甲、己化土，乙、庚化金，丙、辛化水，丁、壬化木，戊、癸化火。
亥、子水，寅、卯木，巳、午火，申、酉金，辰、戌、丑、未土。
宫∶土（申也，土为中，为建极）。
商∶金（强也，象金性之坚强）。
角∶木（触也，阳气触动而生）。
征∶火（止也，物盛则止也）。

黄钟八十一弦，太簇七十六数，姑洗六十四数，林钟五十四数，南吕四十八数。
春∶角木；夏∶征火；长夏∶宫土；秋∶商金；冬∶羽水。
一、大运∶以本年天干化气为主。
一、主运∶春角木，夏征火，长夏宫土，秋商金，冬羽水。甲乙丙壬癸五年从太角起，太生少，少生太，
起于角；丁戊己庚辛五年从少角起，少生太，太生少，终于羽。
一、客运∶从中运起，初运太生少，少生太，每运管七十三日半，与主运俱同自大寒日始。
甲年化阳土，属太宫，逆推前生太宫者少征，生少征者太角，故甲年起太角。
乙年化阴金，属少商，上推前生少商者太宫，生太宫者少征，生少征者太角，故乙年起太角。
丙年化阳水，为太羽，推前生太羽者是少商，生少商者是太宫，生太宫者少征，生少征者太角，故丙年初
运太角。
丁年化阴木，属少角，即从少角起初运，其年客运尽同。
戊年化阳火，属太征，推前生太征者是少角，故戊年起少角。
己年化阴土，为少宫，推前生少宫者是太征，生太征者少角，故己年起少角。
庚年化阳金，属太商，推前生太商者是少宫，生少宫者太征，生太征者少角，故庚年起少角为初运。
辛年化阴水，为少羽，上推前生少羽者太商，生太商者少宫，生少宫者太征，生太征者少角，故辛年起少
角。
壬年化阳木，属太角，即起太角为初运，其年客运尽同。
癸年化阴火，属少征，生少征者是太角，故癸年起太角。

甲与己相合化为土，乙与庚相合化为金，丙与辛相合化为水，丁与壬相合化为木，戊与癸相合化为火。
亥、子属水，寅、卯属木，巳、午属火，申、酉属金，辰、戌、丑、未属土。
宫音：对应土（“宫”意为中，土居中央，为建立极则之本）。
商音：对应金（“商”意为强，象征金属性质的刚强）。
角音：对应木（“角”意为触，阳气触动而万物生发）。
征音：对应火（“征”意为止，物极必盛，盛极则止）。
羽音：对应水（“羽”意为舒，阳气回复，万物舒展）。
阳称为太，阴称为少。
黄钟律管有八十一根弦，太簇律管有七十六个数值，姑洗律管有六十四个数值，林钟律管有五十四根弦，南吕律管有四十八根弦。
春季：对应角木；夏季：对应征火；长夏：对应宫土；秋季：对应商金；冬季：对应羽水。
一、大运：以当年的天干化气为主。
一、主运：春季为角木，夏季为征火，长夏为宫土，秋季为商金，冬季为羽水。甲、乙、丙、壬、癸五年从太角开始，由太生少，由少生太，起于角音；丁、戊、己、庚、辛五年从少角开始，由少生太，由太生少，终于羽音。
一、客运：从中运开始，初运由太生少，由少生太，每运管辖七十三日半，与主运一样都从大寒日开始推算。
甲年化为阳土，属于太宫，逆推前一位生太宫者为少征，生少征者为太角，所以甲年起运为太角。
乙年化为阴金，属于少商，上推前一位生少商者为太宫，生太宫者为少征，生少征者为太角，所以乙年起运为太角。
丙年化为阳水，为太羽，推前一位生太羽者为少商，生少商者为太宫，生太宫者为少征，生少征者为太角，所以丙年初运为太角。
丁年化为阴木，属于少角，即从少角开始初运，该年的客运全部相同。
戊年化为阳火，属于太征，推前一位生太征者为少角，所以戊年起运为少角。
己年化为阴土，为少宫，推前一位生少宫者为太征，生太征者为少角，所以己年起运为少角。
庚年化为阳金，属于太商，推前一位生太商者为少宫，生少宫者为太征，生太征者为少角，所以庚年起运为少角作为初运。
辛年化为阴水，为少羽，上推前一位生少羽者为太商，生太商者为少宫，生少宫者为太征，生太征者为少角，所以辛年起运为少角。
壬年化为阳木，属于太角，即以太角为初运，该年的客运全部相同。
癸年化为阴火，属于少征，生少征者为太角，所以癸年起运为太角。

Jia and Ji transform into Earth; Yi and Geng transform into Metal; Bing and Xin transform into Water; Ding and Ren transform into Wood; Wu and Gui transform into Fire.
Hai and Zi belong to Water; Yin and Mao belong to Wood; Si and Wu belong to Fire; Shen and You belong to Metal; Chen, Xu, Chou, and Wei belong to Earth.
Gong (Palace): Corresponds to Earth ("Gong" means center; Earth resides in the central position, serving as the foundation for establishing the supreme standard).
Shang (Market): Corresponds to Metal ("Shang" means strong, symbolizing the firmness and strength of metal properties).
Jue (Horn): Corresponds to Wood ("Jue" means touch; Yang Qi stirs and generates life).
Zhi (Chariot): Corresponds to Fire ("Zhi" means stop; when things reach their peak, they stop).
Yu (Feather): Corresponds to Water ("Yu" means comfort/relaxation; Yang Qi returns, and all things expand).
Yang is termed "Tai" (Grand), and Yin is termed "Shao" (Minor).
The Huangzhong (Yellow Bell) pitch pipe has 81 strings; the Taicu (Great Cluster) pitch pipe has 76 units; the Guxian (Cleansing Pitch) pitch pipe has 64 units; the Linzhong (Forest Bell) pitch pipe has 54 strings; the Nanlü (Southern Rhythm) pitch pipe has 48 strings.
Spring: Jue Wood; Summer: Zhi Fire; Late Summer: Gong Earth; Autumn: Shang Metal; Winter: Yu Water.
1. Great Movement (Da Yun): Primarily determined by the transformed Qi of the Heavenly Stem of the current year.
2. Principal Movement (Zhu Yun): Spring is Jue Wood, Summer is Zhi Fire, Late Summer is Gong Earth, Autumn is Shang Metal, Winter is Yu Water. For the five years of Jia, Yi, Bing, Ren, and Gui, the sequence starts with Tai Jue (Grand Horn); Tai generates Shao, and Shao generates Tai, beginning with Jue. For the five years of Ding, Wu, Ji, Geng, and Xin, the sequence starts with Shao Jue (Minor Horn); Shao generates Tai, and Tai generates Shao, ending with Yu.
3. Guest Movement (Ke Yun): Begins from the Central Movement (Zhong Yun). The initial movement follows the pattern where Tai generates Shao, and Shao generates Tai. Each movement governs 73.5 days, starting from the Day of Great Cold (Da Han), identical to the Principal Movement.
In a Jia year, transforming into Yang Earth, belonging to Tai Gong (Grand Palace), reversing the generation cycle, the element generating Tai Gong is Shao Zhi (Minor Chariot), and the element generating Shao Zhi is Tai Jue. Thus, the Jia year begins with Tai Jue.
In a Yi year, transforming into Yin Metal, belonging to Shao Shang (Minor Market), looking upward, the element generating Shao Shang is Tai Gong, the element generating Tai Gong is Shao Zhi, and the element generating Shao Zhi is Tai Jue. Thus, the Yi year begins with Tai Jue.
In a Bing year, transforming into Yang Water, belonging to Tai Yu (Grand Feather), tracing back, the element generating Tai Yu is Shao Shang, the element generating Shao Shang is Tai Gong, the element generating Tai Gong is Shao Zhi, and the element generating Shao Zhi is Tai Jue. Thus, the initial movement of the Bing year is Tai Jue.
In a Ding year, transforming into Yin Wood, belonging to Shao Jue (Minor Horn), the initial movement starts directly from Shao Jue, and the Guest Movements for that year are entirely consistent with this starting point.
In a Wu year, transforming into Yang Fire, belonging to Tai Zhi (Grand Chariot), tracing back, the element generating Tai Zhi is Shao Jue. Thus, the Wu year begins with Shao Jue.
In a Ji year, transforming into Yin Earth, belonging to Shao Gong (Minor Palace), tracing back, the element generating Shao Gong is Tai Zhi, and the element generating Tai Zhi is Shao Jue. Thus, the Ji year begins with Shao Jue.
In a Geng year, transforming into Yang Metal, belonging to Tai Shang (Grand Market), tracing back, the element generating Tai Shang is Shao Gong, the element generating Shao Gong is Tai Zhi, and the element generating Tai Zhi is Shao Jue. Thus, the Geng year begins with Shao Jue as the initial movement.
In a Xin year, transforming into Yin Water, belonging to Shao Yu (Minor Feather), looking upward, the element generating Shao Yu is Tai Shang, the element generating Tai Shang is Shao Gong, the element generating Shao Gong is Tai Zhi, and the element generating Tai Zhi is Shao Jue. Thus, the Xin year begins with Shao Jue.
In a Ren year, transforming into Yang Wood, belonging to Tai Jue (Grand Horn), it starts with Tai Jue as the initial movement, and the Guest Movements for that year are entirely consistent with this.
In a Gui year, transforming into Yin Fire, belonging to Shao Zhi (Minor Chariot), the element generating Shao Zhi is Tai Jue. Thus, the Gui year begins with Tai Jue.
