Xiaomian is a traditional numbingly hot noodle soup from Chongqing, a southwestern municipality of China. For many people who live in this city, the noodles are an integral part of their diet.

Gao Wei, a 37-year-old woman, opened a noodle restaurant with her husband in the city more than a decade ago. In addition to running the restaurant, she has taught many people how to making xiaomian making since 2005. Now, the learners have opened more than 1,000 xiaomian restaurants in other parts of China and other parts of the world. They are carrying forward the brand of Chongqing xiaomian, Gao said.

But many years ago, Gao was just a migrant laborer who moved to this city with her husband with only a few chairs and tables to start up the business.

After 20 years, Gao's restaurant attracts a host of enthusiasts of Chongqing xiaomian. "I want our restaurant to keep going for centuries," Gao said.
