Introduction to Zangdao Cave: Cross the Guanfo Road to Zangdao Cave, surrounded by greenery and beautiful scenery. According to legend, this is where Zhang Kun, the general of the Great Xia Kingdom, obtained the golden sword. The stalactites in the cave have strange shapes. One stalactite resembles an empty scabbard piercing into the gorge. Although the golden knife is long gone, the scabbard still remains in the cave. Standing on the viewing platform and looking around, it looks like a golden knife hanging high on the top of the cave, with its light shining and the cold air coming.
