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.

'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.'

This article offers a thorough analysis of the core proposition in Xunzi's 'Jiebi' (Dispelling Obscurations) chapter concerning the nature of cognition: 'How does a person know$33 Through the mind. How does the mind know$34 Through xu (openness), yi (unity), and jing (stillness).' It systematically elucidates the dialectical relationship among these three concepts, their epistemological significance, and their roots in high antiquity, revealing the systematic rigor and precision of pre-Qin cognitive theory.

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 an in-depth reading of the opening core text of Xunzi's Discourse on Ritual (Lilun), systematically analyzing the logical chain by which ritual arises from human desire and social conflict, elucidating the structural vision of 'honoring the root is called pattern; cleaving to function is called order,' and exploring the graduated levels of abundance, reduction, and the middle course in ritual, together with the Way of the noble person.
