Say to Xiu: "Do you understand?" A: "Solution." Wei Wu said, "You have nothing to say. Let me think about it. " After walking three miles, Wei Wu said, "I found it."

Cao Cao asked Yang Xiu, "Do you know what this means?" (Yang Xiu) Answer: "I know." Cao Cao said, "Let me think about it first." Thirty miles away, Cao Cao said, "I already know." Yang Xiu was ordered to write down what he knew separately. Yang Xiu wrote: "Yellow silk and colorful silk are written as' unique'; Young woman, girl's meaning, written as' wonderful'; Grandson, daughter's child, wrote' good'; Mortar, the device of collecting five spices, written as' ci'; This is the meaning of' wonderful words'. " Cao Cao also wrote down his own ideas, just like Yang Xiu's, so he praised him and said, "My talent is not as good as yours. It took me 30 miles to understand (the meaning of the inscription). "
