The Ministry of Industry and Information Technology has issued a new national standard for DC charging of electric vehicles. Will the era of high-power DC charging come?

On September 13th, the Ministry of Industry and Information Technology announced that recently, GB/T 20234.1-2023 "Connecting Devices for Conductive Charging of Electric Vehicles Part 1: General Requirements" and GB/T 20234.3-2023 "Connecting Devices for Conductive Charging of Electric Vehicles Part 3: DC Charging Interface" were proposed by the Ministry of Industry and Information Technology and under the jurisdiction of the National Automobile Standardization Technical Committee.

The new standard follows the current technical scheme of DC charging interface in China and ensures the universal compatibility of new and old charging interfaces. At the same time, the maximum charging current is increased from 250 amps to 800 amps and the charging power is increased to 800 kilowatts. Relevant technical requirements such as active cooling and temperature monitoring are added, and test methods such as mechanical performance, locking device and service life are optimized and improved.

The Ministry of Industry and Information Technology pointed out that the charging standard is the basis for ensuring the interconnection between electric vehicles and charging facilities and safe and reliable charging. In recent years, with the increase of driving range of electric vehicles and the increase of charging rate of power batteries, consumers’ demand for rapid replenishment of electric energy for vehicles has become increasingly strong. New technologies, new formats and new demands, such as "high-power DC charging", are constantly emerging, and it has become a general consensus in the industry to speed up the revision and improvement of the relevant standards of the original charging interface.

According to the development of electric vehicle charging technology and the demand for quick charging, the Ministry of Industry and Information Technology organized the National Automobile Standardization Technical Committee to complete two recommended revisions of national standards, which achieved a brand-new upgrade to the original 2015 version of the national standard scheme (commonly known as the "2015+" standard), which is conducive to further improving the environmental adaptability, safety and reliability of conductive charging connection devices, and at the same time meeting the actual needs of DC low-power and high-power charging.

In the next step, the Ministry of Industry and Information Technology will organize relevant units to do a good job in the promotion and implementation of the two national standards, promote the popularization and application of technologies such as high-power DC charging, and create a good environment for the high-quality development of the new energy automobile industry and the charging facility industry. Slow charging has always been the core pain point of the electric vehicle industry.

According to a report of soochow securities, the average theoretical charging rate of the hot-selling models supporting fast charging in 2021 is about 1C(C stands for the charging rate of the battery system, in popular terms, 1C charging can fully charge the battery system in 60 minutes), that is, it takes about 30 minutes to achieve 30%-80% SOC and the battery life is about 219km(NEDC standard).

In practice, most pure electric vehicles need to be charged for 40-50 minutes and can travel about 150-200km to achieve SOC of 30%-80%. If the time to enter and leave the charging station (about 10 minutes) is added, the charging time of a pure electric vehicle takes about 1 hour and it can only travel on the expressway for about 1 hour.

The popularization and application of technologies such as high-power DC charging will require further upgrading of the charging network in the future. The Ministry of Science and Technology has previously introduced that China has built a network of charging facilities with the largest number of charging equipment and the largest coverage area. Most of the newly added public charging facilities are mainly DC fast charging equipment with a capacity of more than 120kW, and 7kW AC slow charging piles in the private sector have become standard. The application of DC fast charging method has basically been popularized in the field of special vehicles, and public charging facilities have the real-time monitoring capability of cloud platform networking. APP pile finding and online payment have been widely used, and new technologies such as high-power charging, low-power DC charging, automatic charging connection and orderly charging are gradually being industrialized.

In the future, the Ministry of Science and Technology will focus on the key technologies and equipment of efficient collaborative charging and replacement, such as the key technologies of vehicle-pile-cloud interconnection, the planning method of charging facilities and orderly charging management technology, the key technologies of high-power wireless charging, and the key technologies of rapid replacement of power batteries.

On the other hand, high-power DC charging puts forward higher requirements for the performance of power battery, the key component of electric vehicles.

According to soochow securities’s analysis, firstly, the principle of increasing the charge rate of the battery is contrary to that of increasing the energy density, because high rate requires smaller particles of anode and cathode materials and high energy density requires larger particles of anode and cathode materials.

Secondly, high-rate charging in high-power state will bring more serious side effects of lithium evolution and heat generation to the battery, which will reduce the safety of the battery.

Among them, the negative electrode material of the battery is the main limiting factor for fast charging. This is because the cathode graphite is made of graphene sheet, and lithium ions enter the sheet through the edge, so the cathode quickly reaches the limit of its ability to absorb ions in the process of rapid charging, and lithium ions begin to form solid lithium on the top of graphite particles, that is, a side reaction of lithium precipitation occurs. Lithium precipitation will reduce the effective area of the negative electrode for lithium ions to be embedded. On the one hand, it will reduce the battery capacity, increase the internal resistance and shorten the life. On the other hand, the interface crystal will grow, puncture the separator and affect the safety.

Professor Wu Ningning of Rongshengmeng Guli New Energy Technology Co., Ltd. and others have previously written that in order to improve the fast charging ability of power batteries, it is necessary to improve the migration speed of lithium ions in battery cathode materials, accelerate the embedding speed of lithium ions in cathode materials, improve the ionic conductivity of electrolyte, select fast charging separators, improve the ionic and electronic conductivity of electrodes and select appropriate charging strategies.

However, what consumers can expect is that since last year, domestic battery companies have begun to exert their efforts and layout on fast charging pools. In August this year, Contemporary Amperex Technology Co., Limited, the leading company, released the 4C Shenxing rechargeable battery based on the positive Ferrous lithium phosphate system (4C means that the battery can be fully charged in a quarter of an hour), which can realize the ultra-fast charging speed of "charging for 10 minutes and cruising for 400 kilometers". At room temperature, the battery can be charged to 80%SOC in 10 minutes. At the same time, Contemporary Amperex Technology Co., Limited adopts the battery core temperature control technology on the system platform, which can quickly heat to the optimal working temperature range in low temperature environment, even in the low temperature environment of -10℃, it can be charged to 80% in 30 minutes, and it will accelerate at zero speed without attenuation in the low temperature power loss state.

According to Contemporary Amperex Technology Co., Limited, Shenxing rechargeable battery will be mass-produced this year, and it will be the first to be used in Aouita models.

 

And the 4C Kirin fast-charging battery based on ternary lithium cathode material in Contemporary Amperex Technology Co., Limited, after landing the ideal pure electric vehicle first this year, recently landed the Krypton luxury hunting super-run 001FR.

In addition to Contemporary Amperex Technology Co., Limited, among other domestic battery companies, Chuangxin Airlines has laid out two routes in the field of 800V high-voltage fast charging: square battery supports 4C fast charging, and large cylindrical battery supports 6C fast charging. In terms of square battery scheme, Zhongchuang Singapore Airlines provided Tucki G9 with a new generation of fast-charging lithium iron battery and medium-nickel high-voltage ternary battery based on 800V high-voltage platform, realizing SOC from 10% to 80% in 20 minutes.

Honeycomb Energy released the dragon scale battery in 2022. The battery is compatible with all chemical systems such as lithium iron, ternary and cobalt-free, covering the 1.6C-6C fast charging system, and can be mounted on A00-D series vehicles. The designated vehicles are expected to be mass-produced in the fourth quarter of 2023.

Yiwei Lithium Energy released the π system of large cylindrical battery in 2023. The "π" cooling technology of the battery can solve the problem of fast charging and heating of the battery, and its 46 series large cylindrical battery is expected to be delivered in mass production in the third quarter of 2023.

In August this year, Xinwangda Company also told investors that the "flash charging" battery launched by the company for the BEV market can be adapted to 800V high voltage and 400V normal pressure systems. Super fast charging 4C battery products have been mass-produced in the first quarter. The development of 4C-6C "flash charging" battery is progressing smoothly, and the whole scene can last 400 kilometers in 10 minutes.

The Ministry of Agriculture and Rural Affairs and the Ministry of Finance issued the policy of strengthening agriculture and benefiting farmers in 2018.

We will implement the Central Rural Work Conference, the No.1 Document of the Central Committee and the spirit of the National "Two Sessions", implement the rural revitalization strategy, deepen the structural reform of the supply side of agriculture, and accelerate the modernization of agriculture and rural areas. In 2018, the central government will continue to increase investment in supporting agriculture, strengthen the overall integration of projects, and improve the management mechanism for the use of funds. The policy of strengthening agriculture and benefiting farmers with financial priorities jointly implemented by the Ministry of Agriculture and Rural Affairs and the Ministry of Finance in 2018 is hereby released as follows.

First, direct subsidies to farmers

1. Cultivated land fertility protection subsidies. In principle, the subsidy object is farmers who have the right to contract cultivated land. Subsidy funds are directly paid to households through the form of "one card (discount)". The specific subsidy basis, subsidy conditions and subsidy standards shall be determined by the provinces (autonomous regions and municipalities) in accordance with the requirements of the Notice of the Ministry of Finance and the Ministry of Agriculture on Comprehensively Pushing Forward the Reform of "Three Subsidies" in Agriculture (Cainong [2016] No.26) and in combination with local conditions. It is necessary to maintain the continuity and stability of policies and ensure the direct benefits of farmers. Encourage provinces (autonomous regions and municipalities) to innovate ways and means, take the green ecology as the guide, explore the mechanism of linking subsidy distribution with the implementation of farmland protection responsibility, and guide farmers to consciously improve farmland fertility.

2. Agricultural machinery purchase subsidies. The central financial fund covers 137 items in 15 categories, 42 subcategories, and implements open subsidies for machines and tools within the scope of subsidies. The subsidy targets are individuals engaged in agricultural production and agricultural production and operation organizations. Priority should be given to ensuring the machines and tools needed for the production of major agricultural products such as grain, and the subsidy needs for machines and tools to support the green development of agriculture, such as subsoiling and soil preparation, no-tillage sowing, efficient plant protection, water-saving irrigation, efficient fertilization, straw returning and leaving the field, residual film recycling, resource utilization of livestock manure, and harmless treatment of dead livestock and poultry. Provinces (autonomous regions and municipalities) are allowed to select no more than three products to carry out pilot subsidies for the purchase of new agricultural products, focusing on supporting green ecological orientation and applicable machines for hilly and mountainous industries.

3. Producer subsidies. Subsidies for corn and soybean producers were implemented in Liaoning, Jilin, Heilongjiang and Inner Mongolia. The central government will make overall arrangements for subsidies for corn and soybean producers, and the subsidy funds will be paid to producers in the form of "one card (discount)". The specific subsidy scope, subsidy basis and subsidy standard are determined by the people’s governments of all provinces (regions) in accordance with the requirements of the central authorities and combined with local conditions, but the subsidy standard for soybeans is higher than that for corn. Encourage all provinces (regions) to concentrate subsidy funds on advantageous producing areas. In order to promote the reform of the minimum purchase price of rice and protect the income of grain farmers, the central government will allocate a certain amount of subsidy funds to the provinces, and the relevant provinces will formulate specific subsidy implementation plans.

4. Cotton target price subsidy. Continue to implement the cotton target price subsidy policy in Xinjiang and Xinjiang Production and Construction Corps. The target price level of cotton will be fixed for three years, and it will be 18,600 yuan per ton from 2017 to 2019. Subsidy funds are paid directly to the actual cotton growers in the form of "one card (discount)".

The frameless door is handsome, but the experience of opening and closing the door is embarrassing.

Usually, I drive more, and I have to wait until I get on the bus, so I feel very troublesome when I am in a hurry. Therefore, we will pay special attention to how other models are doing in this respect, and always feel that luxury brands should perform better. What is the actual situation? Recently, I went to various houses to spy on the military situation and see how everyone’s frameless frame solves the contradiction between glass and rubber strip.

Why is there a contradiction between glass and rubber strip?

It is impossible to fit perfectly with the door frame simply, so whether it is framed or frameless, the gap between them should be plugged with rubber strips to prevent rain, dust, wind and noise from entering the carriage from the gap. There is a frame because the door frame is hard enough, so the door frame can be pressed directly on the adhesive tape. Frameless glass is easy to shake, and the glass is directly pressed on the adhesive tape, which is easy to leak air and rain at high speed. Therefore, frameless glass generally has two layers of adhesive tape, and the glass needs to be stuffed in the middle of the two layers of adhesive tape.

For this reason, each family has adopted different methods.

Let’s talk about how to open the door first

The traditional glass sinking type is used. When the owner touches the induction module or pulls the keyless entry on the door handle, the glass will drop 2-3cm to avoid the outer sealing strip on the frame. At the same time, there is also a position sensor in it. If it is not lowered to the right position, it can’t be opened. It needs to be pulled again to really open it.

The key of this design lies in the sinking speed of the glass. Like this one, it is not particularly fast, and the door opening action will be somewhat unsmooth. You need to wait for the glass to fall in place before opening the door.

Poor domestic experience

I thought that the world is a family, and the experience of CC should be similar, but after trying it, it is really not the case. CC opens the door in the same way as CC does, but the speed of glass falling is slower than that. Even if it is slow, CC seems to castrate the glass position sensor, and the glass can be pulled open without being completely lowered.

This is more embarrassing. If you pull it away quickly, the glass will almost scrape the outer layer of the car frame, and such deformation will accelerate the aging of the rubber strip for a long time. Moreover, when the door is closed, the rear door glass of CC will clip the outer rubber strip at the end between the two rubber strips, leaving a gap the size of a little finger. I am more worried about whether the rain will flow in through the small hole. The owner of CC can leave a message to discuss with us.

Being a group has a good experience.

After experiencing several brands, I think the best experience is that although they belong to the same group, they all use sunken structures. However, the falling speed of the glass is really very fast, which brings a nearly framed smooth experience without scraping the rubber strip. Moreover, it may be that you have enough confidence in your own speed, and the starting time of sinking is different. It starts to descend at the moment when you pull the door handle, thus avoiding the problem of accidental touch.

Why do you want to mention this matter by mistake? I have met it more than once. When the car washer was putting on foam, he accidentally touched the sensor on the door handle, dropped it a little, and the foam flowed in …/(ㄒㄒㄒ)/~ ~

The solution is the simplest and rudest.

Most manufacturers choose glass sinking structure for frameless structure, which only means that this mechanism is too complicated and it is a waste of life. The simplest and rudest way is chosen, which narrows the outer rubber strip directly, and designs a cutting angle with an inclination of 45. At the same time, the glass is pushed out directly against the cutting angle.

For this solution, the more violent the door is, the better, because if it is closed slowly, the glass will get stuck outside the outer rubber strip and not be squeezed in. This scheme is also very close to the box, but the action needs to be rude.

Yes, the combination

Then a comprehensive solution is chosen. On the one hand, the sinking solution is adopted (not as fast as the image), on the other hand, the outer rubber strip is narrowed, the descending distance is reduced, and the smoothness of door opening action is improved; And if necessary, if you are impatient, you can also rub the rubber strip to open it like this.

However, this seemingly perfect design is not perfect, and there is still a certain chance that the door will rub against the outer rubber strip when opening the door during the live experience.

If you also drive a frameless car, you might as well talk to us about any interesting phenomena when your car opens and closes the door.

Lei Jun: Xiaomi’s pursuit of cost performance does not mean cheap pricing. Friends should not mess with us.

Lei Jun shows Xiaomi 9.

"This is the last flagship model of Xiaomi brand below 3,000 yuan. In the future, Xiaomi brand will focus on the mid-to high-end market."

On February 20th, Lei Jun, founder, chairman and CEO of Xiaomi Group (01810.HK), unveiled Xiaomi 9, the annual flagship mobile phone, at the Beijing press conference.

Although Lei Jun has spoiled the new machine a week in advance, so that netizens are psychologically prepared for the price of the new machine, Lei Jun said that he is still worried that the pace is too big, fearing that rice noodles can’t be accepted. "I discussed with several other executives for two days and finally set the price at 2999 yuan." However, according to the reporter’s understanding, this price is still more expensive than Xiaomi 8, 300 yuan, and it is 50% more expensive than the iconic 1999 yuan pricing of this series earlier.

In an interview with The Paper and other media after the meeting, Lei Jun said that Xiaomi’s pursuit of cost performance is not equal to cheap pricing. "Cost performance is the same performance, the cheapest price and the strongest performance, not the absolute price."

"When the average price of domestic mobile phones was only six or seven hundred yuan, Xiaomi’s mobile phone came up to 1999 yuan, which was absolutely high-end in that era. Later, many rice noodles asked us to be a Redmi brand, but when we achieved the price of seven or eight hundred, we were smeared by some water army and friends, labeling us and saying that we sold cheaply. " Lei Jun said.

During the interview, Lei Jun also responded to the recent Xiaomi focus issues such as ending flat management, Qualcomm’s true and false starting, double folding screen technology, and the establishment of China District.

Responding to the price becoming more expensive: "The price/performance ratio has made great contributions to Xiaomi, but now it is bound."

Regarding the price issue, Lei Jun said, "This is the most tangled. The cost-effective advantage has made great contributions to the rise of Xiaomi brand, but now it has become a constraint."

According to reports, the cost of Xiaomi 9 has been greatly improved: on the one hand, the price of components has generally increased; On the one hand, more advanced technologies and processes have been introduced. For example, the world’s first Qualcomm Snapdragon 855 is 20% more expensive than Snapdragon 845, Sony camera module is 30% more expensive, and the screen fingerprint is twice as expensive as the rear fingerprint; On the one hand, Xiaomi’s R&D investment is also increasing. In the first three quarters of 2018, R&D investment exceeded 4 billion yuan.

"Now the pile of mobile phones is too embarrassing. I remember that the earliest Xiaomi 1 had only one camera, and there was no front camera. Up to now, the front camera has three lenses on the back and a macro camera with a screen fingerprint of 5um. In fact, there are five cameras on the whole mobile phone. These five cameras not only cost money, but also occupy an area. The upper and lower areas account for more and more, and there are more and more functions. So now the cost of mobile phones is because the performance of mobile phones is getting stronger and stronger, and the cost of mobile phones is getting higher and higher. " Lei Jun said.

In 2018, the overall smartphone market declined and the competition became increasingly fierce. At the end of last year, Xiaomi Group split the Redmi (Redmi) brand, forming two brands with different positioning: Redmi and Xiaomi. Redmi is obsessed with cost performance, while Xiaomi pursues the ultimate experience on the basis of cost performance.

"Make the Redmi brand independent, let the Redmi brand adhere to high quality and extreme cost performance, and let others dare not compete with Redmi in terms of cost performance. The Xiaomi brand is not prepared to compete with Redmi. On the Xiaomi brand mobile phone, the function of the mobile phone will become stronger and stronger. Sometimes we don’t even consider whether there is the ultimate cost performance. We only ask if there is an ultimate experience, so its priority is different. " Lei Jun said.

However, Lei Jun stressed that Xiaomi Group will not pursue high premium and high gross profit, and Xiaomi will still sell it at a good price, and the high premium millet on the hardware will not earn it. He reiterated that the comprehensive profit rate of Xiaomi hardware will never exceed 5%.

Shenwan Hongyuan Electronic Team believes that in the fourth quarter of 2018, the shipment of Xiaomi series mobile phones is about half of that of Redmi series mobile phones, while the shipments of the two series are equal. In 2019, it is expected that emerging mobile phones will continue to grow, while mature markets will face consumption upgrading. The key to China’s flagship mobile phone is to increase the sales of models above $300 (about RMB 2020). The separate operation of Xiaomi and Redmi brands will help break through the market of more than $300.

The market believes that behind the price increase of mobile phone manufacturers such as Apple, Huawei and Xiaomi, in addition to the increase in raw material costs and R&D costs, the sales volume has declined, and it is necessary to increase the selling price to make up for it.

Lei Jun released Xiaomi 9 and announced Roy, a member of TFBOYS, as the image spokesperson.

Denying that there is no flat management: "Some people say that Lei Jun has changed, but I have not changed."

A few days ago, Caijing magazine reported that Xiaomi bid farewell to the once proud flat management. Today, Xiaomi’s internal titles are roughly divided into Commissioner-Manager-Director and Vice President and above, with 10 levels, from 13 to 22. The level of the Commissioner is about 13, the manager is about 16 to 17, the director is about 19 to 20, and the vice president is about 22.

In the past, Xiaomi had only three levels: co-founder-department head-employee, and pursued the policy of no punching and no KPI. Caijing magazine quoted an employee of Xiaomi as saying that Xiaomi has to punch in at work at present, and attendance is particularly strict after the Spring Festival this year, and the department also has KPI.

"I was a little embarrassed to see that title, saying that Xiaomi has changed and Lei Jun has changed. In fact, I have not changed." Lei Jun responded that all Xiaomi’s senior partners are in the front line and still adhere to ultra-flat management. "Including the Weibo conference in the past week, I wrote it myself. The workload in the past week far exceeded everyone’s expectations."

Lei Jun said that at present, Xiaomi has 23,000 employees, and the human resources system is setting the talent level to facilitate further talent sorting and training and upgrading in the future. "If these management upgrades are not made, it will be difficult for Xiaomi to evolve into a team that manages more than 100,000 people in the future."

"This year, Xiaomi will invest heavily in the training plan of the cadre team, and talent sorting can also better adopt different levels of training methods for different levels of cadres. There are also engineers and experts who should provide what kind of benefits and incentives to sort out these things. I think it is a very important part of Xiaomi’s overall management upgrade. " Lei Jun revealed.

Establish AIoT strategy committee: "If you don’t increase AIoT investment, it is very likely that your opponent will catch up."

At the beginning of this year, Xiaomi launched the dual-engine strategy of "mobile phone +AIoT", which listed AI (artificial intelligence) and IoT (Internet of Things) as the strategic direction to go hand in hand with mobile phones, and proposed to invest 10 billion yuan in the AI+IoT field in the next five years.

"In the eight years of early entrepreneurship, Xiaomi’s core strategy was to connect all devices with mobile phones as the center. However, with the rise of a series of products such as AI technology and small love speakers, as well as our rise in various fields of TV and home appliances, we have unconsciously become the world’s number one in the field of AIoT. " Lei Jun said.

"Opponents are catching up. If we don’t increase our investment in AIoT, it is very likely that we will be caught up by our opponents. Moreover, AIoT is also the most important trend in the future development. Therefore, after repeated discussions, Xiaomi’s senior management felt that we should increase the investment in AIoT. " Lei Jun revealed that at present, Xiaomi has set up a strategic committee of AIoT, increased special investment, and continuously maintained investment to ensure our advantages in this field.

Lei Jun also revealed on the same day that the dual-engine strategy is specifically "1+4+X": mobile phone+(small love speakers, routers, televisions, notebooks)+ecological chain products. Among them, Xiaomi AI smart speaker "Little Love Speaker" has become a strategic hub product of AIoT.

On the same day, Xiaoai touch screen speaker was released, and the public beta was opened on February 28. However, because IoT is still in the early stage of the market, there are still many immature places. Lei Jun also called on all rice noodles to be more patient.

After the conference, users experience Xiaomi 9.

What is a "real starter": "Qualcomm risks offending friends and businessmen to forward our Weibo"

At the press conference, Lei Jun said that Xiaomi 9 won the world premiere of Qualcomm Snapdragon 855, and called it a "real premiere", which was the first time that Xiaomi replaced Samsung to win the world premiere of Qualcomm’s flagship chip.

Lei Jun told reporters after the meeting that it is very difficult to launch a flagship processor. In fact, mobile phone manufacturers need to cooperate with Qualcomm in research and development. "Almost two years ago, we set up an R&D center in San Diego, USA. From the establishment of the Snapdragon 855 project, we discussed it with Qualcomm. We reviewed and tracked every stage in the middle, and followed up every generation after getting the engineering samples. By January, we were ready for mass production."

It is reported that Snapdragon 855 is the biggest upgrade of Xiaolong 800 series processor in recent years, adopting 7nm process, brand-new Kyro 485 architecture, the highest frequency is 2.84GHz, the single-core performance is improved by 45% compared with the previous generation, the GPU is improved by 20%, and the fourth-generation AI engine has three times the performance of the previous generation.

"Why write a real starter? Some friends make some samples and make several prototypes (just say it’s the first launch), but I had this prototype four or five months ago. Making a demo prototype is different from making millions or tens of millions. What we are talking about today is mass production, which is also approved by Qualcomm, not for gimmicks. Why did Qualcomm risk offending friends and businessmen to forward our Weibo twice? Because they really recognize our efforts in the high-end flagship. " Lei Jun said.

Establishing China District: "If you want to compete with friends in China market, the difficulty lies in improving efficiency."

In December 2018, Xiaomi announced that it would strengthen its investment in the China market, reorganize its sales and service department into China District, and appoint Wang Chuan, senior vice president of the Group, as the president of China District, reporting to Lei Jun.. In the previous adjustment in September, Wang Chuan was appointed as the chief of staff of the newly established Group Staff, assisting Lei Jun in formulating the development strategy of the Group and supervising the strategic implementation of various business departments. Previously, Wang Chuan was in charge of Xiaomi TV business.

Lei Jun said that if Xiaomi wants to compete with friends in the China market, the difficulty is that it can’t sell at such an expensive price, and it has to work hard to improve efficiency. "I hope Mr. Chuan (referring to Wang Chuan) will lead the team to develop a product called New Retail with the spirit of making products and doing research and development. How to do high-end, how to do experience, how to cooperate with offline retail and online e-commerce, and promote product efficiency, demonstration efficiency, sales efficiency and overall feeling. "

Wang Chuan told reporters that after two months in charge of China District, he saw two trends. First, mobile phone manufacturers are doing globalization and multi-channel, and Xiaomi will maintain its advantage in e-commerce. Second, it will further penetrate offline and let more users buy good products. This year, it will increase investment in this area.

"Wang Chuan led China District for two months, which has made me see the great changes in China District. He is not doing simple sales, especially with the Xiaomi series of mobile phones to promote product transformation in China. " Lei Jun said, for example, the release of Xiaomi 9 this time has made great innovations in store layout. Wang Chuan has designed many scenes, such as being able to experience dark light shooting in a small darkroom.

Xiaomi and Redmi are independent brands.

Redmi Redmi independence: "Cheap should be based on high quality, and friends should not make trouble in a cost-effective coat."

In January this year, Xiaomi announced the opening of the dual-brand era, and announced that Redmi Redmi was upgraded to an independent brand. As an e-commerce brand, Redmi Redmi will set up an independent company to operate. In the future, Redmi Redmi and Xiaomi are both brother brands under the same group and competitors in the same market.

"In the fourth quarter of last year, Xiaomi (brand sales) accounted for the vast majority in China. Relatively speaking, we ignored Redmi, so we decided to change the name of Redmi to Redmi at the end of last year, which was led by General Manager Lu (former second-in-command of Jinli). The whole company will increase its investment in Xiaomi, but we can’t ignore the great significance of Redmi in popularizing smart phones." Lei Jun said.

"Why does Redmi put high quality first? Because cheap is the original sin, cheap can also be based on high quality. You sell 999 yuan, and people will not trust you as soon as you come up. If you don’t do a good job in quality, just do it cheaply, and everyone will think you are low as soon as you come up. Last time I said, friends have nothing to do with cost performance. Don’t always make trouble with us in a cost-effective coat. "

Respond to the double folding screen mobile phone: "After two years of tossing, there is no mass production, and each has its own technology."

On January 23, Lin Bin, president of Xiaomi, first exposed Xiaomi’s double folding mobile phone on Sina Weibo, and was bombarded by Fan Jun, vice president of Rouyu Technology who specializes in folding technology: "A mobile phone assembly company with no screen core technology patent and production line, buying someone else’s concept flexible screen and concept that has not been mass-produced, does it mean that it has conquered the flexible folding screen technology?"

"This is definitely ignorance of the mobile phone industry." Mr. Lei responded that the folding screen was not made by Xiaomi, but if the folding screen is made into a product, the workload inside is unprecedented. The double folding screen is definitely the first of Xiaomi.

"We made the folding screen from the flexible screen, and it has been tossed for two years, so that everyone can see that the folding screen can be doubled. I keep telling them, do you have to be an engine to make a car? Is there no technology in the whole factory without making engines? Isn’t this ridiculous? Can’t you make an airplane if you don’t make an engine? As we all know, the engines on Boeing aircraft are all GE’s. Everyone innovates in different fields, component manufacturers innovate in component technology, and whole machine manufacturers innovate in system integration, each with its own difficulties. " Lei Jun said that this is his own indignation.

"Head companies have invested a lot of money in research and development, and they are all pre-researching various projects. Since last year, I don’t know who took the lead, that is, all the pre-research technologies began to be released, which drove us crazy, but none of these pre-research projects can be mass-produced. In these two days, the TOF (a scheme TOF(3D deep camera shooting) that quarreled with each other was also done on Xiaomi MIX3. Today, the competition in mobile phone technology is fierce, and we have been investing a lot of money in pre-research. " Lei Jun said.

How does a famous agricultural book guide our basic necessities of life?

Beginning of autumn, which has just passed, obviously failed to send away the arrogance and summer heat for several days. It has not slackened in the dog days, and it is still full of power. People can’t help feeling how people spent the seventh month of the lunar calendar in ancient times without air-conditioning fans. Today, we will take a look at how the ancients arranged their work through Qi Min Yao Shu, the earliest and most systematic ancient agricultural book.

"Qi Min Yao Shu Jin Shi", [Northern Wei Dynasty] Jia Sixie wrote a proofreading of Shi Shenghan.

Qi Min Yao Shu says that by July, wheat fields and rice fields no longer need to be cared for, and the main farming activities have come to an end, while the busyness between villages has just begun.

The first is to farm and raise silkworms. During the Wei, Jin, Southern and Northern Dynasties, there were many mountains and marshes waiting for land reclamation. People need to take advantage of the hot weather to remove weeds, dry them in the sun, and then set them on fire. Otherwise, it will be too late to do it when planting next spring.

In Yongjia County in the south (now Wenzhou, Zhejiang Province), there is a famous "eight generations of silkworms", which means that there are eight batches of silkworms that can be kept in a year. At the end of July, there was a kind of silk silkworm named "Hanzhen", which was beginning to spin silk and form cocoons, so we need to pay more attention to it.

[Song] Liu Songnian’s "Silkworm Things"

July is also a harvest month. At that time, there were many kinds of rice. There were as many as 24 kinds of northern rice recorded in Qi Min Yao Shu, and there were only 14 varieties of japonica rice. At this time, cicada-singing rice is ripe, and this kind of rice can also grow in the north. In Yu Xin’s poem, "cicada-singing rice in June, golden keel canal" refers to this kind of rice.

After harvesting rice, you should also worry about vegetables such as cucumbers, lettuce and radishes in the vegetable fields. If you have your own cattle and cars, you can cut them all down and transport them to the city for sale on the sixth and fourteenth day of July. These two dates are very strange, presumably because there is a "festival" the next day, and the city needs to consume more vegetables. On the seventh day of July, it is called "Melon and Fruit Festival". On this day, girls will offer melons and fruits to "Tiansun" (Weaver Girl) and "beg for cleverness". July 15th is the Mid-Autumn Festival, and the Buddhist "Bonsai" will be held on this day, and many vegetables will be needed for Buddhist purposes.

"Annotation of Agricultural Administration Encyclopedia", [Ming] Xu Guangqi wrote a supplement to Shi Shenghan’s annotation Shi Dingfang.

Some vegetables can be planted at the same time as they are sold. For example, the seeds are sown in early July, and three liters of seeds are sown on an acre, which can be eaten by a family for a long time. Even from summer to August, it can be planted. Those planted in early July are used to pickle pickles, and those planted after the summer heat can be used as dried vegetables.

After the mid-autumn, that is, not long after beginning of autumn, you can plant some winter sunflower. It would be better if mung beans were planted in the fields in June. In July, when you turn over the soil with a plow, the land will be as fat as the one with manure, and the effort of picking manure will be saved. In addition, there are garlic, onion, leek, coriander, alfalfa, mustard, canola, etc. for farmers to sow in July.

Xu Zhong’s Notes on Fan Sheng Zhi’s Book Today "The Grass in the South", by Shi Shenghan.

People who plant trees and flowers also have their deadlines in July. Although willows are often planted in spring, in June and July, they are planted with twigs from the spring of that year, and they grow as if they were growing at double speed.

Cypress trees can be cut for use all year round, but Qi Min Yao Shu tells us that other miscellaneous trees in the mountains will be infested with insects if they are not cut in April or July, so it was also a common sight to lift an axe into the mountains in July.

As for planting flowers, it’s not for adding romance to Chinese Valentine’s Day. Safflower can be used as dye and rouge. Qi Min Yao Shu also left a detailed record of rouge and lip fat, and said that the "late flower" planted in May, picked in July and half, has the most vivid color and is not easy to fade, which is better than that planted in spring.

Rouge in Qi Min Yao Shu

Bread is the staff of life. In addition to farming, July has become a good time to process non-staple food in a year because of the hot weather. For example, making koji is the best in July. Jia Sixie has collected many kinds of koji-making methods, such as Shenqu Millet Rice Wine Method, Sanhu Wheat Qu Method, Hedong Shenqu Method, Bailao Qu Method, Qinzhou Spring Wine Qu Method, and Millet Furnace Wine Method, among which the seventh day of July is a day worthy of attention.

On the fourth day of July, tidy up the music room, prepare the plaque and bracket properly, and adopt clean and good moxa.

On the sixth day of July, "lick the five grains", prepare grinding tools, and lick the five grains grinding tools.

On July 7th, we began to make distiller’s yeast.

Even vinegar is made on July 7th. There is a way to make vinegar from barley, which is very strict on time. It is required to be made on July 7. If you don’t have time to do it on that day, you should be prepared to collect it-take water on the seventh day and make it on the fifteenth. If you don’t make it in these two days, you won’t be able to make it in the rest of the day.

Mural "Vinegar Filter"

The eating habits of nomadic people, such as dairy products, are also recorded in Qi Min Yao Shu. For example, cheese is baked in the sun first, and after the milk skin is formed on the cheese, the floating surface is uncovered; Bake again, then uncover. When the oil runs out and no skin comes out, stop the fire and the cheese will be made.

Qi Min Yao Shu also reminds people to pay attention to the season when eating from the perspective of food hygiene. Such as silk, you can’t eat it until the end of July, September and October, because snails and worms are stuck on it at this time. The worm is so small that it is connected with the water shield that it is invisible to the naked eye.

Compilation and collation of convenient maps, edited by Shi Shenghan and Kang Chengyi by Kuang Kun [Ming].

There is a strange recipe for getting rid of diseases and disasters that attracts the most people’s attention-"On the seventh day of the first month, on the seventh day of July, men swallowed seven adzuki beans and women swallowed fourteen, but they were disease-free; Make the epidemic disease not infected. " On the seventh day of the first month and the seventh day of July, people have the custom of eating adzuki beans, which can keep them from getting sick all year round and keep the plague from spreading.

What activities do the scholars have? The answer is to print books. The seventh day of July is a good time to print books. As for why you choose this day to print books, and what matters need attention, Qi Min Yao Shu records it in great detail:

"Hot and humid in May, moth will be born, and those who don’t stretch their books in summer will be born with worms. After may 15 and before July 20, it must be relaxed and rolled up three times. When it needs to be sunny, it will be in a cool place under the big house, and the sun will not be seen. "

"Exposing books every day makes them colorful. Hot coil, the worm is very fast. Rain moistens the air, so it is especially necessary to avoid it. If you are cautious, it will take hundreds of years. "

It rains in midsummer, and the rustic steam is hot. If the book is not dried in the hot and humid summer, it is easy to give birth to moth. During the sixty-five days from May 15th to July 20th, books can be preserved for hundreds of years if they are spread out under a big house with cool wind and no direct sunlight. If the sun shines directly, the color of the book will darken; Roll up while it’s hot, and worms will grow even faster; In addition, we should avoid the humidity in rainy days. Therefore, it is a good choice to avoid the long plum rain and the rush of the field, and the seventh day of July is sunny.

Guang Ji at the age of [Song], edited by Chen Yuanliang and Xu Yimin.

In addition to drying books, all kinds of complete sets of lacquerware at home should be taken out and dried once in June and July, even if they are not used all summer. Such as lacquer paintings, lacquer boxes, lacquer pillows, etc., when it rains in the middle of July, it is wrapped around your fingers with cloth and wiped until it is fully heated, so that the glue will not move and become easy, and the utensils are naturally bright, clean and durable.

By the end of July, the above work will be finished one after another. During the period from the summer to the autumnal equinox, you can consider washing old clothes and adding new clothes to prepare for the arrival of late autumn.

Modern Interpretation of Qi Min Yao Shu (China’s classic translation series)

[Northern Wei Dynasty] A Textual Research on Shi Shenghan Written by Jia Sixie

Traditional horizontal arrangement

32 open paperback

brief Introduction of the content

Qi Min Yao Shu, written by Jia Sixie in the Northern Wei Dynasty in the 6th century A.D., is the earliest and most complete comprehensive and systematic agricultural encyclopedia in China, including agriculture, forestry, animal husbandry, sideline production and fishery, and also the earliest and most systematic agricultural masterpiece in the world. The book is rich in content, covering a wide range, including cultivation techniques of grain crops, vegetables, fruit trees and trees, processing, storage, brewing and cooking of agricultural and sideline products, as well as descriptions of cash crops and foreign products, which reflects the agricultural scientific knowledge accumulated by working people in China before the sixth century and is also a treasure house of life knowledge of the ancients.

Qi Min Yao Shu Jin Shi is the first relatively complete annotated version of this book, which was compiled by Professor Shi Shenghan, a famous agronomist, and became famous at home and abroad after its publication. This book has done a lot of collating work on the text, checking and proofreading Ming manuscripts, gold notes and several Ming and Qing engravings, punctuating and segmenting, and making detailed comments and translations, so that this ancient book, which is difficult to read in ancient Austria, can be read. This reprint, on the basis of the original, corrects some editing and proofreading mistakes to contribute to the readers.

Brief introduction of the author

Jia Sixie, an outstanding agronomist in ancient China, was a native of Qingzhou (now Shandong) in the Northern Wei Dynasty. He was once the satrap of Levin. In the late Northern Wei Dynasty, he wrote a masterpiece of agricultural science and technology, Qi Min Yao Shu, which is the earliest and most complete comprehensive systematic agronomy encyclopedia in China, including agriculture, forestry, animal husbandry, sideline production and fishery, and also the earliest and most systematic agronomy masterpiece in the world.

Shi Shenghan (1907-1971), a native of Xiangtan, Hunan Province, is a professor at Northwest Agricultural College, an agricultural historian, an agricultural educator and an expert in plant physiology. In his later years, he devoted himself to sorting out and studying China’s ancient agricultural scientific heritage, and successively completed more than ten kinds of works, such as Qi Min Yao Shu Jin Shi and Nong Zheng Quan Shu Jiao Annotation. He was one of the important founders of agricultural history in China.

As a joint venture veteran, who is more suitable for you than Nissan Sylphy?

Volkswagen and Nissan, as two popular compact cars, occupy a considerable position in the market. However, after in-depth comparison, it is not difficult to find that there are some differences between the two cars. Next, this paper will analyze in detail who is more cost-effective from multiple dimensions.

First of all, from the design point of view, LaVida and Sylphy are both classic and dignified products, focusing on an all-age adaptation. Of course, for young people, both of them are not very trendy, mainly highlighting a stable and stable. The interior is the same. The interior of the two is neither luxurious nor technological, but it is very practical and convenient, and it is also suitable for blind operation. It is still a stable orientation.However, from the perspective of space, LaVida is a little more spacious, and comfort is the specialty of LaVida, which is much better than LaVida. However, many people say that Sylphy’s seat is too soft and comfortable for a short time, but there is no sense of package and support after sitting for a long time, which makes people feel a bit contradictory.

In terms of chassis, both of them adopt McPherson+torsion beam structure, which is very common in the same class products, which is considered as reactive power, and can’t be compared with the multi-link rear suspension of many independent models. In terms of chassis adjustment, the two cars show completely different temperament, LaVida is full of toughness and sporty feeling, at least in this price range, it is a product with good control, and the effect of filtering vibration is not bad, belonging to a stable and comfortable model. Sylphy is softer than LaVida, and it is a completely comfortable product. As for the control, it can’t be said that there is nothing at all, but it is almost the same as nothing.

As for the power, LaVida is equipped with a low 1.5L natural inhalation and a high 1.5T dry dual clutch. It is not tiring to work with high and low, and this 1.5T combination is really perfect. Those problems are basically gone before. Of course, if the budget is not enough, the power of 1.5L self-priming is really a bit meaty and can only be endured. Sylphy, the fuel version of 1.6L self-priming +CVT is familiar to everyone, and the fuel-saving model +12 seconds Buddha system breaks 100. There is also an electric drive version equipped with a gasoline engine and a motor with considerable torque, which is fuel-efficient and strong. It can be said that it is the best choice for the network car, and it feels good at home. The specific principle is not developed here, which is more complicated. In short, the gasoline engine mainly generates electricity, and then the vehicle is driven by electricity.

In terms of technology configuration, LaVida is slightly higher as a whole, but both sides actually don’t pay much attention to the sense of technology, and the height is not much higher. The main reason is that the high-end models have more intelligent driving related equipment such as adaptive cruise, and the whole is a combination of practical schools.

On the whole, the comprehensive configuration of the Sylphy electric drive version is relatively cost-effective, followed by LaVida. The low allocation of both parties is very simple, mainly for commercial purposes and unit cars, and the home is a bit too stretched.

All in all, in our opinion, the comprehensive cost performance of Sylphy electric drive version is the highest, and it is good to start and stop without endurance anxiety, that is, the price is a bit high, and the top match can be bought. If only the fuel version is considered, the cost performance of LaVida is obviously higher than that of Sylphy, especially the driving experience and configuration of the 1.5T version are very good, and the discount is also very beautiful. However, if you are a drip driver, then Sylphy is definitely more suitable. After all, it is fuel-efficient, comfortable and cheap.

Hit the water in the middle stream: artistic representation and innovation of party history

  To celebrate the 100th anniversary of the founding of the Communist Party of China (CPC), a major revolutionary historical TV series "Hit the Water in the Middle Stream" highlights the great initiative, struggle and dedication of communist party people, and focuses on the purity of communist party people’s initial heart, the truth of doctrine, the firmness of faith and the beauty of personality. The play was produced by the Central Radio and Television General Station, produced by the TV Drama Documentary Center of the General Station and produced by China TV Drama Production Center Co., Ltd. After it was broadcast in the prime time of CCTV’s comprehensive channel at the main station, it triggered a hot discussion in the society and the communication effect was obvious. According to the data of CSM national network, the highest viewing share of "Mid-stream Hit Water" is 3.32%. On the platform of Iqiyi, "Mid-stream Hit Water" ranked third in the hot list of historical dramas. The audience and netizens have a good reputation and are known as "the pathfinding journey of revolutionary pioneers and a vivid teaching material for learning the history of the party." Analysis of its reasons, in addition to the grand structure, well-made, rich characters, there are many internal inevitable factors.

  First, aim high and focus on the initial heart.

  No great cause can be short of ideals and beliefs that run through it. The Communist Party of China (CPC) led the people from poverty and weakness to prosperity and strength, fulfilling the dream of several generations of China people since 1840 — — National independence, national prosperity and people’s happiness. The core of communist party’s success is, as always, to practice the concept of "seeking happiness for the people of China and rejuvenation for the Chinese nation". Focusing on this concept, Midstream Hit the Water uses a variety of innovative artistic expressions to show the Communist Party of China (CPC)’s century-long glorious course from birth, development to continuous growth, leading the people of China to forge ahead courageously.

  Looking at "Hit the Water in the Middle Stream", people can see that the Communist Party of China (CPC) people not only inherited and developed Marxism, but also constantly strengthened and sublimated their "initial heart". "Do not forget your initiative mind" is an important proposition put forward by the Communist Party of China (CPC) in the new era, but this proposition is by no means abstract. It is rooted in every party member’s life choices and actions. From this theme work, we can see that it is also rooted in the daily work and life of TV and literary and art workers. Only by abandoning snobbery can we aim high; Only the initial resonance can resonate. Because of its accurate position and high vision, it is vivid and tough, and full of strong appeal. It not only provides rich spiritual and cultural food for the people, but also consolidates the dominant position of socialist culture in silence.

  Second, artistic creation, the courage to innovate

  Successful TV dramas with revolutionary historical themes must be derived from and loyal to history, but they must transcend history and sublimate their spirit, and make moderate artistic creation on the basis of reality, which just reflects the artistic accomplishment and political height of the creative team.

  Red revolutionaries can be seen in every episode of "Hit the Water in the Middle Stream". In many chapters describing revolutionary figures, there are many plots that increase the emotional color of the creative team. On the basis of respecting history, many unknown storylines are excavated and the psychological descriptions of the creators are superimposed. For example, when Mao Zedong saw the Chinese version of the communist party Declaration for the first time, he was so excited that he couldn’t sleep at night. When he saw the wonderful place, he couldn’t help stamping his feet and praising it, which affected the sleep of the downstairs tenants several times. This interpretation depicts the pure passion of devout revolutionaries and the ecstasy when they see the way forward, which has strong political vitality and artistic appeal.

  Hit the water in the middle stream presents the historical essence to the audience artistically, and realizes the dialectical unity of "historical truth" and "artistic fiction" Under the narrative principle of "big things are not empty, small things are not limited", the innovative media products systematically sort out the timeline of historical events, and the plot is full of chronological texture. For example, many historical events such as the diplomatic failure of the Paris Peace Conference, the May 4th Movement and the Zhang-Zhang Movement were successively restored, among which a series of events such as progressive students studying in France, the establishment of the Enlightenment Society by Zhou Enlai, Li Dazhao’s dispute with Hu Shi, and Yang Changji’s death were interspersed. Many audiences were moved by the vivid portrayal in the play, and sincerely commented that "this play can be said to have summed up that period of history in an all-round way", "the stories of revolutionary ancestors are worth understanding, and the TV series truly reflects the original appearance of history" and "there are many events without chaos, as if they were brought into the historical situation". Such historical re-creation, from the creator himself, is a sublimation and improvement again and again; For the audience, it can more easily arouse emotional resonance, thus enhancing the communication effectiveness of the main melody melody literary works and creating a spiritual atmosphere of strong confidence, warmth and gathering people’s hearts.

  Third, see the big from the small, and moisten things silently

  How to tell a good story about major revolutionary history is a realistic proposition faced by the propaganda ideological and cultural front, and it is also an innovative topic that the majority of creators must keep up with the changes of the times. In a revolutionary historical drama, it is not easy to keep pace with thoughts and stories, and the details and connotations complement each other.

  Hit the water in the middle stream blends sublimity with daily life, mission with human nature, and moistens the ideal of the red revolution and the indomitable and down-to-earth spirit of struggle with silent artistic means. Starting from a small place and setting off the lofty revolutionary ideal with simple and touching details, the play can not only deeply impress the ordinary audience, but also make people sincerely pay high respect to the leaders. The main characters in the film are not only ambitious and self-sacrificing talents for saving the country, but also good sons and daughters of China with flesh and blood, affection and righteousness. For example, Yang Changji, as a modern ethicist and educator who accepted the dual influence of Confucian traditional culture and western culture, can be said to be a very discerning Bole. He once predicted: "Mao Ersheng and Cai Ersheng will inevitably be the pillars of China in the future." His thoughts and personality had a profound influence on Mao Zedong. Yang Changji died, and Mao Zedong, as a revolutionary who was concerned about the country and people, made a wreath of snow to pay homage to his father-in-law. This seemingly ordinary scene has made countless people cry. It is these well-intentioned artistic designs that vividly depict the touching images of the party’s leaders and predecessors "seeking happiness for the people of China and rejuvenation for the Chinese nation", and prove from the depths of human nature that the Communist Party of China (CPC) has strong vitality and continues to be supported by the people.

  "Hit the water in the middle stream" is a representative of the outstanding works of the main theme that stimulates positive energy and promotes truth, goodness and beauty, and has realistic value and historical influence that cannot be underestimated. The times change and the spirit is eternal. It is more and more excellent works like this that convey the accumulation and nutrition of the Red Revolution to the broad audience silently, which not only plays an important role in ideological education, but also provides a vivid creative model for propaganda and ideological front.
