Is the Book of Changes credible?

Of course it is credible. The Book of Changes is the crystallization of the great wisdom of our ancestors, which is very scientific. As for why there is superstition, it is mainly because the Book of Changes is too abstruse to learn, so few people really understand it. In addition, for thousands of years, all charlatans who have a little knowledge of the Book of Changes have used it to cheat, and more people naturally think that the Book of Changes is not credible because they have not met a real master.
