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.

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.'

This article offers an in-depth interpretation of Lichun (the Beginning of Spring), the first of the Twenty-Four Solar Terms, through the multiple lenses of pre-Qin Confucian and Daoist philosophy, philology, and astronomical phenomenology. By tracing the origin of the character "chun" (萅), the image of the three yang lines ascending in the Tai hexagram, and the mythic archetype of the wood spirit Goumang, it reveals the profound significance of Lichun as the node of the year's beginning and the origination of all things, returning readers to the ancient world of the ancestors' communion between Heaven and humanity.

Starting from a brief episode in the Analects, in which the noble Wenzi of Wei promotes his own household steward, Zhuan, to stand alongside him among the lords, this essay reads that small event against the great declarations of freedom and equality since the Renaissance: the West places its ideal at the starting line, while the pre-Qin thinkers built the ideal into lived reality.

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.
