"The Yungang murals are the epitome of traditional Chinese craftsmanship," Dai says. "I can always feel and touch the ancient artisans' devotion to the murals they created."
Besides manual labor, digital and information technologies are being used more in Yungang, such as digital scanning and 3D printing. These new technologies enable visitors to enjoy the grottoes with virtual reality glasses to explore the historical site in boundless time and space.
