What is an uncivilized phenomenon on campus and what is an uncivilized behavior on campus?

1, large does not flush. When you want to go to the toilet, open the door and a piece of shit is waiting for you there.

2, smoking in the corridor, sometimes the smell of smoke can enter the classroom.

3, smoking in the toilet, there is no smell and smoke in the toilet.

In the classroom, the mobile phone doesn't vibrate or mute, and maybe it will make a loud noise.

Make a phone call in the classroom, always make a phone call in the classroom, or make a phone call when walking outside.

6. Listening to music with headphones in the classroom, you can hear the sound every few rows. I don't know whether to turn down the sound or change the headphones with better sound insulation.

7. Don't pay attention to your voice when you speak in the classroom.
