An aerial drone photo taken on July 22, 2025 shows a tourist playing a “super giant swing“ in a giant sinkhole in Kaiyang County, southwest China's Guizhou Province. Guizhou Province is renowned for its extensive karst landscape, which is distinguished by its numerous giant sinkholes, locally called “tiankeng“ or “heavenly pits.“ The natural sinkholes are increasingly recognized for their unique tourism values.
