The lotus-collecting girl impressed the dragon prince with her beautiful song, then they got married. Unexpectedly, the queen took the dragon prince to repair the palace for herself. The lotus-collecting girl knitted a coat with a hundred bird's feathers according to the dragon prince's request. Can she save the dragon prince? The version on which this book is retold is the "Dragon Lady" in the "Fairy Tale of Lin Lan", which is not a "pure" story of the "Coat with a hundred bird's feathers" type, but a hybrid of two types of stories, "The Music Man and the Dragon King" and "Coat with a hundred bird's feathers", which have been retold with a modern twist to give them the wisdom and power of a new era.
