Excellent post,Adrian.I've also been through what you've been through working for 'an international college' in China. It's astonishing how so many Chinese parents can be taken for a ride so easily by their own kind when you contrast their great and unwarranted distrust of louwai.So I don't feel sorry for the victims.
If you'd continued to work for International College,Huangshi,you'd have been assisting the director and his crooked staff to perpetuate their scam.Good on you that you stood up to them and cast their ropey job aside.I take it you'd found a decent one before you did so!
