Philosophy of existentialism is not an abstract about the consciousness, concept and essence of the traditional philosophy, but pays attention to the existence and focuses on life. It is not about the existence of people in reality, but about the spirit of existence. This kind of mental consciousness (often refers to fear, anxiety, despair and other low sense, morbid psychological consciousness) is in the opposition with social existence and reality of inpidual existence. It is considered to be the only real existence. In Sartrean's existentialism, its principle is mentioned about the "freedom of choice", which can be thought to be the essence of existentialism (Sartre, 1948). The core of existentialism is freedom. People is absolutely free in the choice of their own actions. It is believed that in this world, each one has his or her freedom to adapt to various environments. He or she takes various actions to make a "freedom of choice". Sartrean believes that in front of things, if someone does not make a free choice in accordance with the inpidual wills, this person is tantamount to losing the personality and self. Therefore, this person could not be regarded as a real existence.文献综述
