Later, with the continuous development of poetry style, poetry and emotion developed, and finally formed the theory of poetry based on emotion. Later, with the program of "Poetry is based on emotion, supplemented by ornateness", the poems of the Six Dynasties blindly pursued formal beauty and advocated flashy beauty, and finally became the object of criticism.
On the basis of the literary style of the Six Dynasties, the political and religious functions of poetry were once again paid attention to, and the concept of "emotional development" appeared, which not only emphasized the political and religious functions of poetry, but also emphasized the expression of personal sincere feelings.
Since then, "expressing ambition" and "fatalism" have become two indispensable pillars in China's poetic theory, and have had a far-reaching impact on later poetry creation and the development of poetic theory.
