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.

'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.'

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.

This article offers an in-depth analysis of the core proposition of 'yao effecting and xiang imaging' in the Xici zhuan (Great Commentary) of the Zhouyi, examining the dynamic and static distinction between 'effecting' and 'imaging,' tracing the referent of 'this,' and elucidating how yao and xiang constitute the epistemological framework through which the Way of the Yi reveals the subtle and the manifest.

This article offers an in-depth interpretation of Xiaoman (Grain Full), one of the twenty-four solar terms, drawing on pre-Qin Confucian and Daoist philosophy, philology, astronomy, and phenology. Through the etymology of "full yet not overflowing," and the phenological signs of bitter herbs flourishing and wheat's autumn arriving, it reveals the deep meaning behind why the twenty-four solar terms include a "small fullness" (Xiaoman) but no "great fullness"—illuminating the ancient Chinese wisdom of guarding against excess, prizing humility, of loss following fullness and gain following modesty, of completeness found even in imperfection, and the venerable cosmology of the unity of Heaven and humanity.

This paper examines the physical underpinnings of pre-Qin theories of *qi*, positing *qi* as a unified abstraction of matter, energy, and information. By analyzing texts such as those by Zhuangzi and Laozi, it reveals a cognitive revolution within pre-Qin thought, transitioning from mysticism towards naturalistic rationality and redefining the core value and scientific significance of *qi* in cosmology and life sciences.
