'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.

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.

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.

This article offers a deep investigation of the Hexagram Tong Ren (Fellowship with Others) from the Yijing (Book of Changes), grounded in pre-Qin Confucian and Daoist thought and archaic culture, tracing layer by layer the meanings of the hexagram image, judgment, and line statements. Through a careful analysis of the distinction between 'sameness' (tong) and 'harmony' (he), and drawing on the structural logic of the Xu Gua Zhuan (Sequence of Hexagrams), the article illuminates Tong Ren's pivotal role in the transition from obstruction to openness, revealing its primordial wisdom of seeking Great Unity within difference.

This article undertakes an in-depth exploration of the proposition 'nourishing the will by emulating the numinous turtle' (yang zhi fa ling gui) in the Guiguzi, examining the symbolic significance of the turtle in high antiquity, the wu-xi shamanic tradition, turtle-shell divination culture, ritual status, and longevity philosophy from multiple dimensions, revealing the profound philosophical thought and methodology of spiritual cultivation it embodies, and striving to restore its original meaning within the pre-Qin intellectual context.
