The Maijishan Grottoes, located in Tianshui, northwest China's Gansu province, are named after their resemblance to stacks of wheat.

Maijishan Grottoes are a 1,600-year-old UNESCO World Heritage site consisting of 221 caves connected by trestle roads suspended above the ground.

Using digital measurement, carbon-14 dating and other technologies, all cultural relics information in cave 74 and cave 78 of Maijishan Grottoes has been recorded comprehensively, objectively, scientifically and accurately in various forms such as text, digital mapping and image. This laid a foundation for the comprehensive development of the archaeological report of Maijishan Grottoes.
