Question: what does diao mean in chinese?
Answer: The term for this means “idiot” or “moron,” and comes from an ancient Chinese story. In Ancient China, the square hole in copper coins was used to string them together. 1000 coins stringed together was a “diao.” Half of a diao, or 半吊子 (bàn diào zi) was used as slang to talk about someone who was inadequate.
