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 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.'

Argued across four dimensions — the judgment text, the line's position, cross-verification between the Classic and its Commentary, and philosophical meaning — this essay shows why the top nine of Hexagram Dayou (Great Possession) stands first among the 384 lines of the Book of Changes: 'Aided by Heaven, fortune — nothing unfavorable' is the only unconditional, supreme judgment in the entire classic, while the Great Treatise, speaking in the Master's own voice, supplies the operative mechanism for attaining such fortune — 'treading on trust, cherishing compliance, and honoring the worthy.'

This article offers a deep investigation of the Hexagram Tong Ren (Fellowship with Others) from the Yijing (Book of Changes), grounded in pre-Qin Confucian and Daoist thought and archaic culture, tracing layer by layer the meanings of the hexagram image, judgment, and line statements. Through a careful analysis of the distinction between 'sameness' (tong) and 'harmony' (he), and drawing on the structural logic of the Xu Gua Zhuan (Sequence of Hexagrams), the article illuminates Tong Ren's pivotal role in the transition from obstruction to openness, revealing its primordial wisdom of seeking Great Unity within difference.
