In fact, Lu Xun and Guo Moruo started a debate on revolutionary literature in 1928. They had never met before. Although they disagree privately, they have yet to write a critical article. At that time, Guo Moruo's Literary Association, Creative Society and another literary group, the Sun Society, jointly launched a revolutionary literary movement. In the process, they ridiculed and criticized Lu Xun. Guo Moruo's work criticizes Lu Xun's "My Attitude, Compassion and Age" and lashes out at Lu Xun.

In this article, Guo Moruo gave Lu Xun three hats, namely feudalism, double counterrevolution and fascism. These three hats seemed a bit cruel at the time. In the article "Fortress Besieged", Guo Moruo's words are the most intense. Therefore, Lu Xun and Guo Moruo had hatred, but as early as February 1928, Guo Moruo was angry because I wrote an article "Look at Chiang Kai-shek Today" on April 12, 1927. At this time, Guo Moruo had gone into exile in Japan and devoted himself to studying ancient Chinese culture.

The debate between them was basically Lu Xun’s one-man show. It was not convenient for Guo Moruo to answer, so there was no more intense conflict. In August 1931, Lu Xun gave a speech at the Shanghai Social Sciences Association, mentioning and criticizing Guo Moruo's Creative Society many times. At the beginning of the article, Lu Xun traced the historical process of the gangsterization of talents in Shanghai. He believes that creating society is a new school of talents, and his ideas of change can also be called rogue. Because Lu Xun's speech was harsh and even exaggerated the facts, he poured out his hatred for the Creative Society and Guo Moruo, which had a great impact.

They were quickly translated into Japanese and published in Japan. Guo Moruo saw Lu Xun's articles in Japan. So Guo Moruo wrote "Ten Years of Creation", indignant and counterattacking Lu Xun. Afterwards, they attack each other. In general, the debates on both sides are taken out of context and the hats are suspicious. However, as the conflicts between China and Japan continue to deepen, the conflicts between China and Japan in literature, thought, etc. tend to ease, and as time goes by, their pen and ink debates also disappear.
