China experienced more than 2,000 years of an imperial system, and finally, the Xinhai Revolution broke out in 1911, ending the imperial system. Because of this turning point, China slowly moved from tradition to modernity. Then came the May Fourth Movement and the New Culture Movement, which brought the wave of China's modernization to its peak, driven by writers and writers, Lu Xun being the most prominent representative. Drawing on the research results of scholars at home and abroad, this paper discusses the modernity expressed in Lu Xun's works. Starting from some of Lu Xun's well-known works, this paper combines the transformation of Lu Xun's works in structure and content to study how Lu Xun's works shift from tradition to modernity. In the end, this paper yielded the result: the new form of modern novels established by Lu Xun's novels is the result of drawing lessons from foreign novel forms and Chinese traditional literary and artistic experience, combined with his unruly creativity, to achieve the unity of "inheriting tradition" and "breaking through tradition".
