典故 · 天干口诀

天干五合口诀:甲己合化土,乙庚合化金,丙辛合化水,丁壬合化木,戊癸合化火。

天干四冲:甲庚冲,乙辛冲,丙壬冲,丁癸冲(戊己土居中不冲)。

天干五合与冲克:阴阳交感之理

十天干之间最重要的关系是"天干五合"和"天干相冲"。五合是阳干与阴干之间的特殊配对:甲己合化土、乙庚合化金、丙辛合化水、丁壬合化木、戊癸合化火。五合体现了阴阳交感、异性相吸的自然法则。

天干相冲是位置对冲的关系:甲庚冲、乙辛冲、丙壬冲、丁癸冲(戊己居中不冲)。相冲的两干五行相同但阴阳不同,代表正面对抗。此外天干还有生克关系,遵循五行相生相克的基本规律:木生火、火生土、土生金、金生水、水生木;木克土、土克水、水克火、火克金、金克木。

在八字命理中,天干透出代表"明"的力量,容易被外界感知;天干之间的合与冲直接影响格局的成败与十神的力量变化。天干五合在合婚中也常被用作判断夫妻缘分的参考之一。

常见问题

Q1天干五合"合化"是什么意思?

"合化"指两干相合后,可能转变成所化之五行。如甲己合化土,合化成功后甲和己都具有土的属性。但合化需要条件(月令、周围环境支持),并非一合就化。合而不化时,两干互相牵绊,力量减弱但不变性。

Q2天干合化成功的条件是什么?

传统命理认为合化需满足:① 所化之五行得月令(即当令)或得到其他干支的强力支持;② 两干紧贴(相邻);③ 不被其他天干争合或冲破。不同学派对合化条件有争议,但月令为最关键因素是共识。

Q3天干克与地支冲有什么区别?

天干克是五行层面的制约(如金克木),主外在、直接的矛盾;地支冲是方位对冲(如子午对冲),主暗中、持续的变动。天干之事显于外、应于近,地支之事隐于内、应于远。实际分析中需天干地支综合考量。

The Beauty of the Three Dynasties Condensed into a Single Chapter: A Deep Interpretation of "Yan Yuan Asking about Governing the State" in the Analects of Confucius, Weilinggong

This article provides a rigorous analysis of the "Yan Yuan wen weibang" passage in the *Analects*, examining Confucius’s political pedagogy—centered on the calendar of the Xia, the carriage of the Shang, the ceremonial cap of the Zhou, and the music of Shao—as a synthesis of the essential wisdom of the Three Dynasties. By situating these practices within the broader framework of Confucian statecraft, the study elucidates the idealized civilizational paradigm of the tradition and the enduring philosophical significance of its transmission.

Rising Together to the Ranks of Lords: Innate Equality and the Pre-Qin Vision of Self-Cultivation, Compared with Western Freedom and Equality

Starting from a brief episode in the Analects, in which the noble Wenzi of Wei promotes his own household steward, Zhuan, to stand alongside him among the lords, this essay reads that small event against the great declarations of freedom and equality since the Renaissance: the West places its ideal at the starting line, while the pre-Qin thinkers built the ideal into lived reality.

Dwelling, One Observes the Images; Acting, One Observes the Changes -- Reading the Chapter "The Sage Established the Hexagrams and Observed the Images" from the Upper Xici

A line-by-line reading of the second chapter of the Upper Xici. The sage's four acts -- establishing the hexagrams, observing the images, appending the statements, clarifying fortune and misfortune -- run in exact reverse order to the noble person's four acts -- observing the images, savoring the statements, observing the changes, savoring the divination. The four clauses "is the image of..." form a chain tracing effect back to cause; "the repose in which he dwells" echoes the Doctrine of the Mean's "dwelling in ease, awaiting the Mandate"; and the chapter closes by quoting the top line of hexagram Da You, "From Heaven comes its aid," gathering the whole into the two words compliance and good faith. Grounded in Confucian and Daoist thought, and drawing on the Analects, Mencius, Laozi, Zhuangzi, Xunzi, and the Zuo Tradition, it explores how the noble person finds repose between Heaven and Earth and acts amid change.

The Mystic Pivot of Earthly Order: A Study on the Ancient Origins of the Six Combinations and Qi Transformations of the Twelve Earthly Branches

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.

An In-Depth Interpretation of 'Yi' from the Greater Odes of the Classic of Poetry: Admonition and Self-Vigilance in the Pre-Qin Perspective

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.

Spirits and Sincerity in the Zhongyong: The Metaphysical Foundation and Manifestation of the Dao-Substance

This article offers an in-depth reading of the chapters on 'the virtue of ghosts and spirits' and 'sincerity is self-completing' in the Zhongyong, exploring their significance as the core of Confucian metaphysics. Through an analysis of pre-Qin conceptions of ghosts and spirits, it demonstrates that the chapter on spirits serves to prove that 'sincerity cannot be concealed,' and further elucidates how the substance of cheng (sincerity) matches Heaven and supports all things, revealing the ontological foundation of the Doctrine of the Mean.
