The creative basis of Water Margin;
In the Southern Song Dynasty, the story of Liangshan heroes was widely circulated. At that time, Gong Kai, a painter and writer, wrote a preface to the praise of thirty-six people in Song Jiang, saying: The stories of thirty-six people including Song Jiang have spread all over the streets; Painters also write pictures and shadows for them.
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.
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.
