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.

'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.'

This article offers a deeply layered reading of Cold Dew (Hanlu) from the perspectives of pre-Qin Confucian and Daoist philosophy, the original meanings of Chinese characters, astronomy and phenology, and the Double Ninth chrysanthemum festival. It examines the gradual shift of dew from 'white' to 'cold,' the principle of reversal at the extremity of decline embodied in the Bo hexagram's five yin lines stripping away yang yet preserving the 'great fruit uneaten,' the gentleman's integrity symbolized by chrysanthemums defying autumn frost, and the ritual propriety of wild geese arriving as guests — revealing the hidden seed of renewal concealed within the stripping away of yang.

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 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.
