Battle of Fancheng
Cao Cao's general Yu Jin was captured by Guan Yu during the Battle of Fancheng and was held captive in Nan Commandery. After Sun Quan seized control of Nan Commandery, he released Yu Jin and treated him with respect. One day, when Sun Quan travelling on horseback, he asked Yu Jin to ride beside him. Yu Fan saw that and shouted at Yu Jin, "You're a surrendered prisoner-of-war. How dare you ride side-by-side with my lord!" He wanted to hit Yu Jin with his horsewhip but Sun Quan ordered him to stop. Later, when Yu Jin joined Sun Quan in a feast with his subjects on board a ship, he shed tears when he heard music being played. Yu Fan mocked him, "Are you pretending to be pitiful?" Sun Quan was very unhappy with Yu Fan.
