From The Book of Songs to Songs of the South, what development and changes did China's poems show?

Qu Yuan is the first great poet in the history of China literature, and the appearance of Qu Yuan and his works initiated a brand-new era in the history of China's poetry ―― a new era of poetry from collective singing to individual independent creation. Qu Yuan also created a brand-new poetic style, and his works are very original. He created a brand-new literary genre-"Sao Style" on the basis of the folk songs of Chu in the south at that time. Compared with The Book of Songs, this new style of poetry has made great progress in length, syntax and expression, and greatly expanded the expressive force of poetry. It is by using this new poetic form that Qu Yuan galloped his rich imagination and poured his warm feelings into writing great and famous poems such as Li Sao, which showed the first plump and distinctive lyrical image in the history of China literature. These creations are unprecedented in the history of poetry, and have a great influence on the development of China literature.

In art, after The Book of Songs, Qu Yuan opened up another far-reaching tradition for China literature with positive romanticism, thus enriching the artistic expression of China literature. The Book of Songs and Qu Yuan's works are the first two towering peaks in the history of China literature. However, The Book of Songs has become an example for future generations to learn more with the style of folk songs and realistic techniques. Qu Yuan's works had a great influence on later generations by romantic means such as bold fantasy, imagination and exaggeration. After the appearance of Qu Yuan's works of Chu Ci, "Feng" and "Sao" became two criteria for ancient China people to evaluate poetry. As the beginning of China's positive romanticism, Qu Yuan's works are of special significance to the development of China's ancient poetry.

On the artistic expression of poetry, Qu Yuan also developed the metaphor of The Book of Songs, which contributed to the formation of the national artistic characteristics of China's poetry. Bixing technique is indeed the characteristic of many folk songs in The Book of Songs, and it was also initiated by The Book of Songs. But Qu Yuan made an important development to it. Bixing in The Book of Songs is often just a fragment of a poem, which is mostly simple. What is used to arouse harmony is still an independent object. But Qu Yuan changed and developed. First of all, it began to integrate things with me, feelings with scenery, and expanded the realm and expressive force of poetry. Therefore, Bixing in Qu Yuan's works is not only to simply compare something with something, or to get excited by touching something, but to combine some characteristics of something with people's thoughts, feelings, personality and ideals, so that things have symbolic significance and feelings have more specific attachment and sustenance. It opened up the expressions of "attaching affection to things" and "borrowing things for irony" in later generations, which had a great influence on China's ancient literature, especially poetry creation.
