First of all, judging from the style of Tang poetry and Song poetry, Tang poetry is more bold and unrestrained, while Song poetry is more carefree, which is inseparable from the social situation at that time. In the heyday of Tang Dynasty, Li was an unprecedented romantic poet, and his poems were like wild and unconstrained style, which was unimaginable to ordinary people. A little fairy spirit is enough for ordinary people to look up, and his poems reflect his free and unrestrained character, so they are called. Su Shi was born in the Song Dynasty. In the Song Dynasty, all kinds of literary forms developed, and the form of poetry could not surpass that of Tang poetry. Thus, it found a new way for the development of Song Ci and formed a unique artistic style. Su Dongpo was the peak of Song Ci.
As far as their most outstanding literature is concerned, Li Bai and Su Shi are undoubtedly the top literati in the history of the Chinese nation.
