So this is most schools in mainland China. I'm surprised you are detailing all these moments and micromoments and discussing them as terrible moments because you said you've taught in Northern China before?

So really all of these things are really standard for China and quite seriously you were given far more than maybe 90% of ESL teachers in China would ever be given in terms of explanations or your complaints etc.

but seriously the thing is you described a typical example. That almost everyone ever teaching in China will always deal with daily all the time. Which is not a good thing at all.
