Robert,
Thanks for posting the information regarding schools/employers in China to avoid. Poster "Silverboy" has developed the China "Hall of Shame" blacklist posts (which inspired me to create one dedicated to dodgy employers/schools in Korea). If you are serious about developing a China "black list," I suggest that you collaborate with Silverboy as he has done much of the work already -- and putting together a comprehensive list for China is a huge understaking.
Good luck, and thanks, again.
STAY FAR AWAY FROM THE FOLLOWING :
1. New Dynamic Institute(NDI), Chengdu, Sichuan Province.
2. Star International Education, Changchun, Jilin Province.
3. Y.E.S English, Changchun, Jilin Province.
....To be continued.
