A mother bear and a mother rabbit went up the mountain to dig ginseng, but on the journey the mother bear killed the mother rabbit. The little rabbit buried hated in his heart. To take revenge, the little rabbit killed the little bear and continued to chase after the mother bear. Running away from the rabbit, the mother bear asked help from the shepherd, the horse herder and so on. With their help, the mother bear hid anywhere she could. Finally, she hid inside the nostril of a wild yak, and out of rage, the wild yak killed the mother bear. Still, the little rabbit had not released his hatred, so he killed the wild yak, too.
