Next, look at the camera part. Although the iPhone 14 Pro/Pro Max series is still a three-camera scheme with super wide angle+wide angle+telephoto, and equipped with a LiDAR lens, the main camera is upgraded to a brand-new 48-megapixel sensor for the first time, with a unit pixel area of 1.22μ M, supporting the four-pixel integration technology, and the unit pixel area can reach 2.44μ M, the lens aperture is f/1.78, the lens focal length is 24mm, and it is equipped with the second generation sensor displacement anti-shake technology. However, on the ultra-wide-angle and telephoto lenses, they still maintain 12 million pixels, the equivalent focal length of telephoto lens is 77mm, and the equivalent focal length of ultra-wide-angle lens is 13 mm.

In terms of camera module size, the camera module size of iPhone 14 Pro is slightly larger than that of iPhone 13 Pro.

Disassemble the camera module, you can see the main camera sensor of iPhone 14 Pro, and continue to adopt the sensor shift image stabilization system first introduced by iPhone 12 Pro series, which greatly improves the anti-shake performance. In terms of the size of the main camera sensor, the iPhone 14 Pro has been expanded from 1/1.67 inch of the previous generation to 1/1.31 inch.

Compared with the previous generation, the rear lidar module of iPhone 14 Pro only has a slight change in cable design.

Although the "Microcomputer Branch" does not indicate the suppliers of the lens module, image sensor and laser radar module of the iPhone 14 Pro series, according to the previous data, the rear lens module of the Pro series should be mainly supplied by Dali Light, and the image sensor is mainly supplied by Sony. The rear lidar module is mainly supplied by Sony. As for the front Face ID module, the Face ID of iPhone 13 series was previously supplied by Foxconn and LG Innotek, but the Face ID of 14 Pro series has been improved, so it is uncertain whether it will still be supplied by these two companies.

There is a dustproof and waterproof apron around the inside of the rear flash of iPhone 14 Pro, which is quite different from the previous generation. After violent disassembly, it can be seen that the rear flash of iPhone 14 Pro has changed from two bulbs in the previous generation to a big bulb, but Apple has divided it into nine parts, which can adaptively control the flash intensity, brightness and uniformity. Both have improved.

The bottom speaker module of iPhone 14 Pro is basically the same in size as the previous generation.

Although the motor size of iPhone 14 Pro has shrunk compared with the previous generation, the external specifications close to 0920 are still excellent.

The sub-board structure at the bottom is the same as the previous generation, which is integrated with barometer, two microphones and a charging port. There is a dustproof and waterproof rubber ring on the inner side of the bottom speaker window.

In terms of battery, the iPhone 14 Pro series is still an L-shaped battery. From the perspective of the National Bank version disassembled by "Microcomputer", the battery capacity of the iPhone 14 Pro is 3,200 mAh, which is 105 mAh higher than that of the previous generation. The supplier is Huizhou Desai; The battery capacity of iPhone 14 Pro Max is 4323 mAh, which is 29 mAh less than the previous generation. The supplier is Xinwangda.

△iPhone 14 Pro battery information

△iPhone 14 Pro Max battery information

There are some parts on the back shell of the iPhone 14 Pro series, and the structure has been slightly adjusted. The WiFi antenna and NFC antenna are integrated on a flat cable, and the physical buttons and wireless charging module are integrated as in the previous generation.

Summary:

Judging from the above disassembly report and the existing public information,Although the hardware configuration of the iPhone 14/14 Pro has not been greatly upgraded as that of the Pro series, its internal structure has been redesigned, and the "sandwich" design has greatly improved the maintainability.

Therefore,IFixit gave a high score of 7 (out of 10) for the repairability score of iPhone 14, which is also the highest score since iPhone 7. IFixit even said: "This is a big event, and Apple should make a major statement that the iPhone 14 has been redesigned from the inside out to make it easier to maintain."

Sam Goldheart of iFixit thinks: "In this era, product launch should not just brag about some small new features. Why doesn’t Cook brag about repairability? We didn’t know this would happen because Apple didn’t mention it at all. But they should do so. "

In addition, the two-way satellite communication function introduced by iPhone 14 series is also a focus of attention. The reason why the iPhone 14 series can support two-way satellite communication is mainly due to the upgrade of Qualcomm Snapdragon X65 baseband chip and Apple’s self-developed RF antenna.

According to previous data, Qualcomm Snapdragon X65 baseband chip can not only support the downlink rate up to 10Gbps, but also cover all major 5G bands including millimeter wave and Sub-6GHz band and their combinations. It is confirmed that the satellite communication of iPhone 14 series is supported by Qualcomm Snapdragon X65. The baseband chip has added a new 2.4 GHz n53 band function to support the satellite of Globalstar, a satellite communication company cooperated by Apple.

ICJay Monroe, executive chairman of Globalstar, boasted at the press conference earlier this year: "We appreciate the close relationship with Qualcomm since the company was founded, and thank their team for their hard work in helping us realize the promise of Band n53." Globalstar previously announced that it agreed to use 85% of its current and future satellite network capacity to support the two-way satellite communication function of iPhone.

In addition, the addition of two-way satellite communication function, coupled with many existing communication functions such as 5G, WiFi, Bluetooth and GPS, not only greatly increases the number of antennas, but also brings greater challenges to antenna design. During the disassembly, we also saw some new designs of Apple on the antenna.

Disassembly also shows that although the iPhone 14 Pro series still uses 6GB of memory, it uses the latest LPDDR5 technology, while the previous generation iPhone 13 series is LPDDR4X.

Earlier, Apple had indicated that it would not consider using Changjiang storage flash memory in iphones sold in markets outside China, so we didn’t see the version using Changjiang storage flash memory in the disassembly of the US version of iFixit iPhone 14 series.

However, the three National Bank versions of the iPhone 14 series dismantled by Calculus have not found any flash memory with Yangtze River storage. But,According to the disassembly video of the National Bank version of iPhone 14 Pro Max released by a domestic blogger, the disassembled version uses flash memory supplied by Changjiang Storage.

Judging from the changes in the supply chain of Apple’s iPhone in recent years, the proportion of Chinese mainland suppliers in the Bank of China version of iPhone is growing continuously.

This may also be a measure taken by Apple to reduce the supply chain risks caused by the "US-China science and technology war" and "geopolitical issues".

Original title: 360′ s fast video APP releases short videos and is about to usher in the era of quality content.

In the past year, the short video industry has developed rapidly, and short video has become a new direction of investors’ attention. However, short video platforms emerge one after another, which is too demanding for quantity rather than quality, which directly leads to the difficulty in controlling short video content, and the quality of short video content has become the key to the development of short video industry.

Photo: 360 founder and CEO Zhou Hongyi delivered a one-minute speech.

On November 14th, 360 Express Video held an ultra-short video app-Express Video Conference in Beijing. At the conference, Zhou Hongyi, founder and CEO of 360 Group, gave a short speech for one minute, proposing to watch the video for one minute, so that every second of the video will be more exciting and busy people can watch interesting and informative videos in the shortest time.

A one-minute story only looks at the essence, only the essence.

As the first ultra-short video APP in the whole network, Fast Video has specially created a "1-minute series" column, which clips the wonderful scenes of film and television works to one minute, allowing users to watch the wonderful contents of the current wonderful film and television works in one minute, and quickly obtain the key points of the long drama series, compressing the entertainment time to one minute, but expanding the entertainment effect to the satisfaction of users.

One minute of ultra-short video naturally can’t make users wait for time. 360 Fast Video introduces the functions of fast playing and fast preview of ultra-short video, allowing users to see the climax of ultra-short video in one second, without wasting a minute or a second of entertainment time.

Fast video each video is only one minute long, which makes users worry about the integrity of the video story. Fast Video Select short videos with high quality for 1-3 minutes, and compress the story so as to finish a story in one minute.

Based on the background of 360 big data and artificial intelligence, Fast Video adds leading image vision artificial intelligence technology on the basis of other video platform technology reserves, and each released video is screened by the technical background, so that every work pushed to the client has quality and connotation, and can tell a story completely. Let users capture the wonderful in one minute and appreciate the wonders of the world in one minute.

Intelligent exploration engine helps users explore new fun.

The most common browsing mode of short video platforms is to push the updated content in the background immediately. Users browse in real time, and the video label is not obvious. Users often receive content that they are not interested in, so they can only skim over the uninterested content and skip to the next one.

Fast Video is a new generation of QVD intelligent exploration engine, which senses and records users’ emotions every time they browse video content, and analyzes users’ preferences through the background system. When the user browses the short video content next time, the background will be pushed to the client according to the user’s preference.

In addition to analyzing the length of time users watch videos, the free search function of fast videos is also one of the ways for the system to obtain users’ preferences. The fast video system strengthens the user’s emotional perception and free exploration, so that users can not only see interesting content, but also find other kinds of wonderful videos, bringing more excitement to users’ entertainment time.

Improving the quality of short video from the production team

The quality and connotation of short videos are inextricably linked with short video producers and teams. In order for users to watch fresher and better quality video content, Fast Video pays special attention to the video team.

Up to now, the fast video team has settled in tens of thousands of original video organizations and teams. At the same time, Fast Video said that Fast Video will invest 10 billion yuan to build an ultra-short video ecosystem and set up a fast fund plan.

In order to support video producers with ideas, but the technology is not up to standard for the time being, Fast Video provides a permanent and free editing tool-Fast Editing, aiming at providing a broader growth space and more lucrative returns for each video author.

Fast video starts with video content and strives to create an ultra-short video APP with high quality. It is worth looking forward to whether the fast video can enhance the awareness of short video platform content.

The number of netizens is 1.051 billion, and the Internet penetration rate is 74.4%-this is the latest statistical data on the development of Internet in China.

Huge netizens constitute a booming consumer market in China, laying a solid user base for the development of digital economy, and at the same time putting forward higher requirements for network security.

From September 5 to 11, 2022 National Cyber Security Publicity Week was held. This year’s publicity week will further popularize important laws and regulations such as the Network Security Law of the People’s Republic of China and the Data Security Law of People’s Republic of China (PRC), and promote network security knowledge and skills.

Without network security, there will be no national security, no stable economic and social operation, and it is difficult to protect the interests of the broad masses of the people.

General Secretary of the Supreme Leader stressed that the national cyber security work should adhere to the principle that cyber security is for the people and cyber security depends on the people, ensure the security of personal information and safeguard the legitimate rights and interests of citizens in cyberspace.

At present, telecommunication network fraud has become the crime type with the largest number of cases, the fastest increase, the widest coverage and the strongest response from the people. In May this year, the Ministry of Public Security announced five types of high-incidence telecommunication network fraud cases-single rebate, false investment and wealth management, false online loan, impersonating customer service and impersonating public security law. These five types of fraud accounted for nearly 80%.

Telecom fraud is fascinating, how to strengthen prevention and crack down on criminal behavior more accurately?

On September 2nd, the 13th the National People’s Congress Standing Committee (NPCSC) Conference voted to pass the Anti-Telecommunication Network Fraud Law of People’s Republic of China (PRC).

As a "small-cut" special legislation, the anti-telecommunication network fraud law, on the basis of summing up the experience of anti-fraud, focuses on strengthening the construction of preventive legal system, increasing the punishment for illegal criminals, and promoting the formation of a control pattern of anti-fraud, anti-fraud in the whole chain, anti-fraud in the whole industry and anti-fraud in the whole society.

Netizens have received rave reviews. "Internet life needs this sense of security."

Many people have seen the online rumor that "dead birds spread monkeypox virus" and "Huoxiang Zhengqi water can prevent heatstroke". Some online rumors with "nose and eyes" are hard to distinguish between true and false, and many people have been fooled.

On April 19, 2016, at the symposium on network security and informatization, General Secretary of the Supreme Leader emphasized: "Those who run websites should not blindly pursue click-through rates, those who open online stores should guard against counterfeiting, and those who do social platforms should not become rumor spreaders, and those who do search should not be ranked only by the amount of money."

In response to the "various" online rumors, recently, the Central Network Information Office launched a nationwide special campaign to "clear and crack down on online rumors and false information".

The special action will improve and perfect the rumor mechanism. This mechanism studies and improves the algorithm recommendation rules, and accurately pushes relevant rumor information to users who have been exposed to rumors and false information to improve the rumor effect.

The "big move" to improve network security is not limited to this.

On June 1, 2022, the cyber security law was officially implemented for the fifth anniversary. This basic law in the field of network security clearly stipulates the protection of personal information, the control of network fraud, the protection of key information infrastructure and real-name registration system, which has become an important milestone in the construction of cyberspace rule of law in China.

In view of the rampant black industrial chain of the Internet and the high incidence of network-related crimes, the "Net Net" action thunderstruck …

In order to make people feel more at ease online, China has built a firewall for network security from multiple dimensions.

Scan code to get small gifts, "bargain" for free goods, and "surfing the Internet" can save traffic … Behind these behaviors, there may be hidden crises.

Maintaining network security is inseparable from the active participation and initiative of every netizen.

Since 2014, China has held the National Cyber Security Publicity Week for nine consecutive years, which has effectively promoted the promotion of cyber security awareness and protection skills of the whole society; All kinds of network security publicity, so that netizens can master the corresponding network security skills; Online and offline online cyber security Expo theme exhibition, people can learn about new products and demonstration applications …

Network security awareness should always be "online", and surfing the Internet can be more secure.

The General Secretary of the Supreme Leader pointed out that it is necessary to adhere to the integrated development of cyber security education, technology and industry, and form a benign ecology of talent training, technological innovation and industrial development.

In recent years, China has not only built an effective network security system, but also taken a series of measures to promote the training of network security talents.

The Opinions on Strengthening the Discipline Construction and Personnel Training of Cyber Security was issued, and a first-class discipline of Cyberspace Security was established, and a demonstration project for the construction of a first-class cyber security college was implemented.

As of June this year, more than 60 universities in China have set up cyber security colleges, and more than 200 universities have set up cyber security undergraduate majors, with more than 20,000 cyber security graduates each year.

We will build a national network security talent and innovation base, promote the agglomeration and development of network security industry, and make breakthroughs in network security core technologies … Under the concerted efforts of all parties, the co-governance and co-construction of network security is getting better and better.

Network security is for people, and network security depends on people. Together, we will build a network security defense line, and the people’s sense of acquisition, happiness and security in cyberspace will continue to improve.

Original Dr. Ni from NiNi, Florida, in the United States.

After this year’s college entrance examination mathematics examination paper came out, there was a cry of bitterness on the Internet. As an American math teacher, I also looked at it curiously. Frankly speaking, it can only be described in one word: Meng.

There is no college entrance examination in the United States, only the SAT or ACT exam similar to the college entrance examination. My son, who is in senior three, took a naked SAT math test this year, with a total score of 800 points and a score of 740. This achievement ranks among the top 5% in the United States, and he still has one year to graduate (four years in American high school). Is it difficult to ask him a question? He said it was very simple, and all the tests were the most basic contents.

Compared with Chinese college entrance examination mathematics, what are the characteristics of American SAT mathematics?

1. Most of the topics are multiple-choice questions.

The mathematics part of the SAT is 80 minutes, with 58 questions, of which 45 are multiple-choice questions, and only 13 need to fill in the answers by themselves. The latter will be a little more difficult because it is easier to make mistakes.

I have taken several exams in the United States, and most of them are single-choice questions. The advantage of multiple choice questions is that you can guess the answer, and the error rate is also lower. For example, if there is a slight deviation in the calculation, you will find that there are no required options in the answer and you can’t check it again. Comparatively speaking, there are four kinds of math problems in China’s college entrance examination: single choice, multiple choice, filling in the blanks and solving problems, especially the last kind of solving problems, which needs to be reasoned, proved and solved step by step. It is really not easy.

2. Pay more attention to basic concepts

From the topic, American SAT mathematics pays more attention to the understanding of basic concepts.

The figure below shows the SAT’s examination of mathematical ability. It is divided into four categories, including core algebra, problem solving and data analysis, introduction to advanced mathematics, and other mathematical topics. The last item is related to interdisciplinary topics of mathematics and social sciences.

Taking the introduction of advanced mathematics as an example, the required abilities are: 1) identifying and creating algebraic equations; 2) Create, analyze and solve quadratic equations and other nonlinear equations fluently; 3) Create, use and draw charts of exponential equations, quadratic equations and other nonlinear equations. None of this exceeds the content of algebra 2.

Here are two sample questions to give you a rough idea of the difficulty.

3. The weight of SAT in American college entrance examination

Compared with the official nature of China’s college entrance examination, the American SAT is set and evaluated by the third-party university committee of the non-profit organization. Different from the Chinese college entrance examination, the admission of American universities depends on the GPA, specialties, community activities, community services, and application documents of students in high schools. The SAT is only used as a reference.

In recent years, American educational circles have been debating whether to cancel the SAT, but so far, the SAT is still a very important reference. If you do well in the exam, you will still have a considerable advantage in college admission.

Another difference of SAT is that you can take it many times and get the highest score. The following is the examination time for the 2022-2023 school year. In one school year, there were seven examination opportunities. Therefore, even if you don’t do well in the exam for a while, you won’t feel that the end of the world is coming. Just take the exam next time.

4. Emphasis on concepts in American mathematics teaching.

American mathematics teaching attaches great importance to concepts. One feeling is that sometimes I have to spend a lot of time teaching vocabulary. For example, there are as many as 12 words in the chapter of teaching geometric figure changes, and teaching vocabulary often becomes a difficult problem: how can students understand and remember it more easily?

For another example, American teachers attach great importance to the process of teaching unary equations.

I remember when we were in China, we learned to move all variables to the left and numbers to the right, but we had to change the sign. The United States emphasizes the meaning of "equation", and all operations should not exceed the line of "equal sign". Add a number to the left and a number to the right, as well as multiplication and division, so as to maintain the balance on both sides of "equal sign". Compared with mathematics teaching in China, it is much more complicated, but easier to understand.

Therefore, I take the best of both, teaching with the American method, and doing my own problems with the China method, because it is much faster.

Look at Chinese’s criticism of the deviation of the math college entrance examination questions, while Americans are also criticizing their math education problems, and some also compare China and think that American math education is much behind China. In my opinion, there are only different ideas, and each has its own views on which is better or worse.

Do you prefer the math college entrance examination in China or the SAT math exam in the United States? Welcome to vote. Also welcome to leave a message for discussion.

The 2024 Beijing Auto Show will be officially opened on April 25th, and it has been less than a month. The previous Beijing Auto Show was not held as scheduled due to the epidemic, so all the major auto companies in this auto show are gearing up, saying that Sir will help you summarize the heavy cars at this auto show in two phases. Without further ado, let’s start the first one.

• Brand new magotan

The brand-new Magotan is a replacement model. As a brand-new replacement, the appearance and interior of the car have adopted a new design, in which the appearance has become younger and more fashionable, and it is no longer a business style. Headlights are sharper in shape, with a penetrating light strip and a luminous Logo in the middle. The side lines are very regular, the shape is very capable, and there is a long waistline in the middle, which looks very powerful. The tail adopts a penetrating light strip, and the interior is dot matrix layout. In addition, there is a duckling tail above. In terms of size, the length, width and height of the new Magotan are 4990/1854/1487mm and the wheelbase is 2871mm, which is larger than the current Magotan.

The interior adopts the design of triple screen, which has a stronger sense of technology. From the picture, the car is designed with a fender, the UI interface of the car is very simple, and the operation should be more convenient, and it is also equipped with the intelligent driving scheme newly released by DJI.

Power will be provided in 1.5T and 2.0T versions, in which the maximum power of 1.5T engine is 118kW, while that of 2.0T engine is 162kW, which can meet the needs of different consumers.

• Qin l

Qin L is a new member of the BYD Dynasty series. This car is positioned as a compact car, which is larger than Qin PLUS and has a higher configuration. It is equipped with a DM-i5.0 hybrid system. It seems that BYD has to enlarge its tricks again.

The overall appearance of BYD Qin L is similar to that of Song L, adopting a brand-new family-style design style, and its biggest feature is young sports. Headlights are flat in design, with a bent light strip at the eyebrow eye and a black plaque in the middle with a very conspicuous word "Qin" on it. At the bottom is a large-size air intake grille, with a lattice layout inside and air intakes on both sides, so the sports atmosphere of the whole front face is very strong. The side adopts double waistlines to make the body look slimmer. The tail is equipped with a penetrating taillight, which is very recognizable after lighting, and there is a large diffuser below, further highlighting its sports atmosphere. In terms of size, the length, width and height of the car are 4830/1900/1495mm and the wheelbase is 2790mm, which is larger than Qin PLUS, but smaller than Seal DM-I..

The interior design is similar to Song L’s, including a two-color interior, a three-position steering wheel, two large screens and a crystal bumper.

The power will be equipped with a DM-i5.0 hybrid system, which consists of a 1.5T+ motor. The maximum power of the engine is 74kW, and there are two kinds of maximum power of the motor, namely 120kW and 160kW. There are three versions of pure battery life, which are 43km, 60km and 90km respectively, and the fuel consumption is 3.8L/100km.

• Xiaomi SU7

Everyone should be familiar with Xiaomi SU7. Its appearance is very sporty, and its overall design is a bit like that of Porsche Taycan. The headlights are shaped like water droplets, and the internal structure is a "meter", which is very recognizable. In addition, there are 17 tuyeres and 8 sets of air ducts in the whole car, which incorporate many aerodynamic designs. The side lines are smooth and dynamic, coupled with the low-lying shape and plum blossom wheels, the overall sports atmosphere is very strong. Star-ring taillights are used at the tail, with tuyeres on both sides, and Xiaomi SU7 also has an electric tail, which supports 4-speed adjustment and can provide up to 130 kilograms of downforce.

The interior provides a 7.1-inch full LCD instrument that can support overturning and a 16.1-inch central control panel. The car is powered by Xiaomi’s surging OS system, matching Qualcomm Snapdragon 8295 chip. It also supports mobile phone application pin to the car, more than 1,000 kinds of mijia devices get on the car without induction, and more than 5,000 applications are gradually adapted, so the ecology of Xiaomi SU7 is very strong.

Xiaomi SU7 has two kinds of power: single motor and double motor. The maximum power of the rear-drive single motor is 220kW, and the zero acceleration is 5.28s and 5.7s, while the maximum power of the dual-motor version is 495kW, and the zero acceleration is 2.78s s.. In terms of battery life, there are three versions of the car, and the CLTC battery life is 700km, 830km and 800km respectively (dual-motor version).

• Jiyue 07

Extreme Yue 07 is the second car owned by Extreme Yue Automobile. The front face of the car is basically the same as that of Extreme Yue 01. The middle net is closed, and the two sides are equipped with very sharp lights, which is very recognizable. The front of the car will press down further, creating a more diving visual effect. The side is designed with a slip back, and the lines are very dynamic. Coupled with the design without a door handle, the whole side looks very smooth and tidy. The tail adopts a Y-shaped through taillight, and the effect after lighting is very good. In addition, the rear of the car is designed with a hatchback tailgate, which is matched with an electric tail wing to enhance the sports atmosphere.

The interior has not been announced. I’ll report it to you when we get to the auto show. However, in terms of family design, it is estimated that it will be very similar to the Extreme Yue 01, and it will also be equipped with a 35.6-inch 6K integrated LCD screen, which can be divided into two screens and three screens for independent display.

There is no more information about Power, but it is expected that 400V and 800V architectures will be available. I will synchronize the news in time.

Conclusion:

The theme of this year’s Beijing Auto Show is "New Era, New Cars", which highlights the word "new". Major car companies attach great importance to it and bring many new cars. Judging from the four cars introduced above, the exterior design of many cars has become younger and more fashionable, and the interior is becoming more and more scientific and technological. What do you think of this trend? Is it hard to accept or prefer it? Welcome to discuss in the comment area.

Experience: The dynamic performance of the new generation 2.0T is still the same, and the extended sports performance is limited.

　　Except for the higher 3.0, the new generation of Magotan has not been listed yet, and other power sources have remained basically the same. How will the 2.0T new Magotan look at its performance from the eyes of bosses? Let’s take a look.

　　This powertrain can be described as an "old friend". Although there is still a higher-level 3.0FSI powertrain version that has not been released, the 2.0+6 powertrain will definitely not disappoint you in business-class models.

　　This 2.0T model is quite smooth in D-gear mode. After the throttle is slightly slow, the power will be output very smoothly, which is not in a hurry, but it is definitely not a feeling that can’t be used, as long as you are willing to give oil. However, when the S gear is engaged, the new Magotan will be restless, and DSG will drop two gears in a row, which is followed by a strong push-back feeling, and the power output is extremely sharp. However, for leaders who are used to comfortable riding, D-block driving is what they want.

　　The chassis adjustment of the new generation of Magotan tends to be comfortable, but it is still soft, which can better filter the vibration on some bumpy roads like shock absorption belts. This kind of "softness" is the best comfort for the boss.

　　Although the power and chassis adjustment are thinking about the business car that bosses want, the noise reduction that bosses value very much seems to have not made much progress on the new generation of Magotan, which makes bosses start to be a little embarrassed. Magotan can do better in noise reduction.

Supplementary track test drive:

　　Next, we will supplement the test drive experience of the new generation of Magotan in the test site to see how much the extended 100mm wheelbase will change the control of the new generation of Magotan.

　　Through the test drive, we can clearly feel that the poor braking posture of the old Magotan still does not perform well on the new generation models. The new generation of Magotan’s soft adjustment and extended wheelbase make it easy to reach the limit in fierce driving. The suspension is easily compressed to the limit and often involved in work. This is the "disaster" caused by the 100mm extended wheelbase. The new generation of Magotan continues to stay away from sports.

Full text summary:

　　There is no doubt that the new generation of Magotan with longer wheelbase has brought you a brand-new ride experience in the back row. Although it has affected the performance, this compromise is still worthwhile. For those who emphasize business performance, the main consumer groups are elites who are slightly older. For them, the motivation performance is decent enough. As for manipulating these, it is no longer important. From this perspective, the new generation of Magotan does have the capital to meet the needs of these people. (Text, picture, photo/He Yongming)

Pay attention to the differences in details and compare Passat’s new magotan in detail.

It was officially launched in November last year. In order to meet the market demand, the car launched double sniper tactics, and the electric version/hybrid version was launched at the same time. Among them, the three DMH hybrid versions are 121,800-141,800 yuan, and the three EV electric versions are 143,800-170,800 yuan.

Roewe is full of hope when the new car goes on the market. Roewe has previously launched a volume model, but Roewe has not launched a peak product in the later period. According to the data, in 2020, Roewe sold 435,600 vehicles, in 2021, it sold 375,600 vehicles, and in 2022, the overall sales volume of Roewe was 286,000 vehicles, down 23.86% year-on-year. The market share of Roewe has been shrinking, and the decline in sales volume has become the norm. Therefore, Roewe urgently need to launch a volume model to pull itself back to the mainstream track.

However, the reality is cruel. According to the data provided by the Association, the wholesale sales volume of Roewe D7DMH in December was only over 800, and the wholesale sales volume of D7 EV version was only over 700, totaling less than 2,000. This also confirms the prediction of netizens who listed new cars.

For the Roewe D7 car, users generally reflect that the price is too high, so the price is bound to be cool, and the reality is indeed the same.

In addition, the product quality of Roewe Automobile has been frequently complained this year, which has also cast a shadow over Roewe’s brand image and formed a bad reputation.

In appearance, Roewe D7 adopts Roewe’s latest family-style design style. The appearance of the model is different from that of plug-in hybrid. The D7 EV adopts the design of closed front face and split headlights, and the D7 DMH adopts integrated headlights. In terms of body size, the length, width and height dimensions of DMH models are 4890/1890/1510mm, and those of EV models are 4890/1872/1510mm, with a wheelbase of 2810mm.

The interior part, with dual 12.3-inch LCD screens, supports the circulation between the locomotive and mobile navigation, automatic planning of long-distance charging, and effective reply of diverse voices.

In terms of power, the Roewe D7 DMH model is equipped with a plug-in hybrid of a 1.5L hybrid special engine and a motor combination. CLTC has a pure electric cruising range of 125km and a comprehensive cruising range of 1400km. The cruising range of D7 EV CLTC is 510km and 610km respectively, and the acceleration time from 0 to 100 km/h is 7.3 seconds and 6.5 seconds respectively.

On the whole, Roewe D7 performance is not excellent, and the bidding models include BYD and Changan medium-sized cars. Although the Roewe D7 seems to be slightly lower in terms of price, it is not as good as the first two cars in terms of positioning. In addition, the performance of Roewe D7 is not outstanding in terms of power. Naturally, it is not as good as the first two cars. The sales figures can also prove this. Seals sold more than 10,000 vehicles in December and Deep Blue SL03 sold more than 6,000 vehicles. Under the strong pressure of competing models, Roewe D7 will not get much benefit. It is worth mentioning that we saw the E-QM5 in the sales list of medium-sized cars in December, and its wholesale sales in December also reached more than 10,000. It is said that the car has a minimum of 100,000 cars, and the price of 160,000 is 100,000 yuan, so the sales volume will not come up at once. Breaking a bone is better than anything. How fragrant it is! Roewe D7 wants to sell, and its brand positioning can only be considered as the second line, and it is really difficult to sell without fracture promotion.

　　"Am I in a dream? Is it really in a dream? " Wearing a fluffy explosive head and a rainbow-like dress, Rene Liu stepped into the reality of "milk tea" from behind the "door" on the big screen of the stage. Last night, she appeared to be sleepy and boarded the Shanghai stage, thus opening the prelude to the "Daphne 2008 Sleepwalking" Shanghai concert.

　　Virtual-

　　Wu Bai, Zhang Zhenyue and Chen Shengzhu sang One Night in Beijing.

　　Taking "sleepwalking" as the theme of the concert, Rene Liu is bold, as she said: "Here, I can combine reality and virtuality, just like reality and dreams." As a matter of fact, the secret of creating the dream atmosphere just right last night was the three huge big screens in the center of the stage. Not long after the opening, when "milk tea" sang the theme song "Do you know" of the movie "world without thieves", two face-to-face close-ups of Rene Liu’s head appeared on the screen at the same time, which, together with her mouth shape, formed the dreamland of three people singing together, which was very special, but, carelessly, the real person "milk tea".

　　The most amazing virtual scene is the scene of One Night in Beijing. Rene Liu excitedly told the audience that he had invited several heavyweights: "I used technology to bring them together." The words sound just fell and Zhang Zhenyue playing drums and Wu Bai playing the bass appeared on the big screen. With their cooperation, Rene Liu covered A Night in Beijing. Unexpectedly, Bobby Chen, who was holding a microphone, suddenly appeared on another big screen. He sang this masterpiece with "milk tea". The cooperation between a woman and three men from a distance is surprising and creative. More interestingly, Bobby Chen, who was also a teacher and friend of Rene Liu, sang "bitter words" for the last time, and persuaded Rene Liu with the help of lyrics in the song: "You’d better marry yourself well, don’t wait any longer, he won’t come back." The milk tea on the stage seems to be true and false: "You care about me!" This pair of apprentices, whose emotional world is constantly speculated by the outside world, completed an emotional dialogue through virtual space.

　　At last night’s concert, Rene Liu sang those sad love songs again and again. Even when humming "The person you like doesn’t appear" in "Loneliness for a lifetime", she couldn’t help asking "Where are you", but she was always optimistic on the stage and sang "very cool". However, in an instant, she sighed: "Why do girls like me sing so many lonely songs?

　　Truth-

　　Return to sing "Do you know?"

　　At yesterday’s concert, Rene Liu invited Tiger Hu to sing "Journey of Breaking Up". I don’t know if it was caused by nervousness. Tiger Hu, the little king of the mainland who sang with "milk tea" for the first time, actually forgot his words. When introducing another guest, Christine, Rene Liu was full of gimmicks, claiming to invite a prop before singing. The staff then moved to a cushioned elevated platform, where "milk tea" stood and said to the oncoming "Gao Mei" Christine: "I finally know how you feel about me."

　　The pair, dubbed "simple tea and simple rice", tacitly sang "What you can’t tell your lover". In the second half of the concert, Rene Liu changed her previous lady’s dress, put on a white shirt and suspenders, and covered "Stubborn" by Mayday. At the same time, she invited fans to take the stage and sang "Lighting the Orange Tree" together.

　　When returning to the stage, Rene Liu, who has always pursued perfection, replied to the truth in life and told the audience that he would sing "Do you know?": "When singing this song in front of me, I didn’t lip-synch with the people on the big screen. I hope my first concert can be the best."
