Abstract: The word “wuse” originally referred to color of sky, shape, sound and color. With the introduction of Buddhism into China, like the transformation of many other concepts deeply influenced by it, the wuse’s original meanings had changed to the mutual fusion between objective external environment and people’s internal feelings, that is, the perceptual knowledge of the objective world, or a kind of state. And the poems concerning the word wuse are listed in a catalog in A Collection of Literary Works, which has shown the new meanings of the word as well as the aesthetics of literati of Jin and Song Dynasties. This stood for the change from poetry of Han Dynasty which stressed the grandeur and modification to the one of Six Dynasties which highlighted the feeling expression.
