The Eastern Han scholar Sima Hui never spoke of other people’s faults. Whatever he heard, he answered “Good.” Asked how he was, he said “Good.” When a man told him that his son had died, he said “Very good.” His wife scolded him. Sima Hui replied: “What you say is also very good.”
The Ming writer Feng Menglong, who tells the story, says that the expression 好好先生, Mr. Good-Good, comes from it. Dictionaries define it as a person who does not ask what is right or wrong and only wants peace.
