To answer this question, you must first understand the principle of freehand plastic surgery. In fact, freehand plastic surgery comes from Japan, which can be called Japanese osteopathy technology. Its principle is to adjust the gap between bones and finally achieve a plastic effect. The main reason is that with the growth of age, the long-term dislocation of bones caused by some wrong living habits or postures can generally last for three to five years, and it can last for life like a nose. I learned it after studying Japanese osteopathy in Songhe, Suzhou.
