The word of Zhengshizhiyin came from two sources, Metaphysics and Confucianism. But it was being used in chaos by a lot of literature researchers for being confused by its origin. So we need to differentiate and analysis the word from some aspects such as the generation process, the certain context and some researchers’ misuses. Through the comparison of collation and historical analysis, we consider it can be used to refer to Zhengshi’s metaphysical voice, also refer to classic music and literature. Though some modern researchers believed it also can be used to refer to the Zhengshi’s literature, but we still insist on the basic fact because it already brought many difficulties and confusions.
