Is what Zhouyi said true or false?

The book Zhouyi is true, which has been proved by archaeology. The same is true of the theory of this book. Confucius and scholars of all ages have studied and contributed. Most modern people don't understand it for three reasons: first, thorough materialism does not allow idealism to exist; Second, its written rhetoric is simple and abstruse, which many people can't understand, which is not conducive to communication; Third, at present, its profound theory is only used for prediction, and sometimes it is used by superstitious people to cheat money and color. If you don't have the knowledge and perseverance of ancient Chinese, you'd better not learn it, not very much. But it's interesting to learn.
