In the late Northern Song Dynasty, Huang Tingjian had a great influence on the poetic world, and gradually formed a poetic school centered on Huang Tingjian. Lv Benzhong put forward the name of "Jiangxi Poetry School" for the first time in the "Sect Map of Jiangxi Poetry Society", and regarded Huang Tingjian, Fang Hui, Du Fu, Huang Tingjian, Chen as the first three schools of Jiangxi Poetry School. The poetry theory of Jiangxi Poetry School emphasizes "replacing bones with fetuses" and "turning iron into gold", that is, inheriting the words or meanings of predecessors; Advocating thin, hard and strange poetic style; The pursuit of every word has a source. In the creative practice, the school of poetry "takes the old as the new", and the poetry styles of important writers are different, which has become the most influential school of poetry in the Song Dynasty. Its influence spread throughout the Southern Song Dynasty, and its aftermath extended to modern Tongguang poets.
