Wu is one of the key figures and earliest participants in the digitization endeavor to better preserve and facilitate the research into the art of the Mogao Caves since the 1980s, Fan Jinshi, honorary director of the academy, writes in preface of the exhibition.

So far, the academy has completed high-definition digital scanning of 290 caves of the Mogao Caves, panoramic roaming programs for 162 caves, and three-dimensional reconstruction of 45 painted sculptures and seven key relic sites, she adds.

The exhibition runs through Aug 15.
