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.'

A line-by-line exegesis of the second of the Seven Techniques in the *Basic Scripture of the Hidden Tally* section of the *Guiguzi* — 'Nurturing Aspiration, Modeled on the Sacred Tortoise.' Taking 'aspiration is the envoy of desire' as its diagnosis of pathology and 'when heart-qi is unified, desire no longer wanders' as its chain of cure, the essay draws on the *Book of Changes*, *Book of Documents*, *Book of Songs*, *Zuo Tradition*, *Analects*, *Laozi*, *Zhuangzi*, *Mencius*, *Guanzi*, and *Xunzi* to restore, within its Pre-Qin context, the original meaning of nurturing aspiration, understanding others, and the threefold virtue of the sacred tortoise.

Approaching the subject from the standpoint of pre-Qin Confucianism, this article examines the origin, essence, and civilizational foundations of ritual propriety (li), seeking to understand the profound meaning it carries between human ethical order and the Way of Heaven.

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.
