On March 1944 and 19, Guo Moruo's "Three Centennial Festival of Shen Jia" was published in Chongqing Xinhua Daily for 4 days. At that time, War of Resistance against Japanese Aggression had changed from a strategic stalemate to a strategic counterattack. Under the leadership of the Chinese Productive Party, the people of China are making every effort to win the final victory in the War of Resistance Against Japanese Aggression and to build a free, democratic, independent and prosperous new China. In order to meet the victory and promote the struggle, Guo Moruo wrote the Three Hundred Years Festival of Shen Jia in commemoration of the 300th anniversary of the peasant uprising led by Li Zicheng. He was the first to sum up the reasons, experiences and lessons of the peasant uprising led by Li Zicheng with the scientific attitude of Marxism-Leninism. The full text can be roughly divided into three parts. The first part explains that political corruption, severe famine and coma in Chongzhen in the late Ming Dynasty led to civil strife and national subjugation. The second part describes the uprising troops in Li Zicheng from small to large, which eventually overthrew the Ming Dynasty and occupied Beijing. Among them, the study on the experience and important role of Yan Li, an intellectual, is particularly detailed. The third part shows that after Li Zicheng entered Beijing, he ignored Yan Li's ideas, was carried away by victory, ignored the enemy and ignored policies, and some leaders' lives were corrupt, sectarian struggles occurred from time to time, and finally failed. After the article was published, it immediately attracted the attention of Mao Zedong and the Central Committee of the Communist Party of China. Mao Zedong pointed out many times that we should learn from the history of the Li Zicheng Uprising, and instructed that "The 300th Anniversary of Shen Jia" should be regarded as one of the documents of the national rectification movement. This article has been printed into a single book many times in Yan 'an and various liberated areas, which has a great influence.
