'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.

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 article offers a philological and philosophical examination of the Qingming solar term, exploring the cosmic significance and humanistic ideals embodied in the concepts of "clarity" (qing) and "luminosity" (ming). Through a comprehensive analysis of its dual nature as both a seasonal juncture and a cultural festival, the study elucidates the traditional worldview of the unity of man and nature, revealing the profound reflections within Chinese civilization on life, death, and ethical order.

This article provides an in-depth analysis of Lixia (the Beginning of Summer) through the lenses of pre-Qin Confucian and Daoist philosophy, etymological roots, and astronomical observation, elucidating its significance as the critical juncture where the cosmic momentum shifts from "birth" to "growth." By examining the evolution of the character "xia" (夏) and the movement of the star Antares, the study reveals the profound wisdom behind the ancient mandate of "respectfully bestowing the seasons" and the harmonious worldview of unity between humanity and the cosmos.
