'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 offers a deep investigation of the Hexagram Tong Ren (Fellowship with Others) from the Yijing (Book of Changes), grounded in pre-Qin Confucian and Daoist thought and archaic culture, tracing layer by layer the meanings of the hexagram image, judgment, and line statements. Through a careful analysis of the distinction between 'sameness' (tong) and 'harmony' (he), and drawing on the structural logic of the Xu Gua Zhuan (Sequence of Hexagrams), the article illuminates Tong Ren's pivotal role in the transition from obstruction to openness, revealing its primordial wisdom of seeking Great Unity within difference.

A systematic survey of Duan-school Blind-Sect (Mangpai) fate calculation, examined through its lineage, guest-and-host framework, substance-and-function framework, structural work (gong), emptiness and solidity, the Ten Gods, image-reading methods, tomb-and-storage palaces, and timing systems — with a clearly bounded comparison to the Ziping pattern method.

This article provides an in-depth analysis of Lixia (the Beginning of Summer) through the lenses of pre-Qin Confucian and Daoist philosophy, etymological roots, and astronomical observation, elucidating its significance as the critical juncture where the cosmic momentum shifts from "birth" to "growth." By examining the evolution of the character "xia" (夏) and the movement of the star Antares, the study reveals the profound wisdom behind the ancient mandate of "respectfully bestowing the seasons" and the harmonious worldview of unity between humanity and the cosmos.
