Appreciation of Du Fu's Poem Nine Days: (1) What are the functions of the mysterious ape and the white goose mentioned in the necklaces? (2) Combining with couplets, briefly analyze the performance of this poem. (1) "Mysterious Ape"-At dusk in a foreign land, the black ape cries mournfully, and the poet is wandering in a foreign land, homesick, and it is inevitable to cry. "White Goose"-When the white geese come to the south on autumn nights in first frost, it is easier to arouse the poet's homesickness. Comparing the phenology of his hometown, he naturally revealed the secret of the poet's heart: homesickness is sultry!

(2) The tail couplet ends with homesickness for the festive season, showing pity for younger brothers and sisters, and pinning a sense of wandering and desolation. The last sentence was remembered by the wild goose. The next sentence lamented that he suffered from war, aging and illness. While cursing that "fighting" happened one after another like forcing people to die, the poet regretted that the years kept urging people to die and vented more dissatisfaction with "fighting", the tragic root of life. This is a direct expression of the poet's thoughts and feelings of worrying about the country and the people when he is hurt.
