The entire imperial court had thirty-six prefectures in the Nine States, and every prefecture city was under the jurisdiction of the conferred Heavenly Dao Perfected Lord. Further down, the counties and towns were managed by the county officials and the City Gods of Yin. Then, there were the River God, Mountain God, Land God, and so on.
Under normal circumstances, the two prefectures minded their own business. For example, Huaishan Prefecture was next to Huaiyang Prefecture, and the main water flow of the Zejiang was in Huaiyang Prefecture. On the other hand, a small branch of the Huaishui flowed into Huaiyang Prefecture.
