What do you mean, "To learn Yi, learn witchcraft first"? I'm a beginner in the Book of Changes … What does "witch" mean?

Fallacy! ! ! There was already a witch when it didn't appear, and I don't know what inevitable role the witch played in it. Throughout the ages, many people have learned first-class and excellent things without learning witchcraft. If you know the Book of Changes and learn some witchcraft, that's fine. I have studied 10 years, and I have never heard of anyone who studied witchcraft first. What is a witch? It is a means to eliminate disasters and treat diseases for people. To put it bluntly, it is a branch of medicine, not the only way to learn the Book of Changes. I suggest you look at the mystery of Ceng Shiqiang's Book of Changes.
