The doctor who recommended me for an injection before, Dr. Xue Zhiqiang from Peking Union Medical College. Go and see him face to face and evaluate you, and see what a failure you are. He is super patient. If you don't do it from him in the end, he will give you a lot of pertinent advice. Xue Bo worked in Sino-Japanese friendship plastic surgery for more than ten years before starting his own business, and his rhinoplasty technique is very good.
