子午流注者。谓刚柔相配。阴阳相合。气血循环。时穴开阖也。子时一刻乃一阳之生。
午时一刻乃一阴之生。子午为阴阳之消息也。流者往也。注者住也。天干有十。经有十二。甲胆
乙肝丙小肠。丁心戊胃。己脾。庚大肠。辛肺壬膀胱癸肾。余两经三焦包络也。三焦乃阳气
之父包络乃阴血之母。三焦寄于丙。包络寄于丁。以类从也(旧本三焦寄于壬。包络寄于癸
。误)每经之中。有井荥 经合。以配金水木火土是。故阴井木而阳井金。阴荥火而阳荥水
。阴 土而阳 木。阴经金而阳经火。阴合水而阳合土。经中有返本还元者乃十二经出入之
门也。阳经有原。遇 穴并过之。阴经无原。以 穴代为之。是以甲出丘墟。乙出太冲。又
按千金云六阴经亦有原穴。乙中都。丁通里内关(旧本包络内关寄于癸。误)巳公孙。辛列缺
。癸水泉是也。故阳日气先行而血后随也。阴日血先行而气后随也。得时为之开。失时为之
阖。阳干注府。甲丙戊庚壬而重见者。气纳三焦。阴干注藏乙丁己辛癸而重见者。血纳包络
。如甲日。甲戌时开在胆井。至戊寅时正当胃 。而又并过胆原。至甲申时重见甲。是以气
纳三焦荥穴。阳荥属水。甲属木。是以水生木。谓甲合还元化木。又如乙日乙酉时开在肝井
至己丑时当脾之 并过肝原。至乙未时重见乙。是以血纳包络荥穴。阴荥属火。乙属木。是
以木生火也。余仿此。俱以子午相生。阴阳相济。阳日无阴时。阴日无阳时。故甲与己合。
乙与庚合。丙与辛合。丁与壬合戊与癸合也。何以甲与己合。盖中央戊己属土。畏东方甲乙
之木所克。戊乃阳为兄。己属阴为妹。戊兄遂将己妹嫁与木家与甲为妻。庶得阴阳和合而不
相伤。所以甲与己合。其余皆然。此所谓子午之法也。

（徐氏的书籍现在已经校正）
子午流注，指的是天干地支中刚柔相配、阴阳相合，气血在经络中循环流转，以及特定时间穴位开阖的规律。
子时（夜间11点至凌晨1点）的一刻是阳气初生之时。
午时（中午11点至下午1点）的一刻是阴气初生之时。
子与午代表了阴阳消长的变化。
“流”意为运行向前，“注”意为停留汇聚。
天干有十个，经脉有十二条。
甲对应胆，乙对应肝，丙对应小肠，丁对应心，戊对应胃，己对应脾，庚对应大肠，辛对应肺，壬对应膀胱，癸对应肾。
剩下的两条经脉是三焦和心包络。
三焦是阳气的父亲，心包络是阴血的母亲。
三焦寄附于丙火，心包络寄附于丁火，这是遵循同类相聚的原则。（旧版书籍中记载三焦寄附于壬水，心包络寄附于癸水，这是错误的。）
每条经脉中都有井、荥、输、经、合五穴，用来配合金、水、木、火、土五行。
所以阴经的井穴属木，阳经的井穴属金；阴经的荥穴属火，阳经的荥穴属水；阴经的输穴属土，阳经的输穴属木；阴经的经穴属金，阳经的经穴属火；阴经的合穴属水，阳经的合穴属土。
经穴中有“返本还元”的现象，那是十二经脉出入的关键门户。
阳经有原穴，遇到输穴时一并经过（即输穴兼作原穴）。
阴经没有单独的原穴，以输穴代替原穴。
因此，甲日（胆经）的气血出于丘墟穴，乙日（肝经）的气血出于太冲穴。
另外根据《千金方》记载，六条阴经也有原穴：乙日（肝经）的原穴是中都，丁日（心经）的原穴是通里和内关（旧版书籍中记载心包络的内关寄附于癸水，这是错误的），巳日（脾经）的原穴是公孙，辛日（肺经）的原穴是列缺，癸日（肾经）的原穴是水泉。
所以阳日运行时，气先行而血随后跟随；阴日运行时，血先行而气随后跟随。
得到合适的时间穴位就开启，失去合适的时间穴位就闭合。
阳干（甲、丙、戊、庚、壬）注入腑，如果重见该阳干，则气纳入三焦。
阴干（乙、丁、己、辛、癸）注入脏，如果重见该阴干，则血纳入心包络。
例如甲日，甲戌时开启的是胆经的井穴，到了戊寅时正当胃经的输穴，并且同时经过胆经的原穴，到了甲申时再次见到甲干，这时气就纳入三焦的荥穴。
阳经的荥穴属水，甲属木，水生木，称为甲合还元化木。
又如乙日，乙酉时开启的是肝经的井穴，到了己丑时正当脾经的输穴并经过肝经的原穴，到了乙未时再次见到乙干，这时血就纳入心包络的荥穴。
阴经的荥穴属火，乙属木，木生火。
其余情况都仿照此理。
都是依据子午相生、阴阳相济的原理。
阳日没有阴时，阴日没有阳时，所以甲与己相合，乙与庚相合，丙与辛相合，丁与壬相合，戊与癸相合。
为什么甲与己相合呢？
因为中央的戊己属土，畏惧东方甲乙之木的克制。
戊为阳，好比兄长；己为阴，好比妹妹。
戊兄便将己妹嫁给木家，让甲作为妻子，从而使得阴阳和谐而不互相伤害。
所以甲与己相合。其他干支的配合也都以此类推。
这就是所谓的子午之法。

上述阳图的方法，按照胆、胃、小肠、大肠、膀胱的顺序排列，如胆经的井穴窍阴，至小肠经的荥穴前谷，胃经的输穴陷谷，大肠经的经穴阳溪。
第三次循环经过胃经的井穴厉兑，大肠经的荥穴二间，膀胱经的输穴束骨，胆经的经穴阳辅，小肠经的合穴小海。
第四次循环经过大肠经的井穴商阳，膀胱经的荥穴通谷，胆经的输穴足临泣，小肠经的经穴阳谷，胃经的合穴足三里。
第五次循环经过膀胱经的井穴至阴，胆经的荥穴侠溪，小肠经的输穴后溪，胃经的经穴解溪，大肠经的合穴曲池。
以上各阳经的原穴，都在输穴处一并经过。
当再次遇到阳干时，气纳入三焦。
○ 阴图以肝、心、脾、肺、肾的顺序依次推算输穴数量，如同阳图那样流通转换。
各阴经的原穴即是输穴。
也在输穴处一并经过。
当再次遇到阴干时，血纳入心包络。

Ziwu Liuzhu (Sub-meridian Flowing and Pouring Method) refers to the matching of rigidity and softness, the harmony of Yin and Yang, the cyclic circulation of Qi and Blood, and the opening and closing of acupoints at specific times.
At the beginning of Zi hour (11:00 PM - 1:00 AM), Yang Qi begins to generate.
At the beginning of Wu hour (11:00 AM - 1:00 PM), Yin Qi begins to generate.
Zi and Wu represent the waxing and waning of Yin and Yang.
"Liu" (Flow) means moving forward; "Zhu" (Pour/Stop) means staying or gathering.
There are ten Heavenly Stems and twelve Meridians.
Jia corresponds to Gallbladder, Yi to Liver, Bing to Small Intestine, Ding to Heart, Wu to Stomach, Ji to Spleen, Geng to Large Intestine, Xin to Lung, Ren to Bladder, Gui to Kidney.
The remaining two meridians are Sanjiao (Triple Burner) and Pericardium.
Sanjiao is the father of Yang Qi, and Pericardium is the mother of Yin Blood.
Sanjiao is affiliated with Bing Fire, and Pericardium is affiliated with Ding Fire, following the principle of similarity attracting similarity. (In old editions, it was recorded that Sanjiao is affiliated with Ren Water and Pericardium with Gui Water, which is incorrect.)
Within each meridian, there are Jing-River, Ying-Spring, Shu-Stream, Jing-River, and He-Sea points, corresponding to Metal, Water, Wood, Fire, and Earth.
Thus, the Jing-River point of Yin meridians belongs to Wood, while that of Yang meridians belongs to Metal; the Ying-Spring point of Yin meridians belongs to Fire, while that of Yang meridians belongs to Water; the Shu-Stream point of Yin meridians belongs to Earth, while that of Yang meridians belongs to Wood; the Jing-River point of Yin meridians belongs to Metal, while that of Yang meridians belongs to Fire; the He-Sea point of Yin meridians belongs to Water, while that of Yang meridians belongs to Earth.
Among the Jing-River points, there is a phenomenon of "returning to the origin," which serves as the gate of entry and exit for the twelve meridians.
Yang meridians have Yuan-Source points; when reaching the Shu-Stream points, they pass through them simultaneously (the Shu-Stream point acts as the Yuan-Source point).
Yin meridians do not have separate Yuan-Source points; their Shu-Stream points serve as Yuan-Source points.
Therefore, on Jia days (Gallbladder meridian), Qi emerges from Qiu Xu (GB40); on Yi days (Liver meridian), Qi emerges from Tai Chong (LR3).
Furthermore, according to *Qian Jin Fang*, the six Yin meridians also have Yuan-Source points: on Yi days (Liver meridian), the Yuan-Source point is Zhong Du (LR6); on Ding days (Heart meridian), the Yuan-Source points are Tong Li (HT5) and Nei Guan (PC6) [Note: Old editions incorrectly stated Pericardium's Nei Guan is affiliated with Gui Water]; on Ji days (Spleen meridian), the Yuan-Source point is Gong Sun (SP4); on Xin days (Lung meridian), the Yuan-Source point is Lie Que (LU7); on Gui days (Kidney meridian), the Yuan-Source point is Shui Quan (KI5).
Thus, on Yang days, Qi moves first and Blood follows; on Yin days, Blood moves first and Qi follows.
When the appropriate time arrives, the acupoint opens; when the time passes, it closes.
Yang stems (Jia, Bing, Wu, Geng, Ren) nourish the Fu organs. If a Yang stem reappears, Qi is absorbed into the Sanjiao.
Yin stems (Yi, Ding, Ji, Xin, Gui) nourish the Zang organs. If a Yin stem reappears, Blood is absorbed into the Pericardium.
For example, on a Jia day, at Jia Xu hour, the Jing-River point of the Gallbladder is opened. By Wu Yin hour, it reaches the Shu-Stream point of the Stomach, passing through the Yuan-Source point of the Gallbladder. At Jia Shen hour, the Jia stem reappears, so Qi is absorbed into the Ying-Spring point of the Sanjiao.
The Ying-Spring points of Yang meridians belong to Water, and Jia belongs to Wood; Water generates Wood, referred to as "Jia combining to return to origin and transform into Wood."
Similarly, on a Yi day, at Yi You hour, the Jing-River point of the Liver is opened. By Ji Chou hour, it reaches the Shu-Stream point of the Splea, passing through the Yuan-Source point of the Liver. At Yi Wei hour, the Yi stem reappears, so Blood is absorbed into the Ying-Spring point of the Pericardium.
The Ying-Spring points of Yin meridians belong to Fire, and Yi belongs to Wood; Wood generates Fire.
The rest follow this pattern.
All are based on the generation of Zi and Wu, and the mutual assistance of Yin and Yang.
Yang days have no Yin hours, and Yin days have no Yang hours. Therefore, Jia combines with Ji, Yi with Geng, Bing with Xin, Ding with Ren, and Wu with Gui.
Why does Jia combine with Ji?
Because the central Wu and Ji belong to Earth, which fears being controlled by the Wood of Eastern Jia and Yi.
Wu is Yang, like an elder brother; Ji is Yin, like a younger sister.
The elder brother Wu marries his sister Ji to the Wood family, making Jia his wife, thereby achieving harmony between Yin and Yang without mutual harm.
Thus, Jia combines with Ji. The same logic applies to the others.
This is what is called the method of Zi and Wu.
[Diagram of Yang Stems Ziwu Liuzhu]
[Diagram of Yin Stems Ziwu Liuzhu]
The method of the above Yang diagram arranges the Gallbladder, Stomach, Small Intestine, Large Intestine, and Bladder in sequence. For instance, the Jing-River point Qiao Yin (GB2) of the Gallbladder, up to the Ying-Spring point Qian Gu (SI3) of the Small Intestine, the Shu-Stream point Xian Gu (ST41) of the Stomach, and the Jing-River point Yang Xi (LI5) of the Large Intestine.
In the third cycle, it passes through the Jing-River point Li Dui (ST45) of the Stomach, the Ying-Spring point Er Jian (LI2) of the Large Intestine, the Shu-Stream point Shu Gu (BL65) of the Bladder, the Jing-River point Yang Fu (GB38) of the Gallbladder, and the He-Sea point Xiao Hai (SI8) of the Small Intestine.
In the fourth cycle, it passes through the Jing-River point Shang Yang (LI1) of the Large Intestine, the Ying-Spring point Tong Gu (BL67) of the Bladder, the Shu-Stream point Zu Lin Qi (GB41) of the Gallbladder, the Jing-River point Yang Gu (SI5) of the Small Intestine, and the He-Sea point Zu San Li (ST36) of the Stomach.
In the fifth cycle, it passes through the Jing-River point Zhi Yin (BL67) of the Bladder, the Ying-Spring point Xia Xi (GB43) of the Gallbladder, the Shu-Stream point Hou Xi (SI3) of the Small Intestine, the Jing-River point Jie Xi (ST41) of the Stomach, and the He-Sea point Qu Chi (LI11) of the Large Intestine.
The Yuan-Source points of all the above Yang meridians are passed through simultaneously at the Shu-Stream points.
When a Yang stem reappears, Qi is absorbed into the Sanjiao.
○ The Yin diagram calculates the number of Shu-Stream points for the Liver, Heart, Spleen, Lung, and Kidney in sequence, circulating similarly to the Yang diagram.
The Yuan-Source points of each Yin meridian are their respective Shu-Stream points.
They are also passed through simultaneously at the Shu-Stream points.
When a Yin stem reappears, Blood is absorbed into the Pericardium.
