In the sixth year of Guanghe reign at the end of the Han Dynasty, Liu Yu was a descendant of King Jing of Zhongshan. He encountered officers and soldiers and killed good people and took credit for his actions, activating the Liangshan system - Zhao Guan Sheng Lin Chong Qin Ming Dong Ping Hu Yanzhuo retreated the enemy and collected the remaining soldiers to build a mountain stronghold. Taking advantage of his status as a clan member, he surrendered to Liu Bei and offered his policy of "pacifying the Yellow Turbans first and then taking back the Bingzhou border cavalry", and secretly formed an alliance with Zhao Yuntianchou to practice Youzhou's sudden cavalry. After being granted the title of Zhongshan Marquis by Han Zen, the law of equalizing land and restricting slaves and maidservants was imposed.
