In Xi 'an, old Jia Fan has almost become synonymous with bacon. Bacon originated in the Warring States period and was called "cold meat" at that time. After being passed down and evolved from generation to generation, it became today's Qin-flavored bacon. Bacon has a history of nearly a hundred years, which was initiated by hawker Fan. Because of its fine selection of materials, complete seasoning, great firepower and long-term stew, its color is rosy, soft and mellow, and it will remain unchanged for a long time. Consumers have the praise that "fat meat is not greasy after eating, lean meat is full of oil and no residue, and the meat is rotten and toothless, leaving fragrance for a long time after eating". In recent years, the strict implementation of operating procedures in the production process has increased the proportion and flavor of lean meat, making it more fragrant and deeply loved by consumers. It has been rated as a famous snack in provinces and cities for many times. 1989 won high praise for its unique flavor and won the "Golden Top Award" for quality products of the Ministry of Commerce. Eat it with freshly baked Baiji steamed buns, which are fragrant and crisp, with endless aftertaste.
