And a GAC Instructor is not even a real Lecturer's job since GAC is normally not taught at unis in China but at private schools or "schools".

True, Turnoi.
I'm glad you've elaborated for the benefit of the board's readership.
In fact, as you and I know, the GAC courses in China have been discussed at length on the board before. Those readers who wish more info regarding them can use the board's search engine.
My advice is not to work at a GAC centre in China. I'll leave it at that.
