What did Sun Ningbo, a poet in spring, see?

I saw a young man in a white sweater. He walked over slowly, as if waving to me personally. In this poem, Ai Qing describes the scene and feelings of spring, and expresses her admiration for the beauty of nature and awe of life in poetic and profound language. Among them, "Ningbo Sun" means that the sun rises from Ningbo where Ai Qing is located and shines all over the city. The young man in a white sweater described in the poem came over and waved to Ai Qing, showing the author's yearning and pursuit for life and love.
