This article pays special attention on how does Taoist Oriental civilization save the decline of Western spiritual world, and the ＂Eastern＂ color, as well as the concept of good and evil conflict and the coincidence of Steinbeck＇s theme with Chinese culture. In this sense, Steinbeck＇s works have a great association with the oriental.展开更多
