Cui Yan
In 205, after Cao Cao had defeated the Yuan brothers and taken over Ji Province, he wanted to recruit Cui Yan to serve as an aide-de-camp () under him. He told the latter, "According to official records, there are 300,000 troops under my command now. (Ji Province) is indeed a large province." Cui Yan replied, "The Empire is in a state of chaos and the Nine Provinces are divided, while the Yuan brothers fight among themselves and the bodies of the dead are scattered throughout the wilderness. The people have yet to see how your forces will bring benevolent rule and relief aid to them and liberate them from war and disaster, but now the first thing you do is to check the records for the numbers of troops and military equipment you've obtained. Is this what the people in this province expect of you?" Those present at the scene were all startled by Cui Yan's response. Cao Cao's facial expression changed and he thanked Cui Yan for his advice.
