The couple operated the business themselves, walking around the streets and carrying baskets to sell. The beef slices they sell are actually beef scalp, heart, tongue, tripe, and beef, and no lungs are used. Pay attention to the selection of ingredients, fine production, and exquisite seasoning. The couple's beef slices are large and thin, glutinous and delicious, spicy and fragrant, tender and stale. It is deeply loved by the masses, and in order to distinguish it from other beef slices, it is called "Couple's Feather slices". After setting up a store, we became more particular about the materials used and the quality improved day by day.
