I worked at Huijia a few years ago and generally liked it, though I didn't teach in IB. Unfortunately, though, I have to agree with some of what was said in the previous posts. The primary school has a good rep but the IB and other departments have their problems. There's a small minority of students that attend Huijia who are serious and work hard, but I think the majority of them have no intention of doing anything other than playing computer games. Also, the environment at the school is not positive or conductive to serious learning.

Hope this helps. Good luck!
