Hadler,the reason no one mentions good schools is because most language schools in China (and the rest of Asia for that matter)really are crap. Most of the people who own and manage Chinese language schools and training centres, have no morals, ethics, or values. There are people in forums like this who will try to tell you otherwise, however they are wrong.

I like China,and mainland Chinese people very much, but you wont't find many nice Chinese people (or Westerners) working at language schools.If you want to teach in China, good luck, but you should be VERY CAREFUL.
