Snail noodles are made from river snails and pork bones, which are stewed for hours with black cardamom, fennel seed, dried tangerine peel, cassia bark, cloves, white pepper, bay leaf, licorice root, sand ginger, and star anise. In Liuzhou, Guangxi Zhuang autonomous region, luosifen is usually sold from roadside stands or in night markets. When served in luxury hotel restaurants in Liuzhou, snails may be included in the dish. In recent years, several luosifen restaurants have been established in Beijing, Shanghai, Hong Kong, and even overseas.
Listed as an intangible cultural heritage for Guangxi in 2008, the dish was featured in the hit foodie-travel show A Bite of China in 2012.
