青楼菇凉红尘骚年
[qīng lóu gū liáng hóng chén sāo nián]
'The girl in the pleasure quarter and a young rake in the dust', it depicts a relationship or an environment. '青楼' originally meant the residence of beautiful girls and later referred to a brothel. But nowadays this word doesn't imply so much negative meaning, and here may express one's free life. Meanwhile, 红尘 means the mortal world full of temptation and 骚年 is slang for young man. So together, the whole ID represents an active participation in secular society or just means that users like literature of ancient China.
