What are "internal historical sequence", "domestic province" and "historical province"?

Zhongshu Province, Menxia Province and Shangshu Province are the highest administrative departments, collectively referred to as the three provinces.

1, Zhongshu Province is mainly responsible for drafting imperial edicts according to the emperor's will. To put it bluntly, Zhongshu Province is the decision-making body;

2. Menxia Province is responsible for reviewing the imperial edict and is the deliberative body (with the right to veto).

3. Shangshu Province is responsible for undertaking imperial edicts and is the executing agency.

This is the principle of division of labor among the three provinces, thus restricting each other. Among them, the chief of Zhongshu Province is called Neishi Order, which was renamed Zhongshu Order after the Tang Dynasty. The master of the province under the door was renamed Shi Zhong in the later Tang Dynasty. The chief of Shangshu Province is called Shangshuling.

Three Provinces and Six Departments System: It is a set of tightly organized central official system in China's ancient feudal society. It was established in the Sui Dynasty, and the six-part system remained basically unchanged from then until the end of the Qing Dynasty. The three provinces refer to Zhongshu Province, Menxia Province and Shangshu Province.

The six departments refer to the official department, the household department, the ritual department, the Ministry of War, the Ministry of Punishment and the Ministry of Industry. Before the Sui Dynasty, from the Western Han Dynasty to the Southern and Northern Dynasties, the official system of the Qin Dynasty was basically used. After Emperor Wendi ascended the throne, in order to strengthen centralization and integrate various systems of the previous generation, a system of three provinces and six departments was established.

During the period of Emperor Wendi of Sui Dynasty, there were three provinces and six departments, and the governors of the three provinces were equal to the prime ministers of Qin and Han Dynasties. Dividing the post of prime minister into three parts avoids the autocratic power of ministers and further strengthens centralization.
