Introduction to the water burial platform: In Basongcuo Lake, there is a water burial platform. Water burial is a lower-level funeral ceremony for Tibetans. There are many prayer flags next to the water burial platform. It is said that this place is the "heart of the holy lake". Tibetans only need to pray devoutly and then gently place the hada, which represents good luck and good luck, on the lake, and the hada will sink to the bottom of the valley, indicating that the gods have accepted the Tibetan people's gifts.
