Why is it that a person around you is self-taught in Chinese medicine. Just learn it like reading a novel. Once you learn it, you know it. What does it mean? What kind of person is this?

It means that this person has an active mind. Chinese medicine is not like Western medicine, Western medicine has a solid theory, rote memorization can be learned. Chinese medicine requires association and divergent thinking. The same disease, Western medicine only a what what disease results, but Chinese medicine is divided into congenital, acquired, or caused by dampness, caused by heat and so on. All these require divergent thinking and carefulness. But Chinese medicine is easy to learn and hard to master, and needs experience to pile up.
