'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 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 a deep exploration of the philosophical significance of Hexagram 37 'Jiaren' (Family) in the Zhouyi (Book of Changes), analyzing the relationship between the Wind-over-Fire trigram image and the Way of the family, and elucidating the foundational status of 'family' in ancient social structures through pre-Qin Confucian thought on 'roots' (ben) as found in Confucius, Mencius, and the Great Learning.

This article offers a multidimensional exploration of Lesser Cold (Xiaohan) from the perspectives of pre-Qin Confucian and Daoist philosophy, etymological origins, astronomical observation, and phenological reasoning. It reveals the 'firm force gradually ascending' imagery of the Lin (Approach) hexagram in the twelfth month, the wisdom of birds — wild geese turning north, magpies building nests, pheasants calling — as creatures that 'sense yang and move first.' It examines the paradox of why 'Lesser Cold is often colder than Greater Cold,' and elucidates the spirit of the La sacrifice — offering thanks to origins in the depth of winter — and the ancient cosmology of the unity of Heaven and humanity.
