1 . The exhibit, Digital Dunhuang — Tales of Heaven and Earth, which was held at the Hong Kong Heritage Museum, brought to Hong Kong more than 100 exhibits including the visual murals and other related programs that could allow visitors to learn about the art and history of the Mogao Caves in a fun way.

“Dunhuang was an international city, a place where East met West, on the old Silk Road. So the Mogao Caves, which were completed in a period of over 1,000 years, record the ways of life and beliefs of the different peoples that crossed paths there,” explained Fion Lin of Hong Kong Heritage Museum.

Visitors can now get up close and personal with these faraway treasures without having to step into the caves, thanks to the digitization project of the Dunhuang Academy, a pioneer that has made great progress in the digitization and 3D scanning of the Dunhuang treasures.

“Studies have shown that in a cave, both temperature and CO₂ concentration level can rise with 15 tourists inside for ten minutes. As a result, the wall paintings are going to eventually fade. Digital technology has helped to strike a balance between sharing the treasures and protecting them,” said Lin.

However, digitization of the caves faces many challenges such as poor lighting and rough wall surfaces. On average, 40,000 pictures have to be taken to cover 300 m². Great amount of efforts have been made to piece the pictures together. What the exhibition presented is the result of years of hard work.

During the exhibition period, a mini display on Dunhuang music culture was also being held at the Museum for public participation.
