In 219, during the Battle of Mount Dingjun, when Xiahou Yuan led troops to attack Liu Bei's camps at Dingjun and Xingshi mountains, Fa Zheng suggested Liu Bei to strike the enemy. Liu Bei ordered his general Huang Zhong to lead his men on a charge down the mountain towards Xiahou Yuan's forces, with war drums beating in the background. Huang Zhong defeated and killed Xiahou Yuan in the midst of battle.
