Letter from youth

　　The second letter: The word "social fear" is often jokingly mentioned by students, but I am distressed because I am a veritable "social fear". For example, I always hide from the group activities at school. At the last class reunion, I obviously wanted to enhance my feelings with my classmates, but I was terrified at the thought of communicating and interacting in front of everyone, and finally I made an excuse not to go. In class, even if I know the answer, I seldom raise my hand to speak, for fear that I will be laughed at by my classmates if I make a mistake.

　　I have seriously reflected on it and think it may be influenced by social media. In the online world, I can easily show my beautiful side, and at the same time I can see the life carefully built by some people. But in real life, in the face of real social scenes, I will shrink back because I am afraid that my performance is not perfect.

　　I especially want to get rid of this "social fear" state, be able to associate with people freely and actively participate in various activities, but I don’t know where to start. Can you give me some suggestions?

——————————

　　Create a more inclusive and supportive environment for young people.

　　 Zhang Yingjun (Teacher, Mental Health Education and Consultation Center, Beijing Normal University)

　　Judging from the description of this classmate’s letter, "social fear" has become an important label for him to describe his social psychology. Moreover, some young people laugh at themselves and humorously reflect their embarrassing and evasive behavior in social interaction.

　　Social phobia disorder, also known as Social Anxiety Disorder, is manifested as a psychological state of intense fear and anxiety about social occasions or public performance. Patients are often worried about making a fool of themselves in front of others, being judged or laughed at, so they avoid social activities or show obvious anxiety in social situations. According to a survey, as many as 40% of young people said that they have different degrees of "social phobia", among which the proportion of women is slightly higher than that of men. However, it is worth noting that not all young people who call themselves "social phobia" meet the clinical diagnostic criteria of social phobia, and they may just show a tendency of social avoidance or anxiety.

　　On a global scale, this kind of mood and state of avoiding social interaction is common among young people, which affects their interpersonal relationship, reduces social support, increases loneliness, and the risk of emotional problems such as depression and anxiety, and may have a negative impact on social function and quality of life.

　　So, what caused the "social fear" of young people?

　　First of all, family environment and social pressure are the deep-seated reasons for young people’s social fear. Family environment has a profound influence on young people’s social ability. Kohut, a psychologist, believes that parents’ lack of mirror reflection and recognition in their interaction with their children (parents need to respond appropriately to their children’s values, achievements and achievements like mirrors-editor’s note) leads to children’s lack of healthy narcissism (self-confidence) and fear of others’ evaluation, which is the root cause of "social fear". Parents’ expectations, family education atmosphere and childhood experience may all be important factors affecting young people’s social psychology. For example, children who have been denied by their parents for a long time may lack independence and self-confidence, and are more likely to feel uneasy and anxious in social situations. The competition in modern society is fierce, and young people are facing enormous economic pressure and career challenges. These external pressures not only affect their quality of life, but also aggravate their social anxiety to some extent. In social situations, they may be worried that their performance does not meet the expectations or standards of others, so they choose to avoid it.

　　Secondly, the lack of self-efficacy and negative self-evaluation are the direct reasons for young people’s "social fear". Self-efficacy refers to an individual’s confidence level in completing a task or coping with a certain situation. In social situations, many young people lack self-confidence and are afraid that they can’t cope with others’ eyes and comments. At the same time, negative self-evaluation also plays an important role in the emergence of young people’s "social fear". They often criticize their appearance, words and deeds excessively, thinking that they are not perfect and prone to make mistakes, which affects their self-esteem and makes them feel more nervous and uneasy in social situations.

　　Thirdly, social media and virtual socialization are external factors that aggravate young people’s "social fear". With the popularity of the Internet and the rise of virtual social media, the way people communicate has undergone earth-shaking changes. Although social media provides convenient communication channels, it also weakens the ability of face-to-face communication. Many young people are addicted to the virtual social world, but ignore the cultivation of social skills in reality. This phenomenon is called "otaku culture", that is, people prefer to stay at home and communicate with others through electronic devices instead of going out to participate in social activities in real life. Information overload and algorithm recommendation on social media may also lead to self-doubt and anxiety among young people. They may feel inferior and uneasy because their appearance, talent or social skills are not as good as others. At the same time, the negative information on social media may also aggravate the social pressure of young people, making them more nervous and anxious when facing social occasions.

　　How to deal with the social fear of young people?

　　First of all, society should create an inclusive and supportive environment. The society should establish a diversified value evaluation system to help parents reduce anxiety, recognize their children more, and enhance their self-confidence and self-efficacy. Family members should give young people enough care and support, encourage them to actively participate in social activities, and provide necessary help and guidance. When young people encounter social difficulties, family members should give positive feedback and suggestions to help them establish correct coping strategies and mentality. At the same time, young people should also actively reflect on the influence of society and family, build a healthy system of values and self-evaluation, actively interact with family and others, increase connections and establish a social support system.

　　Secondly, young people should establish positive self-awareness. Cognitive reconstruction is an effective way to help social terrorists identify and change negative thinking patterns and behavior habits. For young people, establishing positive self-awareness is the first step to overcome "social fear". They need to learn to accept their imperfections and shortcomings and stop being harsh and critical of themselves. At the same time, they should also learn to look at the evaluation of themselves and others with a positive eye, and not care too much about the opinions and attitudes of others. Positive self-suggestion can help them enhance their self-confidence and coping ability, thus reducing social anxiety. For example, positive psychological hints such as "I can cope with this social occasion" and "I have my own advantages and strengths".

　　Thirdly, young people should improve their social skills. Social skills training is one of the effective means to overcome social phobia. It can help young people improve their social skills and self-confidence and better cope with the challenges in social situations. Young people can actively participate in various social activities, such as interest groups, community activities, volunteer activities and so on. These activities can not only provide more social opportunities, but also help them build positive social experiences and interpersonal relationships. In the process of participating in activities, young people can gradually learn social skills such as how to establish contact with others, how to express their views and feelings, and how to deal with conflicts and differences.

　　In addition, young people should also pay attention to improving their physical and psychological qualities. A healthy lifestyle plays an important role in alleviating "social fear". Regular work and rest, healthy diet and moderate exercise can improve physical fitness, enhance psychological endurance, and help release stress and relieve anxiety. At the same time, young people can also try some relaxation training, such as deep breathing and meditation.

　　Social fear is not an insurmountable obstacle. Society, families and individuals should work together to create a more inclusive and supportive environment for young people and help them grow up healthily. By redefining their own value system, reconstructing negative self-cognition, training social skills and maintaining a healthy lifestyle, young people can gradually cope with social fears and enjoy the fun and sense of accomplishment brought by social interaction. In this process, the uniqueness of each young person needs to be understood and respected. Young people bravely face social challenges and pursue their own happiness and happiness also need support, encouragement and blessing.

I. Basic knowledge

1.What is geological disaster?

Geological disasters usually refer to disasters that cause people’s lives or property losses due to geological processes; Natural geological disasters are induced by rainfall, snow melting, earthquakes and other factors; Man-made geological disasters are caused by engineering excavation, stacking, blasting and soil abandonment. Common geological disasters mainly refer to six kinds of disasters related to geological action, such as mountain collapse, landslide, debris flow and ground collapse, ground fissure and ground subsidence, which endanger people’s lives and property safety.

There are four main geological disasters in Guangxi: collapse (including dangerous rocks), landslide, debris flow and ground collapse. This knowledge reader mainly introduces these four kinds of geological disasters.

2.What is the hidden danger point of geological disasters?

Hidden dangers of geological disasters include unstable slopes, potential landslides, potential collapses, potential mudslides and potential ground collapses that may endanger people’s lives and property, as well as landslides, collapses, mudslides and ground collapses that have occurred but are still unstable.

3.What is the hidden danger area of geological disasters?

The hidden danger area of geological disasters refers to the area or section where geological disasters are likely to occur and may cause casualties or property losses under the action of heavy rainfall and human engineering activities.

Second, collapse

1.What is collapse?

Collapse refers to the geological phenomenon that the rock mass or soil mass on the steep slope suddenly breaks away from the mountain under the action of gravity and collapses, rolls and accumulates at the foot of the slope or in the valley. Collapse is also called caving, collapse or collapse.

Collapse can occur in loose soil, bedrock, and where the two kinds of rocks develop together. What happens in the soil is called landslide; What happens in rock mass is called rock collapse.

When the collapse occurs in the mountain and the scale is huge, it is also called landslide; When collapse occurs on rivers, lakes or coasts, it is called bank collapse.

2.What is a dangerous rock mass?

Dangerous rock mass refers to the block stone located on the steep hillside and separated by cracks. Some of these stones are very large, and some are just a boulder on a steep slope. Dangerous rock mass may fall from steep hillside due to vibration or rainstorm; Sometimes strong winds may blow unstable boulders down. The situation of dangerous rock mass is common in limestone mountain areas of Guangxi.

3.The harm of collapse to human beings

Collapse often destroys and buries houses and engineering facilities in places where human activities take place, endangering human life and causing property losses.

4.When is it easy to collapse?
(1) In the process of rainfall or slightly delayed. This is the time when the most collapses occur;

(2) During a strong earthquake or aftershock;

(3) In the process of excavating the toe of the slope or lagging behind for a period of time;

(4) The initial stage of reservoir impoundment and the peak period of rivers;

(5) After strong mechanical vibration and big blasting.

5.Which places are prone to collapse?

Generally, the slope that may collapse has the following macroscopic characteristics:

(1) The slope is more than 45 degrees and the height difference is large, or the slope is an isolated mountain mouth or a concave steep slope.

(2) The internal cracks of the slope are developed, and the tensile cracks have developed in the upper part of the slope, and the cracks and cracks cutting the slope are about to penetrate, which makes it separate from the parent body (mountain).

(3) There is an empty space in front of the slope, or there are collapses, which indicates that there have been collapses and they may happen again in the future.

The slope with the above characteristics is the possible collapse, especially when the upper tension cracks continue to expand and widen, the speed increases suddenly, and small falls continue to occur, which indicates that the collapse will happen soon and is in a state of explosive.

The following signs may appear before the collapse:

(1) The cracks in the collapse gradually expand, and the front edge of the dangerous rock mass has the phenomenon of falling and falling, and small collapses and small collapses occur continuously;

(2) New cracks appear on the top of the slope, and an abnormal smell is smelled;

(3) I occasionally hear the sound of tearing and rubbing of rocks;

(4) Abnormal heat, radon, underground water quality, water quantity, etc.

Precursor formula of collapse

The cliff is steep and fractured, and the rockbare/show (one’s teeth)Mouth-shaped;

Small collapses often occur, and the stones with abnormal smells rattle.

When the collapse occurs, if you are outside the scope of the collapse, you must bypass it; If you are under the collapsed body, quickly escape to both sides, the sooner the better; If you feel the ground shaking, you should also immediately flee to the stable areas on both sides.

8.How to prevent collapse

Prevention of collapse:

(1) Don’t build houses, build roads and shelter from the rain under the dangerous rocks on the steep slopes that have not been treated, and don’t climb the dangerous rocks when it rains.

(2) Excavation of pillars in old mines (old kilns) is likely to cause roof collapse disaster, and the mined goaf should be backfilled and the empty mine holes should be buried.

Third, landslides

Landslide refers to the geological phenomenon that the soil or rock mass on the slope slides down the slope as a whole or dispersedly under the action of gravity under the influence of rainfall and rainwater infiltration, river erosion, groundwater activity, earthquake and artificial slope cutting, commonly known as "ground slip", "mountain walk", "mountain collapse", "mountain peeling" and "soil slip".

Landslide is one of the main natural disasters in mountainous areas, which often causes huge losses and even devastating disasters to industrial and agricultural production and people’s lives and property.

The main hazards of landslides in rural areas are destroying farmland and houses, hurting people and animals, destroying forests, roads, agricultural machinery facilities and water conservancy and hydropower facilities, and sometimes even causing devastating disasters to rural areas. Landslides located near towns often bury houses, injure people and animals, destroy fields, and destroy various facilities, resulting in power outages, water cuts, work stoppages, and sometimes even the entire town. Landslides in industrial and mining areas can destroy mine facilities, hurt workers, destroy factories, make mines stop production and often cause heavy losses.

Landslides often cause great harm in water conservancy and hydropower projects, highways, railways, river transportation and marine engineering, and often produce some secondary disasters, which indirectly harm human beings, such as blocking rivers, overflowing upstream rivers or bursting after blocking rivers into lakes, and causing floods; Sometimes, the debris flow is induced by the superposition of rainstorm or flood, which causes more serious damage.

Landslides generally go through four stages from gestation to formation: cracking, creep, sliding and stability.

The time of landslide occurrence is mainly related to various external factors that induce landslide. There are roughly the following rules:

(1) simultaneity. Some landslides move immediately after being affected by inducing factors. Landslides will occur when heavy rains and earthquakes occur and unreasonable human activities, such as excavation and blasting, etc.

(2) Hysteresis. Some landslides occur later than the inducing factors, such as rainfall, snowmelt and human activities. This hysteresis law is most obvious in rainfall-induced landslides. Generally speaking, the looser the landslide, the more developed the cracks and the greater the rainfall, the shorter the lag time. The greater the intensity of human activities and the lower the stability of landslide, the shorter the lag time.

Landslides generally occur in areas with bedding slopes, relatively broken inclined rock masses, large ups and downs of mountains and poor vegetation coverage. The mountainous and hilly areas with frequent engineering construction and rural slope cutting areas are also landslide-prone areas; Earthquakes lead to loose mountains and broken rocks in disaster areas, and landslides are also prone to occur under the action of aftershocks or heavy rains.

6.Precursor of landslide

The precursor characteristics of landslide are obvious, and there are cracks on the hillside;

The foot of the slope is loose or swollen, and there is subsidence in the middle and upper slopes;

Slope buildings are deformed, and trees are as drunk as machete forests;

Water suddenly appears in dry places, and the well water drops and rises from time to time;

There was an abnormal noise in the ground, and the livestock panicked and reacted differently.

When a landslide occurs, you should evacuate from both sides of the landslide boundary and never escape along the sliding direction. If the landslide slides fast, it’s best to hold a big tree still and not let go.

After the landslide happened, it did not stabilize immediately, and it will even continue to happen. Therefore, do not immediately enter the disaster area to search for property.

(1) Do not build roads or houses in landslide areas or areas with landslide risks. The newly selected building site should avoid rivers, lakes (reservoirs) and gullies to cut steep slopes as much as possible;

(2) Excavating soil at the foot of steep slope is easy to induce collapse and landslide;

(3) The retaining wall behind the house must leave drainage holes;

(4) The building should be built at a certain distance by cutting the slope, and the bed should not be placed on the side near the hillside. When it rains heavily at night, attention should be paid to inspecting whether the slope is abnormal, etc.

(5) Building houses on slopes are most likely to cause landslides, so geological personnel should be invited for exploration before excavation;

(6) Houses should be selected as far as possible on or under the slope of the reverse slope (reverse slope means that the slope inclination is opposite to the rock stratum inclination).

IV. Debris flow

Stimulated by water sources such as rainstorm, melting ice and snow, or dam break in reservoirs and ponds, the solid deposits in hillsides or valleys are mixed in the water, flow rapidly downstream along the hillsides or valleys, and accumulate at the foot of hillsides or at the place where they leave the mountain pass, thus forming a debris flow.

Debris flow often erupts suddenly and violently, rushing down the steep ravine. The valley is like thunder, which can carry huge stones and wash a lot of sediment stones out of the ravine in a short time, which is extremely destructive and often does great harm to human life and property.

According to the valley landform, it can be divided into valley debris flow and slope debris flow.

Gully type: it is formed along the valley, and the basin is long and narrow with large scale.

Slope type: Slope terrain, short ditch and steep slope, small scale.

Debris flow is a special torrent with sudden outbreak and short duration in mountainous areas, which contains a lot of solid substances such as sediment and stones and has strong destructive power. The total volume of solid substances generally exceeds 15%, and the highest can reach 80%. The vanguard is a thick and turbid torrent, which forms a "faucet" with a height of several meters to more than ten meters. It has a very strong scouring and carrying capacity and is extremely fast. It can discharge hundreds of thousands or even millions of cubic meters of solid substances in a very short time, and can carry hundreds of thousands of tons of boulders, with amazing destructive power. Debris flows frequently occur in many mountainous areas of China, especially in the western areas of Gansu, Sichuan and Yunnan provinces, where heavy rains are bound to occur. On August 8, 2010, the catastrophic mudslide in Zhouqu, Gansu Province instantly destroyed the whole county, killing more than 1,000 people and making more people homeless.

Gully with the following three conditions is the most prone to debris flow:

(1) The mountain in the upper valley is broken, and the thickness of loose earth and stone on the hillside is large;

(2) The slopes on both sides of the gully are steep, and the height difference between the gully head and the gully mouth is large;

(3) Gullies with much rain and frequent floods in summer flood season.

The time of debris flow occurrence has the following three laws:

(1) Seasonal: The outbreak of debris flow is mainly stimulated by continuous rainfall, heavy rain, especially heavy rain and other concentrated rainfall. Therefore, the time law of debris flow is consistent with the time law of concentrated rainfall, which has obvious seasonality. Generally occurs in rainy summer and autumn.

(2) Periodicity: Debris flow is influenced by rain, flood and earthquake, but rain, flood and earthquake always appear periodically. Therefore, the occurrence and development of debris flow also has a certain periodicity, and its activity cycle is roughly consistent with that of rain, flood and earthquake.

(3) Debris flow usually occurs at the peak of a rainfall or after continuous rainfall.

(1) The normal running water in the river (ditch) bed suddenly stops flowing or the flood suddenly increases (with more firewood and trees).

(2) An abnormal roar suddenly came from the upper reaches of the river (ditch) valley. The sound is obviously different from that of locomotives, wind and rain, thunder and lightning, blasting, etc., which may be caused by the impact of boulders carried by mudslides.

(3) Have a slight sense of vibration.

Choose the shortest and safest path to run to the hillside or highland on both sides of the valley, and avoid running along the direction of debris flow; Don’t stay in the hollow with large slope and thick soil layer; Don’t climb trees to avoid, because debris flow can sweep away all obstacles along the way; Avoid concave banks with curved channels or convex banks with narrow places and low heights; Don’t hide under the steep mountain; You can’t return to the danger zone immediately after a long period of rain or heavy rain, or after the rain has just stopped; After more rain during the day, pay close attention to the rain at night, and it is best to leave early.

Prevention of debris flow:

(1) Do not build roads or houses in areas where mudslides or debris flows are dangerous. Villages and houses should be built at a safe height on both sides of the creek, not in depressions and gullies.

(2) Don’t pile a lot of soil in the ditch to prevent debris flow.

(3) Heavy rain, melting glaciers and melting snow-capped mountains are easy to cause mudslides, so preventive measures should be taken before.

(4) After the rainstorm, the debris flow will still occur, so we should wait for some time after the rain before going back.

V. Ground collapse

Ground collapse is a dynamic geological action or phenomenon that under certain conditions, the shallow rock and soil mass on the surface collapses downward and forms a pit on the ground. The ground collapse in Guangxi mainly includes karst ground collapse and goaf collapse.

The main hazards of collapse are the destruction of houses, railways, highways, mines, reservoirs, dams and other engineering facilities, resulting in house collapse, road interruption, reservoir leakage, dam and dike collapse and cracking. In addition, it also destroyed land resources, destroyed a large number of farmland, and deteriorated the environment in some cities and mining areas.

The main dynamic factors causing ground collapse are earthquake, rainfall, underground excavation, massive pumping and drainage, etc.

(1) The sudden rise and fall of the water level in Jing Quan, the sudden turbidity of water color or sand turning and steaming.

(2) Annular cracks appear on the ground and expand continuously, resulting in local ground heave or subsidence.

(1) After the collapse, the collapse pit of the adjacent building should be filled in time to avoid affecting the stability of the building.

(2) The ground cracks near the building should be filled in time, and the surface water should be intercepted in the subsidence pit of the ground to prevent it from injecting people.

(3) The severely cracked buildings should be temporarily closed, and the measures to be taken should be determined only after the dangerous houses are identified.

(4) Residents living in mined-out areas formed by mining hollowing out should pay attention to whether there are obvious signs such as deformation and cracks on the ground in front of and behind the house during flood season, and whether surface water seeps into the ground in large quantities and quickly during heavy rain. If any abnormality is found, you should immediately evacuate and notify the relevant departments. Don’t risk staying in the same place or in the living room to avoid possible collapse and casualties.

(1) Mines and karst areas are prone to collapse, so special attention should be paid to prevention when living or moving in these areas.

(2) Strong pumping in the hidden karst area is easy to cause ground collapse.

(3) In case of ground collapse cracks, it should be filled with sand and gravel in time and plastered with clay.

Sixth, the essentials of hedging and self-help

The flood season, especially the period of heavy rainfall, is a period of high incidence of geological disasters, so we should pay attention to listening to the weather forecast and improve the awareness of disaster prevention.

Report the precursors of geological disasters to the local government or relevant departments immediately.

In order to avoid danger urgently, under the guidance of professional and technical personnel and with the cooperation of relevant departments of counties, townships and villages, one or several safety sites are selected in advance as temporary places to avoid disasters. These disaster shelters are relatively safe places. When a local disaster comes, you should try your best to go to the disaster shelter on the premise of ensuring personal safety.

4.Evacuate according to the evacuation route

As far as possible, the route to leave the danger zone should avoid the slip direction of landslide, the collapse direction of collapse or the route where debris flow may pass, and cross the danger zone as little as possible. The road spread along the ridge is safer than the road spread along the valley.

5.Remember the warning signs.

Evacuation signals (such as broadcasting, beating gongs, drums, etc.) are agreed in advance, unique, and can’t be used indiscriminately, so you must remember to evacuate quickly when you hear the signal, and you can’t hesitate.

6.To publicize the knowledge of disaster prevention and control to family members and the masses.

7.Three-character scripture for avoiding danger of collapse and landslide

Before the disaster, there were anomalies; Water mutation, animal shock;

The forest is drunk and the foot of the slope is convex; Cracks appear, cracks expand;

Rock crack, rock collapse; The mountain is steep and easy to collapse;

In case of emergency, flee on both sides; Stop on a gentle slope and get away from it.

8.Three-character scripture of debris flow avoidance

Debris flow, which is harmful, not only hurts people, but also destroys homes;

Not mysterious, regular, formed in the gully;

On rainy days, listen to the forecast, observe carefully, and be on guard;

The water becomes muddy, the rocks are sandwiched, the valley is faint, and there is a slight earthquake;

Urgent report, no procrastination, timely withdrawal, listen to the arrangement;

Life first, wealth second, abandon the burden and protect life;

Stride, don’t look back, go high, stay away from the concave;

It clears up, the mud stops flowing, don’t worry, go home slowly.

9.Three-character meridian for avoiding danger from ground collapse

Seisensui, sudden rise and fall, turbid water, or turning sand;

Ground fissures, growing, locally bulging, or sinking;

Rich in mineral deposits, easy to be mined out, large collapse, and frequent this;

In karst area, there are many soil holes, so pumping is less to prevent collapse.

10.Hedging formula for building houses in mountainous areas

Pay attention to the location of building, think more about the slope ditch,

Ask an expert if the situation is unknown, and don’t make your own opinions.

Don’t choose the site for the steep slope of the concave land, and don’t build houses under the side wall of the cliff.

Don’t believe in geomantic superstition, but advocate scientific thought.

Don’t dig at the foot of the slope, cut the slope and grade it and add support.

Ponds should not be built on slopes, and muck should not be piled at gullies.

Rivers and ditches should not be changed easily, and drainage should be proper.

Infrastructure should be valued, and geological safety should not be forgotten.

Seven, how to prevent geological disasters when building houses by cutting slopes.

Guangxi is a mountainous province. For a long time, in order to protect the limited arable land, many people in mountainous areas can only build houses by cutting slopes. According to the data from Guangxi Geological Environment Monitoring Station, from 2006 to 2017, there were 215 geological disasters such as collapses and landslides caused by cutting slopes to build roads and houses in Guangxi, with 239 deaths and 176 injuries. This shows that the harm of building houses by cutting slopes is great. Therefore, it is necessary to do a good job of prevention scientifically and effectively avoid disasters.

In building houses in rural areas, we should earnestly take preventive measures against geological disasters. In accordance with the unified arrangement of the new rural construction plan, large-scale construction such as villages and towns must carry out geological disaster risk assessment. Even if farmers build houses individually, they should consult people with professional knowledge of geological disasters if possible to take precautions. Only in this way can we ensure the safety and reliability of our housing.

First of all, there should be a protective distance if there is space. How to calculate this safe protective distance? For example, if the slope is 10 meters high, then our safety protection distance will be greater than 10 meters, so the house built in this way will be relatively safe. But it may be difficult to do this in the vast mountainous rural areas. If it can’t be done, what should we do? Then we must take preventive measures. First, we should do a good job in retaining wall support and slope protection. The second thing is to cut the slope. The whole slope is cut below the safe slope, which is about 40 degrees, and the slope should be cut below 40 degrees. Third, we should do a good job in intercepting and draining the slope. It is necessary to do a good job of intercepting the drainage ditch with three lights, and intercept all the water flow on the hillside to the foot of the slope. Tall trees and dense bamboo forests cannot be planted on the hillside.

On June 12, 2008, Li, who lives in Liuwang Village, Licun Town, Rong County, Guangxi, would never have thought that a small collapse in the back hill would have ruined a family of five. Li once opened a motorcycle repair shop in Rongxian County. Because it rained for many days, Li never went home. After the rain cleared up, on June 11th, Li rushed home with his motorcycle to reunite with his family. Never imagined that at one o’clock in the morning on the 12th, affected by the rain a few days ago, the hillside behind the rain-filled house suddenly collapsed, causing a family of five to be buried in the mud while sleeping. After investigation by experts, it was found that the side of the house of the victim was next to a steep slope that was not too high, and the earth collapsed at the scene was not large, only less than 100 cubic meters. Why did this seemingly insignificant little collapse cause the disaster of a family of five? In fact, this accident can be completely avoided. At that time, five people slept in a bed, and when they collapsed, they just buried the bed on the side of the mountain, causing death. If you had a little awareness of geological disaster prevention at that time, you could have avoided the accident by putting the bed on the other side of the house.

When encountering cracks, falling blocks and water leakage around the house, which may lead to geological disasters, you must obey the instructions of the township government, the staff of the land department or the monitor, evacuate and avoid in time, and pay attention to check whether there are hidden dangers on the slope of the house when you return. You can’t return to the house until the hidden dangers are eliminated and the experts agree.

For example, on September 6, 2013, affected by the previous typhoons "Yute" and "Tanmei", heavy rain fell in Guiping City, Guangxi, causing geological disasters such as collapses and landslides in many places. In view of the possible danger, at 8: 30 in the morning, when the director of the National Land Institute of Mugui Town in Guiping City and the staff of the town government inspected Team 9 of Guotuntun in Pinghe Village, they found that a villager’s house was in danger due to slope cutting, and the staff immediately asked them to evacuate temporarily. However, at noon, the owner of the house returned to the house with luck when he saw nothing. As a result, it collapsed in the afternoon and the two were buried in the mud instantly.

5.Building site selection four "don’t"

Don’t build houses on landslides,

Don’t build a house in the valley,

Don’t build houses under steep slopes.

Don’t cut slopes to build houses at will.

6.Establish a joint insurance system to prevent geological disasters of building houses by cutting slopes.

All localities should investigate the situation of building houses on cut slopes or on slopes within their jurisdiction, register and establish address books for households with risks, and conduct joint defense grouping for households with hidden dangers on cut slopes or on slopes under the jurisdiction of village (neighborhood) people’s groups, designate team leaders, implement man-to-man and household-to-household marking, and similar households assume the responsibility of reminding each other and protecting each other. Once early warning notices and information such as flash floods and heavy rainfall geological disasters are received, households should notify each other and do emergency evacuation and prevention work.

The establishment of the township (town) people’s government overall responsibility, to the village (neighborhood) people’s group as a unit, the masses as the main body of geological disaster prevention joint insurance system. All tenants who have hidden dangers of geological disasters when building houses on slopes or near slopes should implement the joint guarantee system. For people who have no communication tools, widowed elderly people, left-behind children, five-guarantee households, etc., the local government should designate special personnel to provide joint insurance with them, take charge of their safety, ensure that they can get early warning notices in time, and make timely preparations for disaster prevention.

Eight, how to prevent geological disasters in flood season

Guangxi is a province (region) with frequent geological disasters, especially in the flood season, the possibility of various geological disasters is greatly enhanced. Geological disasters, such as collapse, landslide and debris flow, often wreak havoc in the flood season. Their occurrence is like a big mouth that may devour people’s precious lives and property at any time.

Therefore, when the flood season comes, we should firmly establish a high sense of responsibility, strengthen the awareness of "walking on thin ice", take the prevention and control of geological disasters in flood season as a "life project", fight the tough battle of prevention and control of geological disasters in flood season in 2020, and hand in satisfactory answers to more than 50 million villagers in Guangxi.

Strengthen the investigation and inspection of hidden dangers of geological disasters. The people’s governments of cities and counties should organize forces to carry out geological disaster inspection and investigation, and do a good job in "pre-flood inspection, mid-flood inspection and post-flood review", especially in areas prone to geological disasters such as complex geological conditions, high slope areas, mined-out areas, tailings ponds, construction sites and hillsides near villages, without leaving any dead ends.

Strengthen the revision and exercise of geological disaster emergency plan. According to the actual situation, all localities should revise the emergency plan for sudden geological disasters in a timely manner, enhance the pertinence, effectiveness and operability of the plan, and ensure that the emergency response work is carried out quickly, orderly and efficiently when disasters occur. The main hidden danger points of geological disasters should be "one point one case". Local people’s governments in areas prone to geological disasters should organize pre-plan drills, find weak links, and improve and optimize pre-plans.

Strengthen the early warning and forecasting of geological disasters. Meteorological, water conservancy and natural resources departments at all levels should strengthen coordination and cooperation, make full use of their respective monitoring networks, closely monitor the development trend of meteorological, hydrological and geological disasters, establish information sharing and consultation mechanisms, make scientific and accurate analysis and judgment in time, and release geological disaster early warning and forecasting information through radio, television, newspapers, internet, telephone, mobile phone short messages and other channels.

Further improve the system of group monitoring and prevention of geological disasters. All localities should conscientiously implement the system of danger inspection, disaster quick report and duty in flood season, and comprehensively decompose the tasks of disaster prevention and avoidance, monitoring and early warning to towns, villages, schools, hospitals, enterprises and other units and relevant responsible personnel.

Strengthen duty and information reporting. City, county (city) people’s governments and competent departments should strengthen emergency duty, geological disaster emergency response agencies should implement a 24-hour duty and leadership shift system in accordance with the relevant provisions, and implement a main and deputy shift system for important positions. The person in charge of disaster prevention and emergency response personnel must keep their mobile phones on for 24 hours. Municipal geological disaster emergency teams should maintain a high degree of readiness and stand by at any time. It is necessary to make arrangements for the rotation of emergency personnel, ensure necessary transportation, emergency tools and emergency personnel, and ensure sufficient emergency forces to deal with sudden geological disasters at any time.

Strengthen the propaganda of geological disaster prevention knowledge. All localities should carry out targeted publicity in combination with local actual conditions and examples of ground disasters, especially to strengthen publicity for urban residents in mines and mountainous areas, cadres and masses in rural areas and primary and secondary school students, so that they can master the basic knowledge of preventing ground disasters.

Fully implement the responsibility for prevention and control of geological disasters. All localities and departments should conscientiously implement the Regulations on the Prevention and Control of Geological Disasters, and the natural resources departments should organize the implementation of various measures for the prevention and control of geological disasters, coordinate, guide and supervise all relevant responsible entities to do a good job in the prevention and control of geological disasters, and relevant departments such as construction, transportation, railway, water conservancy, meteorology, tourism and education should perform their respective duties according to law. All construction units shall design, construct and accept the ground disaster control project at the same time as the design and construction of the main project according to law, and take relevant measures in the construction process to avoid ground disasters.

　　August 19th is the first "China Physician’s Day", and 3.39 million medical practitioners in China have their own festivals. On this day, how did the majority of doctors live? Yesterday, the reporter visited some hospitals in this city and witnessed a special and ordinary day for doctors.

　　Location: Beijing Emergency Center Person: Wei Jian, 120 doctor on board.

　　It is an iron law to leave within two minutes.

　　Our reporter Wang Tianqi

　　In the morning, before 7: 30, Wei Jian, an emergency doctor, has been busy in the emergency equipment supply room of Beijing Emergency Center, checking whether the conventional first-aid items such as medicines, syringes and bandages in the first-aid kit are complete, whether the oxygen in the oxygen cylinder is sufficient, and whether the ventilator can be used normally … … "Stand by at any time, leave the car in two minutes, and all the preparations have to be done in advance." Wei Jian kept his hands and said without looking up.

　　Soon, the first departure instruction came: a lady near Beijing South Railway Station was unwell and had low blood pressure.

　　"Gao, we have everything. Let’s go!" Wei Jian picked up the first-aid kit and greeted Gao Shuo, the nurse accompanying the train crew. It took less than a minute from receiving the instruction to the ambulance opening the discharge door.

　　As soon as the ambulance drove to Qianmen West Street, it encountered a red light. Wei Jian was worried about the patient and wanted to make a phone call to ask about the situation. The instructions from the 120 receiving center came from the hand desk: "Just now, the patient at South Station called to return the car, saying that his blood pressure was not accurate before, but now it is much better. You should take a taxi to a nearby hospital yourself, so go back … …”

　　Wei Jian didn’t feel any displeasure after a trip in vain. "This kind of situation is very common. No matter whether the patient’s condition described by the train crew is critical or not when receiving the instruction, we must ensure that the train starts within two minutes. This is our ‘ Iron law ’ 。”

　　At 11 o’clock, in the canteen, Wei Jiangang put a spoonful of soup into the bowl. When the instruction came, he immediately put down the bowl and set off again.

　　The patient is an old man with headache, dizziness and high blood pressure, and he can’t get up. After getting on the ambulance, Wei Jianli dialed the phone number of the patient’s family from the newspaper receiving center. "Hello, we are 120 first aid, and we have already set off. Don’t worry, tell me about the patient’s condition first, whether there is a basic medical history, and whether you feel uncomfortable in the past few days?"

　　"The old man is very dizzy now, especially uncomfortable … … I fell yesterday and got two stitches … … There’s nothing wrong with it. I’m usually in good health … … Come on! " There was an anxious voice from the patient’s family on the phone. Wei Jian calmed his family members’ emotions, while continuing to ask about the specific situation of the elderly, and at the same time guiding his family members to keep the elderly lying flat and ventilated indoors.

　　Ten minutes later, the ambulance stopped under the residential building. Wei Jian jumped out of the ambulance, picked up the first-aid kit and rushed into the elevator, followed by the first-aid assistant pushing the hospital bed.

　　The old man was lying in bed, his head wrapped in gauze. Wei Jian leaned forward and whispered in the old man’s ear, "Can you hear me? Raise your left hand. " Seeing that the old man answered his words and made an accurate action, Wei Jian’s frowning brows relaxed a little, and hurriedly called the nurse to take the old man’s blood pressure. "The old man is conscious, so don’t be afraid." Wei Jian told the patient’s family that he had carefully inquired about the head injury. The family said that the old man fell down the day before because of dizziness and had a needle in his head. "That is still to get a CT from the hospital. Delayed cerebral hemorrhage may occur after head injury in the elderly."

　　After some examination, blood pressure and electrocardiogram were normal. Wei Jian found a stretcher and carried the old man to the hospital bed with his colleagues and family members. Before going downstairs, Wei Jian also carefully told the family members of the elderly, "Take cash and medical insurance cards and bring a plastic bag for fear that the elderly will feel dizzy and want to vomit."

　　I ran upstairs and downstairs twice, and Wei Jian, who was slightly fat, gasped. "In fact, this is already very good. I can still take an elevator. When I meet an old community, there is no elevator. There are many cases where patients are carried down on the sixth and seventh floors!"

　　When he arrived in xuanwu hospital, Wei Jian instructed his family members to register the old man, arranged the hospital bed, and handed over the old man’s condition to the resident one by one, so that Wei Jian’s first aid mission was completely completed.

　　By the time he got back to the emergency center, it was close to 12: 30, and the food prepared by his colleagues was already cold. Wei Jian wolfed it down and "solved the battle" in five minutes.

　　"Emergency doctors eat fast, because maybe the next second’s dispatch order will come again, just make up a bite at the place where the needle is inserted." WeiJian hey hey smile, round face, eyes bent into a crack. "When Dr. Wei came to the center, he was a thin guy, which was all stress obesity." Colleagues teased Wei Jian, who scratched his head. "I can’t help it. I work at night and my diet is irregular. I’m not fat."

　　Venue: Beijing Friendship Hospital Person: Li Zhenhua, an emergency doctor.

　　It is meaningful to spend the holidays in the emergency department.

　　Our reporter Ren Shan

　　"32 beds need to be observed after the rescue, and 2 beds and 3 beds need further treatment to see if they are transferred to cardiology." At 8 o’clock in the morning, the emergency room of Beijing Friendship Hospital was quiet for a while, and the night shift doctor quietly handed over the shift to Dr. Li Zhenhua.

　　Li Zhenhua is on the day shift, from 8 am to 8 pm. The first thing after taking over is to inspect the critically ill patients in the intensive care room.

　　"Are you still uncomfortable today? Did you sleep comfortably last night? " Bed 3 in the emergency room is an old lady who is over 80 years old. Due to atrial fibrillation (persistent arrhythmia), she suffered from bradycardia due to taking drugs for a long time. She suddenly lost her breath at home last Friday morning. After being rescued, her vital signs were stable, but her heart rate was still high and low.

　　Seeing the doctor coming, the old man’s daughter immediately leaned over.

　　"The old man’s heart rate is still slow. I suggest to transfer to CCU (Cardiac Intensive Care Unit). You didn’t seem willing before. What do you think now? " The family was still hesitating, and the old man in the hospital bed took Li Zhenhua’s hand. "Doctor, I listen to you."

　　After communicating with his family, Li Zhenhua hurried back to the nurses’ station to communicate the old man’s transfer to CCU. At this time, there was a sudden groan in the intensive care room, and Li Zhenhua ran to bed 32.

　　The old lady in bed 32 was curled up on the bed with intravenous drip. The old man was sent to the rescue two days before acute cerebral hemorrhage. Although he is out of danger and in stable condition, he is still very painful occasionally. "We want to transfer to a hospital near our home, and we don’t want to always run back and forth like this." Looking at the family members in the hospital bed, the family members made demands. "The condition is stable and can be transferred to hospital for treatment." Li Zhenhua said after the inspection.

　　I was still explaining here when suddenly a cry for help came: "Doctor, doctor, come and see my mother!" " An old lady was pushed into the emergency room.

　　"What disease?" "Acute cerebrovascular disease." "Is your mind still clear?" "Very clear." After a brief communication with the nurse, Li Zhenhua comforted his family. "Don’t worry, the neurologist will arrive soon, and arrange the hospital bed first." At this time, another doctor brought good news to Li Zhenhua. "The transfer of patients in bed 3 to CCU has been arranged."

　　Every day in the emergency room, like the morning of this battle, alternately staged sadness and joy.

　　After a round of rounds, 18 internal medicine patients spent nearly two hours in Li Zhenhua, and they also dealt with two sudden illnesses without drinking a mouthful of water. Li Zhenhua, who has worked in emergency for 18 years, has become accustomed to this pace of work.

　　Speaking of Physician’s Day, Li Zhenhua is also very happy. "This is the recognition of our society. It is meaningful to be able to spend the holidays in the emergency department during our festivals. "

　　At 11 o’clock noon, the family members of patients in the intensive care unit began to visit. Li Zhenhua returned to the doctor’s workstation and began to sort out the patient’s test results. Next, he will work with other doctors to make a diagnosis and treatment plan for each patient.

　　Venue: Capital Institute of Pediatrics Character: Li Qi, a pediatrician

　　The recovery and discharge of children is the most wanted gift.

　　Our reporter Liu Huan.

　　Less than 8 o’clock, in the surgical ward on the sixth floor of the inpatient building of the Capital Institute of Pediatrics, Li Hao, deputy chief physician of general (newborn) surgery, changed his white coat and hurried into the ward.

　　A day’s work began with the children crying one after another.

　　See the patient, prescribe the doctor’s advice, do the treatment, and even go to surgery at any time because of the sudden illness of the child … … On the same day, Li Qi and two other doctors were responsible for guarding more than 90 children in the ward.

　　"Doctor, please take a look at it for me. The child’s defecation after operation is not very good … …” At the door of the ward, a parent with a child in her arms blocked Li Wei and asked anxiously. "The anastomosis of the child’s anus is open. It should be that the wound is swollen, which leads to the passage of excrement … …” As he spoke, Li Hao took a syringe and injected the child with a few milliliters of medicine to promote intestinal peristalsis. "Look again for half an hour."

　　During the rounds, Li Jie’s cell phone rang from time to time. He communicated with his colleagues about the operation arrangement for a while, and then remotely instructed other medical staff to deal with various unexpected minor situations of the children.

　　Li Qi, 37, has been working in the First Children’s Hospital for 11 years. His specialty is pediatric surgery for intestinal diseases. "In our department, the vast majority of children admitted are concentrated in four major diseases: anal atresia, Hirschsprung’s disease, biliary atresia and choledochal cyst." Li Wei told reporters that these diseases that sound dangerous and abnormal are very common in pediatric surgery.

　　In Li Hao’s department, "white plus black" is the normal state of work, and it takes 24 hours or even longer to be on duty. At the busiest time, there are more than 20 operations a day in the general department, and it is common for one person to have five operations a day.

　　At 9: 40, Li Hao was called away by a phone call. In the neonatal internal medicine ward, a two-day-old child needs consultation because of lung malformation. For a whole hour, Li Hao and doctors from ultrasound, radiology, chest and other departments discussed countermeasures for the next treatment of children.

　　When waiting for the elevator, Li Hao, who took off her mask, showed a trace of fatigue on her face. In fact, Li Jie, who is on duty on weekends, and his wife and daughter at home have long been used to it. Li Wei said that it is basically a "big shot" for the family itself, and all the prostitutes who go to kindergarten are taken care of by their wives. The daughter said, "Dad should leave more time for other sick children." In his mobile phone, there are many photos of smiling children after recovery. Li Wei said that he owed a lot to his daughter, but when other children recovered and were discharged from the hospital, it was his most fulfilling moment. These were the gifts he most wanted to harvest on Physician’s Day.

　　In the afternoon, when the reporter left, Li Hao was once again "blocked" by the parents of the patients. On this big duty, he has been staring at 8 pm on August 20; And the next day, he will go to the surgery clinic for one day … …

　　BEIJING, June 30 (Reporter Zhang Xu) The new fire safety regulations for high-rise civil buildings are coming! It is related to the safety of the owners, and the maximum fine for seven acts is 10 thousand yuan. Look quickly!

　　Recently, the Order of the Emergency Management Department (No.5) was issued: "Regulations on Fire Safety Management of High-rise Civil Buildings" came into effect on August 1, 2021, clarifying that electric bicycles are prohibited in the corridors of high-rise civil buildings, and so on.

　　Keywords: "forbidden"

　　Fire safety must not be taken lightly, and prohibiting all kinds of unsafe behaviors is the top priority.

　　It is found that "prohibition" has become a high-frequency keyword in the Regulations on Fire Safety Management of High-rise Civil Buildings, and the full text has appeared 20 times in total.

　　Such as:

　　It is forbidden to install, modify or dismantle gas equipment and appliances without authorization in violation of the provisions on the safe use of gas.

　　Prohibit the use of liquefied petroleum gas in the underground part of high-rise civil buildings.

　　It is forbidden to produce, store and deal in Class A and Class B fire dangerous goods in high-rise civil buildings in violation of state regulations.

　　It is forbidden to occupy cable wells and pipe wells, or pile up sundries in vertical pipe wells such as cable wells and pipe wells.

　　It is forbidden to set obstacles that affect escape and fire fighting and rescue in the external windows of high-rise civil buildings.

　　It is forbidden to set up overhead pipelines, billboards, decorations and other obstacles that hinder the operation of fire engines above the passage of fire engines and on the climbing operation surface.

　　It is forbidden to park or charge electric bicycles in public halls, evacuation walkways, stairwells and safety exits of high-rise civil buildings..

　　… …

　　"No parking of battery cars in the corridor" has become popular.

　　After the publication of "Regulations on Fire Safety Management of High-rise Civil Buildings", it is forbidden to park battery cars in corridors, which has become the focus of network attention.

　　In recent years, due to irregular parking and charging and technical problems, battery car fires frequently occur, causing great losses to people’s lives and property safety. Since the beginning of this year, several fire incidents that occurred in the battery car upstairs have become hot topics, such as "five people were injured by fire in the elevator of the battery car" and so on.

　　It is forbidden to park or charge electric bicycles in public halls, evacuation walkways, stairwells and safety exits of high-rise civil buildings. How to park electric bicycles for residents? What about charging?

　　"Regulations on Fire Safety Management of High-rise Civil Buildings" proposes that:

　　"Encourage the establishment of centralized storage and charging places for electric bicycles in high-rise residential quarters. Electric bicycle storage and charging places should be set up independently and keep a safe distance from high-rise civil buildings; If it is really necessary to set it in a high-rise civil building, it should be separated from other parts of the building by fire prevention. "

　　"The storage and charging places of electric bicycles should be equipped with necessary fire-fighting equipment, and the charging facilities should have full automatic power-off function."

　　In order to ensure safety, there should be encouragement and punishment, and the Regulations on Fire Safety Management of High-rise Civil Buildings also clarifies the relevant legal responsibilities.

　　Seven kinds of behavior, the maximum fine of 10 thousand yuan.

　　According to the Regulations on Fire Safety Management of High-rise Civil Buildings:

　　(a) in high-rise civil buildings, electric welding, gas welding and other open flame operations, failing to perform hot work approval procedures, making an announcement, or failing to implement fire scene monitoring measures;

　　(2) Outdoor billboards and external decorations set up in high-rise civil buildings hinder smoke control, escape and fire fighting and rescue, or change or destroy the fire prevention structure of the building facade;

　　(three) the prompt and warning signs of the external wall insulation materials are not set, or the damaged, cracked and detached external wall insulation system is not repaired in time;

　　Fire safety should not be underestimated, so please pay attention to it. (End)

　　Eleven years ago, Jinshan’s performance declined after listing, and its share price kept falling. Qiu Bojun and Zhang Xuanlong, the founders of Jinshan, thought of Lei Jun who had left for three years. On that day, the three men took a group photo in front of Jinshan Software Building in Beijing. Since then, Qiu and Zhang retired, and Lei Jun took over as chairman of Jinshan.

　　Lei Jun’s task is to rebuild Jinshan, so that this China veteran software manufacturer can regain its vitality in generate. Mobile Internet is a powerful medicine given by Lei Jun to Jinshan. After some internal integration, Jinshan Cloud, the youngest business in Jinshan, has emerged. Lei Jun decided to let Jinshan take out all resources "All in cloud".

　　The darling of Jinshan Group, escorted by "Angel" Lei Jun, Jinshan Cloud can be regarded as a dream start. In May 2020, Jinshan Cloud landed on Nasdaq, but it didn’t take long for Jinshan Cloud to start falling. As of September 20th, Jinshan Cloud’s share price was $2.04/share, down 97.5% from the highest point of $74.76/share.

　　Jinshanyun’s market position fell in the third place in the industry and failed to keep the bottom line of Lei Jun’s "top three, at least top five". On the evening of September 6, Jinshan Cloud announced its financial report for the second quarter of fiscal year 2022. In the second quarter, Jinshan Cloud’s revenue was 1.906 billion yuan, down 12.3% year-on-year, which was the first quarterly revenue decline in recent years. The net loss was 811 million yuan, up 267.41% year-on-year.

　　Ten years of polished Jinshan cloud, but the blade has been exhausted. On July 27th, Jinshan Cloud submitted a prospectus for dual listing of Hong Kong stocks. On August 8th, Lei Jun announced that Wang Yulin, who had been in charge of Jinshan Cloud for nearly 10 years, resigned, and Zou Tao, a veteran of Jinshan, was appointed at the critical moment.

　　Jinshan Cloud, born out of Jinshan, naturally inherited the To B service gene. However, whether Jinshan Cloud can undertake the strategic task of rebuilding Jinshan and expand Lei Jun’s To B map depends on whether Jinshan Cloud can get out of the fog.

　　Jinshan Cloud reduces unprofitable CDN business.

　　According to the financial report, Jinshan Cloud’s revenue scale declined in the second quarter, and its performance was lower than expected, mainly because Jinshan Cloud continued to actively reduce CDN services. In addition, due to the epidemic situation in Beijing and Shanghai in the second quarter, Jinshan Cloud slowed down the bidding and project deployment process.

　　CDN business is the traditional advantage of Jinshan Cloud, which contributes most of the revenue of public cloud business. According to Jinshan Cloud’s US stock prospectus, its CDN business revenues from 2017 to 2019 were 629 million yuan, 1.161 billion yuan and 2.137 billion yuan, respectively, accounting for 52.2%, 54.9% and 61.9% of the revenue of public cloud products, far exceeding the computing and storage sectors in public cloud products.

　　It is worth noting that the advantages of Jinshan Cloud’s CDN business are more related to the previous price war of domestic cloud vendors. In December 2017, shortly after Jinshan Cloud announced the completion of the D round of $300 million financing, Jinshan Cloud would cut the price of mainstream products in an all-round way. This competition mode has also increased the degree of burning money in Jinshan Cloud, which is based on CDN business.

　　After listing, Jinshan Cloud slowly changed this situation. Jinshan Cloud revealed in the financial report that due to the general slowdown of the Internet industry in 2021, especially in the second half of 2021, the demand for CDN services in the whole year was lower than expected, resulting in redundant basic resources. In the fourth quarter of 2021, Jinshan Cloud took the initiative to reduce the scale of CDN services.

　　In the Q2 financial report of Jinshan Cloud, Jinshan Cloud’s public cloud business revenue was 1.289 billion yuan, a year-on-year decrease of 16.9%. Among them, the total billing volume of CDN services decreased by 30% year-on-year, and the total billing volume of computing and storage services increased by 5% year-on-year. However, the business segment of Jinshan Cloud still fell sharply.

　　Jinshan Cloud’s industry cloud service, which has been deeply cultivated in recent years, has also ended its high growth trend due to the epidemic and other reasons. In the second quarter, it achieved revenue of 617 million yuan, a year-on-year decrease of 0.9% and a slight year-on-year decrease.

　　

　　Source: Jinshan Cloud Q2 Financial Report

　　The effect of Jinshan Cloud on reducing the scale of CDN services is also reflected in the cost. In the second quarter, the revenue cost of Jinshan Cloud was 1.841 billion yuan, down 12.1% from 2.094 billion yuan in the first quarter and down 10.4% from 2.055 billion yuan in the same period in 2021.

　　Reducing CDN business is Jinshan Cloud’s initiative to change the situation of increasing revenue but not increasing profit, which coincides with Jinshan Cloud’s three propositions of succeeding CEO Zou Tao: first, establish technology-oriented business to continuously improve the company’s scalable core technologies and products; The second is to drive sales with solutions, providing easy-to-access and practical cloud application value for traditional enterprises in China; Third, adhere to neutrality and become one of the most trusted cloud service providers in the industry.

　　Losses are a necessary stage in the development of cloud computing vendors. Jinshan Cloud can’t escape the process of burning money, but it is also a necessary way to continue to expand its scale to share the cost pressure.

　　Relying on the ecological support of Jinshan and Xiaomi, Jinshan Cloud was at the head of the industry in the early stage of development. Giants continue to scramble for land, and Jinshan Cloud has retreated to the second-line position in the fierce market competition. According to the revenue in 2021, the top three cloud service providers in China are Alibaba Cloud, Tencent Cloud and Huawei Cloud, with a total market share of 42.7%. Although Jinshan Cloud ranks fourth, the third place is more than twice as much as it, so it has to stand in the second echelon with other manufacturers.

　　Jinshan Cloud is still maintaining the rhythm of loss when its market position declines. Jinshan Cloud relied on the price war a few years ago and did not go out in the melee of cloud manufacturers, but it also caused huge losses in Jinshan Cloud for years. From 2019 to 2021, Jinshan Cloud’s revenue scale increased from 3.956 billion yuan to 9.061 billion yuan, and its net loss also increased from 1.111 billion yuan to 1.592 billion yuan.

　　However, Jinshan Cloud’s falling behind has long been traceable. According to the prospectus, from 2019 to 2021, Jinshan Cloud’s revenue grew at a compound annual growth rate of 51.3%. Among them, in 2020 and 2021, the revenue growth rate of Jinshan Cloud was 66.2% and 37.8% respectively. In the first quarter of 2022, Jinshan Cloud’s revenue was 2.173 billion yuan, up only 19.9% year-on-year, and it also declined in the second quarter.

　　Independent cloud vendors relying on Jinshan and Xiaomi ecology

　　The growth of Jinshan Cloud is inseparable from the support of shareholders Lei Jun, Jinshan and Xiaomi.

　　According to the prospectus, Jinshan Software, Xiaomi and Lei Jun are the major shareholders of Jinshan Cloud, holding 37.40%, 11.82% and 11.82% respectively.

　　

　　Source: Jinshan Yungang Stock Prospectus

　　Jinshan Cloud and its shareholders Jinshan Software Group and Xiaomi have formed a business synergy. Jinshan Cloud provides cloud solutions to Jinshan Software Group, and can also take advantage of Jinshan Software Group’s sales network through cross-selling opportunities. Jinshan’s Xishanju game business also adopts Jinshan Cloud’s services.

　　Jinshan Cloud provided cloud storage services to Xiaomi in 2013. In addition, Xiaomi is a world-renowned consumer electronics manufacturer, with a large number of terminal equipment users, such a large-scale terminal connection, massive user consumption and behavior data, as well as shopping, content, etc., all of which need a strong cloud computing infrastructure to carry. Jinshan Cloud can cooperate with Xiaomi and its ecosystem participants to develop cloud solutions in emerging industries.

　　Based on this relationship, in 2019, 2020, 2021 and the first three months of 2022, Jinshan Cloud’s income from Jinshan Software Group accounted for 2.8%, 1.8%, 1.7% and 2.2% of the total income, and the income from Xiaomi accounted for 14.4%, 10.0%, 8.5% and 10.9% of the total income respectively.

　　Jinshan Cloud has been implementing the strategy of mass customization. According to the prospectus, from 2019 to 2021, the top five customers of Jinshan Cloud contributed 65.7%, 61.5% and 50.5% of revenue to Jinshan Cloud respectively, of which most were Internet companies, and most of them purchased public cloud services.

　　However, large customers do not necessarily choose Jinshan Cloud firmly. In recent years, enterprises have begun to pursue cloudy deployment, that is, they have chosen a number of cloud vendors to provide services. As far as Xiaomi himself is concerned, at least two clouds can support the smooth operation of his business. Jinshan Cloud, as Xiaomi’s own product, is naturally the first choice, but in addition to Jinshan Cloud, Xiaomi also chose Microsoft Azure, the second cloud vendor.

　　For the same reason, other big customers of Jinshan Cloud also have the possibility of "changing their minds". ByteDance used to be Jinshan Cloud’s biggest customer. However, as ByteDance started to operate its own cloud services, its services using Jinshan Cloud will gradually decrease. What’s more, Jinshan Cloud has a strong competitor in the cloud service market.

　　Wang Yulin left, and Zou Tao was on the verge of death.

　　Lei Jun can be regarded as one of the earliest entrepreneurs who pay attention to cloud computing in China. Jinshan Cloud has been established for 10 years, and Lei Jun once compared Jinshan Cloud to the future of Jinshan.

　　However, Lei Jun’s current task is on Xiaomi Automobile. After the establishment of Jinshan Cloud, apart from investment and business collaboration between Jinshan Cloud and Xiaomi, Lei Jun does not dominate the daily operation of Jinshan Cloud. According to media reports, employees inside Jinshan Cloud believe that although Lei Jun talks about All in cloud computing, he actually doesn’t pay much attention to Jinshan Cloud and doesn’t pay enough attention to it.

　　On August 8th, Lei Jun, as the chairman of Jinshan Cloud, published an open letter to all colleagues of Jinshan Cloud, announcing that Wang Yulin, CEO of Jinshan Cloud, had submitted his resignation report for personal health reasons, and Zou Tao, director and vice chairman of the company, was appointed as the acting CEO.

　　Wang Yulin joined Jinshan Cloud in January 2013 and worked for nearly 10 years. He witnessed the development of Jinshan Cloud and the listing of US stocks. He is a man of the hour in China’s cloud computing market, but he also left a lagging Jinshan Cloud for Lei Jun, making Lei Jun’s once brave words an embarrassing flag.

　　So, Zou Tao’s succession, then some of the crisis. It is understood that Zou Tao joined Jinshan in 1998, when Lei Jun just became the general manager of Jinshan. Zou Tao is the former senior vice president of Jinshan Software and CEO of Xishanju Games. The most memorable career in Jinshan is Sword Net 3. In 2004, Jinshan planned to make a martial arts RPG game and invested a lot of resources. Five years later, Jianwang 3 was released in the expectation of everyone. Unexpectedly, for the first time, the response of Jianwang 3 was flat, just as Lei Jun said, "it was a mess".

　　That time was the critical moment of Jinshan Game. Zou Tao stood up to support Jianwang 3 and changed the game from 2009 to 2011, and Jianwang 300 was turned into steel. Since 2012, Jianwang 3 has doubled its income for many years in a row, becoming Jinshan’s largest source of income and profit.

　　This time is the critical moment of Jinshan Cloud. As an old Jinshan person, Zou Tao has more sense of mission. However, in the face of the transition moment, the three value propositions mentioned by Zou Tao need to be verified. Wang Yulin believes that cloud computing is a long-distance running business, and it is not certain who can overtake it. Is there any chance for Jinshan Cloud to rise again before it hits the bottom?

　　At this stage, Jinshan Cloud’s breakthrough lies in opening up more markets, but what lies ahead is the crazy division of territory by industry giants in various fields. Zou Tao, CEO of Jinshan Cloud, revealed in the Q2 earnings conference call that in the face of the giants, Jinshan Cloud may continue to deepen its cultivation in some original fields and make its own differentiation, such as medical care and finance, before it has the opportunity to replicate its successful experience to other industries.

　　In the past ten years, Jinshan Cloud has provided the underlying cloud services for Xiaomi and Jinshan, but Lei Jun doesn’t want Jinshan Cloud to be just a "tool person" for Xiaomi and Jinshan. To establish the setting of independent cloud vendors, Jinshan Cloud should open up a pure cloud service model in the cloud computing market, which may be the future of Jinshan that Lei Jun wants to build.

With the progress of social civilization, we can see that many high-tech technologies have been applied to mass-produced vehicles, and the driving experience of consumers has been improved, which is highly playable. What we said today. Let’s take a look at it next.

Let’s take a look at the appearance of Ford electric horse. The head of Ford electric horse adopts a very concise design, which looks more fashionable and dynamic. Coupled with the steady headlights, it is the finishing touch on the front face. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4730MM*1886MM*1613MM. The car adopts spiritual lines, and the side wall feels very full. With large-sized thick-walled tires, smooth lines run through the whole car side. In the design of the rear end, the rear end looks simple, and the taillights present a dignified design style, creating a good gas field.

Sitting in the car, the interior looks very young and meets the aesthetic standards of young people. The steering wheel of the car is well designed, made of leather and has a good visual effect. Let’s take a look at the central control, with a 15.5-inch central control screen, which makes the interior style impressive and gives people a feeling of being domineering and stylish. The dashboard and seats give people a good feeling, too. Let’s take a look. The dashboard of this car presents a fierce design style, which is very eye-catching. The car adopts imitation leather seats, which are spacious and thick, with exquisite materials and comfortable ride.

To sum up: I wonder if you are excited about this car introduced today?

It is no exaggeration to say that the two most tonal car brands within the 300,000, one is BMW and the other is Mercedes-Benz Smart.

In fact, many small partners usually consider these two car brands when buying a car. So which of these two car companies’ electric cars is more original? In fact, looking at the Mercedes-Benz smart series, it is difficult to find the design of the previous small hatchback, but it is getting bigger and bigger. After all, Mercedes-Benz smart has also been discontinued for a time. With the advent of the electrification era, although it has been revived, it is basically not very similar to the previous fuel version.

In contrast, BMW’s electric MINI, although it has been electrified, many details are still designed to move closer to fuel vehicles, such as still having"Play Limit"The mechanical design of this machine offers better handling properties.

Now the starting price of the electric MINI COOPER has come to 148,800, such a price is after the price reduction, because the original price of 209,800 yuan.

Of course, after actual understanding, the entry-level model has no existing car, and needs to be installed to a certain extent, and most users install a 10-speaker Harman card stereo. The advantage of the installation is that the invoice price exceeds 150,000 yuan, so you can enjoy a large policy subsidy (generally more than 150,000 yuan subsidy is higher). For users, in fact, they did not pay more, but enjoyed a better configuration.

From the power system point of view, the electric MINI COOPER adopts a single motor front drive design, with a maximum power of 135 kilowatts and a peak torque of 290N · m. Of course, if you buy a medium and high configuration model, the power of the motor reaches 160kW and the peak torque is 330N · m, the performance is still very strong, and the battery life of the whole vehicle exceeds 450km, and the whole system has fast charging function. So whether it is a daily commute to get off work or a long-distance outing, there is no problem.

The exterior design is still original and retains the familiar BMW MINI family design, so I think even the electric version of the BMW MINIi is also worth choosing. In addition, the two-color appearance, round retro headlights are very comprehensive, and it is standard with 18-inch wheels, which is extremely kind.

We are also very familiar with the interior design, featuring a circular LED large-screen design, a three-frame multi-function leather steering wheel, leather seats with a circular angle, and an electric sunroof on mid-to-high-end models.

Of course, as for some classic elements, such as frameless doors, environmentally friendly fabric interiors, and the pushover of aircraft buttons, we can also choose intelligent driver assistance systems, making it easier to go out and drive.

Although 148,800 is actually not easy to buy our new car, but even after the installation is still particularly advantageous, the price has not become too expensive. 10 Harman card stereo, plus the removal of the country after the price of the naked car, really fragrant, do not need to pay the purchase tax, landing is very advantageous.

In fact, some people only know that the BMW MINI has a personality and tone. In fact, the value preservation of the BMW MINI actually exceeds that of the BMW, which is not clear to many people. Compared with the BMW MINI R56 of the same year and the same price, the residual value of the BMW MINI R56 used car is much higher. It can be seen that whether it is a new or used car, the BMW MINI is very popular.

　　[Pacific Auto] In 2023, the brand-new domestic (|) long version and i5 pure electric version were officially unveiled. The new car adopted a brand-new design language, the appearance and interior were greatly improved compared with the current models, the body size was further strengthened, the power was also improved, and the comprehensive strength rose to a new dimension.

　　In terms of appearance, the new car continues the design of overseas models as a whole, and the style is relatively conservative. The front face does not adopt the longitudinal kidney grille of the 4 series, nor does it adopt the design of the "squint" split headlights of the 7 series. Instead, based on the current model, the headlight group and the front surround have been adjusted, which is the right direction. After all, the appearance of the current 5 Series is very successful, and there is no need to make drastic adjustments.

　　On the side of the car body, the bright logo of "5" was designed at the corner of Hoxhorn, while the hidden door handle was designed, and a new style of wheel hub was replaced. The wheel hub size was available in 19 inches and 20 inches, which greatly improved the recognition and advanced feeling of the new car.

It is equipped with a 12.3-inch LCD instrument+a 14.9-inch touch screen to form a joint screen design, built-in iDrive 8.5 car system, and the air-conditioning outlet adopts a hidden layout, and the physical buttons in the original air-conditioning area are greatly reduced to touch operation, plus it is equipped with an encircling interactive light strip, which is both scientific and luxurious.

　　In addition, in order to meet the riding needs of Chinese people, the rear seat of the new domestic BMW 5 Series has been upgraded. The rear seat of the new car has not only been lengthened and thickened, but also a comfortable soft pillow has been customized for the front seat for the first time, and the exclusive logo of the word "five" is printed on the backrest of the front seat, further strengthening the special identity of China.

　　At the same time, the suspended giant screen launched by the BMW 7 Series will also become the exclusive option of the domestic long-wheelbase version of the 5 Series, with the characteristics of 8K, 31-inch and real-time interconnection. This configuration is not carried in the overseas version of the 5 Series. It can be seen that in order to please China users, BMW has specially equipped the configuration that meets the needs of Chinese people, which will also redefine the luxury.

　　In terms of power, according to the application information, the new BMW 525Li is equipped with a low weight of 2.0T, 156kW (212hp) and a top speed of 225km/h; The new BMW 530Li is equipped with a high-power 2.0T engine with a maximum power of 211kW (287HP) and a top speed of 250km/h..

　　As for the (|) eDrive 35L model, it is equipped with a motor with a maximum power of 250 kW (340 HP) and a top speed of 190km/h, which is consistent with the eDrive 40L model. The battery life information is unknown at present. For reference, BMW i3 eDrive 40L is equipped with a 79.05 kWh battery pack, and the battery life under CLTC condition is 592km.

　　In addition, it is worth mentioning that, according to the official introduction of BMW, in terms of driving control and chassis, in order to better balance sportiness and long-distance comfort, the new BMW 5 Series has increased front and rear axles, nearly 50:50 axle load distribution ratio, intelligent structure and enhanced connection stiffness between the body and chassis.

The picture shows the current BMW 5 Series.

　　In terms of price, as a reference, the price range of the current domestic BMW 5 Series is 43.65-56.25 million, the terminal market discount is more than 80,000 yuan, and the entry-level model is less than 400,000 yuan, which is extremely cost-effective. The new BMW 5 Series has been upgraded in many aspects. It is expected that the price will be adjusted, and there will not be many discounts in the short term after listing. If you want to pursue cost performance and are not too interested in the design of the new BMW 5 Series, it may be a better choice to bargain-hunting the cash model now. (Text: Pacific Auto Wu Qi)

Two days ago, several fans in the fan group had a heated discussion about which smart pure electric car to choose, and the brands they supported were also diverse, from appearance to practicality, from product parameters to technical indicators, until a fan friend said: "If you want me to say, if you choose smart pure electric, you still have to choose the new energy national team, which is the same reason that car companies choose two barrels of oil when choosing a power exchange partner."
