This poem was originally composed of three chapters: one chapter with four sentences, two chapters with eight sentences and three chapters with eight sentences. Zheng Xuan divided the last two chapters into two chapters, five chapters and four sentences in each chapter. Zheng Xuan's method is used now. In the first chapter, pigeons and birds are singing on the river continent, and gentlemen are good. The beauty of this chapter lies in soothing the voice of justice. Gentleman's affection dominates the whole poem. The second chapter, Jagged Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd's Shepherd. Liu and Mao Zhuan are taught as "seeking", which is not accurate, because the following "seeking" already exists. That is, from deep yearning to the realization of marriage desire. The third chapter expresses the anxiety of not being able to do so. This is the key of this paper, which can best reflect the spirit of the whole poem. Comments on Yao Jiheng's General Theory of the Book of Songs: "There are four chapters, four sentences in each chapter, and the meaning of the words is easy to understand. Today, if we put these four sentences under "seeking", "being friends" and "being happy", then the cloud above is seeking, and the cloud below is friendship and happiness, which is weak and sluggish. This ancient prose strives to be concise, and the tone is also forcibly improved, which is different from the light tone before and after. " Yao's analysis of the importance of this chapter in the whole poem is the most accurate. What needs to be added is that this chapter not only carries forward the literary spirit with complex strings, but also writes vivid and vivid images. That is, Wang Shizhen's "Yu Yang Poetry" called "three hundred poems, really like a painter's masterpiece". In Lin Yiguang's Total Interpretation of the Book of Songs, he said: "I wake up, tossing and turning, still in bed." This description of the thoughts of missing one's lover can be described as "mourning without hurting". Chapters 4 and 5 are about the happiness you get. "Friends of piano and harp. The use of words has its own weight and depth. As the saying goes, "happy but not extravagant" is written quickly and happily. The whole poem is about a man's yearning and pursuit of women, his anxiety and happiness that he can't get.
