here are different opinions in academic circles as to whether the text of Tai Yi sheng shui is in fact one work or two. The reason for this lies in a disagreement concerning its thematic and chapter division. Starting from the overall structure of the text,it can be found that Tai Yi sheng shui has a structure similar to that of a general and specific discussions. With this structuring,Tai Yi sheng shui can only be one document,not two different texts. It is however an incomplete philosophical document because it lacks further explanations of the concepts of shen-ming,Yin and Yang,and the four seasons. On this basis,we can revisit the theme of Tai Yi sheng shui,and conclude that its goal is not to describe the generative process of all things in the universe,but rather to illustrate the ontology based on the Tai Yi.
