‘口粮’ literally combines ‘口’ (kǒu), meaning ‘mouth’ or ‘person’, and ‘粮’ (liáng), meaning ‘grain’ or ‘staple food’. Together, it refers to the basic daily food ration needed to sustain one person—emphasizing subsistence, not luxury or variety. Historically, it was used in military, agricultural, or famine contexts to denote officially allocated or minimally sufficient food per person per day.

Today, ‘口粮’ is still used in both literal and figurative ways: literally for survival rations (e.g., emergency supplies or animal feed), and figuratively to describe essential, no-frills provisions—like a student’s budgeted meal allowance or even digital content one consumes regularly (e.g., ‘追剧口粮’ — ‘drama-watching rations’). It carries a pragmatic, sometimes slightly austere connotation, implying necessity rather than choice or abundance.
