Jianfen, or fried bite-sized noodles, is a local snack of Jilin city. Made from sweet potato flour, the snack originated in the city and was soon introduced to Changchun. For quite a while, it was available in only Jilin and Changchun. Later on, it appeared in some cities in Liaoning province but had a different name, fried stew. (Stir-fried stew started in Dalian and is called Dalian stir-fried stew. It is similar to stir-fried noodles). However, Jilin's Jianfen is more popular than others due to their long history and good flavor.
