What is “Keqi”? 什麼是「客氣」?

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.”
Besides, Chinese seldom express what they think directly and they prefer a roundabout way. Neither show their emotions and feelings in public. They rarely greet people with a handshake, though it is very popular among foreigners, say nothing of embracing or kissing when greeting or saying good-bye. Consequently, it is better not to behave too carefree in public, even though you are well-intentioned. Also, it is advisable to be fairly cautious in political discussions. Do not particularly push yourself forward, or else you are unwelcome.
To sum up, do in Rome as Rome does, but you need not worry avout these cultural barriers since most Chinese are hospitable and amiable and will not mind your nonproficiency.

客氣並不只是包含考慮周詳、禮貌文雅和舉止端詳,還表現在謙遜和謹慎。對自己或者自己的圈內人表達的傲慢或者自誇都是不禮貌的。表達的時候,通常要以否定的形式,比如「不要客氣」,意思是說「你不必對我這麼關心、禮貌」或者「不用謝」。
此外,中國人很少直接表達自己的想法,而喜歡用旁敲側擊的方式。從不在公共場合表現自己的情緒或者感覺。儘管在西方握手的見面禮非常普遍,但在中國這樣做的人還不是很多,更不用說見面和道別時的擁抱和親吻了。因此,即使你是出於好意,在公共場合也不要表現的太自由自在。同樣,在政治話題上保持相對謹慎也是明智的。不要太特立獨行,否則你將是不收歡迎的。
總之,入鄉隨俗,但你也不必對這些文化障礙擔心,因為大多數中國人都是好客和和藹的,他們不會介意你的不熟悉。
