You will often meet some classmates in the Ninth Hospital to help you make good luck. If you are good, you won't do well. I suggest you go to the Ninth Hospital to see Professor Li Qingfeng, but if you want to see him, you must make an appointment. He is very busy, and there are Korean doctors in Shanghai, but not everyone is good. Some people think they are very capable. In fact, they are a mess, of course.
