Toasting Culture and 干杯 (gānbēi): The most significant cultural aspect of 杯 is its role in toasting. The term
干杯 (gānbēi) literally means “dry the cup.” Unlike the casual English “cheers,” a call to 干杯 is often a serious invitation to finish your entire drink in one go, especially in business dinners or formal banquets. When toasting with a superior or elder, it is customary to hold your glass slightly lower than theirs to show respect. This simple gesture with a 杯 is a key part of social etiquette.
