I haven't any knowledge about the currant situation in these areas about if there continues to be employment opportunities there for foreigners as foreign teachers or the recent phenomenon of hassle from the local police. But with the recent puniitive changes to the visa laws, no rightminded illegal will teach there, and those who have working visas won't either. China continues to shoot itself in the foot, that's how stupid the legislators are, and have been in the past. Or will the situation change in the future? Being an optimist, I's be pretty sure it will.
I expect that ielts school will rise from the ashes, and ev will be ok too. Money will talk if channelled into the right places!
