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 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.

This article offers a deep reading of the core passage in the Guanzi: Neiye — 'That which can transform a single thing is called shen (spirit); that which can adapt to a single affair is called zhi (wisdom)' — systematically tracing the philosophical categories of shen, zhi, jing, qi, and dao in the pre-Qin era, elucidating their pivotal role in the cultivation of mind and character and in the Way of inner sageliness and outer kingliness, striving to recover the original intent of the ancients.

This article explores Chushu (End of Heat) from the perspectives of pre-Qin Confucian and Daoist philosophy, etymological origins, and astronomical phenology, revealing the wisdom shared between 'heat ceases at this point' and 'knowing where to stop, one finds stability.' Through analysis of the character chu (to stop), the hawk's ritual offering of birds, the onset of heaven and earth's solemnity, and the grain's ascent as a return to origins, the article illuminates the ancient way of measured restraint and reverent remembrance.

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.
