What I do tend to find is that any school in China with a name that includes words like Oxford or Cambridge etc, is most definitely not official. There’s the exception of a few legitimate officially licensed international schools like Harrow in Beijing, but you would probably have to be a really shit hot teacher to get employed there.

Let me put it this way... They will never advertise a vacancy on this website or Dave’s ESL etc. And they will give you a Z-Visa, lol.
