Abstract: As one of the subtypes of “ Swan Maiden, the story type of  Returning Treasures Twice'takes the “getting the treasure and returning the treasure and getting the treasure and returning the token'as the core of the narrative. Prince State, Princess state and Bathing Lake are the three main placeswhere the story takes place. In the analogy of different texts , the six “nodes”of this type of story are sor-ted out: the sacred characters give treasure or give hints , take treasure and leave the princess , the princeleaves treasure and send troops , the princess is injured and takes treasure to leave , the princess returns tothe country and the prince seeks wife. In the specific story, these nodes are interrelated. If a node chan-ges, it will inevitably cause the chain changes in the subsequent story. They are easy to identify and sta-ble parts in the story. The existence of story nodes, on the one hand, defines the general boundary of thestory , and ensures the whole logic of the story consistent; on the other hand, it also provides a lot of freespace for storytellers to play on and between nodes, which guarantees the possibility of story free narration.
