This article offers an in-depth reading of the opening core text of Xunzi's Discourse on Ritual (Lilun), systematically analyzing the logical chain by which ritual arises from human desire and social conflict, elucidating the structural vision of 'honoring the root is called pattern; cleaving to function is called order,' and exploring the graduated levels of abundance, reduction, and the middle course in ritual, together with the Way of the noble person.

An in-depth analysis of the philosophical core, the detailed procedure of the Four Operations and Eighteen Transformations, and the mathematical mysteries of non-uniform probability in the Yijing's Great Expansion milfoil divination method, combined with the classic case of Duke Mu of Qin's campaign against Jin from the Zuo Zhuan (Duke Xi, Year 15) to reconstruct the hexagram-interpretation logic of the pre-Qin perspective.

This article offers a deeply layered reading of Cold Dew (Hanlu) from the perspectives of pre-Qin Confucian and Daoist philosophy, the original meanings of Chinese characters, astronomy and phenology, and the Double Ninth chrysanthemum festival. It examines the gradual shift of dew from 'white' to 'cold,' the principle of reversal at the extremity of decline embodied in the Bo hexagram's five yin lines stripping away yang yet preserving the 'great fruit uneaten,' the gentleman's integrity symbolized by chrysanthemums defying autumn frost, and the ritual propriety of wild geese arriving as guests — revealing the hidden seed of renewal concealed within the stripping away of yang.

This article offers a deep reading of the core passage in the Guanzi: Neiye — 'That which can transform a single thing is called shen (spirit); that which can adapt to a single affair is called zhi (wisdom)' — systematically tracing the philosophical categories of shen, zhi, jing, qi, and dao in the pre-Qin era, elucidating their pivotal role in the cultivation of mind and character and in the Way of inner sageliness and outer kingliness, striving to recover the original intent of the ancients.

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 article offers an in-depth investigation into the pre-Qin, high-antiquity origins and inner rationale of the Six Combinations and their Qi transformations among the Twelve Earthly Branches (e.g., Zi-Chou combining to transform into Earth). Through textual examination of the Earthly Branches' origins, their connection with Jupiter's orbital cycle, the correspondences between the twelve months and the twelve sovereign hexagrams, and the spatial positioning of the four Earth-branches at the four inter-cardinal directions, the essay reveals the profound astronomical and yin-yang philosophical underpinnings of the Earthly Branch system as a cornerstone of Chinese metaphysical arts.
