In a flash of anger she walked out of the company.
Tips
usage
Reads literally as 'under one anger' — a four-character set phrase used adverbially before a verb to describe an impulsive action driven by anger. Always indicates a single triggering moment, not sustained rage.
memory
Think 一 (one) + 怒 (anger) + 之下 (under): 'under a single burst of anger.' The 之下 frame is also seen in 情急之下 (in a moment of panic) and 无奈之下 (with no choice but to).
