Which country did Zhangbei belong to in ancient times?

During the Shang and Zhou Dynasties, there was a nomadic tribe in the vast area of northern China, including this county, which was called "Ghost Party" at that time.

During the Spring and Autumn Period, this county was a country without a final country. The good end of the family, entered the week at the beginning of the week, was defeated by the doctors of the State of Jin, and was finally destroyed by Jin.

At the end of the Spring and Autumn Period, the county was the sphere of influence of nomadic tribes in East Lake in Northeast China. In 279 BC, Yan attacked the East Lake, forcing back thousands of miles, and the county transferred to Shanggu County. By the end of the Warring States period, it had entered the northern territory of Qin, Zhao and Yan. In the early Han Dynasty, Emperor Liu Bang failed in the Northern Expedition, so he had to personally levy the Huns and divide the territory. After that, the county was changed to Xiongnu, and later returned to the Han Dynasty, where Wu Huan lived.

During the Ming and Qing Dynasties, immigrants moved to the real border, and the historical development of this area has undergone tremendous changes. During the reign of Shunzhi in Qing Dynasty, the county was an official pasture and an official wasteland. In the 14th year of Kangxi (1675), most of the county belonged to the nomadic land of Chahar Yellow Banner. In the second year of Yongzheng (1724), Zhangjiakou Governor's Hall was established and gradually recovered. In the early years of the Republic of China (19 13), the hall was changed to a county, the territory was moved, and the division should be curved, so it was called the first county on Bashang, and it was named "Zhangbei" because it was located in the north of Zhangjiakou.
