Once upon a time, Su Yao had a cat, but the cat grew bigger and bigger, and the more it ate, the fatter it became. Later, Su Yao couldn't afford it anymore, so he dragged the cat's tail and knocked on the door of Prince Xuan's Mansion.
Su Yao: "How about raising cats together?"
King Xuan: "Okay."
Between men, there is a lot of knowledge in raising cats. (Adapted from Mr. Qian Zhongshu's siege)
