It is suggested that the landlord should start with the basis of traditional Chinese medicine, but don't study too much, just swallow it. Then find a special visceral physiology. Zang-fu organs are the core of the foundation of traditional Chinese medicine, which can also make people understand the connotation law of traditional Chinese medicine. There is also a very thick interpretation of Treatise on Febrile Diseases written by Liu Duzhou before his death, which is not only close to clinic, but also embodies the foundation of traditional Chinese medicine. This looks interesting, too. As for the Emperor's Canon of Medicine, hehe, I suggest that we wait until we achieve something.
In fact, many things in TCM are ambiguous. But this is also the charm of Chinese medicine. There is no very definite answer, it depends on your own understanding of Chinese medicine.
