit the ball, get ready;

Figure 13. Ball-saving footwork in front of doubles net

The key point here is the preparation after hitting the ball, and preparing the return ball in all directions.

The point is, get ready immediately after hitting the ball.

Fifth, the footwork of moving in front of the net in singles

If I put the net in front of the net, then I have to have the pace of returning.

Maybe four or five steps.

Take a look, in front of the forehand net

If the ball is far away, it is five steps.

If the ball is close, it is four steps.

Figure 14 Moving footwork in front of the net in singles

Photo 15 Female students hit the ball in front of forehand net

2. Hit the ball with backhand in front of the net

It can be four steps, and if it is a save, it is three steps.

Photo 16 Female students hit the ball in front of the backhand net

3. Forehand and backhand footwork

Pay attention to the pace of landing with both feet at the same time, which is the most important point.

Let’s do five forehand steps and four backhand steps on both sides

Pay attention to the timing of landing, just after the opponent hits the ball, not at the same time or in advance.

Figure 17 Forehand and Backhand Footwork

Six, doubles forehand net before picking the ball footwork

Key points to remember:

1. "Step One"

2. The pace of returning after picking the ball

3. Move before the next "first step" after returning to the middle.

Figure 18 Movement before "the first step"

Figure 19 Step 1

Figure 20 Footwork of Return

With Figure 21, pay attention to the "first step" to start moving.

Photo 22 The "first step" of the two men is simultaneous, just after the opponent hits the ball.

Figure 23 Footwork of Return

Seven, doubles backhand before the net to pick the ball footwork

According to the distance of the ball, it takes four or five steps to pick the ball in front of the backhand net.

Including starting, stopping and returning.

Photo 24: Picking the ball in front of the backhand net in doubles.

Eight, doubles forehand draw footwork.

There are five steps in forehand draw.

Photo 25 Footwork of Forehand Flat Draw in Doubles

⑴ Watching the ball: The first step is to start jumping.

⑵ Preparation: Step from left foot to right foot.

⑶ Hit the ball: Step out to the sideline with your right foot and hit the ball.

(4) Return: the first step of return.

5] Preparation: Double jump return.

Nine, the footwork of backhand flat draw in doubles

Figure 26 Footwork of backhand flat draw in doubles.

There are four steps in the backhand draw of doubles:

Watching the ball: the first step is to start jumping.

Hit the ball: hit the ball with your right foot on the ground.

Return: the first step of return

Ready: double jump return

Ten, doubles on both sides of the flat draw footwork.

Draw horizontally on both sides, one forehand step and four backhand steps.

The last step is also the "first step"

Figure 27: The footwork of flat draw on both sides of doubles

Eleven, the footwork of the single kill defense (right)

Take the kill step, five forehand steps and four backhand steps.

Sometimes, the backhand is three steps.

If the ball is close, you can use four steps.

If the ball is closer to the center of the field, you can use four steps.

Fig. 28 Footwork of Single Catch-and-Kill Defense (four steps on the right)

If the ball is far away, it takes five steps.

Photo 29 footwork of single-kill defense (five steps on the right)

Twelve, the footwork of the single-kill defense (left side)

If there is more time or the ball is close, use four steps.

When there is more time, almost 60% of the time is four steps.

Figure 30 footwork of single-player catch-and-kill defense (left four steps)

If there is not enough time, use three steps.

Sometimes you may be late. It takes three steps.

When the ball is close, four steps

Figure 31 footwork of single-player catch-kill defense (three steps on the left)

Thirteen, doubles defensive footwork (opponent’s net attack)

What is said here is the defensive footwork when the opponent saves the ball in front of the net.

Usually there are three steps: preparation, hitting the ball and preparation.

Photo 32 Catch the ball

Fourteen, the footwork of doubles catch defense (pick the high ball)

One look, two dozen, three times, four times, etc.

Photo 33 doubles catch and kill lob

When catching the lob, there are four steps because it is the backcourt ball and there is a certain time.

Look first, then hit the ball, then recover and return to the original position.

Then relax and wait for the next shot.

Photo 34 Catch, Kill and Pick the Golf

Fifteen, the footwork of the high ball (the first: basic footwork)

There are two kinds of high-ball paces in the backcourt.

Here is the first kind, the basic footwork.

There are seven steps. Let’s take a look:

Figure 35 footwork of high-distance ball (the first type: basic footwork)

One look, two aim, three lead, four strike, five look, six view, seven etc.

When the ball comes faster, the last seventh step is the "first step" of the next racket.

Starting from the "first step" and ending from the "first step", so that the next beat can be connected well.

16. Footwork of the high ball (the second type: advanced footwork)

When the opponent hits the backcourt flat and you take the initiative to fight back, then you have to change your footwork.

There are sideways movements and recovery footwork.

The step of recovery can make you return to China faster.

Fig. 36 Footwork of high-distance ball (second type: advanced footwork)

Seventeen, kill the ball footwork

There are basically six steps to kill the ball:

Photo 37 Ball Killing Footwork

When forehand kills the ball, sometimes there can be a slight recovery step.

Photo 38 Ball Killing Footwork

If you need a step to recover, this step must be fast.

If there is not enough time, don’t recover that small step.

After killing the ball, if you need a small step to recover, this step must be fast and small.

If time is not enough, don’t have this small step to recover.
