Water margin is one of the four famous novels in ancient China. It was written in the late Ming Dynasty and reflected the dark side of society and the suffering of the people. The following is the social background of the Water Margins: 1. Late Ming Dynasty: Political corruption and social contradictions intensified in the late Ming Dynasty. The corrupt officials of the imperial court were extremely greedy and wantonly extorted money to oppress the people. At the same time, foreign invasions and wars were frequent, and social order was chaotic. 2. Peasant Uprising: At the end of the Ming Dynasty, the peasants continuously launched uprisings such as the Yellow Turban Uprising, the Turban Army Uprising, and the Taiping Heavenly Kingdom Uprising. Although these revolts were not large-scale, they all attempted to overthrow the corrupt imperial court and establish their own regime. 3. Thieves: Thieves take the opportunity to rob and harass the people. The society was in chaos and the people were living in poverty. Class contradictions: During this period, the social class contradictions were sharp. The class contradictions between poor peasants and corrupt officials, as well as between peasants and foreigners, were very serious. Based on the above social background, the heroes of Liangshan described in the Water Margins were fighting against corrupt officials and foreign invasions, but at the same time, they were also facing the oppression and threats of thieves and poor farmers. Therefore, their righteous acts and actions also reflected the contradictions and complexity of society at that time.
