Lu Xun is an outstanding novelist in the history of modern Chinese literature, the sense of picture formed by the novel language is one of the important marks of his works. The sense of picture is the product of the organic integration of Lu Xun’s painting art and novel language, it is also the meeting point of Lu Xun as a "writer" and an "artist", and also the new perspective of the research of Lu Xun. Lu Xun creatively combined literary thinking with artistic thinking, applying the creative concepts and techniques of line drawing, woodcut, ink painting and cartooning to his novels, so that the language of his novels presented a sense of picture with different artistic styles. Among them, the precise and vivid pictures drawn in line drawing are the manifestation of realism, the profound and grim pictures formed by the taste of woodcuts are the "beauty of force" of modernism, the poetic freehand pictures created by the tone of ink painting styles contain the aesthetic charm of Chinese classicism, and the exaggerated symbolic pictures practiced in comic drawing styles are tongue in cheek and expressiveness of postmodernism. The sense of picture brought by novel language is a precious wealth left by Lu Xun to Chinese modern and contemporary literature. Its characteristic of "painting in the text" has been gradually felt and recognized by people. Exploring the creative mechanism of the organic integration of language and painting in Lu Xun’s novels can re-recognize the dual identity value of Lu Xun’s novelists and artists, thinking about the modern transformation of ancient poetry and painting theory, and explore the new path of "poem and picture reflecting each other" opened up by the "combination of painting and text" in the modern literary context.
