Realism, as a kind of creation technique, existed at the beginning of the birth of literature. By the 19th century, European literacy theorists introduced realism from painting to literature, during which the intelligentsia hope to integrate literature activities into the whole society. The holistic thinking mode which regards the society as observation fields set the stage for realism ideology to present a trend of boundlessness in literature field. With the May Fourth New Culture Movement, Chinese literature creators inherited the Chinese traditional pragmatic spirit, as well as the intellectuals’sentiments of conveying philosophy in Literature. In this idea of realism, they created a variety of literatures with respective characteristics: for instance, Lu Xun employed his moral introspection to raise the awareness of the public; while for Mao Dun, his political dream was embodied in his literature. They applied different ways to reach the same purpose, which represented a nation’s nationalism. Of course，this kind of limited literature creation with personal characteristics has enriched the connotation and presentation of realism, which is consistent with the characteristics of activeness and boundlessness of realism.
