Ear burns can be cosmetic. It is best to go to a local regular plastic surgery hospital to do ear plastic surgery for my brother. The sooner the better. Don't go to small places for plastic surgery. Needless to say, most doctors are fake. Not only did they fail to do it once, but they also asked your brother to open a second knife! If you are from Changchun, I suggest you go to the Plastic Surgery Department of the First Hospital of Jida University, which is the most famous big hospital in Changchun and even Jilin Province. It is absolutely safe to go there for plastic surgery!
