According to a legend in the 1980s, some starving tourists traveled to Liuzhou and came across a rice noodle restaurant that was closed; however, the owner still served them. The bone soup was out of order, and only snail soup was available, so the owner poured cooked rice noodles into the snail soup and served the tourists with vegetables, peanuts, and a bean curd stick side dish. The tourists liked the dish, which led to the owner improving the recipe and production process, slowly shaping the prototype of snail noodle soup.
