What are the artistic developments of poetry in the late Tang Dynasty?

With the decline and turmoil of the national situation, the style and features of poetry in the late Tang Dynasty also changed greatly. There are some new artistic developments in Du Mu's and Li Shangyin's poems, but they all have a strong sentimental sentiment for the country, the people and love life. Pi Rixiu, Nie and Du Xunhe wrote some poems exposing social darkness before and after the Huang Chao Uprising, which inherited the tradition of Bai Juyi's new Yuefu, but their feelings were stronger and their criticisms were sharper. From their poems, we saw the crumbling scene of the Tang Dynasty.
