(1) The two words "yun" and "nong" in the first couplet use personification to make "rain" and "wind" fully expressive and full of interest; "congcong" and "leaf" The two words "leaf" are overlapping words, which adds to the musicality, is catchy, and has an endless aftertaste. (2) The lyrical style (technique) of the entire poem is joy, scenery and sadness. The first three sentences describe the scenery, which is extremely bright and joyful, and the atmosphere is broad and capable, without the bleakness of autumn in the north. The two words "kan" in the last sentence constitute a contrast in mood. Although the foreign country is beautiful, it is only a picture and cannot comfort the pain of homesickness. The more homesick the author becomes. There is no explicit statement about homesickness in the poem, but the euphemistic emotion in the song makes the whole poem fresh and natural, and full of realms.
