1. First of all, the poetry and song criticism in the Tang Dynasty formed a universal philosophical thought within the framework of the overall historical tradition, emphasizing the unity of poetry culture and providing a systematic and comprehensive theoretical guidance for poetry creation. Under the guidance of this theory, the authors of Tang poetry analyzed the artistic practice of poetry, remolded the concept and method of artistic creation in Tang dynasty by using creative methods, made the artistic conception, emotion and expression of poetry more refined and elegant, and influenced famous poets such as Wang Wei, Li Bai and Bai Juyi with philosophical thoughts, thus producing many classic works, adding rich classical culture to later poets and becoming the representative works of Tang poetry.
2. Secondly, the influence of Tang poetry criticism on the creation of Tang poetry is also reflected in the poetic meter. The Tang Dynasty opened up the creative form of poetic meter, unified the standard of poetic meter, and made a systematic exploration of chords, which better reflected the richness of Tang poetry. For example, in Tang poetry, quatrains pursue rhyming antithesis and take rhythm as the main theme; In addition, in the form of poetry, it also integrates other forms of poetry, bringing together hundreds of poems, so that various forms of poetry such as three sentences and four sentences can be more widely expressed in literature.
3. In addition, the influence of poetry criticism in Tang Dynasty is also reflected in the diversity of poetry. Both thinkers and realistic critics in the history of poetry emphasize the abstraction and richness of Tang poetry, as well as the principles of poetic skills and literal expression in the process of creation. In addition, the famous poets in the Tang Dynasty also made the poetic images more thorough, direct and realistic according to the philosophical theory at that time, combined with the constant thinking of practical problems and the simple description of life experiences.
