I don't know. Tian's technology is hers. They didn't know which university they graduated from. It seems to be in an encyclopedia. It says 1986. They went to Guangzhou Southern Hospital to study plastic surgery, which showed amazing talent in eye and maxillofacial plastic surgery, and they had their own unique ideas and opinions on each plastic surgery, especially eye plastic surgery. With his persistent love and innovative spirit, on the basis of many years of clinical plastic surgery experience and exchanges and cooperation with authoritative experts at home and abroad, Director Tian has constantly learned from each other's strong points and brought forth new ideas, creating and researching unique stunts such as "Tian's seamless eyelid upturning" [1] and "Tian's small eyes wide open", which are most in line with oriental aesthetic standards. She is famous for her little trauma and amazing recovery speed, and she has indisputably become the chief eye plastic surgeon in Central China.
