Hi Sinkawhorean,
Thanks bro for the clarification, explanation and some proof. You have to understand the standard of living is different in China. A normal restaurant working makes around $1000RMB. To make above 3000RMB is consider very good especially if someone is so young. If she goes freelance, ( like no mamasan or pimp to take a cut.), all she needs is 4-6 customers a month and she will be fine to pay the bills. For now, I suggest she find a real job for a month or two. She can work part-time escorting clients during her days off or after work. Nevertheless, since it seems like you got a good responds from the forum, it doesn’t look like she will have a problem now.
Note, the problem I found out majority makes good money but send most of it back home to support parents and other family members. They go into this line of work thinking to make quick money. Most would do fine financially if they didn't send anything home.
You might want to ask “Jing Jing” was she sending money back home? Sorry to be so skeptical and I know you want to help her.
Just another side note, try not to feel too sorry for the pretty MM’s because some can make serious money. Majority makes more than the average person. This is not only in China but anywhere in the world. For example, in China I have heard 12,000 to 15,000RMB and more a month is not uncommon. The ones that are not that pretty are out the door in less than a month and often go back home.
