What does it mean to say that fortune telling has a degree?

Please answer those who understand the Book of Changes! If the evil spirit takes the school and Wenchang nobles, will he study hard?

The Book of Changes is a trend forecast, which does not mean that it will definitely happen. It depends on a person's nature and personality characteristics, and the final result needs a process. There are too many variables in this, many of which depend on the efforts of the day after tomorrow. Moreover, the Book of Changes is a way of educating people to be human beings, which is different from fortune telling. Learning the Book of Changes well is not a good sign, but a good doctor!
