What are the divination methods in the Book of Changes and the main points of the book?

I think everything above is a little dizzy. To put it simply: divination in the Book of Changes is these steps, such as divination-divination-divination-divination (divination period) and so on. But each step has many methods and steps. However, the Book of Changes does not contain 64 hexagrams, such as images, pictures, hexagrams, conjunctions and ci. Therefore, if you want to use the Book of Changes for divination, there are many systematic auxiliary books to complete divination. The most important thing is to master the basic knowledge first, such as heavenly stems and earthly branches, five elements interacting with each other, six gods, how to start divination, how to install divination, where to change divination, how to read divination, how to break divination, how to determine the timing and so on. I believe that if you know more about it, you will gain something. These are all my experiences and understandings, and I hope I can help you.
