Introduce two books that I think are more important:
The Book of Changes is the basis of divination. When divination is broken, it is often relied on. If it is taught by a master, it is generally required to recite this book. Only by memorizing and understanding thoroughly can we have a better understanding of hexagrams and not break the wrong hexagrams.
This is a classic divination book. The content is easy to understand, and some contents need to be memorized before they can be understood.
I have tried to teach myself this knowledge, and I feel that it is more difficult to learn without a master. If you want to learn well, on the one hand, you should work hard and remember hard, which is the foundation; In addition, understanding is also very important. To understand the text thoroughly, you'd better find a master to teach it, hehe.
