'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.

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.

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 offers an in-depth investigation into the pre-Qin, high-antiquity origins and inner rationale of the Six Combinations and their Qi transformations among the Twelve Earthly Branches (e.g., Zi-Chou combining to transform into Earth). Through textual examination of the Earthly Branches' origins, their connection with Jupiter's orbital cycle, the correspondences between the twelve months and the twelve sovereign hexagrams, and the spatial positioning of the four Earth-branches at the four inter-cardinal directions, the essay reveals the profound astronomical and yin-yang philosophical underpinnings of the Earthly Branch system as a cornerstone of Chinese metaphysical arts.

This article offers a deep reading of Jingzhe (Awakening of Insects) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. Through an examination of the historical renaming from 'Qizhe' to 'Jingzhe,' an analysis of how spring thunder rouses hibernating creatures, and the cosmic vision of the Zhen (Thunder) hexagram's 'the sovereign emerges from Zhen' in the Book of Changes, the essay reveals the critical threshold at which life transitions from dormancy to vigorous action, illuminating the ancient Way of bending and stretching to preserve one's being.
