聪（cong）
Name meaning
聪 (cong), traditional 聰 (Cong), means perceptive hearing and clear discernment. In a name it should suggest intelligence that listens, notices and judges carefully. The strongest reading is not cleverness for display, but alert understanding joined with moral restraint.
Practical naming use
Use 聪 (cong) when the name should feel bright, observant and quick to understand. It suits study, analysis, music, language, mediation or any identity where listening matters. Because the character can sound like simple cleverness, pair it with sincerity, steadiness or humility.
Pair 聪 (cong) with a balancing character such as 聪文 (Congwen), 聪安 (Congan) Cong'an, 聪诚 (Congcheng) or 聪谦 (Congqian). These pairings turn intelligence toward learning, calm conduct, honesty or humility.
聪文 (Congwen): Cong contributes intelligent, quick-eared; Wen adds culture, writing.
