Ten-year-old girl Lin Duoduo discovered the Yunduo Post Office hidden in the canopy of her old locust tree after a rain. The post office is home to cute little cloud elves such as the Marshmallow Elf and the Evening Breeze Elf. They are responsible for collecting letters of children's wishes that they are too shy to express. However, the naughty evening breeze often blows away the letters, making it difficult for the elves to complete the delivery alone.
Duoduo, who has a pure childlike heart and can see elves, has become a little human messenger, carrying a light cloud mailbag on her back to deliver messages everywhere: helping the troubled children convey the message of reconciliation, sending the children's longing for their relatives far away, and delivering the desire for courage to the heart of the little master. While delivering letters, she will encounter minor troubles such as lost letters and disappearing clouds, and she resolves them one by one with the company of her elf companions.
During the gentle delivery journeys, the introverted and timid Duoduo gradually became cheerful and brave. The story uses childlike images such as the summer evening breeze, locust trees, and starry sky to tell the story of children's friendship, longing, and growth, telling readers that every sincere little wish will eventually be received gently.
Purpose: To convey the preciousness of kindness and empathy through the fantasy experience of children sending letters, to show that children gain and grow through companionship and dedication, and to maintain their childlike innocence.
