My mandibular angle was very wide since I was a child, and I was laughed at for saying that my face was so wide and ugly. When I grew up, the love of beauty forced me to change my mind, so I had the determination to do bone grinding surgery. At first, I didn't know what was good. Later, I learned that Dr. Huang Dayong's bone grinding and face changing surgery is very famous. After reading his case, I came to Beijing to meet him face to face.
