By the Ming Dynasty, eight mountain strongholds were built along the Badaling Great Wall, where soldiers were stationed. There were legends about every village, stronghold, city, pass, and even stone and spring. The legends handed down from generation to generation, such as "Wangjing Stone", "Liulang Shadow", "Jinniu Cave", "Shifo Temple", "Mu Guiying Dianjiangtai", and "Tanqin Gorge", are still popular. Even the origin of the name "Badaling" has many versions in folk legends.
