'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.'

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.

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 an in-depth analysis of the core proposition of 'yao effecting and xiang imaging' in the Xici zhuan (Great Commentary) of the Zhouyi, examining the dynamic and static distinction between 'effecting' and 'imaging,' tracing the referent of 'this,' and elucidating how yao and xiang constitute the epistemological framework through which the Way of the Yi reveals the subtle and the manifest.

This article offers an in-depth interpretation of Liqiu (Start of Autumn) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, the original meanings of Chinese characters, and astronomical-phenological perspectives. By examining the etymological roots of 'qiu' (autumn) as grain-and-fire, the astronomical coordinate of 135° solar longitude, and the image of Hexagram Pi (Standstill) from the Yijing — 'Heaven and Earth do not interact' — it reveals Liqiu as the pivotal moment when all things shift from 'growth' to 'gathering,' illuminating the virtue of Metal, the onset of solemn killing, and the ancient roots of the autumnal grief tradition.
