On this day, 34 years ago, on March 26, 1991 (February 11, 1991 in the lunar calendar),"The Original Book of the Water Margin", which Luo Ergang spent 60 years researching and revising, was released. In March 1991, the famous historian Professor Luo Ergang spent 60 years researching "The Original Book of the Water Margin" was published. He believes: "The author of" Water Margin "is actually Luo Guanzhong. "Water Margin" originally lasted for seventy chapters, until the stone tablet of Juyi Hall received astronomy and the heroes of Liangshanpo were horrified by nightmares. It is an immortal masterpiece that resists feudal rule and preaches peasant uprisings." He believes that this edition was written from the end of Hongwu to the beginning of Yongle in the early Ming Dynasty. The 100-chapter edition of "Loyalty and Loyalty Water Margin" was continued and stolen by literati after Xuande and orthodoxy in the Ming Dynasty. Luo Ergang restored the original appearance of the stolen additions and corrections in the book based on the results of the examination and revision, and noted them one by one. Professor Luo Ergang said: "The biggest research achievement of my life is the revision of" Water Margin ".
