I agree with Fish. China has too many people who think that they are an English teacher just because they are from a native speaking country of English and they are trying to teach English. There are too many people here that are not doing a good job. So when a thing like this happens, the authorities look to tightening the reg's. So qualifications are looked at and it is decided a degree is a must. This does not mean that a person is any better as a teacher but it is the point where people start to look at. Yes there are good teachers here with no degree and bad teachers here with a degree. That is life!
