In July, 11-year-old Lin Xiaoyu received a special summer vacation assignment - to send a letter to the mysterious "Rainbow Town Time Post Office".
With the strange compass left behind by her grandfather, Xiao Yu, accompanied by her partner Su Xiaoxiao, embarked on the road to find the seven testing places.
From the dense forest of ancient trees to the crystal cave; from the Bridge of Courage to the Fountain of Patience; from the Valley of Sharing to the Lake of Memory, and finally the last stop - Rainbow Town. Each place gives them a magical map fragment, and also gives the two friends a precious character.
Along the way, they met forest guardians, geologists, bridge challengers, mountain elders, sharing valley owners, memory painters... Each guardian taught them in a unique way to listen to the secret words of nature, discover hidden beauty, face their inner fears, understand the depth of time, experience the joy of giving, cherish the memory of life, and embrace bright hope.
When the seven maps merge into one, the door to Rainbow Town will open.
The white-haired postman Mr. Zhong finally received the letter and revealed the deepest secret of the journey.
——The most important thing is never the letter itself, but how the sender grows into a better version of himself on the road.
Purpose: Growing on the journey
