Shannan Road Shannan Road from the points. The first year of Zhenguan (AD 624), Tang Taizong according to topography and division of the military region unified deployment, a total of 10, Shannan Road is one. Tang Rui Zong Jingyun two years (711 years), under the jurisdiction of Shannan Road is very wide, divided into Shannan two things. Tang Xuanzong time for the world, Shannan East Road, jurisdiction over 17 states. At this time of the Shannan host is still monitoring area, truly become a feudal Jiedushi in the Tang Dynasty Suzong's first year (756).

On the status of Shandan Jiedushi, Zhou Shangbing made a study - "the early Tang Dynasty Shannan host - and the early Tang Dynasty Han River middle reaches of the strategic position," Ren Daixi - "the early Tang Dynasty politics Shannan, Jiannan area, "an article on the whole Shannan region's important position, especially the status of economic traffic made a discussion. In the early Tang Dynasty, Shannan and Shonan were the main areas of Jiedushi's jurisdiction. The Shonan prefecture in the early Tang Dynasty actually included the later Jingnan Jiedushi. But Shannan host Jiedushi status is still very important.

(一) Military status

Shannan host Jiedushi is located in the Central Plains, the defense should not have the responsibility of Heshuo town, but an important geographical location, is connected to the traffic arteries around the two with Ziqing Township phase, and the Heshuo township also Not far, so Shandan host Jiedushi has a defense of the responsibility of the town of Heshuo. Its legacy of Xiangyang military position is since ancient times it will be valued, "Jing Xiang of the old, west benefits, beam, and off, Long Zhichi, north to Los, river, not profit thousands of miles, soil fertile Tian Liang, Fang Cheng steep , Water circulation, transit without delay, into the Qin Zhao can be swept back can be guaranteed high. "Jingxiang according to Jiang left high, west of Pakistan, Sichuan, North control off, Luo ... ... no Jingxiang not founding."

As a traffic thoroughfare, not only convenient water transport, transport the court to pass the southeast of the land here, but also contributed to the development of commercial trade, the commodity economy to obtain development opportunities.

Since the status of Jiedushi to Shonan is very important, so since the establishment of the court to try to control, sent a lot of heavy minister Jiedushi, although most of the Shonan host Jiedushi are subject to court control, very few against the court . However, compared to other court control of the feudal lords, the Shannan host Jiedushi there are more mutiny and rebellion, as Liang Chongyi separatist participation in the four town of chaos and so on.
