Starting from the mathematical structure of Taiji, the Two Modes, Four Images, and Eight Trigrams in the Book of Changes, this article systematically explores the information-carrying capacity of Bazi and Qimen Dunjia as divinatory systems. Through analysis of Yin-Yang, the Five Phases, the Hetu and Luoshu, and other classical mathematical foundations, it seeks to provide a unified perspective for measuring and comparing the information volume of these two arts.

A thorough exploration of the principles behind Qimen Dunjia's capacity for 'multiple judgments from a single chart.' Through holographic cosmology, multidimensional coordinate systems, the symbolic system of universal correspondences, and the shifting of Taiji focal points, this article dissects the core mechanisms of what is regarded as the highest art of divination in ancient China.

'An in-depth analysis of the core differences between the "Life Chart" (Mingpan / Zhongshen Pan) and the "Hourly Chart" (Shi Pan / Shijia Qimen) in Qimen Dunjia. Exploring from the dimensions of temporal scope, analytical logic, application range, and philosophical essence, this article reveals the dialectical relationship between fate and contingency in Yixue divination.'

This article offers a deep reading of Jingzhe (Awakening of Insects) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. Through an examination of the historical renaming from 'Qizhe' to 'Jingzhe,' an analysis of how spring thunder rouses hibernating creatures, and the cosmic vision of the Zhen (Thunder) hexagram's 'the sovereign emerges from Zhen' in the Book of Changes, the essay reveals the critical threshold at which life transitions from dormancy to vigorous action, illuminating the ancient Way of bending and stretching to preserve one's being.

This article undertakes an in-depth exploration of the proposition 'nourishing the will by emulating the numinous turtle' (yang zhi fa ling gui) in the Guiguzi, examining the symbolic significance of the turtle in high antiquity, the wu-xi shamanic tradition, turtle-shell divination culture, ritual status, and longevity philosophy from multiple dimensions, revealing the profound philosophical thought and methodology of spiritual cultivation it embodies, and striving to restore its original meaning within the pre-Qin intellectual context.

This article offers a deep reading of Yushui (Rain Water) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymology, and astronomical phenology. Through an examination of the original meanings of the characters "雨" (rain) and "水" (water), the astronomical positioning of the sun at 330° of celestial longitude, and the three phenological signs of the term, combined with Laozi's teaching that 'the highest good is like water,' Guanzi's view of water as the origin of all things, and the Book of Changes' vision of Heaven-One begetting water and clouds moving to bring forth rain, the essay reveals the virtue of water and the meaning—between Heaven and humanity—of spring rain nourishing all things.
