Haohao Xiansheng
Sima was known to never mention others' shortcomings or flaws. His reply to both good and bad news would always be "hao" (好; literally: "Good / Yes"). When someone asked him, "How are you?", he replied, "Good." When somebody told him that his son had died, he said, "Very good." His wife chided him for that, saying, "Everyone sees you as a person of good moral conduct, so they're willing to tell you their problems. Why do you say very good when someone tells you that his son had died?" Sima replied, "It's also good to hear what you've just said." This gave rise to the Chinese idiom haohao xiansheng (好好先生; literally: "Mr. Yes").
