A waitress serves snacks at a Chuanbeiliangfen restaurant in Nanchong, southwest China's Sichuan Province, Sept. 11, 2017. Li Hua, an inheritor of Chuanbeiliangfen, also called Clear Noodles in Chili Sauce, a provincial intangible cultural heritage in Sichuan, became attached with this special snack since she was 18 years old. Now Chuanbeiliangfen has become a famous brand. Thanks to Lanzhou-Chongqing railway, express highways and the Internet, Li has expanded her business to many provinces and cities in China. She hopes that her business would go abroad in the future. (Xinhua/Liu Chan)
