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 an in-depth reading of the chapters on 'the virtue of ghosts and spirits' and 'sincerity is self-completing' in the Zhongyong, exploring their significance as the core of Confucian metaphysics. Through an analysis of pre-Qin conceptions of ghosts and spirits, it demonstrates that the chapter on spirits serves to prove that 'sincerity cannot be concealed,' and further elucidates how the substance of cheng (sincerity) matches Heaven and supports all things, revealing the ontological foundation of the Doctrine of the Mean.

The Five Combinations of the Heavenly Stems (Jia-Ji combining into Earth, Yi-Geng into Metal, Bing-Xin into Water, Ding-Ren into Wood, Wu-Gui into Fire) constitute one of the most fundamental yet mysterious theories in Chinese metaphysical arts. This article delves into the profound principles behind them, analyzing various conjectures and demonstrations of 'combination and transformation of qi' from dimensions including the Hetu numerology, celestial astronomy, and the Five Phases and Six Qi system, revealing the cosmic vision underlying this ancient law.

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.'
