The Western Han Dynasty set up Yuefu, which was in charge of court and court music. Poems collected and created by Yuefu are called Yuefu. A considerable number of Yuefu poems are collected from the people, which are easy to understand, reflect reality and can be appreciated. Later, scholars also copied Yuefu poems. By the Tang Dynasty, Yuefu poems before the Southern and Northern Dynasties were collectively called Ancient Yuefu. The so-called new Yuefu is relative to the ancient Yuefu. This concept was first put forward by Bai Juyi. He has compiled more than 50 poems, such as Beauty is Better than Happiness and Setting a Topic for Something, into New Yuefu. Pi Rixiu, Nie and Du Xunhe, poets in the late Tang Dynasty, inherited the spirit of the new Yuefu. Pi Rixiu's ten poems and three shameful poems, Nie's Journey to the Childe, Du Xunhe's Widow in the Mountain and Houhui Village Rebellion, profoundly exposed the cruelty and decay of the rulers in the late Tang Dynasty and the social reality before and after the peasant war in the late Tang Dynasty. Baidu Encyclopedia-Han Yuefu Folk Songs The artistic features of Han Yuefu folk songs are shown in 1. Characters' personalities are expressed through their words and actions, some in the form of dialogues and some in monologues. Pay attention to the description of characters' movements and details to make them more direct and real. 2. The language is simple, natural and full of emotion. The language of Han Yuefu folk songs is generally colloquial, but it is also full of feelings, full of people's love and hate. Even narrative poetry is a combination of narrative and lyric, so it has a strong appeal. On the one hand, the folk songs of Han Yuefu are mostly about the people themselves, and the author of the poem is often the hero in the poem; On the other hand, because the author and the characters he describes have the same fate and life experience, narrative and lyricism naturally blend together to achieve "shallow and profound". ? 3. Freedom and diversity of forms. The folk songs of Han Yuefu have no fixed rules and syntax, and the length is arbitrary, and the forms are scattered and diverse, which is undoubtedly very helpful for expressing complex ideological content. 4. Romantic color Most of the folk songs of Han Yuefu are accurate descriptions of realism, but some works are romanticized to varying degrees and use romantic expressions. ? The expanded data shows that the influence of the folk songs of HanYueFu is 1, which shows its realistic spirit of "feeling sad and happy, starting from something". This spirit, like a red line, runs through the history of poetry and songs from Jian 'an to Tang Dynasty, forming a realistic tradition with Yuefu as the system. The relationship between the two is so clear that we can make the following statement with lines: "Starting from things" (folk songs of Han Yuefu)-"Writing current events by things" (Jian 'an Caocao Ancient Yuefu)-"Being famous for things, there is nothing to rely on"-"Poems and songs are combined into things" (White Pony 2). It is also reflected in the creation of new poetic forms. The main forms of folk songs in Han Yuefu are miscellaneous words and five words. Since Jian 'an, the influence of miscellaneous language has become increasingly significant. Li Bai's songs, such as Shu Dao is difficult, the city is difficult to fight, etc. It is even more spectacular, all from the Han Yuefu. The influence of five-character style is earlier and greater than that of miscellaneous words. According to the existing literature, it is certain that literati began to write five-character poems from the early years of the Eastern Han Dynasty, such as Ban Gu's "Ode to Historical Poems". By the end of the Han dynasty, there was a situation of "five words surging" Since then, it has been an important traditional form in the history of China's poetry to take four words from The Book of Songs in one to replace the poetic style of Chu Ci. 3. In terms of artistic techniques, especially in the writing skills of narrative poems, the influence of folk songs in Han Yuefu is also very significant. Such as the use of dialogue or monologue, psychological description and detailed description of characters, simple and vivid language, etc. It has become a learning model for all poets who reflect reality in later generations. Yuefu folk songs in Han Dynasty reflect reality, and the criticism of reality is usually through an objective and concrete description of reality, but sometimes the purpose of writing is revealed at the end of the poem, which is also enlightening for Bai Juyi's "dying to show his will". To sum up, Han Yuefu folk songs are an emotional liberation in the history of China's poetry. Han Shuzhi refers to this feature when he says that the folk songs of Han Yuefu are works of "mixed sadness and joy". This is also very important for the development of poetry. Poets with strong feelings in later generations are often inspired by this. Li Bai's Battle of the City is an imitation of the folk songs of Han Yuefu.
