Nowadays, many parents encourage their children to have plastic surgery. With the needs of social opening and competition, the phenomenon of plastic surgery for classmates has changed qualitatively. Both the students' idea of seeking beauty and the statistical analysis of clinical data in the past two years show that the social background of cosmetic surgery for students has changed obviously, and cosmetic surgery for students has become more and more rational, especially the support, recognition and participation rate of parents for children's cosmetic surgery is surprisingly high. Parents support their children to change their image and become more beautiful, which is a sign of social progress and civilization and conforms to the development of social trends. But be rational, vary from person to person, and don't fall into the misunderstanding of excessively "developing" external beauty.
