What's the use of English poetry?

One of my favorite English poems:

When night falls

I stood on the steps and listened;

There are stars in the garden.

I stood in the dark.

Listen to Lu Xing's voice!

You don't walk barefoot on the grass,

My garden is full of star fragments.

Theme of the poem: The author looks at the stars under the night sky.

Why I like it: The author expresses his sincere understanding of the world through a detailed description of the stars in the night sky.

Enlightenment to me: As a kind of existence of nature, people look up at the starry sky and feel the integration of heaven and earth in the quiet night.
