《论衡·卷二十·须颂篇》
一个人有了高尚的品行，有的人对他颂扬得完全符合实际，有的人想称赞他却说不出来，有的人却认为他不好而不愿说一句称颂的话。
人有高行，或誉得其实，或欲称之不能言，或谓不善，不肯陈一。
A person has noble character, some people praise him completely in accordance with the facts, some people want to praise him but can't speak, some people think he is not good but would not like to say sentence commended words.
