‘救火’ literally means 'to save fire', but in Chinese it actually means 'to put out a fire' — the character 救 ('to rescue/salvage') here conveys the sense of rescuing people, property, or a situation from the danger of fire. Though the characters suggest saving fire itself, the phrase is idiomatic: it emphasizes urgent intervention to stop destruction.

Beyond its literal meaning, ‘救火’ is widely used figuratively to describe rushing to handle any sudden, critical emergency — like fixing a system crash, calming a public relations crisis, or responding to a medical emergency. This metaphorical use is common in workplace and news contexts, where it implies reactive, last-minute problem-solving rather than prevention. The term carries a slightly negative connotation when used figuratively, suggesting poor planning or lack of foresight.
