Belonging to Sichuan cuisine, Sichuan Han specialty snacks are made from beef scalp, beef heart, beef tongue, tripe and beef. They pay attention to the selection of ingredients, fine production and exquisite seasoning. Husband and wife's beef slices are large and thin, glutinous and delicious, spicy and fragrant, tender and stale.

In the late Qing Dynasty, there were many vendors selling cold beef slices in the streets and alleys of Chengdu carrying burdens and baskets. Using low-cost beef offal scraps, finely processed and stewed, then cut into slices and served with soy sauce, red oil, chili, pepper noodles, sesame noodles, etc. It has a unique flavor, low price and good quality, and is especially popular with rickshaws, A favorite food of porters and poor students.

In the 1930s, there was a couple who ran a stall in Chengdu, Sichuan. The boy was Guo Chaohua and the girl was Zhang Tianzheng. Because of their exquisite preparation of cold beef lung slices, they were golden-red in color, spicy and fragrant, and had a unique flavor. In addition, the couple cooperated tacitly and harmoniously, one produced and the other sold, and the small business was booming. Customers gathered for a while, and demand exceeded supply.

After the public-private partnership, the Guo couple merged into the Chengdu Catering Company. The company felt that the word "waste slices" did not sound very good, so it changed the word "waste" to "lung" and registered "couple's slices". ”, this is the origin of the name of this famous dish in Chengdu. This dish contains beef tongue, beef heart, beef tripe, and beef scalp. Later, beef was also added, but there was no beef lung. However, it was also called "lung slices". It was just a coincidence that it did not live up to its name. .
