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.'

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 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 focuses on the opening chapter of the Guiguzi, 'Enriching the Spirit by Emulating the Five Dragons' (Sheng Shen Fa Wu Long), offering exegesis and critical analysis of the original text from a Pre-Qin perspective, drawing upon texts no later than the two Han dynasties. It explores the meaning of 'enriching the spirit,' the cosmogony of Dao and Qi, the distinction between the True Person and the Sage, and the inner connections among method, spirit, mind, and vital breath, aiming to reveal this chapter's scholarly value as the programmatic foundation of the entire Guiguzi.

This article provides an in-depth analysis of the "Zigong asks about achieving ren" passage from the *Analects' Gongye Chang* chapter. It critically examines the relationship between the aphorism "A craftsman wishing to do his work well must first sharpen his tools" and the socio-ethical environment, exploring Zigong's cultivation as a "tool" and revealing Confucian methodology for practicing *ren* within concrete socio-political relations, offering guidance for practical personalities.
