Beijing Yueshengzhai was founded in the 30th year of Emperor Qianlong's reign in the Qing Dynasty (1765) by Ma Qingrui. Because the store was located on the south side of the moon-shaped wall road west of the Qianmen Arrow Tower in Beijing and opened during the Hui Muslim month of Ramadan, it was named "Yueshengzhai", which means prosperity every month. Yueshengzhai was famous for its braised mutton and roasted mutton, and has a high status in the halal food industry in Beijing. Yueshengzhai's cooked meat production process is divided into two categories: sauce making and roasting. On the basis of absorbing the palace sauce meat technology and folk traditional characteristics, it also introduces the health theory of traditional Chinese medicine and related medical knowledge. More than 20 spices that can be used for seasoning and medicinal value are used in the production. The meat is not only more delicious, but also has the effect of nourishing and maintaining health. The production process of Yueshengzhai's braised mutton in sauce is relatively complicated, especially the heat. In addition to the selection of materials, formula and unique soup mixing technology, there are about 20 processes such as material inspection, material selection, soup adjustment, and cooking. Throughout the production process, Yueshengzhai always adheres to the principle of "selecting excellent ingredients, both fat and lean, never saving trouble; exquisite recipes, good color and taste, never saving money; fine production, sauce and stew, never saving labor". The dishes are fat but not greasy, lean but not woody, crispy on the outside and tender on the inside, crispy and refreshing, not smelly or greasy, moderately salty, fragrant and delicious, with a long aftertaste, integrating the aroma of meat, sauce, medicine and oil. Yueshengzhai's cooked meat was once famous as a palace food in history. There are many records of this in the historical books of the Qing Dynasty, and many celebrities have written inscriptions for it. In this sense, Yueshengzhai's beef and mutton products carry certain cultural connotations and have certain research value in the traditional Chinese food culture. Today, Yueshengzhai undertakes the task of supplying halal meat products needed for daily life for the people who believe in Islam in Beijing, and is also responsible for providing special halal meat for large domestic and international conferences. With the changes in society, Yueshengzhai has encountered many problems in its operations, especially factors such as unhealthy competition in the market, which have caused difficulties in the development of this old brand. The inheritance of Yueshengzhai's braised beef and mutton making skills is currently in serious crisis and needs urgent protection.
