In contrast, Tang poetry is mainly emotional, cheerful and healthy, and wins with the environment; Song poetry is based on reason, profound and tortuous, and wins with meaning. Poets in the early Song Dynasty, such as Yang Yi and Qian, studied Li Shangyin, whose name was Quincy style. Wang Yucheng, Mei, et al. Opposing the disadvantages of Quincy-style only talking about temperament and rhetoric without social content laid the foundation for the healthy development of Song poetry. Ouyang Xiu advocated the poetry innovation movement and restored the tradition of paying attention to reality. The tendency of paying attention to spirit and being good at thinking in Song poetry is more and more obvious. Su Huang was the most influential poet in the Northern Song Dynasty. Su Shi is a writer with the most comprehensive literary and artistic achievements in the Song Dynasty. His poems are lyrical and free, which develops the tendency of argumentative and prosaic culture in Song Dynasty. Huang Tingjian, the founder of Jiangxi Poetry School, paid attention to the reference and creation of poetic language, and advocated "turning iron into gold", "robbing the fetus for bones" and "no words can be found anywhere". His poems are based on Du Fu, thin and hard, and innovative. There are other poets in Jiangxi, such as Chen and others. The outstanding representatives of poets in the Southern Song Dynasty are the "Four Great Poets of Zhongxing" (Lu You, You Mao, Yang Wanli and Fan Chengda), all of whom came from Jiangxi Poetry School, and finally they all became their own. Lu You was a great patriotic poet in Song Dynasty, with nearly 10,000 poems, which sang the strongest voice of the times. By the end of the Song Dynasty, the patriotic poems of Wen Tianxiang, Wang Yuanliang and others added the last glory to the poetry circle of the Song Dynasty.
