I myself have put other FT's in the know- GO TO YUNCHENG IELTS-IT'S A GREAT PRIVATE SCHOOL!

Good advice, but let's make it clear that that employer is a private employer who supplies mainly local public senior high schools with expats to teach basic oral English. So, if you work for IELTS School of Yuncheng, you'll most likely be teaching non-IELTS English in the public sector aided by a teaching assistant allocated to you by the private employer.
BTW, I think it's generally advisable to teach at a public school when in China, even if said school is out in the boondocks.
