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 Great Heat (Dashu), the twelfth of the twenty-four solar terms, through the lenses of pre-Qin Confucian and Daoist philosophy, classical etymology, and astronomical phenology. It reveals the cosmic significance of the sun reaching ecliptic longitude 120°, when summer heat attains its zenith, and explores the Earth virtue of late summer, the metamorphosis of rotting grass into fireflies, and the hexagram Dun with its two rising yin lines — illuminating the ancient wisdom of reversal at the extreme and counterbalancing excess.

This article offers a deep reading of the core proposition in the Xici Shangzhuan — 'What the junzi dwells in and finds peace in is the order of the Yi' — integrating the pre-Qin context, the Confucian scholarly lineage, and the structure of the Zhouyi to elucidate how the junzi, by embodying the Way of Heaven and Earth, takes the Yi as the foundation of settled existence, contemplates the images and savors the statements, and ultimately attains the state of 'auspiciousness with nothing unfavorable.'

This article offers an in-depth reading of the central proposition 'When the inner universe is tranquil and settled, celestial light emanates' from the Gengsang Chu chapter of the Zhuangzi, integrating pre-Qin classical sources to elucidate its five-layered philosophical architecture: inner stillness, the sympathetic resonance of Heaven and humanity, the transcendence of intellective limits, and the order of the celestial Way.
