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!

What I do in my own spare time is none of their business and if it is the case that an employer looks down on me for partying, they are simply not worth working for.

F**k, I even used to go partying with one of my old bosses (outside of ESL, mind). He pretty much taught me that, partying is ok, as long as you do it at the appropriate times and understand that you'll still be expected to get to work on time and function as normal, even if you got absolutely wasted the previous night. Therefore, you have to think carefully before you choose to go out on a work night.

However, he did tell me that sometimes, you need to go out drinking in China as part of your job and that certainly proved to be true. Baijiu banquets are a very common part of business here, plus they will often take you to a KTV afterwards.

Also, if you aren't capable of avoiding fights, you are pretty much an idiot.
