Xun Yu
Cao Cao ordered Hua Tuo to be his personal physician – a job Hua Tuo resented. In order to avoid treating Cao Cao, Hua Tuo repeatedly made excuses that his wife was ill, but Cao Cao discovered the deception and ordered Hua Tuo's execution. Xun Yu, one of Cao Cao's advisers, pleaded for mercy on behalf of the physician.
