'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.

Drawing on pre-Qin Confucian and Daoist philosophy, etymology, astronomy, phenology, and the legend of Cangjie's invention of writing, this article offers an in-depth reading of the Guyu (Grain Rain) solar term. It examines the humane grace of Heaven and Earth embodied in "rain giving birth to the hundred grains," the firm-yet-yielding way of hexagram Guai's "resolving away the last remnant of yin," and the profound meaning behind "Heaven rained down millet, and ghosts wept in the night" at the origin of writing—returning readers to the ancient world of the unity of Heaven and humanity.

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.

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.
