The misleading and jealous story of the eight sisters of Princess September. This story obviously has certain allegorical and realistic educational significance for children.

The Princess and the Nightingale in September is the only children's book written by Mao Mu, and it is also one of the series of "Great Writers Write for Children". The account of jealousy in the book is wonderful. Princess September was surrounded by hints and argots because of the jealousy of her sisters. Readers on the side will be anxious about her, and they can also well identify the jealousy and the scenes hinted by others' jealousy, so as to have a better understanding of human nature.
