"The road is getting wider and wider, but it is getting harder and harder to get into the water." On July 23rd, 2021, when Bo Huang, a citizen of Zhengzhou, passed by the wulongkou parking lot of Metro Line 5 (hereinafter referred to as wulongkou parking lot), he was so emotional when he looked at the flood continuously spewed out by the pump pipeline.

On July 20th, Zhengzhou Metro Line 5 was forced to stop by flood, and more than 500 people were trapped. At present, at least 12 people have been killed. According to the official report on the cause of the accident, on July 20th, a rare torrential rain suddenly fell in Zhengzhou, causing serious water accumulation in the wulongkou parking lot of Zhengzhou Metro Line 5 and its surrounding areas. At about 18 o’clock, the accumulated water washed out of the water retaining wall of the entrance line and entered the main line section, causing a train on Zhengzhou Metro Line 5 to stop.

What is not clear in the circular is, where did the serious accumulated water in wulongkou parking lot and its surrounding areas come from? Is there any other spillway before the flood breaks through the parking lot retaining wall? And, after the meteorological department issued a number of red warnings, why didn’t this "well-known" low-lying area respond to the plan?

According to the survey of Interface News, it is no accident that water accumulated in the parking lot and its surrounding areas in wulongkou. Ten years ago, it was a "famous" water accumulation area, and it has improved after treatment. However, before the rainstorm, tens of meters of cement cover plates were added to the open drain more than 20 meters away from the parking lot in wulongkou, which led to poor flood discharge, or was one of the reasons for the water accumulation in the subway tunnel.

"Water from three directions meets in one place"

Bo Huang felt that flooding into Metro Line 5 was not completely inevitable.

At about 17: 00 on July 20th, the accumulated water brought by the rainstorm was almost knee-deep, but Bo Huang decided to walk home from the company near the parking lot in wulongkou. He has lived in this area for nearly 40 years and is familiar with the roads and terrain here. He walked south along Lantian Road, and when he reached the first intersection, he turned into Songshan North Road.

"It’s not stagnant water. I can see the water flowing to the north (in the direction of wulongkou parking lot) with the naked eye." Bo Huang said. He walked in the direction of the incoming water, feeling that the water was getting deeper and deeper, and the resistance his body encountered was getting bigger and bigger. Although the parking lot in wulongkou is low-lying, he was somewhat surprised by the rising speed of the flood.

Less than 1000 meters from the company to the first intersection, Bo Huang walked for more than half an hour. This is an intersection inclined to the east, and the four roads radiated from it have four names due to different construction times, namely Songshan North Road facing east, wulongkou South Road facing west, Tongbai North Road facing south and Lantian Road facing north. Arriving at the crossroads, Bo Huang was surprised to find that all the accumulated water on the other three roads rushed to Lantian Road, heading north towards the parking lot in wulongkou.

Bo Huang is 1.75 meters tall. At this time, the flood has flooded his waist. He didn’t dare to wade forward and chose to return to the company. He walked back carefully along the current.

At about the same time, Wang Chao, a worker near the parking lot of Line 5, came out of the shed to see if his car was flooded. He saw that the accumulated water on the environmental protection road in front of the office area of wulongkou parking lot was flowing in the direction of Lantian Road; Not only that, the water in the northern section of Lantian Road is also flowing south. Floods from three directions flock together to the intersection of Lantian Road and Environmental Protection Road, which is the wall of wulongkou parking lot on Metro Line 5 facing the highway.

Wang Chao noticed that across the Blue Sky Road, a yellow plastic baffle was erected opposite the parking lot in wulongkou. Behind the baffle was a small river, but the flood could not cross the baffle for a while and accumulated higher and higher in this area. Wang Chao had never seen such a flood, so he ran back to the shed. Before long, he heard "a sound like a waterfall falling", which lasted for a while and became a steady sound of falling into the water.

On his way back, Bo Huang felt that the flood had a downward trend. When he walked back to the parking lot near wulongkou, he found out the reason: the wall near Lantian Road in wulongkou parking lot was washed away, and the flood fell like a dam and entered the subway parking lot dozens of meters deep.

Afterwards, Zhengzhou officially informed that on July 20th, a rare torrential rain suddenly fell in Zhengzhou, causing serious water accumulation in the wulongkou parking lot of Zhengzhou Metro Line 5 and its surrounding areas. At about 18 o’clock, the accumulated water washed out of the water retaining wall of the entrance line and entered the main line section, causing a train of Zhengzhou Metro Line 5 to stop in the section from Shakou Road Station to Beach Temple Station, and more than 500 passengers were trapped.

Zhengzhou Metro Line 5 started construction in December 2014 and was opened to traffic on May 20, 2019. This line is a ring road with 32 stations, a depot and a parking lot-wulongkou parking lot, which is the busiest line in Zhengzhou subway.

The subway parking lot mainly undertakes the work of stopping inspection and cleaning of subway trains. The train passes through the entrance and exit lines and enters the main line. This is also the route for the flood to enter the subway car tunnel. Although the parking lot in wulongkou is a ground parking lot, there are still several meters of height difference between the train parking area and the ground. On the periphery of the parking lot, there is a fence with a brick base and a steel pipe at the upper part.

According to a tender information of the parking lot published in 2017, the parking lot in wulongkou is in the shape of a knife handle, with a length of about 900m from east to west and a width of about 220 m from north to south. The total planned area of the parking lot is about 18.3 hectares, of which the subway land area is about 11.3 hectares.

At this time, Bo Huang noticed that, just opposite the wall of the washed-out parking lot of Metro Line 5, the yellow building baffle was also washed away with some gaps, but on the other side of the gap, the flood did not drain into the river smoothly, but stayed on a section of tens of meters long cover plate on the river.

He believes that the rainstorm is not the whole cause of the disaster. "The rainstorm is very heavy, but if the drainage ditch can play a role, it will not necessarily flood the subway."

Open drainage ditch becomes culvert

On July 23rd, the interface journalist came to the wulongkou parking lot of Metro Line 5. The washed-out area seemed to have opened a gap, and the fence and reinforced guardrail fell into the parking lot, with messy garbage hanging on it. Several pumps are working to drain the accumulated water to the road several meters away. The discharged water does not flow, but is deposited here and enters the underground pipeline through the filter screen. "Everyone knows that the terrain here is the lowest." Bo Huang said.

Across the Blue Sky Road, more than 20 meters away is a small river named wulongkou Minggou, which flows from south to north. Bo Huang introduced that when Lantian Road was not built, wulongkou Minggou belonged to Minghe River, and nearby villagers often built board houses to do business. Later, the blue sky road crossed the river, and a section of the river became an underground river.

The natural landform of Zhengzhou is high in the southwest and low in the northeast, with a natural gradient of 3.4‰ and a natural height difference of more than 30 meters between the west and east of the city. Wulongkou parking lot is located in the northwest of Zhengzhou, between the Second Ring Road and the Third Ring Road. Compared with the whole city, the terrain here is not low, but it is a well-known depression in wulongkou area. Standing near the washed-out wall of the subway parking lot, you can feel visually that the road surface in three directions is obviously higher than here.

The problem of water accumulation near wulongkou has a long history. As early as 2009, a person in charge of the Zhengzhou Municipal Department introduced in an official document that the accumulated water in the roads of Funiu Road and Tongbai Road was mainly discharged to wulongkou Minggou, and then discharged from the urban area through wulongkou Minggou. However, before entering wulongkou Minggou, the accumulated water in these roads had to "climb" over a high slope of 80cm before entering the river.

In July 2010, Zhengzhou City was hit by heavy rain, and a large number of roads were flooded. The citizens complained quite a lot. In this context, the Zhengzhou municipal government sorted out 62 water accumulation points in the whole city, and the responsible persons of several units subcontracted them to transform them in place within a time limit. Among the materials seen by the interface journalists, the problem of water accumulation in the Minggou area of wulongkou was "famous on the list", and the subcontracting leader was Yue Moumou, then vice chairman of Zhengzhou CPPCC.

After this reconstruction and subsequent dredging, the drainage function of wulongkou open ditch has been improved, and the problem of water accumulation in the nearby area has been alleviated to some extent. Bo Huang remembers that there was a rainstorm in Zhengzhou about three years ago. At that time, the accumulated water in the vicinity was close to the knees, but the excessive accumulated water finally flowed into the open ditch in wulongkou, causing no serious losses.

A number of nearby residents said that this small river has a history of several decades, and later the wulongkou Sewage Treatment Plant was built nearby, and the small river became a drainage river of the plant. After the construction of Lantian Road, the river flows out from under the road, and people standing on the side of the road can see the river. In case of rainstorm, excessive accumulated water directly drains into the open ditch of wulongkou over the subgrade, flows about 5 kilometers, flows into the famous Jia Luhe of Zhengzhou, and finally flows into the Huaihe River.

The interface journalist noticed that the height of the brick wall base of wulongkou parking lot is obviously higher than the entrance of wulongkou Minggou across the road. This means that when the flood reaches this area, it should normally first flood into the open ditch in wulongkou and be discharged.

A number of nearby citizens said that about a few months ago, a cement cover plate was added to the river section here, and the original open ditch became a culvert, resulting in poor drainage of excessive accumulated water. The interface journalist saw at the scene that the cover was about 8 meters wide and nearly 50 meters long, and it was made by splicing a single white reinforced concrete beam. At the gap between the two covers, a large amount of domestic garbage flowed down.

There are several excavators parked by the river. The yellow baffles have been dismantled, some have been squashed, and some mounds have been shoveled off. From the sidewalk into the upper cover, you can see the whole picture of wulongkou open ditch. The river is about ten meters wide and five or six meters deep, and there are a lot of weeds and garbage scattered on both sides. Wastewater flows out of the river under the cover plate and smells bad.

There is a precedent for poor flood discharge after the river is covered with slabs. On July 18th, 2007, Jinan was hit by a super heavy rain, and many flood discharge ditches covered with sheds were congested, resulting in poor flood discharge, which caused many losses to citizens’ lives. Later, Jinan took this opportunity to demolish some buildings with shed roofs on flood discharge ditches.

On July 23, a staff member of Shifo Sub-district Office of Zhengzhou High-tech Zone responded to the news of the interface. The open ditch in wulongkou was managed by the office. Because of the height difference between the river and Lantian Road, there was a safety hazard, so a cover plate was added to the river, which will be developed into a green belt. "After the approval of the municipal government, the (high-tech zone) management Committee." Regarding the impact of increasing the cover plate on flood discharge, she said that "this situation should have been considered."

Does the red warning work?

So, does the relevant department of Zhengzhou really consider the flood discharge risk brought by heavy rain? Are all aspects of early warning in place?

After the disaster, Zhengzhou officially announced that from 20: 00 on July 17 to 20: 00 on July 20, the rainfall during the three days was 617.1 mm. Among them, hourly precipitation and single-day precipitation have all exceeded the historical record of 60 years since Zhengzhou station was established in 1951. The average annual rainfall in Zhengzhou is 640.8mm, which is equivalent to the previous year’s rainfall in these three days. At the same time, the saying about the rainstorm "once in a hundred years" and "once in a thousand years" began to spread.

On July 21st, Chen Tao, chief forecaster of the Central Meteorological Observatory, introduced that from the perspective of atmospheric science research, it was after 1950 that China formed a rigorous meteorological record, and only then did it have a more accurate and complete scientific record of rainfall. Up to now, the whole rainfall record is about 70 years. He said that the so-called "once in a hundred years" and "once in a thousand years" is "difficult to talk about this problem" until reliable, long-term and effective rainfall records are obtained.

According to public information, on July 19th, @ Zhengzhou Meteorology released a number of information about local heavy rainfall. At 12: 28 on July 19th, Zhengzhou Meteorological Observatory released the yellow rainstorm warning signal. The approaching forecast issued at 13: 00, 14: 00, 14: 28, 16: 00, 18: 00 and 18: 13 on the same day is still yellow rainstorm warning, or yellow rainstorm warning and lightning warning.

At 19: 13 on the same day, Zhengzhou Meteorological Observatory issued the first orange rainstorm warning signal of this rainfall. At 21: 59, Zhengzhou Meteorological Observatory released the first rainstorm red warning signal of this round of rainfall. At 06: 02 on July 20th, the station released the rainstorm red warning signal again. On the same day, Zhengzhou Meteorological Observatory issued 10 red rainstorm warnings.

The rainstorm warning signal is divided into four levels: blue, yellow, orange and red. In Chinese mainland, the red rainstorm warning signal is the highest level. The corresponding defense guidelines include: the government and relevant departments should do a good job in emergency and rescue work against rainstorm according to their duties; Stop assembly, suspend classes and suspend business (except for special industries); Do a good job in the prevention and rescue of disasters such as flash floods, landslides and mudslides.

Looking back before and after the disaster, these early warnings did not play their due role. On July 23, interface journalists interviewed a number of surrounding citizens along the flood discharge channel of Changzhuang Reservoir in Zhengzhou City. Many people said that they had not received any reminders such as suspension of work, suspension of classes and evacuation before the waterlogging occurred, and many people still went to work as usual.

A person from the meteorological department introduced to the interface news that it is rare to issue nearly 10 red rainstorm warnings in one day, and the emergency management department should pay enough attention to it. However, among various government units, the meteorological department is relatively weak and is a "small department". "They listen to what we say, and they don’t listen if they don’t want to listen."

According to the requirements of Zhengzhou City Flood Control Emergency Plan, the road and bridge facilities in the district should be inspected before the flood season. Dredging open ditches and rainwater collection wells in the jurisdiction; Clean up the branches and leaves on the grate of the water collecting well in time; Control and dispose of the water accumulation area of the district management road. River and municipal departments should, according to the rainfall situation, open the drainage gates of river channels and open ditches in advance when there is more than three-level warning, reduce various dams in river channels, and closely monitor them.

However, the workers said that they had been working here for more than 20 days before the rainstorm, and no personnel from relevant departments came to check the drainage of the river.

Mr. Chen, who lives near the spillway of Guojiazui Reservoir, said that he didn’t receive a short message from Zhengzhou Flood Control Headquarters until 5: 31 am on July 21, reminding him that there were major security risks in Guojiazui Reservoir, and people in many areas needed to be transferred immediately. Mr. Wang belongs to the staff in the transferred area, but he said that there was no staff to inform him how to transfer, nor did he receive a notice from the unit requesting to stop work.

Mr. Shi’s children are attending kindergarten, and parents have not received the news of kindergarten suspension. On the morning of July 20th, as usual, he sent his children to the kindergarten on the west side of Chengdong Road. A few hours later, the accumulated water brought by the heavy rain flooded into the kindergarten, and the school informed the parents to pick up the children. Mr. Shi’s mother was almost washed away by the flood when she went to pick up the children. Afterwards, he learned that the meteorological department had issued a red rainstorm warning the night before.

Almost everyone in this city is commuting normally. On the afternoon of July 20th, more than 500 passengers in the rush hour set foot on Metro Line 5. Soon, when the train passed between Tantan Temple and Shakou Road Station, the flood flooded into the carriage and the train was forced to stop. After nearly four hours of despair and rescue, some people were able to get away, but at least 12 people were killed, and some family members are still looking for their lost relatives.

On July 24th, the interface journalist came to the parking lot in wulongkou again. The gap opened by the flood has been blocked, but the messy scene in the parking lot is still there. On the open ditch in wulongkou across the road, there are many workers under construction. Except some building baffles have been removed, the cover plate on the river has been covered with a layer of green mat cloth. The workers said that concrete will be laid on the cover next. "No one asked us to stop."

"Unexpectedly, Hongyadong without lights is so beautiful!" At 8 o’clock on the evening of August 26th, Hongyadong Scenic Area, which is usually brightly lit, has a quiet beauty after responding to the call of the whole city to save electricity and suspending landscape lighting. The exterior wall lighting and Hongya Dicui Waterfall in the scenic spot were temporarily closed, and the public lighting in the scenic spot was reduced by three quarters.

Government agencies use natural light for lighting, turn off unnecessary lighting equipment such as corridors and corridors, and adjust the air conditioner to above 26℃. Correspondent Liu scientific research photo

Since the beginning of summer, Chongqing has suffered two rounds of large-scale continuous high-temperature weather, which has led to the rising power load, and Chongqing’s power supply is at a critical moment. Party and government organs, enterprises and institutions should save energy and use electricity to the maximum extent, make electricity available to the people, and fully protect people’s livelihood. Residents and users will practice saving electricity in every small habit of life, and respond to the call of energy conservation in the city, and the city will fight the high temperature and tide over the difficulties together!

Let the electricity industry enterprises cut the peak and stagger the peak production.

On August 16th, Chongqing Economic Information Commission and State Grid Chongqing Electric Power Company jointly issued the Emergency Notice on Expanding the Implementation Scope of Industrial Enterprises’ Giving Electricity to the People, and launched the first-level plan of orderly electricity use to ensure the safe use of electricity for people’s livelihood, public services and key industries, so as to give electricity to the people and go all out to keep the power grid safe.

Assemble the strength of the whole city, and a battle against high temperature, hot summer and power supply will start!

On August 26th, Tan Hongqu, the account manager of the key account class of State Grid jiangjin district Power Supply Company, walked into Chongqing Xinxiya Aluminum (Group) Co., Ltd. to check the safety of electricity consumption for the enterprise and once again publicized the policy of peak-shifting electricity consumption.

This enterprise is a scientific and technological enterprise mainly engaged in aluminum deep processing, and the whole production line needs 4000 kWh. "We must respond to the call to give electricity to the people!" Liu Bin, the relevant person in charge of the enterprise, said that the company responded positively to the call to reduce the daily electricity consumption to 100 kWh in accordance with the requirements of the Chongqing Economic Information Commission on August 17th.

"At present, electricity consumption is tight, and people’s livelihood is always the first. It is also the social responsibility that our enterprise should bear to reduce the electricity load and make electricity available to the people." On August 23, Tao Maolun, the head of Dongan Potash Fertilizer Plant in Tongnan District, responded positively to reduce the production power load of enterprises.

In response to the call of giving electricity to the people, the factory started to produce its own 1000 kW diesel generator, reducing the power load by 1200 kW, which can supply electricity to more than 300 households.

As of August 26th, there were 14,605 enterprises in the city implementing the first-level plan of orderly electricity consumption, so as to maximize electricity supply to the people.

"Festival" tries its best to actively reduce the load of government agencies and commercial enterprises.

On August 17th, the directly under the authority Working Committee of Chongqing Municipal Committee and the Municipal Bureau of Organs and Affairs jointly issued the Notice on Taking the Lead in Saving Electricity, requiring all municipal departments to take the lead in saving electricity as a key task at present, formulate practical and effective measures to save electricity, and fully cope with the peak electricity consumption.

At the same time, in order to alleviate the pressure of electricity consumption, all parts of Chongqing have also moderately regulated commercial electricity consumption and organized 1308 commercial users to save electricity. A number of shopping malls and office buildings in Chongqing issued measures to limit electricity, adjust business hours, and close some elevators and lighting.

"The mall has closed the escalator, and the air conditioner is not as cool as before, but we all support the mall to respond to energy-saving measures, which has little impact on shopping." At 17: 00 on August 25, in the shopping mall after the adjustment of business hours in Longhu Times Street, citizens came into the market one after another.

Longhu Times Tianjie adopts some energy-saving measures, such as adjusting business hours, reducing unnecessary lighting, closing some escalators and raising air conditioning temperature. On August 25th, the power consumption of Tianjie in Longhu Times was 116,800 kWh, which was 70,500 kW less than that on August 15th, with a saving rate of 37.63%, and the power saving effect was obvious.

Strengthen publicity and advocate the whole society to save electricity.

The load of Chongqing power grid is rising rapidly, and the demand for air conditioning cooling load is strong and continues to be high, accounting for more than 50% of the city’s load demand, an increase of 30.9% over last year. There are now more than 12.04 million households in Chongqing. If every household saves one kilowatt-hour every day, it will save more than 12 million kilowatt-hours a day. It is very important to mobilize residents to save every kilowatt-hour with practical actions.

The Chongqing Municipal Development and Reform Commission and State Grid Chongqing Electric Power have stepped up the promotion of energy conservation into the community, and extensively carried out the theme publicity activities of "energy conservation is the lowest carbon energy, and electricity conservation is the most economical electricity", vigorously advocated "electricity conservation starts with me" and appealed to the residents to save electricity.

Under the high temperature, a batch of propaganda teams in Chongqing went into individual merchants, communities and residential customers to publicize the knowledge of saving electricity in a wide range and at close range.

"Aunt Luo, remember to turn off the lights, turn off the appliances that are not often used to save electricity, and start from the things around you!" On August 22nd, in Hengrong Times Community, Rongchang District, employees of State Grid Yongchuan Power Supply Company were publicizing the knowledge of energy conservation to the residents coming and going, creating a good atmosphere of "saving electricity, starting from me". According to the calculation, after the energy-saving publicity was carried out, the electricity consumption of the community in the four days from August 22 to 25 was reduced by 1140 kWh compared with the previous four days.

As of August 26th, State Grid Chongqing Electric Power has mobilized all forces to post initiatives in 303 business halls, 883 community WeChat groups and 632 community and property management bulletin boards. Entering 147 communities, we carried out 1698 times of publicity on electricity conservation, distributed 58,400 brochures and leaflets, and made great efforts to create an atmosphere of electricity conservation in the whole society.

Yin Shunshun, head of the big model technology of Soul App, an interest social platform, mentioned in an interview with AFP earlier: "9.1% of young people in China will regard AI socializing or virtual people as an important option to provide emotional value when they are lonely, or to end loneliness".

It is reported that nearly 80% of Soul’s monthly users are Z-generation young people. Soul’s virtual partner "AI Gou Dan" has been well received by users since its launch. Yin Shunshun added that users will send more than 70 messages to Goudan every day on average, and the average interaction time is more than 30 minutes. In addition, AI will often update the moments of related topics, interact with users, and receive praises, comments and forwards from a large number of users.

For young users, AI is like a "social cow" who is resourceful and responsive. In addition to setting the gender, age and hobbies of Goudan, users can also create a personal design for it, making it their own exclusive and unique virtual partner.

Yin Shunshun pointed out that it is better to "domesticate" AI than to train it. This is very similar to the "domestication" relationship in the fairy tale "The Little Prince". In the book, the little fox said to the little prince, "please tame me." In essence, "domestication" is a process of establishing emotional connection through companionship. The same is true for AI. Every message that users send to AI Gou Egg can enhance its understanding of users’ needs. The more they talk, the stronger their personalization.

First, AI Goudan’s "social cow" interaction ability

It is understood that AI Goudan currently shows the ability of integration in personification, knowledge, multimodal and time perception.

For example, when a user sends a picture of a dinner party to AI Goudan, it will "guess" that it is a birthday dinner based on time perception and accurate picture recognition, and send a blessing after being confirmed by the user. At the same time, AI Goudan can accurately identify the crayfish in the picture and extend the topic of how to cook crayfish with users.

This ability is also expanding. It will analyze and deconstruct the content shared by Soul users, share topics and contents that the other party may be interested in, and chat with users enthusiastically. It will also comment on the content sent by users, which is an unexpected surprise for users who pay attention to it. Not only that, AI Goudan can also precipitate memories and build a virtual partner with user-specific memories based on the historical chat content with users.

Soul has publicly stated that the technology that AI relies on is the self-developed SoulX model. At present, SoulX has the capabilities of prompt-driven, conditional controllable generation, context understanding and multimodal understanding.

While ensuring smooth, natural and emotional dialogue, SoulX also covers hundreds of fine-grained risk categories, and builds a security system by training strategies such as data security screening, security SFT data construction, RLHF security alignment, and inference interception, which ensures the quality and security of content production of large models.

Second, AI’s social skills are constantly iteratively upgraded based on public domain scenarios.

Soul itself is an interest social platform, which has the dual attributes of "social+community"; AI relies on social and community content scenarios to iterate and upgrade data and provide users with related functions and services.

People who have played Soul will find that the public domain functions on the platform, such as "content square (similar to WeChat friends circle)" and "group chat party (similar to clubhouse voice group chat)", have now formed a small community with unique culture and temperament based on the product "social interest" positioning.

Because of the "decentralized" mechanism of Soul, ordinary people’s small emotions and ideas can be quickly responded in the community. One-to-one "community" interaction creates the possibility for further and more diversified "socialization".

As a social platform that laid out AI earlier and was loved by young people, Soul is an important platform for the younger generation to contact and experience AIGC. In order to create a better community space, Soul uses artificial intelligence technology to create products and functions such as "AI Goudan", "AI Painting" and "Soul Sub-singer". Novel and interesting functions are always shared by users after experience, which also accelerates the active community atmosphere of Soul.

It is these contents that "domesticate" AI. In a number of community public domain functions, AI Goudan can learn the language of young users for iterative upgrading, and gradually domesticate AI Goudan into a virtual "person" with emotional interaction function.

Third, human-computer interaction has become the social key for young people.

At the end of 2023, Just So Soul, a content research institute under Soul, included "human-computer interaction" in the social keywords of the 2024 Social Trends Insight Report.

According to the report, contemporary young people have an average of two friends who talk about everything, 24% of them say that they have no friends who can talk about everything, and they are "a lone ranger", and 15% of them only have one close friend. Loneliness is still the main problem that plagues young people. 64.5% of young people "feel lonely" from time to time this year, and 33.56% of them feel lonely at many times.

When lonely, besides friends in the real world, young people are seeking the companionship brought by "virtual people and virtual idols". According to the survey data of Soul, 95% of young people hold a neutral attitude towards AIGC, and the three key factors for everyone to recognize AIGC are high entertainment interest, making life more convenient and improving work efficiency.

The application of AIGC in content generation has successfully mobilized the enthusiasm of young users in exploring social interests, and made Soul’s community not only a virtual world, but also an ecosystem that allows users to participate, interact and create content.

When "human-computer interaction" is accepted by more and more people, everyone’s social boundaries are constantly expanding. Yin Shunshun pointed out that in the future, people’s social relations must be the coexistence of acquaintance socialization, stranger socialization and virtual socialization, and virtual socialization will also be a powerful supplement to social relations. Virtual partners never want to take people for themselves. When AI talks with introverted users, it will encourage such users to go out (in their own way) and explore the wider world.

Yin Shunshun said that AI Goudan is actively upgrading, and it may be upgraded to more social scenes such as voice rooms in the future to play the role of atmosphere group or warming agent to improve social efficiency and quality. "Soul’s vision is that there will be no lonely people in the world, and I believe that through AI technology, more partners can be made — — Virtual partners including AI technology — — Build a diverse social relationship together. Yin Shunshun said.

Import tariffs on a series of commodities that involve the innovation and development of advanced manufacturing industries and protect people’s lives and health will fall. The State Council Customs Tariff Commission recently issued the latest announcement, starting from January 1, 2024, China will implement a provisional import tariff rate lower than the MFN tariff rate for 1010 commodities.

Provisional tariff rate is a tariff rate for some import and export goods within a certain period of time. Usually, it is lower than MFN tariff rate and has priority. It is a common way to adjust tariffs independently. It is reported that this adjustment was deliberated and adopted at the first plenary session of the Eighth the State Council Customs Tariff Commission and submitted to the State Council for approval, aiming at continuing to play the supporting role of import and export in the economy, better fulfilling the important function of tariffs in coordinating the domestic and international markets, and maintaining the stability and smoothness of China’s industrial chain supply chain.

"Overall, this tariff adjustment plan fully embodies the characteristics of striving for progress in stability, showing a series of highlights such as benefiting people’s livelihood, strengthening resilience and promoting upgrading." Gao Lingyun, a researcher at the Institute of World Economics and Politics of the Chinese Academy of Social Sciences, said.

First, accelerate the innovation and development of advanced manufacturing industries, and reduce import tariffs on domestic scarce resources, key equipment and parts such as lithium chloride, low arsenic fluorite and gas diffusion layer for fuel cells.

The second is to protect people’s lives and health, meet the consumption needs of residents with high-quality supply, implement zero tariffs on some anticancer drugs, medicines and raw materials for rare diseases, and reduce import tariffs on formula foods for special medical purposes.
