(2) Political factors/monarch advocacy: Several powerful monarchs in the Tang Dynasty not only loved music, but also advocated it. Gao Zong and Wu Hou, who are good at music, often make new words and organize them into Yuefu. When I arrived in Xuanzong, the wind was even stronger. He is a poet, musician and actor. He loves literature and art and is arty, which has a certain stimulating effect on the development of literature and art. In addition, he took poetry as a scholar in the Tang Dynasty, so he became a shortcut for literati to obtain official positions and played an important role in strengthening the training of poetry skills and popularizing poetry.
(3) The evolution of poetic style/the development of literature itself: from the Book of Songs and Songs of Chu in the pre-Qin Dynasty, nineteen Yuefu folk songs and ancient poems in the Han Dynasty, to the poetry creation in Jian 'an, Zhengshi and Jin Dynasties, and even the proposal and application of the theory of temperament in the Southern and Northern Dynasties, they have accumulated rich creative experience for Tang poetry. Seven-character ancient poems and rhyming quatrains, a new poetic style, began to take shape in the Six Dynasties, and its form and rhythm began to take shape. The social life in the Tang Dynasty became more and more complicated, and the poet's thoughts and feelings were rich. In poetry creation, new content needs new forms, and poets in the Tang Dynasty used new forms to express their feelings, which made these new-style poems mature in form, rhythm and rhetoric.
(4) The activity of ideology and culture/the influence of other arts on the development of poetry: The development of Tang poetry is obviously influenced by other arts. Music, sculpture, dance and painting in the Tang Dynasty absorbed foreign influences on the basis of China tradition, which had a positive impact on the content and style of poetry. For example, Wang Wei's landscape poems are known as "paintings in poems" and are obviously influenced by landscape paintings. As for Li Qi's, Cen Can's and Du Fu's poems about music, dance and painting, we can see that writers are brave enough to accept new things.
