Next to the road leading to the slate is a place where white animals haunt. This place, called Yuyin River, rarely receives sunlight, and is suitable for animals such as white golden monkey, white bear, white snake, white turtle, white crow and white owl. The legend of the white snake aroused people's interest, and people rushed from all over the world to have a look. It is said that white animals can only live in the Arctic, so many animals change ancestors in Shennongjia, which cannot be explained by climate alone. Therefore, albinism of animals in Shennongjia has become an unsolved mystery in science.
