'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 focuses on the core political discourses in the Xianwen chapter of the Analects concerning Zang Wuzhong, Guan Zhong, Duke Ling of Wei, and others, analyzing Confucius's profound insights on ruler-minister relations, the distinction between hegemony and kingship, and the weighing of humaneness against righteousness — particularly the chasm between 'the difficulty of action' and 'the essence of humaneness (ren).'

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.

Drawing on pre-Qin Confucian and Daoist philosophy, etymology, astronomy, phenology, and the legend of Cangjie's invention of writing, this article offers an in-depth reading of the Guyu (Grain Rain) solar term. It examines the humane grace of Heaven and Earth embodied in "rain giving birth to the hundred grains," the firm-yet-yielding way of hexagram Guai's "resolving away the last remnant of yin," and the profound meaning behind "Heaven rained down millet, and ghosts wept in the night" at the origin of writing—returning readers to the ancient world of the unity of Heaven and humanity.
