Introduction to Dengzhan's Nest: Dengzhan's Nest was one of the base camps of Wang Xiaobo and Li Shun's uprising in the Northern Song Dynasty. The remains of the stone foundations of lamp poles from that time still remain. According to legend, there is an immortal "holy lamp" in Dengzhan's Nest, which illuminates the barracks of the Peasant Uprising Army brightly day and night, hence the name Dengzhan's Nest.
