   Two young restorers gather 3D data from a statue in the Yungang Grottoes in Datong, Shanxi province, on April 6, 2023. High-precision mapping technology, three-dimensional laser scanning technology, computer network technology, and other scientific and technological means are used to collect information from the grottoes, building a "digital archive" for YungangGrottoes, which makes the ancient grottoes "come alive".
