"The floating clouds travel all day long, and the wandering boy will not arrive for a long time." It is a common practice among poets to see the floating clouds and miss the wandering boy. Li Bai also has a poem "The floating clouds wander around, and the setting sun brings the affection of an old friend" ("Farewell to a Friend") . The floating clouds in the sky come and go all day long, but old friends from far away are never seen for a long time. Fortunately, Li Bai was deeply in love and his soul came to visit frequently, so that the poet could talk and relieve his sorrow.
