Lin Yi is an ordinary zoo intern. His daily job is to shovel poop and feed him. His colleagues mocked him as a waste, his supervisor wanted to fire him, and even the monkeys in the garden dared to steal his bananas. Until one day, an out-of-control tiger rushed into the park - everyone screamed and ran for their lives. Only Lin Yi yawned, walked over and patted the tiger on the head: "Don't make trouble, go back to sleep." The tiger instantly behaved like a cat, lying down and rolling around. The whole place was petrified. From then on, Lin Yi's daily life in the zoo became: What kind of beast will come to me today to recognize his family? How will the person who looks down on me get slapped in the face tomorrow?
