A person who teaches Chinese medicine by himself needs to buy some formal Chinese medicine books and do more research. He needs to ask questions about the principles he doesn't understand, and ask more people in old Chinese medicine or clinics, which will better consolidate his common sense. Moreover, self-taught people need patience and can't give up halfway, otherwise they will be irresponsible to patients.
Practice makes true knowledge, even if it is self-study, you should go to the field and learn from it. When you face real patients, you will naturally explain to them more patiently and let them trust you, so this sense of responsibility and sincerity is still necessary.
