I couldn't have put it better myself,Siverboy.
And we shouldn't forget that many Chinese parents place such a high value on education that they will make sacrifices,sometimes great,to pay extra for their children to be taught by FT's from kindergarten to senior middle school level.
That's what has driven the explosion in the demand for FT's in recent years.
The only way I can see it diminishing in the foreseeable future is if the Chinese language takes over as the language of international trade.I believe this is highly unlikely,for a variety of reasons,which I won't list here.
Once a middle school in a Chinese city of any size is known to have FT's by parents,it won't be long before others therein follow suit.A good opportunity for the likes of,dare I say it,Yuncheng IELTS,to make money!
