Zhangjiakou City, Hebei Province, located in the northwest of Hebei Province, China, is the north gate of Beijing and a battleground for military strategists in history. The birthplace of Zhangjiakou is now located in Zhangjiakou Bunker, qiaoxi district, and its development here is a historical witness of Zhangjiakou's gradual prosperity. The origin of Zhangjiakou's name is also closely related to it. Zhangjiakou Bunker (also known as Xiabao) belonged to Fu Xuan Town, the capital of Beijing, in the Ming Dynasty, and it was a well-protected place. In the fourth year of Xuande (AD 1429), Zhang ordered to build a castle called Zhangjiabao. Zhangjiabao is three feet high and thirteen steps square. There is a gate in the southeast, which is called "Yongzhen Gate" in the east and "Chengen Gate" in the south. In the eighth year of Jiajing (A.D. 1529), Zhang zhen, a garrison, opened a small gate on the wall of the North City, which was called the "Small North Gate". Because the city gate is as small as a mouth, it was built in Zhang zhen, so it is called "Zhangjiakou".
