The interpretations about Dao in Yi Zhuan range from "the path", "the principle", "the way of Heaven and Earth" to "the metaphysical way", which result from the mutual exercises between ontological and creative interpretations. The content of ontological interpretations is sublimated through creative interpretations; the aim of creative interpretations is to interpret the entity and then construct the ontological system, while its final direction is to search for the origin and pursue the eternity of life. On the one hand, we try to explain the indivisibility between the existence of the universe and the existence of individuals' lives, which must be assimilated and combined with each other. On the other hand, individuals' lives as the physical evidence and practice of the ontological "Dao" manifest not only the richness and perfection of the meaning of "Dao" but also the special values of lives, including the creative interpretations, the ontological interpretations, and the physical evidences of lives.
