歌曰∶甲己之年丙作首，乙庚之岁戊为头，丙辛更向庚寅起，丁壬又寅顺流行，戊癸建从何
位起，正月须向甲寅求。
歌曰∶甲己还生甲，乙庚丙作初，丙辛从戊子，丁壬庚子居，戊癸逢壬子，顺数不差殊。
假令戊子年五月，正月建甲寅，五月戊午月建，日亦同也。
凡初之气，自年前十二月大寒中气日交当年初之气分，主六十日，余八十七刻半，至春分前
六十日而有奇。自斗建丑正至卯之中，木之位，风之分也。天度至此，风气乃行，天地神明号令

辰戌之岁，阳明居之，为温凉不时。二之气，大凉乃至，民乃惨，草乃遇寒，火气遂折，
民病郁，中满，寒乃始，自凉而又之于寒，故寒气始于来近人也。
巳亥岁，太阳居之，为寒雨，间热。二之气，寒不去，华霜雪，水冰，杀气施化，霜乃降，
名草上焦，寒雨数至，阳复藏，民病热于中。
凡三之气，自小满中气日交入三之气分，终于六十日，余八十七刻半，至大暑前六十日而有
奇。自斗建巳正至未之中，三之气分，相火之位也，夏至前后各三十日也，少阳之分也。天度之
此，炎热大行。
子午岁，少阴居之，为大暑，亢，民病热。三之气，天政布，火大行，应物蕃鲜，寒气时，
民病气厥心痛，寒热更作，咳喘目赤。

卯酉岁，阳明居之，为凉气向发。三之气，天政布，燥气行，热交合，燥极而泽，民病寒热而疟也。

反热中，痈疽，注
下，心热瞀闷，不治者死，当寒反热是也。反天常，热起于心，神之危极，不急扶救，神乃消亡，
故治则生，不治则死。
巳亥岁，厥阴居之，为风热大行，雨化羽虫。三之气，天政布，风乃时举，民病泣出，耳鸣，掉眩。
凡四之气，自大暑中气日交入四之气分，终于六十日，余八十七刻半，至秋分前六十日而有
奇。自斗建未正至酉之中，土气治之，雨之分也。天度至此，云雨大行，湿热蒸乃作。
子午岁，太阴居之，为大雨霪。四之气，溽暑至，火行，寒热至，民病寒热，嗌干，黄胆，

凡五之气，自秋分中气日交入五之气分，终于六十日，余八十七刻半，至小雪前六十日而有
奇。自斗建酉正至亥之中，五之气分，金气治之，燥之分也，之此万物穷燥。

故万物舒荣。
巳亥岁，太阴居之，为时雨沉阴。五之气，燥湿更胜，沉阴乃布，寒气及体，风雨时行。
凡六终之气，自小雪中气日交入六之气分，终于六十日，余八十七刻半，至大寒前六十日而
有奇。自斗建亥正至丑之中，终尽天之气，水气治之，寒之分也。天度至此，寒气大行。
子午岁，阳明居之，为燥寒行。终之气，燥令行，余火内格，病肿于上，咳喘，甚则血溢。
寒气数举，则雾
露雨，瞀翳，病生及腠内，舍于胁下，连少腹，而作寒中，地博易也，气胜则可长也。
丑未岁，太阳居之，为大凝冽。终之气，大寒举，湿大化，霜乃积，阴乃凝，冰坚，阳光

出见，流水不冰，地气大发，草乃生，人乃舒，其病湿厉。
凡此上文，每一主位之内，有主客气耳。是以此为其法也，始于子年，终于亥年。每一岁
之中，常以六位矣，气在其下，地应阴，静而位永定不易，岁岁皆然。天之气，动而不息，居无
常之位，随其岁气交移，则司天为三之气，地为终之气。左右之间气也，地之左间为初之气，右
间为五之气，天之左间为终气，右间为二之气，所谓客气也。
客行则在主之上，主在客之下。上下相召，寒暑相临，阴阳相错，而变由生也。
凡此之言人，是以犯其天纲，微微而有异也。先立天地盈虚，以明岁运之太少，及更以别其
盛衰，推六步之临御，适其分野，得而推之，察其得遇，可以其用也。
（新添）夫天之六气阴阳者，动而不息，以轮流而于六矣。主位之上，常以当岁之气，便
为司天，而为三气相火之客也，后三气，便为在泉之气之客也。其司天气者，有南北二政也。甲
己土运，乃南政司天，土独尊，其余金水火木，皆北政。南政者，顺天而转，定左右间气也。假
令甲子年，南政司天，子午乃少阴，君火之上，为司天也。中太宫，土运。下进三位，卯位，甲
与己合，乃己卯司地也。司天气者，两相近者，为间气也。子为司天，少阴君火也，亥乃厥阴风
木也，为右间气，丑，太阴湿土，为左间气也，卯，阳明燥金，为司地，寅，少阳相火，为左间
气，辰，太阳寒水，为右间气也。
一年移一位，以至六居而还会矣。然上下相临，阴阳相错，而变由生也。气相得则和，不
相得则病，主胜客则客病，而为逆也，客胜主则主病，而为顺也。主客之胜，而无复也，所为三
阴三阳自有盛衰之理也。寅申巳亥为一阴一阳，子午卯酉为二阴二阳，辰戌丑未为三阴三阳，以
义推之，而知盛衰之变异也。
\r旧经南政司天之图\pt166a17.bmp\r
歌曰∶岁辰之气是司天，（岁谓年也，辰为支也，则知子午岁少阴君火司天之理也，则知子午
之左进一位至丑年，每年到，便为司天气也。）左进三辰为在泉。（进三辰，至卯酉，阳明在泉
之类也。）天皆南面言左右，（司天位在南，而北面言其左右之间气也。）北地左右面南言。（司
地位在北，而南面言其左右之间气也。）司天便为三气客，（司天者，上也，南北二政皆司天，
为之气，便是三之气，客也。）地为终气必应然。（司地者，一名在泉，所谓下也，乃为终之气，
客也。）地左间居
终之气，（司地左间为终之气，客也，司地右间为四气，客也，司天居三气，客也。）欲知地
气自排连。（四气司天，右间居二气，司地终气同，而别推之也。）

司天六元真气者，每一岁前三气在天，后三气在地也。其六气，二气在天地之间，余四气在
间气也。司天之气者，主岁半之前，三气也，其在泉者，主岁半之后，也三。谓司天正主三之气
分也，乃是至后。合三十日，余四十三刻七十五分也。余四间气者，为天地阴阳所行
之道路，而各主六十日，余八十七刻半也。然总之六步，则为三百六十五日一十五刻，乃成一岁耳。

夫五运者，每一岁通主一期，而五为为一周也。以随乎一运主一岁，而太少相次也。然一岁
之中，亦有五运，而合主一岁也。凡此五运，元于之主所，以木火土金水而相袭治之也。常以木
为初运，各随年前交初气之日，时刻皆同。次木生火为二之运，次春分后十三日交。次火生土为
三之运，次小满日后二十五日交。次土生金为四之运，次大暑后三十七日交。次金生水为五之运，
次秋分后四十九日交。终而复始也。凡一运，七十三日五刻，总之为一期。（此乃五运主客者。
前各有运策加临，易见也。）或云岁中
五运，各有主客，当以主客也。以年干前二干为初运之客，而以（因。）五运上下加临，（其年干
前二干为客运者，具载《玉册》内。按∶六元正纪大论曰∶天运便为初运也。）而为燥者，误也。
然司天者在其上，司地者在其下，岁运者在其中。常以般运天地之气，而为升降。又，六步主客
之气者，客气在上，主气在下，岁中天运在其中，而般运上下主客之气，而升降也。凡此皆是三
才之道也，乃自然之理，造化物之由也。一生二，二生三，三生万物矣，安得有主客之气，反无
以般之耶，宜为谬矣。运有太少者，但同岁运之太少，
上下太少相因可知。谬以阳年先起太角，阴年先起少角者，非也。（前太少角图，载法在前，与经同也。）

歌诀说：甲年和己年，正月从丙寅开始；乙年和庚年，正月从戊寅开始；丙年和辛年，从庚寅开始；丁年和壬年，也从寅月开始顺行；戊年和癸年，正月应从甲寅开始。
另一首歌诀说：甲年和己年，正月是甲寅；乙年和庚年，正月是丙寅；丙年和辛年，正月是戊寅；丁年和壬年，正月是庚寅；戊年和癸年，正月是壬寅，顺着数去没有差错。例如戊子年的五月，正月建甲寅，五月就是戊午月，日干支的推算也是同样的道理。
凡是初之气，从前一年的十二月大寒节气的中气时刻交接进入当年的初之气阶段，主管六十天零八十七刻半，到春分前六十多天结束。此时北斗斗柄指向丑正至卯中之间，这是木的位置，风的主令范围。天体运行至此，风气开始盛行，这是天地神明号令的开始，是天意的驱使，天气加临于地。
子年和午年，太阳寒水司天（作为初之气的客气），表现为寒冷，霜雪凛冽，水结冰。初之气时，气候变迁，暑热将去，寒气始生，冬眠的虫子重新藏伏，水结成冰，霜再次降落，风势猛烈，人体阳气郁结，民众需要严密保暖，关节僵硬固着，腰部疼痛。随着炎热暑气即将兴起，内外易发生疮疡。
丑年和未年，厥阴风木司天，表现为大风使万物萌发而毛气下降。初之气时，地气变迁，寒气消退，春气正当令，风开始吹拂并滋生，和气散布化育，万物繁荣，这叫做舒气。若风湿相互搏结，雨水复降，民众易患血溢、筋络拘挛强直、关节不利、身体沉重、筋脉痿软等病。
寅年和申年，少阴君火司天，表现为热风伤人，时行疫病流行。初之气时，地气变迁，风胜则摇动，寒气变得过于温暖，草木早早繁荣，寒气来而不杀伐，温病于是兴起。其病症表现为气逆于上，吐血、目赤、咳嗽气逆、头痛、崩漏、胁痛、皮肤腠理间生疮。
卯年和酉年，太阴湿土司天，表现为风雨凝结，寒气不散。初之气时，地气变迁，阴气开始凝结，气候开始肃杀，水结成冰，寒雨化生，其病症为内热，面目浮肿，鼻塞流涕或出血，打喷嚏，呵欠，呕吐，小便黄赤，严重则出现淋证。
辰年和戌年，少阳相火司天，表现为温热，易发瘟疫。初之气时，地气变迁，火气变暖，草早早繁荣，民众易患疠疫，暑气发作，身体发热，头痛，呕吐，肌肤腠理生疮，出现赤斑。
巳年和亥年，阳明燥金司天，表现为清风雾露朦胧昏暗。初之气时，气候开始肃杀，寒气刚至，民众易患寒风引起的疾病，时常发作咳嗽，左右胁下疼痛。
凡是二之气，从春分节气的中气时刻交接进入二之气阶段，终于六十天零八十七刻半，到小满前六十多天结束。此时北斗斗柄指向卯正至巳中之间，这是二之气的阶段，君火的位置，称为少阴，是热的主令范围。天体运行至此，温和的火气盛行，君火主热但不行炎暑之令，这是君位的德行。
子年和午年，厥阴风木在泉（作为二之气的客气），表现为风湿雨，化生羽虫。二之气时，阳气布散，风开始吹行，春气已尽，万物应时繁荣，寒风清冷，民众平和，其病症为眼睛昏花，赤色热气郁结于上部而发热。
丑年和未年，少阴君火在泉，为天正舒荣，因其得位，君令宣行故也。二之气时，火气正旺，万物繁荣，水化气乃和，其病症为温疠火行，远近皆然，湿蒸相互搏结，雨水按时降下，顺应天道常规，称为时雨。
寅年和申年，太阴湿土在泉，表现为时雨。二之气时，湿气郁入阴分。白埃四起，云趋雨府，风不胜湿，雨滴落下，民众安康，其病症为热郁于上，咳嗽气逆呕吐，疮发于中，胸膈咽喉不利，头痛，身体发热昏愦，脓疮。
卯年和酉年，少阳相火在泉，表现为潜逆，火热时行，疫疠乃生。二之气时，阳气布散，民众舒畅，树木生长繁荣，但疠疾大至，民众容易突然死亡，这是因为君居臣位，臣居君位（君居臣位如壬午年，臣居君位如甲子年）的缘故。
辰年和戌年，阳明燥金在泉，表现为温凉不时。二之气时，大凉之气到来，民众感到凄惨，草木遭遇寒冷，火气被折损，民众患病郁闷，腹部胀满，寒气始生，由凉转寒，所以寒气开始侵袭人。
巳年和亥年，太阳寒水在泉，表现为寒雨，间有热象。二之气时，寒气不去，华霜雪，水结冰，杀气施化，霜降落，名草受焦，寒雨频繁到来，阳气重新藏伏，民众患病体内热。
凡是三之气，从小满节气的中气时刻交接进入三之气阶段，终于六十天零八十七刻半，到大暑前六十多天结束。此时北斗斗柄指向巳正至未中之间，是三之气的阶段，相火的位置，夏至前后各三十天，是少阳的分野。天体运行至此，炎热盛大盛行。
子年和午年，少阴君火在泉（作为三之气的客气），表现为大暑，亢盛，民众患病热。三之气时，天政布散，火气大行，应物繁盛鲜艳，寒气偶尔至，民众患病气厥心痛，寒热交替发作，咳嗽气喘，目赤。
丑年和未年，太阴湿土在泉，表现为云雨雹。三之气时，天政布散，湿气降，地气胜，雨水按时降下，寒气随之而来，感受寒湿，则民众患病身体沉重肿胀，胸部胀满。
寅年和申年，少阳相火在泉，表现为暴热至，草萎槁干，炎光，湿化晚布。三之气时，天政布散，暑气至，少阳临上，雨停止，民众患病热中，耳聋，眼花，血溢脓疮，咳嗽，呕吐，鼻塞流涕或出血，打喷嚏，目赤，突然死亡。
卯年和酉年，阳明燥金在泉，表现为凉气向发。三之气时，天政布散，燥气行，热交合，燥极而泽，民众患病寒热往来如疟疾。
辰年和戌年，太阳寒水在泉，表现为寒气间至，热争冰雹。三之气时，天政布散，寒气行，雨降下，民众患病寒，反见热中，痈疽，泄泻，心热瞀闷，不治疗会死，这就是当寒反热的情况。违背天道常规，热起于心，神危极，不紧急扶救，神会消亡，所以治疗则生，不治疗则死。
巳年和亥年，厥阴风木在泉，表现为风热大行，雨化羽虫。三之气时，天政布散，风按时起，民众患病流泪，耳鸣，抖动眩晕。
凡是四之气，自大暑节气的中气时刻交接进入四之气阶段，终于六十天零八十七刻半，到秋分前六十多天结束。此时北斗斗柄指向未正至酉中之间，是土气治事，雨的主令范围。天体运行至此，云雨大行，湿热蒸腾作。
子年和午年，太阴湿土在泉（作为四之气的客气），表现为大雨连绵。四之气时，溽暑至，火行，寒热至，民众患病寒热，咽干，黄疸，鼻塞流涕或出血，饮邪发作，腹部胀满。
丑年和未年，少阳相火在泉，表现为炎热怫胜，云雨冰雹。四之气时，畏火临，溽暑蒸化，地气腾，天气痞隔，寒风晚暮，蒸热相搏，草木凝烟，湿化不流，则白露阴布以秋令，万物得之以成，民众患病腠理热，血间溢，疟疾，心腹满，胞胀，严重则水肿。
寅年和申年，阳明燥金在泉，表现为清雨雾露。四之气时，凉气至，炎暑间化，白露降，民众平和，突然发病，腹部胀满，浮肿。
卯年和酉年，太阳寒水在泉，表现为寒雨害物。四之气时，雨降，民众患病突发，战栗谵妄，少气，咽干引饮，反厥心痛，痈肿疮疡，忽发寒疾，骨痿，便血。
辰年和戌年，厥阴风木在泉，表现为暴风雨摧拉，而生裸虫。四之气时，风湿交争，风化为雨，物之乃长乃化乃成，民众患病大热少气，肌肉痿，泄泻赤白。
巳年和亥年，少阴君火在泉，表现为寒热气反，山泽浮云，暴溽蒸。四之气时，溽暑湿薄争于左之上，民众患病黄疸，而为水肿。
凡是五之气，从秋分节气的中气时刻交接进入五之气阶段，终于六十天零八十七刻半，到小雪前六十多天结束。此时北斗斗柄指向酉正至亥中之间，是五之气的阶段，金气治事，燥的主令范围，至此万物穷燥。
子年和午年，少阳相火在泉（作为五之气的客气），表现为湿为清使政，万物乃荣。五之气时，畏火临，暑乃至，阳乃化，万物乃长乃荣，民众安康，其病症为温病。
丑年和未年，阳明燥金在泉，表现为大凉燥疾。五之气时，惨令以行，寒露下，霜早降，草木黄落，寒气及体，君子周密，民众患病皮肤腠理不适。
寅年和申年，太阳寒水在泉，表现为早寒。五之气时，阳乃去，寒乃来乘，气门乃闭，刚木凋，民众避邪气，君子周密。
卯年和酉年，厥阴风木在泉，表现为凉风大行，雨生介虫。五之气时，春令乃行，草乃生荣，民众气和。
辰年和戌年，少阴君火在泉，表现为秋，湿病时行。五之气时，阳复化，草乃长乃化乃成，舒，大火临御，故万物舒荣。
巳年和亥年，太阴湿土在泉，表现为时雨沉阴。五之气时，燥湿更胜，沉阴乃布，寒气及体，风雨时行。
凡是六终之气，从小雪节气的中气时刻交接进入六之气阶段，终于六十天零八十七刻半，到大寒前六十多天结束。此时北斗斗柄指向亥正至丑中之间，终尽天之气，水气治事，寒的主令范围。天体运行至此，寒气大行。
子年和午年，阳明燥金在泉（作为六之气的客气），表现为燥寒行。终之气时，燥令行，余火内格，病肿于上，咳嗽气喘，严重则血溢。寒气数举，则雾露雨，瞀翳，病生及腠内，舍于胁下，连少腹，而作寒中，地博易也，气胜则可长也。
丑年和未年，太阳寒水在泉，表现为大凝冽。终之气时，大寒举，湿大化，霜积，阴凝，冰坚，阳光不治，感于寒，则关节禁固，腰痛，寒湿持于气交，而为病也。
寅年和申年，厥阴风木在泉，表现为寒风飘扬，而生鳞虫。终之气时，地气之正，风乃至，万物反生，朦雾，其病关闭不藏而咳逆。
卯年和酉年，少阴君火在泉，则蛰虫出见，流水不冰。终之气时，阳气布，候反温，蛰虫来见，流水不冰，民众安康平，其病症为温病，这是君火的化气。
辰年和戌年，太阴湿土在泉，表现为凝寒寄地，湿也。终之气时，湿令行，阴凝太虚，埃昏瞑，野昧，民众凄惨，寒风以至，反者孕死。
巳年和亥年，少阳相火在泉，表现为寒温，蛰虫不藏，流水不冰。终之气时，畏火司政，阳乃大化，蛰虫出见，流水不冰，地气大发，草乃生，人乃舒，其病症为湿厉。
以上文字中，每一主位之内，有主客气之分。因此以此作为法则，始于子年，终于亥年。每一年中，常有六位，气在下，地应阴，静而位永定不易，岁岁皆然。天的气，动而不息，居无常之位，随其岁气交移，则司天为三之气，地在泉为终之气。左右之间气也，地的左间为初之气，右间为五之气，天的左间为终气，右间为二之气，所谓客气也。
客气行则在主之上，主在客之下。上下相召，寒暑相临，阴阳相错，而变由生也。
以上所言于人，是以犯其天纲，微微而有异也。先立天地盈虚，以明岁运之太少，及更以别其盛衰，推六步之临御，适其分野，得而推之，察其得遇，可以其用也。
（新添）天的六气阴阳，动而不息，轮流于六步。主位之上，常以当岁之气，便为司天，而为三气相火之客也，后三气，便为在泉之气之客也。其司天气者，有南北二政也。甲己土运，乃南政司天，土独尊，其余金水火木，皆北政。南政者，顺天而转，定左右间气也。假令甲子年，南政司天，子午乃少阴，君火之上，为司天也。中太宫，土运。下进三位，卯位，甲与己合，乃己卯司地也。司天气者，两相近者，为间气也。子为司天，少阴君火也，亥乃厥阴风木也，为右间气，丑，太阴湿土，为左间气也，卯，阳明燥金，为司地，寅，少阳相火，为左间气，辰，太阳寒水，为右间气也。
一年移一位，以至六居而还会矣。然上下相临，阴阳相错，而变由生也。气相得则和，不相得则病，主胜客则客病，而为逆也，客胜主则主病，而为顺也。主客之胜，而无复也，所为三阴三阳自有盛衰之理也。寅申巳亥为一阴一阳，子午卯酉为二阴二阳，辰戌丑未为三阴三阳，以义推之，而知盛衰之变异也。
歌诀说：岁辰之气是司天。（岁谓年也，辰为支也，则知子午岁少阴君火司天之理也，则知子午之左进一位至丑年，每年到，便为司天气也。）左进三辰为在泉。（进三辰，至卯酉，阳明在泉之类也。）天皆南面言左右，（司天位在南，而北面言其左右之间气也。）北地左右面南言。（司地位在北，而南面言其左右之间气也。）司天便为三气客，（司天者，上也，南北二政皆司天，为之气，便是三之气，客也。）地为终气必应然。（司地者，一名在泉，所谓下也，乃为终之气，客也。）地左间居终之气，（司地左间为终之气，客也，司地右间为四气，客也，司天居三气，客也。）欲知地气自排连。（四气司天，右间居二气，司地终气同，而别推之也。）
司天六元真气者，每一岁前三气在天，后三气在地也。其六气，二气在天地之间，余四气在间气也。司天之气者，主岁半之前，三气也，其在泉者，主岁半之后，也三。谓司天正主三之气分也，乃是至后。合三十日，余四十三刻七十五分也。余四间气者，为天地阴阳所行之道路，而各主六十日，余八十七刻半也。然总之六步，则为三百六十五日一十五刻，乃成一岁耳。
夫五运者，每一岁通主一期，而五为为一周也。以随乎一运主一岁，而太少相次也。然一岁之中，亦有五运，而合主一岁也。凡此五运，元于之主所，以木火土金水而相袭治之也。常以木为初运，各随年前交初气之日，时刻皆同。次木生火为二之运，次春分后十三日交。次火生土为三之运，次小满日后二十五日交。次土生金为四之运，次大暑后三十七日交。次金生水为五之运，次秋分后四十九日交。终而复始也。凡一运，七十三日五刻，总之为一期。（此乃五运主客者。前各有运策加临，易见也。）或云岁中五运，各有主客，当以主客也。以年干前二干为初运之客，而以（因。）五运上下加临，（其年干前二干为客运者，具载《玉册》内。按∶六元正纪大论曰∶天运便为初运也。）而为燥者，误也。然司天者在其上，司地者在其下，岁运者在其中。常以般运天地之气，而为升降。又，六步主客之气者，客气在上，主气在下，岁中天运在其中，而般运上下主客之气，而升降也。凡此皆是三才之道也，乃自然之理，造化物之由也。一生二，二生三，三生万物矣，安得有主客之气，反无以般之耶，宜为谬矣。运有太少者，但同岁运之太少，上下太少相因可知。谬以阳年先起太角，阴年先起少角者，非也。（前太少角图，载法在前，与经同也。）
The verse states: In years of Jia and Ji, the first month begins with Bing Yin; in years of Yi and Geng, it starts with Wu Yin; in years of Bing and Xin, it commences from Geng Yin; in years of Ding and Ren, it also flows sequentially from Yin; for years of Wu and Gui, the first month must be sought from Jia Yin.
Another verse states: In years of Jia and Ji, the first month is Jia Yin; in years of Yi and Geng, it is Bing Yin; in years of Bing and Xin, it is Wu Yin; in years of Ding and Ren, it is Geng Zi; in years of Wu and Gui, it is Ren Zi, counting forward without error. For example, in a Wu Zi year, if the first month is Jia Yin, the fifth month is Wu Wu; the calculation for days follows the same principle.
Regarding the First Qi (Chu Zhi Qi), it transitions from the midpoint of the Da Han (Great Cold) solar term in the twelfth month of the previous year into the First Qi of the current year, governing for sixty days plus eighty-seven and a half ke (time units), ending before the Chun Fen (Spring Equinox) by more than sixty days. At this point, the Big Dipper points from Chou Zheng to Mao Zhong, marking the position of Wood and the domain of Wind. When the celestial degrees reach here, wind qi begins to prevail, initiating the commands of Heaven and Earth deities, representing the influence of Heavenly Qi.
In Zi and Wu years, Tai Yang (Cold Water) governs as the guest qi for the First Qi, manifesting as cold, biting frost and snow, and frozen water. During the First Qi, the climate shifts; summer heat departs, cold begins, hibernating insects re-hide, water freezes, frost descends again, winds become fierce, Yang Qi becomes stagnant, people need to dress warmly, joints become stiff and fixed, and lower back pain occurs. As intense heat approaches, sores and ulcers may arise internally and externally.
In Chou and Wei years, Jue Yin (Wind Wood) governs, bringing strong winds that promote growth while reducing hair/fur qi. During the First Qi, Earth Qi shifts, cold recedes, Spring Qi becomes proper, wind arises and nurtures, harmonious Qi spreads, and all things flourish, known as "Shu Qi" (Comfortable Qi). If Wind-Dampness combats, rain returns, and people suffer from blood overflow, tendon stiffness, joint dysfunction, heavy body, and tendon flaccidity.
In Yin and Shen years, Shao Yin (Fire Fire) governs, causing wind-heat injury and epidemic spread. During the First Qi, Earth Qi shifts, wind dominance causes shaking, cold becomes excessively warm, grass and trees bloom early, cold fails to kill, and warm diseases arise. Symptoms include Qi rebellion upwards, hematemesis, red eyes, cough with rebellious Qi, headache, uterine bleeding, hypochondriac pain, and skin sores.
In Mao and You years, Tai Yin (Damp Earth) governs, causing wind and rain to condense with lingering cold. During the First Qi, Earth Qi shifts, Yin begins to congeal, Qi becomes solemn, water freezes, cold rain transforms, leading to internal heat, facial swelling, nasal congestion/epistaxis, yawning, vomiting, yellow-red urine, and severe cases of strangury.
In Chen and Xu years, Shao Yang (Ministerial Fire) governs, bringing warmth and epidemics. During the First Qi, Earth Qi shifts, Fire warms, grass blooms early, people suffer plagues, summer heat acts, causing fever, headache, vomiting, skin sores, and red macules.

Regarding the Second Qi, it transitions from the midpoint of the Chun Fen (Spring Equinox) solar term into the Second Qi phase, lasting sixty days plus eighty-seven and a half ke, ending before Xiao Man (Grain Buds) by more than sixty days. The Big Dipper points from Mao Zheng to Si Zhong, marking the Second Qi, the position of Sovereign Fire (Jun Huo), called Shao Yin, the domain of Heat. Here, gentle fire prevails; Sovereign Fire governs heat but does not act with scorching heat, reflecting its virtue.
In Zi and Wu years, Jue Yin (Wind Wood) governs below, bringing wind-damp rain and transforming feathered creatures. During the Second Qi, Yang Qi spreads, wind blows, Spring Qi ends, all things flourish, cold wind clears, people are peaceful, suffering from eye dimness and red Qi stagnation above with heat.
In Chou and Wei years, Shao Yin (Sovereign Fire) governs below, bringing natural flourishing due to proper positioning and command execution. During the Second Qi, Fire is proper, things flourish, Water transforms into Qi harmoniously, leading to warm epidemics spreading everywhere, damp steaming combats, timely rain falls, following Heaven's norm, called "Shi Yu" (Timely Rain).
In Yin and Shen years, Tai Yin (Damp Earth) governs below, bringing seasonal rain. During the Second Qi, Dampness enters Yin. White dust rises, clouds gather at the rain source, wind cannot overcome dampness, rain falls, people are healthy, but may suffer from heat stagnation above, cough/vomiting, mid-body sores, chest/throat obstruction, headache, fever, dizziness, and suppurative sores.
In Mao and You years, Shao Yang (Ministerial Fire) governs below, causing latent rebellion, intermittent hot fire, and epidemic generation. During the Second Qi, Yang spreads, people feel comfortable, wood flourishes, but plagues strike heavily, causing sudden death, because Sovereign occupies Minister's position and Minister occupies Sovereign's position (e.g., Ren Wu year: Sovereign in Minister's place; Jia Zi year: Minister in Sovereign's place).
In Chen and Xu years, Yang Ming (Dry Metal) governs below, causing irregular warmth and coolness. During the Second Qi, great coolness arrives, people feel miserable, grass meets cold, Fire Qi is broken, people suffer depression, abdominal fullness, cold begins, transitioning from cool to cold, so cold Qi attacks humans.

Regarding the Third Qi, it transitions from the midpoint of the Xiao Man (Grain Buds) solar term into the Third Qi phase, lasting sixty days plus eighty-seven and a half ke, ending before Da Shu (Great Heat) by more than sixty days. The Big Dipper points from Si Zheng to Wei Zhong, marking the Third Qi, the position of Ministerial Fire (Xiang Huo), thirty days before and after Summer Solstice, the domain of Shao Yang. Here, intense heat prevails greatly.
In Zi and Wu years, Shao Yin (Sovereign Fire) governs below, bringing great heat and hyperactivity, causing heat diseases. During the Third Qi, Heavenly Policy spreads, Fire acts largely, things flourish, cold occasionally arrives, causing Qi reversal, heart pain, alternating cold/heat, cough/wheezing, and red eyes.

In Chen and Xu years, Tai Yang (Cold Water) governs below, bringing intermittent cold and heat-clashing hail. During the Third Qi, Heavenly Policy spreads, Cold acts, rain falls, people suffer cold, but reverse to internal heat, carbuncles, diarrhea, heart heat/dizziness. Untreated, death ensues; this is when cold reverses to heat. Violating Heaven's norm, heat originates in the Heart, endangering Spirit; urgent rescue is needed, or Spirit perishes. Treatment brings life; neglect brings death.
In Si and Hai years, Jue Yin (Wind Wood) governs below, bringing rampant wind-heat and feathered creatures via rain. During the Third Qi, Heavenly Policy spreads, wind rises timely, people suffer tearing, tinnitus, tremors, and vertigo.
Regarding the Fourth Qi, it transitions from the midpoint of the Da Shu (Great Heat) solar term into the Fourth Qi phase, lasting sixty days plus eighty-seven and a half ke, ending before Qiu Fen (Autumn Equinox) by more than sixty days. The Big Dipper points from Wei Zheng to You Zhong, marking Earth Qi governance and the domain of Rain. Here, clouds and rain prevail, damp-heat steams.
In Zi and Wu years, Tai Yin (Damp Earth) governs below, bringing continuous heavy rain. During the Fourth Qi, muggy heat arrives, Fire acts, cold/heat arrive, people suffer chills/fever, dry throat, jaundice, nasal issues, fluid retention, and abdominal fullness.
In Chou and Wei years, Shao Yang (Ministerial Fire) governs below, bringing oppressive heat, clouds, rain, and hail. During the Fourth Qi, Fear of Fire descends, muggy heat steams, Earth Qi rises, Heaven Qi blocks, cold wind comes late, steaming heat combats, grass smokes, dampness stagnates, white dew spreads with Autumn command, things mature, people suffer pore heat, interstitial blood overflow, malaria, heart/abdominal fullness, bladder distension, and severe edema.
In Yin and Shen years, Yang Ming (Dry Metal) governs below, bringing clear rain, fog, and dew. During the Fourth Qi, coolness arrives, summer heat intermittently transforms, white dew descends, people are peaceful, but suddenly suffer abdominal fullness and edema.

Regarding the Fifth Qi, it transitions from the midpoint of the Qiu Fen (Autumn Equinox) solar term into the Fifth Qi phase, lasting sixty days plus eighty-seven and a half ke, ending before Xiao Xue (Minor Snow) by more than sixty days. The Big Dipper points from You Zheng to Hai Zhong, marking the Fifth Qi, Metal Qi governance, and the domain of Dryness. Here, all things face extreme dryness.
In Zi and Wu years, Shao Yang (Ministerial Fire) governs below, bringing dampness as a clear minister, things flourish. During the Fifth Qi, Fear of Fire descends, heat arrives, Yang transforms, things grow/flourish, people are healthy, but may suffer warm diseases.

In Si and Hai years, Tai Yin (Damp Earth) governs below, bringing seasonal rain and deep Yin. During the Fifth Qi, Dry/Damp alternate in dominance, deep Yin spreads, cold hits the body, wind/rain act timely.
Regarding the Sixth Qi (Final Qi), it transitions from the midpoint of the Xiao Xue (Minor Snow) solar term into the Final Qi phase, lasting sixty days plus eighty-seven and a half ke, ending before Da Han (Great Cold) by more than sixty days. The Big Dipper points from Hai Zheng to Chou Zhong, concluding Heavenly Qi, Water Qi governance, and the domain of Cold. Here, cold Qi prevails greatly.
In Zi and Wu years, Yang Ming (Dry Metal) governs below, bringing dry-cold action. During the Final Qi, Dry command acts, residual Fire is blocked internally, swelling above, cough/wheezing, severe blood overflow. Frequent cold raises fog/dew/rain, dizziness/blindness, disease arises in pores, settles in hypochondrium connecting to lower abdomen, causing internal cold. Earth is broad/easy, Qi victory allows growth.
In Chou and Wei years, Tai Yang (Cold Water) governs below, bringing great freezing. During the Final Qi, Great Cold rises, Damp transforms greatly, frost accumulates, Yin congeals, ice hardens, Sunlight fails, contracting cold causes joint stiffness, lower back pain, cold-damp holding at Qi intersection causing disease.
In Yin and Shen years, Jue Yin (Wind Wood) governs below, bringing blowing cold wind and scale-fish. During the Final Qi, Earth Qi is proper, wind arrives, things reverse birth, mist/fog, disease involves closed gates failing to store and cough/rebellious Qi.
In Mao and You years, Shao Yin (Sovereign Fire) governs below, hibernating insects appear, flowing water does not freeze. During the Final Qi, Yang Qi spreads, climate reverses to warm, insects appear, water doesn't freeze, people are healthy/peaceful, suffering warm diseases, due to Sovereign Fire transformation.

In Si and Hai years, Shao Yang (Ministerial Fire) governs below, bringing cold-warmth, hibernating insects do not hide, water doesn't freeze. During the Final Qi, Fear of Fire governs policy, Yang transforms greatly, insects appear, water doesn't freeze, Earth Qi erupts, grass grows, people feel comfortable, suffering damp febrile diseases.
In the above text, within each Principal Position, there are Principal and Guest Qi. Thus, this is the method, starting from Zi year, ending at Hai year. Each year has six positions. Qi is below; Earth corresponds to Yin, still, position fixed and unchanging, year after year. Heaven's Qi moves and does not stop, occupying no fixed position, shifting with yearly Qi exchange. Si Tian (Heavenly Ruler) is the Third Qi, Di (Earth/Ruler Below) is the Final Qi. Left/Right Intermittent Qi: Earth's Left Intermittent is First Qi, Right is Fifth Qi; Heaven's Left Intermittent is Final Qi, Right is Second Qi. This is Guest Qi.
Guest moves above Principal; Principal is below Guest. Up/down summon each other, cold/heat approach, Yin/Yang cross, and changes arise.
These words regarding humans imply violating Heavenly Net, slightly differing. Establish Heaven/Earth fullness/emptiness first to clarify Su Yun (Yearly Movement) Tai/Shao (Greater/Lesser), distinguish prosperity/decline, deduce Six Steps' supervision, match regions, deduce encounters, and apply usage.
(New Addition) Heaven's Six Qi Yin/Yang move ceaselessly, cycling through six steps. Above Principal Positions, usually the year's Qi becomes Si Tian, becoming the Guest Qi of the Third Qi Ministerial Fire. The latter three Qi become the Guest Qi of the Zai Quan (In泉/Underground) Qi. Si Tian Qi has Southern and Northern Policies. Jia/Ji Earth Movement is Southern Policy Si Tian, Earth alone is honored; remaining Metal/Water/Fire/Wood are Northern Policy. Southern Policy turns with Heaven, determining Left/Right Intermittent Qi. For example, in Jia Zi year, Southern Policy Si Tian, Zi/Wu is Shao Yin, Sovereign Fire above, as Si Tian. Middle Tai Gong, Earth Movement. Advance three positions down to Mao, Jia combines with Ji, thus Ji Mao governs Earth. Adjacent Qi to Si Tian are Intermittent Qi. Zi is Si Tian, Shao Yin Sovereign Fire; Hai is Jue Yin Wind Wood, Right Intermittent; Chou is Tai Yin Damp Earth, Left Intermittent. Mao is Yang Ming Dry Metal, governs Earth; Yin is Shao Yang Ministerial Fire, Left Intermittent; Chen is Tai Yang Cold Water, Right Intermittent.
One year shifts one position, until six reside and return. Up/down approach, Yin/Yang cross, changes arise. Qi compatible is harmonious; incompatible causes disease. Principal defeating Guest makes Guest sick (Reversal); Guest defeating Principal makes Principal sick (Smooth). Principal/Guest victory has no repetition; Three Yin/Three Yang have their own prosperity/decline logic. Yin/Shen/Si/Hai are One Yin/One Yang; Zi/Wu/Mao/You are Two Yin/Two Yang; Chen/Xu/Chou/Wei are Three Yin/Three Yang. Deduce by meaning to know prosperity/decline variations.
Verse: Yearly Branch Qi is Si Tian (Year means year, Branch means branch, thus knowing Zi/Wu year Shao Yin Sovereign Fire is Si Tian, moving left one branch to Chou year, annually arriving becomes Si Tian Qi). Move left three branches to Zai Quan (Advance three branches to Mao/You, Yang Ming Zai Quan etc.). Heaven faces South speaking Left/Right (Si Tian position is South, facing North speaking its Left/Right Intermittent Qi). North Earth Left/Right faces South (Si Di position is North, facing South speaking its Left/Right Intermittent Qi). Si Tian becomes Third Qi Guest (Si Tian is Upper, both Southern/Northern policies have Si Tian, its Qi is Third Qi Guest). Earth is Final Qi necessarily (Si Di, also called Zai Quan, is Lower, thus Final Qi Guest). Earth Left Intermittent resides in Final Qi (Si Di Left Intermittent is Final Qi Guest, Si Di Right Intermittent is Fourth Qi Guest, Si Tian resides in Third Qi Guest). To know Earth Qi self-arrangement (Fourth Qi Si Tian, Right Intermittent resides in Second Qi, Si Di Final Qi same, deduce separately).
Si Tian Six Yuan True Qi: Each year, first three Qi are in Heaven, latter three in Earth. Of these six Qi, two are between Heaven/Earth, remaining four are Intermittent Qi. Si Tian Qi governs first half of year, three Qi; Zai Quan governs second half, three Qi. Si Tian properly governs Third Qi phase, ending after 30 days plus 43.75 ke. Remaining four Intermittent Qi are paths of Heaven/Earth Yin/Yang, each governing 60 days plus 87.5 ke. Total six steps equal 365.15 ke, forming one year.
Five Movements (Wu Yun): Each year generally governs one period, five form one cycle. Following one movement governs one year, Tai/Shao alternate. However, within one year, there are also Five Movements combining to govern one year. These Five Movements originate from the Principal, governed by Wood/Fire/Earth/Metal/Water successively. Usually Wood is First Movement, aligning with the day/time of transitioning to First Qi of the previous year. Next, Wood generates Fire as Second Movement, transitioning 13 days after Chun Fen. Next, Fire generates Earth as Third Movement, transitioning 25 days after Xiao Man. Next, Earth generates Metal as Fourth Movement, transitioning 37 days after Da Shu. Next, Metal generates Water as Fifth Movement, transitioning 49 days after Qiu Fen. Ending and restarting. Each movement is 73.5 ke, totaling one period. (This concerns Principal/Guest of Five Movements. Previous sections detail movement strategies adding up, easy to see.) Some say Five Movements in the year each have Principal/Guest, should use Principal/Guest. Use the two stems preceding the year stem as First Movement Guest, and add/subtract Five Movements up/down (The two stems preceding the year stem as Guest Movement are detailed in *Yu Ce*. Note: *Liu Yuan Zheng Ji Da Lun* says Heavenly Movement is First Movement). Calling it Dry is erroneous. However, Si Tian is above, Si Di is below, Su Yun is in the middle. Usually transporting Heaven/Earth Qi, rising/falling. Also, Six Steps Principal/Guest Qi: Guest Qi is above, Principal Qi is below, Yearly Heavenly Movement is in the middle, transporting up/down Principal/Guest Qi, rising/falling. All these are the Way of Three Powers, natural principle, origin of creation. One generates Two, Two generates Three, Three generates Ten Thousand Things. How can there be Principal/Guest Qi without something to transport them? It is likely erroneous. Movements have Tai/Shao, only identical to Yearly Movement Tai/Shao, up/down Tai/Shao follow. Erroneously starting Greater Jue in Yang years and Lesser Jue in Yin years is incorrect. (Previous Tai/Shao Jue diagram details methods, consistent with Canon.)
