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.

'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.'

This article systematically investigates the fourteenth hexagram of the Yijing, 'Fire over Heaven — Great Possession' (Huo Tian Da You), analyzing its trigram structure of Li above Qian below, elucidating the rich connotations of 'Great Possession,' and drawing upon pre-Qin literature to expound the principle of 'one yielding line in the place of honor, five firm lines responding to it' — the way of grand virtue and great enterprise — revealing its profound significance in ancient political philosophy.

This article offers a deep reading of the core proposition in the Xici Shangzhuan — 'What the junzi dwells in and finds peace in is the order of the Yi' — integrating the pre-Qin context, the Confucian scholarly lineage, and the structure of the Zhouyi to elucidate how the junzi, by embodying the Way of Heaven and Earth, takes the Yi as the foundation of settled existence, contemplates the images and savors the statements, and ultimately attains the state of 'auspiciousness with nothing unfavorable.'

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.
