First mistake: Getting involved with the teaching of Chinese teachers. Mind your business unless you like bouncing from school to school or program to program. You're trying to make policy with downtrodden fools and you will always come out the loser. Put the blinders on and collect your check.

Definitely. Do your 16 classes and enjoy the free accomodation. Trying to change things is useless with the Chinese. If you can't stand it leave for shores anew or go home. The chinese are set in their ways, beyond doubt.
