What is the development of poetry in Han Dynasty?

Poetry in the Han Dynasty, China's poetry creation lasted about 400 years from the early years of the Western Han Dynasty to the late years of the Eastern Han Dynasty. Including the creation of literati and folk songs, and the literati's five-character poems achieved the highest results in Yuefu in the late Han Dynasty and the Eastern Han Dynasty. 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, that is, "ancient poems", from four-character poems to five-character poems, from Sao poems to seven-character poems, and from narrative poems to lyric poems. During the period of Emperor Wu of the Han Dynasty, the Yuefu official office was formally established, with Li Yannian, who was proficient in music, as the coordinator, responsible for making music scores and training musicians, and collecting folk songs for singing 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. 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. For example, encounter, gynecological diseases and East Gate. Some poems reflect the sufferings and disasters brought by war and corvee to the people, such as the Tenth Five-Year Conscription, Fighting in the South and Fighting in the North, Cave Dwelling in the Great Wall of Ma Yin, and Ancient Songs. Some poems reflect the love of young men and women and the pain and sadness of abandoning their wives, such as Evil, Thinking, Pulling Grass on the Mountain, Ballad of Bald Head, Mourning, Peacock Flying Southeast, etc. There are also some poems that reflect the misfortunes brought about by social unrest, such as dead fish crying across the river, martial arts and so on. In terms of art, most of the folk songs in Han Yuefu are narrative, with strong stories and vivid characters, such as A Journey to the Orphan, Mulberry in Shang Mo and Peacock Flying Southeast. The language is concise, and there is nothing to carve, such as Jiangnan; The sentence pattern is flexible and diverse, and its greatest contribution is to create and complete the form of five-character poems, which not only affects the creation of five-character poems by scholars in the Eastern Han Dynasty, but also directly lays the foundation for the prosperity of Jian 'an poems. Compared with Yuefu folk songs in Han Dynasty, few scholars in Han Dynasty wrote poems. Scholars' poems in the Western Han Dynasty mainly include Chu Ci, represented by Liu Bang's Songs of the Wind, and traditional and elegant four-character poems, represented by Wei Meng's Poems of Irony. It was not until the Eastern Han Dynasty, under the influence of Yuefu folk songs in the Han Dynasty, that literati's five-character poems began to appear. Ban Gu's Ode to History is the first five-character poem written by a scholar. Since then, literati's five-character poems have sprung up like mushrooms after rain, such as Zhang Heng's Homophony Song, Qin Jia's Poem for a Daughter, and Zhao Yi's Poem of Being Sick and Sleeping in the World. Among them, the anonymous Nineteen Ancient Poems is the highest achievement of literati's five-character poems in Han Dynasty. The authors of Nineteen Ancient Poems are mostly frustrated literati, and most of the poems express their feelings of sadness, sadness and impermanence in life, which has reached a quite mature stage in art, so it has been widely circulated among the people and become a model of five-character poems of early literati in the history of China literature. Liu Xie praised it as the "crown of five words" in Shi Ming with Wen Xin Diao Long, and gave a high evaluation. Han Yuefu folk songs are mainly preserved in Guo Maoqian's The Book of Songs and Yuefu poems in the Song Dynasty. Scholars' poems in Han Dynasty are mainly found in Historical Records, Hanshu and Houhanshu, as well as Selected Works of Children in Southern Dynasties and Yutai New Poems by Chen in Southern Dynasties. Today, Qin Kun has compiled poems from the pre-Qin, Han, Wei, Jin and Southern and Northern Dynasties.
