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.

'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.'

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 profoundly detailed interpretation of the Winter Solstice among the Twenty-Four Solar Terms, drawing upon pre-Qin Confucian and Daoist philosophy, etymological analysis, and astronomical calendrics. It reveals the cosmic pivot of 'yin at its extreme giving birth to yang, the return of first yang, and the beholding of heaven and earth's heart,' examines the rites of the Round Mound sacrifice to Heaven, the origin of the calendar epoch at the month of Zi, and the foundational note of the Yellow Bell pitch-pipe, guiding you through the ancient wisdom by which our forebears discerned the generative heart of heaven and earth amid the deepest darkness.

This essay strips away the veneer of divinatory numerology to return to pre-Qin astronomy and cosmology, offering a rigorous investigation of the true nature of the Six Conjunctions of the Twelve Earthly Branches — Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, and the rest. It focuses on the astronomical 'conjugation' essence of the Six Conjunctions, and the philosophical implications — sealing and storing, sprouting and rising, refining and transforming, revolution and change — concealed behind their 'qi transformations.'

This article provides a rigorous analysis of the "Yan Yuan wen weibang" passage in the *Analects*, examining Confucius’s political pedagogy—centered on the calendar of the Xia, the carriage of the Shang, the ceremonial cap of the Zhou, and the music of Shao—as a synthesis of the essential wisdom of the Three Dynasties. By situating these practices within the broader framework of Confucian statecraft, the study elucidates the idealized civilizational paradigm of the tradition and the enduring philosophical significance of its transmission.
