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 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.

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.

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.

This article offers an in-depth philological investigation of the passage from the Xici Shangzhuan (Great Commentary on the Yijing): 'The junzi, when at rest, contemplates the images and savors the texts; when about to act, observes the transformations and savors the divination.' It restores how the pre-Qin junzi attained existential security through apprehending the 'order' (xu) of the Yi, and internalized cosmic order into personal cultivation through an attitude of aesthetic 'savoring' (wan).
