What city? In most places, if you stay at the correct hotel, some GREAT P4P ladies will find you... a bit like shootin' fish in a barrel. In other cities or at the wrong hotel, it will be much more difficult.
A "nice" traditional Chinese girl will not likely be out by herself, more likely in a group of friends, and not very likely to say more than a few words to a stranger who she knows will be gone in 2 weeks. If you are working there, IMHO, someone WILL introduce you to a friend or relative. Treat it like any other first date in the US... dinner, movie, night market, drinks, etc... and if you like her go a bit slow and you might be rewarded in kind. (And you also may not be... so I suggest also trying P4P quielty also... but if you do resist the urge to tell your co-workers, as if they know this they will NOT introduce you their their friends/relatives. LOL)
