Extreme krypton started a sideline: holding the vast -M architecture and building cars for autonomous driving companies.

Does the company have to build cars?

With the mature development of the industrial chain, autonomous driving companies can generally come up with autonomous driving sensor kits specially designed for Robotaxi scenes and in line with in-vehicle applications and standards.

In their view, building a car in the next stage is not only time-consuming and costly, but also has many technical barriers. It also needs to build its own factory and build an upstream and downstream industrial chain.

At the same time, there is another voice in the industry that adding sensor kits, technical units and software to the original vehicles is no longer in line with the next development goal of autonomous driving.

In other words, building a car will become the most critical step in promoting the commercialization of autonomous driving.

In July 2022, Baidu Apollo released the first unmanned vehicle RT6, which broke the dilemma that Robotaxi was mostly a modified car, and the cost of RT 6 was reduced to250 thousandYuan.

On November 17th, 2022, the M-Vision concept car jointly developed by Waymo and Krypton made its debut in Los Angeles. The new car was based on Krypton Vast-M.(SEA-M)The architecture will be mass-produced in 2024 and put into commercial operation in the United States.

In their view, autonomous driving wants to achieve large-scale mass production of technology, vehicle platforms need to be innovated, and software and hardware systems need to be more deeply integrated.

This means that the carrier of autonomous driving needs to draw a blueprint from a blank sheet of paper.

"It is an inevitable trend for unmanned vehicles to develop from refitting and installing finished vehicles to customizing and developing based on vehicle platforms. An industry person said.

01、I started a sideline and built a car for Waymo.

In December 2021, Waymo officially announced a cooperation with Krypton. The latter will provide exclusive vehicles for Waymo’s self-driving fleet and put it into commercial operation in the United States.

A year later, the M-Vision concept car, the result of cooperation between the two parties, made its debut in Los Angeles.

According to the heart of the car, Waymo is responsible for the automatic driving system and cockpit entertainment system, while the European Innovation Center is responsible for providing the core components of Robotaxi.Vast -M architecture.

In fact, Krypton was able to cooperate with Waymo without two acquisitions.

In July 2021, it was extremely embarrassing.1,057.8 millionkoruna(about 799 million yuan) Acquired CEVT in Gothenburg, Sweden(China-Europe Technology Research and Development Center)100% equityLater, it was renamed the European Innovation Center.

After the acquisition, CEVT can provide shared architecture, chassis, powertrain, transmission system, car body and vehicle design technology for future strategic products and R&D platforms.

CEVT is a gathering place of technical souls.

Since its completion and operation in 2013, CEVT has been Geely.1.3 millionThe production and sales of this car provide a complete and systematic technical system, and have trained thousands of global technical talents. The well-known CMA architecture and so on are all from this R&D center.

The second acquisition comes from the 30% equity acquisition of vast energy. This acquisition enables Krypton to redevelop the vast architecture of SEA.

In short, combined with the technical advantages of Krypton European Innovation Center, Krypton can develop the vast architecture again-this is also the origin of the vast -M architecture.

Vast -M is developed based on the vast architecture of Geely SEA, which took Geely five years to invest.20 billionThe pure electric architecture developed is also the killer of Geely in the field of new energy.

The characteristics of Geely’s vast architecture can be simply summarized into three key words:

According to Krypton, Haohan -M is the world’s first intelligent mobile travel platform specially developed for autonomous driving scenes, and it is the latest type of vast architecture facing the era of autonomous driving.

Among them, the m of vastness -M stands for Modular Mobility Architecture(Modular Travel Architecture).

On the basis of prototype architecture, Vast -M passedhardware layer+System layer+Ecological layerTo create a sustainable and extended self-driving vehicle.

To achieve this, we not only rely on the vast prototype architecture to cover the high application range of 1800-3300mm wheelbase of A-E class cars, but also need a native electric platform and flexible expansion ability to support L4 class automatic driving.

In this regard, it is almost impossible to achieve the traditional fuel vehicle platform, and related problems have been exposed in oil-to-electric vehicles before.

Constrained by a large number of complicated mechanical transmission structures, the expansion and layout adjustment capabilities of the traditional fuel vehicle platform are very limited, and the motors can only be installed in the space left after the fuel tanks are cancelled, so it is difficult to adjust the vehicle structure.

It can be said that holding the advanced vast -M architecture, he started a sideline business-helping autonomous driving companies build cars, which directly contributed to Waymo’s choice of cooperation.

Vast -M architecture, fully embedded with automatic driving interface, can be connected to the automatic driving system of L4 level and above, and can be compatible with different automatic driving schemes, from local control to full control of vehicles.

In addition, the vast -M architecture meets all technical requirements of autonomous vehicles and is compatible with all autonomous driving schemes.

"From Waymo’s point of view, it is extremely difficult for Krypton or Geely Group to find a second partner because of its ability to control costs under the same quality and its European R&D and innovation capabilities. 」

When talking about why Waymo chose to cooperate with Extreme Krypton to develop customized cars, Yang Dacheng, vice president of Extreme Krypton, said.

"The vast -M architecture is open to ecological partners around the world, not just Waymo, but also other global autonomous driving companies."

Through the cooperation case with Waymo, Yang Dacheng also threw an olive branch of "OEM" to other autonomous driving companies.

In the past, the threshold of "OEM" was not high, just providing enough assembly experience to achieve the production target.

Nowadays, due to the special products such as self-driving cars, the traditional cooperation mode is directly broken, and at the same time, the "OEM" needs to export certain research and development capabilities.

02、What’s different about Robotaxi, which Waymo cooperates with Krypton?

As a leader in the field of autonomous driving, Waymo has also tried to build his own car.

In May 2014, the autonomous driving team released a code-named ""fireflyThe unmanned car is planned to invest 100 vehicles in a small-scale trial operation in California in the early stage.

Due to the imperfection of the supply chain, the cost of Firefly is high, and the original 100 cars were finally cut down.50 vehiclesCar, coupled with the slow progress of the project, Google finally gave up its own car-making route.

In 2017, Google announced the retirement of Firefly.

In 2018, Waymo made an ambitious announcement to purchase from Land Rover and Fiat respectively. 20,000 vehiclesI-PACE and62,000 vehiclesDajielong is used to build a self-driving fleet.

In order to expand the operation scale of the fleet, in 2019, Waymo announced the establishment of the world’s first factory to produce L4 self-driving cars in Michigan, USA, which is mainly responsible for modifying the purchased existing production cars.

Up to now, there is no sign that Waymo has achieved his goal.

According to public data, Waymo’s current fleet size is only over 1,000 vehicles, and the current practice is still to install automatic driving kits on production vehicles.

This seems to be efficient, but it will bring many problems.

The first is the vehicle.Basic quality. The existing control system of mass production vehicles is built on the basis of human drivers, and the basic functions, including throttle, braking and steering, are all completed by traditional mechanical transmission, but this is completely different operation logic for the automatic driving system that relies on electronic signals to control vehicles.

Followed by the vehicle.Functional scene. Self-driving cars are essentially liberating drivers. Starting from the needs of passengers, we define what kind of functional scenes a self-driving car should achieve. However, most existing production cars are just a family car with comprehensive functions, and the layout of the cockpit cannot be changed, which cannot further expand the practicability of the vehicle.

Finally, the vehicle’scost. The needs of C-end users and B-end users are different. To build a self-driving car and a family car, the investment of BOM cost is completely different.

When refitting on the existing vehicle platform, it is necessary to bear all the BOM costs of the original private car, and it is also necessary to superimpose the cost of the autopilot kit, which is a great challenge to reduce the cost, which also leads to the large-scale investment of the refitted car and the cost of bicycles.

From the perspective of scale, Waymo urgently needs a mass-produced Robotaxi model.

In the negotiation with Krypton, Waymo once put forward requirements for vehicles-comfort comparable to S-class, chassis control comparable to e-tron, vehicle energy consumption comparable, and required the service life of operating trucks.

On the one hand, due to Waymo’s strong dominance, car companies can only play the role of engineering development and vehicle manufacturing.

On the other hand, based on Waymo’s personalized requirements for vehicles, car companies are reluctant to develop an exclusive self-driving car platform from scratch. After all, the current commercial feasibility is far lower than the research and development cost.

This is why Waymo’s previous cooperation model with car companies is relatively simple.

Waymo only purchases complete vehicles from Fiat Chrysler, Jaguar Land Rover and-,and deploys the sensor kits needed for autonomous driving on these vehicles through modification, and then carries out the real road test of autonomous driving or the self-driving taxi test.

Looking at the world, there are very few companies that can enable autonomous driving companies like Waymo to achieve mass production based on the vast -M architecture.

To put it another way, whether an autonomous driving company wants to build a car depends largely on whether it can find a useful carrier.

Based on this kind of thinking, a route that can not only be developed from zero to positive, but also hand over the burden of building cars to partners has become a new choice for autonomous driving companies such as Waymo.

The first is inProduct experienceOn the level, different from the traditional car model focusing on the driver’s thinking, the mobile travel vehicle built by the vast -M architecture is oriented to the automatic driving application scene, and the biggest highlight is reflected in the "user" experience:

The wheelbase of the vast -M architecture itself covers 2700mm-3300mm, and such a wide range of wheelbase makes the model extremely scalable-the front and rear suspension of the vehicle can be adjusted, and the distance between the seat and the rear axle can be stretched, finally providing a flexible layout of the cockpit space.

The second iscost. For self-driving cars, cost has always been the most sensitive issue.

A modified model with an automatic driving system, the price is500-1 millionRenminbi. In this cooperation with Krypton, Waymo’s demand is "to get the best things with the least money".

Yang Dacheng said, "Based on the efficient universality and scale of the vast architecture itself, the vast -M architecture can meet the needs of users with different budgets. 」

The third isquality. M-Vision meets the global five-star safety standards and conforms to the American Highway Safety Insurance Association.(IIHS)Maximum safety requirements. M-Vision can guarantee 500,000 kilometers in five years and meet the requirement of 16 hours of uninterrupted operation every day.

As early as the launch of the vast architecture, Geely said that the vast architecture will launch products with full open road autopilot function in 2025.

The debut of M-Vision also marks the further verification of the intelligent planning of the vast architecture.

03、Extreme krypton press the "fast forward key"

Waymo provides autonomous driving technology, and Krypton provides highly customized exclusive vehicles-this cooperation mode provides a new problem-solving idea for the landing of autonomous driving.

In addition to Waymo, other autonomous driving companies can also realize the landing of autonomous driving products based on the vast -M architecture.

As the most important smart electric vehicle brand under Geely Holding, through the commercial cooperation with Waymo, the vast -M architecture can also be fed back to the passenger car market in the future, thus enhancing the competitiveness of the brand.

Not long ago, Yang Xueliang, vice president of Geely, revealed on the social platform:

"M-Vision is a customized Robotaxi for Waymo in the United States, and M-Vision also has plans to promote To C products. 」

It is understood that the vast -M architecture will retain two versions of steering wheel, pedal/steering wheel and pedal at the same time.

According to informed sources, there are currently two products under development in the vast -M architecture:

With the continuous growth of the launch and delivery of the second new car 009, the product matrix of Krypton is accelerating.

According to the previous plan, Krypton will cover cars, SUVs and sub-categories around three product lines: Z, C and M in the next two years:

At the same time, Krypton will enter the global market, and Krypton 001 will enter the European market in 2023.

At the beginning of its development, Krypton fully considered the European standard and American standard, and certainly did not rule out a larger scale in the future. Extreme CEO An Conghui said.

Behind the market opportunity game, production capacity is the key to break through.

"Krypton currently has a production capacity of 300,000 vehicles, so it is no problem to ensure production and delivery, because we have other factories. In recent years, the new factories have also comprehensively considered the production needs of electric vehicles, and can realize the manufacturing of vast architecture products in the fastest time. At the press conference of Krypton 009 in November this year, An Conghui said.

Up to now, Extreme Krypton 001 has become the sales champion of China brand 300,000 luxury pure electric vehicles for three consecutive months-a total of 60,000 vehicles have been delivered, and the average order amount has exceeded.336 thousand.

Through the performance of krypton sales, An Conghui’s "internal letter" to internal employees shows that:

"The success of a single product cannot bring about the sustainable development of a brand. The diverse needs of users require us to complete the product layout from single product explosion to multi-product development as soon as possible. 」

Different from the cooperation mode of the new forces in the head and the internal incubation mode of traditional car companies, it relies on Geely+Volvo’s car-making experience and technical resources, but from decision-making to the accumulation of marketing experience, it has gone through a complete process from 0 to 1.

In other words, Krypton is exploring a route that combines the technical background of traditional car companies with the flexibility and efficiency of new cars.

As you can see, based on "Geely+Volvo technical resources are the underlying logic.",as well as the self-evolution of users’ travel needs, it is accelerating to prove the feasibility of building a third track.

The new owner of BYD Qin plus dmi: Share the 7 advantages and 7 disadvantages summarized by the individual.

Advantages: 1. There are two braking modes, standard and comfortable, corresponding to different crowds, and the comfortable braking distance is long. The measurement of 42 meters of that brake is estimated to be braked in the comfortable mode, and the standard 30 meters is the most. 2. Very fuel-efficient. After all, dmi’s mysterious technology is full of meters with a battery life of 1,200 kilometers. In my case, there are still 900-1,000 kilometers. After calculating, my old car will save at least 500 yuan a month. Some people like to say that dmi’s technology is more expensive, but as a car of hundreds of thousands, what’s the point of your demanding so much?

3. The power is smooth, and the throttle opening and power matching are very accurate. Those who say that they will be frustrated are either the central control setting energy recovery to the maximum, or the accelerator pedal is slammed, or the car is evaluated by the cloud. 4. The dynamic response is very timely, especially at middle and low speeds. This car is actually a commuter artifact. If the acceleration is slower than 100, the fuel consumption and power consumption will rise sharply, but for me, the high speed is 80-100, which is completely enough. 5. There’s a lot of space. I’m 183. I’m sitting in the driver’s seat and I have two fists from the roof. The seat is well adjusted and there is no shortage of space. 6. The reversing image is clear, automatic parking is very practical, and the safety of blind spot detection in rearview mirror is good. 7. The app is very easy to use. In the underground parking garage, the air conditioner can be turned on remotely, and the signal reception is a bit powerful. The 4G card in the central control is free for the first year, and then it seems to be 3-400 years.

Disadvantages: 1. The interior is not exquisite enough, and some places are full of plastic, which is at the same level and quite different from the interior materials of Han. 2. The tire noise is a bit loud, mainly because the engine sound is gone, and the tire sound is particularly obvious. I wonder if it will be better to change the silent tire. But this is after 30,000 kilometers, so we don’t consider changing tires for the time being. 3. When the vehicle starts, it will make a harsh rubbing sound, such as the parking device is not released and rubs against the brake pads. I feel that it is a case. I plan to let the maintenance master do a whole car inspection when I first insure it to see if the brake pads are not properly adjusted. 4. Buying a car is the original price, and there is no discount at all. I can’t even tell the service of the manufacturer clearly, and I didn’t ask for a gift. I booked it on March 4, and waited for 3 months, but I didn’t send a dragon film or a driving recorder.

5. The dashboard is really small and ugly. It is recommended to choose the racing instrument when you buy it, because the racing instrument can be embedded for free, and vice versa. 6. APP sometimes reports errors. Previously, the tire pressure information of the left front tire was not visible, but it can be seen by tire pressure monitoring when you get on the bus. Doubt is a functional problem of the APP. 7. There is a big problem in the back row of space, and the chassis is still not high enough from the ground. After all, the chassis is hung with batteries, so it is very embarrassing to scrape it. To sum up: this car consumes oil, but it takes the circuit. The power has little to do with the engine, but it is related to the output capacity of the power motor. The power battery should provide the power difference between the peak power of the motor and the engine power, leaving a margin of about 30-50kw. If this car is not charged, buying 55 is the best solution. If 120 is matched, pay attention to the installation of electric piles. The distance from the electric meter is 15 meters, and it says 30 meters, but it has to be counted back and forth.

Junior year married, senior year students, undergraduate students take baby to shoot graduation photo into online celebrity.

  Near the graduation season, a group of photos of "National People’s Congress graduates bring their babies to take photos of undergraduate graduation photo" set off a circle of friends. Compared with the combination of handsome men and beautiful women, the children under 2 years old in the photo obviously attracted more attention.

  Parent-child graduation photo Huobao Network

  Recently, Mao Yanzheng, a photographer who once became popular for shooting "Goddess of the National People’s Congress", posted a group of photos of this year’s graduates through his personal WeChat WeChat official account. Once the photos were sent out, they quickly attracted a lot of attention and forwarding. It’s just that this time it’s not a beautiful graduate who attracts everyone’s attention, but a young couple of undergraduate graduates.

  Photographer Mao Yanzheng said: "On campus, I have seen people wearing doctoral uniforms and occasionally met people wearing master’s uniforms, but this is the first time I have seen a child wearing a bachelor’s uniform to take pictures with his parents, and his parents are also wearing bachelor’s uniforms."

  In the photo, the young couple, like many campus couples, chose to record their graduation time in front of the school gate, playground, Wu Yuzhang sculpture and other representative buildings. What is different is that they have a "little model" around them, their son who is over one year old.

  Graduates of the same age threw up their graduation caps at the school gate to celebrate. The undergraduate couple have already thrown up their babies. Therefore, the couple are called "winners in life" by many friends. Some people envy their loving feelings and marvel at the speed of their lives. Of course, some people question whether it is appropriate to be a parent so young.

  According to a teacher of the National People’s Congress, the school has no special regulations for students to get married and have children. In previous years, master students and doctoral students took photos of graduation photo with their children from time to time, while those wearing bachelor’s uniforms took photos of their parents.

  Start a business while raising children

  Liao Siqi, a girl in the photo, is a 2012 student in the School of Journalism of Renmin University of China. She went to Columbia University for an exchange for half a year.

  According to the memories of their college friends, their love began in their sophomore year. "Not many students can achieve positive results during their undergraduate years. To be honest, they can see that they are doing well, which is a little unexpected, but reasonable, and the rest are blessings."

  When everyone’s impression of Liao Siqi still stays as the host of the 75th anniversary celebration party of Renmin University, she has upgraded her role and become a young mother.

  She shared on her WeChat WeChat official account: "Before he was born, I looked forward to the baby’s birth every day. But when I heard the baby’s first cry, an unprecedented pressure forced me to raise a new life. "

  Fortunately, unlike the TV series in which young parents are always dazzled by their children, the young post-90s couple soon found their own parenting methods. Make it cool and easy to take care of the baby. "Without the guidance of nurses, I downloaded a lot of maternal and child apps with my father, bought a lot of books to take care of children, paid attention to many maternal and child websites, and even searched various papers at home and abroad in the academic database." The child’s father said: "Without the guidance of the previous generation, we were like a blank sheet of paper at first, which made us willing to try and summarize all kinds of new knowledge and methods of parenting." A little practice and research made the young parents adapt to the new role quickly.

  In May of this year, they started their entrepreneurial career together when they were about to graduate. They hoped to pass on their special parenting experience and ideas, and new products would be launched later. Liao Siqi said: "I became a mother when I was very young. Although many people think that having children will be a burden in my life, in my heart, having a son is my most correct and happiest decision. At this age, there are the most youthful and beautiful us and the cutest little baby. My child’s father and I are not only accompanying but also growing up with him. "

  Parenting is an adventure, and she hopes to help more babies and parents with her parenting experience, "in this wonderful life journey, the harvest is happy and complete."

  The same university, different choices

  As an old friend, Lu Xingji from the School of Journalism of the National People’s Congress told the Beijing Youth Daily reporter: "When I learned that they had a baby during their undergraduate years, my first reaction was ‘ Not reliable ’ 。” But after witnessing with his own eyes how the young couple took care of their children over one year old without the help of their family elders, Lu Xingji said that he was really impressed by their experience. "I found that once I get started with this big event, people will become super reliable, which makes me realize that actually falling in love and getting married is a very important lesson for people at this stage of college, and it is also a kind of progress in life."

  Teacher Sun Jiazhou from the School of History of Renmin University also forwarded this group of graduation photo on social media. He said in his comments: "In ‘ Seeking truth from facts ’ I have seen a lot of photos taken in front of the school motto stone, but this photo shows the cheerful charm of life, which is unforgettable! "

  Of course, some students expressed different opinions. Several students said that although they wished the young parents well, they did not envy them. A student who is studying for a postgraduate degree told the reporter of Beiqing Daily that there are still many practical factors to consider when getting married early, but he obviously does not have it.

Test drive | The new Volvo XC60T8: 5.5 seconds to break a hundred, the safest car is also a performance beast?

I just finished the test drive of the new Audi Q5L (parameter picture) in Nan ‘ao Island, and then I met the new Volvo XC60 in Chengdu, which undoubtedly made me have a more concrete comparison and understanding of these two luxury medium-sized SUVs with similar positioning but different styles.

The changes of the new Audi Q5L are not detailed here, and interested friends can jump to this content.

Today, I’m going to talk about the new Volvo XC60, which just came into the market in early June. The price of the new car is 373,900-603,900 yuan.

As a mid-term redesigned model, in terms of appearance, the new XC60 is equipped with a sports version for each version, including the T8 version; Secondly, the whole system is equipped with a hybrid system; Of course, there is also the native Android car system and the construction of software ecology, which makes this car better meet the growing scientific and technological needs of current users.

During the test drive, we drove a T8 version of the car, which is the official price of 603,900 yuan, with 5.5 seconds to break the hundred, and the top version of Baohua Weijian 15 speakers and air suspension. Although this version is not the main sales version, but looking at the attractive configuration list, what is the experience of these top luxury collocations? Let’s explore together.

The transition from "t" to "b"

Friends who are familiar with Volvo must be very familiar with the numbers T4, T5 and T8, because these characters represent the composition of power. For example, T4 is the ordinary version of the 2.0T engine, T5 is the high-power version of the 2.0T engine, and T8 is the plug-in version.

On the new XC60, you will notice that the former "T4 and T5" have become "B4 and B5", and the change from "T" to "B" actually means that the XC60 has officially opened the "mixed era".

Among them, B4 and B5 models adopt the power combination of 2.0T+8AT and are equipped with a 48V hybrid system. The B4 model, which focuses on energy saving, has a comprehensive maximum power of 145kW, an acceleration of 8.4 seconds per 100 km, and a comprehensive fuel consumption of only 7.0L per 100 km. The B5 model has a maximum output power of 184kW and a maximum torque of 350Nm, with an acceleration of only 7.1 seconds per 100 km and a comprehensive fuel consumption of 7.3L per 100 km.

With the addition of 48V hybrid system, the effect is still very obvious. Firstly, the energy consumption is reduced, and secondly, it can provide additional power supplement in the initial stage, so that the start is smoother and the control of start and stop is smoother, which provides a very good supplement for the luxurious driving feel.

The T8 version of our test drive, that is, the plug-in hybrid vehicle, is equipped with a 2.0T high-power dual-supercharged engine and the power configuration of the rear axle motor. The comprehensive maximum power of the system is 288kW(391 HP) and the maximum torque is 640 N m. At the same time, the new car has a battery pack of 11.6kWh and a pure electric cruising range of 50km, which means that the new car can be directly on the green card.

In the road experience, the biggest surprise of this set of power is "full explosion". The output of 391 horsepower can make the people in the car feel the pleasure of being backed up by the seat in 5.5 seconds. In terms of NVH quietness, it is also extremely quiet. Even if the battery is exhausted, it can be extremely quiet and full of advanced feeling.

While improving the power, the new XC60 adopts a brand-new sixth-generation Borgwarner four-wheel drive system, which can automatically judge the road conditions, reasonably distribute the power between the wheels, and control various road conditions and weather. At the same time, it is also equipped with an electronically controlled braking system, and the braking response speed of 0.15 seconds is twice as fast as before.

In terms of braking, the adjustment of the new XC60 can be said to be very heel-following. Even if kinetic energy recovery is started, there will be no particularly big drag on the whole, which can give drivers a reassuring braking performance. It is worth mentioning that the new car can "reduce the steering power" alone, which makes the steering wheel feel heavy and enhance the sense of movement.

Technological upgrading is surprising.

If BBA emphasizes some luxury attributes, such as Audi’s technological luxury and BMW’s sports luxury, then Volvo is practical luxury. This point is particularly obvious in the technological upgrade of this change.

Volvo finally figured it out. Instead of spending huge sums of money to build a car machine system to compete with hundreds of mobile phone stands, it is better to study why users don’t like to use the current car machine.

The native Google Android operating system is the best proof. Instead of taking the time to learn the car system, it is better to "carry" the familiar mobile phone system directly to the car in one step to achieve seamless connection.

And the system has built-in very rich application functions, such as car version of Gaode map, Tencent love listening (including QQ music, Himalayan, etc.). In addition, there are Tmall Elf, Huawei Smart Assistant and Huawei Application Market which can be interconnected with smart homes, and more applications can be expanded.

In the actual experience, you will find that our favorite voice control only needs a sentence "Hello, Xiaowo!" " The new XC60 can also respond intelligently.

And this voice control supports continuous dialogue, that is to say, turning on the air conditioner, checking the weather, asking for navigation, and playing music can all realize continuous operation after one wake-up. Although this is not a black technology, it is already a very big breakthrough for a luxury car that is slow in technology.

As for safety, this has always been Volvo’s label, so the new XC60 performs equally well in active/passive safety configuration!

The whole system comes standard with a new generation of CitySafety urban intelligent safety system. With the blessing of 20 hypersensitive sensors, the new car has practical functions such as preparing to leave the car, automatic braking backwards and emergency parking assistance, and active hedging intervention all the time. It can be said that in terms of safety, there is no most comprehensive, only more comprehensive.

Let’s talk about the luxury used.

After the test drive of the new Volvo XC60, I launched a survey in the circle of friends-how many people like Volvo because of the crystal gear?

As a result, I got a very positive response from my friends. In fact, everyone is very concerned about these inconspicuous details on luxury cars, because this is also the best way to distinguish Volvo from other brands, a difference in style.

Scandinavian style originated from northern Europe, its core is to pay attention to practical functions, exercise restraint in form and decoration, and use natural materials as much as possible, thus creating a harmonious aesthetic feeling.

The luxury version of the new XC60 comes standard with a crystal gear lever that was previously only available for T8 plug-in hybrids. It is made of crystal and metal, and its shape is elegant and delicate. The "orreforssweden" on it means that it is produced by the Swedish century-old crystal brand orrefors, and its "Black grouse" logo has become one of the most famous trademarks in the world today.

In addition, the material of the decorative board also caught my attention. I thought it was a solid wood decorative board, but it didn’t feel like it. Finally, I learned that it was a special "drifting wood" material. Applying this kind of material, which has always existed in nature but is not common, to the interior design of vehicles really makes people feel close to nature.

Besides, Baohua Weijian Bowers&Wilkins audio system, a hall-level audio system tailored for XC60 cockpit, not only has 15 speakers and a maximum power of 1100W, but also uses DiracHDSound? audio fidelity technology to support FLAC and WAV lossless formats.

When the music sounds, it’s like being in the Gothenburg Concert Hall. Of course, this standard is the top model, and the regular model is equipped with Harman Kardon audio, but it is optional, and the optional price is 25,800 yuan.

And the most practical air suspension. Not only does it improve the comfort of the whole vehicle, but in the scene of opening the trunk to place items, this air suspension system can also lower the buttons through the rear axle of the car body in the luggage compartment, so that the height of the rear of the car can be lowered by 50mm, which is more convenient for the loading and unloading of large luggage. The details reflect Volvo’s humanistic thinking everywhere.

Hong ping Dian che

I have to say that Volvo can always surprise people!

After all, from the modeling point of view, XC60 gives people the feeling of being steady and extremely low-key, but when you really walk into this car, understand and control this car, you will find that this car not only has top safety technology, but also is obsessed with providing top safety.

You will also find that the Nordic design, extreme performance, low-key luxury, etc., in fact, XC60 has also done a good job, including the polishing of luxury details, and there are also surprises, so people can’t help but follow the script, which also makes Volvo’s unique charm.

"courage" and "confidence" of Geely xingrui

    International Online auto channel News: The leading position of the joint venture brand in the domestic A-class car market has already taken shape. No matter the product differentiation in the market segments or the absolute fighting power of the fist products, the self-owned brand A-class car products have to rely on low-price routes to exchange for the market, and the original "price lever" is used to incite consumers’ enthusiasm.

"courage" and "confidence" of Geely xingrui

Geely xingrui

    When Geely Xingrui entered the A-class car market with the official guide price of "Gundam" of 113,700-149,700 yuan, it was hard not to admire the "courage" of this brand-new model to compete with the joint venture brand for price balance, and behind this "courage" was the concern and expectation for the product strength of the market challenger.

    CMA platform technology "full coverage"

    As Geely’s first A-class car based on CMA platform, the platform’s highly flexible "bandwidth" advantage breaks the inertia rules and design restrictions of A-class cars. Xingrui has a wheelbase of 2800mm, a body width of 1869mm and the widest wheel track of 1618mm, all of which are absolutely leading levels for A-class cars. As a pioneering work in the era of "Geely 4.0", Xingrui outlines a dynamic "wide-body" style through the extension and widening of lines and curved surfaces, and the A-class car users who have high demands on product space and size will definitely have a very good first impression on Xingrui.

CMA platform

    The technical advantages of CMA platform in electronic and electrical architecture also give the A-class car Xingrui excellent intelligent technology experience. Star Rui comes standard with the OTA cloud upgrade system of the whole vehicle, which fully meets the sustainable expansion of application ecological functions such as information interconnection, autonomous driving and big data cloud service, so that it can be upgraded instantly and remotely like computers and mobile phone systems, and comprehensively improve the digital intelligent driving function of automobiles. The 540 transparent chassis, 7.5-inch full-color HUD head-up display, APA automatic parking system and RPA mobile phone remote parking that can be pushed through OTA cloud are equipped with Xingrui. Compared with the impression that the A-class car configuration is lackluster, it undoubtedly realizes the leapfrog product experience.

Geely xingrui interior

    At the same time, Xingrui follows the concept of Geely’s "all-round healthy car", adopts NAPPA leather antibacterial steering wheel and VOC grade eco-friendly antibacterial materials, and is equipped with a G-clean air purification system integrating CN95 high-efficiency composite air conditioning filter element, AQS intelligent air quality management system and negative ion air purifier, realizing ecological safety protection functions such as eliminating pollution from the source, intelligently blocking pollution, positive pressure defense inside the car, internal and external monitoring of air quality and high-efficiency air purification. When experiencing the visible product advantages, "invisibly" sets the standard of healthy cars for users and builds an intelligent ecological health circle covering the whole life cycle of products.

    Power advantage says no to "enough is good"

    The mainstream products in the A-class car market are mainly small-displacement turbocharged engines, and 1.4T/1.5T/1.6T turbocharged engines are popular. Although the engine parameters are squeezed, the engine displacement and product positioning limit the power line, and "enough is good" has gradually become the established standard of A-class car products.

"courage" and "confidence" of Geely xingrui

    Geely Xingrui’s 2.0TD in-cylinder direct injection turbocharged engine is undoubtedly a "heterogeneous" product of the same class, and the parameters of maximum output power of 140kW/4700rpm and peak torque of 300Nm/1400-4000rpm are not much better than those of B-class cars. At the same time, the compression ratio of this 2.0TD engine is as high as 11.3, and it matches the 7-speed wet powershift. The shift time is only 0.2 seconds, and the maximum transmission efficiency is as high as 97%, which can effectively reduce the fuel consumption and achieve a comprehensive fuel consumption of only 6.7L/100km. Compared with competing products, Xingrui has a large displacement but also achieved a balance in power performance and fuel economy.

"courage" and "confidence" of Geely xingrui

Geely xingrui active security

    What is even more surprising is that Xingrui has a front-to-rear weight ratio close to 50:50. With the "drive-by-wire chassis", E-type multi-link independent rear frame, ITT brake pads and long-stroke shock absorber design, it has strong grip and excellent cornering controllability, taking into account driving comfort and sports driving controllability. At the same time, a highly perfect intelligent safety system has been built in terms of active and passive safety, which integrates the L2-level autopilot technology with ICC intelligent navigation system, FCW pre-collision warning system, AEB-P pedestrian identification system, BSD blind zone monitoring system, SLIF speed limit information reminder function, ACC S&G start-stop adaptive cruise system and other functions. It also comes standard with Bosch 9.3 ESC body electronic stability control, BA brake assist, HAC uphill assist, Auto Hold automatic parking +EPB electronic parking, tire pressure monitoring system, automatic locking of driving, front and rear parking radar and other rich safety configurations, ensuring the safety of driving and traveling in all dimensions.

    Write at the end:

    What kind of feedback Geely Xingrui will get when it enters the market at the price of joint venture competing products? We might as well make a bold prediction from another field. In 2020, the Double Eleven Shopping Festival came on November 1st ahead of schedule, which is also the day when Xingrui went public. On the first day of the Double Eleven market opening, Nike, the "one-size-fits-all" in the basketball shoe field, made considerable efforts to sell its own star signature shoes at a discount, and the basketball shoe product line under Adidas plunged in collective prices except for a very small number of star shoes. Obviously, when the product competitiveness is excellent enough, consumers are willing to pay for its excellent product strength even if the price is firm, and the brand awareness in inertia thinking is not as unbreakable as imagined. Whether Geely Xingrui’s "confidence" can hold up his "courage" only depends on the market sales data. (Author: Huang Yi)

Lei Jun responded to why Xiaomi built a car quickly.

Elephant journalist Chen Zhengyi

On April 6th, Tamia Liu Weibo, CEO of Zhiji Automobile, issued a document praising Xiaomi Automobile for its high efficiency and high speed, but wondered how it was achieved.

Previously, Xiaomi CEO Lei Jun had already answered in the video, "It takes only three years for Xiaomi to build a car. Why is it so fast?" The problem.

Lei Jun said that Xiaomi has 14 years of experience and accumulation, and has formed a very reliable R&D team. Now there are about three or four thousand engineers.

High-value and high-product-force vehicles have emerged. Chongqing’s automobile industry has changed from "quantitative change" to "qualitative change"

On December 26th, AITO authorized the user center, and many consumers came to consult and learn about AITO’s M9.

This group of pictures was taken by reporter Zhang Jinhui/Visual Chongqing

On December 26th, the flagship SUV AITO, a panoramic wisdom cooperation between Cyrus and Huawei, was officially released. This car is not only the epitome of the most advanced technology and the latest manufacturing technology in the automobile industry, but also enhances the perception of the "Made in Chongqing" car.

A few days ago, the National Bureau of Statistics also released the latest data. From January to November this year, Chongqing’s automobile production reached 2,074,200, up 10% year-on-year, ranking second in the country.

Over the past decade or so, the ranking of Chongqing’s automobile production in the country has fluctuated. Now Chongqing ranks among the top in the country again. The industry is more concerned about the specific path to promote the development of local industries. After all, it is difficult to sustain the current automobile industry structure through the "impulse" of low-end products.

Chongqing’s auto industry has performed brilliantly this year. Is there really a "new power" blessing behind it? From the emergence of AITO M9 and the performance of major auto companies in Chongqing this year, we can see that Chongqing’s auto industry is changing from "quantitative change" to "qualitative change".

The price of high-end cars rushed to five or six hundred thousand yuan.

Since the second half of this year, the AITO series products jointly designed by Cyrus Auto and Huawei have continued to sell well. In November, the sales volume of Sailisi new energy vehicles reached 23,834, up 104.39% year-on-year; Among them, the sales volume of Sailis brand was 20,318 vehicles, up by 145.92% year-on-year, both hitting new highs.

Changan Automobile is still strong. In November, the sales volume of its own brand new energy vehicles exceeded 50,000, a year-on-year increase of 52.73%.

The reporter learned from the Municipal Economic and Information Committee that the output of new energy vehicles in Chongqing in November increased by more than 100% year-on-year, which also far exceeded the year-on-year growth rate of total local automobile production in the same period.

The relevant person in charge of the Municipal Economic and Information Committee said that since 2023, the contribution rate of new energy vehicles in Chongqing to the growth of the city’s automobile industry has reached 85%.

"Behind the recent bright performance of Chongqing Automobile, it is obviously driven by high-end models, especially high-end intelligent networked new energy vehicles." A related person from Chongqing Automobile Business Association said that a large number of "Made in Chongqing" vehicles with high value and high product strength have emerged in this year, with intensity and frequency exceeding any previous period.

The reporter combed the "Made in Chongqing" new energy hot-selling models launched this year, and found that most of them are mid-to-high-end vehicles, such as the dark blue S7 model of Changan, whose price is between 150,000 and 220,000 yuan, while the price of Aouita 11 HarmonyOS Edition and Aouita 12 is between 300,000 and 400,000 yuan. The price of Sailis AITO’s M5 Smart Driving Edition and AITO’s new M7 covers 250,000 to 400,000 yuan. AITO asked M9 to push the price above 500,000 to 600,000 yuan.

The new path makes "Made in Chongqing" cars sought after.

In the eyes of the industry, the above changes in Chongqing’s automobile industry follow a profound value logic.

On December 16th, in the special activity of Chongqing International Talent Exchange Conference, Li Keqiang, an academician of China Academy of Engineering and chief scientist of Chongqing Western Science City Intelligent Networked Automobile Innovation Center, pointed out that the automobile industry will usher in the 4.0 era, and the new generation of automobiles will reflect the characteristics of low-carbon energy, electrification of power, intelligent body and networking of transportation networks, and the original automobile development mode, production mode and ecology will change.

Dong Yang, vice chairman of China Electric Vehicle committee of 100, believes that people’s "quality view" of automobiles has changed, from focusing on quality to focusing on experience. "In the past, when a new car was released and 20 new technologies were listed, it was amazing that users could use one or two items. Each car also brought a thick manual, and no one read it. This is no good. Car companies must directly face users, find out what needs users have, and let users make full use of new technologies. "

"First, we must’ change’ and strive to develop new technologies in the direction of intelligent networking and new energy; The second is to be’ close’, close to the needs of users, shorten the distance with users and reduce communication costs. " The relevant person in charge of Changan Automobile said.

A closer look at the many products newly launched by Chongqing car companies such as Chang ‘an and Sailis this year shows that they all follow the above ideas.

Taking the M9 as an example, by adopting the innovative owl-enhanced steering technology, the turning radius of a 5.2-meter-long "big guy" is smaller than that of a medium-sized car. In addition, the model also has 2.6 million pixels of fine lighting with dual lights. When the high beam illuminates the opposite vehicle, it will automatically leave a dark area, which will not affect the opposite vehicle, but also keep the high beam.

Qu Yunchao, a market observer, believes that some of the above technologies and functions have solved the pain points of users, while others have opened up interesting or comfortable new experiences for users. Since the beginning of this year, the popularity of "Made in Chongqing" cars has proved the success of this path.

It takes "one step at a time" to become a world-class company.

In the new year, how can Chongqing’s automobile industry anchor new development coordinates? "The global automobile industry pattern is undergoing subversive changes." Zhu Huarong, Chairman of Changan Automobile, said that from Europe, America, Japan, Germany and South Korea, where China was divided into six parts, to China, where the brand occupies half of the country today, the advantages of China brand in modeling, new energy and intelligence lead the world, and its scale advantage is further highlighted, and its competitive advantage in changing lanes is even more obvious.

But it also brings a series of new problems-

For example, the future development of China’s automobile industry will no longer be promoted by learning from the outside world. Another example is that the boundary of the division of labor between the whole vehicle and parts is reconstructed, and the battery of new energy vehicles is rapidly transformed from shortage to overcapacity.

To solve these problems well, we can move towards the first-class in the world, and the road is only "one step at a time". Zhu Huarong believes that it is necessary to take five steps to meet the challenges in the critical period of track switching in the industry by accelerating the layout of products and production capacity, strengthening the layout of brand building, strengthening the layout of marketing services, accelerating the improvement of market layout and strengthening the layout of organizational talents.

Zhang Xinghai, the chairman (founder) of Sailis Automobile, said that the local area is currently in the best opportunity to develop new energy intelligent networked vehicles. A strong supply chain can support a strong vehicle enterprise, and the industry should further expand open cooperation and let professionals do professional things to create high-quality products that meet the needs of users.

Relevant persons of the Municipal Economic and Information Committee said that Chongqing will strive to basically form a new ecology of intelligent networked new energy automobile industry by 2025, and build a world-class intelligent networked new energy automobile industry cluster by 2030, with the industrial scale reaching the world-class level.

To this end, Chongqing will continue to expand its industrial scale, accelerate the completion and commissioning of new projects, put new products on the market, and develop new brands, and strive to build a trillion-level intelligent networked new energy automobile industrial cluster; Adhere to the whole zero coordination, implement major projects to attract investment, cultivate and upgrade key enterprises, transform and upgrade traditional enterprises, and promote intelligent networked new energy vehicles to supplement the chain and strengthen the chain extension; Strengthen the integrated layout of charging, storage and parking, vehicle and Lu Yun infrastructure, promote the integration of energy network, transportation network and information network, and strive to form a moderately advanced, rational, intelligent and efficient charging and replacing service system; Accelerate the network transformation of existing roads and create the most distinctive and rich vehicle-road collaborative experience scene in China.

The first "Made in Chongqing" panoramic wisdom flagship SUV

AITO asks M9 to go public.

On December 26th, at the press conference of the M9 and Huawei’s whole winter scene, the first "Made in Chongqing" panoramic wisdom flagship SUV AITO was officially launched, and four models were launched in two power versions, namely extended range and pure electric, with a price of 469,800-569,800 yuan.

AITO Jiejie M9 was jointly launched by Chongqing car companies Cyrus and Huawei, and adopted a brand-new family design "Kunpeng Wings Spreading". The new car applied a number of cutting-edge innovative technologies, such as "Super Xuanwu Body", which was the world’s largest one-piece die-casting, and the lightweight coefficient was significantly higher than that of the same class. The 12 parts of the whole car also adopted 2000 MPa nuclear submarine-class hot car steel.

Huawei Turing Intelligent Chassis, equipped with AITO Wenjie M9, comes standard with intelligent closed air spring and CDC variable damping shock absorber, supports 5-speed body height adjustment, and also has a full-scene smart road preview system with adaptive active suspension, which can smoothly cope with different road conditions.

In terms of power, AITO’s M9 extended range version is equipped with a drive system consisting of a 1.5T engine and front and rear motors, with an acceleration of 4.9 seconds at zero and 4.3 seconds at zero for the pure electric version. The fuel consumption of the extended range version is as low as 6.9 liters per 100 kilometers, the comprehensive battery life is as high as 1402 kilometers, and the pure battery life is as high as 275 kilometers. The pure electric version is equipped with Huawei’s "Whale" 800-volt high-voltage battery platform, which can achieve a battery life of 150 kilometers in 5 minutes and an overall battery life of 630 kilometers.

In terms of automatic driving, M9 adopts Huawei ADS2.0 advanced intelligent driving, equipped with industry-leading 192-line laser radar, and cooperates with high-definition camera and millimeter-wave radar to support intelligent driving of national highways, urban expressways and urban areas.

AITO M9 is expected to be delivered in batches on February 26th next year. The relevant person in charge of Cyrus said that the company has built a world-leading super smart factory in Chongqing, with intelligent manufacturing equipment that integrates advanced technologies such as AR vision and big data. The key processes are 100% automated, and a new car can be rolled off the assembly line every 30 seconds, with the highest production efficiency in the world.

The style of the front face was adjusted, and the 2024 Geely Xingyue L Hi·F was unveiled and replaced with a 1.5T four-cylinder engine.

A few days ago, Geely Automobile’s 2024 Xingyue L Raytheon Hi·F hybrid version was officially unveiled. Although it was only an annual change, the appearance of the new car was greatly adjusted, and the body size was also improved. It was also replaced with a new 1.5T four-cylinder engine. For reference, the price range of the hybrid version of Xingyue L Raytheon Hi·F oil and electricity currently on sale is 171,700-183,700 yuan.

In terms of appearance, the front face of the 2024 Xingyue L Raytheon Hi·F petrol-electric hybrid version continues to use the straight waterfall air intake grille, and the interior is filled with several vertical chrome trim strips, but it has changed from the concave design of the current model to the outward protruding style, which is also Geely’s latest family style and looks fuller. In addition, the silver Geely LOGO also helps to enhance the sense of grade.

The interior of the headlight groups on both sides continues to ensure the eye-catching effect after lighting through the upper and lower groups of three-stage daytime running lights. The front enclosure has been redesigned, and the L-shaped blackened decorative board is added in the decoration of the vertical diversion groove, which forms a penetrating style with the lower grille, which helps to enhance the fighting atmosphere.

The shape of the side of the car body has not changed much, and a more square and atmospheric visual effect is created through straight lines, which is in line with the aesthetics of most consumers. It is worth mentioning that the D-pillar position is also inlaid with the "Tiangong" nameplate, which looks quite chic. In terms of body size, the length, width and height of the new car are 4795/1895/1689mm and the wheelbase is 2845mm, which is 25mm longer than the current model.

The design of the tail is the same as that of the current model, and it is equipped with penetrating taillights, supplemented by chrome trim, giving consideration to exquisiteness and recognition. The style of the back surround echoes the front face, showing a calm and atmospheric visual effect.

In the car, there is little difference between the 2024 Xingyue L Raytheon Hi·F hybrid version and the current model. It continues to be equipped with a large screen with a length of 1 meter consisting of three 12.3-inch screens, and its performance in science and technology is still relatively good. The car system is a collection of three video media: Tencent Video, Iqiyi, and Bi Li, with rich entertainment and audio-visual resources.

The whole interior adopts the double color matching of dark gray and beige, creating a strong sense of grade. The air outlet of the air conditioner is designed to be hidden, only a row of physical buttons are reserved below, and the central channel area is equipped with a mobile phone wireless charging panel, an electronic bar and a cup holder with a cover plate, which gives consideration to certain practicality.

In the power part, according to the application information, the 2024 Xingyue L Raytheon Hi·F hybrid version will be equipped with a 1.5T engine with a maximum power of 120kW. The data should be the same as that of Yinhe L7, and it will be changed from the current three-cylinder engine to a four-cylinder engine with a power increase of 10kW, or it will continue to be equipped with P1+P2 dual motors, 3-speed variable frequency electric drive DHT Pro and Xinwangda ternary lithium battery. What do you think of the changes in the new car? (Text/Comfort)

5800 must buy! ? Is tablet computer a must-have for "e-teaching"?

CCTV News:Recently, Mr. Wang from Bengbu reported through the "internet plus Supervision" platform in the State Council that Yuying Middle School in Wuhe County asked each student to spend 5,800 yuan to buy a tablet computer, saying that it was necessary for homework and study.

At present, the local government has responded that Yuying Middle School has been ordered to immediately stop the illegal charging of students’ tablet fees, clear all the fees already charged, and dismiss the principal within a time limit.

On the social platform, the issue of "Bengbu No.1 Middle School requires students to spend 5,800 yuan to buy tablets" has caused many netizens to discuss. In addition to questioning the compulsory fees charged by the schools involved in the news, many netizens also expressed their concerns about the current e-teaching.

Student Homework: From "Handmade Age" to "Electronic Age"

"Now the ipad has become a must for primary school students’ homework, and it has to be used for homework and daily punching." Ms. Liu’s daughter is a third-grade primary school student. In order to facilitate timely communication with teachers, Ms. Liu has added four or five WeChat groups and nail groups. Last year, during the online class of the epidemic children at home, she had to "shuttle" her homework on WeChat group, nail group, APPlet and mobile app every day.

"When we were young, when we went to school, the teacher wrote the homework on the blackboard, and then we copied it into the notebook. Now the teacher sends the homework to the WeChat group, and we will tell the children what to do when they get home." Ms. Liu lamented that today’s primary school students’ homework has entered the "electronic age" from the "manual age".

As a head teacher of a primary school in Henan, Xiao Yangang heard many parents’ "complaints" in his first year of employment. "Many parents used their mobile phones to chat on WeChat and watch the news before, and some of them never used nails, let alone small programs." Xiao Yan introduced that, generally speaking, English and Mathematics will be arranged with online exercises after class.

(Parents of students in Xiaoyan’s class are punching in the circle of friends)

In fact, not only primary school students, but also more and more parents of preschool children have joined the "online education" army. Ms. Xiao, 56, spends her daily life attending classes with her granddaughter on the ipad. She laments that she has to learn to "punch in" when she is retired. In order to make her granddaughter "not lose at the starting line", Ms. Xiao’s daughter reported Dashan English and Little Spark Thinking AI classes to her granddaughter. Because she was worried that her children’s eyesight would be affected at a young age, Ms. Xiao would control her granddaughter’s "study time" within 20-30 minutes every day.

Does electronic teaching increase the burden? Parents and teachers disagree.

With the advent of the era of electronic teaching, social software such as WeChat, QQ, and various apps have become more and more frequent in primary and secondary education and teaching, and to some extent, they have even become inseparable ways and assistants for teachers.

In November last year, the news that a Jiangsu student’s parents sent a video angrily attacking the teacher for correcting their children’s homework and quitting the parent group quickly fermented on the Internet, causing public concern and discussion. Subsequently, the news that "children learn three courses and I am drawn into eight parent groups" appeared on the news pages of major media, and netizens expressed their feelings that "it only takes one parent group to crush adults".

In January 2021, the Ministry of Education issued the Notice on Strengthening the Management of Mobile Phones for Primary and Secondary School Students, requiring primary and secondary school teachers not to use mobile phones to assign homework or require students to use mobile phones to complete homework. Earlier, the Ministry of Education also issued a document clarifying that teachers should not hand over the task of correcting homework to parents.

In the eyes of parents who support the ban on electronic homework, the appearance of "electronic homework" has changed the boundary between teachers and parents about educational responsibilities and obligations, such as correcting homework that should have been done by teachers and manual homework that should have been done by students, and now all of them are passed on to parents.

Ms. Liu feels that compared with when her eldest daughter was in primary school more than ten years ago, the pressure of tutoring her younger daughter is obviously greater now. On the one hand, electronic products such as tablet computers have become the "standard" of primary school students, which has increased the financial burden of parents; On the other hand, parents also have to undertake more educational tasks. "Assigning homework through WeChat or App, in fact, the task is transferred to parents. Some of them have to correct homework for their children after a day’s work, which is really tiring." Like most parents, Ms. Liu is also worried that her children lack self-control and will be addicted to electronic products in the future.

However, according to Xiao Wu, a primary school English teacher in Hangzhou, in today’s mobile Internet era, it is impossible and unnecessary for education and teaching to exclude technology. She thinks whether to arrange "electronic homework" depends on the characteristics of the subject and the type of homework. "It is definitely more convenient to read and recite English and Chinese, especially oral English homework online."

Xiao Wu introduced that in her school, some physical education class’s training is also punched in through the APP. "Children write their own exercise content like a circle of friends, and then attach videos or pictures." Xiao Wu said that at present, parents are more supportive of this online and offline teaching mode. She believes that the Ministry of Education should take into account the characteristics of different subjects while introducing relevant bans and prevent "one size fits all" implementation methods.
