Didi has recently been quite "attentive", launching a complain program of "Chattering Didi", which is self-deprecating, self-deprecating, mutual tearing, "red-faced sweating", which has attracted a lot of laughter and applause. The president, Ms. Liu Qing, personally "went to the grassroots" and worked as an operator to respond to users’ complaints. The funny and warm feelings are combined, and while adding points to Didi, there are also voices of doubt.

In the public video, Liu Qing asked Didi executives to go to the first-line experience operator when they were promoted. From her personal experience, the professionalism is debatable. Grassroots customer service is a variety of cooperation work. If this can represent Didi’s customer service level, it will actually increase users’ concerns. We can’t say this is a "show", but professional people do professional things. Even if executives come to answer the phone as customer service, can they reap real problems? The key is that on-the-job customer service strictly implements relevant systems.

Look at the complain link again. The selected roles are talk show stars, luxury car stars, drivers, and product manager representatives. Is this user sample down-to-earth and can it represent the voice of the majority? In response to specific questions: the price increase of taxis, take "riding a bicycle will pass by the fruit store to buy expensive cherries" to prove that taxis are more cost-effective; the big data kill problem, the response is "You have only driven a few times, are we familiar with you?"; the estimated price error problem, take the black car price "darker" as a comparison; the customer thinks that the navigation detours far and insists on his own direction, which boils down to the passenger’s "will to ride a bicycle".

For another example: passengers can’t get a taxi, and the product manager attributed the root cause to limited transportation capacity, "I can’t do it". The problem is that behind the limited transportation capacity, is it a regulatory problem in various places? Or is it a problem with the platform? In a business, if there is demand, there will be supply. Who doesn’t make money? If the reflection is not deep, the problem is difficult to solve.
　
Didi allows users, drivers, and staff to "make a big noise" and figure out the problem in complaining, ridiculing, and speculating. This is a good thing.After all, it opened the door to facing the problem directly, but the problem was that the on-site answers were more hesitant, which closed the door to solving the problem again.

Therefore, many netizens have questioned,Is this spending money to scold, or whitewashing and boasting?

Looking at the scope of the problems discussed in this Roast, it is generally limited to shallow levels such as long queuing time, opaque price, inaccurate positioning, inaccurate navigation, and stingy taxi coupons.Safety is rarely discussed.Finally, Liu Qing’s sentence "On security issues, we are not joking" ended hastily. Judging from the effect of solving the problem, this kind of open dialogue seems to "address only the symptoms but not the root cause of the issue". On the surface, it is lively. If you think about it carefully, there is no real solution to the fundamental problem.

For travel, it’s not about how fast you run, but how stable you run without "rolling over". Users don’t necessarily demand how perfect the app is.What matters more is that the service is cost-effective and safe.A correct understanding of the problem is the prerequisite for correcting the problem later.

Some people think that it is difficult to travel, and it is inherently difficult, and they are too harsh on Didi. Many people commute to get off work and travel without Didi. We are patient with service improvement and innovation. As a "breaker", we must have a great responsibility.

Self-blackening is a good starting point, don’t keep "blackening".Liu Qing also realized that "users always think that Didi is cheating people". We have seen too many examples of companies "humbly admitting their mistakes and not changing their lives", such as telecommunications harassment, bidding rankings, big data push… After many companies fall into a crisis, they either pass the problem on to temporary workers to take the blame, or directly attack the media to spread rumors, or hide and be an "ostrich". Didi has chosen a good way to dare to scold, and now it needs more pragmatic actions, otherwise scolding is equivalent to scolding in vain.

Recently, major brands of new car-making forces collectively released the delivery volume in December 2023 and the annual delivery volume in 2023. There is no accident in the dispute of "selling the crown". LI’s sales in December exceeded 50,000 units, and the annual sales reached an astonishing 376,000 units, which is truly "far ahead"; The second place is Weilai Automobile, with the annual delivery exceeding 160,000 units, up 30% year-on-year. The figures are gratifying, but whether its prospects are bright or not is quite controversial. Followed by the car with zero running and Xpeng Motors, the gap between them is very small in 2023, with sales of more than 140,000 units, with zero running slightly ahead. Some "left behind" are Nezha Automobile. In 2023, the delivery volume of Nezha was 127,400 units, down 16% year-on-year.

Obviously, the "Wei Xiaoli" who started almost at the same time have opened the gap in 2023. The good ones can directly challenge BBA, and the poor ones will face the test of survival. In the extremely involuted market, where will the new forces of making cars go?

LI, which has no pure electric products, is "far ahead" in delivery.

Transcript of 2023: In December, LI delivered 50,353 new cars, up 22.72% from the previous month and 137.15% from the same period of last year, which was the first time that it delivered more than 50,000 new cars per month. By the end of December, LI delivered a total of 376,030 vehicles in 2023, up by 182.21% year-on-year. In this regard, LI CEO Li Xiang said, "All the goals in 2023 have been achieved: 376,000, 50,000, 20,000 and 300. Challenge higher goals in 2024: 800,000, 100,000, 30,000 and 2000 ". In other words, the annual delivery target of LI in 2024 is 800,000 vehicles.

In addition, it is worth mentioning that the Ideal MEGA will be officially released on March 1, 2024, which is the fourth model of LI and the first MPV model. The ideal MEGA has made its debut at the 2023 Guangzhou Auto Show and started blind ordering. The estimated price will be less than 600,000 yuan.

Comments: 376,000 units! This means that the delivery volume of LI in 2023 is more than twice that of Weilai, which has completely opened the distance with other new car-making forces "small partners". What’s more commendable is that the price of ideal models is more than 300,000 yuan. On the basis of such a high price, LI can achieve sales of nearly 380,000 units, which is comparable to Mercedes-Benz, BMW and Audi. I have to say that although LI only focuses on extended range and has no pure electric products yet, its ability to find the market and demand is too strong, and "sofa color TV refrigerator" can be a classic case of automobile sales in China!

Facing the "involution", where is Weilai’s future?

Transcript of 2023: In December, Weilai Automobile delivered 18,012 vehicles, up 12.86% from the previous month and 13.89% from the previous month; In 2023, a total of 160,038 vehicles were delivered, a year-on-year increase of 30.66%. On NIO Day 2023, Weilai’s first luxury car ET9 was unveiled, with a pre-sale price of 800,000 yuan, but the new car will not be delivered until the first quarter of 2025.

Comments: In 2023, the delivery volume exceeded 160,000 units, ranking second in the "Five Xiaoqiang", a new force in car manufacturing. Weilai’s report card looks ok, but it is not optimistic in reality. First of all, the sales volume of Weilai’s 160,000 units has an exponential gap from the ideal sales volume of 376,000 units, which is hard to match. On the contrary, there is a zero run and Tucki’s breathing behind it; Secondly, Weilai’s eight models, including ES8, ES6, ES7, EC6, EC7, ET7, ET5 and ET5T, have achieved such an achievement. Correspondingly, there are only three ideal models for sale: L7, L8 and L9. Taking November 2023 as an example, the top-selling models of Weilai are ES6, ET5T and EC6, and the monthly sales of other models are less than 2,000. The industry believes that the out-of-control pace of product iterative update is the main reason why its sales volume is less than market expectations.

The most fundamental reason is that the new energy vehicle market is extremely involuted this year. The high-end smart driving and air suspension that originally appeared only in high-end models have also become popular in models with a price of more than 200,000 yuan. Correspondingly, the Weilai model with a price of more than 300,000 yuan is not so powerful in terms of cost performance. In addition, throughout 2024, Weilai Automobile will not have a new generation of models, so the test it faces will be very great.

Zero running kills a "blood road" in terms of cost performance.

Transcript of 2023: In December, 18,618 zero-running cars were delivered, a slight increase of 0.59% from the previous month and a year-on-year increase of 119.22%. On December 24th, 2023, Zhu Jiangming, the founder of Zero Run Automobile, said in an open letter of the 8th anniversary of the establishment of Zero Run that more than 20,000 vehicles may be delivered in December, but from the latest delivery data, the zero run automobile failed to achieve this expectation. In 2023, a total of 144,155 zero-running cars were delivered, a year-on-year increase of 29.67%.

Comments: In 2023, the zero-run car wanted to understand a truth, that is, it did not have outstanding brand recognition. If it wants to survive and develop in this cruel market, it can only be "rolled up", and the main thing is a high cost performance. In the first half of 2023, it carried out one-step price reduction. For example, as a medium and large-sized new energy car, the zero-run C01 started at 145,800 yuan for the extended-range version and 149,800 yuan for the pure-electric version, and its cost performance was "bursting". After the zero-run T03 discount, it is only 49,900 yuan, which is also quite prominent in the small pure tram camp!

After getting rid of the crisis, Tucki finally got better.

Transcript of 2023: In December, Xpeng Motors delivered 20,115 vehicles, up by 0.37% month-on-month and 78.13% year-on-year, and delivered more than 20,000 vehicles for three consecutive months, reaching a new monthly delivery record. In 2023, Xpeng Motors delivered 141,601 vehicles, up by 17.26% year-on-year. In addition, it is worth mentioning that Tucki X9 has just been listed, with the price ranging from 359,800 yuan to 419,800 yuan. As the flagship model under Tucki’s "Boom" structure, the new car is positioned as a medium and large MPV, and its power is pure electric power system.

Comments: Due to the "mistake" in the pricing of G9 at the beginning of listing, Xpeng Motors suffered a decline in sales at the beginning of 2023. Fortunately, Tucki G6 of "last stand" finally showed its sincerity in price, and the starting price of 209,900 yuan really shocked the market at that time, and Tucki’s monthly sales began to sprint towards 20,000 units. Then the new G9 went on the market in September, 2023, with a crazy drop of 46,000 yuan, which once again opened the market. Coupled with the competitive price of X9, Xpeng Motors finally ate a "reassurance"!

Nezha cars are pinned on overseas markets?

Transcript of 2023: Nezha Automobile delivered 127,496 vehicles in 2023, down 16.16% year-on-year. In December, the delivery volume of Nezha automobiles was 5,135, down 58.93% from the previous month and 34.12% from the same period of last year, which was the sixth consecutive month that it ranked last in the list of "Five Xiaoqiang".

Comments: Compared with Ideal, Weilai, Tucki and Zero Run, the presence of Nezha cars in the car world is indeed a little lower, and its current situation is not ideal. In this regard, Zhang Yong, CEO of Nezha Automobile, also conducted a review. He believes that "it was not done well in 2023, mainly because the new and old products were not well connected and the rhythm was chaotic; The listing price of new products is too high, although the adjustment was in place in the second half of the year, it lost the opportunity; Loss-making product lines greatly reduce production; The mode of communication is old and there are good things that can’t be said; The marketing headquarters is centralized and weak in management. " Zhang Yong said that in 2024, Nezha Automobile will launch two new models and adjust its marketing system. In addition, Nezha Auto is seeking to boost its sales through the development of overseas markets. According to official data, in 2023, the sales volume of Nezha Auto in overseas markets exceeded 20,000.

General comment: swim against the current, if you don’t advance, you will retreat

Judging from the situation in 2023, the new car-making forces "Five Xiaoqiang" Ideal, Weilai, Tucki, Zero Run and Nezha are facing different situations. The ideal sales lead is relatively large, and the profitability is also good. Weilai, Tucki and Zero Run are still fighting together in terms of delivery volume. Who can be a big attraction in early 2024? And Nezha Auto needs to make real efforts to improve its sales and presence. At the same time, the competition in the whole new energy market is very fierce. Traditional independent brands, joint venture brands and luxury car brands will all make big moves in 2024, and the situation faced by the new forces of building cars is still grim. As the saying goes, "sailing against the current, if you don’t advance, you will retreat", and "Five Xiaoqiangs" need to have a full sense of competition to further enhance their shortcomings.

　　Intermediaries are an important part of the real estate market. Due to the changes in the real estate market in recent years, incidents of intermediaries "asking for salaries" from developers have also occurred from time to time.

　　Recently, a document titled "Notice on Matters Related to Shenzhen Zhongyuan Feedback Commission Advance" circulated on the Internet, in which the information that "each developer/agent has not paid Shenzhen Zhongyuan’s commission exceeds 1 billion" attracted attention.

　　Well-known intermediaries post for commissions

　　The signature of the online document is "Shi Junrong, CEO of Zhongyuan Group", and the time is August 11, 2023.

　　According to the document, in recent years, the real estate industry has been sluggish, and developers’ capital chains have been broken and thunderous, unable to pay the sales commissions of Zhongyuan Group and its related companies normally, resulting in consecutive huge losses and difficult operations.

　　According to First Finance, insiders of Zhongyuan Group confirmed the authenticity of the above documents to First Finance.

　　"According to the practice of the real estate sales industry for many years, the income of sales personnel includes basic salary and commission, and the commission needs to be paid after receiving the sales commission from the developer/agent." The above-mentioned commission payment system has been implemented by Zhongyuan Group since its establishment 45 years ago, and the basic salary part of employees has always been paid in full on time every month, and there has never been any delay in salary or malicious arrears of salary.

　　Regarding the commissions not received by employees, the above-mentioned document states that if Shenzhen Zhongyuan is required to advance the commission without receiving the sales commission from the developer/agent, even if only the commission of the grassroots employees is advanced, the amount of funds that need to be advanced has exceeded 400 million yuan, which will make the company’s operation more difficult. For the reasons mentioned above, Zhongyuan Group and Shenzhen Zhongyuan do not have the prerequisites for advance payment of employee commissions and partner commissions without receiving the sales commission from the developer/agent. However, considering the living difficulties of some particularly difficult employees, the board of directors of Zhongyuan Group has decided to issue special hardship pensions to employees with special difficulties. Employees with special needs can submit applications according to the process, and the group employee association will review and approve them.

　　Involving Evergrande, Baoneng, etc

　　According to public information, Shenzhen Zhongyuan belongs to Zhongyuan Group, which was established in 1978 and is a large-scale comprehensive real estate service enterprise mainly engaged in real estate agency business, including property management, measurement and valuation, mortgage agency, asset management, data integration, and investment immigration.

　　The company’s official website shows that currently, Zhongyuan Group has more than 55,000 employees, 2,500 directly-operated floor shops, and has established branches in 60 cities around the world, with business reaching hundreds of cities. It has become a pioneer and leader in the real estate agency industry.

　　According to the Shanghai Securities News, Shenzhen Zhongyuan is the abbreviation of Zhongyuan Real Estate Agency (Shenzhen) Co., Ltd. It is a large professional real estate agency company in Shenzhen. Since 2001, the number and sales volume of real estate agents in the secondary market have accounted for the main share of the Shenzhen real estate market.

　　Shenzhen Zhongyuan provides research services for government land investment, full consultation planning and sales agency services for developers, and residential, office, shop, factory rental and sales brokerage services, as well as mortgage, appraisal and other services for customers in Shenzhen and Hong Kong.

　　The above-mentioned document states that in recent years, the real estate industry has been sluggish, and the capital chains of major developers have been broken one after another. They have been unable to pay the sales commissions of Zhongyuan Group and its related companies normally, resulting in consecutive huge losses and difficult operations.According to statistics, the developers/agents have not paid Shenzhen Zhongyuan commission more than 1 billionThe court has initiated a lawsuit to pursue the amount of 535 million yuan.Where the court has ruled that the amount of enforcement exceeded 400 millionThe amount to be judged 135 million multiple.

　　At present, the main developers and projects sued by Shenzhen Zhongyuan include Kaisa, Hengda, Baoneng, Shimao, Longguang, and Jixiangli. The above-mentioned real estate developers who have been sued recently are also subject to various news.

　　According to First Finance, Bai Wenxi, vice chairperson of China Enterprise Capital Alliance and chief economist of IPG China, told First Finance that from the perspective of creditor repayment order, the payment of intermediary sales commission should be classified as ordinary creditor’s rights, and the general supplier is in the same sequence, and the repayment order is after the senior debt rights with secured mortgage and other credit enhancement conditions, and before preference share.

　　Bai Wenxi said that in the process of chasing commissions, real estate intermediaries can seize as many of the other party’s effective assets and key current accounts as possible by means of pre-litigation preservation, and then fully negotiate with the other party to achieve maximum reconciliation as much as possible, so as to recover claims as soon as possible.

　　Shenzhen second-hand housingDeal size shrinks

　　A massive loss of employees

　　Data from the Shenzhen Real Estate Intermediaries Association shows that since 2020, the transaction volume of second-hand houses in Shenzhen has continued to decline. From 2020 to 2022, the number of second-hand houses signed online in Shenzhen (the number of sales and purchase contracts initiated on the Shenzhen real estate information platform, and the number of non-final transactions) was 120,295, 44,375, and 26,853, respectively. The number of second-hand houses recorded in the first half of this year was 20,852, only a fraction of the peak in 2020.

　　On July 12 this year, data disclosed by the Shenzhen Real Estate Intermediaries Association revealed that the average monthly turnover of second-hand real estate agents in Shenzhen in the first half of this year was 0.09 units per person, translating to an intermediary who could only sell 1.08 units a year.

　　In recent years, the scale of second-hand housing transactions in Shenzhen has shrunk, leading to a large loss of employees.

　　"At the peak of the market, there were more than 60,000 star-rated intermediaries (real-name registration practitioners) in Shenzhen, but now there are only more than 20,000 people left, and the industry is struggling to survive," said a relevant person from the Shenzhen Fangfang Association. In addition, the "newcomer rate" of Shenzhen’s intermediary industry in the first half of this year was about 21.6%. In 2020, when the market is hot, 49.3% of practitioners are newcomers.

　　The Shenzhen Real Estate Intermediaries Association pointed out that the first-quarter "phased Xiaoyangchun" market in Shenzhen’s second-hand housing market came to an abrupt end after entering April. Even from the second quarter, the monthly transaction volume continued to drop, and returned to the embarrassing situation of less than 3,000 units per month during the annual epidemic. In the final analysis, after the market bottomed out, market confidence has not been completely restored. After entering the second half of the year, with the accumulation of new housing sales pressure, the white-hot competition for second-hand housing and the weakening of market expectations for policies, in the absence of any support to stabilize expectations, it may be difficult for the market to reproduce a similar "phased Xiaoyangchun" market in the first quarter in the near future.

　　The daily economic news is comprehensive from Securities Times, China Business News, Shanghai Securities News, etc

　　Recently, on the 24th anniversary of Macau’s return to China, Autonavi Maps announced the official launch of "Guangdong-Hong Kong-Macao Integrated Navigation". This service is based on the research and development of the Beidou satellite navigation system, and is committed to providing accurate and convenient navigation and travel services in the Greater Bay Area. It realizes a seamless connection with the use experience of Autonavi maps in the mainland, so as to better serve the increasingly hot "south-up-north-down" two-way travel and promote economic integration and development. This is also the first map navigation product in the industry to span the Guangdong-Hong Kong-Macao region and achieve a unified experience.

　　According to reports, in order to achieve the goal of integrated travel and navigation in the Greater Bay Area, this Autonavi map is based on Beidou positioning technology and has launched a number of innovative functions for Hong Kong and Macao, including lane-level navigation, intelligent traffic light countdown, tunnel navigation, and intersection guidance maps, etc., which have greatly improved the level of route planning and navigation services in the Guangdong-Hong Kong-Macao Greater Bay Area.

　　For example, the Beidou lane-level navigation service, Autonavi’s self-developed deep learning model, can realize the 3D automatic modeling of the whole road network integration, and realize the fully automated 3D mapping of building roads, natural environment, urban landmarks and other elements in the map in Hong Kong and Macao; and based on the AI dynamic vision technology for driver human factors engineering, it can dynamically adjust the navigation screen closer to the driving perspective according to the current location and road shape, and build a digital world that combines virtual and real, allowing users to see what they get during the navigation process, "second understanding".

　　After the launch of "Guangdong-Hong Kong-Macao Integrated Navigation", Autonavi Beidou lane-level navigation has been further popularized nationwide and has become the largest lane-level navigation service in the world.

　　There is also an intelligent traffic light countdown service, which is also based on the continuous and stable positioning ability of the Beidou system, combined with cutting-edge technologies such as artificial intelligence and smart transportation to build core computing power, so that the real-world traffic light countdown countdown can be realized on the APP. "Mirror" reproduction.

　　According to reports, the Autonavi smart traffic light service was first launched in the mainland in May 2022. This is the first red light countdown service in the industry to be launched on the smartphone terminal and "anticipate" second-level changes in computing power. As of now, the daily countdown service provided by Autonavi smart traffic lights nationwide has exceeded 2 billion.

　　In addition, Autonavi tunnel navigation has also been launched in Hong Kong and Macao. Based on the self-developed "inertial navigation spatial positioning technology", it integrates mobile phone sensors, road networks, mobile networks, satellites and other elements for mixed real-time computing, which greatly alleviates the stability of positioning signals in tunnels.

　　Autonavi tunnel navigation was first launched in March this year and is the first domestic tunnel navigation technology solution with complete positioning capabilities and based on smartphones.

　　There is also the Autonavi cross-city bus service, which can also realize the integrated travel plan planning that spans any city and region in the Greater Bay Area, covers multiple travel modes such as bus, walking, cycling, and calculates extremely fine time and distance, truly achieving a "door-to-door without dead ends", one-click intercity public travel planning service.

　　In addition to the above features, Autonavi Maps has also added practical services such as intersection guidance large map, riding and walking navigation in the Greater Bay Area, and greatly updated and optimized the data "freshness" in the area (for example, the Hong Kong-Zhuhai-Macao Bridge that has just started trial operation has also been included in the route planning plan), dedicated to further strengthening the unity of navigation and travel services in the Greater Bay Area.

　　As a professional provider of digital map content, navigation and location-based service solutions, Autonavi Maps has always been committed to using technological innovation to transform various cutting-edge technologies into civilian transportation services to provide users with a better travel experience. In the future, Autonavi Maps will also continue to improve in the field of technology to better serve the transportation of the majority of users.

On December 6th, Autonavi Maps launched a new truck navigation function, which is a new feature introduced by Autonavi Maps for special needs groups after the launch of barrier-free maps. Truck navigation can help many drivers accurately avoid the restricted and restricted routes of trucks, making it smarter and safer to travel in large cars.

With the rapid development of logistics freight and e-commerce, truck drivers have now become a very large social group. According to statistics, there are currently about 30 million truck drivers in China, and there are 15 million road freight vehicles, with an average of more than 84 million tons of goods in transit every day.

Due to the strong demand for long-distance, long-distance and multi-frequency travel, truck drivers rely heavily on mobile maps and navigation applications. Autonavi traffic big data shows that trucks in some areas use navigation for an average of more than 400 minutes in a month. At present, there is no accurate and easy-to-use product in the mainstream map applications in China that can fully meet the requirements of truck drivers.

"Trucks should have the highest requirements for navigation and map data fineness among all vehicle types." The relevant person in charge of Autonavi Maps said that due to the strict height, width, weight, and travel restrictions on the road, once the truck enters the restricted road section, it is more difficult for the truck to turn around, not only to pay fines for violations, but also to cause road congestion and even cause safety risks.

There have been many similar cases this year. In late November this year, under the overpass of Jianshe Road, West Third Ring Road, Zhengzhou City, a refrigerated truck was stuck under the overpass while passing a bridge with a height limit of 3 meters. Traffic data showed that after the accident, the congestion delay index of the relevant road section (the travel time of traffic congestion passing/the travel time of free flow passing, the higher the index, the more serious the congestion) peaked at 4.11, and the congestion delay index was greater than 1.8 for about 8 hours throughout the day.

Autonavi map truck navigation is to solve the urgent needs of 30 million truck drivers. When drivers use it for the first time, they can directly use this function by adding basic parameters such as truck type, brand, weight, length and width. During the use of truck navigation, Autonavi map performs intelligent calculation based on high-precision big data, and will automatically plan a navigation route that meets the restrictions of all aspects of the truck they drive. The road is safe and smooth to avoid violations and dangers.

It is understood that the current Autonavi map has covered more than one million truck weight limits, height limits, width limits, axle load limits, travel restrictions, bans and other road information across the country. In addition, the Autonavi map also specially adds the location data of truck checkpoints across the country, and provides navigation and voice reminders during the navigation process, allowing drivers to know the number and location of checkpoints.

Another new feature of the Autonavi map, "Team", is also very suitable for the needs of truck drivers. The so-called "team" means that drivers share each other’s real-time location through the same group of team passwords, and can be displayed in real time on each other’s Autonavi map navigation interface, which is convenient for each other to view and find. Since truck drivers often start in teams when delivering goods, and the journey is long, they can take care of each other through the "team" function of the Autonavi map. In addition, with the help of this function, cargo owners and card sisters can also check the real-time location of drivers and keep abreast of their movements.

"Truck navigation once again reflects Autonavi Maps’ professional and profound accumulation in big data." The person in charge said that Autonavi Maps has Class A surveying and mapping qualifications for navigation electronic maps, Class A qualifications for surveying and mapping aerial photography, and Class A surveying and mapping qualifications for Internet map services. As of the first half of 2017, Autonavi traffic big data has covered 360 + cities across the country, as well as 7.90 million kilometers of navigation road data, with more than 400 kinds of road attribute information alone.

The launch of truck navigation has once again enriched the travel services of the Autonavi map easy platform. The easy platform is the one-stop public travel service platform first launched by Autonavi in the middle of this year. It has previously been connected to many travel service providers such as Didi Chuxing, Shenzhou Special Car, Shouqi Car, Mobike, ofo, and Flying Pig.

　　Haze has made people aware of the existence of PM2.5, serious diseases have made people aware of the harm of formaldehyde, and air purification products have gradually gained recognition from the majority of users. But users who have in-depth understanding know that although air purifiers have obvious effects, they actually treat the symptoms rather than the root cause. The ultimate solution for indoor air purification is a fresh fan.

　　Xiaomi, which used to revolutionize the air purifier market with its signature price/performance ratio, is here again with a new fan. The average price of high-performance new fans over 10,000 is the threshold for its low awareness and popularity. Now Xiaomi is ready to break the industry’s profits again.

　　On November 6, the official Weibo of Mijia officially released the Mijia fresh fan. The price of 2XXX was reasonable and unexpected. As for whether this product really provided extremely high performance at a very low price, the Global Network Technology Channel was invited to experience it in advance to bring you a first-hand experience.

　　A fresh fan is to an air purifier what an air conditioner is to a refrigerator

　　Does indoor air purification require only an air purifier? Of course not.

　　Air purifiers can purify indoor air quickly and efficiently, which is an indisputable fact, but the source of indoor air is still outdoor. If the outdoor air is out of the meter, you can’t open the window, and if you don’t open the window, you can’t ventilate. Even if there is an indoor air purifier, it just keeps self-circulating, and the concentration of carbon dioxide will get higher and higher. Finally, you have to open the window to introduce the outdoor air containing oxygen, and then use the air purifier to purify it.

　　But opening the window once, polluting the indoor air once, and then purifying it again and again, this operation will repeatedly harm health. And directly opening the window and using an air purifier is exaggerated to say that it is equivalent to purifying the entire atmosphere (impossible to do), just like opening the refrigerator door and trying to use the refrigerator to cool the entire room. The self-circulation of the air purifier will naturally make the indoor air cleaner and cleaner, but the air quality is not only an indicator of PM 2.5. At present, carbon dioxide has been included in the current indoor air Quality Standards at home and abroad, and there is a broader consensus that talking about air quality without carbon dioxide is a hooligan. Air that lacks oxygen, no matter how clean it ****** also dangerous to life. This is the importance of fresh fans.

　　From the perspective of the Mijia new fan, the lower part of the trend has a punch or so, which directly introduces the outdoor air, and then filters through the lower, middle and upper layers to send the trend air from the top, which solves the problem of oxygen-containing air source.

　　What kind of fresh fan is Mijia fresh fan?

　　When people hear "fresh air", they are often linked to "fresh air system", which actually refers to the central fresh air system. Generally, air is sent into each room through pipes, which needs to be installed before decoration (hard installation). Most of them are ceiling type, which is more popular in Europe and the United States. However, the central fresh air system occupies a floor height, and it is inconvenient to replace the filter screen. The total cost of final purchase and installation is generally more than 30,000 yuan.

　　As people pay more attention to air quality, the demand for fresh fans after installation has increased, and wall-mounted fresh fans have appeared on the market, which is the category that Mijia fresh fans belong to. The cost of wall-mounted fresh fans is generally around 10,000 yuan, and they can be installed at any time without laying pipes. The installation of Mijia fresh fans only takes two hours, and the bottom air inlet hole is still reserved on the side. Users with insufficient wall space in their homes can install them horizontally. If the property does not allow openings, glass openings can also be selected. Therefore, Mijia fresh fans are very competitive in terms of economic cost and energy cost.

　　The Mijia fresh fan adopts a touch-sensitive OLED display screen, which can be operated directly after displaying the value. The design of the whole machine follows the simple style of Mijia, and it does not violate the integration into the home design.

　　In terms of working principle, the Mijia fresh air fan uses a DC inverter fan to intake air from the bottom air inlet hole, and passes through the lower anti-mosquito filter, the middle-layer medium-efficiency filter, and the upper-layer H13 high-efficiency filter, for a total of three layers of filtration. The anti-mosquito filter adopts a box design to block large particles such as outdoor mosquitoes; the medium-efficiency filter has a removal rate of 80% for particles above PM 0.4; the H13 high-efficiency filter has a power efficiency of more than 99.97% for particles above PM 0.3, and the sterilization rate of Staphylococcus albicans is > 99.9%.

　　What’s more eye-catching in terms of parameters is that the Mijia fresh fan has a ventilation capacity of 300m3/h, which is the high performance of about 10,000 yuan of products on the market. It can ventilate a family with a usage area of 105 square meters 1.1 times an hour. However, the quality of the product still needs to be determined by the actual experience.

　　Actual use effect

　　In order to verify the purification effect of the Mijia fresh fan, we conducted a simulation test: using dry ice to increase the indoor carbon dioxide concentration, using toilet water to simulate indoor formaldehyde and other tVOC pollutants, and closed the window and closed the door in the bedroom (about 30 square meters) where the Mijia fresh fan was installed. When there is severe hypoxia and the aroma is tangy, the data of the Qingping air detector shows that the instantaneous carbon dioxide concentration in the house reaches 4713 ppm, and the tVOV concentration reaches 4.46mg/m3. Far beyond the reasonable indoor range: carbon dioxide below 1000ppm and tVOC should be between 0.2 and 2mg/m.

　　Half an hour later, when we entered the bedroom again, there was already a slight chill, the air was as cold as if the window was open, the smell of perfume was impossible, and the air was very fresh. At this time, the reading of Qingping’s air detector showed that the concentration of carbon dioxide was 508 ppm, and the concentration of tVOC dropped to 0.859 mg/m3. In fact, when the test was carried out for 15 minutes, the concentration of tVOC had reached a reasonable range of close to 1 mg/m3.

　　After the actual test, the ventilation effect of the Mijia fresh fan is indeed obvious, and if installed in one room, it can actually ventilate the whole family, just like opening the balcony window.

　　The most impressive thing is that when you stand in front of the machine with the window closed, you can only hear the noise of the outdoor road, and you can’t feel the operation of the machine at all. It is understood that the Mijia fresh fan is only 35.4 decibels under the maximum air volume, and the sleep mode is as low as 20.4 decibels, which is basically half of the general noise of commercial products.

　　At this point in our experience, we almost forgot about PM 2.5. The original value has been reduced from 6.3 to 2.2. It seems that as long as it is turned on, the indoor air quality has no need to worry at all. But some users may wonder, Mijia fresh fan does not have activated carbon filter element, how to remove formaldehyde?

　　In fact, the air purifier uses activated carbon to absorb formaldehyde only for collection and storage, and there is a risk of secondary volatilization when the indoor temperature is high. The fresh fan uses a continuous ventilation method to let formaldehyde squeeze out of the door and window seams with the "micro-positive pressure" formed by the fresh air entering the house.

　　It is worth noting that formaldehyde does not only exist in houses that have just been renovated. Over time, cracking of wooden furniture joints and tilting of the skin will cause the originally sealed formaldehyde to continue to evaporate, so continuous ventilation is the way to treat the symptoms and root causes.

　　When Mijia products are as ubiquitous as air

　　Users who have paid a little attention can feel that Mijia’s products have become more and more abundant. Nowadays, air purification products have also extended from air purifiers to fresh fans. As long as they are users who can shop online, they all have one or two Xiaomi ecological chain products. They are really as ubiquitous as air.

　　While Mijia products bring benefits, what’s more important is to string together smart life. Mijia new fan also supports Xiao Ai voice control, which can synergy with other Mijia smart home products. Of course, there are also mobile phone remote control switches, air volume adjustment, electric auxiliary heat adjustment, check the status of consumables, etc.

　　Obviously, no matter how consumption is upgraded or downgraded, our spending on health cannot be saved, and air is the most important element for survival. Therefore, we also hope that with the promotion of Xiaomi, more users will understand the necessity of buying new fans and make the right choice for the health of their families.

　　Reference News NetworkReported on August 22Russian media said that the creation of a Sino-Russian joint orbital cluster (consisting of 50-55 satellites) will help use the Beidou Satellite Navigation System (BDS) anywhere in the world. Many Asian countries are now using the Beidou Satellite Navigation System. Andrei Jonin, a member of the Russian Government Expert Council and a corresponding member of the Russian Academy of Sciences, was interviewed by the Satellite Communications Agency and made the above statement on the completion of the compatibility test between the Russian GLONASS satellite navigation system and the Chinese Beidou satellite navigation system.

　　According to the Russian Satellite Network on August 19, Jonin said that after building a unified satellite cluster, "concerns about possible movements of Americans and Europeans will be completely eliminated." He pointed out that Americans can cut off the global satellite positioning system and do whatever they want with it, but this has no impact on consumers of GLONASS and Beidou services.

　　According to the report, the study of navigation conditions along the Silk Road Economic Belt by Chinese and Russian experts ended simultaneously. In Russia, the test route was carried out in the promising "Europe-Western China" international transportation corridor, with a total round-trip distance of about 7,000 kilometers. Chinese experts carried out tests along the route of Xi’an-Lanzhou-Urumqi-Khorgos, with a total length of more than 3,200 kilometers.

　　According to the report, the two sides analyzed the operating conditions of the navigation system, the possible interference of using two navigation systems simultaneously, the coverage of traffic lines, and other parameters required for high-precision navigation. The resulting data will help the Chinese and Russian researchers to draw conclusions about how much more accurate the two systems, Glonass and Beidou, can be when operating together than when operating separately.

　　Yonin has no doubt that Beidou will become a global satellite navigation system for Chinese military personnel by 2020.

　　According to the report, China has set this mission, and Jonin said that there is no doubt that China will solve this task. China plans to launch satellites because their current orbital cluster lacks some satellite composition for global coverage. China will have 30 satellites in orbit by 2020, which is enough to solve its own military mission at any time and any place. But the global Beidou will only be used for military purposes, and 30 satellites will not be enough for civilian purposes, because with most consumers living in cities, 50 to 55 satellites are required. That is to say, the Sino-Russian joint satellite cluster is sufficient for them. In this scenario, Beidou becomes a global satellite navigation system, like GPS and Glonass. You can call this orbital cluster whatever you want – the China-Russia orbital cluster, the SCO orbital cluster, the BRICS orbital cluster… The main thing is that it will be independent, so after the construction is completed, all countries that want to use this orbital cluster can no longer worry about any movements of the Americans and Europeans.

　　Experts explain that in the event of a conflict between China, Russia, China, Russia, and the United States, all consumers of GLONASS and Beidou navigation services will not be harmed in any way. This is important for all countries concerned about US sanctions, including those related to the use of GPS.

　　During the test, the possibility of providing high-precision navigation services by the future joint system of Glonass and Beidou was analyzed, that is, the coordinate position was determined within the accuracy of tens of centimeters or even a few centimeters, rather than within the accuracy of 10 meters to 15 meters. Yonin pointed out that, indeed, for current car freight or railway transportation, this problem is not so urgent at present.

　　For the future mode of transportation, it is also called "smart driving" or "partially driverless", and so-called "caravan driving", which means that multiple trucks form a kind of serpentine formation, and the driver of the first car guides the entire caravan. All this is necessary. What is needed here is high-precision navigation. So, it is very good to have started to study this problem for the future.

　　According to the report, Russian experts estimate that, like the entire project, the test results will help ensure high-precision satellite navigation services for Chinese and Russian consumers in the coming decades. The Sino-Russian joint navigation system is a strategic project. It is no accident that the above cooperation direction is regarded by both sides as the most promising direction in the high-tech field.

　　Recently, Netcom obtained the official picture of Tiggo 8 PRO Kunpeng e+ from Chery Automobile. From the official picture, we can see that the appearance and interior design of the vehicle are basically the same as the ordinary version, which is very atmospheric and beautiful, and there is no obvious difference on the whole. Earlier, it was reported that the new car will be listed in May.

　　The front of the new car still uses a large-size air intake grille. The design is consistent with that of the gasoline version, which looks very fashionable. The internal matrix structure also adds a sense of exquisiteness to the appearance of the vehicle. In addition, the headlights of the new car are connected with the front grille, which not only enhances the visual width of the front face, but also brings a strong sense of integrity.

　　A large number of curved surfaces are used on the side of the vehicle, and a wide-body design is formed at the front and rear, which makes the body look very burly and powerful, and the profile of the side is also relatively robust, giving people an atmospheric feeling.

　　In terms of the tail, the shape of the tail is full of layers, and the popular through taillight shape is adopted, which enhances the visual width of the tail and is expected to have a good visual effect after lighting. Below, we can see that the vehicle uses the exhaust gas from both sides, and the sports atmosphere has become more intense. We can also see the four-wheel drive logo at the rear of the vehicle, which proves that the vehicle has a four-wheel drive version.

　　Inside the car, the new car adopts a minimalist and atmospheric design concept. The design of the dual screen is particularly eye-catching, with a size of 24.6 inches. It is also equipped with a W-HUD head-up display function, which can display speed, driving assistance, navigation information, telephone information and other contents. The most important thing is that this configuration is more conducive to safe driving.

When it comes to the domestic automobile market, there are only a handful of independent brands, and BYD is one of them. However, compared with the Great Wall and Geely, BYD has not only succeeded in the field of fuel vehicles, but also shined in the field of new energy, such as the Qin Pro EV (parameter picture) that we are going to analyze today.

There are 8 models of Qin Pro EV on sale, with a guide price of 149,900 to 204,900. However, after subsidies, the price of Qin Pro EV is 144,900 to 199,900. As a compact car, this pricing is actually relatively high, but the cost performance of BYD’s models is generally good. Continue to learn about Qin Pro EV.

Although Qin Pro EV is a pure tram, it is hard to detect in appearance. It basically copied the design of the fuel version and continued BYD’s "Longyan" design concept. The recognition of the front part is also very high. The large-area medium mesh grille adopts lattice structure, which has a strong sense of exquisiteness, and diversion grooves are also designed on both sides of the front enclosure.

The shape of the headlights is also very exquisite, and the top is also connected with a chrome trim strip, which has a feeling of "dragon eyebrow". And Qin Pro EV is equipped with matrix LED headlights, which are bright and murderous after lighting. However, only three models, namely the exclusive model, the leading model and the leading model, are equipped with adaptive far and near light.

The shape of the side of the car body is also very dynamic, and the lines on the roof have a slippery breath, so the overall look is also a bit of a coupe. The design of the waistline is also very aesthetic, extending from the headlights to the top of the taillights and blending with the tail lines. In terms of body size, the length, width and height of Qin Pro EV are 4765/1837/1515mm, and the wheelbase is 2718mm. This parameter is average and below average.

The shape of the wheel hub is also very dynamic. Except for the travel version and the pilot version, which are equipped with 16-inch wheels, tyre size is 225/60, and other models are equipped with 17-inch wheels with multi-spoke and two-color shapes, and tyre size is 225/55.

The shape of the rear part is simpler, the overall layering is richer, and more horizontal lines are used. The design of the through taillight is also very bright, with a chrome trim in the middle, and the left and right sides extend longer, and the recognition after lighting is ok.

Entering the car, Qin Pro EV’s interior design is also very layered, and it also uses more horizontal lines, but if its line curvature is larger, there will be a circular layout in the car. The performance of Qin Pro EV is average, only the top of the center console is covered with soft material, and other places are made of hard material, but its decorative pattern design is still very beautiful.

The steering wheel has three flat-bottomed structures. Except for the leading model, which is wrapped in leather, other models are only wrapped in leather, but the grip is also excellent. The layout of multi-function buttons is also reasonable, and it is not difficult to control, and the logos of all BYD models’ interiors are in Chinese, which is commendable.

The design of the dashboard always looks awkward, although it is very conventional. The whole system adopts an 8-inch full LCD screen, and adopts frameless design. The display effect is very delicate, and the UI interface design is also very intuitive, which can read a lot of information about the vehicle condition.

The design of the central control office adopts BYD’s usual suspension type and supports rotation, but only the Lingshang, Lingyao and Lingchuang models use a 12.8-inch touch LCD screen, while the Lingshang, Lingshang and Lingyue models use a 10.1-inch touch LCD screen. The travel version and the pilot version are only equipped with an 8-inch touch LCD screen, but a 10.1-inch touch LCD screen is optional.

The integration ability of this central control panel is also relatively strong, although it is very routine, such as air conditioning system, entertainment system, active safety system and vehicle settings can be operated in it. The car system it carries is also rich in functionality, supporting navigation, road information display, road rescue, Bluetooth phone, voice recognition control and car networking, but the travel version and the pilot version do not support road rescue and voice recognition control.

In passive safety configuration, only the Lingyao model is equipped with 6 airbags, other models are only equipped with 4 airbags, and only the travel version and the pilot version are equipped with tire pressure alarm, and other models are equipped with tire pressure display. In terms of active safety, only the three models, namely, the exclusive model, the leading model and the leading model, are equipped with lane departure warning, lane keeping assistance, road traffic sign recognition and active braking.

In terms of driving assistance control, the three models of Lingshang, Lingdong and Lingyue are only equipped with rear parking radar, reversing image and constant speed cruise, while the three models of Lingxiang, Lingyao and Lingchuang are equipped with front and rear parking radar, 360-degree panoramic image and full-speed adaptive cruise, while the travel version and the pilot version are only equipped with rear parking radar.

The shape of the seat is also very interesting, with more stitches. The cushion and backrest are also decorated with stripes, and the word "Qin" is embroidered above the backrest. The comfort and wrapping of the seat are also quite satisfactory. There is little difference between the rear seat and the front seat, but the comfort is better and the wrapping is good, but the middle seat is not equipped with headrest.

In the sitting space, adjust the front row to a suitable position. The height of the experiencer is 1.8 meters, and there are four fingers left in the head space. Keep the front seat unchanged, enter the back row, there are more than three fingers left in the head, and there are still three fingers left in the leg space. For this class of cars, this performance is quite good. Except for the travel version and the pilot version, which are not equipped with skylights, all other models are equipped with electric skylights.

Power: All Pro EV systems in Qin adopt the layout of front single motor, but three kinds of power motors are provided. The maximum power and torque of the motors equipped in Lingshang, Travel and Pilot versions are 100kW and 180N·m respectively. However, the maximum power and torque of the motors equipped with the leading type, the enjoying type and the leading type are 120kW and 280N·m, and the maximum power and torque of the motors equipped with the leading type and the leading type are 135kW and 280N·m. The transmission adopts a single-speed fixed gear ratio gearbox, while on the chassis suspension, the travel version and the pilot version adopt the combination of front McPherson independent suspension and rear torsion beam dependent suspension, while other models adopt front McPherson independent suspension and rear multi-link independent suspension.

In terms of endurance, Qin Pro EV also provides three kinds. The leading version, the travel version and the pilot version use a ternary lithium battery with a battery energy of 53.1kWh and a battery life of 401km. The ternary lithium battery equipped with the leading, enjoying and leading models has a battery energy of 56.4kWh and a battery life of 420km, and the battery life of the leading and leading models is 520km. The ternary lithium battery also used has a battery energy of 69.5kWh.

Generally speaking, the competition in the new energy market will only become more and more fierce. The overall strength of Qin Pro EV is good and competitive, but there is still room for improvement, at least it makes people feel sincere. Now it gives me the feeling that it is always a little less interesting, and I may have seen a car with higher cost performance.
