Introduction to the Marnyi stones along the road: Marnyi Stone is a traditional Tibetan folk art. Most of them are engraved with six-character mantras, wisdom eyes, statues of gods, and various auspicious patterns, in order to dispel evil and seek blessings. Mani stones can be formed into Mani piles and piled up in mountains, intersections, lakesides and riversides. This colorful mani pile was discovered by the lake on the way to Xiagui.
