There are many directions in TCM internal medicine. What direction to choose depends mainly on your own planning for the future. Because every major has advantages and disadvantages, the gynecology you mentioned is actually quite good, and the curative effect of gynecology in traditional Chinese medicine is also positive. As for beauty and health, it seems that there is no school to offer a doctoral degree in this major. Beauty and health is a miscellaneous subject, which needs to be studied in surgery at universities and colleges. You can learn basic internal medicine, surgery and gynecology well. Only by keeping in good health can there be a foundation. Of course, I want to remind you that studying for a doctorate does not necessarily mean doing clinical work. Most of them are mainly scientific research, and they may spend three years in the laboratory. Hehe, don't expect too much from the doctor, and it may not be as you wish in the end.
