These exquisite carvings are found about 162 kilometers from Chongqing. They date back more than a thousand years, having been created during a period that began in the late Tang Dynasty (618-907) and ended during the Song Dynasty (960-1279). The forty groups of more than five thousand pieces of stone carvings are scattered within the boundary of the county, especially on North Hill (Beishan) and Precious Crown Hill (Baodingshan). They constitute the largest and most valuable collection of ancient Buddhist stone carvings in China.
