Have you noticed that the QR code scanning boxes of WeChat and Alipay are disappearing？

This article comes from WeChat WeChat official account:Ai faner (id: ifanr), Author: Chen Wenjun, title map from: vision china

We scan the code almost every day, log in to the website, register information, pay for consumption, add friends … As long as we open it and scan it, we can save a lot of tedious steps.

Every time you turn on the tool to scan the code, these tools usually give a 1:1 scanning code box. Align the box with the QR code, and the mobile phone can immediately identify the information in it.

However, I wonder if you have noticed that even if these tools frame the "scanning area", sometimes scanning can be completed without aligning the frame. As long as the QR code is within the camera’s framing range, the system can immediately identify the content.

Then what’s the use of this box?

In fact, this has a lot to do with the purpose of each app scanning function. Looking at the 10 most commonly used apps in our daily life, the design of QR code scanning pages can be divided into several categories:

Fixed-area scanning is the code scanning mode that we are most exposed to at present. Users need to aim their mobile phones at the QR code scanning to make them recognize. If the target QR code is not in the frame, the app cannot recognize the content.

In some of our more commonly used apps, such as WeChat and Alipay, they have changed from "fixed frame scanning" to "full screen scanning", that is, the entire mobile phone screen is a scanning frame.

The mobile phone can recognize without facing the QR code, and the recognition speed is much faster than that of framed scanning. Before the camera is in focus, the system can recognize the information immediately.

The QR code can be recognized even if it is not in the box (the actual speed is faster than GIF).

Of course, there is also an example here. When I turn on Weibo code scanning, the page is designed with a fixed code scanning area, but the scanning mechanism of app is actually full screen scanning. So every time I prepare to scan, the information has been read before the QR code enters the box.

Is the designer lazy? Not necessarily.

It is obviously not enough to pry open the details of the scanned page, but also need to consider from many aspects, such as the hardware used for code scanning and the decoding ability on the software level.

In fact, it is not difficult to make the scanned code page full screen, but it is not unnecessary to vacate a box as the scanning area.

The reason is that when the QR code first entered our life, neither the app itself nor the code scanning equipment was specially optimized, and the success rate of code scanning was often related to the ambient light, distance and clarity of the QR code.

Personally speaking, the code scanning area provides a hint of code scanning recognition, and its task is to tell the user that the camera is ready for scanning, so long as it is aligned, the information can be read. As for the device itself, whether the camera can quickly identify the QR code has something to do with the focusing performance of the camera and the decoding operation ability of the processor.

The history of QR code can be traced back to the 1980s, but it didn’t begin to spread to our daily life until the past decade.

However, in the early days, the focusing response and speed of smart phones were relatively slow, and they were also easily affected by ambient light and lens clarity. Therefore, when developing app scanning pages, developers need to adjust the camera’s framing range to make the camera focus on a specific area, instead of focusing on a wide area.

The code scanning speed of the old mobile phone is slower than that of the new mobile phone (pay attention to the focus bellows and use Meizu MX5 test)

Simply put,Separating the code scanning area is actually to take care of the equipment with relatively slow focusing speed in the early days.. The principle is similar to the fixed-point focusing area of the camera. The camera only measures and focuses on the area within the square frame, thus reducing the interference of other factors around the target QR code, thus improving the camera focusing speed and the success rate of code scanning.

Looking at it from another angle, the code scanning box is not only a way to tell the user that the scanning function is on, but also a way to improve the recognition accuracy. As long as the key elements of the QR code in the box meet the requirements, the recognition accuracy is about 100%.

In order to enable users to scan codes in different environments and conditions, developers will integrate flash, remote automatic zoom, etc. when using scanning code development libraries such as zxing, all of which are aimed at enabling mobile phones to see the QR code information in the box and facilitate users to scan in any use situation.

However, in recent years, the camera focusing speed of smart phones has improved rapidly, and the ability of the core processor to process images has gradually improved. Therefore, modern mobile phone code scanning does not need long-term focusing, even if it does, it can only be completed in less than one second.

At the same time, with the application of QR code becoming mainstream, app developers also improve the speed and success rate of code scanning by creating their own code scanning engine, instead of relying solely on the hardware level to complete the identification process-WeChat is one of them.

Although WeChat is not the first app to use QR code, it has to be admitted that it is the most frequent app to use QR code and scan code, which not only makes users think of WeChat once they mention "scan code", but also indirectly promotes WeChat’s development of scan code technology.

Before QBar came out, there were mainly two kinds of code scanning engines, zxing and zbar. These two engines have different advantages, but both have their own shortcomings. At the same time, these two engines have more restrictions on barcode recognition than QR codes.

In 2016, the WeChat technical team introduced the working principle of QBar code scanning engine in a tweet published by WeChat official account WeChat School.

Compared with the traditional code scanning method, QBar will screen out the barcode/QR code content through the pre-judgment algorithm when scanning the code page, quickly identify the graphic code information in front of the screen through scanning the page, and then decode the image through QBar engine to output the final result.

In other words, when the user opens the code scanning page, as long as there is a barcode or two-dimensional code image in the frame, the system has already started to predict the user’s code scanning target and start to classify and identify it.

GIF can be recognized only in one corner (using WeChat scan function)

And because the QR code itself also has a fault-tolerant mechanism.(Originally designed to make the QR code work normally under damage)In fact, the camera does not need to compare the complete QR code, just find the key points of the QR code within the fault-tolerant range to identify it. Combined with the characteristics of QBar engine, the code scanning camera can identify and decode the QR code and its key information in one second by predicting and screening it.

Flow chart of WeChat code scanning prediction module, picture from: WeChat School

The recognition principle announced by WeChat seems complicated, but in modern smart phones, these tasks can only be completed in a few milliseconds. According to the reference data of "WeChat School",The decoding time of WeChat on iOS client is 5 milliseconds, and that of Android client is 12 milliseconds..

As for why the code scanning speed of iOS devices is faster than that of Android, this may be related to the decoding performance between iOS and Android devices at that time.

IPhone 11 Pro Max uses WeChat code scanning speed (slightly accelerated due to the number of GIF frames).

In the test in the daylight environment, the iPhone using A13 processor has indeed completed the recognition before focusing, and even the iPhone 7 in 2016 can achieve the "one-stroke scanning" response; The Android flagship using Snapdragon 865 also responds very quickly, but there is a slight speed gap compared with iOS.

If the iPhone scan code is "complete identification before you see it clearly", then Android is "complete identification immediately after you see it clearly".

The difference between the two is only in milliseconds.

One plus eight uses the code scanning speed of WeChat (slightly accelerated due to the number of GIF frames)

However, although the scanning speed of Android is slightly lower than that of iOS, compared with the speed difference between the two camps five years ago, the improvement of Android has been very obvious, which is almost the same as the recognition speed of iOS. If you don’t pay attention, you can hardly see the difference between the two.

Therefore, the recognition time of the past 5/12 milliseconds is not absolute, and they will change with the iteration of mobile phone hardware and soft algorithm.

It is worth mentioning that when using Android devices to scan multiple QR codes at the same time, multiple QR codes in the screen will be identified together, and then an entrance will be provided for users to choose their own objects; Although the recognition speed of iOS is faster, when faced with multiple QR codes, the system chooses one more.

Wechat without a fixed scanning frame can identify multiple QR codes at the same time (note: at present, this function is only tested in gray scale in some Android clients)

In addition to WeChat, Alipay also uses a full-screen scan similar to WeChat. Although its recognition speed is slightly slower than WeChat, it can also achieve the level of recognition by raising your hand.

According to the technical documents shared by CSDN users, Alipay’s code scanning function is integrated by libqrencode library. Although it is not Qbar of WeChat, its recognition speed under deep optimization can also be calculated in milliseconds.

With a more perfect algorithm engine and hardware decoding ability, mobile phones have become "sensitive" to the identification of QR codes, and they can quickly identify the contents of the codes without high-definition images.

In this way, the box used to fix the focus in the past will naturally be replaced by full-screen scanning.

Alipay’s recognition speed is also very fast (iPhone 11 Pro Max test).

The changes in the form of code scanning are particularly obvious in the apps with more code scanning behaviors such as WeChat, Alipay and Weibo.

Users can quickly complete code scanning transactions on WeChat and Alipay; Weibo allows users to quickly complete the two-step verification of code scanning.

The change of code scanning speed and accuracy depends on the improvement of code scanning engine and algorithm by several head enterprises, but from the side, it actually benefits from the continuous upgrading of mobile phone hard power. Only a camera with higher resolution and a processor with better computing performance can carry more complex decoding engines and algorithms and realize millisecond scanning code recognition.

IPhone 7 and the old version of WeChat scan box

From the evolution of the code scanning page, it can be seen that the code scanning efficiency of mobile phones is constantly improving, and commonly used apps can complete scanning without aligning codes when scanning codes. Then let’s look back, is the most primitive scanning code box still meaningful?

Actually, there is.

First of all, the current retention rate of old equipment is high, and the service life of smart phones is generally 2 to 3 years, or even 4 to 5 years. The focusing and recognition capabilities of old phones are not as good as those of new phones.

The function of the scanning box, as mentioned above, is convenient for the old mobile phone to quickly find the focus and improve the scanning speed and accuracy of the QR code, and it can also intuitively guide the user to aim the mobile phone at the code scanning, which actually indirectly improves the recognition efficiency of the old mobile phone every time it scans the code.

Although JD.COM and Taobao scan codes are full screen, they still need to be scanned in the frame.

In addition, although WeChat has its own code scanning engine, not all app developers have the ability to develop engines or specially optimize engines.

For the app with little demand for code scanning, the scanning function is mainly to scan the QR code, and the scanning success rate is more important than the speed. Therefore, under the premise of not optimizing the recognition engine, using the original in-frame scanning can ensure that both old and new devices have a high recognition success rate.

The popularity of two-dimensional code greatly simplifies our operation in inquiry, payment and registration, and the mobile phone used to scan it is also becoming efficient and diversified with the upgrading of decoding ability of software and hardware.

Today’s code scanning page can scan more than two-dimensional code, and it can also be combined with neural network to recognize things. According to the introduction of the latest function document of WeChat, based on 850,000 plant image data provided by Kunming Institute of Botany, Chinese Academy of Sciences, at present, the sweeping function can identify more than 36,000 plants, which basically covers the data of flowers and trees we see every day.

It can be seen that the code scanning page is carrying more functions with more meta-algorithms.

For this reason, the scanning code box used to guide users and improve the focusing speed of equipment in the past has gradually withdrawn from the stage with the algorithm upgrade, hardware iteration and the scanning code page supporting more scanning targets. howeverIt didn’t really leave us, just evolved from 1:1 in the past to the same proportion as the mobile phone screen..

Full of fruitful results, go to the new road ＂New Finance, New Business, New Elite＂ Shanghai University of Finance and Economics MBA30 30th anniversary project conference was successfully held!

　　On April 18th, 2021, the launch conference of "New Finance, New Business and New Elite" was held in the International Conference Center of National University Science Park of Shanghai University of Finance and Economics. This conference will be presented online and offline simultaneously. Professor Wei Hang, Executive Vice President of Business School of Shanghai University of Finance and Economics, Director of MBA Center, Professor Chen Zhijun, Academic Director of MBA Center of Business School of Shanghai University of Finance and Economics, and Director of Human Resources Department, and Mr. Xu Lei, Managing Director of Morgan Stanley (China) Equity Investment Management Co., Ltd. attended the conference and delivered keynote speeches, leading teachers, students, alumni and participants of educational institutions to gain insight into new finance, new business subjects and new elites, and to interpret the MBA enrollment policy in 2022 in detail. In addition, the "Shanghai University of Finance and Economics MBA Program 30th Anniversary Promo" was also launched at the press conference.

　　New Finance and Economics, New Business

　　In recent years, the changes in the global finance and financial field have brought far-reaching influence and broad prospects to China’s economy, and at the same time, it has also given birth to business education to actively respond to the new mission of the times. In the keynote speech of "New Finance and New Business", Professor Wei Hang, executive vice president of Shanghai University of Finance and Economics Business School and director of MBA Center, said that at present, Shangcai Business School and Shangcai MBA are focusing on the "new business" based on the future, carrying out brand-new and beneficial exploration and practice.

　　Dean Wei believes that "anti-globalization", "China factor" and "technology-driven" are becoming three prominent features under the background of global "new finance". Under this background, the development of business research and business education will be carried out from three dimensions: new theory, new model and new practice. Under the change of new technical means and scenes, the reform of business teaching mode is imminent. Shangcai Business School is actively exploring related fields. By building a scene-based laboratory, VR, big data and other technologies are used to realize the practice and scene-based business teaching, helping students to learn and practice in the simulation close to the real business environment. At the same time, the college is also building a laboratory and research institute of Mathematical Intelligence College, expecting to better serve the career development and growth of MBA students and contribute more financial strength to the national economic construction and development.

　　The New Elite: Business Ideal, Sailing and Sailing.

　　

　　The current era is an era in which digital intelligence changes the business pattern, and digital intelligence has also become an important standard to measure the competitiveness of the workplace. Professor Chen Zhijun believes that the elites in the workplace need to continue to learn deeply and reshape their values with others as the center to improve their intelligence in all directions.

　　In Shangcai MBA, when the students’ "career pyramid" meets the "academic ivory tower" of business education, Shangcai MBA helps students become explorers of business frontiers, producers of business insights and inheritors of business civilization through a set of "1234" classes (learning knowledge in the first class, doing practice in the second class, expanding network resources in the third class and realizing self-value in the fourth class) and a perfect training system. Professor Chen Zhijun pointed out that every crisis provides us with a rare opportunity for stress testing and investment recovery, and ultimately it is the values that determine how we will respond and deal with ourselves. Finally, he used an old saying, "If you travel far, you will feel inferior if you climb high", and encouraged everyone to dream and sail far and wide through the study of MBA in Shangcai.

　　2022 MBA Admissions Policy Released

　　The last link of the conference was the release of the 2022 enrollment policy brought by Feng Da, the brand director of the MBA Center of Shanghai University of Finance and Economics. Starting with the eight questions that candidates are most concerned about, Mr. Feng introduced in detail the MBA program and enrollment policy in 2022. Among them, the enrollment scale and tuition fees of the project remain unchanged, and the freshman scholarship has maintained the same strength as the admission in 2021 in terms of outstanding talent scholarships, full and half scholarships. In addition, by accurately depicting the portraits of full-time global classes, comprehensive elite classes, financial investment classes and EMBA students, Mr. Feng introduced in detail the inspection requirements of the four classes for applicants, and made a comprehensive interpretation of the "W+D" pre-interview policy. After the announcement of the enrollment policy, Mr. Feng gave detailed answers to the high-frequency and common questions raised by the candidates, and encouraged the candidates to constantly break through themselves through the preparation for the exam and the study trip. I hope that every dream catcher can get a brand-new motivation to climb the career and life peak in the Shangcai MBA.

　　Thirty years of hardships and hardships, thirty years of youth. The MBA of Shanghai University of Finance and Economics has embarked on an elegant road with the characteristics of business education, from the early crow of young eagles to inclusiveness, and then to accumulation. In the future, the MBA of Shanghai University of Finance and Economics will also meet the needs of the times and lead the times, and continue to provide wisdom and strength for the country’s economic development. At the same time, the project also looks forward to working hand in hand with business elites with lofty pursuits, opening the next exciting period in the workplace and life, and adding more possibilities for the realization of self-worth.

　　More exciting highlights of the conference:

Huang Changfu, winner of ＂National May 1 Labor Medal＂： Writing Heroic Songs Underground

　　Xinhuanet Beijing, April 29th (Zhengxian Xiaomei) On the 29th, 430 advanced collectives won the "National May 1st Labor Certificate" and 1,095 advanced individuals won the "National May 1st Labor Medal" at the International Labor Day Conference held by the All-China Federation of Trade Unions in Beijing. Among the winners of the "National May 1st Labor Medal", there is an underground engineering expert from the fiery Beijing Olympic construction site ―― Huang Changfu, deputy chief engineer of China Railway 16th Bureau Group and commander of Beijing Engineering Headquarters, manager and senior engineer of the underground diameter line project department of Beijing Railway Hub from Beijing Station to Beijing West Railway Station. This model of the times who has been struggling for years has silently written a touching heroic song with his own practical actions.


　　Joining the subway construction, he and his family regard the construction site as their home.


　　In the evening, Huang Changfu, who looked tired, just walked out of the underground diameter line tunnel in Chongwenmen, Beijing, when the mobile phone on his waist rang, there came the voice of his son in tears: "Dad, the children have all gone, and you forgot to pick me up again."


　　"Oh, my son, I’m so sorry. Dad will pick you up right away!"


　　Huang Changfu’s wife works in Tongzhou District, Beijing, and his 4-year-old son is in full-time nursery school in Mudanyuan Kindergarten in Haidian District, Beijing. He himself is busy at Chongwenmen construction site all day. This kind of life, dubbed by the workers as "cross-strait and three places", makes it possible for their family of three to meet only on weekends. Once, the child caught a cold and had a fever. The kindergarten teacher let the parents go, which coincided with his wife’s business trip. Huang Changfu was directing the installation of the shield machine at Shuangjing, so he had to let the driver go to see how the child was. The teacher who didn’t know the truth complained: "The couple are too careless about the children."


　　Hearing the child’s blame, Huang Changfu suddenly thought that today is the weekend and it is high time to pick up the child. It’s no wonder that due to the tight construction period, Huang Changfu and others have never had the concept of Sunday. For subway builders, the most difficult question to answer is probably "What day is it today?" There is no cell phone signal in the tunnel, and the child has been on the phone for a long time. Huang Changfu can’t help feeling deeply guilty.


　　"Dad, are we going home to the construction site or Tongzhou?"


　　"Son, dad is busy, let’s go back to the home of the construction site first!"


　　From the day he joined the subway construction, Huang Changfu regarded the construction site as his home. Not only he, but also his wife and children regard the construction site as their home.


　　Huang Changfu, 36, was born in Xinxian County, Henan Province. Xinxian county has many heroes since ancient times. This is the center of the revolutionary base area in Hubei, Henan and Anhui. On this red land, there have been 43 distinguished generals such as Xu Shiyou, Li Desheng and Zheng Weishan. All these have a subtle influence on Huang Changfu’s growth.


　　In 1998, Huang Changfu, who had just obtained a master’s degree from University of Science and Technology Beijing, came to the construction site of Beijing Subway Fuba Line of China Railway 16th Bureau Group. A person in charge said to him, "subway construction is a profession with complex technology, hard environment and high safety risks. You should think it over."


　　Huang Changfu, who is full of ambition and determined to make a career in the field of subway engineering, replied without hesitation: "I have thought about these questions since the day I set foot in the university gate."


　　Since then, there has been a young figure in the subway construction site under Chang ‘an Street.


　　In the early morning, when people walked into the spacious and bright office building in bright sunshine, Huang Changfu and his colleagues walked into the dark and humid tunnel in long rain boots; In the evening, when they were covered in muddy water, they dragged their tired feet down the tunnel face, and people in fashionable clothes had walked comfortably on the bustling Chang ‘an street … Huang Changfu began to understand the true meaning of the word "hardship". Just out of the institutions of higher learning, he inevitably felt a huge psychological gap. He secretly said to himself, "Huang Changfu, Huang Changfu, you must hold on!" " He grades his will and perseverance every day. Climbing the arch and erecting the grille, he fought bravely for the first place. When encountering construction problems, he carefully studied the construction drawings, asked experienced old experts for advice, and seriously thought about solutions. In a few months, he has basically mastered some procedures and methods of subway construction. Looking at the problems solved one by one, the tunnel moved forward one meter at a time, and his heart involuntarily felt a sense of accomplishment.


　　In May 1999, Huang Changfu was appointed as the deputy chief engineer of the project department of Jiangnan Xincun Station of Guangzhou Metro Line 2 of China Railway 16th Bureau Group, mainly responsible for the construction of the underground excavation section of the north and south station halls. The upper part of this stratum is soft soil layer, which needs to be supported in time after excavation, and the lower part is rock layer, which needs blasting operation. He consulted relevant information, carefully studied the characteristics of rock strata and the foundation of buildings, and put forward the micro-vibration controlled blasting technology, which solved the technical problem of the influence of underground excavation in soft and hard mixed strata and blasting on the foundation of surrounding buildings. Subsequently, Huang Changfu was transferred to Xiaojiang section to be responsible for tunnel construction. This section is the turn-back line of Guangzhou Metro Line 2 and Line 5, including 21 sections and 41 section change points, and almost all the construction methods in the underground excavation method are involved. The biggest difficulty of the project is that it passes through 11 high-rise buildings and needs pile foundation underpinning. Huang Changfu consulted a large number of materials and collected first-hand data in detail. By using engineering analysis and numerical simulation calculation, he analyzed the influence of tunnel excavation on the ground and buildings, determined the number and scope of pile foundation underpinning, solved the pile-beam connection, graded loading and synchronous jacking technology of pile foundation underpinning, and put forward the concept of "load dispersion method", which avoided pile interception and accelerated the construction progress.


　　With the spirit of dedication, striving for perfection and work style, Huang Changfu has grown into an excellent subway construction technology leader and project management backbone in just a few years. Since October, 2002, Huang Changfu has been successively appointed as the deputy manager and chief engineer of the shield engineering project department of Shenzhen Metro Phase I of China Railway Sixteen Group, the project manager and secretary of the Party Working Committee of Beijing Metro Line 10, and the project manager of underground diameter line from Beijing Railway Station to Beijing West Railway Station. Every project managed by Huang Changfu is almost the highlight of technological innovation, project management and civilized construction.


　　The son once puzzled his mother: "People all work in beautiful tall buildings, why does dad always drill into that dark hole?"


　　The mother jokingly said to her son, "Dad, it belongs to pangolin. If you don’t let him dig a hole in the ground, he will suppress something wrong."

Fuel consumption prefix 3, acceleration 6.9 seconds, test drive 2025 BYD Han DM-I.

Comment on 2025 Chinese DM-i in a word:

Balance and maturity are the important selling points of new cars, and the future of Han without obvious shortcomings can be expected.

Advantages:

1, equipped with the fifth generation of DM technology, power loss and fuel consumption 3 prefix.

2. The ride comfort in the back row is good

3. DiLink 100 has strong functionality.

4. The top model has the eye of DiPilot 300 God.

5. The acceleration of all models is 6.9s

Insufficient:

1. We haven’t used the latest design of Chaowang.

2. Only high-profile models have leather seats.

Our test drive this time is 2025 Han DM-I. If you just look at the picture of the front face, you may think that I am wrong. Isn’t this Han EV? One of the changes in the design of the 2025 BYD Han DM-i is the replacement of the same inductance dragon face as the Han EV model, and the front face design is more concise. At the same time, the new car also provides a blackening kit, such as the chrome trim in the center of the front face, and the bottom air inlet and heat outlet are blackened.

Experience Toyota Flanders： Exquisite appearance, full 2.0L power, and good space performance.

Recently, Toyota’s brand-new compact SUV—, Fenglanda, has been officially released. The new car is built on TNGA-C platform and has a good performance in design and space performance. Today, we will experience this model in detail.

In terms of appearance, we can see that the overall design of the new Flanders is very exquisite and the design ideas are also very distinctive. The shape of the front of the car is very recognizable. The sides and bottom of the logo are closed, while there is a horizontal air inlet above. The area surrounded by the bottom is very large, and it is equipped with a lattice air intake grille, which further enhances the fashion sense of the front. The headlights are designed in a layered way, and the recognition after lighting is very high.

In terms of body size, the Flanders have a length, width and height of 4485/1825/1620mm and a wheelbase of 2640mm, respectively, and are positioned in a compact SUV.

The workmanship continues Toyota’s consistent standard, with exquisite workmanship and even seams.

In the part of seat space, the overall performance of Feng Landa is still good. The shape of the seat is relatively wide, and the overall filler is thick and comfortable. In the space part, when a passenger with a height of 1.8 meters in the front row rides, after the seat is adjusted to the lowest position, there is still room for one punch in the head, while after the passenger with the same height enters the back row, the head space is three fingers and the leg space is two fingers, which is enough for most family users.

In terms of power, Fenglanda is equipped with a 2.0L naturally aspirated engine with a maximum power of 171 HP and a maximum torque of 205 N m. The gearbox is equipped with a CVT continuously variable gearbox that can simulate 10 gears. The official WLTC comprehensive fuel consumption is 6.13-6.16L/100km. The suspension part is a combination of the former McPherson independent suspension and the trailing arm torsion beam dependent suspension.

Judging from the overall performance of Guangzhou Automobile Toyota Fenglanda, it is not bad for those home users who pay attention to space. The exterior and interior have a good sense of exquisiteness. At the same time, the power combination of 2.0L+CVT, which is standard in the whole system, can also meet the daily travel use. The performance of the space, especially the performance of the rear space, is good, plus the starting price of 125,800 yuan. It is a very noteworthy model.

20 fatal shortcomings of Volkswagen LaVida, why can’t you buy Volkswagen LaVida？ Tell you today

As a popular family car model, it is deeply loved by consumers. However, like any model, Volkswagen also has some shortcomings. This paper will list 20 fatal shortcomings of Volkswagen LaVida from many aspects, such as space comfort, reliability, maintenance and so on, to help consumers understand this model more comprehensively.

Although Volkswagen LaVida is relatively large in overall body size, the legroom of its rear passengers is relatively small. For consumers who need to ride in the back row frequently, the comfort may be affected to some extent.

The seat adjustment function of Volkswagen LaVida is relatively simple, lacking some advanced adjustment functions. This may limit the individual needs of passengers in terms of riding posture and comfort.

The storage space of Volkswagen LaVida is relatively small, especially in the trunk. This may limit the flexibility of passengers in carrying luggage and shopping, which is not practical enough.

Although the power of Volkswagen LaVida is not bad, its power performance may be average compared with some competitors. The power output during acceleration and climbing is relatively smooth, which may not satisfy the pursuit of driving pleasure and passion.

The suspension system of Volkswagen LaVida is relatively hard to adjust, which may affect the ride comfort, especially when dealing with potholes or bumpy roads.

The safety configuration of Volkswagen LaVida is relatively general, and it may lack some advanced safety functions and auxiliary systems, such as active brake assistance and blind spot monitoring. For consumers with high requirements for improving driving safety, they may need to consider other models.

Although Volkswagen LaVida has made some optimizations in engine technology and power transmission system, compared with some competitors of the same level, its fuel consumption may be slightly higher, which will increase the use cost.

The design of Volkswagen LaVida is relatively conservative, lacking unique design elements and fashion sense. If consumers have higher requirements on the personalization and attractiveness of vehicle appearance, Volkswagen LaVida may not be the best choice.

The rear seat function of Volkswagen LaVida is relatively simple and cannot be folded or adjusted, which limits the flexibility of passengers in storage space and ride comfort.

Although Volkswagen LaVida performs well in terms of stability and maneuverability, its maneuverability may be slightly inferior to that of some competitors. If consumers have higher requirements for vehicle handling performance, they may need to consider other models.

Some consumers report that LaVida is relatively noisy when driving at high speed, especially in terms of wind noise and tire noise. Consumers who have high requirements for vehicle noise control may be dissatisfied with this.

Volkswagen LaVida has relatively few optional configurations and cannot be customized according to individual needs. If consumers have higher requirements on the choice and personalization of vehicle configuration, they may need to consider other models.

Some consumers report that the air output of the rear air conditioner of Volkswagen LaVida is small, which will affect the comfort of the rear passengers.

The rear passengers of Volkswagen LaVida can’t easily use USB interface to charge or connect devices. In modern society, it may be inconvenient for users who have multiple passengers using electronic equipment at the same time.

Some vulnerable parts of Volkswagen LaVida, such as brake pads and clutches, have high maintenance costs. This may increase the cost of vehicle maintenance and maintenance.

The interior design of Volkswagen LaVida is relatively conservative, lacking innovation and individuality. This may not meet the requirements of consumers with high interior design style.

Some consumers report that LaVida has some limitations in driving vision, and the front and rear views may not be wide enough.

The remote control key function of Volkswagen LaVida is relatively few, which may lack some convenient functions when approaching the vehicle, such as one-button start.

Volkswagen LaVida’s body warranty period is relatively short, which may have a certain impact on consumers’ after-sales protection.

Twenty, the price is relatively high:

Compared with some competitors at the same level, the price of Volkswagen LaVida is higher. For consumers who pay attention to cost performance, they may have to pay a certain premium.

Although Volkswagen LaVida is a family car model favored by consumers, it also has some fatal shortcomings from the aspects of cramped rear space and general power performance, limited safety configuration and general noise control. When purchasing LaVida, consumers should comprehensively consider its advantages and disadvantages and make the most suitable decision according to their personal needs and preferences.

R7 price 259,800, pure electric world challenger officially launched

　　On September 24th, at Huawei’s autumn full-scene new product launch conference, Hongmeng Zhixing’s first coupe SUV Zhijie R7 was officially launched, and the new car price was 259,800 yuan – 339,800 yuan. Zhijie R7 shows super product power through excellent appearance design, large space, long battery life and many Huawei black technologies, and is expected to become the next popular model of Hongmeng Zhixing.

　　In appearance, the Smart R7 adopts the body design of a coupe SUV, and the rear of the car is raised, allowing the rear passengers to have more head space, taking into account the appearance and practicality. In terms of details, the new car follows Huawei’s design principle of "extreme, simple and pure". The star track fusion light group on the front face plus the external active air intake grille, and the 3D energy crystal penetrating light at the tail, which is full of movement. At the same time, the smooth body lines, combined with the hidden door handle and blackened sports tail wing design, make the new car have an ultra-low drag coefficient of 0.219Cd.

　　Intelligent experience has always been the advantage of Hongmeng Zhixing products, and Zhijie R7 is no exception. First of all, on the smart drive, the vehicle will be fully equipped with the HUAWEI ADS 3.0 high-end intelligent driving system. We have already had a preliminary understanding of the strength of this system on the Enjoy S9. The application of the new end-to-end architecture not only allows the vehicle to significantly improve in NCA smart driving, active safety, automatic parking, etc., but also allows the vehicle to have the ability to cover the whole scene. From the Enjoy S9, we can also see that the current Huawei smart drive has been able to achieve autonomous driving capabilities from parking spaces to parking spaces, and the decision-making is also more anthropomorphic, bringing the experience of using the smart drive system to a new level.

　　In addition, the new car is also equipped with Hongmeng Cockpit 4.0, which has a rich application ecosystem far exceeding that of the same class of models. At the same time, the Smart R7 also supports HUAWEI MagLink multi-terminal interconnection, and the big model blesses smarter Xiaoyi, making the cockpit interaction more anthropomorphic. In terms of cockpit space, the rear legroom in the car reaches 956mm, and the head space reaches 1034mm, bidding farewell to the cramped and crowded SUV of the coupe. The rear also supports 27 ° -37 ° stepless electric adjustment and ventilation, heating and massage functions. 3.8L & 3.5L double storage drawers are also set under the seats, which is very convenient.

　　It is worth mentioning that the Zhijie R7 is the first SUV model of Hongmeng Zhixing to be equipped with a co-pilot zero-gravity seat. The zero-gravity seat has 18-way seat adjustment and leg support heating, and supports continued reclining to 137 °, allowing passengers to lie down completely. At the same time, thanks to the large rear space, when the co-pilot zero-gravity seat is opened, the rear seat still has a good space performance.

　　In addition to the smart driver and the smart cabin, the "full blood" Tuling platform is also the highlight of the Smart World R7. The new car is equipped with active intelligent curve control, intelligent downhill cruise, and active anti-skid control functions, which have strong capabilities in three aspects: easy driving, safety, and comfort. In terms of hardware, the new car adopts front double fork arms + rear five-link independent suspension, and the whole system is equipped with continuous variable damping shock absorber and air suspension as standard. With the support of air suspension, the maximum height adjustment range of the Smart World R7 body is plus or minus 50mm, which can maintain good passability while improving vehicle vibration avoidance performance. From the previously released closed-beta video, it can be seen that the Smart R7 has shown an outstanding performance in the face of various light off-road scenarios such as continuous steep slopes, deep pit steep slopes, pebble roads, twisted roads, and shell craters.

　　In terms of battery life, the intelligent R7 will be equipped with Huawei’s new DriveOne 800V silicon carbide high voltage platform and Huawei’s giant whale 800V high voltage battery platform, with a maximum battery life of 802km, charging for 15 minutes can supplement 400 kilometers of battery life, and then cooperate with the national 80,000 + cooperative charging network, which can completely eliminate consumers’ battery life and energy anxiety.

　　Looking back at the first half of this year, Hongmeng Zhixing’s success is obvious to all, especially in the field of SUVs. The Q M7 and Q M9 have become the benchmark products in their respective price points. The Q R7 is also on the trend of becoming a hit, and it has won more than 30,000 orders in a small order time of two weeks. We have reason to believe that the new car will become a strong competitor of Model Y with the product advantage of the vehicle itself, reshaping the competition landscape of 25-350,000 pure electric SUVs.
