‘饭碗’ literally means 'rice bowl'—a simple container for cooked rice, a staple food in Chinese meals. Historically, the rice bowl symbolized sustenance and daily nourishment, making it a natural metaphor for one’s livelihood or job, since employment provides the means to eat and survive.

In modern usage, ‘饭碗’ almost always carries this figurative meaning: a stable source of income or occupation. It often appears in expressions about job security (e.g., ‘保住饭碗’ – 'to keep one’s job') or unemployment (e.g., ‘丢了饭碗’ – 'to lose one’s job'). While the literal sense is still understood—especially in rural or traditional contexts—the idiomatic use dominates everyday speech, media, and workplace discussions.
