Changying is one of Beijing's most famous Hui ethnic groups, and the competition for shabu-shabu restaurants is fierce, with the Changying brothers being one of the best performers. The founder, Xiao Fengying, was originally a taxi driver who founded Shabu Shabu Restaurant just to support his family. Because he is the third in the family and is easy to make friends, he was named "Chang Win Three Brothers". With the support of the government, the three Changying brothers had a very good entrepreneurial situation in the early stage and were well received by local gourmets. After nearly 20 years of development, Changying three brothers have become a star enterprise in Chaoyang District. Own pasture is the killer feature of the three brothers. In order to allow diners to eat tender mutton, the three Changying brothers established their own pasture and cold chain logistics system in Xilin Gol, Inner Mongolia. Compared with the ordinary mutton produced in Dachang County, it has the advantages of not being sour and having less taste. In the choice of small materials, the boss also has his own persistence. For small materials like leek flowers, the three Changying brothers chose to establish a leek flower planting base in Zhangjiakou. In order to strengthen the quality control of small ingredients, the three Changying brothers also established a processing base for small ingredients such as leek flowers, sweet garlic and sesame paste in Yanqing, Beijing. All kinds of shabu-shabu materials arrive at the store on time, and the stability of shabu-shabu production is very high. The dishes of the three Changying brothers are very rich, and almost all the major parts of the mutton are available, and they are cut to order. The best lamb shank is a must-order dish, the performance is relatively good, after cooking, there is a mellow mutton flavor exuding, and it is very chewy, without the slightest smell of mutton, and there is a sweet aftertaste of mutton in the mouth. Many diners will also recommend the lamb brain, which is located at the back of the neck and on both sides of the backbone, the fat is evenly interwoven between the lean meat, there is obvious marbling, the meat is very delicate, melts in the mouth, and the fragrance is three-dimensional and full. The large hand-worn skewers in the store are quite exotic, and the meat is baked just right, and it has a slight pink color, which is very fragrant. Changying store is the old store of Changying three brothers, the store has only one floor, and the decoration is not brilliant, but it is quite popular with the local people, and the meals are basically full. For business considerations, the three Changying brothers set up the head office in Lugang City, Chaoyang North Road, not far from the old store, with a larger area and more atmospheric decoration, which is worthy of consideration by customers who value the environment. However, it is a pity that there are no private rooms in the old store and the main store.
