How to calculate the fortune-telling of the blind?

Why are most fortune tellers blind? I asked myself this question many times when I was a child, and then I bought some books to get some understanding of it. Most people are really blind, and some don't pretend to be blind. For example, if you go to a fortune teller and you see that you are blind, he can't see you. He can ask anything with a string of words, and most of them speak the language of sitting on the wall. You don't have a dike in your heart because you want to get the result you want. This is an amateur fortune teller. Professionals, even blind people, will make field trips before fortune telling. If you want to tell your fortune, you usually encounter something very unsatisfactory, or you are unpredictable about your future and want to ask for help. If both sides think in one place, they can get the result. Those who don't pretend to be blind must be scum. There are two sisters working and they can't find a job. They are very depressed. At the alley, they met an old fortune teller who was blind. To count, the blind man asked if he could have a drink of water first, so the sisters took it home and gave him water to drink. Sisters don't need dams. They used to take off their coats because of the hot weather. After a while, the blind man couldn't hide it, saying, I can figure out where there is a mole on your body, so be careful, sisters.

Fortune-telling is difficult to be accurate. Even if you say something ambiguous, you can only fool those who have no knowledge and education and have to pretend to be blind. If you argue with your eyes and say the same thing, you will leave a stigma: arguing with your eyes and telling lies.

Predicting the trend of the stock market, just like the fortune-telling of the blind, is also difficult to predict accurately. But most people who predict the trend of the stock market are not blind, they are all fighting for their eyes, but they will still say it if they hit a wall. So, when the stock market rises, they lean on the rising side, saying that a day ago I said the market might rise here, but you just wouldn't listen, and so on.

This article unlocks the password: whether the stock market continues to rise or fall, technology is useless, don't look at technology, don't listen to predictions, and don't ask fortune tellers; The stock market is relatively balanced and technology is useful. It depends on the technology, but don't listen to predictions and ask fortune tellers. If you study independently, what you get is useful.
