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 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 paper examines the physical underpinnings of pre-Qin theories of *qi*, positing *qi* as a unified abstraction of matter, energy, and information. By analyzing texts such as those by Zhuangzi and Laozi, it reveals a cognitive revolution within pre-Qin thought, transitioning from mysticism towards naturalistic rationality and redefining the core value and scientific significance of *qi* in cosmology and life sciences.

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.
