Huang di's Four Classics introduces the first full-scale Yin-Yang theory. The ancient idea of Yin-Yang could be classified systematically throughout Huang di's Four Classics and make itself the cause of creation, movement, and variation. The Tao of essence and Reason-Law(理法) is a single 'One'(一) and completes the reality of Tao adopting Yin-Yang as an elementary. The elementary of Yin-Yang has rules and laws and then the Tao manifest itself through Yin-Yang. The features of Yin-Yang theory in Huang di's Four Classics are placed on the explanation of the structure of the universe embodied as class and system. The class and system are the structured worlds in the space based on the upper and lower sides Yin-Yang idea(上下陰陽觀). It means the system by Yin-Yang theory, corresponding to the flat structure of the Sky and the Earth mentioned in Gaitian theory, one of the ancient theory of the universe structure. By adopting Huang di's Four Classics' Tian-zhi Yin-Yang theory(天地陰陽論) and developing the class system in human bodies, The Hwangjenegyeng appreciates human bodies as a whole. In addition, by applying Four seasons Yin-Yang theory not only to human bodies but also to the space of Liu-he(六合) and the time of Four Seasons(四時), it developed Yin-Yang theory of Huang di's Four Classics more abundantly and embodied Yin-Yang theory in many fields including physiology, pathology, diagnostics, and prescriptions.

All creatures are living in the space and time. As the space and time are prior to experience, they are preconditions for an incident to happen and preconditions for each other to coexist as well. Therefore, time can be recognized through the change of space and the space can be understood by the passage of time. In western philosophy, the space was understood as an object, place, interval, mind and etc. In oriental philosophy, even though one space is just a part of bigger space, the space may represent the universal space, and the various spaces are no more than a space. The space itself doesn't have any color, form, beginning and end, or liu-he(六合). However, it is the biggest concept that we can find everywhere. In order to understand the space, we need to find our position by expressing subjective positions like above and below, left and right, before and after, and objective positions like high and low, east and west, south and north. In oriental philosophy, the sun is the standard point in finding position; its front side is south, the backside is north, the left side is east, the right side is west, the upper side is south and the lower side north. Based on the finding position which is stated above and by taking each characteristics of he-luo-xi-wen(河洛羲文) and interrelations among them, the space can be modeled. Followings are the results obtained from this study: Tian doesn't fill in west and north. Di doesn't fill in east and south. Tian-dao(天道) turns to left, and Di-dao(地道) turns to right. There is no direct way to get to Dui-chong-fang without passing by Zhong-gong(中宮). The solid figure of eighty-one Bian-ju(變局) and sixty-four Gua-tu(卦圖).
