Wu Fei, a veterinarian in a small town, unexpectedly gains the ability to understand animals. From then on, the big black donkey reveals secrets, the little yellow dog rushes to deliver messages, and even the fish on his dinner table can warn him to avoid scams! Using clues provided by animals and his own veterinary skills, he resolves a sheep disease crisis, rescues injured pets, and helps villagers see through the schemes unfolding around them. From fighting for the local veterinary station to opening his own small clinic, Wu Fei earns people's trust through one challenge after another. Together with his bickering animal companions, he finally turns his once-frustrating life into one filled with confidence and hope.
