The so-called "weather in the prosperous Tang Dynasty" focuses on the overall impression given by poems in the prosperous Tang Dynasty. Poetry is rich in content, diverse in subject matter, full of emotion, high in tone, perfect in form, thorough in genre, clear in style, pure in technique, beautiful in language and harmonious in melody. Poetry is full of enterprising, positive and uplifting atmosphere of the times, echoing the youthful melody of enthusiasm, optimism and cheerfulness, which together become the characteristics that distinguish poetry in the prosperous Tang Dynasty from poetry in other periods. Look at the songs of poets in the prosperous Tang Dynasty: A Gift from Dongting Lake by Meng Haoran, Xuanzhou Building by Li Bai, all of which are "Climbing high and looking far and embracing the bright moon", and "Looking high, Wan Ren is low" in Du Fu's Searching for the Moon and Mochow in Gao Shi's Don't Move Big.
The prosperous Tang Dynasty can be divided into two periods. In the early stage, the weather in the prosperous Tang Dynasty mainly showed enthusiasm for participating in social politics, high self-confidence and self-esteem; In the late Tang Dynasty, the meteorology mainly showed keen insight, daring to expose social contradictions, a sense of responsibility for the country and anxiety about the coming social crisis. For example, Li Bai exposed political corruption in Answer to the King on Twelve Cold Nights; For example, on the eve of the Anshi Rebellion, Du Fu exposed such a sharp problem as "the wine in Zhumen stinks and the bones on the road freeze to death". Nevertheless, the poet is full of confidence and responsibility for society.
It can be said that the prosperous Tang Dynasty is the heyday of the development of Tang poetry, and the romantic poetic style full of vigorous spirit is the mainstream of poetry in this period. At this time, a large number of poets, represented by Li Bai, Du Fu, Wang Wei, Meng Haoran, Gao Shi and Cen Can, emerged, which jointly opened a magnificent golden age of poetry.
