Home, will it heal the pain, or tear the wound, so that the pain has nowhere to hide? In the movie "Secret Visitor", the well-off Wang family was supposed to be a "perfect" model family, but with the intrusion of the school bus driver (Duan Yihong, played) who caused a major school bus accident due to negligence, the family began to have the secret of unscrupulous growth.

Home is an eternal exploration　

Director Chen Zhengdao uses "Secret Visitor" to poke the audience’s pain points towards "home"

From "Skyscraper" to "Skyscraper", the combination of suspense and topical social insights has always been the "specialty" of Chen Zhengdao’s director, and "Secret Visitor" is no exception. This time, he hopes to explore the meaning of "home" with the audience. Through the school bus driver who refuses to confess to the accident due to dereliction of duty, and the four Wang family members who seem to have become strange because they protect their families and seem to be "illegal" to protect secrets, the vivid characters establish dramatic conflicts, and put social reality topics such as "home is a harbor or a cage" and "school bullying" into suspenseful reasoning, so that the audience feels "grounded" and more likely to resonate.

Director Chen Zhengdao admitted that family has different meanings for everyone, and it often fetters people’s lives. This time, "Secret Visitor" puts all the themes in a "home", and everyone has to play their own role in the home, and hide their own secrets. Even pay the price of home for home, which is thought-provoking.

No matter what kind of social product it is, its ultimate goal is to help users build links. Since the development of social products, the form has matured. Among them, relationship chain, interaction and content are the core elements of social products. This paper analyzes these three key elements, hoping to bring you some inspiration.

After working in an outsourcing company for more than two years, I joined a startup company and started my own exploration in the social field as the head of its overseas social application. In the following time, I will summarize my exploration experience in writing regularly and share it with you.

I’m not very knowledgeable. I hope everyone can learn something from it.

If we want to make a good social product, there is no doubt that the first thing we need to know is: What is social?

According to the definition of Baidu Encyclopedia, socialization (that is, social communication) refers to the social activities in which individuals communicate with each other for material and spiritual exchanges under certain historical conditions.Because the essence of animal society is the sum of all social relations formed on the basis of material production and labor, social communication is the inherent requirement of animal nature to a certain extent.

In the past, people’s social activities included offline salons, blind dates and even chatting among friends, and the Internet brought new social ways, and social products such as WeChat, Soup and soul emerged one after another. People have met their needs for material, information and spiritual communication in various ways.

However, just as a successful person owns a house and a car, we cannot define that success equals a house and a car.Whether it is the exchange of materials or the exchange of information and spirit, it is only the appearance of social interaction to a certain extent. I think the essence of social interaction is linking.. Based on the link, one person, a group of people, established contact with each other, thus having the possibility of exchange.

At the same time,The formation of links is limited and influenced by time and space. Based on different link subjects, media and forms, various types of social products that we are familiar with have emerged.

For example, distinguished by the main body of the link, it links the social application WeChat of acquaintances of relatives and friends, and links the social product soul； of strangers who have no contact with strangers; Differentiated by link media, there are interest-based social applications and LBS social products based on geographical location. In terms of form, there are audio social products Hertz, video social products HOLLA, cat call and so on.

butNo matter what kind of social product it is, its ultimate goal is to help users build links.

Relationship chain is one of the core elements of social products, which refers to the connection between people. The network formed by the combination of multiple relationship chains is what people often call relationship network.What is human nature? Marx concluded that "the essence of human beings is not an abstract thing inherent in a single person, but in reality, it is the sum of all social relations". In our daily life, no one can get rid of "relationships". Relatives, friends, classmates and partners have various relationships, strong and weak.

Different types of social products often have different entry points for the relationship chain.

Cut in with a strong relationshipWechat, which everyone is very familiar with, is a social product based on strong acquaintances, not only WeChat, but also most IM products such as WeChat and QQ. The key to acquaintances’ socialization lies in whether they can successfully transfer the offline relationship chain of users to online, thus making the communication between acquaintances more convenient. Once the relationship chain is successfully migrated online,The strong relationship between acquaintances is itself a very powerful moat for acquaintances’ social products.In my opinion, this is why it is difficult for new acquaintance social products such as Duoshan to shake the dominance of WeChat in the social field of acquaintances.

At present, there are still new social products coming into the market, such as soda and other products that I brushed recently when I brushed Tik Tok. Most of them areCut in from the perspective of weak relationshipSocial networking products for strangers. At present, the more successful social products for strangers in the market include Momo based on LBS, soul with three views matching as the selling point, Hertz with the main voice socialization, Douban with interest dimension, Post Bar and so on.Weak relationship is the starting point of strong relationship. Compared with strong relationship, the establishment cost and migration cost of weak relationship are much lower.This is why it is difficult for a monopoly giant like WeChat to appear in the field of strangers’ social interaction, and why there are always new products coming into the track of strangers’ social interaction.

butDue to the low credibility of weak relationships, most social products of strangers have to improve their credibility through various channels to realize the core value of the products.For example, social products with heavy value such as Momo and exploration will require users to authenticate with real people, while soul, which focuses on soul socialization, provides users with psychological test questions.

The strength of all relationship chains may fluctuate with time. For the same relationship, such as partnership, the feelings of couples who stay together every day may continue to heat up, and couples who have been separated from each other for a long time may become unfamiliar. The fluctuation of relationship strength is inseparable from the interaction between them.

Interaction is also the core element of social products.

Interaction refers to the process of interdependent behavior between individuals, groups and groups in society through language or other means to spread information.It takes two hands to clap, and one person can’t interact.

Users who establish relationships can interact, and the interaction between users in turn affects the stability and strength of the relationship chain. The key is thatInteractive mode, intensity, frequency and value..

Taking the common Internet social products as an example, in most products,Common interactive behaviors include chatting, liking, commenting and forwarding.And different interaction modes correspond to different interaction intensities. For example, the interactive intensity of comments is greater than that of likes. And the same is chat, the interactive intensity of video chat is generally greater than that of text chat.Under normal circumstances, the greater the intensity of interactive behavior, the easier it is to enhance the closeness of the relationship between users.

For the same kind of interaction, the higher the interaction frequency, the closer the general relationship. But this is not absolute, because whether user interaction is effective or not, there is also a very important key point, that is, the value of interaction.

There are a thousand cups of wine for every bosom friend, and more than half a sentence for lovers. In our daily life, we may encounter such a situation. For example, at work, some colleagues have worked with you for a long time, and you are still familiar strangers after work for a long time, while some people have become friends through a few supper after work, even though they have not known each other for a long time.The reason for this difference lies in the difference of interactive value.The communication with old colleagues may stop at work. These exchanges are conducive to the smooth development of work, but they can’t make you know each other better. However, chatting in different places during the string talks makes you have a basic understanding of each other’s hobbies and values, thus becoming friends.

Interaction is the key to the generation and change of the relationship chain between users, but a good interaction can’t happen out of thin air.When posting a comment, there must always be someone to comment on and chat with others. The key is to talk about what won’t lead to embarrassing chat.The key auxiliary information is the content.

Content is auxiliary information to help users interact, which refers to the information that users disclose to others.In the early days of the Internet, limited by the network technology and network speed, the content display among users was mainly in words, resulting in pure text social products such as BBS, blogs and IM tools. With the maturity of the processing technology of pictures and audio and video, various types of content such as pictures, audio and video began to participate in social activities in a richer form.

For any social product, the content supply chain is basically composed of three main links: content production, content distribution and content consumption, and how to optimize the content supply chain is particularly important for all social products.

To guide users to output valuable content, we can refer to the concept of value proposition in economics and encourage users to output content with internal or external value, which can be in the form of spatial dynamics, photo wall and so on.For products with sliding pairs such as tinder or Explore, they encourage users to upload more personal photos and update more real personal information, which belongs to the content produced by users. Of course, how to recommend suitable users to each other is what tinder and explorers need to consider in the content distribution. For products such as Tik Tok, Yikan and Weibo, which focus more on content socialization, besides personal data, they will try their best to let users publish more dynamic content, such as providing them with tools for editing pictures and videos, lowering the threshold for dynamic publishing, and providing material or spiritual incentives for high-quality content, thus encouraging users to produce content. With sufficient content sources, content distribution has become a top priority. For example, Tik Tok is famous in the Internet circle for its extremely powerful content recommendation algorithm.

Of course, we can’t be anticlimactic. On the consumption side of content, how to help users consume content better and encourage users to interact with content producers based on content is the key ending to complete the whole social closed loop.

In subsequent articles, I will further discuss the content supply chain, so I won’t expand it here for the time being.

This is the end of the article, hoping to play a role in attracting jade.

△ Video: "Challenge Impossible"

CCTV News:Today is "119" Fire Day, and some people call fire fighters "retrograde heroes", because whenever there is a crisis, all people are retreating backwards, and only fire officers and soldiers are going retrograde. Touched by the spirit of courage to take responsibility and dedication for these lovely people, their superb skills are also impressive and admirable.

No, recently, an armed police fire fighter in Gansu province showed his exquisite skill of blindly cutting steel wires on light bulbs with a toothless saw in the inspirational program "Challenge Impossible".

Fire fighters blindly cut steel wire bulbs on the bulbs without any damage.

The soldier’s name is Li Haifeng, and his challenge is to blindly cut the steel wire fixed above the light bulb through a thick steel plate with a toothless saw.

△ Toothless saw

The distance between the steel wire and the bulb is only 0.01 mm.

After 45 seconds, the steel wire broke with a bang, and Li Haifeng quickly received the force, and the light bulb was not damaged at all.

In the end, Li Haifeng challenged successfully and won applause and exclamations at the scene. Of course, such skills are not limited to stage performances, but are more used in Li Haifeng’s rescue work.

For example, once, a 16-year-old boy couldn’t get the ring off his hand. After trying to cut the ring with tools such as steel bar breaker, pliers and saw, Li Haifeng decided to use a toothless saw.

He wrapped the boy’s hand with a towel in order to prevent the sparks from cutting from hurting his skin. During the cutting process, he kept watering the boy’s hands to cool down because of the fever.

In the end, Li Haifeng sawed off the ring with a toothless saw and successfully saved the boy’s finger.

After 17 years of practice, I have developed an extraordinary stunt.

When Li Haifeng challenged to cut the steel wire, he relied on hearing and touch. He said, "The right ear captures the sound of the engine, and the left ear distinguishes the friction of the grinding wheel." The summary of a short sentence embodies the sweat and hardships of 17 years.

In 1999, 19-year-old Li Haifeng joined the army from Hebei and became a fire fighter of Gansu Baiyin Fire Brigade. A few years before joining the army, Li Haifeng has been the squad leader of the rescue class, specializing in demolition technology. In 2010, he began to try to cut the steel wire on the light bulb with a toothless saw. From the initial watching to the later blindfolded cutting, Li Haifeng exchanged three years of tenacity and sweat for the unique skills in the country today.

"In three years, I chopped up more than 1,000 light bulbs." Li Haifeng said that from the initial lack of confidence and the discouragement of countless failures, he experienced painful hardships again and again. "Now, I have formed a deep feeling with the light bulb."

Facing the test of life and death, be a pioneer in emergency rescue again and again.

Since joining the army at the end of 1999, this military uniform has given Li Haifeng a strong sense of mission. At the age of 36, he rescued 188 people in distress, protected tens of millions of materials and property, and won many honors. He is currently the deputy director of the training department of Gansu Provincial Public Security Fire Brigade, and his injuries are as many as the awards he won.

Over-training and accidents in many rescue accidents, Li Haifeng suffered six fractures, numerous minor injuries, severe varicose veins in both legs, and unbearable pain at the fracture site every cloudy day. And he said: "There will be a lot of aerial work in fire fighting and rescue, and there will be many accidents in emergency rescue, which will inevitably lead to sprains and bruises, which is normal."

△ Li Haifeng blindly cut the steel wire fixed above the bulb through a thick steel plate with a toothless saw.

Now I have a skill, but I was afraid at the beginning. Li Haifeng recalled that in 2000, not long after he joined the army, he once performed a extinguishing task, and the squad leader asked Li Haifeng to set up the gas tank. "After the rescue of personnel was completed, in the face of the explosion of liquefied gas at any time, at the moment when all firefighters were ready to evacuate, the captain asked me to help the liquefied gas tank immediately. To be honest, I hesitated for a moment, because I was really scared. The liquefied gas tank was still breathing fire and could explode at any time. " Despite his inner fear, Li Haifeng did it at once. Just turning 20, he felt as if he had passed by death.

△ Li Haifeng participated in the second season of "Challenge Impossible".

I have participated in various rescues for more than 3,000 times in 17 years, but the more I have seen life and death, the deeper I feel awe. "I remember a multi-person car accident in Baiyin No.1 Road in 2013. When we rescued one of the ladies, she had no signs of life. At that time, her son kept crying, and her husband immediately knelt down and kept kowtowing to us and begged us to save her. At that time, I felt my heart was bleeding, and I really felt very ‘ Incompetence ’ . Life is particularly fragile, and all fame and fortune are not important in front of life. "

This job also gives Li Haifeng few opportunities to reunite with his family. Li Haifeng’s wife said in the program, "Although we get together less and leave more, the day we marry Li Haifeng, we are ready for all the psychological preparations we need to bear as a military spouse." A simple sentence made the host Dong Qing and many viewers shed tears on the spot.

Li Haifeng’s soul-shaking skill display is precisely because of his deep sense of responsibility and mission. He explained the word "hero" in peacetime with the most practical actions.
