樊城之戰
In the 14th-century historical novel "Romance of the Three Kingdoms", Hua Tuo heals the general Guan Yu, who is hit by a poisoned arrow in the arm during the Battle of Fancheng in 219. Hua Tuo offers to anaesthetise Guan Yu, but he simply laughs and says that he is not afraid of pain. Hua Tuo uses a knife to cut the flesh from Guan Yu's arm and scrape the poison from the bone, and the sounds strike fear into all those who heard them. During this excruciating treatment, Guan Yu continues to play a game of weiqi with Ma Liang without flinching from pain. When Ma Liang asks him later, Guan Yu says that he feigned being unhurt to keep the morale of his troops high. After Hua Tuo's successful operation, Guan Yu allegedly rewards him with a sumptuous banquet, and offers a gift of 100 ounces of gold, but Hua Tuo refuses, saying that a physician's duty is to heal patients and not to make profit. Although Hua Tuo historically died in 208, a decade before Guan Yu fought at the Battle of Fancheng, this story of him performing surgery on Guan Yu has become a popular artistic theme.
