If you work for them you will end up hating China and hating all Chinese people because of your experience. Which would be a shame because you can meet good people here if you work at the right public school or university. Do not even consider working for any private school.

I think you should do yourself a big favour and keep right away from EF.

I'm toad in a hole, and I think that private school owners in China are nothing but greedy and lazy and corrupt toads!

They will retreat back into dirty holes!
