黄帝问于岐伯曰∶凡刺之道，必通十二经脉之所终始，（手之三阴，始之于胸，终于手指；
手之三阳，始于手指，终之于头。足之三阳，始起于头，终之于足；足之三阴，始起于足，终之

【平按】：本篇从篇首到篇末，见于《灵枢》卷一第二篇《本输》，从肺经井穴少商以下的内容，散见于《甲乙经》卷三第二十四至三十五等篇，虽然意义大多相同，但编排顺序前后、文字繁简有所不同。从“肺合大肠”到“所合者也”，见于《甲乙经》卷一第三篇。
黄帝向岐伯问道：凡是针刺的道理，必须通晓十二经脉的起止点，（手三阴经，起始于胸部，终止于手指；手三阳经，起始于手指，终止于头部。足三阳经，起始于头部，终止于足部；足三阴经，起始于足部，终止于腹部。【平按】：《灵枢》中“经脉”写作“经络”。）络脉的别出起点，（十五络脉，都是从脏腑的正经别行走入他处。【平按】：《灵枢》中“别起”写作“别处”。）五输穴（井、荥、输、经、合）的气血留止之处，（各穴从井穴流出，留止于合穴。【平按】：《灵枢》中没有“止”字。）五脏六腑的表里配合关系，（五脏六经为里，六腑六经为表，表里相合。【平按】：《灵枢》中没有“五脏”二字。）四时气候的出入变化，（秋冬季节，阳气从体表进入骨髓，阴气从体内出于体表；春夏季节，阴气从体表进入骨髓，阳气从体内出于体表。）脏腑之气的流行运行，（脏腑之气源于营气和卫气，在全身流行。【平按】：《灵枢》中“脏腑”写作“五脏”，“流行”写作“溜处”。）经脉宽窄疏密的度量，（营卫运行的宽窄疏密程度。）深浅的状态，（络脉位置浅，经脉位置深。）高低到达的部位，希望听听您的解说。（经脉高至头部，下至足部。这九个方面的义理，我都希望能听到解释。）
岐伯回答说：请让我按次序说明。（次序，指井、荥、输、经、合等阴阳五行生克的次第。）
肺经的井穴是少商，少商穴位于手大拇指内侧端，属井穴；（肺脉从内脏发出，行至食指末端，现在说到大拇指末端，是回归入脏，这是依据经脉顺行从手逆数的方法。井，古人以泉水源头出水之处称为井，掘地得水后，仍以本源为名，所以叫井。人的气血出于四肢，所以脉气出处称为井。手足三阴经都以木为井，相生直到水的合穴；手足三阳经都以金为井，相生直到土的合穴。这就是所谓阴脉出于阳，至阴而合；阳脉出于阴，至土而合。【平按】：《灵枢》和《甲乙经》在“指”下有“端”字，在“井”下有“木”字。）气血流注于鱼际，鱼际穴位于手掌大鱼际部位，属荥穴；（手腕前大骨之后，形状像鱼形，所以叫手鱼。脉气从少商流出，溢入鱼际，所以称为荥。读音同“迥”。）气血灌注于太渊，太渊穴位于鱼际后方凹陷处，属输穴；（输，意为送致聚集。《八十一难经》说：五脏的输穴，是三焦运行气机停留的地方。所以肺气与三焦之气送致聚集于此，所以名为输。【平按】：太渊，《灵枢》和《甲乙经》作“太泉”，说法见前文。“下”字，《灵枢》作“一寸”二字，“输”字作“俞”，《甲乙经》也作“俞”，下面不再重复列举。）气血运行于经渠，经渠穴位于寸口部位，搏动不停止，属经穴；（寸口部位，十二经脉流经沟渠，所以叫经渠。居，即停。太阴肺经的脉搏动于寸口不息，所以叫不居。经，即通，肺气至此常通，所以叫经。【平按】：《千金方》在“行于经渠”上有“过于列缺为源”六个字。）气血进入尺泽，尺泽穴位于肘窝中间的动脉处，属合穴，是手太阴肺经的合穴。（如水从井流出，最终汇入大海为合，脉气从手指井穴流出，至此与本脏之气相合，所以名为合，其余十个输穴的解释都参照此例。诸输穴的名称含义，已在《明堂》中详细解释。）
心包经（手心主）的井穴是中冲，中冲穴位于手中指指尖，属井穴；气血流注于劳宫，劳宫穴位于掌心中，中指本节内侧间，属荥穴；（《明堂》又称五星穴，是掌中动脉跳动处。【平按】：《甲乙经》中“心”作“心主”。《灵枢》在“井”下有“木”字。）气血灌注于大陵，大陵穴位于腕后两骨之间的下方，属输穴；【平按】：《千金方》在“为输”下有“过于内关为源”六个字。“两骨之间方下者也”，《甲乙经》作“两筋间陷者中”。气血运行于间使，间使穴在两筋之间，距腕横纹三寸处，有病邪则气至此处，无病邪则气止于此，属经穴；（方下，即凹陷处。三寸之中，即三寸之际。有虚实之邪，则气使至此；无邪则不至，故止。《明堂》在此手心主经下，还有手少阴心经的五输穴，此经所说心不受邪，所以手少阴经没有输穴。【平按】：《灵枢》在“道”上有“之”字。）气血进入曲泽，曲泽穴位于肘内侧廉下方的凹陷处，屈肘可得，属合穴，是手心主经的合穴。
肝经的井穴是大敦，大敦穴位于足大趾尖端及丛毛之中，属井穴；（足大趾端及丛毛都是大敦穴，是厥阴肝经的井穴。【平按】：《甲乙经》中“屈而得之”作“屈肘得之”。《灵枢》中“手心主”作“手少阴”。《灵枢》在“井”下有“木”字。）气血流注于行间，行间穴位于大趾和二趾之间，属荥穴；（《明堂》记载足厥阴肝经脉搏动应手。【平按】：《灵枢》在“大指”上有“足”字。）气血灌注于太冲，太冲穴位于行间穴上二寸的凹陷处，属输穴；（《明堂》记载在本节后二寸或一寸半的凹陷处。【平按】：《灵枢》在“行间上”没有“者”和“二”字。）气血运行于中封，中封穴位于内踝前一寸半的凹陷处，气行不畅则郁结，气行调和则通畅，摇足可取到，属经穴；（气行称为使。宛，即不舒展，堵塞。《明堂》记载在内踝前一寸，仰足取之，在凹陷处。伸足才能取到。【平按】：《千金方》有“过于中封为源，行于中...为经”的说法，与此不同。）气血进入曲泉，曲泉穴位于辅骨之下、大筋之上，屈膝可得，属合穴，是足厥阴肝经的合穴。（《明堂》记载在膝内辅骨下，大筋上，小筋下，凹陷处。）
脾经的井穴是隐白，隐白穴位于足大趾内侧端，属井穴；气血流注于大都，大都穴位于本节之后下方的凹陷处，属荥穴；气血灌注于太白，太白穴位于核骨之下，属输穴；（核骨在大趾本节之后，然骨之前的高骨就是核骨。核，音“茎革反”。【平按】：《灵枢》在“井”下有“木”字，大都写作“太都”。核字袁刻误作“腕”，注释同。注：核，音“茎革反”，袁刻没有这四个字。）气血运行于商丘，商丘穴位于内踝下方的凹陷处，属经穴；（《明堂》记载在足内踝下微前方。【平按】：《千金方》在“行于商丘”上有“过于公孙为源”六个字。）气血进入阴陵泉，阴陵泉穴位于辅骨下方的凹陷处，屈伸可得，属合穴，是足太阴脾经的合穴。（膝下内侧辅骨下。【平按】：《灵枢》没有“屈”字，太阴下没有“经”字。）

小肠经上合于手太阳小肠经，井穴是少泽，少泽穴位于小指端，属井穴；（《明堂》又称少吉，距离爪甲下一分凹陷中。【平按】：《灵枢》中“盛”作“实”，小肠上有“手太阳”三字，《灵枢》在“井”下有“金”字。）气血流注于前谷，前谷穴位于手小指本节之前凹陷处，属荥穴；（《明堂》记载在手小指外侧中。【平按】：《灵枢》中“小指”作“外廉”。）气血灌注于后溪，后溪穴位于本节之后，属输穴；（《明堂》记载在手小指外侧本节后凹陷中。【平按】：《灵枢》在“本节”上有“在手外侧”四字。）气血经过腕骨，腕骨穴位于手外侧腕骨之前，属原穴；（《明堂》记载在手外侧腕前起骨下凹陷中。即此起骨为腕骨，此经名完骨。完，音“胡端反”。【平按】：完骨，《灵枢》和《甲乙经》作“腕骨”。）气血运行于阳谷，阳谷穴位于兑骨之下凹陷处，属经穴；（《明堂》记载在手外侧腕中兑骨之下。【平按】：
[Ping An]: This chapter, from the beginning to the end, is found in *Lingshu* (Spiritual Pivot), Volume 1, Chapter 2 "Ben Shu" (Roots and Acupoints). From the Lung meridian's Jing-well point Shaoshang downwards, the content is scattered across chapters 24 to 35 of Volume 3 of *Jiayi Jing* (Systematic Classic of Acupuncture and Moxibustion). Although the meanings are largely identical, the arrangement order and textual complexity differ. From "The Lung combines with the Large Intestine" to "that which combines," it is found in Chapter 3 of Volume 1 of *Jiayi Jing*.
Yellow Emperor asked Qibo: In all matters of acupuncture, one must understand the starting and ending points of the twelve primary meridians. (The three Yin meridians of the hand start from the chest and end at the fingers; the three Yang meridians of the hand start from the fingers and end at the head. The three Yang meridians of the foot start from the head and end at the feet; the three Yin meridians of the foot start from the feet and end at the abdomen. [Ping An]: *Lingshu* writes "meridians" as "jingluo".) The starting points where collateral vessels branch off. (The fifteen Luo-connecting vessels all branch off from the primary meridians of the Zang and Fu organs and enter elsewhere. [Ping An]: *Lingshu* writes "bieqi" as "biechu".) The sites where Qi stagnates and accumulates at the Five Shu points (Jing-well, Ying-spring, Shu-stream, Jing-river, He-sea). (Qi flows out from the Jing-well points and stagnates at the He-sea points. [Ping An]: *Lingshu* lacks the character "zhi".) The combinations between the five Zang organs and six Fu organs. (The five Zang and their six meridians constitute the interior; the six Fu and their six meridians constitute the exterior, forming interior-exterior pairs. [Ping An]: *Lingshu* lacks the characters "wuzang".) The entry and exit of seasonal influences. (In autumn and winter, Yang Qi enters from the skin surface into the bone marrow, while Yin Qi exits from the interior to the skin surface; in spring and summer, Yin Qi enters from the skin surface into the bone marrow, while Yang Qi exits from the interior to the skin surface.) The circulation of Qi within the Zang and Fu organs. (Zang and Fu Qi originates from Ying-nourishing and Wei-protective Qi and circulates throughout the body. [Ping An]: *Lingshu* writes "zangfu" as "wuzang" and "liuxing" as "liuchu".) The measurements of width and density of the meridians. (The width and density of Ying and Wei Qi circulation.) The states of depth and superficiality. (Collateral vessels are superficial; primary meridians are deep.) The extent of their high and low reaches. I wish to hear your explanation. (Meridians extend high to the head and low to the feet. Regarding these nine principles, I request to hear them all explained.)
Qibo replied: Let me explain them in sequence. (Sequence refers to the order of the Five Shu points—Jing-well, Ying-spring, Shu-stream, Jing-river, He-sea—and their corresponding Yin-Yang and Five Elements progression.)
The Lung meridian's Jing-well point is Shaoshang. Shaoshang is located at the medial tip of the thumb and belongs to the Jing-well category. (The Lung meridian originates from the internal organ and travels to the tip of the index finger. Here, mentioning the thumb tip indicates returning to the organ, following the method of counting backwards from the hand along the forward-flowing meridian. 'Jing' (Well): Ancient people called the source where spring water emerges a 'well'. After digging to find water, it retains the name of its source, hence 'Well'. Human Blood and Qi emerge from the four limbs, so the point where the pulse emerges is called a Well. All three Yin meridians of the hand and foot use Wood as their Jing-well point, generating through to the Water He-sea point; all three Yang meridians use Metal as their Jing-well point, generating through to the Earth He-sea point. This is what is meant by Yin meridians emerging from Yang and combining at Yin, and Yang meridians emerging from Yin and combining at Earth. [Ping An]: *Lingshu* and *Jiayi Jing* add the character "duan" (tip) after "zhi" (finger), and add "mu" (Wood) after "jing" (well).) Qi flows into Yuji. Yuji is located on the thenar eminence (the fleshy part of the palm resembling a fish) and belongs to the Ying-spring category. (Behind the large joint of the wrist, shaped like a fish, hence called 'Hand Fish'. Pulse Qi flows from Shaoshang and overflows into Yuji, thus named Ying-spring. Pronounced 'jiong'.) Qi pours into Taiyuan. Taiyuan is located in the depression below the thenar eminence and belongs to the Shu-stream category. ('Shu' means to transport and gather. *Nanjing* (Classic of Difficult Issues) states: The Shu points of the Zang organs are where Qi of the San Jiao (Triple Burner) stagnates and accumulates. Thus, Lung Qi and San Jiao Qi are transported and gathered here, hence named Shu. [Ping An]: Taiyuan is written as "Taiquan" in *Lingshu* and *Jiayi Jing*; see previous notes. The character "xia" (below) is written as "yi cun" (one inch) in *Lingshu*; "shu" is written as "yu"; *Jiayi Jing* also writes it as "yu", not repeated below.) Qi travels through Jingqu. Jingqu is located at the Cun Kou (radial pulse position), pulsating without stopping, and belongs to the Jing-river category. (At Cun Kou, the twelve meridians pass through channels, hence named Jingqu. 'Ju' means stop. The Taiyin Lung meridian pulses continuously at Cun Kou, hence 'not stopping'. 'Jing' means passage; Lung Qi is constantly passing here, hence named Jing. [Ping An]: *Qianjin Fang* has the six characters "guoyu Lique wei yuan" (passing through Lieque as Yuan) before "Xing yu Jingqu".) Qi enters Chize. Chize is located at the arterial pulse in the center of the elbow crease and belongs to the He-sea category; it is the He-sea point of the Hand-Taiyin Lung Meridian. (Just as water flows from a well to merge with the sea, pulse Qi flows from the finger's Jing-well point and merges here with the Qi of its home organ, hence named He-sea. Explanations for the other ten Shu points follow this pattern. The names and meanings of all Shu points have been fully explained in *Mingtang*.)
The Pericardium (Hand-Shouyin) meridian's Jing-well point is Zhongchong. Zhongchong is located at the tip of the middle finger and belongs to the Jing-well category; Qi flows into Laogong. Laogong is located in the center of the palm, between the proximal phalanx of the middle finger and the palm, and belongs to the Ying-spring category. (*Mingtang* calls it the Five Star point; it is an arterial pulse in the palm. [Ping An]: *Jiayi Jing* writes "Xin" (Heart) as "Xinzhu" (Pericardium). *Lingshu* adds "mu" (Wood) after "jing" (well).) Qi pours into Daling. Daling is located in the depression below between the two bones behind the wrist and belongs to the Shu-stream category. [Ping An]: *Qianjin Fang* has the six characters "guoyu Neiguan wei yuan" (passing through Neiguan as Yuan) after "wei shu" (is Shu). "Liang gu zhi jian fang xia zhe ye" (that which is below between the two bones) is written as "Liang jian jian xian zhe zhong" (in the depression between the two tendons) in *Jiayi Jing*. Qi travels through Jianshi. Jianshi is located between the two tendons, three cun from the wrist; when there is pathology, Qi arrives here; when healthy, Qi stops here, and it belongs to the Jing-river category. (Fang xia means the depression. San cun zhi zhong means the vicinity of three cun. If there is deficiency or excess pathology, Qi is driven to this point; if no pathology, it does not reach, thus stopping. *Mingtang*, under this Hand-Shouyin meridian, lists the Five Shu points of the Hand-Shaoyin Heart meridian. This text states that the Heart does not accept pathogenic factors, so the Hand-Shaoyin meridian has no Shu points. [Ping An]: *Lingshu* adds the character "zhi" (of) after "dao" (pathway).) Qi enters Quze. Quze is located in the depression below the medial border of the elbow, obtained by flexing the arm, and belongs to the He-sea category; it is the He-sea point of the Hand-Shouyin (Pericardium) Meridian.
The Liver meridian's Jing-well point is Dadun. Dadun is located at the tip of the big toe and among the hair tuft, and belongs to the Jing-well category. (Both the tip of the big toe and the hair tuft refer to Dadun, the Jing-well point of the Jueyin meridian. [Ping An]: *Jiayi Jing* writes "qu er de zhi" (obtained by flexing) as "qu zhou de zhi" (obtained by flexing the elbow). *Lingshu* writes "Shouxin zhu" (Hand Pericardium) as "Shao Yin". *Lingshu* adds "mu" (Wood) after "jing" (well).) Qi flows into Xingjian. Xingjian is located between the big toe and the second toe and belongs to the Ying-spring category. (*Mingtang* records that the Foot-Jueyin Liver meridian pulse is palpable. [Ping An]: *Lingshu* adds the character "zu" (foot) before "dazhi" (big toe).) Qi pours into Taichong. Taichong is located in the depression two cun above Xingjian and belongs to the Shu-stream category. (*Mingtang* records it is in the depression two cun or one and a half cun distal to the metatarsophalangeal joint. [Ping An]: *Lingshu* lacks the characters "zhe" (that) and "er" (two) after "xingjian shang" (above Xingjian).) Qi travels through Zhongfeng. Zhongfeng is located in the depression one and a half cun anterior to the medial malleolus; if Qi flow is obstructed, it stagnates; if harmonized, it flows freely; it can be located by moving the foot, and belongs to the Jing-river category. (Qi movement is called 'shi'. 'Wan' means not extending, blocked. *Mingtang* records it is one cun anterior to the medial malleolus, taken with the foot dorsiflexed, in the depression. It is obtained by extending the foot. [Ping An]: *Qianjin Fang* has "guoyu Zhongfeng wei yuan, xing yu Zhong... wei jing" (passing through Zhongfeng as Yuan, traveling through Zhong... as Jing), which differs from this text.) Qi enters Ququan. Ququan is located below the fibular condyle and above the large tendon, obtained by flexing the knee, and belongs to the He-sea category; it is the He-sea point of the Foot-Jueyin Liver Meridian. (*Mingtang* records it is below the medial tibial condyle, above the large tendon, below the small tendon, in the depression.)
The Spleen meridian's Jing-well point is Yinbai. Yinbai is located at the medial tip of the big toe and belongs to the Jing-well category; Qi flows into Dadu. Dadu is located in the depression posterior to the first metatarsophalangeal joint and belongs to the Ying-spring category; Qi pours into Taibai. Taibai is located below the nuclear bone (first metatarsal head) and belongs to the Shu-stream category. (The nuclear bone is posterior to the big toe's proximal joint, anterior to the navicular tuberosity's prominence. 'He' sounds like 'jing ge fan'. [Ping An]: *Lingshu* adds "mu" (Wood) after "jing"; Dadu is written as "Tai Du". The character 'He' was mistakenly printed as 'wan' (wrist) in the Yuan edition; annotation same. Note: 'He' sounds like 'jing ge fan'; Yuan edition lacks these four characters.) Qi travels through Shangqiu. Shangqiu is located in the depression below the medial malleolus and belongs to the Jing-river category. (*Mingtang* records it is slightly anterior to the medial malleolus. [Ping An]: *Qianjin Fang* has the six characters "guoyu Gongsun wei yuan" (passing through Gongsun as Yuan) before "Xing yu Shangqiu".) Qi enters Yinlingquan. Yinlingquan is located in the depression below the tibial condyle, obtained by flexing and extending, and belongs to the He-sea category; it is the He-sea point of the Foot-Taiyin Spleen Meridian. (Below the medial tibial condyle of the knee. [Ping An]: *Lingshu* lacks "qu" (flex); below "Taiyin" lacks "jing" (meridian).)
The Kidney meridian's Jing-well point is Yongquan. Yongquan is located in the center of the sole of the foot and belongs to the Jing-well category. (*Mingtang* also calls it Dizhong. [Ping An]: Yongquan is written as "Xun Quan" in *Lingshu* and *Jiayi Jing*. *Lingshu* adds "mu" (Wood) after "jing" (well).) Qi flows into Ran Gu. Ran Gu is located below the calcaneal prominence (Ran Gu) and belongs to the Ying-spring category. (*Mingtang* also calls it Longquan, located in the depression below the large bone arising anterior to the medial malleolus. This large bone is the Ran Gu.) Qi pours into Taixi. Taixi is located in the depression posterior to the medial malleolus and superior to the calcaneus and belongs to the Shu-stream category. (*Mingtang* records the arterial pulse above the calcaneus. [Ping An]: *Lingshu* writes Taixi as "Da Xi"; "xian xia" lacks "zhe zhi" (that of). For Shu, *Qianjin Fang* has "guoyu Shuiquan wei yuan" (passing through Shuiquan as Yuan).) Qi travels through Fuliou. Fuliou is located two cun above the medial malleolus, pulsating continuously, and belongs to the Jing-river category. (*Mingtang* also calls it Changyang and Fubai; Foot-Shaoyin Kidney meridian, pulsating without rest. [Ping An]: Fuliou is written as "Fuliu" in *Jiayi Jing*. Above the ankle, *Lingshu* and *Jiayi Jing* add "nei" (inner). Below "er cun", *Jiayi Jing* adds "xian zhe zhong" (depression).) Qi enters Yingu. Yingu is located posterior to the tibial condyle, below the large tendon, and above the small tendon; it responds to pressure and is obtained by flexing the knee, and belongs to the He-sea category; it is the He-sea point of the Foot-Shaoyin Kidney Meridian. (*Mingtang* records it is posterior to the medial tibial condyle of the knee. 'An ying shou' means feeling a distinct sensation upon pressing.)
The Bladder meridian's Jing-well point is Zhiyin. Zhiyin is located at the tip of the little toe and belongs to the Jing-well category. (*Mingtang* records it is on the lateral side of the little toe, distance from the nail corner like the width of a leek leaf. [Ping An]: *Lingshu* adds "jin" (Metal) after "jing" (well).) Qi flows into Tonggu. Tonggu is located anterior to the proximal phalanx joint and belongs to the Ying-spring category. (*Mingtang* records Tonggu is in the depression anterior to the proximal phalanx joint on the lateral side of the little toe. [Ping An]: *Lingshu* adds "wai ce ye" (lateral side) after "qian" (anterior).) Qi pours into Shugu. Shugu is located posterior to the proximal phalanx joint and belongs to the Shu-stream category. (*Mingtang* records it is in the depression posterior to the proximal phalanx joint on the lateral side of the little toe. [Ping An]: *Lingshu* adds "xian zhe zhong" (depression) after "hou" (posterior).) Qi passes through Jinggu. Jinggu is located below the lateral malleolus and belongs to the Yuan-source category. (The vital qi below the navel is the root of human life and the foundation of the twelve meridians, hence named Yuan-source. The San Jiao is the special envoy of Yuan-source Qi, primarily transporting the Three Qi to manage the five Zang and six Fu organs. Thus, Yuan-source is a respectful title for the San Jiao, so all five Zang and six Fu organs have Yuan-source points. The Lung's Yuan-source emerges from Taiyuan; the Heart's from Daling; the Liver's from Taichong; the Spleen's from Taibai; the Kidney's from Taixi; the Hand-Shaoyin Heart meridian's Yuan-source emerges from Shenmen, at the tip of the radial styloid process behind the wrist. All these use the Shu-stream point as the Yuan-source because the Shu-stream is where Qi of the San Jiao stagnates and accumulates. The Yuan-source points of the six Fu organs: Gallbladder's emerges from Qiuxu; Stomach's from Chongyang; Large Intestine's from Hegu; Small Intestine's from Wanggu; Bladder's from Jinggu; San Jiao's from Yangchi. The six Fu organs are Yang; San Jiao travels through all Yang meridians, so one Shu point is named Yuan-source, not matching the Five Times. Thus, the Fu organs have six Shu points, sharing one Qi with the San Jiao. [Ping An]: *Lingshu* writes "wai huai" (lateral malleolus) as "wai ce da gu" (four characters: lateral side large bone). Yuan-source is written as "yuan" in *Qianjin Fang*, same below.) Qi travels through Kunlun. Kunlun is located posterior to the lateral malleolus and superior to the calcaneus and belongs to the Jing-river category; Qi enters Weizhong. Weizhong is located in the center of the popliteal fossa and belongs to the He-sea category; obtained by flexing the knee, it is the He-sea point of the Foot-Taiyang Bladder Meridian. (*Mingtang* records the arterial pulse in the center of the popliteal crease. [Ping An]: *Jiayi Jing* adds seven characters "xian zhong xi mai dong ying shou" (depression, fine pulse moves and responds to touch) after "zhi shang" (above). In *Lingshu*, "zhong ye" (center is) has "ye" written as "yang"; below "Taiyang" lacks "jing" (meridian).)
The Gallbladder meridian's Jing-well point is Qiaoyin. Qiaoyin is located at the tip of the fourth toe (little toe secondary toe) and belongs to the Jing-well category. (*Mingtang* records the tip of the fourth toe, distance from the nail corner like the width of a leek leaf. [Ping An]: *Lingshu* adds "jin" (Metal) after "jing" (well).) Qi flows into Xiaxi. Xiaxi is located between the fourth and fifth toes and belongs to the Ying-spring category. (*Mingtang* records in the depression anterior to the proximal phalanx joint between the divergent bones of the fourth and fifth toes. [Ping An]: *Lingshu* adds "zu" (foot) before "xiao zhi" (little toe).) Qi pours into Linqi. Linqi is located in the depression one and a half cun superiorly and belongs to the Shu-stream category. (*Mingtang* records in the depression between the skin of the proximal phalanx of the fourth and fifth toes, one and a half cun from Xiaxi. [Ping An]: *Jiayi Jing* writes "zhu pi jian" (note skin space) as "hou jian" (posterior space).) Qi passes through Qiuxu. Qiuxu is located in the depression below the lateral malleolus and belongs to the Yuan-source category. (*Mingtang* records in the depression below the lateral malleolus as described, three cun from Linqi. [Ping An]: Xu is written as "xu" in *Lingshu* and *Jiayi Jing*. Before "xia xian" (below depression), *Lingshu* adds "qian" (anterior). Note: Distance from Linqi three cun, *Jiayi Jing* writes "distance from Linqi one cun".) Qi travels through Yangfu. Yangfu is located above the lateral malleolus, anterior to the fibula, and at the end of the絕骨 (fibular neck), and belongs to the Jing-river category. (*Mingtang* lacks "ji" (and); ji means both places. [Ping An]: *Jiayi Jing* adds "si cun" (four cun) after "fu gu shang" (above fibula). Below "duan" (end), *Jiayi Jing* adds nine characters "ru qian san fen qu Qiuxu qi cun" (like anterior three fen, seven cun from Qiuxu).) Qi enters Yanglingquan. Yanglingquan is located in the depression lateral to the knee and belongs to the He-sea category; obtained by extending the foot, it is the He-sea point of the Foot-Shaoyang Gallbladder Meridian. (*Mingtang* records below the lateral border of the knee. [Ping An]: *Lingshu* writes "wai xi" (outer knee) as "zai xi" (at knee); below "shen" (extend) lacks "zu" (foot).)
The Stomach meridian's Jing-well point is Lidui. Lidui is located medially at the big toe and at the tip of the second toe and belongs to the Jing-well category. (*Mingtang* records distance from the nail corner like the width of a leek leaf. [Ping An]: *Lingshu* adds "jin" (Metal) after "jing" (well).) Qi flows into Neiting. Neiting is located in the depression between the lateral sides of the second and third toes and belongs to the Ying-spring category. (*Mingtang* records between the lateral sides of the big toe and second toe. [Ping An]: *Lingshu* lacks "xian zhe zhong" (depression) after "wai jian" (lateral space).) Qi pours into Xangu. Xangu is located in the depression two cun superiorly between the medial spaces of the middle toes (referring to the web between the second and third toes) and belongs to the Shu-stream category. (*Mingtang* records in the depression between the skin of the proximal phalanx on the lateral side of the big toe and second toe, two cun from Neiting. [Ping An]: *Lingshu* adds "shang" (superior) after "Xangu zhe" (Xangu is). Note: Pi character, *Jiayi Jing* writes "hou" (posterior).) Qi passes through Chongyang. Chongyang is located in the depression five cun above the dorsum of the foot and belongs to the Yuan-source category; obtained by moving the foot. (*Mingtang* also called Huiyuan, arterial pulse above the bone between the five cun on the dorsum of the foot, three cun from Xangu. [Ping An]: Fu is written as "Fu" in *Jiayi Jing*.) Qi travels through JieXi. JieXi is located in the depression one and a half cun above Chongyang and belongs to the Jing-river category. (*Mingtang* records one and a half cun posterior to Chongyang at the ankle.) Qi enters Xialing. Xialing is located three cun below the knee, specifically Zusanli on the lateral side of the tibia, and belongs to the He-sea category; another three cun down is Juliu Shanglian (Upper Edge of Giant Void); another three cun down is Juliu Xialian (Lower Edge of Giant Void). The Large Intestine's Qi attaches to the upper edge, the Small Intestine's Qi attaches to the lower edge; this is the Foot-Yangming Stomach Meridian. The Large Intestine and Small Intestine both attach to this; it is the Foot-Yangming Meridian. (Human knees resemble hills; three cun below the hill, one cun is one li. Below Zusanli, at the upper and lower boundaries of the three cun section, the upper boundary is Shanglian, the lower is Xialian. Because it is on the lateral side of the tibia, it is named Lian. The Foot-Yangming meridian travels through this void; Large Intestine Qi merges with Yangming at Shanglian, Small Intestine Qi merges with Yangming at Xialian, hence saying Large Intestine attaches to upper, Small Intestine to lower. [Ping An]: *Lingshu* adds "gu" (bone) after "". Below the first "fu xia" (again below), there are "san li" (three li); below the second "fu xia", there are "shang lian" (upper edge). "Jie shuyu ci" is written as "jie shuyu wei" (all attach to stomach).)
The San Jiao (Triple Burner) meridian combines superiorly with the Hand-Shaoyang San Jiao Meridian. Its Jing-well point is Guanchong. Guanchong is located at the tip of the ring finger (fourth finger) and belongs to the Jing-well category; Qi flows into Yemen. Yemen is located between the ring and little fingers and belongs to the Ying-spring category; Qi pours into Zhongzhu. Zhongzhu is located posterior to the proximal phalanx joint and belongs to the Shu-stream category; Qi passes through Yangchi. Yangchi is located in the depression above the wrist and belongs to the Yuan-source category. (Yangchi, *Mingtang* also called Bieyang, located in the depression above the wrist on the dorsal aspect. [Ping An]: *Lingshu* adds "jin" (Metal) after "jing"; Yemen is written as "Yemen" in *Lingshu* and "Ye" in *Jiayi Jing*. Before "zhi jian" (between), *Lingshu* adds "ci zhi" (secondary finger); after "zhi hou" (after joint), *Lingshu* adds "xian zhong zhe" (depression).) Qi travels through Zhigou. Zhigou is located in the depression between the two bones three cun above the wrist and belongs to the Jing-river category; Qi enters Tianjing. Tianjing is located in the depression above the lateral epicondyle of the humerus and belongs to the He-sea category; obtained by flexing the elbow. (*Mingtang* records posterior to the lateral epicondyle of the humerus, in the depression between the two tendons one cun behind the elbow. [Ping An]: *Lingshu* writes "wan shang" (above wrist) as "shang wan" (upper wrist); "er de zhi" (and obtained) as "nai de zhi" (then obtained).) The inferior He-sea point of the San Jiao is located anterior to the Foot-Taiyang meridian and posterior to the Foot-Shaoyang meridian, emerging at the lateral margin of the popliteal fossa, named Weiyang. This is the collateral vessel of the Taiyang meridian and the inferior He-sea point of the Hand-Shaoyang San Jiao Meridian. (Superior Jiao is like mist, Middle Jiao is like fermentation, Inferior Jiao is like a drain. The Qi of these three Jiaos communicates up and down. Thus, the superior He-sea is at the back, one and a half cun lateral to the spinous process of the 13th thoracic vertebra. The inferior He-sea is here, between the Taiyang meridian, emerging at the lateral margin of the popliteal fossa into the Foot-Taiyang collateral. Where San Jiao Qi gathers as it descends, hence named inferior He-sea. [Ping An]: *Lingshu* writes "zu tai yang" (Foot-Taiyang) as "zu da zhi" (Foot-big toe).) The Foot-San Jiao is commanded by the Taiyang meridian; it is a branch of the Taiyang meridian. Ascending five cun above the ankle, it branches off, penetrates the gastrocnemius muscle, emerges at Weiyang, joins the main channel of the Taiyang meridian, enters the abdomen to connect with the Bladder and Inferior Jiao. (Gastrocnemius, sound "chuan mian fan". Vital Qi in the kidney region: Foot-Taiyang takes Yuan-source Qi as a special envoy to guide San Jiao Qi. It emerges at the depression between red and white flesh below the large bone of the lateral foot as the Yuan-source point, ascends five cun above the ankle, branches off to penetrate the gastrocnemius, emerges at Weiyang, joins the main channel of Taiyang, enters the abdomen to connect with the Bladder. The Inferior Jiao is the Bladder. Yuan-source Qi connects with the Bladder via Taiyang, regulating the Bladder to ensure normal urination. Because this San Jiao Yuan-source Qi travels through the foot, it is named Foot-San Jiao. [Ping An]: *Lingshu* lacks "zu" (foot) before "San Jiao"; "tai yang zhi suo jiang" is written as "shao yang tai yin zhi suo jiang" (commanded by Shaoyang and Taiyin), note says: one version writes "tai yang".) When full/excess, there is urinary retention; when deficient, there is enuresis. Enuresis is treated with tonification; urinary retention is treated with sedation.
The Small Intestine meridian combines superiorly with the Hand-Taiyang Small Intestine Meridian. Its Jing-well point is Shaoze. Shaoze is located at the tip of the little finger and belongs to the Jing-well category. (*Mingtang* also called Shaoji, one fen below the nail corner in the depression. [Ping An]: *Lingshu* writes "sheng" (full) as "shi" (excess); before "Xiao Chang" (Small Intestine) adds "Shou Tai Yang" (Hand-Taiyang); *Lingshu* adds "jin" (Metal) after "jing" (well).) Qi flows into Qian Gu. Qian Gu is located in the depression anterior to the proximal phalanx joint of the little finger and belongs to the Ying-spring category. (*Mingtang* records in the center of the lateral side of the little finger. [Ping An]: *Lingshu* writes "xiao zhi" (little finger) as "wai lian" (lateral border).) Qi pours into Houxi. Houxi is located posterior to the proximal phalanx joint and belongs to the Shu-stream category. (*Mingtang* records in the depression posterior to the proximal phalanx joint on the lateral side of the little finger. [Ping An]: *Lingshu* adds "zai shou wai ce" (on the lateral side of the hand) before "ben jie" (proximal joint).) Qi passes through Wangu. Wangu is located anterior to the carpal bone on the lateral side of the hand and belongs to the Yuan-source category. (*Mingtang* records in the depression below the bone arising anterior to the wrist on the lateral side of the hand. This arising bone is the carpal bone; this meridian names it Wangu. Wang, sound "hu duan fan". [Ping An]: Wangu is written as "Wangu" (Carpal Bone) in *Lingshu* and *Jiayi Jing*. Qi travels through Yanggu. Yanggu is located in the depression below the ulnar styloid process (Dui Gu) and belongs to the Jing-river category. (*Mingtang* records below the Dui Gu in the wrist on the lateral side of the hand. [Ping An]:
