This year marks the 80th anniversary of the founding of the Dunhuang Academy, which currently oversees the Mogao Caves and several other relics sites in Gansu.
The temporary exhibition at the Zhejiang Provincial Museum, running through Oct 20, is in commemoration of the 120th anniversary of Chang's birth, said Zhang Yiqing, curator of the exhibition.
Through Chang's own depiction, the exhibition gives a display of early conservation efforts of the Dunhuang Academy, while tracing Chang's artistic exploration and achievements before and after he went back from France.
