The Chaotian pot originated from the folk morning market during the Qianlong period of the Qing Dynasty and is said to be related to Zheng Banqiao. When Zheng Banqiao was in charge of Weifang, he was very concerned about the suffering of the people. In a certain year of the twelfth lunar month, he went to the market to understand the people's feelings. When the farmers in Jixian County were unable to eat hot meals, some people set up a large iron pot in the market, cooking hot dishes for passers-by, cooking pigs in the pot, meatballs. , dried tofu, etc. The soup is boiled and the meat is rotten. The customer sits on the pot. The master chef puts on the hot soup, adds some parsley and soy sauce, and has a thin noodle cake. It is free to use for himself. Because the pot has no lid, people call it "Chaotian pot".
