Pinterest, which has 100 million monthly active users, is increasingly relying on machine learning to help uncover new internet insights.

Users around the world visit Pinterest to explore, save, and share photos and articles. Help users find content they love, and users will naturally be retained: 30% of interactions on Pinterest and 25% of Pinterest internal purchases come from Pinterest-recommended content. To recommend the right content, Pinterest uses state-of-the-art, data-driven technology and conducts a lot of experimentation.

So how does Pinterest use machine learning?

Mohammad Shahangian, lead discovery science engineer at Pinterest, said: "My main job is to find a way to solve the content discovery problem. We experiment with very small changes to the algorithm, and every attempt has an improvement or a downside."

Exclusive advantage: based on interest

In fact, this is not unrelated to the characteristics of Pinterset: one of its strengths is that Pinterset is a community built around users’ interests, and users will sort the products, articles, and images they find on the Internet by interest.This means that instead of guessing a user’s interests by clicking patterns or time spent on a page, as other social networking sites do, Pinterest can directly use algorithms to measure the relationship between 75 billion entries in its database that are likely to be grouped under the same interest.

"Many companies try to derive user interest from inputs or signals," says Mr. Shahangian. "But on Pinterest, users clearly signal what they are interested in."

Users who visit Pinterest continue to add to the social landscape of users, collected items, and favorite boards. This data allows Pinterest to provide more accurate content for user homepage feeds, search results, and related content recommendations. Recommendations based solely on what users care about are not ideal, and recommendations for similar content are easy to repeat.

For Mohammad Shahangian, "If you collect one kitchen sink, should we recommend more sinks or something that will make your kitchen look new?"

Constantly testing in practice

To make these decisions, Pinterest engineers experimented with a variety of machine learning algorithms. They studied how well these algorithms worked on related and unrelated items, and how they affected the active levels of real users.

Mohammad Shahangian said: "We do experiment directly on Pinterest, but a lot of times we do a lot of preparation before experimenting."

Of course, there is no way to know whether a user will like the new recommendation without conducting actual testing. "I can’t pay someone to tell me whether a user will like the new recommendation," says Mohammad Shahangian. But by studying whether the content recommended by the algorithm will be classified as an interest by real users, it is relatively reliable.

Previously, Pinterest changed the message flow on the user’s homepage from purely chronological attention to the user’s message, to an algorithm-generated message flow, which increased the user’s active level by one-fifth to one-tenth. Subsequent algorithm improvements will bring additional improvements.

"Pinterest has come a long way throughout the improvement process," says Mr. Shahangian. "Personalisation has greatly increased user engagement rates."

Improved image search function

Pinterest has also been improving image search to help users better find similar images. Pinterest engineers worked with researchers at the Vision and Research Center at the University of California, Berkeley, to develop the technology. It now uses deep learning algorithms to automatically identify objects in images. This way, users can click on those objects to find relevant items in Pinterest.

Dmitry Kislyuk, a visual search engineer at Pinterest, said: "This is not a classification algorithm to distinguish between cats and dogs. We want to find similarities between images in real time."

He says the visual search tool works well for finding home decorations and fashion items in Pinterest, and in the future Pinterest hopes to improve its auto-sorting function to better serve other search needs, such as helping users find new recipes that are similar.

Speaking about using deep learning to classify images more efficiently, Pinterest visual search engineer Andrew Zhai said: "I think our model will become more semantic and better."

While Pinterest engineers focus on perfecting object recognition and search, they also plan to develop an app that will allow smartphone users to photograph real-world objects and then get recommendations for related items on Pinterest.

"The field of deep learning, computer vision is very exciting right now," says Mr. Kislyuk. "The world is changing so fast that top technologies change every two months."

Xingyue L is equipped with Volvo engine, Changan and Haval announce brand-new SUV, and BBA recalls it.

It is expected to pre-sell Haval in April and release the official map of the new model Haval Red Rabbit.

A few days ago, Great Wall Motor officially released the official map of its brand-new model Haval Red Rabbit. It is planned that the new car will be officially opened for pre-sale in April this year. The appearance of Haval Red Rabbit adopts the brand-new aesthetic design concept of "Tide Awakening" of the Great Wall. The front grille is an iconic large-size hexagon, and the interior adopts a straight waterfall design with chrome-plated decoration. The headlights are irregular in shape, and the daytime running lights and headlights are separated. The D-pillar design of Haval Red Rabbit is more rounded, and a large suspended tail is added, giving people a visual effect of sharp style and movement. It is reported that the design of the new car is inspired by the charge posture maintained by athletes when they start to exert their strength.

The new car is positioned in a compact SUV, with a length of 4450mm and a wheelbase of 2700mm in body size, which is quite satisfactory in its class. This car is based on the global intelligent vehicle platform Lemon Platform, and it is the fourth model mass-produced by this platform. Lemon platform has the characteristics of high flexibility, high performance, high safety and light weight, which can give new cars good advantages in intelligence, performance, safety and space ratio.

At present, the power scheme of the new car has not been announced yet, but we predict that the new car will adopt a combination of 1.5T engine with high and low power and 7DCT wet dual-clutch gearbox. Among them, the high-power version can output the maximum power of 135Kw and the peak torque of 270Nm.

Recently, Geely Automobile announced the latest news of Xingyue L. The new car will come standard with Volvo Drive-E 2.0TD power. The maximum power of the 2.0T engine is 175kW (about 238 HP) and the peak torque is 350 Nm. It is worth mentioning that the Star Yue L is a brand-new SUV based on the CMA super matrix. Compared with the Star Yue on sale, the "L" of the Star Yue L has the meanings of Larger, luxurious and subversive.

In terms of design, the straight waterfall net of Xingyue L is very atmospheric, and the "meter-level full screen" of the interior is also amazing, giving people a refreshing feeling. Although the car is positioned as a compact SUV, in terms of body size, it has reached the standards of many medium-sized SUVs, even much larger than the Jetway X70 PLUS, Buick Angkewei, Tiguan L, Chevrolet Explorer and other models positioned as medium-sized SUVs.

Changan Automobile’s new car release frequency is really fierce in recent two years. Not long ago, Changan Automobile officially released a set of new car preview maps, but the car has strict camouflage. It is reported that the new car belongs to CS series. But judging from the lines of the car body, it is likely to be the third car in the UNI series.

The new car adopts a sharp headlight shape, and the body camouflage sticker is printed with all kinds of hot words in the mouth of young people. Obviously, this car user group will also target young people; The lines on the side of the car body are sharp, especially the layering of the two waistlines on the D-pillar is very strong; In terms of power, it is expected that it will most likely be equipped with Changan Blue Whale NE 1.5T L4 engine and 7-speed dual-clutch gearbox. Other aspects have not released more information for the time being, and we will continue to pay attention.

Mercedes-Benz (China) Automobile Sales Co., Ltd. and Beijing Benz Automobile Co., Ltd. filed a recall plan with the State Administration of Market Supervision according to the requirements of the Regulations on the Management of Defective Automobile Product Recall and the Implementation Measures of the Regulations on the Management of Defective Automobile Product Recall. The recall involved some imported and domestic C-class (platform 205) vehicles, totaling 125,568 vehicles. The reason for the recall is that if the vehicle is idling for a long time under the unfavorable heat dissipation environment, the heat generated by the rectifier bridge diode may not be dissipated in time, and individual diodes may also cause short-circuit failure due to exceeding the maximum working temperature, which leads to the temperature rise of the alternator stator coil, which cannot rule out the fire risk and has potential safety hazards.

Therefore, Mercedes-Benz (China) Automobile Sales Co., Ltd. and Beijing Benz Automobile Co., Ltd. will upgrade the engine control unit software for vehicles within the scope of recall through authorized dealers to eliminate potential safety hazards.

Coincidentally, at the time of Mercedes-Benz recall, Audi also announced the recall of domestic A6L, Audi Q3, imported Audi A6 Avant 2.0T and imported Audi A7. The specific production time of vehicles is some domestic A6L 2.0T vehicles produced from April 25th, 2018 to November 24th, 2020, totaling 118,074 vehicles. And some imported A6 Avant 2.0T and A7 2.0T vehicles produced from October 14th, 2019 to November 13th, 2020, totaling 6,724 vehicles.

The reason for the recall is that under certain working conditions when the engine is idling, the imperfect learning function of the camshaft adjuster driving algorithm in the engine control unit may lead to the deviation of the results, which may cause the camshaft not to be adjusted to the correct position, which may lead to the unstable operation of the engine, and in extreme cases, the engine may stop running, posing a safety hazard. FAW-Volkswagen Automobile Co., Ltd. will entrust Audi authorized dealers to upgrade the engine control unit software for vehicles within the recall range free of charge to eliminate potential safety hazards. There are also two Audi Q3′ s recalled because the pulley in the steering gear may have dimensional deviation, which may lead to the incorrect installation of the circlip during the assembly process.

As if it was agreed, BMW Brilliance Automobile Co., Ltd. also filed a recall plan with the State Administration of Market Supervision. A total of 8,114 X3 and iX3 vehicles with production dates from December 29th, 2020 to January 25th, 2021 were recalled.

The reason is that a rocker switch in the automatic seat belt retractor in the middle of the rear row may be positioned incorrectly due to the assembly error of the vehicle in the production process of the supplier. In case of failure, the inductive locking sensor may not work normally in the seat belt retractor, thus causing the passengers to be unable to be fixed on the seat during emergency braking. BMW Brilliance Automobile Co., Ltd. will check the rear middle seat belt for the affected vehicles free of charge and replace the rear middle seat belt if necessary. I have to say that these three brands deliberately chose to announce the recall plan at the same time. It is really a coup to distract consumers’ attention!

"Three Threads" in front of Xiaomi Automobile | Titanium Garage

Xiaomi car has not yet entered the market, and Lei Jun has begun to be anxious.

Recently, Lei Jun, chairman of Xiaomi Group, said in an interview with CCTV that he was worried that Xiaomi’s car would not catch fire as soon as it came up, and that everyone would buy it. "It was all kinds of anxious emotions."

In fact, since the day when Officer Lei announced the construction of the car, Xiaomi Automobile has always brought its own traffic attributes, but this is a "double-edged sword"-

  • On the one hand, Xiaomi automobile has gained great attention from the public without blowing off dust. Even though the government has not disclosed the progress of Xiaomi’s car-making, new news has been constantly revealed and even leaked many times.
  • On the other hand, the public’s high expectation of Xiaomi car is undoubtedly the pressure of Xiaomi to build a car. The public’s hung appetite needs to be fed to avoid traffic.

Although Xiaomi automobile has not entered the market, it has attracted much attention. In the face of huge traffic dividends, Xiaomi’s approach is not to increase exposure, but to maintain a "mystery."

It is reported that Xiaomi will launch a car-related event on December 28, but Xiaomi has not officially announced it. This kind of publicity rhythm is rare and abnormal in the industry.

But in any case, the debut of Xiaomi’s first model has entered the countdown, and the first shot of Xiaomi’s car will eventually be revealed. However, before Xiaomi Automobile officially entered the market, there were many difficulties ahead.

"Net red face" get together, can Xiaomi SU7 break through?

In November this year, Xiaomi Automobile landed in the new batch of new car declaration catalogue of the Ministry of Industry and Information Technology, and the first product of Xiaomi Automobile was also made public for the first time.

It can be seen that the appearance of Xiaomi’s first car is similar to that of Porsche Taycan, and it is similar to the models of Zhijie S7, Extreme Krypton 007, Extreme ROBO-02 and Star Road Interstellar ES.

Comparison between Xiaomi SU7 and competing models

According to the specific parameter information, the length, width and height of the first car "SU7" of Xiaomi are 4997mm/1963mm/1455mm, and the wheelbase is 3000mm, which is longer than the potential competitors such as Model 3, Tucki P7, Zhijie S7, and Extreme Krypton 007.

According to external sources, Xiaomi’s first car may be divided into three versions, namely, the regular version, the Pro version and the MAX version, and the price may be in the range of 190,000-300,000.

We should know that the B-class sedan market of 200,000-300,000 is the most competitive position at present. In this market segment, there are old faces such as BYD Han EV, Tesla Model 3 and Tucki P7, as well as the newly listed Zhijie S7, Yinhe E8 and Extreme Krypton 007.

Judging from the performance of the players on the field, BYD Han EV and Tesla Model 3 have gained a firm foothold, and sold 12,841 vehicles and 23,999 vehicles respectively in November, making them the two major peaks.

Among the new entrants, Zhijie S7 is an ecological product of HarmonyOS Zhixing, which uses Huawei’s latest technologies in chassis, safety, cockpit and intelligent driving, and is equipped with Huawei’s intelligent driving solution ADS 2.0;; Geely Group sits behind Krypton 007 and Galaxy E8.

In other words, Xiaomi SU7 is about to enter a battlefield surrounded by enemies.

According to the published application information, we can only know that Xiaomi SU7 will use lithium iron phosphate battery, and the supplier is Xiangyang Fudi Battery Co., Ltd. under BYD. The peak power of the driving motor is 220kW, and the supplier is United Automotive Electronics Co., Ltd.. In addition, the vehicle will provide optional items including side fender lettering, ETC, exterior rearview mirror, skylight glass, laser radar and so on.

Although more specific configuration information about Xiaomi car has not been made public, from the perspective of Xiaomi’s genes, its accumulation on mobile phone terminals makes it potentially competitive in smart cockpit.

In October this year, Xiaomi released "澎湃 OS" to open up the ecology of people and cars. Through the opening of the bottom layer of cross-scenario and cross-ecological software, Xiaomi Automobile got the card of "cross-terminal and cross-scenario experience", and the car companies in the industry currently have this kind of simultaneous layout of mobile phones and car terminals. There are three manufacturers: Geely, Weilai and Huawei.

Whether Xiaomi can release the advantages of drivers’ interconnection to form competitiveness after entering the automobile market is unknown, but the game between Xiaomi SU7 and Zhijie S7, Yinhe E8 and other products in drivers’ interconnection is actually that Xiaomi is once again facing Huawei, Meizu and other old rivals.

In addition to the competitiveness of product configuration, the most uncertain thing about Xiaomi Automobile at present is the pricing problem-the pricing is too high to gain market recognition and affect sales; If the price is too low, the standard line of brand impression will be set, and at the same time, factors such as profit rate need to be considered. At the same time, the intensified price war also makes the pricing of Xiaomi Automobile more difficult.

Faced with the layers of new and old players, Xiaomi SU7 has officially started the breakout campaign since it entered the arena.

How can the latecomers make up for the battle of opening the city with wisdom?

"The goal of Xiaomi Automobile is to enter the first camp of the autonomous driving industry in 2024", which is the swear words released by Lei Jun in his annual speech in August 2022.

In Lei Jun’s view, autonomous driving is the key to the success of smart electric vehicles. Xiaomi will also choose autonomous driving as the breakthrough direction of smart electric vehicles and unswervingly follow the path of full-stack self-research.

Before this path was made public, Lei Jun began to set up an autonomous driving R&D team with L4 as the goal as early as 2021, and integrated the artificial intelligence laboratory, Xiaoai team, mobile phone camera department and other departments of the group to provide cooperation for intelligent driving development.

According to the information revealed by Lei Jun in his speech, the first phase of Xiaomi Auto’s self-driving project invested 3.3 billion yuan in research and development. The team covers sensors, chips, sensing control algorithms, simulation technology, high-precision maps, high-precision positioning, tool chains, training capabilities and other automatic driving full-stack technical talents.

Later, external news pointed out that the person in charge of Xiaomi’s auto-driving was Ye Hangjun, a veteran of Xiaomi. He joined Xiaomi in 2012, and was first responsible for cloud technology, then for the artificial intelligence department, and then switched to the auto-driving industry.

According to Lei Jun’s interview with CCTV, Xiaomi invested 3,400 engineers in the first car and invested more than 10 billion in research and development.

Smart driving industrial chain enterprises invested by Xiaomi

In order to quickly make up lessons in autonomous driving, Xiaomi invested in a large number of upstream and downstream companies in the industrial chain before the layout of autonomous driving, including black sesame intelligence, an automobile chip manufacturer; Automatic driving manufacturers Momenta, Zhixing, Zongmu Technology, etc.; Laser radar manufacturer Hesai Technology, etc., and in 2021, it wholly acquired the autopilot company DeepMotion Tech Limited, which has a layout in the fields of high-precision positioning, high-precision maps and 3D scene reconstruction.

However, the demonstration of Xiaomi’s auto-driving technical ability still stayed in August, 2022. At that time, the video data showed that Xiaomi’s auto-driving system could realize the functions of calling vehicles with one button, automatically entering the ramp, actively changing lanes to overtake, making unprotected turn/U-turn, automatically bypassing temporarily stopped vehicles/accident vehicles/roundabout, and autonomous parking service. After the vehicle is parked and parked, it can also be automatically charged by the mechanical arm.

After more than a year of R&D iteration, it is still unknown whether these capabilities can be mass-produced. However, the domestic smart car market has ushered in an unprecedented development period, and the competition of car companies in intelligent driving has moved from high-speed NOA to urban NOA, and they are competing to be involved in the battle of opening the city NOA.

Some manufacturers have experienced the game of choosing high-precision maps, and the algorithm has also been iterated, reconstructed and revised, while Xiaomi Automobile has always been in a silent state.

Intelligent driving ability is on the one hand, and more importantly, engineering landing and verification. It needs a certain amount of training and testing on the open road. Even if Xiaomi’s first model has the ability of NOA in the city as soon as it comes on the stage, it still needs to catch up with the players who are relatively the first to lay out in the open speed.

Liu Yilin, Senior Director of Autopilot Products in Xpeng Motors, recently publicly talked about the importance of real vehicle data to the verification of urban assisted driving test. He mentioned that "it is risky to rely on shadow mode on a large scale in the cold start stage, because there is no real vehicle data, and whether the shadow mode itself is reliable or not has not been verified. Only by combining the real vehicle verification+simulation mileage+shadow mode, combined with the Bad Case of a large number of production vehicles, can the functional safety be more securely guaranteed. "

According to various plans, Huawei NCA plans to be available nationwide by the end of this year, Xpeng Motors NGP plans to expand to 50 cities by the end of this year, and Weilai NOP+ will open 60,000 kilometers by the end of this year. All car companies are accelerating the landing of urban driving assistance capabilities, and all of them have a certain amount of real vehicle data running on the road.

Xiaomi Automobile, which wants to enter the first camp of the autonomous driving industry in 2024, should compress the competition in product experience, online time and the number of Kaesong into a more compact time range, so as to be able to compete with other automobile companies. This is not only a technical competition, but also a sales competition and a resource competition.

Can the trial of productivity hell stand up?

Entering the manufacturing process is the beginning of Xiaomi Automobile’s mass production.

In an interview with CCTV, Lei Jun said, "Cars are really complicated. I am particularly worried that if they don’t catch fire, everyone won’t buy them; What is more worrying is that if everyone comes to buy it, it will take a year or two to wait, and it will definitely be miserable. "In fact, it refers to the management of supply chain and factory capacity.

Screenshot of the new car declaration catalogue of the Ministry of Industry and Information Technology

It can be seen from the information of the new car declaration catalogue of the Ministry of Industry and Information Technology that the qualification subject of Xiaomi Automobile is "Beijing Automobile Group Off-road Vehicle Co., Ltd." and the production address is "No.21 Courtyard of Huanjing Road, Beijing Economic and Technological Development Zone", that is, the location of Xiaomi Automobile’s self-built factory.

Although it is still doubtful whether Xiaomi’s automobile production qualification has fully landed (according to the Regulations of the National Development and Reform Commission on Automobile Industry Investment Management in 2018 and the Regulations of the Ministry of Industry and Information Technology on New Energy Automobile Production Enterprises and Product Access Management in 2020, the new car manufacturing company needs to obtain the two qualifications of the National Development and Reform Commission and the Ministry of Industry and Information Technology at the same time), it can be confirmed from the application information that Xiaomi will produce "Xiaomi SU7" in its own factory.

Xiaomi Automobile Factory has two projects, one of which covers an area of about 720,000 square meters and has an annual production capacity of 150,000 vehicles. At present, it has been completed and started to enter the trial production stage. The first product prototype has been off the assembly line and is ready for mass production. The second phase is scheduled to start in 2024 and be completed in 2025.

Lei Jun once said that the first model of Xiaomi Automobile plans to sell 100,000 vehicles in the first year and deliver 900,000 vehicles in the next three years. This means that from 2025 to 2027, Xiaomi Automobile needs to produce and sell at least 300,000 vehicles every year.

Although Xiaomi has experience in supply chain management and manufacturing in the field of mobile phones, it is still a novice in the automobile industry. The automobile industry, which is known as the "pearl in the crown of human manufacturing", not only has a long supply chain, but also has a difficult capacity management. Even the head car companies such as Tesla and BYD can’t escape the torture of "capacity hell".

This year’s "Biography of Musk" recorded the whole process of Tesla Model 3′ s experience of productivity hell. Even the Tesla factory with high automation degree will be stuck in the production line because of a slight mistake or a certain part. An unimpeded production line needs more time to run in and accumulate a lot of invisible knowledge in management and technology besides the initial capital investment and the design of the production line.

The difficulty of capacity management lies in supply chain management. A supply chain manufacturer once told Titanium Media App that Xiaomi’s early negotiations with the supply chain gave an expectation of "100,000 in the first year". Usually, suppliers will arrange production according to demand, but when the production capacity is tight, some suppliers will tilt resources based on strategic considerations, which will undoubtedly increase the difficulty of supply management of car companies.

This year, Tucki G6 Max had affected the delivery speed because the laser radar supplier was not prepared enough; In the delivery of Krypton 001, the production capacity of Krypton 001 was slow due to insufficient suspended supply.

Xiaomi Automobile Factory only entered the trial production stage in September this year, producing about 50 prototype cars every week. For Xiaomi automobile, which has not experienced actual production, supply chain management and capacity management are all thresholds that it has to cross.

There is no "newcomer protection period" in the automobile market.

Xiaomi once entered the mobile phone market as a subversive, but in the matter of building a car, Xiaomi is actually no different from many new force car makers. There may be no shortage of pits to step on and classes to make up.

Different from the new car companies that have already entered the market, Xiaomi needs to face the cruel competition in the automobile industry when it enters the market. It is a consensus in the industry that the new energy vehicle market enters the knockout stage. Whether it is a three-year boundary or a five-year competition period, the first shot is particularly important for Xiaomi Automobile, which arrived late.

After all, in the face of fierce market competition, there is no so-called newcomer protection period.

Computer seal engraving is easy to counterfeit. Hand seal engraving is on the verge of extinction (Figure)


Computer engraving is popular, and the business of seal carvers is slow.


  This newspaper (reporter Shi Shanwei photographed Qin Yang) only needs a carving knife to put the names, flowers, birds, insects and fish into the square inch. Xiang Songqiu, who lives in Laoxiguan, Guangzhou, has been in business for 50 years for three generations. Although he is famous far and near, he can’t get a single business in January. Computer engraving is all over the street, and a seal can be done in one minute, which is convenient and at the same time, it also makes the fake official seal flood and hard to prevent. Manual seal cutting is unrepeatable, but few people care about it, and this traditional craft is facing extinction.


  Fifty years into the business, carving official seals to become famous.


  In Heping West Road, Liwan District, I saw a sign of "Autumn Carving" on the roadside. Walking up the narrow staircase to the second floor is Xiang Songqiu’s living room, and a wooden table in the corner is his workbench.


  Xiang Songqiu, 63, is the third generation descendant of Xiang Jia’s seal cutting, and Yin Chuang, the wooden table, was handed down by his ancestors. His uncle Xiang Xinnan was a famous stone engraver in Guangxu period of Qing Dynasty, and his father Xiang Shaonan was also a minor famous stone engraver. He worked as an artist for more than 80 years and carved seals for many celebrities and politicians. Xiang Songqiu entered the Red Seal Engraving Factory in Guangzhou on January 1, 1960, and has been in the business for 50 years.


  "Horn, ivory, jade, pear wood, boxwood, pen wood … all can be used for engraving, but different materials need different carving knives." Talking about this craft, Xiang Songqiu gushed.


  Not only is Xiang Songqiu well-known in the industry, but he has also been interviewed by many English media, and the British and German consuls in Guangzhou have also come to him to carve seals. Compared with his predecessors, he also carved the zodiac, flowers, birds, insects and fish into it when carving leisure chapters. Once a man asked all over Guangzhou to engrave his name in a painting, but his peers said that he could not engrave it. Finally, he found Master Xiang, and this seal became his masterpiece.


  After 50 years in the business, Xiang Songqiu is best at carving official seals. Before the reform and opening up, many banks, police stations and other government departments in Guangzhou appointed him to engrave the seal. "The business of engraving can also reflect the ups and downs of the economy. The 1980 s was the golden age of engraving." Xiang Songqiu recalled that at most, he took over thousands of orders to engrave the company’s official seal in a month.


  Computer engraving "encourages" fake official seal fraud


  However, in the late 1990s, computer engraving began to rise because of its low price and high speed, which quickly occupied the market. Master Xiang’s business has plummeted, and now there are so many "autumn engravings" that he can’t get a single business for a month at the worst.


  "Computer engraving is the same and easy to counterfeit." Xiang Songqiu said that the hand-carved chapter is unrepeatable, and the fake chapter can be known at a glance. Xiang Songqiu plans to cooperate with a computer engraving shop.
