I am a high school student, and I want to know how to learn Zhouyi Metaphysics and Feng Shui Yin Yang.

I wonder how good your ancient Chinese is. When studying Zhouyi, it is suggested to start with reading ancient books and directly read the original text and annotations of Zhouyi. Think more, not three minutes. In addition, we should also try to get rid of all kinds of desires and troubles and calm our mind. The so-called "quietness can communicate with God". Only when you are calm can your mind better receive the ideas to be expressed in the book. On the other hand, we should strive to improve our moral cultivation. As the saying goes, it is impossible for a villain to guide his life with the Book of Changes. If you study the Book of Changes as a philosophy, then I suggest you read other Confucian and Buddhist books. If you are studying Zhouyi for divination, I suggest you read books such as The Book of Changes of Plum Blossoms and Addendum. I also came into contact with Zhouyi in high school and became interested in Zhouyi. Of course, I'm in college now, so work hard. In addition, there are many Zhouyi forums on the Internet, you can also visit them, or, if it's fate, you can find someone you trust to study.
