The first four sentences of this poem describe the miserable and dilapidated scene of Chang 'an in spring, with ups and downs; In the last four sentences, the poet's feelings of caring for relatives and state affairs are full of bitterness and indignation. This poem is well-proportioned, with "where the petals have spilled like tears" as the first couplet to lament the defeat of the country, "and the lonely bird has mourned" as the first couplet to worry about homesickness, while the last couplet emphasizes that the worry is deep and white, and the confrontation is delicate and the voice is tragic, which shows the poet's patriotic feelings.
