After my last six years teaching in China, I have found that for me, an experienced original can only get a job easier by applying to public schools. Most of the private schools are racist in a way. Such as Capital English School in Zhongshan. They know what an experienced non-native can do, but insist on 'White, Caucasoid' to attract more students. They didn't want me to leave, yet they wanted to pay me less and do more work for them. Whereas the public schools usually are more professional and prefer experienced teachers and understand what a less effective, 'Native, non-professional white face' can do.
