Manidui introduction:The Manidui in Lamu Yangcuo Lake has its special significance. It is called "Bengdeng" in Tibetan. It plays a complementary role with the mountain opposite. . The platform on the mountain opposite is a place dedicated to sky burial for monks in the temple after their death. During the sky burial, the monks will go to the Mani pile on this small island to perform the ritual of chanting sutras and salvation for the deceased. Therefore, generally no one is allowed to go to the island.
