Lazy people expect pie from the sky. Ji Lou is a lazy person.
Cats love to eat fish. Ji Lou is a cat.
Now, a "big fish" fell from the sky in front of Lazy Mao Jilou. It looked rich and plump. He also said that if he followed him, he could eat well and drink spicy food. To be precise, this is what this handsome-looking fish said in a certain snack street: "Lou, I want to keep you."
Thus, the lazy cat Ji Lou officially began his days of being kept by fish.
