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 a deep reading of Minor Heat (Xiaoshu) through the dimensions of pre-Qin Confucian and Daoist philosophy, classical etymology, and astronomy and phenology. It analyzes the dual meanings of heat in the character 'shu' and the moderation implied by 'minor' as yet unextreme, reveals the noble person's way of withdrawing at the height of flourishing and retreating while the current still runs strong as expressed in the hexagram Dun (Retreat), and explores the ancient wisdom of Earth virtue presiding at the center of late summer and of nurturing the heart through concealment and stillness — inviting readers to return to a world of resonance between heaven and humanity.

This article takes as its core text the 'Ox Mountain' chapter from the Gaozi section of the Mengzi, and draws upon a wide range of pre-Qin philosophical sources to analyze the argumentative structure for innate human goodness, the mechanisms by which external forces damage the heart-mind, and the philosophical foundations and cultivation methods of the theory of innate goodness.

This article offers a deeply layered reading of Cold Dew (Hanlu) from the perspectives of pre-Qin Confucian and Daoist philosophy, the original meanings of Chinese characters, astronomy and phenology, and the Double Ninth chrysanthemum festival. It examines the gradual shift of dew from 'white' to 'cold,' the principle of reversal at the extremity of decline embodied in the Bo hexagram's five yin lines stripping away yang yet preserving the 'great fruit uneaten,' the gentleman's integrity symbolized by chrysanthemums defying autumn frost, and the ritual propriety of wild geese arriving as guests — revealing the hidden seed of renewal concealed within the stripping away of yang.
