Niugan Mafei, literally means bull's liver and horse's lung. It is 5 kilometers from Qingtan Shoal on the north bank in Xiling Gorge. From a cliff half way up the mountain suspended a lump of reddish brown shale in the east, which is shaped like a bull's liver, and a dark brown rock in the west resembling a horse's lung. Both are strikingly true to life. Hence the name "Bull's Liver and Horse's Lung".
