I work in Dongying, the same city as Golden Bridge school. I know of two teachers who were actually advised by their recruiting company to do the midnight run because the school was so bad. They didn't pay them properly or anything.
I would have to agree with you- working in China is difficult and often not worth it. Out of all the foreigners I've met here, who work in different places around China, not many like who they work for or where they work.
