In the early 20th century, although the New Culture Movement took a critical view of the Confucian classics, the scholar Hu Shih used the tools of textual criticism to put the novel in an entirely different light, as a foundation for national culture. Hu and his students, Gu Jiegang and Yu Pingbo, first established that Cao Xueqin was the work's author. Taking the question of authorship seriously reflected a new respect for fiction, since the lesser forms of literature had not been traditionally ascribed to particular individuals. Hu next built on Cai Yuanpei's investigations of the printing history of the early editions to prepare reliable reading texts. The final, and in some respects most important task, was to study the vocabulary and usage of Cao's Beijing dialect as a basis for Modern Mandarin.
