Research on the division of Shannan East Road in the middle of Tang Dynasty

The Shannan host road in the early Tang Dynasty was mostly a whole. After the Rebellion of An and Shi, under the influence of the control system, the Shannan East Road began to be divided into Shannan East Road centered on Xiangyang and Jingzhou (Jiangling). The division of Shannan East Road was followed by the adjustment of their respective administrative areas and policies. Under a series of adjustments of the Tang Court, Xiangyang gradually turned into a military town, and Jingzhou gradually became an important financial area of the Tang Dynasty.
