'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.

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.

This article systematically investigates the fourteenth hexagram of the Yijing, 'Fire over Heaven — Great Possession' (Huo Tian Da You), analyzing its trigram structure of Li above Qian below, elucidating the rich connotations of 'Great Possession,' and drawing upon pre-Qin literature to expound the principle of 'one yielding line in the place of honor, five firm lines responding to it' — the way of grand virtue and great enterprise — revealing its profound significance in ancient political philosophy.

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.
