Since Yan Yu's Poems on Canglang in the Southern Song Dynasty, there have been serious differences in the evaluation of Song poetry until the formation of two schools of "respecting Tang" and "worshiping Song" in the history of literature. Generally speaking, Tang poetry focuses on emotion, while Song poetry focuses on rationality. From an artistic point of view, many works of Song poetry lack vividness, beautiful music and weak appeal, which are its shortcomings. From the perspective of cultural history, Song poetry found a new way under the condition of complete rhythm and ingenious images in the prosperous Tang Dynasty, which provided an example of contemporary significance for the development of modern poetry and was the success of Song poetry.
In the history of China's poetry, Tang poetry and Song poetry, as two insurmountable peaks, shine brilliantly in the cultural field of China, and are also controversial by scholars. From the writing background of poetry to the structure of poetry, hammering words and phrases, rhetorical allusions, people love to attack.
Aside from the consideration of ideas and starting points, there are different opinions, and the debate on poetry itself is beneficial to the development of poetry itself after all. From this point of view, Mr. Zhang Yi's "The Debate between Tang Poetry and Song Poetry in the 20th Century" not only comprehensively lists other people's views, but also clearly expounds his own views, which can be described as supercilious.
