发光

• 拼音: fā guāng
• 汉字拆解: 发 = 弓 + 殳 — to release, emit; 光 = 火 (fire) + 儿 (person kneeling) — a person illuminated by fire, light radiating outward

含义

To emit light; to shine; to glow. Both literal (objects emitting light) and figurative (a person or thing radiating exceptional quality).

Used in scientific, literary, and motivational contexts. The figurative use — describing a person who 'shines' through talent or character — is common in modern Chinese and social media. Collocates with 发光发热 (to shine and generate warmth, i.e., to contribute fully).
