In the 1920s, proletarian literature flourished in East Asia. The left-wing ideology and literature of various countries have produced multi-direction exchange and interaction, which has constructed the transboundary exchange network(domain) among the left-wing literature of East Asia and formed the mutual observation of seeking the same spirit. Among them, there are extensive and close exchanges and interactions between the League of Left-Wing Writers led by the CCP and the international proletarian literature camp, especially the left-wing literature league of Japan and Korea, which have close geographical relations with China, to a certain extent, formed mutual observation. This paper takes “the Five Leftist Martyrs” who were secretly killed by the Kuomintang in Shanghai on February 7, 1931 as an example, and tries to expatiate the joint consciousness formed among the left wing literary circles in East Asia at that time through their related literary works and the reaction caused by the bloody sacrifice event in the literary circles of Japan and Korea. Although this kind of consciousness may not have formed large-scale interaction due to the suppression of Japanese domestic militarism and the high-pressure rule policy of Japan in colonial Korea, it exists in the crevices with great significance and value in itself. It is still valuable for us to study the relationship between East Asian left-wing literature, seek common value identification, and promote mutual exchange and cooperation. At the same time, the attention of various countries' literature to the Event of “the Five Leftist Martyrs” not only played a positive role in the communication between different countries' literature, but also provided an important basis for us to seek dialogue today.
