Under what background was the poem Green written?

Background: In February, 1979, a delegation of national poets led by Ai Qing visited Guangzhou, Haikou, Sanya, Zhanjiang, Shanghai and other places with him. He talked about poetry with others, visited together, picked up shells at the ends of the earth, told jokes in long-distance buses, and wrote his Bonsai, Green, Tianya Haijiao, Seawater and Tears.

Wait, it is written in this period that green is the natural color, hope, comfort and happiness! . Mr. Ai Qing's famous poem "Green" describes the swaying of green, the beauty and illusion of green, the green moving with the wind and even the green life. Green "really has eternal charm."
