"Water Margin" literally means "waterside" or "the other side of the water". The entire theme of "Water Margin" is to tell the story of those "heroes" who cannot find a way out in normal society. "Eight Hundred Miles of Liangshan Po" is their settlement, that is, "Water Margin".
"Water Margin" tells the story of Song Jiang, Wu Song, Lin Chong, Lu Zhishen and other heroes who were unable to live in a normal society due to various reasons, and their way out of life was cut off. "Liangshan" became the only way out and settlement for these heroes. When the "One Hundred and Eight Generals" successfully gathered in Liangshan, how to develop next became a new problem, and they looked for a new way out under the leadership of Song Jiang.
Extended information:
"Water Margin" first came from "The Ancient Duke and Danfu came to court and led the Western Water Margin to Qixia" in "The Book of Songs Daya Mian" . It is the story of Zhou’s ancestor Danfu. At that time, it was the heyday of China's Shang Dynasty. There was a Chinese tribe named "Zhou" living on the northwest border of the Loess Plateau. Because the surrounding Rongdi people often come to invade, the Zhou tribe suffers from fear and danger every day.
About the time when Wu Ding of the Shang Dynasty was in his prime, an outstanding leader emerged from the Zhou tribe - King Gu Gong Danfu of Zhou Taiwang. Under the leadership of their father, the Zhou tribe went through hardships and migrated to Zhouyuan (today's Baoji City, Shaanxi Province). The Zhou tribe basically got rid of the intrusion of Rong and Di here, began to develop and grow, and eventually established the Zhou Dynasty, which had a far-reaching influence in Chinese history.
"The Book of Songs Daya Mian" is a poem used by the Zhou people to commemorate and praise Dan's father's contribution to the development of the Zhou tribe. The word "Water Margin" in the poem refers to the place where the Zhou tribe later lived and developed. Zhou Yuan. Therefore, the meaning of the word "Water Margin" is "a way out" and "a place to settle down".
