Why shouldn't there be? Statistically speaking!
I note that you haven't even bothered to respond to Beth's post of the 12th, which went into more detail than my previous ones have in order to counter your presumptuous and bold generalization of a statement that all training centers in EFL are mismanaged.
That says it all! YOU have severely compromised your standing as an EFL expert with your inputs.
I'm not in the least bit surprised that nobody is backing you up on your stance re training centers so far. WHO WANTS TO BACK UP RUBBISH?.

Well, I never get any support and I talk a lot of sense!!

I did hear on the grapevine though that one supporter is currently lodged in an Australian Health Farm, drinking carrot juice and attempting to lose six stones. And the other one? He's in T's wardrobe with a mothball pinned to his nose. Hahaha! only joking. However, I really do hope they'll both be back.

As for training centres and all schools in China, you could get a good job with a good timetable, or you could end up with a right shit-hole to live in and a bad timetable, all at the same outfit. I know somebody working for a university in Shandong at the moment. He, this term, was given a timetable of 8 hours teaching; and a colleague gets 25 hours teaching- all for the same redemption.

If you work for an agent school come training centre, they could send you to a right old middle school dive which requires you to commute for 5 hours a day. Or you could get a nice flat right next to the middle school where all the students are gay and pleased to see you. So a good school for some can be a bad one for another. Turnoi himself will only be too pleased to tell you that the last time he left his lair and returned to China, through no fault of his own he ended up being given a bad deal at some university or other. We have since learned that the same conditions were not experienced by another FT at the same university. That was just bad luck for Mr T.
