A basketball court has been built inside a natural cave in southwestern China's Xinchun Village.
The video, shot in Bijie City in Guizhou Province on May 15, shows several villagers playing basketball down inside a karst cave.
According to reports, villagers spent around £27,000 (234,366Yuan) to built the 1000-square-metre court.
The project started in February 2016 and was finished in two years.
