The contradiction between the central imperial power and the local gentry gradually emerged. Official corruption was common, excessive taxes and excessive taxes were imposed, wars remained in remote states and counties, banditry was frequent, and people's livelihood was in decline. Characteristics of Yunxi County: It is located at the junction of two states, with complex terrain, barren arable land, and is controlled by local powerful people. The government is chaotic. Former county magistrates have been investigated for corruption or have been squeezed out by powerful people. The county government is short-staffed and the people are displaced. It is a typical "mess".
