If you post some details of your life on a public discussion forum then you should expect people to respond in different ways.

I was not judging you, i was judging your approach, while in fact giving yourself, and any others unfamiliar with Chinese schools, advice. I was trying to assist you, but for some reason you can't see it, or, perhaps do not wish to. Where does quarrelling come into it? This is healthy debate, about what techniques or approaches may help foreign teachers in China prosper in their employment.

Yes, your topic, is about how to get good release letters; I accept that. However I don't think that there is any harm in letting yourself and others who may be contemplating coming to teach in China, that your approach is quite short-sighted, and unfair to Chinese students. Many FTs would like to find a good school and stay there if they're happy. Your approach is only ok if a teacher is happy to keep moving from job to job all the time, content to sell Chinese students short, and willing to be false to those that they wine and dine, if they don't really like them. Also such an approach would need an individual to be ready to swallow a lot of pride.

I wanted to let those who are considering coming to teach in China, know that there are much better alternatives than your approach.
