The origin of the story: It is said that Peng Zu, the youngest son in Xuzhou history more than 4,000 years ago, was the first person to create fish and cook with sheep for thousands of years. His youngest son, Xiding, likes fishing and touching shrimps. Peng Zu was afraid of drowning, so he got angry. One day, Xiding caught a fish and prepared to cook for his mother. She is stewing mutton at Qiaojia. While Peng Zu was away, her mother cut the mutton and hid the fish. She stewed it with mutton until the fish was cooked, and then took it out with Xiding. When Peng Zu went home to eat mutton, he found a strange smell and asked him why. His wife explained that if he cooked it in the same way, Peng Zu was delicious. From then on, inspired by the success of fish and sheep, Peng Zu created an extraordinary famous dish-sheep-hidden fish, which was honored as "a hundred dishes". Unfortunately, it was later lost, and Yangcheng people named after sheep even gave birth to a "hundred fold Sect".
