Hi Lyn,
Yes, all true, but a little too negative for my experience. I spent more than three years teaching in China and will definitely go back. The positives certainly outweigh the negatives in my view. Most of my time there was at one very big public school so maybe I just got lucky, although I taught at summer camps with teachers from other parts of the country and most were happy. Love to hear from you if you want to email me. I have lots of info, both positive and negative, photos, etc that might help you.
