The 45-year-old guest researcher is dedicated to preserving images of the Great Wall, which involves the use of the latest technology, such as drones, to collect "the most complete, accurate, three-dimensional images of the Great Wall".

By capturing successive scan-quality images and utilizing software to create 3D models, the project produces in-depth renderings of the site that can be applied to various research fields, such as showcasing cultural relics, investigating areas of damage, and analyzing the causes of harm, according to Li.
