2. Introduction: After you have interest, you should start to lay the foundation. Should be based on modern vernacular works, plus previous interests and some foundation, should be able to stick to it. Recommend the basic theory of TCM, Chinese pharmacy, TCM thinking, Hao Wanshan's lecture notes on febrile diseases, Hu Xishu's lecture notes on febrile diseases, synopsis of golden chamber, etc. This stage is mainly to lay the foundation, systematically study the basic theory of traditional Chinese medicine, the medicinal properties of commonly used traditional Chinese medicine and so on.
3. Improve: At this stage, we should gradually deepen our understanding. From this stage, it began to sublimate, and this stage is still dominated by ancient prose. What needs to be seen is: ancient Chinese medicine with circular motion. After studying, I will study Huang Yuanyu's works, such as The Source of Four Sages' Hearts, The Disparity of Four Sages, Su Wen's Suspended Interpretation, Difficult Classics, Treatise on Exogenous Febrile Diseases and so on. With the guidance of senior Huang, I can get twice the result with half the effort. It is not impossible to understand these classics by yourself, but this is the same strain of ancient Chinese medicine. So the height of the theory lies in how much it can be thoroughly understood at this stage. This stage is also the most important stage of learning Chinese medicine.
