Zhangjiakou City, Hebei Province‖The former site of Chahar General Office.

Chahar Military Governor's Office, located in Qiaoxi District, Zhangjiakou City, was built in the 27th year of Emperor Qianlong's reign in the Qing Dynasty. It was the earliest of the three military governor's offices set up by the Qing court across the country (Chahar, Urumqi, and Rehe), and it is also the only survivor today. The garrison generals and commanders-in-chief of the Eight Banners in the Qing Dynasty were of the first rank. Because they are stationed in a certain place, they have the inherent responsibility to defend the territory and borders. In addition to the Green Camp soldiers, the Qing court made several changes, and by the Qianlong period, there were 14 generals and 3 commanders-in-chief across the country. The Eight Banners soldiers were used to intimidate the local areas to maintain a unified ruling situation. Chahar is located in the northwest of Beijing and has a very important geographical location. Stationing troops here can not only protect the capital, but also deter Mongolia south of the desert. After the "Buruni Incident", the Qing government organized the Chahar people into general banners, "officials were not allowed to be hereditary, and they were not allowed to take charge of matters on their own", and set up the Chahar General to govern the area, keeping the region firmly in its hands. Since its construction, it has served as the seat of Chahar Governor's Office, Chahar Special Administrative Region Governor's Office, Chahar Provincial Government of the National Government, the pseudo-Chahar Autonomous Government of Southern China, the pseudo-Mengjiang United Autonomous Government (also known as "Prince De's Palace" because the Mongolian prince Demchugdongrub moved in), the Shanxi-Chahar-Hebei Border Region Administrative Committee, the Kuomintang Chahar Provincial Government, the New China Chahar Provincial Government, and the Inner Mongolia Autonomous Region Government. From the establishment of Chahar Governorate in 1762 to the abolition of Chahar Province in 1952, a total of 116 governors, acting governors, provincial chairmen and autonomous region chairmen served here over a period of 190 years. The Chahar General's Office was built according to the regulations of the first-rank government office in the Qing Dynasty, and originally had three buildings: the central, eastern and western sections. The overall layout has a running central axis, symmetry on the left and right, with the front court and the rear bedroom, clear priorities and strict regulations. Now only the middle road remains, with a total of four courtyards. On the central axis are the main gate, ceremonial gate, lobby, second hall, and main bedroom at the back, with ear rooms and wing rooms on the left and right.
