Zhongshu Sheng in the context of "Menxia Sheng"

Khanbaliq (Chinese: 汗八里; pinyin: Hánbālǐ; Mongolian: ᠬᠠᠭᠠᠨ ᠪᠠᠯᠭᠠᠰᠤ, Qaɣan balɣasu) or Dadu (Chinese: 元大都; pinyin: Yuán Dàdū; Mongolian: ᠳᠠᠶ᠋ᠢᠳᠤ, Dayidu) was the winter capital of the Mongol-led Yuan dynasty in what is now Beijing, the capital of China today. It was located at the center of modern Beijing. The Secretariat directly administered the Central Region (腹裏) of the Yuan dynasty (comprising present-day Beijing, Hebei, Shandong, Shanxi, and parts of Henan and Inner Mongolia) and dictated policies for the other provinces. As emperors of the Yuan dynasty, Kublai Khan and his successors also claimed supremacy over the entire Mongol Empire following the death of Möngke (Kublai's brother and predecessor) in 1259. Over time the unified empire gradually fragmented into a number of khanates.

Khanbaliq is the direct predecessor to modern Beijing. Several stations of the modern city's subway's Line 10 and Line 13 are named after the gates of Dadu.

Hebei is a province in North China. It is China's sixth-most populous province, with a population of over 75 million people. Shijiazhuang is the capital city. It borders Shanxi to the west, Henan to the south, Shandong and Liaoning to the east, and Inner Mongolia to the north; in addition, Hebei entirely surrounds the direct-administered municipalities of Beijing and Tianjin on land. Its population is 96% Han Chinese, 3% Manchu, 0.8% Hui, and 0.3% Mongol. Varieties of Chinese spoken include Jilu Mandarin, the Beijing dialect of Mandarin, and Jin Chinese.

During the Spring and Autumn and Warring States periods (771–226 BC), the region was ruled by the states of Yan and Zhao. During the Yuan dynasty (1271–1368), the region was called Zhongshu. It was called North Zhili during the Ming dynasty (1368–1644), and simply Zhili during the Qing dynasty (1644–1912). The modern province of Hebei was created in 1928. Five UNESCO World Heritage Sites can be found in the province: the Great Wall of China, Chengde Mountain Resort, Grand Canal, Eastern Qing tombs, and Western Qing tombs. It is also home to five National Famous Historical and Cultural Cities: Handan, Baoding, Chengde, Zhengding and Shanhaiguan.

The Three Departments and Six Ministries (Chinese: 三省六部; pinyin: Sān Shěng Liù Bù) system was the primary administrative structure in imperial China from the Sui dynasty (581–618) to the Yuan dynasty (1271–1368). It was also used by Balhae (698–926) and Goryeo (918–1392) and various other kingdoms in Manchuria, Korea and Vietnam.

The Three Departments were three top-level administrative structures in imperial China. They were the Central Secretariat, responsible for drafting policy, the Chancellery, responsible for reviewing policy and advising the emperor, and the Department of State Affairs, responsible for implementing policy. The former two were loosely joined as the Secretariat-Chancellery during the late Tang dynasty, Song dynasty and in the Korean kingdom of Goryeo.

The government of the Ming dynasty (1368–1644) was modeled after the Mongol-led Yuan dynasty. Over time, the government system changed and adapted to circumstances. The Ming government was traditionally divided into three branches—civil, military and surveillance, with the imperial household and its eunuchs holding a distinct position.

In the beginning, the central civil authorities were led by the Central Secretariat, which oversaw Six Ministries and other less significant institutions. The Chief Military Commission served as the high command of the army, while the Censorate held the highest control authority. The empire was divided into two metropolitan areas and thirteen provinces, each of which was managed by a Branch Secretariat. The lower levels of administration included prefectures and subprefectures, with the lowest level being the counties. There were approximately 1,400 counties in Ming China.

The Yuan dynasty was a Mongol-led imperial Chinese dynasty. During its existence, its territory was divided into the Central Region (腹裏) governed by the Central Secretariat (Zhongshu Sheng) and places under control of various provinces (行省) or Branch Secretariats (行中書省), as well as the region under the Bureau of Buddhist and Tibetan Affairs (Xuanzheng Yuan). In addition, the Yuan emperors held nominal suzerainty over the western Mongol khanates, but in reality none of them were governed by the Yuan dynasty due to the division of the Mongol Empire.

Beizhili, formerly romanized as Pei-chih-li, Pechili, Peichili, etc. and also known as North or Northern Zhili or Chih-li, was a historical province of the Ming dynasty. Its capital was Beijing, from which it is also sometimes known as Beijing or Peking Province. Beizhili mostly covered the area of the Yuan province of Zhongshu—the "Central Administration"—and took its own name—Chinese for "Northern Directly Administered Area"—from Beijing's status as the Ming's national capital following the Yongle Emperor move there from Nanjing, which oversaw Nanzhili or the Southern Directly Administered Area. In 1645, at the beginning of the Qing dynasty, the name of Beizhili was changed to Zhili. Under the Republic and People's Republic of China, it was divided into Hebei and the provincial-level municipalities of Beijing and Tianjin. (Small parts of what was once Beizhili were also ceded to Henan and Shandong.)

The Grand Secretariat, or the Cabinet (Chinese: 內閣; pinyin: Nèigé), was nominally a coordinating agency but de facto the highest institution in the imperial government of the Chinese Ming dynasty. It first took shape after the Hongwu Emperor abolished the office of Chancellor (of the Zhongshu Sheng) in 1380 and gradually evolved into an effective coordinating organ superimposed on the Six Ministries. There were altogether six Grand Secretaries (Chinese: 內閣大學士), though the posts were not always filled. The most senior one was popularly called Senior Grand Secretary (首輔, shǒufǔ). The Grand Secretaries were nominally ranked as mid-level officials, ranked much lower than the Ministers, heads of the Ministries. However, since they screened documents submitted to the emperor from all governmental agencies, and had the power of drafting suggested rescripts for the emperor, generally known as piàonǐ (票擬) or tiáozhǐ (條旨), some senior Grand Secretaries were able to dominate the whole government, acting as de facto Chancellor. The term nèigé itself is now used to refer to the modern cabinet in Chinese.

The Grand Secretariat system was adopted by the Later Lê dynasty and Nguyễn dynasty of Vietnam. It was also adopted by the Qing dynasty of China, but only served as the de jure highest institution in Qing China.
