'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.

This article offers a deep reading of the core passage in the Guanzi: Neiye — 'That which can transform a single thing is called shen (spirit); that which can adapt to a single affair is called zhi (wisdom)' — systematically tracing the philosophical categories of shen, zhi, jing, qi, and dao in the pre-Qin era, elucidating their pivotal role in the cultivation of mind and character and in the Way of inner sageliness and outer kingliness, striving to recover the original intent of the ancients.

This article offers an in-depth interpretation of Xiaoman (Grain Full), one of the twenty-four solar terms, drawing on pre-Qin Confucian and Daoist philosophy, philology, astronomy, and phenology. Through the etymology of "full yet not overflowing," and the phenological signs of bitter herbs flourishing and wheat's autumn arriving, it reveals the deep meaning behind why the twenty-four solar terms include a "small fullness" (Xiaoman) but no "great fullness"—illuminating the ancient Chinese wisdom of guarding against excess, prizing humility, of loss following fullness and gain following modesty, of completeness found even in imperfection, and the venerable cosmology of the unity of Heaven and humanity.

A complete study of the *Zhengming* (Rectification of Names) chapter of the *Xunzi*. It takes up the Master's chain—"if names are not rectified, speech does not flow"—and opens onto the distinction between names having no fixed appropriateness and names having a fixed goodness; it traces in detail the boundary of convention-becoming-custom, the Heavenly Faculties' sorting of categories and the mind's verifying cognition, the three delusions and the inevitability of disputation, the three grades of speech, how order and disorder lie in what the mind approves, the Way as the true balance across past and present, and ends with "the self enslaved to things" and "valuing the self and putting things to service." It takes Confucian and Daoist principle as its foundation, drawing on the *Analects*, *Mencius*, *Doctrine of the Mean*, *Laozi*, *Zhuangzi*, *Zuo Tradition*, and the *Book of Songs*.
