What are the characteristics of poetry in Han Dynasty?

1. Poetry in the Han Dynasty developed on the basis of The Book of Songs, Songs of the South and the folk songs of Qin and Han Dynasties, and generally experienced the development process from folk songs to literati's creation, from Yuefu songs to literati's poems, from four-character poems to five-character poems, from Sao style to seven-character poems, and from narrative poems to lyric poems.

2. During the period of Emperor Wu of the Han Dynasty, Yuefu official office was formally established, with Li Yannian, who was proficient in music, as the captain of the association, responsible for making music scores and training musicians, and collecting folk songs on a large scale. With the establishment of Yuefu official office, the folk songs of the Han Dynasty were preserved in large quantities, and when the literati poetry circle of the Han Dynasty was particularly neglected, they shone brilliantly, forming the third important development stage in the history of China's poetry after The Book of Songs and Songs of the South.

3. Han Yuefu folk songs have a wide range of themes and rich contents. Some of these poems exposed the extravagance and cruelty of bureaucrats and nobles, reflected the pain of working people's lives, showed the sharp class opposition in Han society, and conveyed the angry and rebellious voice of the oppressed people.
