'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.

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 philosophical core, the detailed procedure of the Four Operations and Eighteen Transformations, and the mathematical mysteries of non-uniform probability in the Yijing's Great Expansion milfoil divination method, combined with the classic case of Duke Mu of Qin's campaign against Jin from the Zuo Zhuan (Duke Xi, Year 15) to reconstruct the hexagram-interpretation logic of the pre-Qin perspective.

Drawing on pre-Qin Confucian and Daoist philosophy, etymology, astronomy, phenology, and the legend of Cangjie's invention of writing, this article offers an in-depth reading of the Guyu (Grain Rain) solar term. It examines the humane grace of Heaven and Earth embodied in "rain giving birth to the hundred grains," the firm-yet-yielding way of hexagram Guai's "resolving away the last remnant of yin," and the profound meaning behind "Heaven rained down millet, and ghosts wept in the night" at the origin of writing—returning readers to the ancient world of the unity of Heaven and humanity.

This article provides a rigorous exegesis of the *Analects* passage regarding Zang Wenzhong’s "usurpation of position," utilizing philological analysis and historical contextualization to examine the political ethics underlying his failure to promote the virtuous Liuxia Hui. By synthesizing evidence from the *Zuo Zhuan* and the *Records of the Grand Historian*, the study elucidates Confucius's profound discourse on the legitimacy of political authority and the moral imperatives of personnel selection.
