The ""center"" serves as a metaphor for a dehumanized urban model: all movement and development of people and objects revolve around a hollow, illusory core. Robots drifting through ruins in the deep sea suggest the collapse of this center and the psychological dislocation experienced under a high-pressure society. The filmmaker is from Beijing – a vast and ever-expanding city – and this work is an abstract response to her perception of her hometown's reality.
