The poet assumes "I" to be the image of a "bird", and this "bird" is a hoarse bird that has suffered a lot, making the reader immediately infected by the poet's sense of worry. This sense of urgency comes from our profound love for our motherland, which has suffered many disasters. Under this tone, the poem further develops the description of the objects the birds sing about, which are: land, river, wind, and dawn. Judging from the modifying words in front of the four singing objects, they are all images that have been hit by wind and rain for a long time, full of grief and anger, and struggling hard, which is consistent with the spirit of the birds dedicated to the land below, which strengthens the " The themes of "Love the Land" and "Love the Motherland".
