There is a group of tombs on the top of Mount Muri in Qungjie County, the former capital of the Tobu Kingdom. These are the tombs of the kings and queens of the Tobu Kingdom. The tombs are protected by the mountains in back and guarded by stone lions erected on the mountain slope. There are steles among the tombs to honor the dead, suggesting that by that time the Tibetans had developed a sophisticated system for burying their dead. One stele in particular is carved with floating clouds and the four corners of the stele are turned up toward the sky.
