Because the couple's lung slices were made of some cows in the water, people liked to call them "husband and wife's waste slices" at that time, and later thought that the waste words were not good, so they changed them into lungs. Later, in order to make business more prosperous and take care of customers' tastes, beef and mutton offal gradually evolved to replace beef lungs, but no matter how the ingredients changed, the name of husband and wife lung slices has been used to this day.

Why is the husband-and-wife lung piece called the husband-and-wife lung piece?

The appearance of husband-and-wife lung slices was in the 1930s, which was ignited by a couple named Guo Chaohua and Zhang Tianzheng. The cold lung slices they made were exquisite in craftsmanship and delicious in color, flavor and taste. The appearance is bright and ruddy, and the taste is spicy and delicious, which is very attractive.

Usually, the practice of cold-mixed lung slices is similar, which is made of some beef offal as raw materials, especially beef lung slices. After simple marinating, add red oil, soy sauce and pepper, and stir.

In fact, lung slices appeared in the streets and lanes of Chengdu as early as the end of the Qing Dynasty. At that time, you could often see small vendors selling lung slices on the street, and most of them were carrying pole or carrying bamboo baskets with their own cold lung slices.
