'Zìzhùcān' literally means 'self-help meal' — 'zì' (self), 'zhù' (to help, assist), and 'cān' (meal, food). Together, they describe a dining format where guests serve themselves from a variety of dishes displayed on counters or tables. Unlike traditional sit-down meals with fixed menus and waiter service, a buffet emphasizes choice, independence, and often all-you-can-eat pricing.

This term is widely used in restaurants, hotels, corporate cafeterias, and even wedding receptions across China and other Mandarin-speaking regions. It reflects modern urban lifestyles valuing convenience and personal preference. While the concept originated abroad, 'zìzhùcān' has become fully naturalized in Chinese — you’ll see it on signs, menus, and food delivery apps. It’s neutral in register and appropriate for both casual and semi-formal settings.
