The main goal for a private school teacher in China is to follow chinglish lesson plans, and make loads of money for the boss. Your or you're level of English is more than sufficient to achieve that. Yes, you should have your living area inspected regularly. If I were in charge I would inspect your shoes hands and nails before you enter the classroom. There are far to many Smart Alec unkempt arrogant young teachers around.

The main goal for a middle school or university teacher should be to provide light relief and a once-weekly break for students, away from the discipline required from their Chinese teachers. No real teaching required here either. Most English university teachers are old, some nearly incontinent; so, more respect must be shown; inspecting their living areas would be completely out of order.
