Han Meng Poetry School is a school of poetry creation in the middle Tang Dynasty, with Han Yu as its leader, including Meng Jiao, Li He, Lu Tong, Ma Yi and Liu Che. They advocate "injustice is the sound", they express their anger through bitter songs, and they learn from each other to sing their own abnormal aesthetic tastes, such as "ugliness is beauty", shocking the grotesque for beauty, withering for beauty and gorgeous for beauty. It shows the creative tendency of attaching importance to subjective psychology, pursuing adventure and strangeness. Poetry forms a strange and dangerous style. In art, they strive to avoid vulgarity and be unconventional, and strive to correct the weakness and delicacy of Dali's poetic style. This new pursuit and change of poetry actively promoted the development of the artistic realm of poetry after the prosperous Tang Dynasty.
