Abstract: Before Wei and Jin Dynasties, Qin had no close relationship with literature. As Wei and Jin Dynasties began, the description of Qin appeared in large number.The reasons are the followings: in the literati consciousness era, men of letters’ concern on their destinies resulted in a strengthened relationship of Qin and their works; in the turbulent political situation, the desolating sound of Qin happened to resonate with sadness in literati’s mind; with the rise of metaphysics, the deep and natural sound of Qin provided a way to the profound theory; being a musical instrument favored by previous Confucian sages, Qin appeared to be a symbol of literati’s hopes and ambitions.The description of Qin in literature, on the one hand, enriches the literature in the Wei and Jin Dynasties, deepens the description of portrayal theme and promotes the development of poetry; on the other hand, it brings a profound significance to Qin literature,makes Qin a spiritual symbol of Chinese literature and literati, broadens the domain of Chinese traditional poetry, makes a contribution to the development of Tang poetry and Song poetry, and increases the value of Chinese traditional poetry

Key words: Wei and Jin Dynasties literature, Qin, literary history
