Wallace has stated the following re Yangzhou College of Environment and Resources:

It is not a school for someone who wants to teach. It's a school for backpackers and people who otherwise wouldn't have a paycheck or a roof over their heads.

What he said has reminded me of how very many educational establishments like that operate in China,where it's possible for foreigners with average or below average English to make a good living by entertaining their students.
I can recall clearly the following situation at a middle school in Shaanxi a couple of years ago:a foreign colleague of mine from France admitted that he knew nothing about teaching English.He also said teaching in China was much preferable to fruitpicking back home,which he described as poorly-paid backbreaking manual labour.His penultimate comment was that he could live very well off his teacher's salary here while having plenty of free time to enjoy himself.Finally,he vowed never to leave China.Last I heard,he'd married a beautiful Shaanxi girl,10 years his junior!
I reckon he will always be able to find a job at one of the many educational establishments here that need no more than a white face with English that barely qualifies as literate!At the end of the day,he shouldn't be blamed for taking part in the charade that goes by the name of education here.After all, he's raised his standard of living by doing just that,and he should not be criticised for having found his niche in a less than adequate system of education!
