As early as the pre-Qin period, Xi'an had a food tradition of "Qin people are good at treating sheep and Qin people are good at using soup". In modern Chinese history, the Sun family participated in many important historical events, such as Premier Zhou's banquet for Vietnamese and British guests, Chiang Kai-shek and Song Chuyu's visits to the mainland during the Xi'an Incident, and so on. In 2008, mutton soup steamed buns and Qinqiang were shortlisted as the "Top Ten Cultural Symbols of Shaanxi Province", and the Sun family, as the representative of mutton soup steamed buns, made great contributions. The Sun family's mutton soup steamed buns are made of fine materials, fine production, and complete nutrition. In particular, the unique use of sixteen selected seasonings when boiling meat and simmering the meat makes it "heavy ingredients and strong flavor", unique and unfailing for a hundred years. The process of cooking meat, soup, and steamed buns into a bowl of mutton soup is very delicate and natural. "The diners break the steamed buns, the chefs cook, the steamed buns determine the soup, the soup determines the time, the time determines the appearance, the shape, the taste, and the fragrance", this is the secret in the hearts and hands of the chefs of the Sun family. It is for this reason that Lao Sun's mutton soup steamed bun has won the national "Golden Tripod Award", "Xiaohua Famous Snack", "International Famous Snack" and other honors. In the 111-year history of development, Lao Sun's in Xi'an has inherited innovation and accumulated profound experience, and established the golden signboard of mutton soup steamed bun and the classic halal dishes series.
