To be a doctor, you should constantly learn to charge and constantly take exams to evaluate your professional titles. Very tired.

There are many subjects to learn. Take the clinical medicine of western medicine as an example. The most basic subjects are internal medicine, surgery, pediatrics and gynecology. These four subjects are the most important. Others include: pathology, physiology, pharmacology, psychology, microbiology, infectious diseases, traditional Chinese medicine ... I have graduated for several years, but I don't remember exactly. There are many anyway.
