In 1930s, Chengdu native Guo Chaohua and his wife made and sold cold lung tablets together. The couple personally operated, walked the streets and sold baskets. Because the leftover materials from beef shops are used as ingredients, they are cheap and delicious, and they are very popular. People call this cold beef offal "husband and wife leftovers". Because the word "waste" is not pleasant to hear, and there are beef lung slices in the ingredients, the homonym "lung" of "waste" is taken and renamed as "husband and wife lung slices" Later, they found that the beef lungs tasted bad, so they cancelled them.
1933, Mr. and Mrs. Guo opened a shop for sale near Chengdu Banbian Bridge (now on the right side of the back door of People's Park). The name of the store was officially named "Husband and Wife Lung Tablet", and the plaque was inscribed by calligrapher Zhao Yunyu. After several changes, the store moved to Fuyin West Street, a downtown street, expanding its business scale and adding beef noodles. Diners can not only taste lung slices, but also eat pasta to satisfy their hunger.
After the founding of New China, during the period of public-private partnership, the couple's lung slice shop, like other traditional restaurants, was merged into state-owned units. After several generations of efforts, the couple's lung slices have become a famous cooked food takeaway shop at home and abroad.
