A child's thinking is more direct and less metaphorical. Could this drawing be an actual representation of the crime scene that he witnessed?
The house is black, meaning the time of the crime was at night, and the people inside the house are red—they probably represent his parents, the victims. This is the most direct interpretation.
Chen Ge tried looking at this painting from multiple angles. The boy had a hasty artistic style; all the human shapes looked the same and had no defining features. Chen Ge could not even tell their gender.
Wait, the red humans probably aren't referring to his parents, there are way too many of them in the drawing. Chen Ge tried counting the number of red people, but every time he ended up with a different number. The drawing is too messy. What is the boy actually trying to communicate with it?
