Sun and land are the two concepts that can best summarize the characteristics of Ai Qing's poems. Poets' eager pursuit of light, ideals and a better life is often expressed through the image of the sun. Ai Qing seems to be a Kuafu, pursuing sunshine, light and ideals until his death. On the other hand, the land connected with the poet's blood is also his lifelong attachment. He once said: "This infinitely vast country and infinitely rich rural life-old or new-need its important space in new poetry." ("Poetry dedicated to the countryside? Ai Qing's concern for land is his love for farmers, nationalities and the motherland. I love this land, written in 1938 after the outbreak of the Anti-Japanese War, which is the representative work of Ai Qing's unique land complex. At the critical moment of the country's decline and national peril, Ai Qing extended a childlike innocence to the motherland, expressed his patriotic feelings, ups and downs, and pushed forward layer by layer.
