Bai Xia's sweetheart's magic wand, Princess Balala, is very expensive because it is suitable for children and girls. Bai is a little fairy in the animated film "The Castle of the Little Fairy in Balala" produced by Guangzhou Culture Communication Co., Ltd. She loves music and made a contract with Ruby in the story, but her personality is very cold, especially she hates Xia's childish problems, so that Yan Hexia dances behind her because she remembers all the movements. Although she looks cold on the surface, she is very cold inside.
