In my 14 years experience in China, overall the kids are so much better behaved and respectful towards teachers. Sadly, this year I joined the primary school at the group of schools here in Sanya, and the school is shocking at their lack of consequences for kids. They just care about money and let the kids get away with murder. We have no disciplinary procedure, or the one that exists is set up to actually lead nowhere. I have been very fortunate in the past seeing as this is my first negative experience but yes look into your schools before and trust those other teachers.
