客气 keqi

Keqi not only means considerate, polite, and well mannered, but also represents humbleness and modesty. It is impolite to be arrogant and brag about oneself or one's inner circle. The expression is most often used in the negative, as in buyao keqi, meaning "you shouldn't be so kind and polite to me," or "you're welcome."

客气并不只是包含考虑周详、礼貌文雅和举止端详，还表现在谦逊和谨慎。对自己或者自己的圈内人表达的傲慢或者自夸都是不礼貌的。表达的时候，通常要以否定的形式，比如“不要客气”，意思是说“你不必对我这么关心、礼貌”或“不用谢”。
