Introduction to Treasure Hunting in the Rift Valley: According to folk rumors, King Xuyan hid sacrificial vessels in Xiaojianshan, Luqiao, and gold and silver jewelry in the Fushan Rift Valley. For more than a thousand years, people have rushed into the valley to hunt for treasure, but the entrance to the rift valley cannot be found. The cave is narrow, dark, moist, and unfathomable. No one who goes in can steal the treasure.
