Should the fortune teller believe what he says? Is it true?/You don't say. /You don't say. Is there any basis?

First of all, I can tell you for sure that Yi-ology can indeed be used for divination. Nowadays, there are many people who deceive people under the banner of Zhouyi, but there are also many Yi-ology experts. It is not easy to learn, so there are few experts. Listen to the fortune teller in the street, don't take it to heart. It can be said that it is not impossible to expose the truth and the level of fortune tellers. First, let him count what happened before or what happened to others. Second, according to the tone, if he speaks slowly and can tell the exact time, it proves that the level is ok. Third, beware of tone temptation, some people are deceptive "pseudo-easy to learn", similar to the current pseudo-science, because you do not know how to learn easily, so it is easy to be deceived. Fourth, don't believe the words of fortune tellers if they are exaggerated, because fortune telling is not omnipotent and has limitations, and its principle can only speculate on similar things. If you win 5 million, don't believe it, because fortune-telling can't be so accurate, which is an exaggeration. I can tell you that fortune-telling has a long history and originated from Yi-ology. Foreign scholars want to register for Yi Studies in their name. Therefore, as China people, we should protect the excellent culture of China. I can tell you that these are all based on the observation and summary of natural laws. This is just that we don't learn in general education, but there are still many experts and scholars in China who are committed to the study of Yi-ology. Otherwise, the Yi-ology will not be spread to this day, and I dare not say that the Yi-ology will always be the truth, but because the truth is influenced by the times and scientific progress, I think of Heliocentrism of Copernicus.
