母乘子曰虚邪（乘，胜也，克也），如心火热，乘脾土也。
子乘母曰实邪，如肺金燥，乘脾土也。
妻乘夫曰微邪，如肾水寒，乘脾土也。
夫乘妻曰贼邪，如肝木风，乘脾土也。
自病曰正邪，如脾土自病湿也。
五脏腑同法（各以类推）。
微、实、正、虚、贼，从微至甚也。
此亦大略之言，细而推之，各有微甚。
甲己合为“土运”甲刚木，克己柔土，为夫妇成土运。
乙庚合为“金运”乙柔木，嫁庚刚金。
丁壬合为“木运”丁阴火，配壬阳水。
丙辛合为“水运”丙阳火，娶辛柔金。
戊癸合为“火运”戊阳土，娶癸阴水。
阳刚夫为太过；阴柔妻为不及。
此其略也。凡六十四年而周甲子，其中有岁运同司天曰天府，同岁支曰岁
会，孟年同曰支德符，岁运同司地，刚为同天符，柔为同岁会。凡此二十九岁，
太过司天克之曰天刑，及年前大寒交气日，反时程与运程为夫妇曰程德符，皆非太过、不及，乃
年运之气也。申、子、辰年寅初交；巳、酉、丑年巳初交；寅、午、戌年申初交；亥、卯、未年亥初交气也。
六气为本，三阴三阳为标。
子午少阴“君火”（暑）丑未太阴“湿土”
寅申少阳“相火”（主大热）卯酉阳明“燥金”
辰戌太阳“寒水”巳亥厥阴“风木”
母亲克制儿子称为虚邪（乘，意为胜、克），例如心火过盛，克制脾土。
儿子反克母亲称为实邪，例如肺金燥气过盛，克制脾土。
妻子克制丈夫称为微邪，例如肾水寒气过盛，克制脾土。
丈夫克制妻子称为贼邪，例如肝木风气过盛，克制脾土。
自身发病称为正邪，例如脾土自身患病湿气过重。
五脏六腑的道理相同（各自依此类推）。
微、实、正、虚、贼，是从轻微到严重的程度排列。
这也是一般性的概括言论，细致地推究起来，各有轻重之分。
甲己相合化为“土运”，甲为刚木，克制己柔土，如同夫妇共同成就土运。
乙庚相合化为“金运”，乙为柔木，嫁配给庚刚金。
丁壬相合化为“木运”，丁为阴火，配壬阳水。
丙辛相合化为“水运”，丙为阳火，娶辛柔金。
戊癸相合化为“火运”，戊为阳土，娶癸阴水。
阳刚的丈夫代表太过；阴柔的妻子代表不及。
这是大略的说法。凡是六十四年完成一个甲子周期，其中有岁运与司天之气相同的称为天府，与岁支相同的称为岁会，孟年与地支德符相同的称为德符，岁运与在泉之气相同的，刚年为同天符，柔年为同岁会。凡这二十九年，太过之气被司天之气所克的称为天刑，以及在年前大寒节气交气之日，反时的气候与运气的气候形成夫妇关系的称为程德符，这些都不是太过或不及，而是当年的运气之气。申、子、辰年的寅初时刻交气；巳、酉、丑年的巳初时刻交气；寅、午、戌年的申初时刻交气；亥、卯、未年的亥初时刻交气。
六气为本，三阴三阳为标。
子午年少阴“君火”（暑）；丑未年太阴“湿土”。
寅申年少阳“相火”（主大热）；卯酉年阳明“燥金”。
辰戌年太阳“寒水”；巳亥年厥阴“风木”。
When the mother element overcomes the son element, it is called Deficient Pathogenic Factor (Xu Xie, 虚邪; "Cheng" means to overcome or suppress). For example, excessive Heart Fire (Xin Huo) overcoming Spleen Earth (Pi Tu).
When the son element counter-overcomes the mother element, it is called Excess Pathogenic Factor (Shi Xie, 实邪). For example, excessive Lung Dryness Metal (Fei Jin) overcoming Spleen Earth.
When the wife element overcomes the husband element, it is called Slight Pathogenic Factor (Wei Xie, 微邪). For example, excessive Kidney Cold Water (Shen Shui) overcoming Spleen Earth.
When the husband element overcomes the wife element, it is called Robbing Pathogenic Factor (Ze Xie, 贼邪). For example, excessive Liver Wind Wood (Gan Mu) overcoming Spleen Earth.
Disease arising from oneself is called Correct Pathogenic Factor (Zheng Xie, 正邪). For example, Spleen Earth suffering from internal Dampness (Shi).
The principles for the Five Zang Organs and Six Fu Organs are the same (each can be inferred by analogy).
Slight, Excess, Correct, Deficient, and Robbing represent a progression from mild to severe.
This is a general statement; upon detailed deduction, there are variations in severity for each.
Jia and Ji combine to form the "Earth Movement" (Tu Yun). Jia is Yang Wood, which controls Ji Yin Earth, resembling a husband and wife jointly establishing the Earth movement.
Yi and Geng combine to form the "Metal Movement". Yi is Yin Wood, marrying Geng Yang Metal.
Ding and Ren combine to form the "Wood Movement". Ding is Yin Fire, pairing with Ren Yang Water.
Bing and Xin combine to form the "Water Movement". Bing is Yang Fire, marrying Xin Yin Metal.
Wu and Gui combine to form the "Fire Movement". Wu is Yang Earth, marrying Gui Yin Water.
Yang-Gang Husband represents Excess (Tai Guo); Yin-Rou Wife represents Deficiency (Bu Ji).
This is a general overview. In every sixty-four-year cycle completing a Jiazi period, there are years where the Annual Movement coincides with the ruling Qi of Heaven (Si Tian), called Heavenly Treasury (Tian Fu); those coinciding with the Annual Branch are called Year Meeting (Sui Hui); those in the first year of a triad coinciding with the Branch Virtue are called Virtue Symbol (De Fu); those where the Annual Movement coincides with the Qi of Earth (Zai Di), Yang years are Same as Heavenly Movement (Tong Tian Fu), and Yin years are Same as Year Meeting (Tong Sui Hui). Of these twenty-nine years, if the Excess Qi is controlled by the Si Tian Qi, it is called Heavenly Punishment (Tian Xing). Also, on the day of Qi exchange at Great Cold before the new year, if the contrary seasonal climate forms a husband-wife relationship with the movement climate, it is called Cheng Virtue Symbol (Cheng De Fu). None of these are truly Excess or Deficiency, but rather the Qi of the annual movement. The Qi exchange occurs at the beginning of Yin month in Shen, Zi, Chen years; at the beginning of Si month in Si, You, Chou years; at the beginning of Shen month in Yin, Wu, Xu years; and at the beginning of Hai month in Hai, Mao, Wei years.
The Six Qi constitute the Root (Ben), while the Three Yin and Three Yang constitute the Mark (Biao).
Zi and Wu years: Shaoyin "Monarch Fire" (Shu/Summer Heat); Chou and Wei years: Taiyin "Damp Earth".
Yin and Shen years: Shaoyang "Minister Fire" (Zhu Da Re/Major Heat); Mao and You years: Yangming "Dry Metal".
Chen and Xu years: Taiyang "Cold Water"; Si and Hai years: Jueyin "Wind Wood".
