The numbers are easy, and the eight characters are accurate?

There is no such word in the Book of Changes. I ching pays attention to the process, but it is only a process of seeking good fortune and avoiding evil. It won't give you an answer, it will only give you a possibility. If you do this, the result may be like this. If not, the result may be like that. So since you believe in the Book of Changes, you should know that everyone's life is in their own hands, and the numerology of a person's life is drawn by themselves.
