The loudspeaker in the classroom of the first middle school is usually only used to play eye exercises and to make urgent schoolwide announcements.
As most students had just arrived at school, the loudspeaker suddenly blared an urgent notice, and the content of this notice made many classmates jump.
"What? The vice mayor and the director of the education bureau are coming to inspect the school? What's the big occasion today?"
"I'm done for! I'm on duty today, I'd better check the floor again for any dirt…"
"Leaders are inspecting again, can't they let us study in peace?"
...
Any student could deeply relate to this feeling; whenever leaders came to inspect the school, school leaders and teachers would act as if they were going into battle, urging students to tidy up the classroom and personal hygiene. They also demanded full attention during class, forbidding any slacking or sleeping, which was many times stricter than usual.
