《素问》说：人体的常规规律是，太阳经通常多血少气，少阳经通常少血多气，阳明经通常多气少血，少阴经通常少血多气，厥阴经通常多血少气，太阴经通常多气少血。这是上天的常数。（此处“天”字恐为“人”字之误）（新校正注云：《甲乙经·十二经水篇》中，血气多少与《素问》不同，认为太阳经多血多气，太阴经多血少气。）足太阳经与足少阴经互为表里，足少阳经与足厥阴经互为表里，足阳明经与足太阴经互为表里，这称为足部的阴阳关系。手太阳经与手少阴经互为表里，手少阳经与手厥阴心主经互为表里，手阳明经与手太阴经互为表里，这称为手部的阴阳关系。
《难经》说：经脉，是运行血气、沟通阴阳，以滋养全身的组织。其气血运行始于中焦，注入手太阴肺经和手阳明大肠经；手阳明大肠经注入足阳明胃经和足太阴脾经；足太阴脾经注入手少阴心经和手太阳小肠经；手太阳小肠经注入足太阳膀胱经和足少阴肾经；足少阴肾经注入手厥阴心包经和手少阳三焦经；手少阳三焦经注入足少阳胆经和足厥阴肝经；足厥阴肝经又回流注入手太阴肺经。
《医种子》说：足三阴经在胸腹部没有脉气分布，《铜人腧穴针灸图经》强行将其归为阴经，是不对的。然而，手部的阴经从腋下发出，足部的阴经从大腿内侧进入体内。所谓“入”，是指进入腹内，因此能属络脏腑，向上穿过膈肌，夹行于咽喉，连接舌根，深入脑部，并非仅在皮肤肌肉之外。绘制经络图的人，被《甲乙经》迷惑，强行将膺俞、胸俞、冲脉的穴位归属于足三阴经，认为是脉气所发之处，《十四经发挥》更是谬误严重，真是千古长夜般的错误啊。遍考《阴阳离合论》、《气府论》、《气穴论》、《经脉篇》、《经别篇》等篇章，深知所列出的这些穴位，确实不属于阴经，故将其列出并加以说明。
（左右共二十二个穴位）
《经脉篇》说：肺，是手太阴肺经所属。其经脉起始于中焦，向下联络大肠，回绕沿着胃的上口，向上穿过膈肌，属于肺脏。从肺系（气管、喉咙等）横向出于腋下。（云门穴、中府穴）向下沿手臂内侧前缘。（天府穴、侠白穴）行于手少阴心经和手厥阴心包经之前，下行至肘窝中。（尺泽穴）沿前臂内侧桡骨下缘。（孔最穴）进入寸口。（经渠穴、太渊穴）上行至大鱼际，沿鱼际边缘。（即鱼际穴）出于大拇指末端。（少商穴）其支脉从腕后（列缺穴）直出，行至食指内侧边缘，出于其末端。
又说：手太阴肺经的络穴名叫列缺，起始于腕上分肉之间，与手太阴肺经并行，直接进入掌中，散布于鱼际处。○取穴时距离腕横纹半寸。（马莳说：半寸，应当是一寸半。）该络脉别走入手阳明大肠经。
《经别篇》说：手太阴肺经的正经，别行进入渊腋穴附近、手少阴心经之前，进入体内走向肺脏，散布联络大肠，向上出于缺盆，循行于喉咙，与手阳明大肠经相会合。
《缪刺论》说：邪气客居于手足少阴、手太阴、足阳明这五条络脉。这五条络脉都交会于耳中，向上联络左额角。
《邪客篇》说：手太阴肺经的经脉，出于大拇指末端，向内屈曲，沿白肉际（手掌侧边缘），到达本节之后方的太渊穴，停留以充盛脉气，向外屈曲上行至本节下方，向内屈曲与诸阴络脉会合于鱼际。多条脉气同时注入，其气滑利，伏行于壅骨之下，向外屈曲出于寸口而行，向上至于肘部内侧边缘，进入大筋之下，向内屈曲上行至阴分，进入腋下，向内屈曲走向肺脏。这是顺行逆数之屈折变化。
《经筋篇》说：手太阴肺经的经筋，起始于大拇指上方，沿手指上行，结聚于鱼际后方，行于寸口外侧，向上沿前臂，结聚于肘中，向上沿内侧边缘，进入腋下，出于缺盆，结聚于肩前部，向上结聚于缺盆，向下结聚于胸里，分散贯穿贲门，与贲门相合，向下抵住季胁。

少商穴（手太阴肺经脉之所出，即井穴。）
按《千金方》记载，有中府穴属于手阳明大肠经之会。注解说：《铜人腧穴针灸图经》认为中府穴属三焦经。《外台秘要》无中府、云门二穴的记录（将其归入脾经）。程衍道说：这是论述经脉循行而非归属本经穴位。《穴法折衷》说：各家都认为本经穴位始于中府。《标幽赋》、《蠡海集》、《锦囊秘录》都说：本经穴位始于云门。如今考证其经脉循行的态势，以云门穴为起始点是正确的。
As stated in the *Suwen* (Basic Questions): The constant pattern of the human body is that the Taiyang channels usually have abundant blood and deficient qi, the Shaoyang channels usually have deficient blood and abundant qi, the Yangming channels usually have abundant qi and deficient blood, the Shaoyin channels usually have deficient blood and abundant qi, the Jueyin channels usually have abundant blood and deficient qi, and the Taiyin channels usually have abundant qi and deficient blood. This is the natural constant. (The character "Tian" [Heaven] here is likely a typo for "Ren" [Human].) (The New Correction notes: In the *Jiayi Jing* [Systematic Classic of Acupuncture and Moxibustion], Chapter on the Twelve Channels of Water, the amounts of blood and qi differ from the *Suwen*; it states that the Taiyang channel has abundant blood and abundant qi, and the Taiyin channel has abundant blood and deficient qi.) The Foot-Taiyang channel and the Foot-Shaoyin channel are exterior-interior partners; the Foot-Shaoyang channel and the Foot-Jueyin channel are exterior-interior partners; the Foot-Yangming channel and the Foot-Taiyin channel are exterior-interior partners. These constitute the Yin-Yang relationships of the lower limbs. The Hand-Taiyang channel and the Hand-Shaoyin channel are exterior-interior partners; the Hand-Shaoyang channel and the Hand-Jueyin Pericardium channel are exterior-interior partners; the Hand-Yangming channel and the Hand-Taiyin channel are exterior-interior partners. These constitute the Yin-Yang relationships of the upper limbs.
As stated in the *Nanjing* (Classic of Difficult Issues): The meridians (channels) transport blood and qi, connect Yin and Yang, and thereby nourish the body. Their circulation begins at the Middle Jiao (Middle Burner), flowing into the Hand-Taiyin Lung channel and the Hand-Yangming Large Intestine channel; the Hand-Yangming Large Intestine channel flows into the Foot-Yangming Stomach channel and the Foot-Taiyin Spleen channel; the Foot-Taiyin Spleen channel flows into the Hand-Shaoyin Heart channel and the Hand-Taiyang Small Intestine channel; the Hand-Taiyang Small Intestine channel flows into the Foot-Taiyang Bladder channel and the Foot-Shaoyin Kidney channel; the Foot-Shaoyin Kidney channel flows into the Hand-Jueyin Pericardium channel and the Hand-Shaoyang Sanjiao channel; the Hand-Shaoyang Sanjiao channel flows into the Foot-Shaoyang Gallbladder channel and the Foot-Jueyin Liver channel; the Foot-Jueyin Liver channel then returns to flow into the Hand-Taiyin Lung channel.
According to *Yi Zhongzi* (Seed of Medicine): The three Foot-Yin channels do not have pulse distributions in the chest and abdomen. The *Tongren* [Bronze Man] diagrams forcibly categorize them as Yin channels, which is incorrect. However, the Yin channels of the hands emerge from the axilla, while the Yin channels of the feet enter from the thigh. To "enter" means to enter the abdominal cavity; thus, they can associate with the Zang organs and link with the Fu organs. They ascend through the diaphragm, flank the pharynx, connect to the root of the tongue, and enter the brain. They are not merely located outside the skin and muscles. Those who draw meridian maps, confused by the *Jiayi Jing*, forcibly attribute acupoints such as Ying Shu, Xiong Shu, and those of the Chong Mai (Penetrating Vessel) to the three Foot-Yin channels, claiming they are sites where meridian qi emerges. The *Shisi Jing Fa Hui* (Elucidation of the Fourteen Meridians) is particularly erroneous, representing a long night of ignorance for millennia. Having thoroughly examined chapters such as *Yin Yang Li He Lun* (Discourse on the Separation and Combination of Yin and Yang), *Qi Fu Lun* (Discourse on Qi Houses), *Qi Xue Lun* (Discourse on Qi Acupoints), *Jing Mai Pian* (Chapter on Meridians), and *Jing Bie Pian* (Chapter on Extraordinary Meridians), I deeply understand that the listed acupoints indeed do not belong to the Yin channels. Therefore, I list them explicitly to clarify this point.
(There are twenty-two acupoints on the left and right sides combined.)
The *Jing Mai Pian* (Chapter on Meridians) states: The Lung belongs to the Hand-Taiyin Lung channel. Its meridian originates in the Middle Jiao, descends to connect with the Large Intestine, circles back along the upper opening of the stomach, ascends through the diaphragm, and enters to belong to the Lung. From the lung system (trachea and larynx), it emerges horizontally from the axilla. (Yunmen [Cloud Gate], Zhongfu [Central Palace]) It descends along the medial aspect of the arm. (Tianfu [Heavenly Granary], Xiabai [Hero's White]) It runs anterior to the Hand-Shaoyin Heart and Hand-Jueyin Pericardium channels, descends to the midpoint of the elbow. (Chize [Cistern of the Dragon]) It follows the inner border of the forearm, below the radius. (Kongzui [Palace of Leaks]) It enters the Cun Kou (Radial Pulse). (Jingqu [Water Course], Taiyuan [Great Abyss]) It ascends over the Thenar eminence, following its border. (That is Yuji [Fish Border]) It emerges at the tip of the thumb. (Shaoshang [Little Shang]) Its branch arises from behind the wrist (Lieque [Broken Apart]), goes straight out to the medial border of the index finger, and emerges at its tip.
It also states: The Luo-connecting vessel of the Hand-Taiyin channel is named Lieque. It originates between the flesh layers above the wrist, runs parallel to the Hand-Taiyin channel, directly enters the palm, and scatters into the thenar eminence. ○ When selecting this point, measure half cun from the wrist crease. (Ma Shi says: Half cun should be read as one and a half cun.) It branches off to connect with the Yangming channel.
The *Jing Bie Pian* (Chapter on Extraordinary Meridians) states: The Zheng-meridian of the Hand-Taiyin diverges and enters anterior to Yuan Ye and the Hand-Shaoyin channel, enters internally to travel to the Lung, scatters to connect with the Large Intestine, emerges superiorly at Quepen, follows the throat, and combines with the Yangming channel.
The *Miao Ci Lun* (Discourse on Miraculous Puncture) states: Pathogenic factors invade the collaterals of the Hand-Shaoyin, Hand-Taiyin, and Foot-Yangming. These five collaterals all converge in the ear, ascending to connect with the left corner of the head.
The *Xie Ke Pian* (Chapter on Invasion by Pathogens) states: The meridian of the Hand-Taiyin emerges from the tip of the thumb, curves inward, follows the white flesh margin (the palmar side edge), reaches the posterior aspect of the proximal phalanx at Taiyuan, stays there to nourish the pulse, curves outward and upward below the proximal phalanx, curves inward to meet with various Yin collaterals at the thenar eminence. Multiple pulses inject simultaneously; their qi is smooth and rapid, running deep beneath the Yonggu bone, curving outward to emerge at the Cun Kou and proceed. It ascends to the medial border of the elbow, enters beneath the large tendon, curves inward and ascends to the Yin regions, enters the axilla, and curves inward to travel to the Lung. This represents the bending and folding of forward circulation and reverse counting.
The *Jing Jin Pian* (Chapter on Sinew Channels) states: The sinew channel of the Hand-Taiyin originates above the thumb, ascends along the finger, knots at the rear of the thenar eminence, runs along the lateral aspect of the Cun Kou, ascends along the arm, knots at the elbow, ascends along the medial border, enters the axilla, emerges at Quepen, knots at the anterior shoulder, ascends to knot at Quepen, descends to knot in the interior of the chest, scatters and penetrates the贲 (BEN - cardia/gastric region), combining with the BEN, descending to reach the hypochondrium.
Zhongfu (Meeting point of the Hand-Taiyin. ○ *Qi Xue Lun* New Correction states: Meeting point of the Hand and Foot Taiyin. Same as *Lei Jing*.)
Yunmen (Site where the Qi of the Hand-Taiyin Lung emerges.)
Tianfu (Same as above.)
Xiabai (Extraordinary connection of the Hand-Taiyin.)
Chize (Where the Hand-Taiyin enters, i.e., He-Sea point.)
Kongzui (Xi-Cleft point of the Hand-Taiyin.)
Lieque (Branches off to connect with the Yangming channel.)
Jingqu (Where the Hand-Taiyin travels, i.e., Jing-River point.)
Taiyuan (Where the Hand-Taiyin pulse injects, i.e., Shu-Stream and Yuan-Source point.)
Yuji (Where the Hand-Taiyin pulse flows, i.e., Ying-Spring point. ○ *Shengji Zonglu* states: Where it flows.)
Shaoshang (Where the Hand-Taiyin pulse exits, i.e., Jing-Well point.)
According to the *Qianjin Fang* (Thousand Gold Formulas), there is a meeting point belonging to the Hand-Yangming Large Intestine channel. The commentary notes: The *Tongren* attributes it to the Sanjiao channel. The *Waitai Mi Yao* (Essential Prescriptions Worth a Thousand Gold for Emergencies) does not record the Zhongfu and Yunmen points (classifying them under the Spleen channel). Cheng Yandao states: This discusses the course of the meridian rather than attributing points to the channel. *Xuefa Zhezhong* (Compromise of Acupoint Methods) states: All schools consider the points of this channel to begin at Zhongfu. The *Biao You Fu* (Marking the Profound Ode), *Lihai Ji*, and *Jinnang Milu* all state that the points of this channel begin at Yunmen. Upon examining the trend of meridian circulation, it is correct to regard Yunmen as the starting point.
