There seems to be be some confusion about the company based in Yuncheng that has been treating foreigners badly, as reported on the Dave's ESL Cafe website.
If you go to the link immediately below, and read the thread, the culprit is clearly the English Village Language Training Center, not the Yuncheng IELTS School.

To find out more about the two two Yuncheng companies, you can access their websites by clicking on the two links below:

YUNCHENG IELTS SCHOOL link - http://www.ycielts.com/main.php

I'd NEVER EVER apply to the YUNCHENG EV LANGUAGE TRAINING CENTER for a post - teaching at an 'English village'/training center, you can get burnt out. Another couple of observations I've made irrespective of the complaints on Dave's thread about them and the wily Hangzhou recruiter they use are as follows: they are clearly a smslltime outfit that chooses not to operate as an equal opportunities employer.
