Luosifen, a native to Liuzhou in China's Guangxi province, is a dish consisting of a snail-based broth, rice noodles, and an array of additional ingredients, typically including pickled bamboo shoots, peanuts, tofu skins, and green vegetables.

The hot and spicy taste comes from an elaborate concoction of spices and herbs that's used to make the broth, as well as a sizable amount of chili oil that's added to the finished soup at the end. Luosifen is typically sold by street vendors and only rarely served in restaurants, with each place having their secret recipe.

Recently, specialized luosifen restaurants started to appear in numerous Chinese cities, but also abroad.
