A cup of instant noodles used to be a "must" for Liang Haizhen wherever she traveled, as she found them both cheap and convenient.

But in recent years, the 33-year-old, who comes from a small county in the Guangxi Zhuang autonomous region, has turned to a traditional dish from the area - instant Liuzhou river snail rice noodles.

"In the past, we could only eat the river snail rice noodles at a restaurant, but now this dish has been developed and it only takes a few minutes to make with hot water, so I can enjoy a cup as I travel," said Liang, who has become an agent for the product and sells it through social media platforms.
