Located on the west apex of Jiuli Hill, north of Xuzhou, White-cloud Cave is a grotto, formed about 400,000 years ago. There are more than 30 different caves, in which people can see stalactites of grotesque shapes and appearance. Every winter and spring, the mysterious white mists will fly from the caves. To the west of White-cloud caves is the grand Buddhist temple—White-cloud Temple, constructed in the Tang Dynasty in a plain and elegant style.
