The work "Dunhuang Dream" is an innovative digital performance program short film produced using AIGC technology. The short film adopts the structure of "leading VCR main stage performance" and constructs a space-time theater through the virtual and real. The VCR part combines Dunhuang history and culture to lead to the theme. In the main stage part, a digital grotto stage combining a surrounding curved screen, a lifting lotus platform and a holographic curtain was designed to transform the whole scene into an immersive performing arts space. The program shows classic elements such as "rebound pipa", "thousand hand Guanyin" and "dreamlike opera" in Dunhuang dance, highlighting the sacred charm of Dunhuang culture.
