According to legend, in the 1930s, near Shaocheng, Chengdu, there was a man named Guo Chaohua who, together with his wife, made a living by making and selling cold beef and lung slices. The couple personally operated and walked around the streets, carrying baskets and selling them. Because of their fine production and unique flavor, the cold lung slices they operate are deeply loved by people and are called "husband and wife lung slices" After the establishment of the store, we pay more attention to the materials, replacing the original single lung with beef, heart, tongue, belly and scalp, and the quality is improving day by day. Although this dish is a snack, it has long been included in the list of famous dishes because of its fine cooking, fine ingredients and delicious taste.
