This series is mainly about Socrates's thought ''know yourself''. Self-awareness as a human being. To know yourself is the foundation of what a human is. The mirror, as a medium of self-knowledge, appears repeatedly in my work. I as an individual, through the mirror, explore my relationship with reality, my relationship with fantasy. As a "human", I need to have a clear self-cognition, which is the fundamental difference between human beings and animals. An animal is an animal because it can not be conscious of its own existence as an individual animal. But man can realize that he has the social attributes of man and become a man. Through these series of mirrors and witches criticize the current society's indifference to self-reflection.
