The Dayong Dynasty was founded for more than a hundred years and passed through four emperors. It is currently in the "Jinghe Period", which is the middle period of the dynasty. Taizu unified the world by force and designated the capital city as "Shangyong City". However, in order to appease all forces at the time of the founding of the country, the "Three Northern Domains" (Yanyun, Shuofang, and Hedong) and the Jiangnan noble clan group (headed by the Xie, Lu, and Zhou families) were retained, forming a tripartite check and balance pattern of "central imperial power - feudal towns - noble clans." Emperor Jinghe had been on the throne for five years and was nearly 40 years old. He had a gentle but indecisive personality. On the one hand, he wanted to weaken the military power of the vassal and restrict the land annexation of the nobles. On the other hand, he relied on the two forces to stabilize the court, which led to undercurrents in the court. There were "barbarians" in the north who often went south to plunder, the border armaments were depleted, local officials were corrupt, it was difficult for poor scholars to be promoted, and there was a hidden refugee problem among the people.
