Usage Notes
When used figuratively, 发火 usually describes a sudden emotional outburst, often implying a loss of control. It is more informal and can be used to describe both minor irritations and stronger anger. Avoid confusing it with 生气 (shēngqì), which is a more neutral term for 'angry.' 发火 often carries a nuance of explosiveness.
Register and Tone
发火 is informal and commonly used in spoken Mandarin. In formal writing, especially about machinery, it retains the literal meaning. When describing emotions, it is casual and sometimes slightly humorous or critical.
