The viceroy system was a unique local political system in Wei, Jin, Southern and Northern Dynasties. As for the origin of the viceroy system, He Ziquan's Zhong Jun in Wei and Jin Dynasties (Reading History Collection, Shanghai People's Publishing House, 1982 edition) holds that the viceroy system originated from the imprisonment system in the Cao and Wei Dynasties and was established in the early years of Wei and Huang Dynasties. Tang Chang Ru's "The enfeoffment System in the Western Jin Dynasty and the Emperor's Exiting the Town" (Notes on the History of Wei, Jin, Southern and Northern Dynasties, Zhonghua Book Company, 1983 edition) holds that the title of viceroy had been institutionalized before Cao Piyankang proclaimed himself emperor in the first year. Zhang Zhuo's Tracing to the Origin of the DuDu System in the Northern Dynasties (No.2, Research on the Northern Dynasties 199 1) holds that the DuDu system originated from the DuDu system in the Eastern Han Dynasty. In the second year of Huang Chu's stay in Wei Wendi, after the official system stopped, the position of viceroy was officially independent and finally determined, and a complete viceroy system was established in 265. There are two characteristics: first, the division of Dou Du District was customized after two changes; Second, Doudutun camp gradually fixed after the war stabilized. However, Chen's Origin and Stereotype of the Governor System in Cao and Wei Dynasties-On the Relationship between the Central Government and the Local Government (Journal of Beijing Normal University, No.5, 1996) holds that the governor's "supervisor" since the Eastern Han Dynasty is supervision, and the governor's "supervisor" in later generations is supervision and command. The two names are the same, and it is pointed out that there are three signs in the establishment of the viceroy system. The first two items existed in the first year of Huang Chu, and the third item completed the transformation process at the end of Jian 'an. Therefore, the establishment of the governor system should be in the first year of Huang Chu. Yao Nianci's "A Preliminary Study of Cao Wei Local Generals" (Historical Records, Literary Works No.5, 1987) holds that the governor system came into being to control and use Hao Shuai and strengthen local control. After Wei Wendi's handling, the state's control over the county has become a custom around Ming Di. Xue's The Establishment and Function Transformation of the DuDu System in Wei and Jin Dynasties (Journal of Tianjin Normal University, No.4, 1992) holds that the Wei and Jin Dynasties are an opportunity for the establishment of the DuDu system. After Cao Pi ascended the throne, in order to ensure the smooth transfer of power, two major problems must be solved, namely, the instability of the local situation and the prevention of the invasion of Wu and Shu. Cao Pi took advantage of Cao Cao's experience in controlling local areas and dealing with Wu and Shu during Jian 'an period, and gradually established the viceroy system.

As for the governor system in Wei, Jin and Southern Dynasties, Chen's On the governor system in Wei, Jin and Southern Dynasties (Journal of Beijing Normal University, No.4, 1986) divides it into four stages: formation, establishment, development and decline. During the Jian 'an period, it came into being to control the local powerful armed forces. It was formally established in the first year of Huang Chu, Wei Wendi. The rebellion of the Eight Kings in the Western Jin Dynasty led to its abnormal development. From a military commander who simply ruled the army to a local governor who ruled the army and the people, the integration of military and political affairs is superior to the state. The Southern Dynasties entered a stage of decline, from the tool of central control of local strongmen to the representative of local political forces opposed to centralization. Xue's "Establishment and Function Transformation of DuDu System in Wei and Jin Dynasties" (Journal of Tianjin Normal University, No.4, 1992) holds that after the unification of the Western Jin Dynasty, the function of DuDu changed from a reserve to a tool for the imperial court to control the local area. Due to the establishment of the viceroy in all parts of the country, it officially prepared for the evolution of the viceroy area into an administrative area above the state, and it completely evolved into a local separatist force at the end of the Western Jin Dynasty. Yao Nianci and Qiu Curie's "A Brief Account of the Evolution of the DuDu System in Jin Dynasty" (Journal of Beijing Normal University, No.2, 1988) holds that in the early Western Jin Dynasty, the power of the DuDu was strengthened by adjusting the jurisdiction, setting up military advisers, limiting its personnel, finance and dispatching power, thus contributing to the consolidation of political power and national unity. But at the same time, the viceroy has the privilege of being a soldier and an official, which is eroding the viceroy system. The Eight Kings Rebellion completely subverted the nature of the local governor system and became a local separatist force against the central government. Zhang's "Discussion on the Military System of the DuDu State during Yongjia and Jianxing Years in the Western Jin Dynasty" (historical data set 200 1No. 1) holds that during Yongjia and Jianxing years, Emperor Huai set up garrison areas in important areas of the country to save the precarious Western Jin regime, but either because of the weakness of the DuDu area itself or both.

The governor-general system in the northern dynasties, its total control of deformation and runway system. Zhang Zhuo's "Northern Dynasties DuDu System" (Northern Dynasties Studies,No. 1989,No. 1) holds that the Northern Wei DuDu system began with Emperor Tuoba Gui of Daowu, was established by Emperor Tuoba Tao of Wutai, was perfected by Emperor Xiaowen Justin and Xuan Wudi Yuanke, and was out of balance with Emperor Xu Yuan of Xiaoming. The commander-in-chief system of the Eastern Wei and Northern Qi Dynasties was extremely chaotic. In the second year of Wuping after Qi Dynasty, Prime Minister Zucong tried to adjust, but ended in failure. The presidential system in the Northern Dynasties-On the establishment of the military government of Zhou and Sui Dynasties (published in the second half of 0990, and studied in the Northern Dynasties, 65438) holds that the presidential system in the Western Wei Dynasty and the Northern Zhou and Sui Dynasties is the continuation and modification of the system of the northern Wei Dynasty, which first appeared in the Western Wei Dynasty where the system of the governor-general was extremely chaotic, and the presidential system was established in the first month of the first year of the Northern Zhou Dynasty. The emperor reigned for nine years, and the whole country was unified. The general political department of the Sui Dynasty spread all over the country, and the general control reached its peak. During the great cause of Yang Di in the Sui Dynasty, the presidential system and the knighthood system were abolished, ending the system of the commander-in-chief (general manager) military region that had been implemented for nearly 400 years in the Wei, Jin, Southern and Northern Dynasties. Gai Jinwei and Wang's Research on the System of the Northern Zhou Dynasty (Journal of Xinjiang Normal University, No.3, 2003) carefully sorted out the literature, made a detailed analysis of the reasons, distribution, types, status, selection of officials, subordinates and positions of the Northern Zhou Dynasty, and outlined its structure and characteristics. On the basis of Yang Shoujing's Geography Examination of Sui Shu and Cen's Seeking Truth, Yan Gengwang's Textual Research on the Governor's Mansions in Sui Dynasty (Chronicle of China 6th Edition) makes a detailed textual research on the establishment, management areas, current locations and predecessors of the 64 Governor's Mansions in Sui Dynasty. Mou Fasong's Textual Research on the Local Officialization of the Northern Dynasties (33 Series of Literature and History) holds that the local bureaucratization of the Northern Dynasties originated in the Sixteen Kingdoms period, and Yan Qian, Hou Yan's stay in Longcheng and Hou Yan's succession to Taiwan marked the initial progress of the local bureaucratization of the Northern Dynasties. The establishment of Zhongshan Station in the early Northern Wei Dynasty inherited and developed the trend of their transition to local institutions. From the Serina Liu Uprising to the East-West Division in the third year of Yongxi, the Taiwan system developed rapidly, and the process of local bureaucracy was basically completed. During the Northern Qi Dynasty, the platform was fully mature and shaped into the highest-level local institution. The platform basically covers the whole country, and its jurisdiction is relatively stable. The Chief Executive has jurisdiction over the State Secretariat, and his authority is recognized by law. The Local Stations in the Eastern Wei and Northern Qi Dynasties (No.9 Historical Materials of Wei, Jin, Southern and Northern Dynasties, 10) further demonstrates the institutionalization and localization of the Northern Qi Dynasties by investigating the formation, layout and status of the eight stations set up in the Eastern Wei and Northern Qi Dynasties. Jin He's Investigation on the Institutions and Principal Officials of the Northern Wei Committee (Journal of Cangzhou Teachers College,No. 1 2002) holds that the task of the Northern Wei Committee is relatively simple and specialized.
