When I was teaching high school, I had one class that was always right before dinner (eighth period). They were good enough kids, but for the last ten minutes of class they would get antsy. So I decided at the beginning of that class I would just take the clock down and put it on the teacher's desk. Problem solved. It seemed like a pretty minor thing so I didn't even think about it.

That ended up becoming a major source of gossip among the teachers, and admin, but no one talked to me directly about it, or asked me why I took down the clock (to this day, they have no clue why I did that, no one asked me, they just screamed their batshit racist theories as to why I did it at me). One day, some people from admin took me into an office and yelled at me for about an hour straight about me taking down the clock. Most of it was a mix of racist slurs and gibberish, and when I asked what was so bad about taking down the clock, they said, "No one has ever done it before."

The funny thing is, that school was always encouraging me to introduce "foreigner teaching methods" and telling me to always be as foreign and unusual as possible, and scolding me for not being foreign enough, and there were signs everywhere encouraging teachers and students to be "innovative" (创新), but one step away from the established norm was treated like a major crisis.

One time I let the students go a minute or two early, and I was told by another teacher not to do that, or I could get in trouble. However, sometimes I hear other students from other classes in the hallway a minute or two early. Sometimes I take students outside, and if it's the class before lunch, most of them disappear 10 minutes early. I haven't gotten in trouble for that though.

I just got scolded last saturday.

As you probably know, it was the weekend of the tomb Sweeping "festival". We had to teach mondays class on saturday and tuesdays class on sunday.  Only problem was, no one told the foreign teacher (I am the only one itn the school).

Anyway, they did not yell, but I was called by phone for not being in the classroom. When I pointed out that I had not been told, they said that a note was taped to my door.

I then remembered the note that was indeed taped to the door. HOWEVER, since it was in Chinese I did not read it.

Anyway, they did not believe me, so I took the note to the office on Sunday, after I finished my "tuesday" class and showed them the note.

They were very apologetic and the Dean even took me to dinner this evening. This has been my only experience.

As to yelling, I would not stand for it. When I was a new, "freshly minted" prosecutor the D.A. yelled at me once. I calmly told him not to yell. When he yelled at me louder, I got up and went to my office.  My friends STILL cannot believe that I was not fired!

I can't say I was ever yelled at.

Only by my wife, daily

Well done OP on trying to show the Chinese that there are other methods for learning and that outdated thousand year old Confucian ideals are irrelevant.

Unfortunately for you, you get ass-reamed daily and paid a pittance whilst your foreign face is bringing the cash flowing in for the University.
