Well there is the problem right there, you went to Jilin province. It is widely known as the absolute worst province in China for a FT to work. You are not likely to find a more corrupt education system in regards to teaching English anywhere else in China. I think I have read more horror stories coming out of Jilin than anywhere else. If you see an ad for a school in Jilin, my advice is just steer clear, in this case better safe than sorry is the besr course to take.
