From the perspective of Piaget’s Genetic Epistemology,we will discuss the process of the development of the concept system of the five elements theory.We try to clarify what are the main stages of the five elements theory during its long and glorious development history,and what is the necessary connection between them in the process of development from one main stage to the next one,and what are the characteristics of these stages.Based on the analysis,we think that Piaget’s theory of “four different development stages” can explain the evolution of the development process of the theory of the five elements.
