Abstract：In literature creation, most authors' drive originates from their painful experience of deficiency. This is certainly true in Mo Yan's case, who has chronically suffered from his painful childhood experience deficiency of materials and love. Extreme mental depression inspired Mo Yan 's creativity, which contributed to his unique attitude and writing style. On the one hand, he released his emotion and got spiritual freedom as a compensation with the aid of extreme wild imagination; on the other hand, his desire to overcome inferiority prompted him to challenge the tradition and authority, which is reflected vividly in his works. Literature creation is a psychological therapy for Mo Yan to get rid of his childhood traumatic memory, and a streak of morbidity is inevitable due to the excessive suppression.
