What is the most demanding class or school rule you have ever encountered? Tell me about it.

Don't go out to eat in the afternoon. Well, a wall 4 meters high is not difficult for me. No cell phone. I will stop talking until I am found. I must wear a school uniform. I often go in and out from the high wall in the east, and I am not afraid to check at the door. Don't sleep in class, don't be distracted, but we can basically sit and sleep, so ignore it. Don't fall in love, my dad didn't even say anything about school management!
