In the feudal society of ancient China, the degradation of women's social status was particularly revealed in prositutes whose misfortune and exclusion from the society deserved mercy. In the Yuan dynasty whose economy and trade flourished, prostitution prospered to meet the need of usinessmen who traveled a lot on business. Moreover, under the ruling of Mangolians in which political chaos was accompanied with gangsters bullying around, the intellectual were even inferior to prostitutes in social status. The circumstances greatly changed peole's previous concept of social ranking in which the intellectual were highly resected. Kuan Han-ching lived in the very low social class for long and because of his mercy on those prostitutes' miseries, he created the play "Chiu-feng-chen." This play probed into the social problems in the Yuan dynasty and tried to give those prostitutes who had been long neglected a respectable image of their character. By doing that, Kuan intended to arouse awareness of women in low class and hence shed a light on this age when prostitutes and the intellectual were highly disregarded. This is what lies in the very essence of this play.
