Nestled in China's northwestern Gansu Province, Dunhuang is a desert-oasis city that houses exquisite ancient mural arts within its grottoes and caves, hidden beneath the sands for millennia. The Dunhuang Academy, a leading research and cultural institution, is dedicated to preserving these vibrant artworks from the ravages of time. By harnessing digital technology, they aim to mitigate the impact of tourism while ensuring that these cultural treasures continue to captivate the world. CGTN's Zhu Luoman reports.
