Abstract:Du Heng was a “comrade” of left-wing writers before he joined in the controversy about the “Third-group Man”. He was arrested for participating in revolutionary activities when he was young, and his literary works were mainly about the lives of the unpriviledged people. He also expressed the confusion and difficulties of revolutionaries and their aspirations for a better life in the future. Du Heng was deeply influenced by the left-wing writer Feng Xuefeng and was ideologically inclined to the revolution. However, after the “Free Argument about Literary and Artistic Issues”, the left-wing writers began to move away from Du Heng for the sake of discourse strategy, so Du Heng’s revolutionary novel Brighter was given a cold shoulder. Du Heng finally drifted away from left-wing writers and even from his friends.
