In the Southern Song Dynasty, the story of Liangshan heroes was widely circulated. The earliest blueprint of Water Margin is the legacy of Xuanhe in Song Dynasty, which focuses on the main characters such as Yang Zhi selling knives, Chao Gai ganging up to grab the birth outline, Song Jiang killing and Lin Chong, jy, and He Lu. During the Song and Yuan Dynasties, there were many stories adapted from Water Margin.
Shi Naian sorted out and processed the stories and characters in Water Margin, and faithfully accepted the views of the people in the process of writing Water Margin, which is the ideological basis for the great achievements of Water Margin.
