Chen Ahpo, who gathers herbs deep in the mountains, met a little girl named He Dou who was lost alone by the mountain stream. The child was born with great strength, but was always afraid that her clumsy hands and feet would cause trouble. Ahpo held her hand, teaching her step by step to restrain her strength and cherish this special gift. He Dou also gradually grew from her initial timidity into a little guardian capable of moving stones to clear paths and protecting the villagers in the mountains, finding her own home in the great mountains.
