Who can tell me what I need to know to learn the Book of Changes? Besides, what are the hexagrams of the palace? I need more details. I am very grateful.

There are many kinds of subordinates in the Book of Changes, such as Meihuajiu, Liu Yi, Daoism, Liu Ren and Wei Zi. Most beginners suggest learning five lines of gossip of Yin and Yang first. You need to remember 64 hexagrams. Then understand the prosperity of the five elements in each season. This is the foundation.

Next, you can take a look at Shao Kangjie's "The Easy Number of Plum Blossoms", which is a very simple introductory book and contains very detailed basic knowledge. I suggest you read more. The uterine divination you said is what is in the six hexagrams. Every hexagram has its own hexagram, one * * *, and there are eight hexagrams, and the root of Gankan is really separated from Kun for these eight hexagrams. There are eight hexagrams under every eight hexagrams, a total of sixty-four hexagrams. Six hexagrams are a little more difficult than plum blossoms. You can learn the introduction of plum blossoms first. In addition, I recommend a Book of Changes Miscellaneous Notes by Mr. nan huaijin, which has a good comprehensive explanation of the Book of Changes. You can take a look at it first to get a better understanding. I hope it helps you.
