How to divide the rhythm of poetry?

Ai Qing's "I Love This Land" divides the rhythm:

If/I were a bird, I should also/sing with a hoarse throat/.

This land/is struck by storms/, this/is always a raging river of our sorrow and indignation.

The angry wind that blows endlessly, and the extremely gentle dawn that comes from the forest.

——Then/I died, and even my feathers rotted in/the earth.

Why/are there always tears in my eyes/? Because/I/love/this land/deeply.

Literary Appreciation:

The lyrical perspective has been changed. The first stanza of the poem is imagined from a virtual perspective, that is, from the bird's perspective, to express the bird's loyalty and love for the land, which appears to be an implicit image; but the second stanza is changed to a realistic perspective, that is, from the author's own perspective. To express his "eyes often full of tears" from a different perspective, and to express his "deep" love for the land, he expressed his true feelings.

In this way, the combination and correspondence between the virtual and the real create a complete artistic space within the whole poem; the correlation and contrast between the result and the cause also constitute the internal logical structure that supports the whole poem.
