The weakness of the dynasty made the poets in the late Tang Dynasty lose their lofty sentiments in the past, while Du Mu's poems by Li Shangyin have revealed a strong sentimental atmosphere when they are worried about the country and the people and lament the life experience. Their debauchery poems also reflect spiritual emptiness.
Since the establishment of Li Yuan in Tang Dynasty, it has entered a period of high prosperity. The Tang Dynasty was one of the most powerful countries in the world at that time. In the middle and early Tang Dynasty, the government was clean and talented, and the country developed rapidly on the normal track. The Tang government opened to the outside world and the Silk Road appeared.
There were few ideological imprisonments and literary inquisitions in the Tang Dynasty, which created an ideological environment for the prosperity and development of literature. The Tang government used Confucianism, Buddhism and Taoism, and all kinds of ideas were inclusive. The establishment of schools at all levels, the imperial examination system for selecting poets, and the emperor's love and admiration for literature all made the literature of the Tang Dynasty unprecedentedly prosperous.
