Is it really bad to use magic door to calculate divination?

It is an apocalypse to make a living by fortune telling and help others solve disasters. Of course not. I can learn some principles and methods of doing things. Many fortune tellers often say that they have no noble personality, just a small personality, and can only be reduced to telling others' fortune. From what he said, I felt right. No saint will set up a stall to tell fortune. His realm is only for his own use, or to help wise kings unify the world and promote Yi-ology. In today's society, I suggest finding a way of life for myself, which can be used in business, politics and the like.
