Xiaoyue's mother was ill in hospital, and her father took her and her four-year-old sister Xiaomei to live in the countryside. They all felt very strange about the environment there, and found a lot of interesting things. They met a lot of elves, they came to their environment, saw a lot of strange things in their world, and became friends with a big fat chinchilla. Chinchillas and elves use their magical powers to bring Xiaoyue and her sister a lot of magical landscapes, which are eye-opening to them. Sister Xiaomei often misses her sick mother and asks her sister to take her to see her mother, but Xiaoyue refuses. Xiaomei unexpectedly went there by herself, only to get lost on the way, so Xiaoyue had to look for her chinchilla and elf friends to help.
