'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 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.

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 deeply analyzes the semantic fission of the character "ming" (命) in pre-Qin thought, tracing its evolution from divine mandate and innate nature to an active mission, demonstrating that it was not passive fatalism but rather proactive assumption of responsibility beyond cognitive horizons. By re-examining core propositions like Confucius's "knowing the mandate of Heaven," the study reveals the dynamic relationship of Heaven-human interaction in pre-Qin philosophy, showcasing the robust subjectivity and sense of mission within traditional Chinese culture.
