Well "Suzhou Steve," your post is a perfect example of the "pot calling the kettle black." Your writing, spelling and punctuation leave a lot to be desired; especially from one who chooses to judge others. My suggestion for you is that you take advantage of the web to improve your English skills before assuming that you can teach them to others. Or, as an alternative, confine yourself to just teaching Oral English - a job for which the interest will never wane in China and you can continue to pass yourself off as a qualified English teacher.
Any further advice I have for you would be in the same context of not judging others before judging yourself, but I fear it would fall on deaf ears, or blind eyes as it were.
