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.'

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.

This study offers a profound analysis of the *Zhengming* chapter in the *Xunzi*, specifically examining the philosophical implications of "the perfected names of the later kings" and "dispersed names." By situating Xunzi’s theory within the broader discourse of Pre-Qin thought, the article elucidates how the rectification of names functions as a critical nexus for political governance, social order, and epistemological framework.

An introduction to the Xici Zhuan (Appended Statements) of the Zhouyi, written for a faraway reader. Beginning with the fundamental concepts of hexagrams, lines, yin-yang, and the high and the low, it clarifies the composition and reading of the Xici, dispels the most common misunderstandings of beginners and overseas readers, and paves the way for a close study of the twelve chapters of the Upper Xici.

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.
