'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.

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.

This article offers a profoundly detailed interpretation of the Winter Solstice among the Twenty-Four Solar Terms, drawing upon pre-Qin Confucian and Daoist philosophy, etymological analysis, and astronomical calendrics. It reveals the cosmic pivot of 'yin at its extreme giving birth to yang, the return of first yang, and the beholding of heaven and earth's heart,' examines the rites of the Round Mound sacrifice to Heaven, the origin of the calendar epoch at the month of Zi, and the foundational note of the Yellow Bell pitch-pipe, guiding you through the ancient wisdom by which our forebears discerned the generative heart of heaven and earth amid the deepest darkness.

This article offers a deep reading of Major Snow (Daxue) among the twenty-four solar terms, drawing upon pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. It analyzes the etymology of 'da means flourishing — at this point snow flourishes,' examines the Hexagram of Return (Fu) with its 'single yang returning' in the zi month, and reveals the virtue of auspicious snow sealing and protecting nascent yang, along with the profound cosmology of 'supreme yin birthing yang — the heart of Heaven and Earth.'

This essay undertakes an in-depth study of the 'Yi' ode from the Greater Odes (Daya) section of the Classic of Poetry (Shijing) through the lens of pre-Qin thought. It examines the philological origins of the character 'yi' (restraint), confirms Duke Wu of Wei as its author with 'self-vigilance' as its guiding purpose, and elucidates the poem's emphasis on dignity, virtue, its critique of King Li's misgovernance, and its enduring political philosophy and moral cultivation significance.
