Japanese traditional Chinese medicine highly praised Zhang Zhongjing's Treatise on Febrile Diseases in the Eastern Han Dynasty. Three schools in ancient China only recognized Zhang Zhongjing's Treatise on Febrile Diseases. After that, Chinese medicine books abandoned the theory of Yin and Yang and paid attention to practice to produce truth. After the Song and Yuan Dynasties, the eclectic school of medical books believed that medicine should be absorbed by whoever is good. In a word, the Japanese's achievement lies in the return to rationality after China's traditional medicine entered Yin and Yang, which has made great contributions to the revival of modern Chinese medicine in China. For example, many modern Chinese medicine masters were greatly inspired after reading Hanshu and Emperor Medicine.
In addition, Japan attaches importance to abdominal diagnosis, which is the tradition of diagnosis and treatment in ancient China. In addition, Japan does not attach importance to pulse diagnosis because it is difficult for people who can really master and accurately use pulse diagnosis to see a doctor. This is also related to all simplification in Japan. There is also acupuncture in Japan. Cheng Danan, a famous acupuncture master in China, has learned a lot of real Chinese medicine by reading many books of Japanese acupuncture masters.
Traditional Chinese medicine has been criticized as a pseudo-scientific thing.
