From Han Fu, Tang poetry, Song poetry, Ming and Qing novels and other mainstream forms of expression, we can see that the development trend of ancient Chinese literature is pluralistic and individual. In the Han Fu period, the main forms of literary expression were lyric poetry and Fu. Fu was a kind of verse that used flowery words and a lot of symbolism to express the author's feelings and thoughts. In the Tang Dynasty, the main forms of literary expression were poetry and Ci. Poetry was mainly lyrical and describing, while Ci was a literary form based on music, mainly used to express palace life and folk tales. In the Song Ci period, the main forms of literary expression were Ci and prose. Ci was a literary form based on music, mainly used to express love, landscape, and war. Prose, on the other hand, was a form of writing that focused on discussion and description. In the Ming and Qing Dynasties, the main forms of literary expression were novels and essays.

However, in Tang poetry, the Chinese form paid more attention to expressing personal feelings and life, mainly to express the poet's lofty aspirations and love for life. In Song Ci, the literary form was more focused on expressing the philosophy of nature and life, mainly to express the poet's perception and thinking about nature and life.

In ancient China, poetry and Ci were one of the main forms of literary expression. These forms of literature reached their peak in the Tang Dynasty and then gradually declined. In the Song Dynasty, Sanqu became popular. It was a literary form that mainly expressed itself through singing. The novel originated in the Tang Dynasty, and with the continuous development and change of narrative methods, it gradually became the mainstream form of ancient literature. The transformation and integration between these art forms reflected the changes and progress of ancient society.
