I personally don't usually read these boards but a friend brought it to my attention. So here's my opinion.

Firstly, I would doubt whether the author has been anywhere near Yuncheng in the first place.

The requirement about a degree is more than likely correct but to specify a four year only degree is quite absurd. Its not just the UK that has three year degrees either.

I have never worked for EV or IELTS but I am familiar with the area. I have heard various stories about both of them, some good, some bad. At the end of the day wherever you work you are going to endure some of what the serial complainer is spuriously portraying.

IELTS are pretty much running on life support at the moment but they have been given the green light to resume their business model so I am also sure they will pick up some of their old contracts again soon. I just guess they will be super careful about who they hire from now on. Who they employed previously did get a lot of schools/parents backs up in the past.

EV have lost contracts too, they also have lost teachers, but as usual they will start their annual recruitment campaign soon. They do have a tendency to shift teachers around at a moments notice but thats part and parcel of signing up with such an agency. They shed a long term teacher recently citing age as the reason, in fact it transpired they simply didn't want to pay the extra insurance. Very short sighted actually as the school where the teacher had been loyal for a considerable amount of time has fallen out of favor with EV and will be ditching them and dealing with things solo soon.

Yuncheng like anywhere else has some good and bad points. It depends on you as a person. I do know, however that certainly in the last year a lot of people have left (either gone home or moved onto pastures new) so the number of foreigners is considerably lower than previously.

Just like everyone else reading this, I have had to deal with the endless beurocracy with working visas, and yes it is frustrating but I have just had to be patient. I certainly have never encountered anything on the level you present here. If all your documents are authentic then I don't see why you would be worried.

To suggest that any person avoids a city or province and heads to the big smoke just because the author may have had some unfortunate incident is at best misinformed and at worst misguided. I would take it with a pinch of salt.
