This period was the prosperous time of the Tang Dynasty, and the "Kaiyuan Prosperity" appeared, which prepared the necessary material conditions for the development of poetry. The unification of the country and the cultural exchanges between the North and the South and between China and foreign countries also provide a profound cultural foundation. Enlightened and compatible political and cultural policies and "selecting scholars by poetry" in the imperial examination not only made the literati's thoughts open and active, but also directly stimulated the rapid development of poetry creation. This period is the "golden age of poetry creation", characterized by the emergence of a large number of outstanding poets and poems, which can be described as the emergence of famous artists and various schools, pushing the development of Tang poetry to the peak of prosperity. Famous poets at that time included Li Bai, Du Fu, Wang Wei, Meng Haoran, Gao Shi and Cen Can. Li Bai's representative works include "The Early Development of Baidicheng" and "Difficult Road to Shu". Du Fu's representative works include Three Officials and Three Farewells.
