Students sincerely ask for advice, I hope you can give me advice. (About Zhouyi)

Dude, if you want to learn Zhouyi, I suggest you look at the things about Yin and Yang five lines of gossip in the basis of traditional Chinese medicine. The most important thing about Zhouyi is to talk about sixty-four hexagrams, which are composed of eight diagrams in pairs, and eight diagrams are composed of yin and yang, so you can't understand Zhouyi without understanding yin and yang and five elements.

China said in ancient times that Zhouyi and the basic principles of TCM are interlinked, which is true, because their basic principles are all Yin-Yang and Five Elements. However, the theory of Yin-Yang and Five Elements is not specifically talked about, but it is easy to explain, and there is only the basic part of TCM in universities. After reading these basic theories, you can look at Chen Menglei's Introduction to Zhouyi in Qing Dynasty and Zhouyi Biography at the peak of the Republic of China. I recommend you to read Chen Menglei's book, because his book is written for Qianlong, which is not difficult for beginners to understand.

In addition, there are many branches in Zhouyi. Now divination is divination and geomantic omen, and divination is divination. According to the theory and technology of divination, it is divided into many sects, including six hexagrams prediction and escape, among which six hexagrams is the simplest and most basic, and it is difficult to get started, but it is easy to learn as soon as you enter the door. Feng shui is to look at the wind, and there are many schools. The famous schools are Bazhai and Kong Xuan. There is no feng shui content in Zhouyi itself. The theoretical system of geomantic omen is summed up by later generations according to experience and the basic theory of Zhouyi, so it is necessary to read specialized geomantic omen books, but the content has little connection with Zhouyi, so it is easy to get started, but it is difficult to learn the essence.

Regarding the study of geomantic omen and divination, I personally think that if you want to learn both geomantic omen and divination well, you don't have to study this specially, so you don't need to spend too much energy. Just do your divination. But if you want to learn, in view of your good foundation in ancient Chinese, you can read some classic and introductory books, such as Guo Pu's "Buried Classics" and the anonymous "Ten Books of Yangzhai" in Qing Dynasty.
