It is getting closer and closer to the launch conference of Xiaomi Automobile on March 28, and the hot search of Xiaomi Automobile is rolling.

"New Product Finance" is concerned that on March 19, Lu Weibing, president of Xiaomi Group, said that Xiaomi’s phased goal is to enter the top three sales of pure electric luxury cars.

Regarding the pricing of Xiaomi car, Lu Weibing said that it will be a bit expensive, but I believe that everyone will recognize this pricing after watching the press conference on March 28.

Lu Weibing also said that Xiaomi SU 7 is a C-class high-performance eco-technology car with excellent performance, configuration and experience.

Xiaomi Automobile has held a technical conference at the end of 2023, but it has not announced the price, which has always triggered speculation. Lei Jun once said that 99,000, 149,000 or even 199,000 are all joking.

Recently, Li Guoqing, the founder of Dangdang, also sent a video calling Lei Jun, suggesting that Xiaomi’s car should be priced at 150,000 to 200,000 yuan, not to mention 400,000 to 500,000 yuan.

Combined with Lei Jun’s previous responses and Lu Weibing’s latest views, Xiaomi’s first model doesn’t want to lower its posture. Xiaomi wants to directly sprint the luxury car market and impact the luxury car brand.

From this point of view, Xiaomi Automobile didn’t want to make friends with young people from the beginning.

So, why does Xiaomi want to dream of a luxury tram? What else does Xiaomi need to do to make a luxury brand dream?

01 luxury brand dream, Xiaomi car has no choice.

It is said that China’s new car-making forces and new energy car brands crossed the river by touching Tesla.

Tesla took the high-end route at first, first released the Roadster, a pure electric supercar, and later released the Model S, a luxury coupe, which directly laid the brand positioning of Tesla.

Later, Tesla began to scale up, and then released Volkswagen models such as Model 3 and Model Y, but still locked in the mid-to high-end market. This is Tesla’s market play.

Look again, how did China’s new car-making forces develop?

After the resumption of Wei Xiaoli’s three new car-making forces, Weilai positioned luxury brands from the beginning, despised Tesla and challenged BBA. Xpeng Motors focuses on science and technology, starting with younger models and then developing upwards. LI learned from Apple’s product thinking, and released the first Li ONE mid-to-high-end model from the very beginning, which set the tone for the ideal brand, and then developed continuously.

Now, among the three new forces making cars, Ideal is the most successful, Weilai is under increasing pressure, and Tucki is under pressure to survive, which Xiaomi sees.

The first model of a new car company will directly set the tone for the future brand image.

In the case of Tucki, Tucki started to focus on high-tech and younger models, and then the brand went up. After the launch of high-end models, it faced the pressure of brand going up.

In addition, the new energy vehicles labeled with Huawei have broken a new path, and the brand cars in the world are also taking the middle and high-end route.

Xiaomi’s late entry can greatly reduce the cost of trial and error, and it is no longer necessary to cross the river by touching Tesla like the previous new car-making forces. Xiaomi’s car touches all the new car-making forces.

The brand Xiaomi is synonymous with cost performance in public perception. Later, the road of high-end Xiaomi mobile phone was very difficult. Xiaomi mobile phone made it difficult for Xiaomi brand to be associated with high-end brands. Lei Jun would definitely not let Xiaomi car go back to the old road of Xiaomi mobile phone.

The low-end new energy vehicle market is a red sea, and players from all walks of life are fighting fiercely. Since the beginning of this year, BYD has taken the lead in price reduction, directly reducing the price of low-end Volkswagen models to less than 100,000.

The competition in the low-end new energy vehicle market is extremely fierce, so Xiaomi Automobile naturally has to avoid it. If it directly enters this market from the beginning, Xiaomi Automobile has no advantage.

"New Product Finance" believes that Xiaomi Automobile has a late time to build a car, and the cultivation period of the domestic new energy automobile market has passed. Xiaomi Automobile can only choose to take the middle and high-end route, and there seems to be no other choice.

To realize the dream of luxury brand, Xiaomi automobile has to go through three levels.

It will definitely not be smooth sailing for Xiaomi Automobile to make this luxury brand dream. In the view of New Product Finance, Xiaomi Automobile faces many challenges to realize its dream of luxury car enterprise, including at least three hurdles.

The first level, the product level, to realize the dream of luxury cars, Xiaomi SU 7 needs to win the first battle.

Xiaomi SU 7 is the first model of Xiaomi Automobile, and its importance to Xiaomi is self-evident. Xiaomi Automobile has held a technical conference. In Lei Jun’s words, the performance of Xiaomi SU 7 can reach the performance of at least two or three million luxury cars with fuel vehicles.

At least from the technical parameters of Xiaomi SU 7, it must be able to pass the customs, but it still needs the recognition of consumers and the market.

Recently, MEGA, the first pure electric MPV model ideally released, fell into a crisis of public opinion due to styling association problems. The large order did not break through 10,000, and the number of small orders turned into large ones was limited. Although it broke through 1,000 vehicles in the first week of delivery, its market value has shrunk by nearly 100 billion yuan.

One of the key reasons for the controversy over the ideal MEGA is the starting price of 559,800 yuan, and the high-end positioning needs to be recognized by the market and consumers.

It can be seen that the lesson of the ideal MEGA rollover, Xiaomi Auto is certainly in the eye, and the pricing of Xiaomi SU 7 is still the key.

The second level, brand level, Xiaomi automobile should be born out of Xiaomi and create a brand new brand.

As mentioned above, Xiaomi Automobile doesn’t want to take the old road of brand development of Xiaomi mobile phone, but wants to find another way and take the middle and high-end route.

If Xiaomi SU 7 wins the first battle, it will not only lay the industry position of Xiaomi automobile brand in one fell swoop, but also push the brand height of Xiaomi Group to a new level.

Weilai began to locate high-end, and the brand style has been formed. LI also has a foothold in the mid-to-high-end market, and Xiaomi Automobile also needs to be a blockbuster.

"New Product Finance" has written an analysis before. Although Xiaomi Automobile is based on Xiaomi, it must be born out of Xiaomi and re-create a new Xiaomi automobile brand.

The third level, the long-distance running level, Xiaomi Automobile definitely needs long-distance running if it wants to become a luxury brand.

The new energy car track is more popular than long-distance running, not who. Building a car is completely different from making a mobile phone.

At present, some new car-making forces and new energy automobile brands under traditional automobile brands say that they are luxury brands, but in fact they are not, and they are still far away.

Because to become a luxury brand, it is not overnight, but requires long-term cultivation and long-distance running.

03 conclusion

Looking at the current new energy vehicle market, it is mainly divided into two factions. A large faction focuses on the affordable mass consumer car market, and its representative is BYD. Another faction is focusing on the full-size luxury SUV market, which represents the ideal, and the gap market gives Xiaomi an opportunity.

"New Product Finance" believes that Xiaomi Automobile will have great strategic extensibility if it releases its first model, whether it is to expand the higher-end price range market upwards or expand the niche market of the affordable Volkswagen model range downwards.

I don’t know if you have found out that new energy automobile brands, including many new car-making forces, all say that they are luxury brands, but the market views are inconsistent.

But Tesla never seems to say that he is a luxury brand, but Tesla has formed a solid luxury brand image and made Tesla’s brand advantage.

Therefore, in terms of brand play, Xiaomi Automobile might as well "learn" from Tesla, not always saying that it is a luxury brand, but asking consumers and the market to recognize Xiaomi Automobile as a luxury brand, and then Xiaomi Automobile will truly realize its dream of luxury brand.

On March 28th, Xiaomi Automobile will hold an official press conference, which will reveal the mystery of the price of Xiaomi Automobile and will also determine and influence the future of Xiaomi Automobile.

Do you think Xiaomi SU 7 will be a blockbuster? Can it support the luxury brand dream of Xiaomi Automobile?

A few days ago, the driving sight learned from the official that Haval Xiaolong/Xiaolong MAX will be officially launched on May 15th, in which Haval Xiaolong locates compact SUV and Xiaolong MAX locates medium-sized SUV, which will also become the first model of intelligent electric hybrid four-wheel drive system equipped with the new hybrid architecture Hi4 of Great Wall.

In terms of appearance, Haval Xiaolong’s front face adopts the popular closed shape, and the air inlet below is simple in shape, which further enhances the recognition of the front face with LED headlights with T-shaped daytime running lights. The shape of the side and tail is very similar to that of the god beast, and the width indicator of the taillight is highly consistent. Together with the two-section vertical high-position brake light in the middle of the tail wing and the simple shape of the tailgate, it highlights the young positioning.

Xiaolong MAX is positioned at a higher end, and its design is also full of new energy. The front face adopts a borderless semi-closed middle net, which is decorated with the integrated air inlet at the bottom and the air duct on the outside of the LED headlights. Together with the short version of HAVAL, it conveys a simple and futuristic style. The side shape combines the design elements of the third generation H6 and the God beast, which not only provides a wide side window with a good driving vision, but also combines the tough style of the God beast with the line shape design. The tail light is simple and sharp, the tailgate has a wide and solid profile, the top is equipped with a tail with integrated high-position brake light, and the bottom diffuser has added a middle brake light and chrome trim strips on both sides.

In terms of size, the body length, width and height of Harvard Xiaolong are 4600/1877/1675mm, the wheelbase is 2710mm, and the rim size is available in 18/19 inches. Xiaolong MAX has a length, width and height of 4758(4771)/1895/1725mm, and a wheelbase of 2800mm, which is basically equivalent to Haval.

In terms of interior, Harvard Xiaolong focuses on practical fashion style, dual screen, dual-position wireless charging board, electronic pocket, double storage space and other elements; Xiaolong MAX adopts a T-shaped triple screen layout, LCD dashboard+central control touch screen+passenger entertainment screen, which has a stronger sense of luxury and looks more like a smart cockpit.

In terms of power, Xiaolong will be equipped with a plug-in hybrid system consisting of a 1.5L engine and a front-mounted single motor, with a maximum power of 101 HP and a maximum torque of 132 Nm. The transmission system is matched with a 2-speed DHT gearbox, and the cruising range of pure electric NEDC is 52km and 110km respectively. The Hi4 intelligent electric hybrid four-wheel drive system carried by Xiaolong MAX consists of a 1.5L engine and front and rear dual motors. The comprehensive power of the system is 279 HP and the comprehensive torque is 585 Nm. The transmission system is matched with a 2-speed DHT gearbox, and the cruising range of pure electric NEDC is 105km.

According to relevant data, in December 2021, BYD sold 13,701 Han models, including 10,301 Han EV (parameter picture) and 3,400 Han DM.

Today, let’s take a look at the advantages and disadvantages of BYD Han EV with good sales.

Advantage 1: the feeling of pushing back brought by strong power

As a pure electric vehicle, BYD Han EV perfectly has the very rapid starting acceleration ability brought by the high torque output of electric vehicle motor. The official acceleration score of 100 kilometers takes only 3.9 seconds, and this performance can even be compared with luxury and super-running. For users, what is more important is probably the strong sense of pushing back brought by this strong power.

Question 1: The charging noise is loud.

The so-called super charging technology of BYD Han EV has some problems in actual use, the prominent one is the loud noise, and the design of the charging head of BYD Han EV is not reasonable, so charging is relatively inconvenient.

Problem 2: The assisted driving is not perfect.

Generally speaking, new energy vehicles have more obvious advantages in intelligence than traditional fuel vehicles. However, BYD Han EV is not only an L2-level automatic driving assistance system, but also does not perform well in actual driving. For example, Han EV can’t turn on ACC alone, but must keep driving together with the lane. For example, Han EV’s lane line recognition is not in place, and it can’t be used as long as the road conditions are almost the same.

Problem 3: The brake foot feels bad.

Perhaps the coordination between BYD Han’s energy recovery system and braking is not done well, which leads to its stiff foot feeling at the beginning and end of braking, and even a "nod" situation.

Question 4: The actual cruising range has shrunk seriously.

Like many new energy vehicles, BYD Han EV also has a shortened cruising range. Due to congenital factors such as structure, it is difficult to ensure its power-off speed even if Han EV adds many insulation measures, especially in winter and colder northern regions. According to the feedback from car owners, the official cruising range of 550 kilometers is only 400 kilometers, and most car owners say it can only reach about 350 kilometers.

Question 5: The accelerator pedal area is too small.

Byd Han also has a very serious safety problem, that is, the distance between the pedal and the baffle used to protect the mechanical structure above is too close. Basically, as long as the foot is about 40 yards, the toe will touch the protective plate if the foot is slightly lifted up. However, if you switch between braking and throttle very quickly and frequently in the actual driving process, your feet will basically hit the protective plate every time, which is very easy to cause misoperation of driving and affect driving safety.

Problem 6: Too comfortable chassis adjustment affects vehicle handling.

In terms of suspension, BYD Han EV adopts the multi-link suspension structure before McPherson. Although some people call it the "chopsticks" chassis, you will know that this statement is not true after driving BYD Han EV. The main problem of BYD Han EV chassis is that it is too comfortable to adjust, which will make it difficult for drivers to control the vehicle perfectly when the vehicle is accelerating rapidly, which is obviously incompatible with BYD Han EV’s strong acceleration power from the aspect of maneuverability.

Problem 7: The rotary central control panel is not practical.

The central control panel in BYD Han EV car adopts a rotary design, which sounds cool, but in fact, it is very practical, and this function is basically not needed for daily driving. Han EV integrates most of the functions inside the vehicle into the central control panel, but its touch performance is not so good, and the car system also has the problems of slow running speed and many bugs. In this case, it is very inconvenient to have no physical buttons in the car.

Question 8: Small trunk space.

Because the battery pack occupies part of the space, even compared with most new energy vehicles, BYD’s trunk space is still relatively small, with weak loading capacity and good practicability. In addition, there is no trunk in the front cabin of BYD Han EV, mainly because BYD Han still has a DM version, so it must be compatible with oil and electricity. For the sake of placing an engine and gearbox in the front cabin, the front cabin of BYD Han has to be similar to the traditional model, and the final result is that BYD Han still has certain limitations in the front cabin design.

Haidian, a secluded and luxurious fragrant hill, was awarded the "Top Ten National High-end Works in 2023" by an institution; It sold well for the first time and won many sales titles in Beijing and Haidian.

Luxury houses will always be hard currency against the market, but luxury houses, like them, also have high value, often occupying the top position, and the luxury houses with top product strength have always been far ahead. Throughout the Beijing market, Xiangshan Yue is undoubtedly one of the leaders in luxury houses, occupying the position of "Zhen Edition" in Xiangshan District, and planning all four floors, which is really rare.

01 Cut to the chase and enter the room.

Xiangshan is close to the mountain without backing it, with a straight line distance of about 2000 meters from the main mountain of Xiangshan, and has a good location and angle for enjoying the scenery. The main entrance is located on the west side of the community, facing Xiangshan, which bears the generous gift of nature and lays the foundation for Xiangshan to blend in with nature and hide in Xiangshan.

The entrance landscape wall is 6 meters high, and the East Lake stone is washed by fire, and the big slab stone reflects the verve and quality; Specially selected tall trees with elegant and modest branches and vines as the main scene of welcome, showing the texture of landscape painting in the change of light and shadow, full of elegance and luxury. The scenery-borrowing design of the grille at the gate melts the boundary between Xiangshan Yue and Xiangshan, and Xianhe Door Instrument has the holiday feeling of a secluded luxury hotel.

When I first entered the gate, I saw a high hall and a wide courtyard, and the water was flowing head on, and I was full of melancholy. Hotel-style entrance lobby means entering the room. Directly enter the campus from the front door, enhance the sense of returning home ceremony with the lobby, and construct a noble and luxurious venue. In the center of the lobby, there is a non-legacy construction method, and the master customizes the hand-made Xiangshan plaque, adding a hidden and expensive momentum.

Forward in the lobby, you can see the reflecting landscape courtyard, with quiet mirror water flowing. The flowing water is gurgling, reflecting the buildings on both sides, framing the landscape into a picture, calming the water surface to show the natural charm, and then introducing Xiangshan to the hospital at four o’clock.

The water surface is facing the main scene, painting a screen for Xishan Mountain. The first meaning of "Xishan Mountain" is Xishan Mountain, and the second is to echo the water surface. The landscape poetry is set in a square inch, and the water symbolizes the prosperity of the great country, the clear river and the sea, and the mountain echoes the hidden luxury pattern and the atmosphere in the chest. The overall shape is taken from the official head of the Song Dynasty, which adds dignity.

02 Centennial Context of Axis Instrument System

When the water courtyard moves forward, you can feel the richness and width of the garden axis. The cross axis layout, the horizontal axis takes the vastness of the masterpiece A Thousand Miles of Rivers and Mountains handed down from ancient times in the Northern Song Dynasty, and the vertical axis takes the height of the masterpiece A Journey to Xishan Mountain, which was founded in the Northern Song Dynasty. It not only has the sense of writing "city-courtyard-garden-mountain" imitating the Forbidden City, but also has the richness of visiting the park.

Visiting the park, or moving around, or suddenly enlightened. Three-dimensional scattered courtyards enrich the feasibility of space and create a unique sense of seclusion. Between pitching, it is pleasant and calm. In line with Su Dongpo’s "Sixteen Pleasures in Life", the Northern Song Dynasty famous artist created sixteen private gardens. The mountains and gardens meet each other, simple and high-end.

04　纯质低密范本　墅级人居体验

香山樾供应之时，受到京城几十家激烈拼抢。在“归家九礼”等产品打造之前，地块本身就已具有了“孤品级”素质。

The plot ratio is only 1.05, which violates the low-density plot for more than ten years and the lowest density project in Xiangshan villa area in recent years; About 73,800 ㎡, which is the largest in Haidian in recent ten years, and may also be the last large-scale pure high-end land in Xiangshan Villa. Close to the mountain, not relying on the mountain, just enjoy the mountain distance, Haidian piedmont plate has the best view of the mountain, the best viewing angle and the best landscape resources.

At the same time of the golden combination of "the most abundant scale+the lowest density", the topographical features of "Xiangshan on one side and parks on three sides" also make Xiangshan Yue the most distinctive place to echo nature, creating a sense of living experience that is infinitely close to villas.

In architectural design, together with contemporary masters, taking Song-style aesthetics as a reference, through the "six methods of architecture" of meaning, shape, color, rhyme, quality and space, the four-story villa is conceived, which is rare in the region. The roof was painted in the Song Dynasty with the picture of Ruihe, with the nine ridges resting on the top of the mountain highlighting the integrity and peace of the building. The tiles, feiyun ridges and eaves of Long Lin show the elegant and stretching beauty of the building, which, together with custom-made hanging fish bottles, forms a beautiful meaning of "fish leaping over the dragon gate and rising step by step", creating an architectural image of "the roof stretches over the western hills and forests, and all the talents are outstanding".

Blue-eyed stone is selected for the lateral elevation, and traditional culture is introduced into the southern elevation. Through the innovative application of custom-made ceramic plates made of azure imitation Ru kiln and the line depiction of elegant gold aluminum plate, the noble feeling of "stone inlaid with gold, gold inlaid with jade" is realized. Coupled with the super screen and IMAX level, it reflects the four seasons of Xiangshan and contains infinite realm.

On the internal space level, Xiangshan Yue put forward the innovative space concept of three luxury houses: promising unbounded spacious hall, just right width and self-satisfied housekeeping space, paying tribute to the life home of contemporary secluded families.

With a floor area of about 231㎡, the apartment has a super-wide area of about 14.3 meters, and the living room has a wide scale of about 6.6 meters, which brings the Xiangshan scenery into the private home. The living room part adopts Xuge sliding window. After many times of research and development, the window width of the living room has reached a high proportion of 78%, forming an "IMAX giant screen" floor-to-ceiling window effect.

Real-life map of creative model room

The design of nearly 100-square LDK integrated space makes the space cruise more and more comfortable to use. The aspect ratio of gold surface is about 0.9-1.37, and the interior space is extremely high, so even the round-table furniture of big families can be easily laid out.

Concealed luxury into the world, the character is most China; Four seasons scenery, pitch are all picturesque; The top of the pavilion ridge reflects the ingenious inheritance; Xiangshan is located on the out-of-print land of Xigui, Beijing, creating a rare plot ratio of about 1.05, with a four-story villa with a large flat floor. The cover work of a new generation of secluded luxury houses in China is composed of the Millennium scenery of Xiangshan and the essence of human settlements in the past dynasties.

Byd Han DM-i just went on the market a few days ago, and this new launch has made the models more detailed. There were two power versions of Han EV and Han DM before, but this time it was replaced by three. Besides Han EV, Han DM was divided into DM-i and IDM-P; DM-i focuses on the economic power horse, while DM-p focuses on the performance level. The official guide price of the whole department is in the range of 214,800-329,800 yuan. Today, let’s talk about BYD Han DM-i and see what it is like.

In terms of appearance, the front face shape still maintains the previous big mouth-shaped style design, but some adjustments have been made in the surrounding, especially the outer surrounding is not the same as before, and it is much more rounded. The headlight group with full LED light source has not changed, and it is still so intense. The whole body size is slightly longer than the previous Han DM, with the length, width and height of 4975*1910*1495 mm and the wheelbase of 2920 mm. Due to the change of shape, the side lines of the car body appear smoother. The standard of the whole system is 19-inch wheels, which are particularly coordinated with the body, and the manufacturers are kind enough.

Relatively speaking, the rear of the car has changed a lot, and the style of the taillights has changed very obviously. It still maintains a penetrating style, but after lighting, the line styles inside are completely different, with a feeling of being intertwined and elegant, and the recognition is very high.

The whole interior is still excellent in grade sense, exquisite in workmanship and high-grade in materials. For example, many places are wrapped in leather, brown seats, concave and convex carbon fiber plaques on the console and other materials, which shows that the manufacturers really cut costs. At the same time, the car is also equipped with multi-color atmosphere lights, which are particularly cool after lighting. Even the lowest exclusive version configuration has been very comprehensive, such as adaptive cruise, lane keeping, active braking, lane departure warning and so on. The high-end distinguished version will also increase the functions of heating, ventilation, memory of the main driver’s seat and so on, and the configuration is quite rich. The flat-bottomed steering wheel has a moderate size and a comfortable grip.

This car is positioned as a medium-sized and large car. From the interior design, material details and texture, it is not a problem to catch up with Audi A6L. The 12.3-inch full LCD dashboard has clear images and rich contents. The new model comes standard with a 15.6-inch central control large screen, which is equipped with DiLink car system, which is quite good in the same class and price model. In terms of storage space, there is an exquisite cover plate that can be slowly opened in front of the handle, which is very similar to the texture of higher-grade models. There are two cup holders, Type-C and USB charging interfaces inside, and the space for the central armrest box of the cover is not too large, but it is enough to put some daily odds and ends; There is a wireless charging board in the front row. This configuration performance is very satisfactory for a new energy car with more than 200,000 yuan.

Spatial performance, the height of the test driver is 1.83 meters, and the head space in the front row is about one punch, which is regarded as the mainstream performance among the same class models. The space in the back row is very spacious, and the legs are close to the front backrest by three punches. Because there is a concave space stealing design at the top, there is a punch in the head. The seat is soft and the backrest angle is good, so the comfort performance of the whole rear seat is quite excellent. The rear row is equipped with independent air conditioning control, boss key and rear privacy glass; In addition to the minimum model, it is also equipped with advanced audio, which is very kind.

This time, the power part has also been greatly adjusted compared with before. No matter Han DM-i or DM-p, it is equipped with Xiaoyun 1.5T turbocharged engine, which is special for plug-in hybrid power. It’s just that the layout of the motor is different. For example, the Han DM currently on sale is a 2.0T engine driving the front wheel and the motor driving the rear wheel. The brand-new Han DM-i is a 145kw motor to drive the front wheel, and Han DM-p is two motors. The front motor is 160 kW and the rear motor is 200 kW, so the personality will be stronger. In terms of pure electric cruising range, Han DM-i has two options: 121km and 242km versions. The pure electric cruising range of Han DM-p is 202km, and the acceleration time of 100 km reaches 3.7 seconds, which is one second higher than that of the old Han DM.

To sum up, the launch of the new BYD Han DM has made many consumers see a new choice, because the previous Han model only had one power version of DM, and this time it has become three. So which version is appropriate to buy? Personally, it’s enough to use the 121km version everyday, and it’s no problem to use the 121km battery life in short distance in cities, and the fuel consumption is 4.2L/100km. After a comprehensive calculation, a box of oil and full charge, the maximum cruising range can exceed 1300 kilometers, which is quite excellent. If you want better power performance, you can buy a performance version of the DM-p model. The official acceleration of 100 kilometers can reach 3.7 seconds, which is very fast for such a big car, and its low fuel consumption is 5.2L/100km, which is not too high. As for their dynamic performance? I will share it with you after I have a chance to test drive in the future.

　　Content summary:The rapid development of AI technology in the field of artistic creation has expanded rapidly, and the combination of China ink painting and AI has also produced many phenomena and problems. This paper will discuss the application prospect of AI in China ink painting from multiple dimensions, including how the symbiotic creative technology of AI and ink painting will affect the artist’s creative process, whether it will shake the boundary and core value of ink painting, and examine the challenge this combination brings to the traditional spirit and modernity of ink painting, as well as the gap between AI’s innovation and artistic life expression.

　　Key words:Artificial Intelligence Emergence and Challenge of Symbiosis and Innovation of China Ink Painting

　　In today’s wave of iterative technological change, artificial intelligence (AI) permeates all aspects of our lives. The art industry is also facing reconstruction and change, especially the visual, auditory art and design industries, which are becoming increasingly digital. New opportunities and crises coexist. The blending of art and AI will lead to an unprecedented subversive artistic change, and the future of China’s painting and calligraphy art is infinite.

　　As we all know, the art of Chinese painting is supported by a profound traditional knowledge system, which is continuously passed down and developed through the way of assimilation and acculturation. This has created its unique cultural psychology, thinking and behavior characteristics, and formed an interlocking brushwork and programming language. To borrow Yu Yingshi’s words, we should pay attention to the cultivation of knowledge and taste. "We should take the specialty as the origin, embrace thousands of families with relevant knowledge, and emphasize the knowledge and agreement, communication and specialization" (preface to Yu Yingshi’s Selected Poems and Paintings of Zhang Chonghe, life, reading and new knowledge Sanlian Bookstore, 2015 edition, p. 5), and professional learning should be based on a broad academic platform, so as to "unify all the disciplines and have them." With the rapid development of social science and technology, China’s ink painting spirit, which is bound by consumerism and utilitarianism, is the upward way to settle the free mind and has irreplaceable current significance.

　　However, emphasizing the present significance of ink painting cannot avoid the challenges faced by contemporary ink painting creation. On the one hand, the traditional painting method can not be compared with the generation efficiency of digital technology. Traditional painting needs a lot of time in the stage of material preparation and idea landing, while digital technology can create quickly, modify at any time, and save multiple versions for comparison and selection. On the other hand, in the face of increasingly diversified and rapid aesthetic needs, the innovation and integration of ink painting can be isomorphic in the cooperation and symbiosis with AI, and explore the appropriate development path. AI can rely on the huge database analysis, the existing vocabulary and creative experience of ink painters, the empathy isomorphism of artists’ inner feelings, and even the legal essence of the value system of ink painting to promote artists’ understanding of more dimensions of the vicissitudes of nature, deduce the absolute theme, effectively evaluate the creative scheme, technique, material application and display mode, and help artists deepen the language dimension of their creation and understand and explore social humanities and styles more deeply and diversely.

　　AI’s powerful computing power and huge information programming can quickly generate traditional painting skills, and can generate and understand huge data to create visual styles far beyond the usual ones. Among them, the imaginative "emergence" phenomenon shows the infinite possibilities of artistic creation in the AI era, which can be said to be the coexistence of longing and fear. At present, the use of AI tools is still in the initial stage. Most of the art industry only regards AI as a convenient and efficient technical tool, which is a synthesis under the constraints of the artist’s existing preset framework, such as asking questions to ChatGPT or sharing preliminary ideas. As an advanced language model, ChatGPT can understand the needs of artists and provide relevant suggestions, such as suggestions on artistic style, theme or technical scheme. This process can help artists to inspire and broaden new creative inspiration, and artists can use the tools of Midjourney to generate sketches. Midjourney has a series of operation processes that can help artists turn their ideas into visual sketches. Later, artists can share their sketches with ChatGPT for feedback. ChatGPT can provide suggestions on theme, composition, color and texture to help artists optimize their creative schemes. After several rounds of feedback and optimization, artists can use Midjourney to complete the second creation of pictures.This process requires artists to have clear creative ideas and clear self-awareness.

　　On the one hand, meet the challenge, on the other hand, embrace the possibility. AI can quickly learn and imitate human painting skills and works of art. This provides a new possibility for the future of ink painting. On the other hand, by analyzing the learning and creation process of AI, we can understand and study the creation rules and aesthetic rules of ink painting from various angles. In addition, AI’s powerful database and computing power, as well as its amazing internalization ability, have amazing algorithms surging, which enables AI to present visual effects unmatched by human beings in a short time, which makes it possible for AI to promote ink painting and even cross-media development. We should actively face the benefits brought by AI, make full use of the advantages of AI’s reproduction based on excellent human visual image experience, and the visual logic and formal patterns of AI calculus, actively explore and try new expression methods, and maintain the vitality of symbiosis and isomorphism between man and AI. AI provides a new vision for the innovation of ink painting. In this era of great change, we should embrace the symbiosis and isomorphism between AI and human beings, so that the art of ink painting can maintain its open vitality and embrace more chaos and unknowns.

　　In the history of human art, new technology can always promote the development and change of art. From architecture, design, photography to movies, from electronic music to digital art, technological progress has provided new possibilities for artistic creation. As a new technology, the application of AI in artistic creation also provides infinite imagination for ink painting.

Qiushi Digital Printing Sculpture 2023 "Heel Things Increase China — — Qiu Ting Art Exhibition "exhibition site

　　The application of AI also puts forward the thinking of ontological value and boundary for the spirit of ink painting. The unique aesthetics and expression of ink painting are deeply rooted in the cultural soil of China, especially in the introspection and spiritual transcendence of Confucianism, Buddhism and Taoism, which is the most valuable scenery in China’s cultural and artistic genes. The iterative development of science and technology does not necessarily touch the core part of the value system of ink painting art, such as traditional core concepts, history, skills, and the study of calligraphy and painting evaluation from semantics to concept generation. No matter what mode of Chinese painting exploration, we can’t avoid these core values, as well as the research and exploration on the origin of traditional culture.

　　However, AI-generated paintings often have an unreal sense of science and technology. At present, many works with some kind of electronic-generated plastic sense are typical. China’s ink painting is characterized by "loose", "waxy" and "hairy", the presentation of aesthetic images such as antiquity, obscurity, elegance, Xiao San and coldness, and the lack of AI creation, which is related to the current lack of AI’s understanding of nature and subtle emotional understanding of literary mind. Artists will integrate their understanding of nature and their perception of culture into their works in the process of creation. For example, Guo Xi emphasized the relationship between the painter and nature in Lin Quan Gao Zhi, and how the painter expressed his mind through nature. He said: "The landscape is the grand view of heaven and earth, and the things are born from it. It is also the goodness of people’s hearts, so it can be tempting to swim alone, get carried away and be leisurely. " This makes the artist’s works have the depth and vitality of philosophical thinking. However, the works created by AI still seem to lack this depth and vitality. Ink painting is based on the nature of mind, and its pen and ink pay attention to viewing things by oneself, viewing things by things, and changing with emotion. The use of symbols and programs is based on the subject’s emotion to grasp and recreate objects, and the learning and creation process of AI is based on data and algorithms. For the moment, no matter how novel and unique its creation style is, what may be missing is the most precious spiritual temperament of ink painting.

　　Therefore, the discussion of AI creation can’t avoid the irreplaceability of the integration of knowledge and practice as an artist’s physical spirit, the emotional expression of the artist’s subtle muscle memory, how to present and measure the fickle nature in the world through hands and brushes, express the complex cultural sense in history, society and religion, and the scale and emotional entanglement of the artist’s integration into the body. AI painting is based on pure operation. Although the phenomenon of "emergence" brings imagination and creativity beyond expectations, it is fascinating and scary, but its creative source is data. However, human creation is based on cognition, which is a comprehensive perception of emotion and body. In particular, it needs to use human body to create in a large amount. It is the artist’s perception and application of body, the expression of consciousness through body, and the contest between body and media. These are probably not available in current AI creation. Perhaps in the future, through the docking of human brain and machine, the generation and creation of large models based on neural networks or billions of parameters can be realized without hindrance, and inspiration can be drawn from AI algorithm and brain neural networks respectively, which is what future artistic creation can look forward to.

In 2023, the White Cube London’s Beaumont West Space "anselm kiefer — — Finnegan’s wake night "exhibition site

　　At the end of June this year, I saw Kiefer’s solo exhibition based on Joyce’s finnegan’s wake, drawing nutrients from poetry, philosophy, religion and science to generate art, while rebelling and subverting, asking about the life cycle of death and rebirth. This shocking visual field is stubborn and bitter, which completes the reproduction of Joyce’s poetic spirit. Only artists with compassion and historical perception can resist the depths of the soul. This kind of human expression and narrative power, which makes the viewer exhausted, will also make us reflect on the limitations of AI’s involvement in the artistic spirit. As Norman Bresson of the University of London once pointed out: The cognition constructed through the symbolic system (signifier and signified) will ignore or ignore "feelings, emotions, intuition and feelings". The human brain has strong plasticity, in which the hidden potential and the thoughts formed by the nerve subject unconsciously make the nerve subject unique in visual experience. Great artistic creation needs the awakening of artistic intelligence and the ultimate questioning of life spirit. If AI is a tool for artists’ research and creation, artists will actively intervene in the application of AI, which will lead to symbiosis with it and enhance their self-creativity. However, the great potential of AI can’t help but make people imagine: when AI cooperates with artists humbly and responsibly, will it also use artists as creative tools? We may also wish to look at it from the perspective of AI as the main body: Is thinking under the inertial framework of an artist a bit like "Be honored where there is no Buddha "? Are humans sometimes too self-righteous?

　　How to "Open" Modern Literary Classics

　　Borges, a famous Argentine novelist, said: "Classics are books that a nation or several nations have decided to read for a long time. They are books that people from generation to generation read with early enthusiasm and mysterious loyalty for different reasons." Since the late Qing dynasty, modern literature has only been more than a hundred years. Compared with the ancient literary classics that have been precipitated for thousands of years, the modern literary classics that have been washed out for more than a hundred years are very different.

　　Facing the classics of modern literature,

　　What should we do?

　　First of all, the simplest thing is to face the work directly. Classics are sometimes daunting, so we should have the sincerity and patience to read them. Secondly, the works will be included in the coordinates of literary history. Place the work in a broader coordinate system instead of understanding it in isolation. Third, look for gaps and prototypes. What is the gap in this work? Where is the unexpected place of the author? Can a work extract a certain prototype until it finds its own way of dialogue with the work? The so-called application method or looking for a gap prototype is an attempt to establish an understanding based on one’s own feelings about the work. Reading classics is actually a way to express ourselves, rather than reading classics as a task. It is the classics that constitute the background color of a person’s humanistic quality. Therefore, classics should eventually return to the way of dialogue between readers and works. When you use all kinds of reading methods freely, you may find your own way to talk about classics. This way belongs to you alone, and no one can take it away.

　　Rearrange the order for Chinese literature in the 20th century.

　　Lu Xun, Guo Moruo, Mao Dun, Ba Jin, Lao She and Cao Yu (hereinafter referred to as "Lu, Guo, Mao, Ba, Lao and Cao") are six modern literary writers we are familiar with. Until today, our understanding of modern literature is still in the hierarchical order of literary history laid by these six writers. They occupy an important position in the territory of modern literary history. However, according to the classic view of constructivism, their classic pattern is not static.

　　The selection of "Top 100 Chinese Novels in the 20th Century" was a literary classic construction activity in the late 1990s. At that time, the 20th century was coming to an end, and Hong Kong’s Asia Weekly invited heavyweight scholars and writers to jointly select the top 100 Chinese novels in the 20th century. Personally, I attach great importance to this list, because the judges include not only mainland scholars in China, but also scholars from Hong Kong and Taiwan and overseas scholars. It provides a larger evaluation field of vision. After the selection results were released, we found that the first place was Lu Xun’s Scream, the second was Shen Congwen’s Border Town, the third was Lao She’s Camel Xiangzi, the fourth was Zhang Ailing’s Legend, the fifth was Qian Zhongshu’s Fortress Besieged, the sixth was Mao Dun’s Midnight, and the seventh was Bai Xianyong’s Taipei Man. — Liu E’s Travels of the Old Handicapped.

　　These ten classic works coincide with the modern literary classics we have known before, but they are somewhat unexpected: For example, Taipei Man, Biography of Hulan River and Travel Notes of the Old Disabled are not only on the list, but also in the top ten! This result surprised some people. Moreover, among these 100 works, there are many works by popular writers such as Zhuan Lou Zhu, Jin Yong, Gu Long, Liang Yusheng, Qiong Yao, Yi Shu and Li Bihua. "Hundreds of Excellent China Literature Books in a Hundred Years" is also a reliable classic reading bibliography. These are the 100 most important Chinese literature books in the 20th century jointly recommended by China mainland scholars and publishing institutions in the 1990s.

　　Not all masterpieces

　　Are the best works of writers.

　　Masterpieces are often the guiding choice of classic texts. Generally speaking, masterpieces are works that represent the writer’s creative level, but not all masterpieces are the best works of writers. When evaluating a work in the history of literature, the social influence of the work is a very important consideration index, but a work with social influence may not necessarily have a higher literary level.

　　For example, when we talk about new poetry, we will definitely talk about Hu Shi’s Trial Collection, because Hu Shi is the first person to write new poetry in a century, and there would be no modern new poetry without Trial Collection. However, if we take the new poems in Trial Collection as the standard of new poems, it is obviously to reduce the standard of new poems to the toddler stage. Therefore, although Hu Shi’s works are masterpieces of new poetry, they are definitely not the essence of new poetry. Another example is a mature writer like Ba Jin. His Home is indeed an excellent work, but it is not the most mature work of Ba Jin. Ba Jin’s writing can be divided into three stages: youth, middle age and old age. Young Ba Jin wrote the love trilogy Fog Rain Electricity and the torrent trilogy Home Spring Autumn. However, Ba Jin’s best works should be the trilogy of life "Cold Night", "The Fourth Ward" and "Resting Garden" written in middle age.

　　Comparing Home with Cold Night, there is no doubt that Home is more influential, because it provides a proposition of the times, showing the collapse of a big family and the tragedy of youth enlightenment. Therefore, Home has a strong social response. Ba Jin, who is in the period of youth writing, has the first emotion, but when emotion occupies the center of writing, it is an obstacle to the depth of writing. Therefore, if you read Home carefully, you will feel that there are both young people’s unique enthusiasm and youth’s unique shallowness. In the 1940s, Ba Jin’s creation entered a mature stage. Cold Night is a story about a man who is caught between his mother and his wife. But this is only the surface of the story. What the novel really wants to express is that during the war years, young people full of blood gradually lost their dreams under the torture of life. Cold Night was born at the time of the victory of the Anti-Japanese War, and the whole novel was very sad. People usually think that the Anti-Japanese War has been won, the suffering has ended and a great nation has stood up. But in Cold Night, Ba Jin put forward a profound proposition: Does the victory of the Anti-Japanese War mean that all the problems in life can be solved? Ba Jin stepped into middle age from youth. Although his emotion changed from enthusiasm to condensation, it made his works more infectious and moved us more. Cold Night is also Ba Jin’s masterpiece, but compared with Home, readers are unfamiliar with it.

　　A good writer should constantly break

　　Readers’ reading expectation

　　There is an important concept in reception aesthetics called "reading expectation", which means that before we enter a literary work, we will have a general expectation for this work by virtue of our existing reading accumulation. For example, we haven’t read Lu Xun’s novels before, but from our understanding of Lu Xun, we know that Lu Xun is a great enlightener, thinker, revolutionary and a great writer. These constitute the most basic judgment for us to read Lu Xun. When Lu Xun’s works conform to this judgment, we will think that our judgment and understanding are correct. On the contrary, we will be surprised: Lu Xun actually wrote like this!

　　Formalism focuses on the artistic expression of the text and the strength of the form of the work. For example, when we look at a work, we feel that it is very old-fashioned and lacking in merit. And sometimes we will find that some works are very clever, similar to those we have read before, but different, and feel very novel. In fact, this is the so-called defamiliarization — — Our existing literary understanding is not enough to explain it, and it presents us with new challenges.

　　For example, Lu Xun’s New Stories, many of which are very playful, are not quite the same as our understanding of Lu Xun’s serious style. This constitutes the so-called defamiliarization. A good writer should constantly break the reader’s reading expectation. Therefore, great writers often don’t follow the old habits, but have multiple faces. One Hundred Years of Solitude is a great masterpiece, but Marquez has not only One Hundred Years of Solitude, but also excellent works such as Love in Cholera Period, Colonel who has no one to write to him, Old Man with Giant Wings and Dead Leaves. On closer reading, you will find that the styles of these works are quite different. One Hundred Years of Solitude is the pinnacle of magical realism, while The Colonel who has no one to write to him is a solid realistic narrative, and Love in Cholera Period is called "the greatest love novel in the world". If you read Love in Cholera with the expectation of reading One Hundred Years of Solitude, you will find that it completely disappoints your expectation, which in turn gives us a brand-new reading experience. Marquez is always challenging our reading expectations. Formalism criticism focuses on whether a work breaks our expectations and provides a strange reading experience.

　　The works of women writers

　　Suitable for interpretation from feminist perspective

　　Today, men’s discrimination against women still exists and is often ignored by us. Feminism tries to embody this discrimination in the context of our ignorance. Therefore, the works of female writers are very suitable to be interpreted from a feminist perspective. For example, Zhang Ailing’s works sometimes give us an anti-feminist feeling.

　　In "Love in a Fallen City", Bai Liusu tried every means to marry Fan Liuyuan, and they tried every means and struggled. Finally, the Pacific War broke out, Hong Kong fell, overturned a city and made a love. From the standpoint of feminism, the ultimate meaning of a woman’s life is not given by a man, but what Bai Liusu wants in Love in the City is to marry Fan Liuyuan. Isn’t this an anti-feminist writing? This anti-feminist writing reflects Zhang Ailing’s irony of feminism. Zhang Ailing is actually standing in a higher feminist position. She believes that Bai Liusu’s story really falls into the so-called "feminist dilemma", that is, it seems that a woman can only achieve perfection in a certain sense if she is attached to a man. Zhang Ailing expressed her distrust of radical feminism by describing the process that Bai Liusu tried to enter the role that male chauvinism wanted women to enter.

　　Lu Yin and Xiao Hong’s works are full of feminism, but such feminism can’t really change the situation of women. Comparing Xiao Hong and Zhang Ailing, Xiao Hong’s feminism is highly prominent. Before she died, she said a few words, one of which was "the sky of women is low". Xiao Hong, trapped in the depths of feminism, met different men all her life, but never gained emotional security. Zhang Ailing is different from her. Zhang Ailing understands the illusion and imagination of this feminist writing, so her Love in the City expresses her feminist position in an ironic way. This is an important angle for us to interpret literary works.

　　Avoid falling into the "orientalist trap"

　　Adopting the perspective of colonialism and post-colonialism, this is a new perspective to interpret the text with the development of cultural studies. Let’s take a movie example to illustrate post-colonialism. The fifth generation directors, such as Zhang Yimou and Chen Kaige, made many so-called "folk customs" in their films in the 1980s, such as the sedan chair and wine offering in Red Sorghum, the light sealing and foot beating in Red Lantern Hanging High, and the rain praying in Chen Kaige’s film Yellow Land, etc. The fifth generation directors hope that the oriental culture will be revived on the screen. However, if we look at it from the post-colonial point of view of Said and others, when the fifth-generation directors desperately show the folk wonders of the oriental nation in their films, they just fall into the so-called Orientalism trap.

　　What is Orientalism? Generally speaking, westerners’ understanding of the East does not come from actual observation of the East, but from reading and watching literary and artistic works that describe the East. Westerners artificially establish the leading position of the West, and when they describe the East, they often create a so-called "grade difference" — — The East is a fascinating foreign land waiting for the West to discover. The meaning of this sentence is that only when the west discovers it can the beauty of the East be presented. This is the so-called Orientalism. Zhang Yimou and the fifth generation of directors he represents, in their films, present the orient, which is actually a kind of so-called self-orientalization. They present China’s aesthetic feeling in the way of "self-orientalization", at the same time, they give westerners a way to understand and observe China through movies, which will inevitably lead westerners to fail to objectively and truly understand China.

　　A similar situation occurs in literary works. For example, Jing M.Guo’s Tiny Times, which is deeply loved by young people, can also be viewed from a post-colonial perspective as a book with a wide reading rate and influence among young people. Under the background of globalization, Jing M.Guo completed his own naming for this era. He named this era of globalization as a small era, reminding us to rethink the center and edge.

　　With the listing of all kinds of new mobile phones, Xiao Chen, a senior "mobile phone fanatic", is busy buying new ones, but more and more old mobile phones at home have become Xiao Chen’s troubles. "If you lose it, it will pollute the environment and you won’t be able to bear it. It’s really a chicken rib to put it at home and take up space." Recently, the Beijing Morning Post reporter visited and found that many citizens are facing the same troubles as Xiao Chen. In the wave of changing mobile phones quickly, many young people want to sell their old mobile phones and worry about information leakage, which puts them in a dilemma. In this regard, people in the industry reminded that it is more dangerous to sell mobile phones in Bidiu. When selling old mobile phones, we should guard against the recovery of deleted data and the disclosure of personal photos and information. At the same time, it is suggested that citizens should choose their own mobile phones based on their own needs and try not to change their mobile phones frequently. If you really want to sell, it is relatively safe to choose the old-for-new method through the official mobile phone store.

　　Case of selling second-hand mobile phones was transferred away by more than 100 thousand yuan

　　Xiao Liu, who changed his job in March this year, changed into a new mobile phone. After getting the new mobile phone, he was careful to sell his old mobile phone. "I sold my mobile phone to the dealer who recycled the second mobile phone in Electronic City." He told the Beijing Morning Post reporter that before the transaction, he actually deleted photos, videos, contacts, text messages and other personal privacy-related contents from his mobile phone and restored the factory settings. But one day after half a month, he suddenly found that the phone could not be dialed. When he went to the business hall, he found that the SIM card of this mobile phone had been invalidated and had been reissued in a different place. Mr. Liu hurriedly reissued a new SIM card, but he was surprised to find that the funds in four accounts were quickly transferred out of 24 funds in different ways, totaling more than 100 thousand yuan. The operation record of the bank is that someone logged into his online banking and made many transfers.

　　"I really don’t know where I went wrong. I have deleted all kinds of information in my mobile phone. But I still encountered such a situation. " Mr. Liu thought about it and thought that the loss of more than 100 thousand yuan should be caused by the sale of second-hand mobile phones. "The original mobile phone was bound with my bank card and Apple Payment, and it should have been deciphered by a caring person."

　　Dare not sell old mobile phones, only for relatives.

　　Mr. Wu, a citizen, told reporters that before he bought an Apple mobile phone online, the original old mobile phone was eliminated. Looking back, htc, Xiaomi, Samsung, Huawei, Apple 4s and Apple 5s have six or seven idle mobile phones at home. For idle mobile phones, Mr. Wu first chose to use them for the elderly and considered selling them, but he was still worried about information leakage. "I wanted to sell it, but I was afraid that the criminals would master my information and I never dared to sell it."

　　He told reporters that he learned that there are three ways at present. One is to go to the official mobile phone store, recycle old mobile phones and buy new ones by exchanging old ones for new ones. "This is safer and more secure." Secondly, some online electronic product recycling platforms will provide consumers with a recycling price as long as the user inputs the model, year and configuration. In addition, even through the offline mobile phone sales point, the recycling price may be higher, "but I am not sure if it is safe." Mr. Wu said that after thinking and thinking, he decided to leave his mobile phone idle at home and leave it to the elderly at home.

　　Regular website recycling only dares to sell non-intelligent machines.

　　"There is a mobile phone at home four or five years ago. It is a waste at home, and it won’t change much if you go out to sell it. I found that a shopping website also provided mobile phone recycling service, so I made an evaluation of my mobile phone online and found that it was still worth more than 400 yuan, so I decisively sold my old mobile phone online. " Mr. Zhang, a citizen, said that the process of selling mobile phones is relatively simple. Submit an application online, and then someone will come to collect it. Mr. Zhang introduced that during the recycling process, the staff were more serious and carefully tested the mobile phone.

　　"However, what I got after selling my mobile phone was not cash, but recharged to the personal account of this shopping website." Nevertheless, he still thinks it’s more cost-effective. First, the price of mobile phones is satisfactory. Secondly, there are many things on this shopping website, and daily necessities can be bought. Mr. Zhang said that if it is an informal website, he really dare not sell the scrapped mobile phone. "If it is a smart machine used now, with so many things bound, I dare not sell it."

　　Investigating mobile phone recyclers cannot guarantee data security.

　　In Muxiyuan mobile phone recycling street, the reporter walked into a shop and handed his Apple mobile phone to the recycler. After a simple evaluation and bargaining, the young man took the mobile phone to the shop to ask for the price. "I just deleted information, phone calls, photos and software, will it be restored?" Facing the reporter’s question, the young man looked very puzzled. "I don’t understand what you said." Without looking up, the young man entered the store with his mobile phone. After a while, the shop owner came out with a mobile phone to bargain with the reporter. Faced with a reporter’s question about whether the sale of mobile phones after information deletion can guarantee the security of personal information, the store frankly said that "there is no guarantee". "We are only responsible for recycling, but in the end, it is hard to say whether the mobile phone is resold or disassembled. If the whole machine is sold, it is possible that the information deleted inside will be restored. "

　　The boss told reporters that if you want personal information not to be restored, you can choose to disassemble and sell your mobile phone. "If you sell your mobile phone into parts, you certainly don’t have to worry about information leakage. No one has the leisure time to spell the machine and restore the data. However, in this way, the price you can get will be much lower. See how you choose. " Not only that, mobile phones are sold on some mobile phone recycling apps, and the staff also clearly stated that they can’t help completely delete the information in the mobile phone, so they can only delete it by the customers themselves.

　　The deleted data can be recovered by computer software.

　　Can a mobile phone with deleted information really be restored? With questions, the Beijing Morning Post reporter visited a number of shops involved in mobile phone business. Most merchants said that the data recovery business mainly exists in computers, and the recovery of mobile phone information can only be carried out on external memory cards, but the internal storage of mobile phones is difficult to recover. In terms of the price of recovering deleted data, depending on the different storage devices and whether the deleted information is repeatedly overwritten, it ranges from 80 yuan to more than 1,000 yuan, while the recovery time ranges from two hours to as much as one week.

　　Mr. Wang, the owner of the merchant, told the Beijing Morning Post that he had been in business for more than five years. There were not many users who recovered mobile phone information two years ago, but there were more and more users in the past year. "With the improvement of technology now, with some software, the deleted information can be recovered quickly. The threshold for doing this business is getting lower and lower, and there are more and more people. "

　　Subsequently, in a mobile phone recycling shop, the reporter took two photos with his mobile phone and deleted them. The staff connected the recovery software from the computer, and the photos immediately appeared and were saved on the computer. The staff said that the current recovery of mobile phones is mainly aimed at the text content and files of mobile phones, and it is more difficult to recover like voice. If the mobile phone is damaged, it is difficult to recover the data so easily. "Mobile phone data storage is mainly divided into two categories: built-in memory and external memory card," the staff introduced. "When deleting information on the mobile phone manually, it only changes the control structure of the data so that it can be overwritten. Therefore, most personal information of mobile phones that have not been restored to factory settings can be restored by software. However, some people have restored the factory settings, and there are still data stolen. "

　　For the data leakage caused by the built-in storage, this staff member thinks that most of the backup information and network accounts associated with it are lost. Take Apple’s mobile phone as an example. Many users only restore their mobile phones to factory settings, but forget to delete the backups of computers and iCloud.

　　Most people who sell old mobile phones forget to delete private information.

　　Zhongguancun’s army of collecting and selling second-hand mobile phones is an old Jianghu. He has been doing business in Zhongguancun for nearly ten years, and he has handled countless second-hand mobile phones. Recently, he met many people who sold their mobile phones for a few days and then returned to ask him to delete private information. He said that with the increasing emphasis on personal privacy, smart phones are bound to personal information such as bank cards, and when selling second-hand mobile phones, everyone’s concerns are increasing. "I received a mobile phone at the beginning of the year. The seller came to see me twice after selling the mobile phone. " He recalled that the lady took an Apple mobile phone to sell, and at that time, he specially reminded that important information must be deleted. After simply deleting it, she collected the money and left. A few days later, she returned to him, hoping to delete the phone number in her mobile phone. Later, about a week later, the lady came again, hoping to delete WeChat, Weibo, Alipay and so on. "The mobile phones are all sold, and they can’t be deleted. I told her, don’t worry, the second-hand smartphones we collected must be brushed before they are sold. As long as the factory settings are restored, other information will be deleted. "

　　Dajun said that since 2011, after all kinds of smart phones have appeared in an overwhelming way and the number of second-hand mobile phones has surged, he and his colleagues will remind mobile phone owners to delete important information in time before collecting their mobile phones. However, some people simply delete messages, photos and other information, and then get it back and ask for deletion until they react. "Many times, we will brush the phone and restore the factory settings before selling it, but some mobile phone experts can still restore the information."

　　The problem software encryption function master still breaks the work in front of him.

　　According to Xu Xiang, a professional who specializes in mobile phone software development, "The disclosure of privacy usually occurs after the mobile phone is stolen. The other party can easily unlock the power-on password with cracking software, then invade the original registered email address of the mobile phone through virus software, check the privacy in the mobile phone, and even unlock and modify the password of iCloud to further obtain user information. " Xu Xiang said that if the other party is malicious, at this time, the information on this mobile phone has almost been completely made public in front of the other party.

　　"In this case, the risk of economic loss is relatively high, and a friend of mine has encountered this unfortunate situation." He said that after his friend lost his mobile phone, the balance of Alipay was quickly transferred away. "However, in view of this situation, some software developers are now strengthening protective measures, and every software is improving its encryption ability." But even so, experts can successfully obtain the information on the hard disk of the mobile phone by cracking the system password. "

　　Ignoring information security is more dangerous than losing a mobile phone.

　　In this regard, Liu Yang, a mobile phone security expert, said that, in their view, this mobile phone exchange may be more dangerous in Bidiu. Because many people also know that personal privacy may be revealed after the mobile phone is lost. Once the mobile phone is lost, citizens often immediately reissue their mobile phone cards and modify various payment passwords. However, if the mobile phone is sold, users often ignore the risk of revealing privacy when changing the mobile phone.

　　He said that people change their mobile phones very quickly in China. According to a survey, 58.6% of mobile phone users will change their mobile phones within one year, but only 8.4% will use the same mobile phone for more than two years. Often when dealing with old mobile phones, 40% users will delete the software information, and more than 50% users will restore the factory settings.

　　In fact, the safest way at present is to restore the factory settings, but this seemingly safest way can not completely delete the mobile phone data. Liu Yang introduced that in theory, as long as the information on the mobile phone is not covered, the deleted mobile phone can actually be restored. Even if you use the function of restoring factory settings that comes with your mobile phone, it is impossible to completely delete all the information. The information that may be leaked includes private photos, short messages, WeChat chat records, audio recordings, videos and so on.

　　Lack of guidance for the development of industries with incomplete recycling system

　　Liu Yang believes that at present, the recycling industry of used mobile phones has broad development prospects, but it still faces problems such as imperfect recycling network system, imperfect industry policy standard system and insufficient comprehensive recycling capacity. For example, at present, there are no special regulations or management methods for the management of the waste mobile phone recycling market, the market development is irregular and chaotic, and the number of formal recycling enterprises is scarce, which makes the construction of the waste mobile phone recycling system in China insufficient. Another example is the lack of industry standards or specifications for recycling used mobile phones, information destruction, maintenance and component reuse, and the lack of guidance for the development of the whole industry. Although there are some practices that are environmentally friendly or have high resource utilization efficiency, the overall level is not high.

　　In this regard, Liu Yang made several specific suggestions: we can encourage the development of large-scale, professional and innovative recycling enterprises through means such as finance, taxation and market access; Further improve the extended producer responsibility system, incorporate production enterprises into the construction of recycling system, and encourage production enterprises to use existing sales and maintenance channels to build their own, jointly build or entrust a professional third party to build a recycling network system. In addition, a sound industry standard system should be established. Strengthen government supervision, issue corresponding technical specifications, guidelines, industry standards or certifications for all aspects involved in the recycling industry of used mobile phones, such as classification, identification, sorting, information destruction, maintenance, disassembly, component reuse, material utilization, and extraction of rare and precious metals, manage the whole recycling process of used mobile phones, encourage and guide standardized and professional used mobile phone recycling enterprises to become market players, and scientifically carry out environmentally sound treatment and efficient resource utilization of used mobile phones.

　　It is suggested to set the power-on password to unbind the online payment system.

　　Xu Xiang said that how to avoid risks as much as possible can give some suggestions to citizens who want to sell mobile phones. He said that under normal circumstances, to sell your own mobile phone, you need to remember that you should delete all personal information and unbind it before selling it. For example, online payment involved in mobile phones must be unbound. In addition, when the mobile phone number is not used, it must also be unbound in the software, because the communication operator cannot unbind it alone. "If the mobile phone number is not unbound, the purchaser can use the mobile phone number verification function to access the QQ and WeChat of the former user, including some financial accounts".

　　In addition, in order to avoid privacy risks, citizens using Android system should also set the power-on password on their mobile phones, and citizens using Apple system should set an iCloud security lock while setting the power-on password. In this way, even if the mobile phone is stolen, whether it is Android or Apple, the personal information on the mobile phone can be erased remotely. If someone wants to open the iCloud lock on Apple, they must bring the invoice, ID card and warranty card to the customer center to unlock it. "In a word, before reselling the mobile phone, empty and smash all the information; If the mobile phone is stolen, change the relevant bank password immediately, don’t trust the so-called official verification message, and don’t click on any website links with unknown sources. "

　　Technical problems need to be solved in environmental protection recycling of mobile phones

　　In view of the technical problems in the recycling of second-hand mobile phones, Professor Wang, majoring in communication engineering at Beijing University of Technology, suggested that the research and development of comprehensive recycling technology for used mobile phones should be further promoted and the processing capacity should be reasonably improved. "From the policy point of view, we should encourage the research and development and industrialization of the technology of sorting, dismantling and deep processing of used mobile phones, and strive to improve the professional processing capacity of used mobile phones in China. On the other hand, the industry should also be rationally planned to avoid overcapacity and vicious competition caused by enterprises. " He said, "In addition to increasing efforts in the disposal of used mobile phones, government departments should also pay attention to the improvement of efficiency in the recycling process, because some mobile phone users don’t know where to dispose of them even if they know they want to dispose of them. After all, their value is not high, so they should set up more facilities such as recycling bins, which can easily collect used mobile phones."

　　He said, "It is necessary to set a certain threshold for mobile phone recycling manufacturers to ensure that mobile phone recycling manufacturers with recycling strength enter this industry. The purpose of recycling mobile phones is to avoid environmental pollution and save resources. At the same time, it is necessary to create a consumer group with a sense of social responsibility, which is also the renewal and revolution of consumption concepts. The second is to encourage the recycling of mobile phone recycling manufacturers and provide corresponding preferential policies. "

　　■ Reporter’s Notes

　　Recycling mobile phones is safe and can’t run naked.

　　In September, the new Apple 8 mobile phone will be launched soon, and some "fruit powders" are estimated to start changing machines again. With the upgrading of mobile phones faster and faster, it’s really distressing that there are not a few old mobile phones that have been replaced at home, all of which were bought at the beginning with a lot of money.

　　However, you must be careful about selling your old mobile phone. The bank card bound to the mobile phone is unlocked, and the money in the card is transferred one by one. As this kind of news becomes more and more common, the public is more and more vigilant about the mobile phone. With the mobile phone around, the money inside may be stolen, not to mention selling it to strangers. During the interview, the reporter found that it is really simple for professionals to turn over the personal information you once left in your mobile phone. This is a meeting with a mobile phone security expert. If you meet a criminal professional, your personal information will become a stepping stone for them to covet property in minutes. Even if it is small, the disclosure of private information, such as address book, chat records, life pictures, private files and online preferences, will surely cause great trouble to the owner.

　　Nowadays, the mobile phone is no longer a simple communication tool ten years ago, but it integrates more and more functions such as social interaction, office work, payment, business consumption, etc., and it also carries almost the most important private information in people’s daily life, which involves property, emotion or work, and can’t stand it if it is leaked. Mobile phone has become the key to personal secret life. Do you dare to give this key to strangers?

　　However, the "key" is quite expensive after all, and being idle at home is a waste of social resources. For the reuse of mobile phones, there are no specific rules and regulations to be found so far, and the market is growing wildly. It seems that it is not enough to rely solely on the non-professional knowledge mastered by citizens to ensure the information security in mobile phones. Once the mobile phone is sold, personal information that has not been deleted or can be restored is equivalent to naked running. Then the loss that citizens will face far exceeds the three melons and two dates that they get for selling mobile phones.

　　In view of the trading regulations of second-hand mobile phones, the relevant departments should really give specific rules and regulations that can be observed, and even designate mobile phone recyclers with professional qualifications through open and transparent operations that conform to market rules. This can not only ensure the environmental protection and standardization of second-hand mobile phone recycling, but also ensure that citizens’ personal information can no longer run naked.

According to a number of foreign media reports, on February 26th, the German F-124 "Saxony" class frigate "Hessen", which was on a combat escort mission in the Red Sea, fired two "Standard-2" (SM-2) air defense missiles at a target that failed to confirm its identity and was judged as a "reconnaissance drone".

Due to technical reasons that did not disclose details, the missile failed and crashed into the sea.

F-124 frigate launches SM-2 missile.

Afterwards, it was proved that the targeted drone was an American MQ-9 "Death" drone that was carrying out a strike mission against Houthi armed targets nearby. The series of related news was confirmed by German Defense Ministry spokesman Michael Steinfler on February 28th.

However, the spokesman stressed that "Hesse" had carried out a complete identification process before firing, including radio response, and asked the allies whether there were drones performing tasks in the airspace.

MQ-9 UAV

In addition, the failure of two SM-2 missiles has also caused waves in Germany.

Lack of air defense equipment in Germany

A spokesman for the German Federal Parliament’s national defense policy said, "We have only now learned according to the requirements that some ammunition of the frigate Hessen can no longer be purchased because it no longer has the corresponding industrial capacity. When the stocks are exhausted, the German navy can no longer replenish them and must withdraw the frigates. " In addition, he also accused the current German government of concealing the truth from the opposition party, which led to the parliament’s unwitting decision to send frigates to participate in escort operations.

The F-124 frigate takes air defense as its main task, and is equipped with advanced multi-function radar and various air defense weapons, including SM-2 Block IIIA, Evolution Sea Sparrow (ESSM) and RIM-116. SM-2 BlockIIIA suffered the ammunition inventory crisis. According to the disclosure of information about this accidental attack by the German Ministry of Defence, the ammunition has been discontinued.

SM-2 series missiles were designed earlier. SM-2 Block1 was developed in 1970s, and its production line was closed in 2013 due to lack of orders.

After the Crimean incident in 2014, the global demand for SM-2 soared. Raytheon restarted its production line in 2017 to meet the demand of more than 280 SM-2 BlockIIIA/B in the Netherlands, Japan, Australia, South Korea and other countries, and announced that the production line will be maintained until 2035. In 2021, Chile made a purchase demand for SM-2 BlockIIIA to the United States, but the quantity was very small.

At present, the latest model of SM-2 series is SM-2 BlockIIIC, which is in the initial production stage of low speed. The missile has undergone a major technical upgrade and completely changed its guidance system: SM-2 BlockIIIA uses inertial navigation, radio command correction and semi-active radar composite guidance; SM-2 BlockIIIB replaces the seeker with the dual-mode system of infrared imaging and semi-active radar on the basis of Type A; SM-2 BlockIIIC is replaced by an active radar guided seeker, which comes from the "Standard -6" extended range active missile (SM-6 ERAM).

Although SM-2 BlockIIIC has been significantly enhanced in performance, it can effectively fight against high-mobility and high-agility targets and has the ability to attack targets outside the radar detection range of warships; However, the change of guidance mode and other improvements make it incompatible with the mission management and fire control system of the existing F-124 frigate.

This also means that once the existing SM-2 BlockIIIA runs out of stocks, Germany not only needs to order SM-2 BlockIIIC missiles with a long production cycle from the United States, but also needs to carry out targeted shipboard equipment improvement and certification tests for F-124 frigates. The time required for this process may be calculated in years.

Predicament of friend-or-foe identification in UAV era

Compared with the missile inventory crisis, which mainly stems from Germany’s own political struggle and management system problems, the wartime friend-or-foe identification problem once again displayed in this accidental attack is a dilemma that all countries are facing. Especially in the era of drones, this problem is becoming more and more difficult.

Friend or foe identification transponder

From a purely technical point of view, many countries have developed a large number of IFF technologies, including cooperative and uncooperative. When the two sides interact and cooperate, they can complete the identification by means of wireless communication through the principle of "inquiry/reply"; When the target is in a non-cooperative state, the inquirer will summarize and fuse all the collected target information (radar echo signal, infrared radiation, acoustic signal, GPS information) and implement compulsory identification.

In the ideal technical test environment, it is possible to realize fast and accurate identification of friend or foe by relying on the complementary combination of these two means. However, in the actual combat environment, many factors, such as political intervention, the setting of rules of engagement, and the management system of military tasks, may completely lead to the unreliability of the existing methods of identifying the enemy or ourselves. The incident in which a German frigate accidentally attacked an American drone is a typical example.

Failure reasons of collaborative identification:

For some reason not publicly disclosed by the US, the targeted MQ-9 failed to turn on the IFF transponder, or the related equipment failed, and the German frigate recognized it as a non-friendly target without an effective response.

Failure reasons of non-cooperative identification level:

Due to the differences of interests between different countries and departments, Europe and the United States have several military operations in the Red Sea and the surrounding areas of Yemen, which are not subordinate to each other and lack a unified command and coordination structure. Due to the confidentiality requirements of military operations, it is very common for different units to be unaware of the existence of the other side, even in the army of the same country.

The Hessian frigate participated in the "Aspad" escort operation led by the European Union, while the escort mission of the US military was the earlier "Guardian of Prosperity" operation. The mistakenly attacked MQ-9 is not affiliated with the "Prosperity Guardian", but another US military operation whose name is unknown at present. The US military units participating in the "Prosperity Guardian" operation are unaware of the existence of the MQ-9 drone.

This led to the "Hesse" frigate, although it initiated consultation with the American unit responsible for the "Guardian of Prosperity", but it got the wrong answer. In the airspace where the target signal is located, the real situation is only that "there is no aircraft participating in the prosperity guardian operation", not "there is no aircraft of the US military".

The 40-kilogram unmanned aerial vehicle (UAV) appeared on the battlefield in Ukraine, with a unit price of up to $15,000. It is not worth the loss to carry the traditional IFF transponder.

Compared with purely technical problems, these non-technical factors often make it more difficult to identify the friend or foe. Especially from the actual combat environment such as Ukraine and Yemen in recent years, the identification of friend or foe of drones will become more and more troublesome. The popularity of small and medium-sized UAVs and the extensive participation of civilian UAVs in military operations inevitably bring more problems, such as the following:

01For reasons such as economy and confidentiality risks, a large number of UAVs participating in the war are not equipped with IFF equipment at all.

02At the same time, the number of units operating drones on the battlefield is unprecedented, and the task information between them is not interoperable.

03A large number of unmanned aerial vehicles (especially multi-rotor aircraft) are highly similar in design, and a large number of key features are highly similar from appearance shape to acoustic signals, lacking effective means of distinction; Or both sides are equipped with a large number of equipment at the same time (more common in civilian models), and it is meaningless to distinguish models.

Undoubtedly, drones will further play a more important role in the future battlefield; How to deal with the corresponding friend or foe identification problem will be an extremely critical research topic.
