Beijing's Zhongguancun district is a den of hidden talent, brimming with capable people.
Tips
usage
Image: a dragon coiled out of sight and a tiger crouching low - both are powerful but unseen. Use it to compliment a place (a school, company, neighborhood) for housing impressive but unshowy people. Sister idiom: 藏龙卧虎, which is more common.
memory
盘 = coiled, 龙 = dragon, 卧 = lying low, 虎 = tiger. Two of China's most-feared beasts both deliberately hidden - the talent is real, just not advertised.
