I think the first thing is to choose the right hospital, and don't go to some informal hospitals and clinics to take advantage of it. Then it is necessary to follow the doctor's advice and do a good job of postoperative care. Anyway, I got it right. There's nothing wrong with it. By the way, I made it in Meilai, Hangzhou. If you are in Hangzhou, you can get to know it. This is quite good.
