Young people don't need to flaunt their talent — knowing when to hold back shows greater maturity.
Tips
usage
Slightly negative-leaning. The neutral version is 锋芒 (fēngmáng, sharp edge/talent); 毕露 (bìlù) means 'completely exposed', so the whole phrase says 'edge is fully on display' — usually with the implication that some restraint would be wiser.
history
The phrase appears in Hua Ershi's《汉衣冠》where it describes a high-ranking general whose talent is too visible — a recurring theme in Chinese culture, where 藏锋 (cángfēng, hiding one's edge) is often praised over 露锋 (lùfēng, showing it).
