Ai Qing’s poem chose the sun to symbolize light. It expresses the author's firm belief that history is unstoppable and the arrival of light is inevitable. When the Anti-Japanese War of National Liberation turned from national peril to a great historical turning point of rebirth, the poet watched the changes of the times with keen eyes and discovered "the hidden vitality of the nation, which is also the most profound power of national liberation."
In the "Sun" group of poems, a group of bright images that are opposite to many images of suffering began to appear. Such as torches, flames, horns, spring, dawn, dawn, sun, etc., Ai Qing's poetic style began to orient towards the praise of bright things, and the poet's pursuit of national liberation, democracy and freedom became the theme of poetry creation. This poem is a very typical reflection of the trend of the times of those passionate young people who loved the motherland, devoted themselves to the war, and sought liberation.
