that I have been trying to get an answer to for quite a while now.
When you visit San Ya (Hainan), you always see those (mostly) Russians having a Chinese female companion. Who are these girls? Who organizes such operation? -- I have not seen a foreigner without company. How do they know where to find the service? Do all these girls speak Russian?
If your Hainan companion is not part of this kind of service, then just ignore my questions.
