How to appreciate the theme of poetry?

Hope

Friends of dreams

Fantasy sisters

used to be their own shadows

but they always walk in front of you

as invisible as light

as unstable as wind

There is always a distance between her and you

like birds outside the window

like floating clouds in the sky < She drives you away

she will accompany you forever

until you stop breathing

Ai Qing, starting from his love for rural working people and approaching their demands, has been presenting his truest poetry to them for more than ten years.
