This is the famous Stone Forest, the product of countless years of erosion, producing a maze of deep gullies and sharp-edged pinnacles. Limestone has the strange property that it dissolves in rainwater. Over many thousands of years water has corroded its way deep into the heart of the bedrock itself. This natural wonder is a famous tourist spot, receiving close to 2 million visitors each year. The Chinese are fond of curiously shaped rocks and many have been given fanciful names. No prizes for guessing what this one is called.
