I can't find your post in reply to mine re Yuncheng IELTS School.

Anyways, I can recall its gist:

First point, if you've a Chinese spouse you can renew your L visas at the PSB office of your spouse's hometown. You can get at least a 180 day L visa, and possibly a 360 day L, according to the attitude of the PSB there. My zero entry L's cost me 160 Yuan each. No need for visa runs! I believe the spousal Residence Permit is a five year one, not one for two years. It's not so easy to get for some Westerners.
Second point, River's company can't be compared to a training center nor a private school for most of his foreign teachers - they're teaching in the public sector on behalf of River.
Third point, River's t/a's have the best interests of the company at heart. They are different from staff supplied by a public school to assist Westerners! Such staff would shop their FT's shortcomings to the headmaster of the school. River's t/a's don't do that, though they'll report shortcomings to River.
Fourth point, I was on 5,000 a month for 16 classes a week in counties. The only negative I can mention is no pay during the main holiday between the two semesters of your 10 month contract.
Fifth point, River's foreigners were earning basics of 4,200 - 6,500 a month last term. Yuncheng-based staff were teaching 20-22 classes a week. And they were getting extra work through River. I know this as Nicole, the receptionist at the company HQ goofed by sending the salary doc for the whole staff to every FT! I guess this will lead to fireworks when contracts need renewing!
