When combined, 发火 (fā huǒ) literally means “to emit fire” or “to start a fire.” This creates a powerful and intuitive visual metaphor for a sudden, uncontrolled burst of rage erupting from a person.
In Chinese culture, great importance is placed on social harmony (和, hé) and maintaining “face” (面子, miànzi), which refers to one's reputation and social standing. Publicly losing your temper, or 发火 (fā huǒ), is often seen as a significant loss of self-control and can cause both the angry person and the target of their anger to lose face. This contrasts with some Western cultural contexts where “expressing your feelings” or “letting your anger out” can sometimes be viewed as a healthy or assertive act. In China, especially in professional or formal settings, a public display of anger is typically viewed as a sign of immaturity and a failure to maintain emotional composure. While everyone gets angry, the cultural pressure to avoid an outward explosion (发火) is generally higher. The ideal is to remain 冷静 (lěngjìng), or calm and cool-headed, even when provoked.
发火 (fā huǒ) is a very common, informal term used in daily conversation.
