In the history of China, the system of "three provinces and six departments" was implemented, which was a division of administrative power. It was a perfect system from the Han Dynasty and was established from the Sui Dynasty to the Tang Dynasty.

Three provinces: Zhongshu Province, Menxia Province and Shangshu Province.

Six departments: official department, household department, ritual department, military department, criminal department and industrial department. Six departments directly under four departments, a total of 24 departments.

The three provinces in the Tang Dynasty were central government agencies, which generally made decisions in books, audited them under the door and executed them. The governors of these three provinces are the secretaries of the Central Committee (Sui as the internal historical order), the servants of the Central Committee (Sui as Ran) and the secretaries of the Central Committee. The governors of the three provinces discuss state affairs together and serve as prime ministers. The place where they discuss politics is called the government hall.

The six departments are the central administrative organs under the provincial government, in charge of all aspects of government affairs and the implementation of government decrees, and have leadership and supervision over the nine temples and five prisons, as well as local governments and prefectures.

The official department is responsible for the appointment, removal, examination and transfer of national officials. The Ministry is in charge of land, taxation, household registration, military supplies, salaries, food, fiscal revenue and expenditure, etc. The ritual department is in charge of the ritual system of the five rites and the method of proofreading tribute.

The Ministry of War is responsible for selecting military officers and ranks, ordnance, military orders, etc. The penalty department is responsible for the national penalty laws and regulations and reviewing the names of criminals. The Ministry of Industry is in charge of construction projects.

There are 6 central directly under the authority and 24 departments.

There are four divisions in the official department: official department, official department, official department, official department, official department and official department.

The four departments of the household department: the household department, the branch department, the finance department and the warehouse department.

The ceremony consists of four divisions: the ceremony department, the ancestral department, the catering department and the guest department.

The penalty department consists of four divisions: penalty division, penalty division, penalty division, penalty division and penalty division.

Many functions of the nine monasteries and five supervisors are consistent with those of the twenty-fourth division of Part VI of Xia Jun. The competent decrees of six departments and twenty-four departments are regarded as government organs; Nine monks and five supervisors are respectively responsible for specific affairs in a certain aspect and are regarded as affairs organs.

The affairs department has to implement government decrees, so these two systems are related. At the same time, the functions and powers of the six departments and the nine halls and five prisons overlap a lot, and there is a division of labor and restriction in actual operation.

Nine temples:

Taifu Hall: in charge of palace storage and trade.

Zongzheng Temple: Manage the royal family affairs. Taoism was the state religion in the Tang Dynasty, so Zongzheng Temple also managed Taoist priests and couples.

Sinong Temple: in charge of grain storage, granary management and rice supply to officials in Beijing and North Korea.

Taichang Temple: the highest administrative organ in charge of rites and music.

Among the five prisons in the Tang Dynasty, the military equipment prison and the water prison were sometimes abolished, and sometimes they were only called the three prisons, and they were called the nine halls and three prisons together with the nine halls.

The Song Dynasty followed the system of the Tang Dynasty and set up three provinces and six departments. Only Zhongshu Province was retained in the Yuan Dynasty. Later, Zhu Yuanzhang abolished Zhongshu Province in the Ming Dynasty, and the emperor directly led six departments. The Qing dynasty followed the Ming system, and three provinces and six departments withdrew from the historical stage.
