The origin of the couple's lung slices ranges from "husband and wife scraps" to "husband and wife lung slices"-the little-known origin of the couple's lung slices is well known to Sichuanese and was founded by Guo Chaohua and Zhang Tianzheng. After the public-private partnership, Guo and his wife merged into Chengdu Catering Company, and the company registered the "Couple" brand trademark for "Couple Lung Tablets". Through the efforts of several generations of the company, the workmanship and formula of the husband and wife lung slices have been continuously improved. The husband and wife lung slices have become one of the 23 Chinese time-honored brands of Chengdu Catering Company, the largest catering enterprise in Sichuan, and have successively won Chengdu famous snacks, Chinese time-honored brands, Chinese famous snacks and Chinese famous snacks. But this is only the approximate source of husband and wife's lung films. If it's not old Chengdu, it's really not detailed. As we all know, "husband and wife lung slices" were originally called "husband and wife lung slices" but "husband and wife waste slices". The historical origin of the couple's lung slices is little known. It is said that near Chengdu, there is a place where ethnic minorities live in Chengdu, especially many Hui people. Because these ethnic minorities believe in Islam or their own customs, they don't eat pork, and beef and mutton are the bulk meat consumed there. Moreover, they usually only eat beef and mutton, and generally discard their internal organs. Every morning, after chanting by a religious Islamic butcher (we in Sichuan call him "the knife maker"), the cattle are slaughtered and divided, and the meat is sent to the market for sale. The cleaned internal organs were abandoned in a corner of the slaughterhouse and piled high. At that time, there was a young couple, the man named Guo Chaohua and the woman named Zhang Tianzheng. When they saw that all these abandoned internal organs were thrown away, they felt that it was a pity that the young couple had nothing to do anyway and were addicted to their livelihood. So they went to the slaughterhouse early in the morning, rummaged through piles of internal organs, took some useful things home, carefully took them out and cooked them in a pot. After several experiments, they mastered the just right temperature. Then carefully cut, pick, cut, cut, and process with a knife. It really makes the tripe white and tender as paper, the tongue red as birch, the scalp transparent and slightly yellow, and it is accompanied by the seasonings carefully matched by the husband and wife, red oil, pepper, sesame oil, monosodium glutamate, superior soy sauce and fresh celery. Therefore, the "lung slices" are red and bright in color and soft and waxy in taste. At that time, where the poor people lived in Chengdu, the cold beef offal of the Guo couple, because of its low price and delicious taste, was not only welcomed by the poor who wanted to eat meat, but also sought after by the citizens who loved its delicious food, and soon became famous. Because its raw materials are picked up from abandoned internal organs and cut into thin slices during processing, it is called "waste slices", and because both husband and wife go into battle together, the word husband and wife is added in front. Later, this dish became more and more famous. After the public-private partnership, Guo and his wife merged into Chengdu Catering Company. The company felt that the word "waste" was not very pleasant to hear, so it changed the word "waste" into the word "lung" and registered "husband and wife lung tablets". This is the origin of the name of Chengdu. This dish has beef tongue, beef heart, beef belly and beef scalp. Later, beef was added, but there was no bovine lung, so it was called "lung slice". Mr. Chongyang, Chairman of Chengdu Catering Company in Sichuan Province (executive director of China Cuisine Association, director of National Institute of Functional Technical Appraisal, vice president of Sichuan Cuisine Association, president of Chengdu Cuisine Association, and a famous Sichuan cuisine theorist) wrote "Husband and wife lung slice shop, a time-honored Chinese brand" in the book "Ode to Sichuan Cuisine", and he devoted half his life to it. Husband and wife have been married for 60 years, and now they have developed more elegantly. Taste for Shu Ren, love all over the world. There is a saying: lung slices are not lungs, they taste delicious, spicy and delicious; Husband and wife get along well, have harmonious tastes and love each other forever. Beautiful couple, quick lungs. "So, this is the reason why" husband and wife lung slices "have no lungs. This is the origin of the couple's lung slices.
