Reciprocity as a Social Norm
禮注重相互往來和互惠。“禮”即禮制；“尚”即崇尚、注重。指人與人之間、組織與組織之間、國家與國家之間的交往互動，其中隱含著對等互惠的人際、國際關系思想。有時也表示用對方對待自己的態(tài)度和方式去對待對方，類似于“即以其人之道，還治其人之身”。
Etiquette requires reciprocity and mutual benefit. It refers to contacts and interactions between individuals, between organizations, and between nations. It implies equality and mutual benefit in interpersonal and inter-state relations. Sometimes, it also means that one should treat the other party in the way the other party treats you. It is similar to "Treating the other person the way he treats you."
引例 Citation：
◎禮尚往來。往而不來，非禮也；來而不往，亦非禮也。人有禮則安，無禮則危。（《禮記·曲禮上》）
禮注重的是往來互惠。我給人禮物而人未回饋，這是違反禮的；人給我禮物而我未回贈，這也是不合乎禮的。人做事符合禮就會平安無事，違反禮就會危及自身。
Etiquette values reciprocity and mutual benefit. It would go against it if someone who has received a gift does not reciprocate such goodwill. When one acts according to such etiquette, one will enjoy peace. Without it, one will cause trouble. (The Book of Rites)
