Cai Ruei-Heng’s enigmatic paintings are characterized by the combination of figurative depiction and anxious-like quality. He paints with personal memories from the times with animals and ghosts, which represents the metaphor of the confusion he feels in life. He also questions the capability for human and creature to maintain the sense of self, which he continues to search through the similarities between both lives.he obsessed with a wandering status like a ghost. Perhaps this is a result of some sort of mischievous attitude I have being at the mercy of current circumstances while acting apathetic.
