"We are proud to see the exhibition of Dunhuang art and culture at Wuhan University," said Huang Xianfeng, professor of remote engineering at the university.

The exhibition is special for Huang, who has been part of the scientific team digitizing Dunhuang in recent decades.

"Technology has transformed the way ancient culture is inherited," Huang said. "Digital recording, protection and replication has allowed more people to get in touch with ancient civilization."
