"Why do I often have tears in my eyes? Because I love this land deeply ",these two poems are true and simple, but they come from the poet's heart, from the depths of national life, and have immortal artistic vitality. In his famous work Dayan River-My Nanny, Dayan River is the embodiment of China people and farmers, which not only shows Ai Qing's sympathy and love for the working people, but also shows his concern and exploration for the fate of the working people.
