This is the site of the Great Wall of the Ming Dynasty in Yanchangbao Town, Dingbian County, which is adjacent to the highway on one side.

Located in Yanchangbao Town, Dingbian County, the site of the Great Wall of the Ming Dynasty is adjacent to the highway on one side and immersed in a large area of water on the other side, forming a "dike" for retaining water. It is said that the water is drained from a local sewage treatment plant. Because of the low-lying terrain, a large area of water is formed, which directly threatens the Great Wall site and highway safety.
