Introduction to Nianbao Dadan: Nianbao Dadan is located in the north of Nianbao Yuze, covering an area of ​​36 square kilometers. Datan is rich in water and grass all year round, with cattle and sheep everywhere, and shepherds have lived here for generations. In the south of Nianbao Datan, there is a huge ashlar stone, 120 cubic meters, which the Tibetan people call "Paweng's jade" and considered to be the North Gate God of Nianbao Yuze. What's even more strange is that the boulder will tightly absorb the coins thrown at the ashlar on its surface.
