At the end of the Ming Dynasty, the society was pedantic, officials were rampant, taxes were heavy, people were in dire straits, people were in dire straits, Qing troops entered the customs, and war broke out everywhere.
The government was weak and incompetent, oppressing good people internally, and retreating steadily externally. Officials at all levels deceived the subordinates, and the people dared not speak out. In 1627, hungry people rioted in Chengcheng, Shaanxi, which kicked off the civil uprising in the late Ming Dynasty. There were rebellions one after another, and the society was in chaos. Emperor Chongzhen knew that corrupt officials had led to the decline of the Ming Dynasty, so he appointed the eunuch Cao Songyang to recruit righteous people nationwide and set up an anti-corruption team to eliminate corrupt officials and treacherous officials to save his fate.
