A poem written by the swallow in Princess Zhu Huan.

There are walls all around.

Look up at the mouse,

Look down at the cockroach.

A dog is standing in front of the door.

Eat meat and bones.

Here comes another dog,

Both of them broke their heads.

Smiling yesterday,

Today is very bitter.

Crying and laughing,

Always dying.

Since I came to Shufangzhai,

Palace doors and prison doors are inseparable.

Despite the Qian Qian era,

Sooner or later, my head will fall off

There is also a poem in the first part. I don't remember the first three sentences, but I remember the last sentence: pick up a pen and call my parents.
