That was pretty to the point!

It is, as others have pointed out completely true that Chinese employers and more importantly parents/students i.e. customers want white faces.

A lot of recruiters and schools who use them care so little about the teachers they place in schools that they will land non-white teachers in a position where they aren't wanted from the off.

A black (British born) friend of mine was placed at a private language school in China by an agency. He arrived in Beijing and was sent by the agency to the school a few hundred miles away. When he was met at the train station by the DoS it was obvious there was a problem. Within a couple of hours they'd told him they couldn't employ a black teacher and packed him off the next morning on a train back to Beijing. After a week in limbo he decided to go back to the UK at considerable expense to himself

These guys are at least saying upfront that you won't get equal treatment but still i would want to go straight to the source i.e. the school and talk to people their to be really sure that they knew they weren't getting a white teacher/foreign concubine.

Any school that really believes that in the long run it is the appearance of teachers rather than their teaching quality that matters is worth avoiding whether you are black, white, Asian or a green alligator (lol!)
