Where is Zijingguan? What is its position in history?

Zijingguan is one of the passes of the Great Wall. It is located on Amethyst Mountain, 40km west of Yixian County, Hebei Province, China. It is one of the main roads for Hebei Plain to enter Taihang Mountain.

Zijingguan was built in the Warring States period. It was tamped with mud and stones in the Han Dynasty, and then expanded and repaired by generations. In the early years of Hongwu in Ming Dynasty, it was based on stone strips, covered with bricks and filled with lime and gravel. After Ming Chengzu moved his capital to Beiping, he built the Chengguan. During the years of Zheng Tong, Jingtai, Hongzhi, Jiajing, Wanli and Chongzhen, Guancheng was rebuilt and expanded, castles and passes were added, and Panshan Road was dug, which made Zijingguan form a relatively complete defense system.

Since the Jin and Yuan Dynasties, they have all been named after Zijingguan. Large-scale reconstruction and new construction in the early Ming Dynasty is one of the important passes of the Inner Great Wall, which is located between Juyong Pass and Daoma Pass, and the two passes are collectively called Inner Three Passes.

Because of the dangerous terrain, it has been one of the important portals of the North China Plain since ancient times and a battleground for several military strategists.

There have been 140 wars in Zijingguan in history, the most famous of which was in the first year of Jin Zhenyou (A.D. 12 13), when Genghis Khan attacked Juyongguan, he divided his troops and defeated the nomads from Zijingguan, and successfully attacked Juyongguan from the inside. In the 14th year of Ming Dynasty (A.D. 1449), after the change of civil engineering, the Mongolian Walla department broke through the Zijing Pass and advanced on Beijing.
