On the formation of taiji diagram from the perspective of twenty-four solar terms.

This paper discusses the forming principle of Taiji Diagram from the perspective of the 24 Solar Terms, and then analyses the trend of Taiji Curves, the Polar Point of Taiji Diagram and the meaning of Yin-Yang fishes' eyes. This paper argues that the Taiji Diagram is originated from the S-style solar term model, or model of S-style Taiji Diagram combining solar term and Yin-yang fish. According to methods provided in this essay, the drawing work of Taiji Diagram could be simplified. This paper also further integrates the model diagram with the Chinese traditional medicine, especially with main and collateral channels, Zang-Fu organs and hours of daily time, and directly reveals the relationship among them and sets up two model figures: one is the S-style Taiji Yin-Yang Fishes and Main and Collateral Channels Model Figure, the other is S-style Taiji Yin-Yang Fish and Main and Collateral Channels Hours Model Figure. The Taiji Diagram described in this essay looks like that one black fish (symbolizing Yin) hugs with the other white fish (symbolizing Yang), which contains universal laws and rules of constraints between the Yin-Yang opposites, mutual usages with each other, balance of the ebb and flow, reciprocal transformation, etc. By analyzing the shift and transformation between Yin and Yang of the 24 solar terms in a year, it could not only explain the naming of the Twenty-Four Solar Terms, but also help preserve people's health with the combination between medicine and Yi science. The advantages of preventive medicine of traditional Chinese medicine will be high lighted.
