Fortune-tellers say that evil people do not take up, strange people do not take up, and good people do not take up. What does this sentence mean?

There are three things I don't take in the Book of Changes, very different people, very evil people and very kind people. The Book of Changes comes from life, so learning is easy to live. It means that the Book of Changes comes from life and reflects the universal law of life. Therefore, for the great difference, great evil, great goodness and other things beyond normal people, the Book of Changes will not be discussed, and fortune tellers will not give divination.
