Political System of China (Tang Dynasty)

    The prosperity during the Tang Dynasty profited from its enlightened political system: comprehensive administration and official system, strict legal system, and equitable imperial examination system.
    The Tang Dynasty (618 - 907) initiated the organizational structure 'Dao' and 'Fu' to divide the political districts. During Zhen Guan's Reign, the national territory was divided into ten political districts called 'Dao', which increased to 15 in the Heyday of Kaiyuan. The subordinate political districts were called 'Zhou' or 'Fu'. The more subordinate administrative structure was in turn 'Xian' (town), 'Xiang' (five 'Li's), 'Li' (a hundred families), 'Cun' (village), 'Bao' (five families) and 'Lin' (four families). At the end of Kaiyuan reign, there were 328 'Zhou's and 1,573 'Xian's.
    The official system of the Tang administration involved the central official system and local official system. The central official system followed the Sui Dynasty's (581 - 618) Three Departments and Six Ministries system. In addition, nine 'Si's and five 'Jian's were set up to work with the six ministries. The local official system was in line with the political administrative structures, of which the chief official title were called 'Guancha Shi' (observer of Dao), 'Ci Shi' or 'Tai Shou' (chief officer of Zhou), 'Xian Ling', 'Qi Lao', 'Li Zheng', 'Cun Zheng', 'Bao Zhang' and 'Lin Zhang'.     This article shows how the the Tang Dynasty set up their political system. China has a very old and organized political system and it has gone through many tweeks and changes... This is one of the earlier set ups and it was very organized.
