During the War of Resistance Against Japan, Chen Du-xiu appealed for developing capitalism in China and criticized the thought of populism deeply. Although he made great mistakes in his political inclination and hadn't e-nough knowledge of developing capitalism in China,his criticism to populism in theory was profound and it made a great contribution to the propagation of the scientific socialism. It was also consistent with the CPC's tradition of criticizing populism and had great coherence with Mao Ze-dong's ideas in this period in some aspects. Therefore,Chen's idea will play an important role in Chinese modern thought history and Marxist thought history.
