The sky against the earth, the rain against the wind, and the continent against the sky came from the Tang Dynasty poet Du Fu's "Ascending": Heaven versus earth, rain versus wind, continent versus sky. The high mountain looks up and stops the shadow's movement. Even if I can't really look forward to it. Among them,"Heaven versus Earth, Rain versus Wind" was one of the couplets, and "Continent versus Sky" was the second half of the entire couplet.
