For four decades, archaeologists and scientists have worked to protect the Mogao Grottoes at Dunhuang, a world heritage site in Northwest China.

Instead of limiting tourist number, they are bringing the ancient cultural heritage to a wider audience through digitization.

More than 3,000 miles from Dunhuang, the Mogao caves, murals and painted sculptures are meeting audiences at the Wanlin Art Museum on the campus of Wuhan University in Wuhan, Hubei province.
