"Mianmian Mountain City" is a characteristic pasta chain brand independently founded by Beijing Dingnuo Century (hereinafter referred to as Dingnuo) Investment Management Co., Ltd., aiming at spreading pasta culture and promoting the growth of China catering brands. Mr Sun Tao, the technical director of the brand, is a small heirloom in Chongqing. His great-grandfather, grandfather and father all sold noodles in Shapingba, Chongqing, and won the favor and praise of past diners with their ancestral crafts. Mr. Sun Tao learned to cook at the age of 15, and vowed to carry forward the noodle recipes and techniques of his ancestors. At the age of 20, he went to Beijing to look for opportunities to establish a brand chain. It's been 20 years. Years of accumulation have given him a deeper understanding of brand development and market-oriented operation. In recent years, Mr. Sun has traveled all over Sichuan and Chongqing, visiting famous teachers, discussing the production technology of dried noodles, constantly improving the ancestral formula of dried noodles, and finally developing the product series of "Noodles Say Mountain City", which laid a technical foundation for the development of brand and chain of dried noodles.
