During the Jin and Southern and Northern Dynasties, the development level of surgery and surgery in China was relatively high. Let's first look at the actual level of modern plastic surgery. Biography of Wei Yong in the Book of Jin: "Wei Yong was born with rabbit lips. At the age of eighteen, I heard that Jingzhou secretariat of Yin Zhong was comparable (? ~ 399) There is a famous doctor who can cure under the account, just to seek treatment ... "Wei Yongzhi came to Yin Zhongkan's house to explain his purpose, and the enthusiasm of Zhong Kan's family made him hire a doctor for the diagnosis of Yong. The doctor said: Cleft lip can be repaired by surgery, but you can only eat porridge for 100 days, and you are not allowed to laugh. Yong Zhi said after listening: Even if you don't talk for half your life, you still have half a life, not to mention that you can't laugh for only a hundred days, so you must be cured. So Zhong Kan arranged a living room for Yongzhi and asked the doctor to repair it wholeheartedly. Yongzhi listened to the doctor's orders, kept silent and only ate gruel. Cleft lip repair surgery has achieved good results. Wei Yongzhi went back with great satisfaction after the operation. Although this account failed to describe the specific methods and steps of the operation in detail, the operation did achieve satisfactory results, indicating that the congenital cleft lip deformity had been well repaired in the Jin Dynasty and reached an ideal level. Unfortunately, there are always people who suspect that China could not have reached such a high level of surgery at such an early stage. They suspected that Hua Tuo could not have made such brilliant achievements in abdominal surgery. When they had to admit that they had performed these complicated operations, they said that these surgical techniques were foreign, and even suspected that Hua Tuo was not from China. These ridiculous logics really confuse many people.
