A visitor takes photos at an exhibition on grotto art at the Chongqing China Three Gorges Museum on June 18, 2025 in Southwest China's Chongqing Municipality. Through digital technology and physical cloning, the exhibition overcomes the geographical limitations of immovable cultural relics and showcases over 200 exhibits from the Mogao Caves in Dunhuang, Northwest China's Gansu Province, and the Dazu Rock Carvings in Chongqing, both UNESCO World Heritage Sites.
