What are the characteristics of the image of Tu in the twenty-four poems in the late Tang Dynasty?

Twenty-four Poems is a literary criticism work, and it is also a critical literary work itself-a group of beautiful four-character poems, which is quite fascinating by comparing different poetic styles with various images and establishes a special genre in poetry criticism.

Twenty-four Poems has a far-reaching influence in the history of China literature, and it has been included in various books in past dynasties. At the same time, two schools in the history of modern literature in China, which flaunt "spirit" and "verve", are both looking for their own theoretical basis. Modern scholars study the history of China's literary criticism and China's aesthetics, and regard Twenty-four Poems as a model of artistic conception interpretation.
