青楼净身
[qīng lóu jìng shēn]
In traditional Chinese culture, 'Qing Lou Jing Shen' means 'Cleanse body in Brothel'. This might be an allusion to brothels or courtesans from ancient China where some scholars cleansed their mind and spirit despite the seemingly inappropriate place of cleansing body. However it can also be misunderstood as being controversial in modern western world.
