Su Shi’s advocacy and pursuit of the “quick”(kuai) aesthetic is a phenomenon that should not be ignored in the history of poetry. By appreciating the cheerful poems, imitating the “quick” poetry by literati of previous generations, and promoting the writing of such poetry, he was an early advocate who proposed and perfected the theory of “quick” poetry. In his writings, he combined cheerful and joyful feelings with writings uninterrupted by measuring and weighing the phrases, and tried to construct a “quick” aesthetic realm of poetry. Meanwhile, he injected into this realm new elements of humor and vigor, which established a type of poetic aesthetics in theory and practice. This poetic aesthetics was rooted in Su Shi’s personality, intelligence and life experience, and was a process of transformation and sublimation from psychological pleasure to aesthetic pleasure.
