Ai Qing's "green" seems to be/green/ink bottle/upside down, green everywhere ... where to go/where to find/so many greens: dark green, light green, pink green ┅ ┅ green is black, surprisingly green; The wind is green, the rain is green, the running water is green and the sunshine is green. All/green/together, crowded together, overlapped together, quietly/crossed together. Suddenly/with a gust of wind, it seems that/the dance teacher/is conducting, and all the greens/are neatly in accordance with the beat/fluttering/together ... to divide the rhythm of poetry? In the era of The Book of Songs, the dominant form of poetry is four-character poetry.
