Things have to start from after the destruction of Shu. Wang Quanbin led the army into Sichuan, and Song Taizu earnestly warned: "You don't have to burn down houses, expel officials, develop graves and cut down Santo." However, Song Jun's conquest of Shu was arrogant and illegal, killing thousands of innocent people. The people's sentiments are passionate, and people's uprisings break out one after another. While severely punishing the relevant personnel, the Song regime sent Mao's younger brother to Shuzhong to comfort him, while promising to reduce taxes and promote talents to be officials.
