In the history of China's poetry, there are three theories: what is Tang, what is Song and what is Yuan.

Tang poetry-the highest achievement of Tang poetry, represented by Du Li.

Song Ci, the poetry of Song people, was eclipsed in the Tang Dynasty, but its poetic attainments far surpassed those of the Tang Dynasty represented by Su Dongpo and Li Qingzhao.

Yuan Qu —— As an alien rule, the cultural expression of the Yuan Dynasty was quite different from that of the previous dynasty, which gave birth to the vigorous development of Qu represented by Guan Hanqing, Bai Pu, Ma Zhiyuan and Zheng Guangzu.
