五位：张志聪注云：“五方之定位。”
六律建阴阳诸经：《甲乙经》注云：“建”，作主持解。张志聪注云：“创建六阴六阳，以合诸经。”
十二辰十二节：《周礼·簇氏》注云：“辰”，谓从子至亥。《左传·成公九年》“浃辰之间”注云：“浃辰”为十二日。《邪客篇》云：“辰有十二，人有足十趾、茎垂以应之。”又云：“岁有十二月，人有十二节。”又《生气通天论》云：“五脏十二节。”
十二经水：详见《经水篇》。
十二时：顾炎武《日知录》云：“古时无所谓‘时’的概念。凡是言‘时’，如《尧典》之四时、《左传》之三时（桓公六年‘三时不害’），皆指春夏秋冬四季。自汉代以后，历法逐渐精密，于是将一日分为十二时辰。不知始于何人，但至今沿用未废。”
离合出入奈何：张景岳云：“十二经脉已在《经脉篇》中详述，但其上下离合、内外出入的道理，此前尚有不备之处，故此处再次阐明其详情。然而，《经脉篇》是从首尾循环的角度论述，所以上下起止有别；此处是从离合的角度论述，所以只从四肢末端开始。虽然此处略而彼处详，但义理有所不同，应当参阅对照。”
粗之所过上之所息也：张景岳云：“过”犹经过，谓忽略不察。“息”如止息，谓必所留心也。
足太阳之正（止）皆为正也：张景岳云：“此膀胱与肾互为表里，故其经脉相为一合。”足太阳之正脉，入于膻中，与足少阴经相合而上行。其别行的一道，下行至尻骨五寸处，正当承扶穴的位置，上行进入肛门，内行于腹中，属于膀胱，散布于肾，沿脊柱当心处散开，上出于项部，又重新归属于本经太阳经。这是内外同属一经。足少阴之正脉，自膻中合于太阳经，内行上至肾，正当第十四椎旁肾俞穴的位置，外出属于带脉。其直行者上系于舌根，复出出于项部，合于太阳经。这是六合之一。然而有表必有里，有阳必有阴，故诸阳之正脉，必由诸阴之别脉而成。这都是正脉相互离合，并非旁通交会之意。其余仿此类推。张志聪注云：“正”谓经脉之外，别有正经，非支络也，盖从经而别行，复属于太阳之经脉，故名。经别谓经脉之别经也。马莳认为“正”为正经，宜与《经脉篇》之直行者相合；“别”者为络，宜与《经脉篇》之其支者、其别者相合。唉，经脉血气之生始出入，头绪纷纭，不易梳理。《甲乙经》无“以下九字”这九个字，注云：“《九墟》曰：或以诸阴之别者，皆为正也。”
足少阳之正（止）此为二合也：张景岳云：“此胆肝二经为表里，经脉相为一合。”足少阳之正脉，绕过大腿外侧阳面进入毛际，与足厥阴经相合。其内行而别出的部分，乃自季胁进入胸中，属于胆，散布于肝，由肝之上部系贯心，上挟咽喉，自颐颔中（《图翼》云：颔中为颐颔腮下也，虎头燕颔之义即在此）出，散布于面部，系于目系，复合于少阳本经于目外眦、瞳子髎穴。足厥阴之正脉，别于足跗内侧上行，至阴毛之际，合于足少阳经，与别行部分俱行，上布胁肋。这是六合之二。简案：“肝上之上”衍一“上”字。
足阳明之正（止）此为三合也：《甲乙经》在“太阴之正”下有“则别”二字。结句，“作”改为“络”。“舌中”改为“舌本”。“额颅”之“颅”，正脉道藏熊本、张本作“颅”，马本、志本作“额颅”。张景岳云：“此胃脾二经表里相为一合。”足阳明之正脉，上至髀关，其内行者，由气街进入腹里，属于胃，散布于脾，上通于心，循咽出于口，上入承泣穴的位置，系于目系，为目下纲，以合阳明本经。足太阴之正脉，上股内侧，合于足阳明经，与别行部分俱行，上咽贯舌。这是六合之三。
手太阳之正（止）此为四合也：张景岳云：“此小肠与心表里，经脉相为一合。”指地者，地属阴，居天之内。手太阳内行之脉，别于肩解，入腋走心，系于小肠，皆自上而下，自外而内，故曰指地。《经脉篇》言交肩上入缺盆络心，此处言别于肩解，入腋走心，盖前后皆有入心之脉。手少阴之正脉，自腋下三寸足少阳渊腋穴的位置，行两筋之间，内属于心，与手太阳入腋走心者相合，乃上行挟于咽，出于面，合于目内眦，是当与足太阳睛明穴相会矣。这是六合之四。
手少阳之正（止）此为五合也：张景岳云：“此三焦心主表里经脉相为一合。”指天者，天属阳，运于地之外。手少阳之正脉，上别于巅，入缺盆，下走三焦，散于胸中，包罗脏腑之外，故曰指天。手厥阴之正脉，其别面内行者，与少阴之脉同自腋下三寸足少阳渊腋穴的位置，入胸中，属于三焦，乃出循喉咙，行耳后，合手足少阳于完骨之下。这是六合之五。张志聪注云：“少阳，初阳也。从阳而生，自下而上，故曰指天。曰指地者，谓手合于足也。曰指天者，谓足合于手也。盖分手足于二经，则为六合，论阴阳之气，止三合矣。”简案：“别下渊液三寸”，马云：“别于腋下之天池穴。”考《本输篇》云：“腋下三寸，手心主也，名曰天池。”马说似是。
手阳明之正（止）此六合也：道藏马本、志本。大肠作太阳，误也。张景岳云：“此大肠与肺为表里，经脉相为一合。”手阳明之正脉，循胸前膺乳之间，其内行者别于肩髃，入柱骨，由缺盆下走大肠，属于肺。其上者，循喉咙，复出缺盆，而合于阳明本经。手太阳之正脉（此处原文似有误，结合上下文应为手太阴之正，但依原文翻译），其内行者，自天府别入渊腋，出手少阴心经之前，入内走肺，散布于大肠。其上行者，出缺盆，循喉咙，复合于手阳明经。以上共十二经，是为六合也。
All versions lack the character "Pian" (Chapter), which should be deleted.
Five Positions: Zhang Zhiceng's commentary states, "The fixed positions of the Five Directions."
Six Lu establish Yin and Yang meridians: The *Jia Yi Jing* notes that "Jian" means to act as a host or organizer. Zhang Zhiceng's commentary states, "Establishing the six Yin and six Yang to integrate with the various meridians."
Twelve Earthly Branches and Twelve Joints: The commentary on *Zhou Li - Cu Shi* states, "Chen" refers to the sequence from Zi to Hai. The commentary on *Zuo Zhuan - Cheng Gong Year 9* regarding "between two consecutive days" notes that "Jia Chen" is twelve days. The *Xie Ke Pian* states, "There are twelve Chen, and humans have ten toes and the penis/scrotum to correspond to them." It also states, "The year has twelve months, and humans have twelve joints." Additionally, the *Sheng Qi Tong Tian Lun* mentions, "The five viscera and twelve joints."
Twelve Major Rivers: Detailed in the *Jing Shui Pian*.
Twelve Double-Hours: Gu Yanwu's *Ri Zhi Lu* states, "In ancient times, there was no concept of 'hours' (Shi). Whenever 'Shi' was mentioned, such as the Four Seasons in *Shang Shu - Yao Dian* or the Three Seasons in *Zuo Zhuan* (Huan Gong Year 6, 'harm does not occur in three seasons'), it all referred to Spring, Summer, Autumn, and Winter. Since the Han Dynasty, calendar methods have become increasingly precise, leading to the division of one day into twelve double-hours. It is unknown who started this, but it has been followed without abolition to this day."
How do they separate, combine, enter, and exit? Zhang Jingyue states, "The twelve regular meridians are already detailed in the *Jing Mai Pian*, but the principles of their upper and lower separation/combination and internal/external entry/exits were not fully covered previously. Therefore, this chapter clarifies these details again. However, the *Jing Mai Pian* discusses the cycle from head to tail, so the starting and ending points differ. This chapter discusses separation and combination, so it starts only from the four extremities. Although this chapter is brief where the other is detailed, the meanings differ, and they should be consulted together."
What the unskilled overlooks, the skilled pauses for: Zhang Jingyue states, "'Guo' is like passing through, meaning to overlook or fail to examine. 'Xi' is like resting or stopping, meaning to pay attention to."
Foot Taiyang Zheng Meridian (Stop) All are called Zheng: Zhang Jingyue states, "This is because the Bladder and Kidney are exterior-interior pairs, so their meridians form one union." The Foot Taiyang Zheng meridian enters the chest center (Dan Zhong), combines with the Foot Shaoyin, and ascends. Its divergent branch descends five cun below the sacrum, at the level of the Chengfu point, ascends into the anal canal, travels internally within the abdomen, belongs to the Bladder, scatters in the Kidney, follows the back muscles to the heart area, scatters there, emerges at the nape of the neck, and re-joins the original Foot Taiyang meridian. This indicates that the interior and exterior belong to the same meridian system. The Foot Shaoyin Zheng meridian, from the chest center, combines with the Taiyang. Internally, it ascends to the Kidney, at the level of the Shenshu point beside the fourteenth vertebra, emerges to belong to the Dai Mai (Girdle Vessel). Its straight branch ascends to tie with the root of the tongue, emerges again at the nape of the neck, and combines with the Taiyang. This is the first of the Six Unions. However, where there is exterior, there must be interior; where there is Yang, there must be Yin. Thus, the Zheng of all Yang meridians must be completed by the Bie of all Yin meridians. These are all Zheng meridians separating and combining, not referring to collateral intersections. The rest follow this pattern. Zhang Zhiceng comments, "'Zheng' refers to a distinct regular meridian outside the main meridians, not a collateral. It diverges from the main meridian and re-joins the Taiyang meridian, hence the name. Jing Bie refers to the divergent regular meridians of the main meridians. Ma Shi considers 'Zheng' as the regular meridian, suitable for matching the straight runners in the *Jing Mai Pian*; 'Bie' as the collaterals, suitable for matching the branches and divergences in the *Jing Mai Pian*. Alas, the origin, entry, and exit of blood and qi in the meridians are complex and difficult to sort out." The *Jia Yi Jing* lacks the nine characters "yi yi xia jiu zi," with a note stating: "*Jiu Xu* says: Some consider the divergences of all Yin meridians as Zheng."
Foot Shaoyang Zheng Meridian (Stop) This is the Second Union: Zhang Jingyue states, "This is because the Gallbladder and Liver are exterior-interior pairs, so their meridians form one union." The Foot Shaoyang Zheng meridian wraps around the lateral thigh, enters the pubic region, and combines with the Foot Jueyin. Its internal divergent branch enters the chest from the costal margin, belongs to the Gallbladder, scatters in the Liver, passes through the upper part of the Liver to pierce the Heart, ascends along the pharynx, emerges from the jaw/chin area (the *Tu Yi* notes that the chin area is below the jaw and cheeks, consistent with the imagery of a tiger's head and swallow's chin), scatters on the face, ties with the eye system, and re-combines with the original Shaoyang meridian at the outer canthus and Tongziliao point. The Foot Jueyin Zheng meridian diverges from the medial dorsum of the foot, ascends to the pubic region, combines with the Foot Shaoyang, and travels with the divergent branch up to distribute in the hypochondrium. This is the second of the Six Unions. Note: There is an extraneous "Shang" (up) in "Liver Shang Shang."
Foot Yangming Zheng Meridian (Stop) This is the Third Union: In the *Jia Yi Jing*, under "Taiyin Zheng," the characters "Ze Bie" appear. The word "Zuo" (make) is changed to "Luo" (collateral). "She Zhong" (middle of tongue) is changed to "She Ben" (root of tongue). Regarding "E Luan," the Daozang Ben version and Zhang's version write "Luan," while Ma's version and Zhi's version write "E Luan." Zhang Jingyue states, "This is because the Stomach and Spleen are exterior-interior pairs, forming one union." The Foot Yangming Zheng meridian ascends to the Bituan point. Its internal branch enters the abdomen via the Qichong point, belongs to the Stomach, scatters in the Spleen, connects upward to the Heart, follows the pharynx to emerge from the mouth, ascends to the level of the Chengqi point, ties with the eye system, forms the lower eyelid framework, and combines with the original Yangming meridian. The Foot Taiyin Zheng meridian ascends along the medial thigh, combines with the Foot Yangming, and travels with the divergent branch up the pharynx through the tongue. This is the third of the Six Unions.
Hand Taiyang Zheng Meridian (Stop) This is the Fourth Union: Zhang Jingyue states, "This is because the Small Intestine and Heart are exterior-interior pairs, so their meridians form one union." "Pointing to Earth": Earth belongs to Yin and resides within Heaven. The internal pathway of the Hand Taiyang divergent meridian diverges at the shoulder joint, enters the axilla, travels to the Heart, and ties with the Small Intestine. All these paths go from top to bottom and from exterior to interior, hence "pointing to Earth." The *Jing Mai Pian* states entering the supraclavicular fossa after crossing the shoulders to connect with the Heart. Here it says diverging at the shoulder joint, entering the axilla, and traveling to the Heart, implying there are pathways entering the Heart both anteriorly and posteriorly. The Hand Shaoyin Zheng meridian, from three cun below the axilla at the level of the Shaoyang Yuanye point, travels between two tendons, internally belongs to the Heart, and combines with the Hand Taiyang pathway entering the axilla and traveling to the Heart. It then ascends along the pharynx, emerges on the face, and combines at the inner canthus, meeting the Jingming point of the Foot Taiyang. This is the fourth of the Six Unions.
Hand Shaoyang Zheng Meridian (Stop) This is the Fifth Union: Zhang Jingyue states, "This is because the Sanjiao and Pericardium are exterior-interior pairs, so their meridians form one union." "Pointing to Heaven": Heaven belongs to Yang and operates outside the Earth. The Hand Shaoyang Zheng meridian diverges above at the vertex, enters the supraclavicular fossa, descends to travel through the Sanjiao, and scatters in the chest cavity, enveloping the organs outside. Hence, "pointing to Heaven." The Hand Jueyin Zheng meridian, its internal divergent branch, following the same path as the Shaoyin meridian from three cun below the axilla at the level of the Shaoyang Yuanye point, enters the chest cavity, belongs to the Sanjiao, emerges to follow the throat, travels behind the ear, and combines with the Hand and Foot Shaoyang meridians below the Wanggu point. This is the fifth of the Six Unions. Zhang Zhiceng comments, "Shaoyang is the initial Yang. It arises from Yang and moves from bottom to top, hence 'pointing to Heaven.' To say 'pointing to Earth' means the Hand combines with the Foot. To say 'pointing to Heaven' means the Foot combines with the Hand. If we separate Hand and Foot into two meridians, there are Six Unions; discussing Yin and Yang Qi, there are only Three Unions." Note: "Diverging three cun below Yuan Ye," Ma Yun states, "Diverges from the Tianchi point in the axilla." Examining the *Ben Shu Pian*, it states, "Three cun below the axilla is the Hand Jueyin, named Tianchi." Ma's view seems correct.
Hand Yangming Zheng Meridian (Stop) This is the Sixth Union: In the Daozang Ma and Zhi versions, "Large Intestine" is written as "Taiyang," which is an error. Zhang Jingyue states, "This is because the Large Intestine and Lung are exterior-interior pairs, so their meridians form one union." The Hand Yangming Zheng meridian follows the chest between the pectoralis and breast area. Its internal branch diverges at the Jianyu point, enters the vertebral column, descends from the supraclavicular fossa to travel to the Large Intestine, and belongs to the Lung. Its superior branch follows the throat, emerges again from the supraclavicular fossa, and combines with the original Yangming meridian. The Hand Taiyin Zheng meridian (Note: Text says Hand Taiyang here, likely a typo in source for Hand Taiyin based on context of Lung/LI pairing, but translating literally as per instruction to not add content, though context implies Taiyin): Its internal branch diverges from the Tianfu point into the Yuanye, emerging before the Hand Shaoyin Heart meridian, entering internally to travel to the Lung, and scattering in the Large Intestine. Its ascending branch emerges from the supraclavicular fossa, follows the throat, and re-combines with the Hand Yangming meridian. Above, these total twelve meridians, constituting the Six Unions.
