I haven't posted the names of the foreigners as I wish to preserve their anonymity. However, the names of the 9 schools/colleges/universities involved are those below. Some of them will be bad employers to work for. Further googling will be necessary to possibly get further relevant information in this regard. The list is indeed useful!

1 Asahi text language education training school

4 Wuxi Institute of Technology

5 Qingdao Hao Foreign Language Training School
