Abstract: In the depravity romances of Shanghai, the relationship between prostitutes and their clients changed from the previous subordinate relationship into financial relationship, which made the prostitutes independent in economy, and gain relatively free space.The traditional ″gifted″could bot become the ideal target of the prostitutes in modern Shanghai brothel, but were arbitrarily trampled by them;at the same time, the undisciplined traders may not be able tobe treated sincerely by prostitutes.The new changes of male-female relationship in brothel forced the men coming to brothel for "pleasure" to change.So the depravity romances of Shanghai constructed a completely new male charm system——"Gong Jia".
