If LZ's Chinese character face is a bone problem, you must use a knife to change it into a melon face, but if it is caused by a large masseter, you can use a face-lifting needle. This means that you don't need to use a knife. It only takes about 10 minutes to soften the masseter muscle and turn it into a melon face. I recommend Shanghai No.9 Hospital, Beijing Yezi, Plastic Surgery Center of Kunming Medical College and Chongqing Contemporary Plastic Surgery, all of which are powerful hospitals. As for doctors, Professor Zheng Yanqing and Professor Jiao Guangyin are the authorities in this field. They have nearly 30 years of experience and a very good reputation.
