Does the Book of Changes teach divination?

Zhouyi has many branches. Now there are plum blossoms, and the numerology characters of Liuyi, Daliuren and Qimen are also called four pillars. The other is Tai B, which is not commonly used, and there are some small factions, such as Xiao Cheng Tu and Xiao Qi Men. .....................

Of course, there is feng shui, and there are many branches of wind and water. There are eight houses in all. The nine planets, Shen Kong (also known as Kong) and most of them have many branches, such as the twenty-four mountain tactics. ........................

However, if you want to learn Yi, you must know that mathematics and physics are not separate. If a branch loses these, it is basically useless.
