Did nan huaijin say not to learn the Book of Changes?

Nan huaijin said that he was afraid to read the Book of Changes at night, because he would never stop reading it at night. The problem of the Book of Changes is interlocking, and it will change from one divination to another. So Mr. Nan will find another question after reading one question, and then he wants to see the answer to another question. After reading another question, there is a third question, which goes on endlessly and unconsciously.

This is the Book of Changes. There is an ancient poem "I don't know how long spring has passed". I was so fascinated by the Book of Changes that I didn't even notice that spring had passed for a long time.

Teacher Nan didn't really tell you not to learn the Book of Changes, but told you that the Book of Changes is very addictive.
