What kind of writing is used to write a poem and song?

Hello, landlord

Landlord, I have a poem:

Books are like an extraordinary warship.

Take us to the wide world.

Books are like a magical horse.

Show us the true meaning of the world.

Even if you're broke,

No fence can stop it.

You are wandering in the kingdom of books.

What a smooth journey!

But it has bullets.

All the beauty of the human soul!
