　　With the development of science and technology, a new round of scientific, technological and industrial revolution triggered by artificial intelligence will have a sustained, extensive and profound impact on China’s employment. Under the progress of artificial intelligence technology, how to fully implement the "employment priority" policy and achieve higher quality employment has become an important issue of "protecting people’s livelihood".

　　First, choose the "employment first" intelligent transformation development model

　　Different from the previous three technological revolutions, the technological progress of artificial intelligence has a stronger effect on empowering enterprises, improving quality and reducing costs, and increasing benefits, and has a more obvious effect on the multiplier effect of man-machine complementarity, the enhancement of workers’ ability and the improvement of employment quality. Therefore, it is necessary to speed up the formulation of tax relief and financial subsidy incentive policies to promote the rapid application of artificial intelligence technology in new scenarios and traditional industries, create benefit sharing among stakeholders in the value chain, create a win-win space for all parties, and reduce obstacles to the application of new technologies. On the one hand, it forces technological innovation through landing application, and improves the usability and ease of use of technology. On the other hand, it promotes industrial intelligence through landing application, which promotes the expansion of employment and the improvement of employment quality, and then realizes the triple spiral of "intelligent industrialization, industrial intelligence and employment expansion".

　　In the strategic layout of artificial intelligence, the "dual" development model of vertical whole industrial chain cluster development and horizontal related industrial chains driven development is implemented, and employment is given priority, and a matrix employment priority strategy is established. On the one hand, the vertical whole industrial chain promotes employment as a whole, on the other hand, the horizontal related industries promote employment. Taking the intelligent driving industry as an example, its industrial chain includes vehicle manufacturing enterprises, large Internet enterprises, small intelligent driving innovation and entrepreneurship enterprises, service supporting enterprises and public departments. In the vertical direction, a vertical industry chain-driven employment model of "stable employment of large vehicle manufacturing enterprises+employment absorption of large Internet enterprises+creation of new jobs by small intelligent driving innovation and entrepreneurship enterprises, service supporting enterprises and public service departments" can be formed. In the horizontal direction, the application of intelligent driving technology in other industries can be used to promote employment. For example, the application in agriculture, mining, ports, urban transportation and other fields will drive employment horizontally.

　　In addition, support the emergence of new forms and models of artificial intelligence in new infrastructure, new scenes and industrial applications, such as a large number of data annotator jobs created by artificial intelligence basic data industrial bases in new infrastructure; Small-scale intelligent driving innovation and entrepreneurship enterprises that appear in the automatic driving application scenario include core sensor research and development, chip research and development, key algorithm research and development, emerging car-making enterprises and other technological innovation enterprises, start-ups and new business enterprises. It is necessary to encourage the development of these new forms and modes of enterprises, open up new employment space and enhance employment tension. At the same time, under the new development pattern that the domestic big cycle is the main body and the domestic and international double cycles promote each other, we will promote the intelligent transformation of the global supply chain and promote offshore outsourcing employment and the return of overseas returnees.

　　Second, activate the domestic consumer market and expand new foreign consumer markets

　　Employment is an induced demand. To expand employment, it is necessary to expand employment through the expansion of demand for products and services. With the application of artificial intelligence technologies such as computer vision, natural language processing, speech recognition, human-computer interaction, machine learning, knowledge map, biometric identification, virtual reality or augmented reality in products, enterprises will develop more new products and create more intelligent services according to market demand. Therefore, policies to expand the consumption of artificial intelligence products and services should be introduced as soon as possible. The second is to introduce policies to encourage the expansion of artificial intelligence to drive the consumption of industrial products and services. The application of artificial intelligence in different scenarios will change the whole social ecology, and a large number of new products and services will be created in this process. The third is to create new demands, promote new consumption to lead a new quality life, foster new intelligent employment forms and employment patterns, and promote diversified investment, so as to form a strong domestic artificial intelligence product and service market and better meet people’s new expectations for a better life in an intelligent society. Fourth, make use of the first-Mover advantage of China’s artificial intelligence in the application field, innovate more artificial intelligence products and services suitable for the international consumer market, formulate export incentive policies for artificial intelligence technologies, products and services, and smooth and expand the international market.

　　Third, create the expansion work "based on unique human skills"

　　The advantage of artificial intelligence is to discover laws from a large number of data, especially unstructured data, and help humans to complete repetitive and standardized work that can make decisions only by simple thinking. In terms of quantifiable and standardized programs, artificial intelligence is better than human beings. However, human beings have the uniqueness of thinking, creation, communication, emotional communication, cooperative spirit, curiosity, enthusiasm, like-minded driving force, emotion, understanding of good and evil, understanding of beauty and ugliness, and are better at engaging in creative work. Artificial intelligence and human beings are good at each other. It is expected that artificial intelligence will quickly occupy many standardization fields in the future, and human beings will find new areas of expertise in the supply of various differentiated and personalized products and services. According to the comparative advantages of man and machine mentioned above, the "people-oriented" work fields that human beings may expand in the future include: nursing work for the elderly, the infirm and the mentally ill; Basic education and special education; Experience economy work that serves individual needs; Handicrafts that meet the creative needs of young people, creative economy jobs such as VRMR game experience, etc., in addition, some new occupations have emerged, such as data annotator, intelligent manufacturing engineer, virtual reality engineer, artificial intelligence trainer, artificial intelligence trainer, drone assembly and adjustment worker, etc. The government should promptly formulate incentive policies to encourage society to create expansion jobs based on unique human skills.

　　Fourth, encourage non-standardization work in the process of intelligence.

　　The progress of artificial intelligence technology brings new employment forms, organizational forms and working methods. Non-standard employment is an inestimable field to absorb unemployed workers, which represents the originality and adaptability of the labor force. Develop a variety of non-standardized flexible employment methods to appropriately alleviate the employment pressure, increase the flexibility of the labor market, and meet the employment needs of different labor groups. At present, the flexible employment modes of international concern mainly include: part-time employment, short-term employment, dispatched employment, seasonal employment, standby employment, part-time employment, remote employment, contracted employment, independent employment, self-employment and family employment. In addition, in order to reduce the unemployment risk of artificial intelligence technology and alleviate inequality, we should choose to introduce active labor market policies, such as job incentives and employment assistance, so as to provide solutions for the surplus of low-skilled labor. The public sector or social organizations should indirectly provide employment opportunities for the unemployed, including temporary posts or short-term skills training courses. At the same time, workers should take the initiative to embrace new technology, use technology to find new opportunities, make up for the shortage of full-time jobs by engaging in freelance and part-time jobs, and alleviate the labor market tension caused by technological unemployment.

　　Secondly, with the application of artificial intelligence technology in digital platform, a large number of new employment forms, such as live broadcast, online literature, intelligent scene experience, etc., are often not fully covered by the current formal social security system, so the government’s social security supporting policies should be matched with it, so that the new non-standardized work brought by artificial intelligence can bring higher income level, freedom, satisfaction and happiness to workers, thus achieving higher quality employment.

　　Finally, we can consider using artificial intelligence technology to establish a flexible employment platform for digital talent supply and demand. Accurate matching through big data can reduce job search time, loosen restrictions on the free flow of talents and data, and provide free data to help workers find new opportunities, stimulate innovation and improve economic efficiency.

　　Cctv news(Reporter Gao Yuting) Shortly after returning to Ningxia, yan hou, a Party representative, began to preach the spirit of the 19th National Congress. On the morning of November 1st, yan hou was invited by Ningxia Committee of the Communist Youth League to preach the spirit of the 19th National Congress for young people from all ethnic groups and walks of life in the autonomous region. This was her first lecture after her return.

Yan hou was invited by Ningxia Communist Youth League to preach the spirit of the 19th National Congress for young people from all walks of life in the region.

　　The theme of this lecture is "to be a great national rejuvenation and a new youth in the new era". "Being worthy of a great post" is not only yan hou’s message to young people, but also her own words in the cultural inheritance and development of Shaanxi Opera.

　　Yan hou is the deputy general manager of Shaanxi Opera Theatre Co., Ltd. of Ningxia Performing Arts Group, and has won the Plum Blossom Award, the highest drama award in China. The achievement of these achievements, in her own words, is persistence, family inheritance and responsibility for opera.

　　When preaching, yan hou repeatedly mentioned the cultural self-confidence in the report of the 19th National Congress. She was deeply touched by this: "Speaking of cultural self-confidence, as a grassroots representative, I was deeply touched. When the opera was in recession in the 1990s, I didn’t even dare to mention my own industry."

　　In the early 1990s, when the theater was demolished, she opened a clothing store to sell clothes. But during the time when she opened a clothing store, there were even farmers who had heard her singing, and they inquired about her clothing store and came to see her. So, yan hou stood in the shop and sang some songs to the old man.

　　This incident has moved yan hou to this day. It was her mother, who put yan hou on the stage, who was also a Shaanxi opera actor. Besides her mother, it was the farmers’ "fans" who kept Hou Yanjian on the stage of opera.

　　Yan hou, who has no chance to play, can only take movies and TV series outside, and then use the money he earned to buy Shaanxi opera costumes and find a better Shaanxi opera teacher to learn opera.

　　"Slowly, with the opera ‘ Hundreds of townships and thousands of games ’ 、‘ Performance of traditional Chinese opera benefiting the people ’ ‘ Opera enters the campus ’ … … The good policies of the party and the government on opera have been introduced one after another. We have undergone earth-shaking changes from the beginning of no drama to the present drama. " Yan hou regrets.

　　Ningxia Shaanxi Opera Theatre has more than 400 performances a year, of which 180 are in rural areas and at the grassroots level. Yan hou will take part in more than 400 performances whenever he has time. For more than 20 years, she has not only visited all the towns and villages in Ningxia, but some even visited many times.

　　"Now 606 poverty-stricken villages in Ningxia have built comprehensive cultural service centers. The roads in some villages are too narrow for caravans to enter. If the car can’t get in, there will be no stage, and the wear and tear of costume props will not be enough for the audience. Now that we have a stage, they can entertain themselves after we leave, which is different. " Yan hou said that over the past 20 years, she has witnessed not only the development of Shaanxi opera, but also the construction and development of new countryside and its cultural undertakings in Ningxia.

Yan hou carefully prepares the stage makeup (provided by yan hou)

　　Preaching and preaching. On the afternoon of November 1st, after the morning lecture, Hou Yan rushed to Pingluo County, which is more than 50 kilometers away from Yinchuan City, in Jin Shun Community, Chengguan Town, Pingluo County. This time, the theme of her lecture was "Tell the story of the people more simply and forcefully".

　　Hou Yan once again mentioned cultural self-confidence: "Regarding cultural construction, the seventh part of the report proposes to strengthen cultural self-confidence and promote the prosperity of socialist culture. The report pointed out that without a high degree of cultural self-confidence and cultural prosperity, there would be no great rejuvenation of the Chinese nation. "

　　"As a literary and art worker, in any era, our masterpieces of literature and art should show people’s living conditions and people’s spiritual world, and adhere to the creative direction of serving the people. This is the first and most important value pursuit of literary and art workers. Literary and artistic creation leaves the people, just as fish leaves water and trees leave the soil, life will lose its foundation and fall into exhaustion. "

The residents of Jin Shun community came here and were very happy to hear yan hou sing two songs.

　　After the lecture, many residents in the community came here, asking yan hou to sing two Shaanxi opera for everyone. As soon as Hou Yan raised her voice, the eyes of the aunts and grandmothers in the room lit up, and they took out their mobile phones to take photos and take photos as a souvenir. After yan hou’s singing, there were Shaanxi opera lovers who came out to ask for advice on Shaanxi opera singing.

　　As far as yan hou is concerned, as long as there are people in the audience who love to watch the theatre and are happy and festive, she will feel happy and worthwhile, and she is willing to perform on this stage forever.

　　On August 8, the 29th Summer Olympic Games opened at the Beijing National Stadium, and gorgeous fireworks reflected the night sky in Beijing. China News Agency issued Wang Dongming photo

　　China News Service, August 8 th: The Secret of the "Bird’s Nest" Fireworks (I): Look at how the peony blooms.

　　China News Service reporter Wu Qingcai

　　At the opening ceremony of the Beijing Olympic Games tonight, red peonies are in full bloom over the "Bird’s Nest", and there are many strange shapes such as the Olympic rings and the dove of peace. So, how on earth are the peonies blooming over the Bird’s Nest?

　　Zhao Weiping, the commander-in-chief of the "Bird’s Nest" and the Great Wall fireworks display team at the opening and closing ceremonies of the Beijing Olympic Games, revealed to our reporter the secrets of the seven classic shapes of fireworks that night.

　　The First Classic Modeling-How Peony Blooms

　　The first climax of the "Bird’s Nest" is to interpret the whole process of peony, the national flower, from budding to blooming, and suddenly the Bird’s Nest turns into a red ocean of peony. From the blossoming of flowers and bones to the "relay" opening of petals, and then to the blooming of peony, the blooming process of "peony blossom" took only eleven seconds, but the number of fireworks was 4,845.

　　Zhao Weiping, chairman of the national brand Panda Fireworks Company, said that in order to make the whole red peony cover the whole bird’s nest, the "Peony Blossom" was set off all the steel frames at the top of the bird’s nest and the upper edge of the bowl of the bird’s nest. In order to choose the right color and fully show the elegance and wealth of peony, the designers of Panda Fireworks screened dozens of schemes and finally chose a peach red.

　　Using the three-dimensional special effects of the computer, the designer drew a huge peony covering the roof of the "Bird’s Nest", and then selected 85 points on the roof of the "Bird’s Nest", each of which was responsible for emitting three petals, each of which was composed of 29 fireworks, symbolizing the 29th Olympic Games.

　　"Eighty-five points have different inclination angles, so as to draw a peony flower that is natural." Zhao Weiping said that when setting off, the "flower heart" was emitted from the inside to the outside, and then the innermost "petal" was emitted, which in turn went over to the outermost petal. When the last petal was opened, 85 points were started at the same time, and fireworks were fired in unison, forming a big peony with bright red and unrestrained enthusiasm.

　　The Second Classic Modeling ―― Turning out the "Olympic Five Rings"

　　That night, five circles of five colors, red, yellow, green, black and basket, appeared in the sky, and the five circles were connected with each other, showing the Olympic rings pattern.

　　"Playing the Olympic rings pattern, some Olympic host cities also had this idea, but it didn’t work out." Zhao Weiping told reporters: The biggest difficulty in displaying the Olympic rings and other patterns with fireworks is that the initiation point and time interval of fireworks are difficult to control. The interval error of each fireworks is less than 0.03 seconds, and the audience can see the circle and the five rings only when they are fired in series at a constant speed. Finally, under the guarantee of new scientific research technologies such as air launch and chip fireworks, the global problem of depicting the Olympic rings with fireworks was completely solved by China fireworks people.

　　The Third Classic Modeling ―― "Silver Waterfall" Flows into the Stand

　　During the opening ceremony, there was a "silver waterfall" nearly 40 meters long, like the Milky Way, which slowly hung down along the bowl of the "Bird’s Nest" and flowed into the stadium. The "Bird’s Nest" stand immediately turned into a silver hall. Fireworks exploded around, but the audience couldn’t smell a trace of sulfur, and there was no worry about sparks.

　　Zhao Weiping said that the diameter of the bowl of the "Bird’s Nest" is about 500 meters, which is more than 40 meters above the ground. This shape requires that the diameter of the "Silver Waterfall" should not be less than 500 meters and the length should not be less than 30 meters, otherwise, the audience will not be able to be there. In order to realize this idea, Panda Fireworks Man has broken through four major problems: environmental protection, safety, tasteless, discharge, quick installation and quick disassembly.

　　The Fourth Classic Modeling ―― "Dove of Peace" Bird’s Nest "Spreading Wings"

　　Careful viewers will find that a pair of snow-white wings were born on both sides of the "Bird’s Nest", flapping up and down, just like a dove spreading its wings and flying.

　　Zhao Weiping told reporters that it is not difficult for the "Bird’s Nest" to give birth to "wings". What is difficult is that the wings should be flapped up and down, showing a dove of peace spreading its wings and flying dynamically. In order to make this dove of peace "smart", the researchers first improved the discharge effect of the traditional fireworks element "white tail", which has only white light and no track left by the tail passing through the air, just like the wings of the dove of peace. In order to make the wings move, the researchers calculated the flapping frequency of the flying dove of peace, so that the "Bird’s Nest dove of peace" fluttered its wings once a second on average.

　　The Fifth Classic Modeling ―― Dynamic World of "Red Flash Bird’s Nest"

　　Its modeling features are as follows: a red silk thread runs through the "Bird’s Nest" as red neon lights keep flashing, and under its embellishment, the whole "Bird’s Nest"

　　"In the flashing, running, jumping.

　　Zhao Weiping said that the first difficulty of the "Red Flash Bird’s Nest" lies in the layout. In order to cover the entire "Bird’s Nest", a launching point should be set up every five meters on each main beam; At the junction of the two main beams, a launching point is also set up every five meters, and all launching points are evenly distributed, so that the whole "Bird’s Nest" can jump in the red ocean; The second difficulty lies in the time difference control, and the fireworks at each point must be lit and extinguished at the same time.

　　The Sixth Classic Modeling ―― "Opening the Tianmen"

　　Its modeling features are: a resplendent arched gate, which appears over the "Bird’s Nest". From closing the door and opening a crack to opening half and three quarters until the Golden Gate finally opens.

　　Zhao Weiping said, "Opening the Tianmen Gate" is difficult to measure in the distance and angle between the ground and air. The distance between the first group of emission points and the angle with the horizontal plane must ensure that the emitted fireworks meet in the air and hand over an arch shape; The distance and horizontal angle between the second group of fireworks must ensure that when the fireworks meet in the air, there is just a gap, just like the door has just opened a gap, and so on, until the Golden Gate opens, the angle is a little off, so the process of opening the door cannot be vividly reproduced.　　

　　The Seventh Classic Modeling-"Countdown" Entering "Olympic Time and Space"

　　9, 8, 7 … At the opening ceremony of the Olympic Games, the first thing that appeared in the air was flashing numbers, which sent a strong signal in fireworks language: the Olympic Games is near! Zhao Weiping introduced that the number nine drawn with fireworks stays in the air for no less than one second. As soon as the number nine goes out, it lights up at eight and flashes again for one second. "If any number stays even in the blink of an eye, the fireworks will not draw a countdown stopwatch, which is synchronized with the stopwatch and does not allow any error.".

New Hainan Client, Nanhai Net December 19 news (Reporter Fu Caiyun) The film industry and green and low carbon, two concepts that seem to be far apart, will have a huge spark when they collide. On the 19th, the 5th Hainan Island International Film Festival-Green Zero-carbon Development Forum of Film Production Industrialization was held, and film creators, film and television base managers and new energy technology companies were invited to gather together to discuss the inefficiency, waste and serious pollution of traditional film production, and try to provide new solutions to the problems.

The film industry is a "spotlight industry" that attracts public attention. In fact, the carbon emission in the film production process can not be ignored. According to a report of the British Film Association in 2020, each blockbuster in the world can produce 2840 tons of carbon dioxide during filming, which is equivalent to the amount of carbon dioxide absorbed by 3709 acres of forest in a year.

"It is of great significance for the film industry to participate in green and zero-carbon development." Zhang Chi, director of the Creative Guidance Department of the China Film Association and secretary-general of the Literature and Creative Committee of the China Film Association, said that while developing the scale of the film industry and improving the level of film industrialization, we should always be conscious and pursue low-carbon environmental protection. It is gratifying to see that domestic film and television bases and film production teams have made vivid practices of green and low carbon, such as Hengdian building a green studio and using photovoltaic technology to realize "shooting in the shed and generating electricity on the roof". Hainan Island International Film Festival builds a cooperation platform for environmental protection development, which plays a great role in promoting the green and low-carbon development of the film and television industry and improving the green technology level of employees.

The development of dynasties in the past dynasties has its ups and downs. China has a history of 5,000 years, and it has experienced too many special periods. The turmoil and painful experiences in modern history are particularly unforgettable.

During the Qing Dynasty, China entered a closed-door state.When the country was really opened, it became a piece of fat meat to be carved up in the eyes of western countries.

All kinds of reparations, aggression and expansion to western countries, as well as the evil deeds committed in our country, have caused us to lose a large area of land. In recent years, Tibet is famous for its many natural beauty.But what you don’t know is that there are still heroic deeds here.

In 1904, the British invaded Tibet again, and the weapons and equipment of the Tibetan army were very different from them. Although they tried their best to confront them, they eventually failed. This is the famous Battle of Gyangze.

In order not to be persecuted by the British army, the last 500 Tibetans who survived chose to jump into the river and die together. What happened at that time?

Throughout the history of western countries, you will find that what they like most is aggression and the development of more colonies. In their view, it is the main way to make themselves strong, and they have committed many unforgivable evils in the process.

If you look into it carefully,British troops invaded Tibet twice. After Queen Victoria came to power, she put forward a plan to defend India’s security.At that time, India had become a British colony.

Tibet is an important strategic area in the area she divided, trying to turn it into a British colony.At that time, the Qing government was faced with domestic troubles and foreign invasion, and signed the Yantai Treaty with Britain to reduce the pressure.

In 1880, the British army assembled troops on the Tibetan-Indian border and launched an attack on Longtu Mountain. Because of the poor equipment of the Tibetan army, it finally fell, so Tibet lost a large area of land.

The second invasion was in 1904. In 1903, the British major Rong Hepeng led his troops into the scallops in Tibet.We all know that the living environment in Tibet is relatively harsh, and the air is thin. British soldiers who came there for the first time have contracted pneumonia.

Under the influence of these multiple factors, the British army also became worried.So they thought of a plan, that is, pretending to talk.

The Tibetan army also chose to recognize the peace talks proposed by the British army. After all, no one likes war, but things have not developed in a good direction.The Tibetan army is very simple, but I didn’t expect it was actually a smoke bomb given by the British army.

When there was a false negotiation in front, the British troops in the rear gathered their forces and seized the top of the Tibetan army.After the battle, the British army concentrated all the bodies of the Tibetan army on the edge of the mountain spring. The blood flowing from hundreds of bodies melted the glacier and formed a blood river with the spring water.

A well-prepared banquet at the Hongmen Gate is undoubtedly an inhuman massacre.The British attack on the ground resulted in the death of more than 1,400 Tibetan troops, and only 380 survived.

Then the British army killed the defenseless Tibetans,In just a few minutes, the blood flowed into the river. After occupying Ji Gu, the large forces began to March to the Gyangze area again.

Along the way, the British army was defeated by six generals, and finally arrived at the gates of Gyangze. In order to preserve their strength, the people in the city and the Tibetan army chose to evacuate.

After entering the city,The British army started another massacre, plundered the grain and gunpowder in the city, and burned the buildings and temples in the city.After the British army swept through, almost no life in the city could survive.

The Tibetan army launched a counterattack while the British army was lax, but the strength of the two armies was very different. The number of Tibetan troops was many times higher than that of the British army, and the defeat was due to poor weapons and equipment.After several rounds of fighting, the British army finally forced the Tibetan army to the last stronghold of the government.

The Zongguan government has a relatively dangerous terrain, and it is in a high place, and it is protected by towering and solid walls. Why can it win the goal?The British army built several gun towers in a short time, and the castle was blown to pieces under the fierce artillery attack.

In addition, the British army cut off all the rear supplies of the Tibetan army, with no food, no water and no weapons support.The commander-in-chief of the Tibetan army knows that he will die if he drags on.

So one evening, he made a night attack plan with several subordinates, and a dozen Tibetan soldiers launched the final charge, but all of them died tragically in the end.

Seeing this scene, the Tibetan army can no longer tolerate it. Like the commander in chief,Several small forces launched a breakthrough in many directions, and finally only 500 people escaped from a path.

These people have also become the last targets of the British army. They are exhausted and injured to varying degrees.In order not to be captured and persecuted by the British army, all 500 people were killed in the river.

According to statistics after the war, Tibetan soldiers suffered heavy casualties, the number was probably in the thousands, and the British recorded that their death toll was only 37.The huge difference in numbers also reflects the bravery of the Tibetan army.

As a general who led the army to invade Tibet, Rong Hepeng’s evil deeds are countless.He once wrote in his diary that Tibetans were like lambs to be slaughtered, and Tibetan bodies were everywhere under the fire of the British army.

Tibetans defended Gyangze County for more than 100 days, and finally they were defeated by the fierce attack of the British army. The British army occupied Lhasa, and Rong Hepeng signed the Lhasa Treaty.

The victory of this war made Rong Hepeng honored. He returned to China with a lot of wealth, cultural relics and documents from temples.

The executioner was regarded as a hero in China and died of illness at the age of 79.It is reported that there was a golden Buddha hanging on his chest before his death, which he robbed when he invaded Tibet.

His purpose is to let the golden Buddha bless him to heaven.Because he also knows that he is evil and his hands are covered with the blood of the Tibetan people, his death has exposed his inner fear.

Repentance after death can’t make up for sins before death, and the Buddha will only cross over those who have great love.Rong Hepeng must have spent his later years in nightmares.Otherwise, how can a westerner who believes in God hold the golden Buddha for burial? Only the eastern gods can suppress the souls of Tibetans.

Although the Tibetan army was defeated in the battle of Gyangze, people have to admire their determination and perseverance,After the domestic situation was settled, the relevant departments set up a hero monument in front of Zongshan Mountain in Gyangze.

We have experienced too many similar battles in modern history, and the courage of the Tibetan people to defend their homeland to the death is really admirable.Their perseverance and spirit have made countless future generations proud and paid tribute to the heroes.

condom

Is the most common and popular at present.

A contraceptive method with high contraceptive rate.

But any kind of contraception

Are difficult to achieve.100% contraceptive rate

Condoms are no exception.

Today we are going to talk about

It’s just a girl’s sex life

What I am most afraid of-

Condom breakage

first

Don’t think

this is aMinimal probability event

In 2015

Researchers in related fields

A survey was conducted.

On the cause of unintended pregnancy

"The condom is damaged or falls off"

Accounted for 28%

And "no contraceptive measures"

Accounted for only 15%

Although this survey is one-sided.

But this data

It can explain to some extent.

"condom breakage" is not a small probability event.

Try to avoid it in daily use.

In order to better ensure safety.

Condom breakage

What are the causes?

The condom was accidentally damaged.

There are two main possible factors

First kind

The quality of the condom itself is not good

Condoms produced by regular manufacturers

It will pass before leaving the factory.

Electrode test, air explosion test

Pinhole water leakage test, dermatological testetc

The purpose is to ensure the quality up to standard.

Avoid breakage during use.

And some inferior condoms

The production process is not up to standard.

Pre-factory inspection

It is even more likely to be omitted directly.

This leads to the fact that during use

It is very likely that "breakage" will occur.

Want to avoid this situation

The way is actually very simple.

Through formal channels

Buy regular brand condoms.

Condoms are such things.

After all, the use site is special.

Those "three no condoms"

Presumably, everyone dare not use it easily.

So this point will not be discussed.

the second type

The wrong way to use it

Why did you use a regular brand condom?

It’s broken, too

That must be in the way of use.

There was an error.

Specific mistakes

Can be divided into three categories.

I bought it wrong.

first

Condoms are also dividedLarge, medium and small.of

Judging from the general data of men in the whole country

Usually, medium and large sizes will be more "fit"

But …

When many gentlemen buy condoms,

Don’t care about size at all

What number to buy is completely random.

There are also some gentlemen.

In order to "experience better"

Deliberately buy a condom that doesn’t fit.

The condom is too big, too small, too loose and too tight.

May lead to the use of.

Accidental breakage occurs.

Wear it wrong.

Some gentlemen wear it.

In order to achieve a safer contraceptive effect

Will choose "Wear two layers"

Two-layer condom not only can not improve safety

Instead, due to mutual friction.

Increased in the process of intense exercise

Damage probability

besides

There are also some wrong ways to wear them

Like putting it firstThe condom is fully deployed.

Then wear it.

Another exampleWear it too hard.

There is no space left at the top.

…

All these may cause

The condom is damaged during use.

Wrong use.

It’s not over yet

When it comes to formal use

There are still many pits you may step on.

For example, some gentlemen are more excited.

The action may be involuntary

Become rude

Although the surface of the condom

There is a protective lubricant.

butToo violent a movement.

It is still possible to cause damage.

There are people who are pursuing

Different stimuli

Select someHave sex in a special place

Like the bathroom.

High temperature, hot water, bath products

It is possible to destroy the structural stability of the sleeve.

Plus the environment like the bathroom.

Will make private parts dry.

This will greatly increase the risk of condom breakage.

in short

In order to "avoid winning the prize"

The mistakes mentioned above

Gentlemen must pay attention.

Don’t step on the pit.

Doctor, for a minute, the posture keeps rising.

-End of this period-

Because of the impact of epidemic and economic transformation, the population of third- and fourth -tier cities is flowing. Many of these migrant workers who returned from Shanghai, Shenzhen and other places are highly educated groups. In the golden area of ??third- and fourth -tier cities, they purchased houses in the "rich area", not only high -quality school district houses, but also supporting and greening are comparable to high -end houses in large cities. The houses in these high -end communities have risen first. Compared with other communities, the "hot island" effect appears, which is a lot higher than the surrounding house prices.

First, return home to snap up high -end houses

Many people who return home sell houses in big cities and buy a high -end house in their hometown. They can take their parents to live together. If you go back to the outside, you will have a place to settle in your hometown. Someone was affected by the mortgage of large cities. A loan of millions of dollars in a house made their lives and work suffer a lot of pressure. Buy a house in his hometown, and there are still funds in your hand to start a business or use it for daily life.

Second, the family replacement school house of the provident fund loan

Most families with provident fund loans are groups with stable income. Now many cities have increased the amount of provident fund loans and reduced down payment. They can buy a high -end house with a small amount of down payment. People who lived in the old town or high -rise houses were currently replacing high -quality school district houses. Therefore, high -end communities in third- and fourth -tier cities have recovered and rose against the trend, forming a sharp contrast with the surrounding second -hand housing.

Third, the scarcity of resources and the superiority of the location

Most of the "rich people areas" in third- and fourth -tier cities are mature communities built by large -scale housing companies that have been stationed before. From design style to supporting facilities are first -class. Now, many large real estate companies are far from the third and fourth -tier property market. It is difficult for local small development companies to have such a large handwriting, so it is particularly popular. The "rich area" is not only high in house prices, but also the local group is also rich or expensive in the local area. Therefore, house prices do not worry about selling the road.

From the trend of the property market this year, it can be seen that the rise and fall of the same city is blurred. So many favorable introduction, most of the property market is still not shocked. There are three changes:

01, the population continues to flow, but the house price is very strong

The phenomenon of the population of third- and fourth -tier cities is very common, and most of them are going out to make a living. If you say that Anjia Real Estate, you will choose to return to his hometown to buy a building. After all, house prices in large cities are high, living costs and housing costs are also high, and they can’t afford it. Therefore, many people will come to buy a neighborhood with good money outside. After all, Ye Luo will be rooted in the future, and now he will be filial to pick up his parents to life in the city.

02, interest rates have been reduced sharply, but most people do not buy a house anymore

Recently, with the introduction of the measures and interest rates, although the property market has stabilized and selling the building without panic, the transaction is still unconventional. Many third- and fourth -tier cities have no imagination scenes, and buyers are silent. Many families already have plans to buy a house, and the down payment can be available, but they are still watching and waiting. High -end communities are relatively hot, many people can’t afford it, housing prices in other areas are also falling, and few people buy it.

03, the vacancy rate increases, but the speculators do not throw the house

At present, the vacancy rate of third- and fourth -tier cities has increased by up to 30%. Many families have unstable income because of the high cost of housing. Therefore, when they return to the countryside, the house cannot be sold. There are also couples who work in the field. The speculators and groups of real estate have good housing in their hands, do not rent nor sold, and have no throwing house. Perhaps there are fantasies about the future property market.
