Featuring karst landscapes, Lianzhou Underground River is a well-known tourist attraction in southern China.
The underground stream passes through the bottom of four hills, with a total length of 1,500 meters and a water depth of one to seven meters.
The stalactites in the karst cave, which generally takes hundreds of thousands of years to form, are appealing to travelers.
Relying on the tourist resources, nearby villages have also found their ways to prosperity.
