Spicy hot pot originated in Chongqing. At that time, the workers who carried the load on the Jialing River bought the internal organs of the buffalo, washed them, cut the liver and stomach into small pieces, put a stove on the head of the load, and put an ocean iron basin on it. The iron basin became a multi-grid, which contained spicy and salty lo-fi and sold it to the dock workers. When guests visit, everyone will be recognized as one, and they will be burned. In the 23 rd year of the Republic of China, a large-scale spicy restaurant appeared in Chongqing, but the iron basin was replaced by a small copper pot, and the guests prepared their own marinade to dip in.
