Language: What does the rain mean in Wen Tianxiang's Zero Crossing and Ding Yang?

The whole sentence is: the mountains and rivers are broken and the wind is floating, and life experiences are ups and downs. The author uses "catkins floating in the wind" as a metaphor that the national situation is as critical as catkins in the wind, and uses "the rain is flat" as a metaphor for the bleak state of his home. Duckweed is a symbol of loneliness, and the poet added the word "rain" to the word "ping", making it even more miserable. "Flocculation in the Wind" and "Rain Beats Duckweed" together write the bleak situation of the country's ruin and death, and compare the broken great mountains and rivers of the motherland with their own duckweed-like floating life. In these two poems, the poet used a bleak natural scene to describe the decline of state affairs and deeply expressed his grief. Being a lonely minister, like a rootless duckweed floating on the water, is already miserable without caring. The antithesis of this couplet is neat, the metaphor is appropriate, the image is vivid, and the feelings are strong, which makes people sad to read!
