The Maiji Mountain Grottoes are located in Tianshui, Northwest China's Gansu Province. The Grottoes are known for collecting prolific clay sculptures that were predominantly created during the Northern Dynasties 386-589. In recent years, in sharing experiences with the Dunhuang Academy, the site has also been committed to developing digital conservative schemes. The recent cultural tourism boom has brought a surging number of tourists to Tianshui and to the Grottoes.(Photo: Chen Tao/GT)
