The ancients thought that fish and sheep were the freshest foods in the world, and it would be fresher if they were cooked together, so there was a famous dish called "sheep hide fish". It is unknown who invented this dish, but it has something to do with the legendary character "Peng Zu". This man was born in the Xia Dynasty. Some people say that he lived to be 767 years old, while others say that he lived to be over 800 years old. In ancient times, Peng Zu was used as a symbol of longevity. Peng Zu's good spoon was dedicated to Yao and was praised by Yao. It is estimated that Peng Zu can not only cook soup, but also cook. We might as well think that "hiding fish from sheep" was invented by Peng Zu or his descendants.

Xuzhou was called Pengcheng and Pengcheng Country in ancient times, which was sealed by Emperor Yao when Pengzu was here, so this dish has a lot to do with Pengzu. Peng Zu has a research on soup. Soup pays attention to a fresh word, so he also pays attention to "fresh" in dishes. He cooks sheep and fish together and thinks that it is the freshest and freshest. The ancient Chinese character "Xian" also comes from the famous dish "sheep hide fish", which is also a highlight of Peng Zu's food culture.
