Jiang Li inherits a zoo on the verge of bankruptcy from her grandmother, along with a secret: only she can hear the animals talk. She wants to walk away and start a new life, but the sincere affection of a group of furry friends makes her stay. She treats a lion's teeth, saves an old elephant's leg, accompanies penguins as they line up, and listens to alpacas complain. The animals remember what she was like as a child and are willing to help protect her, just as they promised her grandmother. She personally works to bring the rundown zoo back to life, and the animals voluntarily join the workforce to help her. This is a heartwarming story about protection, family, and the mutual devotion between humans and animals.
