The elements of "beginning" and "end" under the dimension of "time" and "place" are extremely core and valuable contents in the system of Zhouyi, which have at least four meanings in the derivations. As a measure of the time dimension, it represents the two parts of the beginning and the end of things;As a logical analysis of the relationship between the cause and effect of the development of things;As the essence of the existence process of things, it represents the existence process of things, that is, the whole process of things from beginning to end. As the function category between Yin and Yang, it means the intersection and separation between Yin and Yang. Based on the concepts of "beginning" and "end", it introduced the original idea of "ending" and "fear of ending", which diluted the mystery and religious color of Zhouyi, laid the philosophical system of Zhouyi, and promoted the transformation of Zhouyi from divination to neo-Confucianism. An in-depth analysis of the "beginning" and "end" views of Zhouyi and its cultural spirit is of great significance for us to deeply understand the core categories of Zhouyi, such as the concept of life and time and place.
