In East of Eden, Lee, American Chinese, who well understands and acknowledges the fact that the Chinese suffer the racial discrimination in America, establishes a new moral system with his own wisdom and philosophy and is well accepted by the American society. He wins his personal triumph by subverting the traditional character which has become the stereotype and prevailed for a long time in the western cultures. By analyzing Lee's profound philosophy of life, his optimistically confronting history and sins, his interpretation and practice of free will, Steinbeck tries to help the American construct a new moral system with the aid of Chinese culture and help the American out of the spiritual dilemma.
