When was the peak of the development of Tang poetry?

The development of Tang poetry can be divided into four periods: early Tang, prosperous Tang, middle Tang and late Tang.

The early Tang Dynasty was the pioneering period of Tang poetry.

Poetry in the prosperous Tang Dynasty represents the highest achievement of Tang poetry. The two schools of poetry in the prosperous Tang Dynasty are the pastoral poetry school represented by Wang Wei and Meng Haoran and the frontier poetry school represented by Gao Shi and Cen Can. Wang Changling, William Wang, Wang Zhihuan, Li Qi, Cui Hao and other important poets of the Frontier Poetry School. Li Bai and Du Fu were two great poets in the prosperous Tang Dynasty, and their poems represented the highest achievements of Tang poetry and even China's classical poetry. Zhang, He, Zhang Xu and Bao Rong are called "Wu Sizi".

Poetry creation was at a low point in the early middle Tang Dynasty, and reappeared in the later period.

Late Tang Dynasty is the period when the setting sun of Tang poetry shines again. The overall situation of the poetry world is a strong sentimental atmosphere and a prevailing carving atmosphere. Li Shangyin and Du Mu are very famous poets in the early late Tang Dynasty, and they are called "Little Du Li". They are also the most accomplished poets in the late Tang Dynasty.
