This paper discusses the Hu Shih’s the concept of literature in National Language focusing on the influence of English literature in two main aspects. First, Hu was able to taste the essence of Western literature, especially English literature through Lin’s Translation Novels, and Hu’s interest in English literature deepened after studying in the United States. In short, Western literature, especially English literature, not only broadened Hu’s perspective on Western art and culture, but also suggested a certain direction in establishing the Literature in National Language after return to China. Second, Hu paid attention to the case of Britain among aspects of the National Language movement in medieval Europe. This historical background of medieval English served as an important argument to support Hu's argument to establish Chinese literature through language reform. Hu needs to improve Chinese literature by focusing on the problem of language letters and further expanding the scope to the problem of literature stems from Hu’s awareness of the development and overall flow of the European literary movement. I argued that the significance of English literature in terms of providing a more important reference standard for establishing Literature in National Language literature in China. 저
