'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.

A line-by-line exegesis of 'Substantiating Intent, Modeled on the Flying Serpent,' the third technique of the Seven Techniques of the Yin Tally in the Original Canon of the *Guiguzi*. Beginning from the definition 'substantiated intent is the deliberation of qi,' it traces the pathology of a hollow intent, the cultivation sequence from calming the five viscera to contemplating the Great Void, the cognitive attainment of 'knowing all under Heaven without leaving one's door,' and clarifies the image of the flying serpent through three pieces of pre-Qin evidence drawn from the *Xunzi*, *Shenzi*, and the *Great Treatise*.

From historical origins, theoretical foundations, and the compass as core instrument, to the doctrines of Eight Mansions, Sanhe, Xuankong Flying Star, and other major schools—along with comparative case studies and inter-school debates—a panoramic survey of the principle-and-qi (liqi) tradition for advanced readers.

This essay offers an in-depth reading of the passage on 'the imagery of music' (sheng yue zhi xiang) in Xunzi's 'Discourse on Music,' elucidating how musical sounds embody character-qualities that correspond to heaven, earth, and the myriad things, and situating the discussion within Master Xun's Confucian vision of transforming human nature through ritual and music.
