CCTV News:Wang Tao has a beautiful resume: prestigious school education background, overseas study experience and numerous national awards. But Wang Tao thinks that the most precious thing is the evaluation of his predecessors in the circle: he is a young man who solves problems.

The problem that Wang Tao has to solve is related to everyone’s "personal life". As a researcher at the Institute of Engineering Mechanics, China Earthquake Administration, earthquake prevention and disaster reduction is his lifelong pursuit, and building sturdiness is his lifelong goal.

There is a saying in earthquake disaster science that "it is not the earthquake that kills people, but the building".

Wang Tao has been to many post-earthquake sites, participated in the rescue of Lushan earthquake in Sichuan, Yushu earthquake in Qinghai, Gongliu earthquake in Xinjiang, Nepal earthquake and other earthquake sites, and also did a lot of scientific research work on earthquake damage investigation of building structures in extremely difficult environment.

He deeply understands that only a strong house can protect life.

In the Wenchuan earthquake in 2008, Wang Tao found that the collapse of high-rise buildings was rare, but there were many cases of building abandonment caused by the destruction, and the coupling beam was the most seriously damaged component. In order to improve the seismic performance of high-rise buildings, Wang Tao led the team to conduct systematic research on new energy dissipation coupling beams.

This year, he just returned from Japan. Prior to this, Wang Tao had worked in the Institute of Disaster Prevention of Kyoto University for two years after receiving his Ph.D. from Kyoto University. When he learned that he chose to return to China to work in the Institute of Engineering Mechanics of China Earthquake Administration, the old-timers in the institute were particularly excited. Because in their eyes, Wang Tao is a "young and promising" and "daring and daring" scientist.

Facts have proved that the expectations of our predecessors have not failed. From material to structure, from connection to structure, Wang Tao’s team not only developed a new type of energy dissipation coupling beam system, but also directly served social engineering and achieved great economic and social benefits. It has been applied in millions of square meters of buildings and constitutes an important part of the national earthquake safety community.

It is an obvious feature of Wang Tao to "work harder" than others in scientific research.

Wang Tao graduated from the Department of Civil Engineering of Tsinghua University, but the seismic test involves many disciplines, which require knowledge of computer, signal processing, electronic circuit, control automation and other disciplines besides civil engineering. If Wang Tao is not good at it, he is knowledgeable and diligent.

Ten years ago, the earthquake engineering laboratory in the institute just started, and the equipment, instruments and personnel were very scarce. Wang Tao and the team members of the laboratory stayed up all night, from every screw to the connection test of various cables and data lines.

When doing experiments online with American scientific research institutions, Wang Tao led the team to start experiments at 8 o’clock every night according to the American schedule and worked until 5 or 6 o’clock the next morning. Watch the experimental results follow the expected trajectory, and sort out the experimental data at the first time. During that time, Wang Tao only slept for two or three hours every day.

Letting the research land is the ultimate goal of all Wang Tao’s efforts.

In the era of skyscrapers, earthquake resistance has become a new topic in the field of engineering construction, and Wang Tao has once again faced difficulties.

China Zun, one of the top ten contemporary buildings in China, is 528 meters high. It is the world’s first skyscraper over 500 meters built in an 8-degree earthquake-resistant area, and its seismic capacity has always been the focus of attention. Among them, Wang Tao’s team has successfully applied the research results of the project.

In the earthquake zone, the journey in 10 days is nearly 2000 kilometers, and the earthquake damage investigation is carried out in more than 40 towns and villages in Sichuan, which provides an important basis for the evaluation of earthquake intensity. In the city, put on a "coat" for brick-concrete structure houses to make Beijing’s old houses safe and livable for seismic reinforcement; In foreign countries, I assisted Nepal in scientific investigation after the earthquake, and often worked until two or three o’clock in the morning, still maintaining full fighting spirit.

In the earthquake, Wang Tao has been struggling to turn the building into a fortress.

It is estimated that many people have received similar sales calls, which makes people uncomfortable but helpless. So, how did the sales call evolve into a harassing call? Who the hell is calling us and in what way? How do they know our personal information? What should we do about these rampant harassing calls? CCTV’s "Focus Interview" reporter deeply harassed the telephone base camp and conducted an investigation.

Most mobile phone users will not be unfamiliar with sales calls, and many people will receive a dozen or even twenty sales calls a day. These sales calls are amazing. You can call outside, but you can’t call back. If you want to call back, the telemarketers will leave another mobile phone number. Can only pick up but can’t return, how is this done?

The reporter inquired about "telemarketing" positions on some recruitment websites, and found that many recruitment units offered salaries that sounded quite good, such as double salary commission and double salary at the end of the year, to attract employment, while the fields with large demand for them were mainly concentrated in insurance, wealth management, real estate, education and training and other sales industries.

The reporter first came to a real estate sales company. The scale of this company is not large. There are a dozen workstations. Each telemarketer has a computer in front of him. They wear headphones and keep talking, but they don’t see them dialing by landline or mobile phone.

Some staff told reporters that they dial through the computer system instead of manually dialing, so one person can make hundreds of calls a day.

The daily indicator requires calling for 7 hours and talking for 3 hours.

Another company that sells telephone insurance has a much larger scale. In the five-story office area, four floors are all such telephone sales stations. Some staff told reporters that there are more than 600 people selling by phone, not counting managers. Their goal this year is to achieve 1,000 people.

The reporter saw that the telemarketers on the phone spoke very quickly, some with manuscripts in their hands, some with words on the computer, and their mouths were endless. According to reports, they have their own set of special speech skills, and there are daily call length indicators, including the dial-up requirements, 3 hours in the morning and 4 hours in the afternoon, a total of 7 hours, and they are required to talk to others for no less than 3 hours every day.

It is understood that it is the requirement of many telemarketing companies to stipulate the basic number and duration of calls every day. In order to complete the daily call task, the telemarketers have to keep answering and trying to keep the other party on the line.

Similarly, this insurance company doesn’t need to make calls manually, and 500 or 600 telemarketers are automatically operated and assigned by the computer system. A telemarketing employee surnamed Liu told the reporter that the computer dials automatically. After dialing, the system will automatically find the operator, and the operator will automatically answer and cannot control it by himself. At about the same time, it is no problem to dial more than 50 numbers. Of course, most people will hang up the phone when they hear that it is telemarketing. In Xiao Liu’s view, success is still very difficult.

Automatic group calling without upper limit, low cost, and making money by issuing orders.

The success rate of telemarketing is not very high, so why are there still many companies that use telemarketing? Xiao Liu told reporters that telemarketing only needs to pick up a special telephone line, which is basically an uncapped package and can be played casually every month. The telemarketers all take the model of basic salary plus performance and commission, but in fact its labor cost is very low.

The reporter visited a number of telemarketing companies in succession to investigate, and automatic group calling by computer system is a common means for these telemarketing companies, which is easy to dial and low in cost, and once the bill is issued, it can make money. And a large number of sales calls come uninvited, which makes the majority of mobile phone users really annoyed and uncomfortable.

Customer data source: free insurance, APP personal data.

So, who is the sales call to? Where do customer resources come from? In this regard, these sales companies also have their own methods.

The reporter saw that in the computer system of telemarketers, the information of mobile phone users is clear at a glance. The customer information that is usually dialed will be saved by the telemarketers to their own customer resource library, and then they need to be dialed repeatedly.

In addition, because dialing through the computer, the displayed number often changes, which is difficult for telephone users to distinguish. In addition to chasing old customers repeatedly, the customer resources of telemarketing companies will continue to be updated. A staff member told the reporter that for telemarketing, data is life, not food, because there is data to achieve performance. In addition to some of its own databases, the rest of the customer resources are general quality data, and the data source is bought.

It is understood that there are two main sources of customers for telemarketing companies: one is the free insurance channel, and the other is the personal data left by some online APP platforms.

Intermediary service agencies cast nets all over the sky to call for customers, which is a marketing model that walks in a gray area. A company called you once or twice, and it didn’t steal or cheat. It doesn’t seem to be a big deal. However, many sales organizations in the society do this, which is extremely annoying and disturbing to users. This kind of unsolicited harassing phone calls has become a public hazard, which is not so much providing services as annoying anti-services. In an honest society, merchants should win customers by quality, service and reputation, instead of forced sales. As for those acts of collecting, trading and revealing citizens’ personal information for the so-called precision marketing, they have already violated the law.
