Through additional research, I have found that prostitutes are often linked with other groups; each in pursuit of economic prosperity.  Prostitutes would often work with gangs in China.  Gang members would select girls to work in Hong Kong for low wages to appeal to the locals, and when they returned back into the PRC, the gang members would take their money and then turn them into the authorities.  Gangs never had an issue finding new women to send to Hong Kong, because many females were interested in earning a quick dollar. 

In addition, I read a source about a college student who worked as a prostitute to make it through school.  She made more money as a prostitute than in any other job.  However, she worked in a hotel, in which her manager knew her other job, and would offer her out to clients.  She was often ranked as a number one because of her education.

My primary source also talks about working as a prostitute in a bowling alley.  It appears that many other businesses do not care about prostitution, especially if it provides them with further income.   Economic pursuit appears to be the main goal of many chinese, and they often do not care how they achieve their goals.  One source discussed the advantage of legalizing prostitution in China.  If prostitution was legal then the government would be able to not only regulate the amount of STDs spreading throughout the country, but also be able to control the amount of women doing it.
