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.

A close reading of Chapter One of the Upper Xici within the context of pre-Qin thought, moving through the layers of Heaven and Earth, Qian and Kun, the firm and the yielding, image and form, change, ease and simplicity, virtue and achievement, and the taking of one's place -- to see how the Yi runs through the Way of Heaven, the Way of Earth, and the Way of Man.

'An in-depth analysis of Hexagram 14 (Da You) of the I Ching from the perspectives of paleography and Zhou dynasty history. This article explores the original theological imagery of Da You, the political structure of Li above Qian below, and the philosophical ladder of self-cultivation and governance from commoner to Son of Heaven, revealing the ethics of wealth and the concept of Heavenly Mandate in the pre-Qin worldview.'

This article offers an in-depth reading of the core proposition concerning the Xian (Influence/Resonance) hexagram of the Yijing: 'The Xian of the Yi reveals husband and wife. The way of husband and wife must not be left uncorrected, for it is the root of ruler-minister and father-son relations.' It systematically examines the hexagram's position in the structure of the Yi, the etymological relationship between xian and gan (resonance), and analyzes how 'the soft above and the firm below' embodies the principle of yin-yang sympathetic resonance and its foundational significance for pre-Qin ethical order.
