In the Nianbaoyuze legend, a hunter rescues a small white snake from a black eagle. The snake is the mountain deity’s son. The hunter later kills a demon ox occupying the sacred mountain; in gratitude, the deity gives him a daughter in marriage. Their three sons become the ancestors of the Three Golok peoples in the story.
The national heritage catalogue presents the episode as part of a series about the origin and development of the Three Golok groups. Nianbaoyuze—also called Golok Mountain in the record—stands in the tale as an ancestral spirit and protector.
