Wei and Jin literature returned to the characteristics of literature itself in a diversified situation. This is its most important feature. Its "consciousness" is not only related to its own value and status in literary history, but also to People’s objective evaluation of this period of literature and their views on the entire literary process. The importance of the "consciousness" of Wei and Jin literature is that it fully prepared for the overall prosperity of Tang Dynasty literature. Without the prosperity of Wei and Jin literature, there would be no prosperity of Tang Dynasty literature. In addition, the literature of Wei and Jin Dynasties is of great significance in the history of stylistic development. The emergence and development of many Chinese literary styles are related to this period. For example, the influence of Yongming style on rhymed poetry contributed to the emergence of rhymed poetry in the Tang Dynasty, and parallel style prose was the peak in the development history of Chinese parallel prose. At the same time, Wei and Jin literature’s thinking on the fate of literati had epoch-making significance, and it affected changes in literary concepts.
