Just like the question you asked, why are many things meaningless? Most people still have to believe it, especially some micro-signals are fake. Why do you believe it?
In fact, I think why people believe it, because I feel that this society has a strong power to spread information. We must have read one of your articles in the circle of friends. As long as everyone has read it, it may be forwarded. So there are more people who will spread some junk information in our circle of friends, so there are more people who believe it. Although I don't think it's credible, my relatives and friends forwarded it. Everyone thinks this information seems to be true, so I think many times it is blindly believed because many people forward it to everyone, so I think we should have the ability to distinguish this information. If it is too fake, don't believe it.
The second possibility is that some official WeChat accounts have some information about money, such as some investment and wealth management information. The article was well written and was forwarded by us. Moreover, to be honest, everyone wants to make money now, because life pressure is very great, so they forward a lot of information about investment and financial management. Some articles don't matter at all, but our people just go back and forward them. Some health information has not been scientifically verified at all, so we also forward it, so sometimes we have to try to see what this information is like before forwarding it.
