Ministry of the Interior –

He is responsible for the service and supply affairs in the palace.

The chief is called Chang Qiu Supervisor, and the deputy title is Chang Qiu Ling. The subordinate officials include the internal counselor, the inner temple uncle, the inner counselor, the temple person, and the servant, and the management of the six bureaus, including Shangshi, Yeting, Gongfu, Xi Guan, Inner Servant, and Inner Government.

Because the role of these two provinces is not so important, people usually refer to the political system of the Sui Dynasty as the "three provinces and six ministries system", and the three provinces and six ministries are the highest decision-making and administrative organs of the central government!

The Sui Dynasty generally formed a group of prime ministers from the heads of these three provinces (Neishi, Menxia or Zhongshu and Shangshu) to assist the emperor in handling state affairs. In addition to the heads of the three provinces in the Tang Dynasty, such as those with official titles of "Tongzhongshu Menxia Sanpin" and "Tongzhongshu Menxia Pingzhangshi" (Wu Zetian era changed to "Tongfeng Pavilion Luantai Sanpin" and "Tongfeng Pavilion Luantai Pingzhangshi"), they were also prime ministers.

Compared with the present, the principal heads of these three provinces and the "three products under the door of the same Zhongshu" and "the three products of Luantai in the same Fengge" are prime ministers; "Tongzhongshu Menxia Pingzhangshi", "Tongfeng Pavilion Luantai Pingzhangshi" and a small number of deputy heads of the three provinces (some are not) are vice premier-level prime ministers.

Because Shangshu Province is an organ that implements the heavy government affairs of the state, it has six departments: the Ministry of Officials, the Ministry of Rites, the Ministry of War, the Duguan (the Ministry of Punishment in the third year of the Emperor's reign), the Duzhi (the Ministry of Civil Affairs in the third year of the Emperor's reign, and the Tang Dynasty changed its name to the Ministry of Households due to the avoidance of Li Shi's "people"), and the Ministry of Industry.

Each ministry is responsible for the implementation of government affairs and decrees related to itself, and has the power and responsibility to lead and supervise the nine temples and five superintendents responsible for specific affairs of the central government and the local prefectures and counties.

The six ministers are Shangshu, and the deputy governors are called Shilang.

(During the Wu Zetian period, some restructuring was made to the three provinces and six ministries of the central government.)

As the queen of heaven period, Menxia Province was located in the east of Miyagi and changed to Dongtai, Zhongshu Province was located in the west of Miyagi and changed to Xitai, and Shangshu Province was renamed Zhongtai in the center; The east and west are called left and right in ancient times, so the former head of Dongtai is the left minister, the former head of Xitai is the right minister, the former head of Shangshu Province is Kuang Zheng, the original left and right Cheng are Suji, the original six Shangshu are the big Changbo, and the waiter is the young Changbo; The remaining 24 divisions, the imperial history platform, the nine temples, the seven eunuchs, the sixteen guards, etc., all changed their names according to the meaning of their functions.
