I can tell you what the city is like, I have lived there and visited there many times, and still have friends there.

You can email me at the email included, if you would like.

As for the school, I would avoid it and take a public job. The area is no doubt beautiful, but teaching kids like that, in a only for profit environment, esp in the humid semi tropical summers, would prove draining and frustrating.

Zhaoqing is a nice place, if you have a relaxed public job imho.
