Poetry uses a bird's attachment to the land as a metaphor to express the poet's feelings.

The poet assumes that "I" is the image of a bird, and this "bird" is a bird with a hoarse throat, which makes the reader immediately infected by the poet's sense of hardship. This sense of hardship comes from a broad and deep love for the troubled motherland. In this tone, the poem further describes the objects that birds sing: land, river, wind and dawn. Judging from the modifiers in front of the four singing objects, they are all images of long-term suffering from wind and rain, grief and indignation, and struggling hard, which is in line with the spirit of the birds dedicated to the land below and strengthens the theme of "loving the land" and "loving the motherland" that the poet wants to express.
