However, it doesn't change the fact that people with a work history at training centres, especially in China, do not qualify for jobs art decent and reputable schools

Except that's not a fact and saying that qualified teachers who have chosen to spend time working at a TC or a private school cannot qualify for jobs at reputable or decent schools is just about the most ludicrous thing you've ever said (and it's a long list to chose from!)

You are simply being obstinate for the sake of argument, anyone can see that. What a childish thing!
