It's very great that you've tried the rest, and are returning to the best! Their are too many idelers and complainers teaching in China. These folks are getting their low pay too readily.
Contrast responsible schools in developed cities like Shenzen. They need professional teachers who are not workshy to serve the wealthy people of China.That's how to earn well, teach kids from rich families.
The folks that grumble are just jealous. For they know they can not encapsulate kids, and so never earn big bucks. Shame on them for their lying and inventing! Shenzen kids club is a wonderful school, I'm sure of it!
