The nonlinear narrative breaks the one-directional narrative rule of linear narrative time and infuses new vitality into literature, drama, film and other arts with its complex and changeable narrative mode. The characteristics of nonlinear narrative mainly include the following aspects: time sequence is disrupted, multi-line narrative, multi-perspective narrative, etc. The arrangement of the story is no longer based on the realistic sequence of events, but the structure of the whole film is based on the non-realistic psychology.
