'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 a deep reading of Minor Heat (Xiaoshu) through the dimensions of pre-Qin Confucian and Daoist philosophy, classical etymology, and astronomy and phenology. It analyzes the dual meanings of heat in the character 'shu' and the moderation implied by 'minor' as yet unextreme, reveals the noble person's way of withdrawing at the height of flourishing and retreating while the current still runs strong as expressed in the hexagram Dun (Retreat), and explores the ancient wisdom of Earth virtue presiding at the center of late summer and of nurturing the heart through concealment and stillness — inviting readers to return to a world of resonance between heaven and humanity.

This article offers an in-depth interpretation of the opening discourse on the Dao in the Guanzi 'Neiye' (Inner Cultivation), analyzing the threefold nature of 'thorough and dense, broad and expansive, firm and steadfast,' its dialectical unity, and its significance for self-cultivation within the intellectual context of pre-Qin and high antiquity.

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.
