Seven-year-old girl Xiaohe lives in the small town of Qingzhu halfway up the mountain. One evening, she accidentally picks up a small breathing cloud "Tuantuan" and thus discovers the "Cloud Post Office" hidden on the top of the cloud. Here are stored the wish letters of all the tiny creatures in the world - the grass wants to bask in the sun, the fish wants to see the stars, the flowers want to be hugged by butterflies... However, the fog in the valley blocks the way to the Moon Warehouse, and the wish letters have been backlogged for a long time. Xiaohe put on a cloud hat and a cloud backpack, becoming the only human little postman in the world, and embarked on a gentle and healing journey of delivering letters.
Intention: A small wish deserves to be fulfilled with gentleness. Kindness means leaning down to see the neglected corners of the world.
