In late March, a stranger added me to WeChat, and then invited me into a WeChat group (WeChat group name: Zhang Hui stock market fan group). I was invited to a stock exchange group in April. In it, several stocks recommended by the instructors are hit limit-up continuously. The live broadcast room I joined later was called "Hong Shan Capital.", in which there were four instructors, Teacher Zhang, Teacher Zhao, and Teacher Tang. They explained the stocks daily. The instructors also broadcasted live, early, middle and late every day, introducing stock trading techniques, analyzing the stocks we hold. They told us how to build positions and trade. These four instructors participated in a stock market competition in a group. Instructor Zhang Hui asked us to vote for him so that he could win the 5 million prizes. Moreover, when the market is about to close in the afternoon of the trading day, they are often recommended to us in the live broadcast room some end stocks to let us earn money to gain our trust. After that, the live broadcast game is coming to an end. They said, in order to thank us, they must bring us to make money together. So, the instructors said that the current stock market is not good, it is better to do stock index futures, on which you can trade in both directions, that is, you can also make money when you buy short. Then they disbanded the stock group on April 12 and set up a team led by Yang Wulong. I joined the Toyota team. The instructor said that we can turn our principal five times. But because the market has been falling, stocks are not good to trade. Because the stock does not make money, the instructor said that the market has been falling, it is not suitable to trade stocks, and is willing to make money with us in option index. The instructor used his account in the live room to demonstrate how to operate the china300 (CSI 300) index for trading. The teacher said that he deposited 6 million RMB, using MT4 software.
