Cao Hong
When Man Chong was serving as the Prefect (令) of Xu County (許縣; present-day Xuchang, Henan), he arrested some of Cao Hong's retainers who broke the law. When Cao Hong heard about it, he wrote to Man Chong, asking for their release, but Man Chong refused. Cao Hong then brought up the issue to Cao Cao, who summoned the official who was overall in charge to come and see him. Man Chong thought that Cao Cao wanted to pardon Cao Hong's retainers, so he immediately ordered their execution. Cao Cao was pleased and he remarked, "Isn't this what an officeholder should do?"
