I am urgently looking for an ancient poem that describes the classroom situation during class. There is no limit to whether it is original or quoted.

It’s already dusk in front of the classroom building

Lin Ling’s song is still melancholy

Singing to the heartbreak of Emperor Ming

Crying in the stomach< /p>

I always remember yesterday’s great things,

I don’t know why.

The hall was full of "extremely poor students",

Countless people fell on the table,

Quiet, quiet,

Listen to a "snoring"
