The Book of Changes is not a fortune teller.

Accurately speaking, Zhouyi is a Confucian classic, which was later quoted by Taoism. A lot of things about hexagrams mentioned in it are actually based on science. Everything moves regularly, and the Book of Changes is based on this natural law, not the so-called "superstition". "Fate" is "calculated", that is, according to your own state, environment and many other factors, if you continue to develop in this state, what is the most likely result. It is not "made" without any evidence. Of course, many "fortune tellers" we see now have no reasonable explanation, or are not allowed at all, because they are just swindling under the guise of China's ancient culture. If we really study the classics like Zhouyi, we can find that many of them are explaining the laws of nature, not people's subjective thoughts. The laws summed up by these ancestors, because there is no explanation, are considered as "superstition" by many later generations. Although there are still many laws that can't be explained, I believe that scientific and reasonable explanations can be found. What can't be explained now, I think, is due to the serious division of modern disciplines, which leads to the close relationship between disciplines. Because the laws summed up by our ancestors are often not limited to one discipline, but involve astronomy, geography, chemistry, medicine and even psychology. Keep studying hard, and maybe one day you will be enlightened.
