I feel for you pal, this experience which you speak of is more common then people might think. In fact experiences like this are pretty much the norm if you ask me.

You are not the only one to experience such disdain, often Chinese teachers will treat their fellow foreign ones with this kind of attitude, usually spurred on by their own insecurity, and they see you as being the source of this.

I must admit I never had an experience this bad so all I can say is you had some rotten luck. Were you placed in this position by a recruiter per chance, or did you find it yourself?

Just another lesson to everyone thinking about coming to China or any other foreign country to teach. Do your home work, get the contact numbers of at least 3 other foreigners who currently work at that school, and research the hell out of them. This does not always mean things will go smoothly, but it sure helps.

You have my sympathy, I hope your next placement it a better one, it sure doesn't sound like it could be any worse.
