What kind of poetic phenomenon is reflected in Far and Near?

This poem is very much like a push-pull lens in photography. It uses the transformation of subjective distance between "you", "me" and "cloud" to express the habitual fear between people and the intimate relationship between man and nature. This contrast is not without tendentiousness, which implies the poet's desire for human nature to return to nature. -Gu Cheng and this poem also talks about distance, talking about two kinds of remoteness, one is distance, but it is a soul mate. Such as between clouds and people. The other is the distance between heart and heart. Although the distance is close, the heart is far from the heart. This may also express the poet's unreachable helplessness to him.
