There are many people studying Chinese medicine recently, and everyone has a common request: How to start learning? And hope to learn better in a shorter period of time. Therefore, it is natural to have a reference book that contains the basic theories and basic knowledge of traditional Chinese medicine so that you can get started and gradually improve. TCM treatment is mainly based on a set of medical methods that combine principles, methods, prescriptions and medicines. I personally think that the correct way to learn Chinese medicine is to understand the face of Chinese medicine from these four aspects, so as to understand the characteristics of Chinese medicine and master the rules of Chinese medicine treatment. Therefore, the narrative of this book is divided into four parts: theory, rules, prescriptions, and medicines. Within the four parts, several items are divided into more detailed introductions.
