Hey Guys; Whats the problem? The answer is right in front of you. Maria, lily, Kim, or any other procurer will tell you that if your not satisfied when the Girl shows up, give 100rmb(for taxi), and send her on her way. Talk to the procurer and tell them what you want, and believe me they will try to make you happy. If you aren't happy, they won't be happy because they won't get their cut from the Girl. It's not rocket science, think with the head on your shoulders and screw with the one between your legs. Remember, the body doesn't have enough blood for both heads to function at the same time.

Personally, I exchange English lessons for sexual favors, but remember this is the land of barginning!
The guard thinks the lovely ladies stopping by at 10:00 or 11:00pm are my "students" and are happy to give them directions to my apartment.

Have fun, and Happy Spring Festival, and Chinese NewYear!
