This 3D film explores Qiu's sense of division and shuttle as a bicultural artist. The butterfly in the dream travels freely through space and time, just as for Qiu, only in dreams can portals from both worlds appear at the same time. The butterfly is given different identities and meanings in different cultures, but because it is a butterfly, it can move freely. In an era of information explosion, it's hard to escape the echo chambers, but whether for Qiu, it's the fragmentation of cultural identities that allows her to see both sides of the world exist at the same time, and the portals are open for her.
