Instead of telling him all that, the Chinese let him rot in some rat-infested hotel and put him through other indignities until the the teacher got fed up and ran off.
No, I don't think that's really the case:

Turnoi, tt can be the case - I heard the sad story from a westerner who had frequented night clubs at weekends, and someitimes not returning to her flat the next morning, getting called a 'dirty stopout', and having her acommodation changed for the worse.

It's not a good idea to club in China as a foreign teacher. You'll be looked down upon! I think night clubs and KTV's are boring places to hang out, and should be avoided by teachers. Besides, there's always the risk of a violent incident at those drinking places, even involving another foreigner. Drink affects some people very badly, causing them to want to fight!
