This is a moving image about child abuse derived from the "Red, Yellow and Blue Education" incident.A kindergarten in Beijing has been engulfed by a wave of public suspicion and wrath after parents charged that children in a class there were fed pills, jabbed with needles and forced to strip naked.The incident fermented in a short period of time, which broke out the discussions of all walks of life in China and became a heated topic for public opinion. In the film, the red, yellow and blue light are used as the metaphors of 3 scenes of the character's inner world. The red world represents the grown-up girl; the yellow world represents her childhood during which she had been abused; and the blue world represents a rat transformed from the child's inner fear when she was abused. Three worlds intertwine, and the child who had been abused during childhood imagines a rat that can run away in her mind, while the grown-up girl repeatedly warns herself in her childhood memory. But she cannot change the fact of being hurt. The film shows the audience the lifetime harm of child abuse on children and calls for attention to the mental health of children, appeal to people can work together to protect the children.
