酔看青楼笑
[zuì kàn qīng lóu xiào]
A rather old saying which translates as drunkenly watching a Qinglou (ancient term used to describe places for singing dancing drinking prostitution entertainment), and laughing out. It's mostly used when somebody lives an idle and indulging life and finds everything amusing despite all difficulties around the person. It's very likely inspired from ancient Chinese poems and stories set in such scenes.
