The document discusses the Korean folklore tradition of Nae-Na-mu (Tree of My Own). In the tradition, when a new baby is born in a family, they would plant a tree on either a nearby mountain or field on the holiday of Han-sik, which occurs 105 days after Dong-ji (winter solstice). If a baby boy was born, a pine tree would be planted which could later be used for a coffin, and if a baby girl, a royal foxglove tree would be planted that could later be used to make a drawer for her marriage. The planting of the tree was meant as a symbol of the child's life and to wish for their prosperity.
