if you know how to read chinese website. Try
www.zhantai or
www.naalee and you can find quite a number of freelance or mamasan.
Tried one call Cici number 13641247976, she has on hand a few girls from Sichuan and some other part of China.
The girl she sent is from Sichuan, looks about 6, but has a good figure and know how to BBBJ. Get excited easily. Good quick relief where you do not need to go out of your hotel room.
Can try again.
