Modern Chinese Song poem is to inherit and develop National Song Poetry Tradition and form the stylistic category of cross‐media "spread poetry". It has always been present in the evolution of the concept of the Republic of China from silent to sound film, and "sound" is an important quality of film art. It not only visibly constructs the self‐conscious history of the film from the silent to the sound in the Republic of China, but also potentially supports the history of cross‐media interpenetration between the traditional modern construction of poetry in the rhetorical dimension and the film of the Republic of China. There is also a "circle structure" between the criticism of modern Song poem and the film of the Republic of China, that is, Song poem are based on the modern construction of "collected remarks on poetry", such as "poetry traces emotions" and "entering the spirit", "poetry is that by which one carries the way" and "poetic technique", and coexist with the state structure of the film aesthetics of the Republic of China. with its nationalized ontology expression, it continues the "re‐nationalization" of the Republic of China movies.
