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.

'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.

This article offers an in-depth interpretation of Liqiu (Start of Autumn) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, the original meanings of Chinese characters, and astronomical-phenological perspectives. By examining the etymological roots of 'qiu' (autumn) as grain-and-fire, the astronomical coordinate of 135° solar longitude, and the image of Hexagram Pi (Standstill) from the Yijing — 'Heaven and Earth do not interact' — it reveals Liqiu as the pivotal moment when all things shift from 'growth' to 'gathering,' illuminating the virtue of Metal, the onset of solemn killing, and the ancient roots of the autumnal grief tradition.

This essay undertakes an in-depth study of the 'Yi' ode from the Greater Odes (Daya) section of the Classic of Poetry (Shijing) through the lens of pre-Qin thought. It examines the philological origins of the character 'yi' (restraint), confirms Duke Wu of Wei as its author with 'self-vigilance' as its guiding purpose, and elucidates the poem's emphasis on dignity, virtue, its critique of King Li's misgovernance, and its enduring political philosophy and moral cultivation significance.

This article offers an in-depth philological investigation of the passage from the Xici Shangzhuan (Great Commentary on the Yijing): 'The junzi, when at rest, contemplates the images and savors the texts; when about to act, observes the transformations and savors the divination.' It restores how the pre-Qin junzi attained existential security through apprehending the 'order' (xu) of the Yi, and internalized cosmic order into personal cultivation through an attitude of aesthetic 'savoring' (wan).
