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 investigates the central thesis of the Xi Ci Shang Zhuan (Great Commentary, Upper Section) of the Zhouyi — how the sage transforms the hidden textures of reality (ze) into externalized images (xiang) through the cognitive leap of 'gazing upward and examining below.' It reveals the inner connection between yao (lines) and ancient ceremonial institutions, reconstructing the foundations of Yijing theory.

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 offers a deep reading of Major Snow (Daxue) among the twenty-four solar terms, drawing upon pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. It analyzes the etymology of 'da means flourishing — at this point snow flourishes,' examines the Hexagram of Return (Fu) with its 'single yang returning' in the zi month, and reveals the virtue of auspicious snow sealing and protecting nascent yang, along with the profound cosmology of 'supreme yin birthing yang — the heart of Heaven and Earth.'
