Valery's poems are the channel between classicism, symbolism and surrealism. His poems inherited the formal beauty and phonological beauty of classical poetry. In writing skills, he used a lot of symbolic techniques and images, while in the ideological level, he paid attention to inner experience and deep excavation of the subconscious. At the same time, his poetry always pursues the ultimate philosophy, which has become an important feature of his poetry. Valery is the most important founder who introduced French poetry into modernization. He put forward the theory of "pure poetry", advocated "absolute poetry" excluding all non-poetic factors, explored the form of absolute language, explored the tense, harmonious and broken relationship between words, and explored the logical and illogical relationship between images and inner. He believes that poetry is "the magic of language" and "the limit of ideal", obscure poetry is "the confusion of interest", poetry is a dual art of creation and reading difficulties, and the art of poetry is the art completed by both the author and the reader. The most interesting thing is that he said that poetry is music score, "readers should play it with their own hearts and brains." His poetic theory has a far-reaching influence than his poetry.
