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 offers a philological and philosophical examination of the Qingming solar term, exploring the cosmic significance and humanistic ideals embodied in the concepts of "clarity" (qing) and "luminosity" (ming). Through a comprehensive analysis of its dual nature as both a seasonal juncture and a cultural festival, the study elucidates the traditional worldview of the unity of man and nature, revealing the profound reflections within Chinese civilization on life, death, and ethical order.

This article offers an in-depth interpretation of Lichun (the Beginning of Spring), the first of the Twenty-Four Solar Terms, through the multiple lenses of pre-Qin Confucian and Daoist philosophy, philology, and astronomical phenomenology. By tracing the origin of the character "chun" (萅), the image of the three yang lines ascending in the Tai hexagram, and the mythic archetype of the wood spirit Goumang, it reveals the profound significance of Lichun as the node of the year's beginning and the origination of all things, returning readers to the ancient world of the ancestors' communion between Heaven and humanity.

This article offers a multi-dimensional exploration of the Spring Equinox (Chunfen) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, the original meanings of Chinese characters, and astronomical phenomena. By analyzing the character 'fen' (divide/equalize), the sun's alignment with the equator, and seasonal signs such as the return of swallows and the onset of thunder, it reveals the profound wisdom of 'central harmony' and the unity of Heaven and humanity embedded in the equinox's equal days and nights.
