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 deep reading of Great Cold (Dahan), the final of the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological analysis, and astronomical and phenological traditions. It reveals the dialectic of extreme cold and returning spring, the cyclic principle that every ending harbors a new beginning, and illuminates the late-winter rites of the Grand Nuo exorcism and the clay ox ceremony—inviting the reader into the ancients' cosmic wisdom of 'tracing origins by returning to endings' and the eternal circle of ceaseless renewal.

This article provides an in-depth analysis of the "Zigong asks about achieving ren" passage from the *Analects' Gongye Chang* chapter. It critically examines the relationship between the aphorism "A craftsman wishing to do his work well must first sharpen his tools" and the socio-ethical environment, exploring Zigong's cultivation as a "tool" and revealing Confucian methodology for practicing *ren* within concrete socio-political relations, offering guidance for practical personalities.

This article offers an in-depth analysis of the core proposition of 'yao effecting and xiang imaging' in the Xici zhuan (Great Commentary) of the Zhouyi, examining the dynamic and static distinction between 'effecting' and 'imaging,' tracing the referent of 'this,' and elucidating how yao and xiang constitute the epistemological framework through which the Way of the Yi reveals the subtle and the manifest.
