Treatment must be divided into internal and external surgery, and there are not many wonders in the world.

The divine power is only Guan Yu, and the holy hand can cure Hua Tuo.

This is a poem written by Luo Guanzhong, the author of China's classical literary novel Romance of the Three Kingdoms, which quoted later generations to praise Hua Tuo, a famous doctor at the end of the Han Dynasty, for scraping bones and curing poison for Guan Yu.
