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 essay offers an in-depth reading of the passage on 'the imagery of music' (sheng yue zhi xiang) in Xunzi's 'Discourse on Music,' elucidating how musical sounds embody character-qualities that correspond to heaven, earth, and the myriad things, and situating the discussion within Master Xun's Confucian vision of transforming human nature through ritual and music.

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.

This essay offers an in-depth exploration of the Bailu (White Dew) solar term from the perspectives of pre-Qin Confucian and Daoist philosophy, etymological analysis, astronomy and phenology, and the Classic of Poetry's 'Reeds and Rushes' (Jianjia). It examines how dew forms through the interplay of yin and yang qi, the philosophy of concealment and manifestation, the metaphor of morning dew, the celestial shift as yin grows heavy and dew turns white, the eternal longing of 'reeds so grey, white dew turns to frost' — the unattainable figure beyond the autumn waters — and the wisdom of contemplation found in the Guan hexagram's 'great observation above' and 'teaching through the numinous way.'
