'Gān bēi' literally means 'dry cup'—'gān' (dry) and 'bēi' (cup or glass)—and is the standard Chinese expression used to propose a toast, equivalent to 'Cheers!' in English. It signals that everyone should drink their beverage (usually alcohol, but sometimes juice or tea at formal or family gatherings) in one go, symbolizing sincerity, goodwill, and shared celebration.

This interjection is deeply embedded in Chinese social customs, especially during banquets, weddings, business dinners, and holiday reunions. Unlike English 'cheers', which can be said while merely raising the glass, 'gān bēi' typically implies actually finishing the drink—or at least taking a substantial sip—as a sign of respect and enthusiasm. It’s often accompanied by eye contact, a slight bow of the head, and sometimes clinking glasses. The phrase reflects Confucian values of reciprocity and collective harmony, making it more than just a casual exclamation—it’s a ritual gesture of connection.
