Digital technology can immortalize cultural relics, and the Yungang Grottoes are now benefiting from it. Located in Datong City in north China's Shanxi Province, the site is one of China's most renowned Buddhist temples. The site features nearly 300 caves of different sizes, but 1,500 years of harsh weather and elements contributed to the deterioration of the sculptures. In recent years, digital technology has them better protected. CGTN reporter Hu Chao will show you the statues and caves and explain how they are better protected by digital technology.
