Yes this is correct. CZZ is really a kind of agency that assigns teachers to schools. Every teacher I know about will always find themselves eventually let go from any given school. You may be there 2 months or 4 months but eventually you will get a call saying they didn't like you. Usually just any standard made-up reasons. If you are a spontaneous teacher then complaints you didn't follow the book. If you are a by-the-book teacher then they didn't like you only read from the book. By 'they' means nothing. Anyways, the point is you won't need to worry as they will assign you to another school where it turns out another CZZ contractee just so happened to leave because that school didn't like him. So they will transfer you (see they're nice) but yes you WILL change schools. This will nullify something in your contract yes. You are also correct that many very often the school itself, principal or anyone in the school will actually know about this. That school might even be told that you (the teacher) in fact decided they didn't like that school and wanted to transfer or leave. (decieving both parties). You know the sad thing about CZZ is that a lot of sincere and really good well-intended teachers arrive (almost always 1st timers totally naive of China which is who CZZ wants) but in theory there are a lot of schools and kids and teachers who could really benefit and have a great experience. So it surprises me the Zhengzhou goverment allows CZZ to keep destroying, scamming and fucking up schools and teachers with their barely-legal scam monopoly on things in Zhengzhou? CZZ shames China, gives innocent 1st time visiting foreigners a horrible impression of China and can you just imagine that they go back home and CZZ and how they were abused, disrespected, treated by little men .. that THIS is their idea of what China is like??
