On the first day of summer vacation, 10-year-old Banxia received a mysterious gift from her grandma—an ancient copper key and a note saying "Keep the key."
The small old wooden door covered in ivy in the backyard perfectly matches this copper key, opening it into a fairy tale world filled with magical creatures and exotic plants.
What is the connection between the confusing fairy tale world and this bronze key?
Intention: Open the summer in your heart
