If you don't understand, look at the basic theory of Chinese medicine first, then at Chinese medicine, and then at recipe science. This is the current teaching mode, and at the same time, it softens the four classics, namely, Neijing, Typhoid, Synopsis of the Golden Chamber and Treatise on Febrile Diseases (see below for details).
The ancient educational model is as follows: Huangdi Neijing (Su Wen and Ling Shu), Treatise on Febrile Diseases and Miscellaneous Diseases (Treatise on Febrile Diseases and Synopsis of the Golden Chamber), and Study on Febrile Diseases.
Learning Chinese medicine requires perseverance and understanding.
