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 Pinnacle of Vital Essence: A Deep Inquiry into Pre-Qin Arts of the Mind and the Way of Inner Cultivation
This article offers an in-depth interpretation of the opening discourse on the Dao in the Guanzi 'Neiye' (Inner Cultivation), analyzing the threefold nature of 'thorough and dense, broad and expansive, firm and steadfast,' its dialectical unity, and its significance for self-cultivation within the intellectual context of pre-Qin and high antiquity.
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.
A Clap of Spring Thunder: The Awakening of Life and the Way of Dormancy in the Jingzhe Solar Term
This article offers a deep reading of Jingzhe (Awakening of Insects) among the Twenty-Four Solar Terms, drawing on pre-Qin Confucian and Daoist philosophy, etymological origins, astronomy, and phenology. Through an examination of the historical renaming from 'Qizhe' to 'Jingzhe,' an analysis of how spring thunder rouses hibernating creatures, and the cosmic vision of the Zhen (Thunder) hexagram's 'the sovereign emerges from Zhen' in the Book of Changes, the essay reveals the critical threshold at which life transitions from dormancy to vigorous action, illuminating the ancient Way of bending and stretching to preserve one's being.
Aided by Heaven, Fortune Without Bound — Why the Top Nine of Dayou Is the Foremost Auspicious Line Among the Zhouyi's 384 Lines
Argued across four dimensions — the judgment text, the line's position, cross-verification between the Classic and its Commentary, and philosophical meaning — this essay shows why the top nine of Hexagram Dayou (Great Possession) stands first among the 384 lines of the Book of Changes: 'Aided by Heaven, fortune — nothing unfavorable' is the only unconditional, supreme judgment in the entire classic, while the Great Treatise, speaking in the Master's own voice, supplies the operative mechanism for attaining such fortune — 'treading on trust, cherishing compliance, and honoring the worthy.'
The Junzi's 'Dwelling in Ease and Savoring Divination' in the Xici: Restoring Pre-Qin Moral Nature and Cosmic Order
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).

This essay strips away the veneer of divinatory numerology to return to pre-Qin astronomy and cosmology, offering a rigorous investigation of the true nature of the Six Conjunctions of the Twelve Earthly Branches — Zi-Chou, Yin-Hai, Mao-Xu, Chen-You, and the rest. It focuses on the astronomical 'conjugation' essence of the Six Conjunctions, and the philosophical implications — sealing and storing, sprouting and rising, refining and transforming, revolution and change — concealed behind their 'qi transformations.'
