简介：In the early Ming Dynasty, Jining was the prefecture, covering 3 states and 12 counties. In the eighteenth year of Hongwu (1385), the prefecture was changed into a state, and only the three counties of Jiaxiang, Juye and Yuncheng were under its control. At the same time, Yanzhou was promoted to Yanzhou Prefecture, stationed in Ziyang County, and controlled 27 states and counties. Jining is under the jurisdiction of Yanzhou Prefecture.
