《灵枢·经脉别篇》曰∶足少阴上至 中，别走太阳而合，上至肾，当十四椎，出属带脉。

《二十八难》曰∶带脉者，起于季胁，回身一周。
带脉足少阴经脉，上 别走太阳经，合肾十四椎属带，起于季胁绕身行。
【注】带脉本由足少阴经之脉，上至 中，别走太阳而合肾，当十四椎，出属带脉，故
起于季胁，绕身一周行也。
带起少阳带脉穴，绕行五枢维道间，京门之下居 上，周回季胁束带然。
【注】足少阴之正脉，出于然谷，循内踝后。其别者入跟中，上 内，至 中，别走
而合太阳，上至肾之气穴穴，当十四椎内，与足少阴冲脉会，外与足少阳带脉合会，而不
与冲脉偕行，出于季胁，属少阳带脉穴也。故《难经》曰∶带脉者，起于季胁也。回身一周
者。谓起于足少阳带脉穴，循行五枢穴、维道穴，不行居 穴，回行如带，故曰带脉也。
带脉部分足少阳，季胁寸八是其乡，由带三寸五枢穴，过章五三维道当。
【注】带脉部分，在足少阳经季胁之下一寸八分，即带脉穴也。从带脉穴下三寸，即
五枢穴也。从五枢下行，过肝经之章门穴下五寸三分，即维道穴也。

《灵枢·脉度篇》曰∶跷脉者，少阴之别，起于然谷之后，上内踝之上，直上循阴股，入
阴，上循胸里，入缺盆，上出人迎之前，入 ，属目内 ，合于太阳、阳跷而上行。气并
相还，则为濡目，目气不荣，则目不合。

《二十八难》曰∶阳跷脉者，起于跟中，
循外踝上行，入风池；阴跷脉者，亦起于跟中，循内踝上行，至咽喉交贯冲脉。
《灵枢·经脉别篇》说：足少阴肾经向上到达膻中部位，分支走向太阳经并与其汇合，再向上到达肾脏，位于第十四椎骨处，外出归属于带脉。

《难经·第二十八难》说：带脉，起始于季胁（侧肋下部），环绕身体一周。
带脉与足少阴经脉相连，上行至膻中后分支走向太阳经，与肾脏及第十四椎骨处的带脉相合，起始于季胁，环绕身体一周运行。
【注释】带脉原本是由足少阴经的脉气，向上到达膻中部位，分支走向太阳经并与之汇合，再向上到达肾脏，正当第十四椎骨处，外出归属于带脉，所以起始于季胁，环绕身体一周运行。
带脉起始于足少阳胆经的带脉穴，在五枢穴和维道穴之间绕行，位于京门穴下方的髂嵴上，环绕季胁如同束带一般。
【注释】足少阴经的正脉，出于然谷穴，沿内踝后方上行。其分支进入脚跟中部，上行至小腿内侧，到达大腿根部，分支走向太阳经并与之汇合，向上到达肾脏的气穴处，正当第十四椎骨内侧，与足少阴冲脉会合，外部与足少阳胆经的带脉会合，而不与冲脉并行，出于季胁，归属于足少阳胆经的带脉穴。所以《难经》说：带脉起始于季胁。所谓“环绕身体一周”，是指起始于足少阳胆经的带脉穴，循行经过五枢穴、维道穴，不经过居髎穴，环绕运行如同腰带，所以称为带脉。
带脉属于足少阳胆经的一部分，在季胁下一寸八分的地方是其所在之处，从带脉穴向下三寸是五枢穴，经过章门穴下方五寸三分的位置是维道穴。
【注释】带脉的部分，位于足少阳胆经季胁穴下方一寸八分处，即是带脉穴。从带脉穴向下三寸，即是五枢穴。从五枢穴向下行，经过肝经章门穴下方五寸三分处，即是维道穴。

《灵枢·脉度篇》说：跷脉，是足少阴肾经的别络，起始于然谷穴之后，向上经过内踝上方，直上沿大腿内侧，进入阴部，向上沿胸部内部，进入缺盆，向上出人迎穴之前，进入目内眦，归属于目内眦，与太阳经、阳跷脉汇合并向上运行。气血并行相互返还，就能滋润眼睛，如果眼部的精气不能滋养，则眼睛无法闭合。

《难经·第二十八难》说：阳跷脉，起始于脚跟中部，沿外踝向上行，进入风池穴；阴跷脉，也起始于脚跟中部，沿内踝向上行，到达咽喉部并与冲脉交叉贯穿。
The *Ling Shu: Bie Pian of the Meridians* states: The Foot-Shaoyin (Kidney) meridian ascends to the chest center, sends a branch to the Taiyang meridian where they join, ascends further to the Kidney, at the level of the fourteenth thoracic vertebra, and emerges to connect with the Dai Mai (Girdle Vessel).

The *Nan Jing: Difficult Issue 28* states: The Dai Mai (Girdle Vessel) originates from the hypochondrium (lateral costal region) and encircles the body once.
The Dai Mai connects with the Foot-Shaoyin meridian; ascending to the chest center, it branches to the Taiyang meridian, joins with the Kidney and the Dai Mai at the fourteenth thoracic vertebra, originates from the hypochondrium, and circulates around the body in one loop.
[Annotation] The Dai Mai originally stems from the Qi of the Foot-Shaoyin meridian, ascending to the chest center, sending a branch to the Taiyang meridian to join, ascending to the Kidney, at the level of the fourteenth thoracic vertebra, emerging to connect with the Dai Mai. Therefore, it originates from the hypochondrium and circulates around the body in one loop.
The Dai Mai originates from the Dai Mai acupoint of the Foot-Shaoyang (Gallbladder) meridian, winding between the Wushu and Weidao acupoints, located below the Jingmen acupoint on the iliac crest, encircling the hypochondrium like a girdle.
[Annotation] The principal collateral of the Foot-Shaoyin meridian emerges from the Ran Gu acupoint, following the posterior aspect of the medial malleolus. Its branch enters the heel, ascends along the medial aspect of the lower leg, reaches the thigh root, branches to the Taiyang meridian and joins it, ascends to the Qi Xue of the Kidney, inside the fourteenth thoracic vertebra, meeting the Chong Mai (Penetrating Vessel) of the Foot-Shaoyin meridian. Externally, it meets the Dai Mai of the Foot-Shaoyang meridian, without traveling together with the Chong Mai, emerging from the hypochondrium, and connecting to the Dai Mai acupoint of the Foot-Shaoyang meridian. Thus, the *Nan Jing* states: "The Dai Mai originates from the hypochondrium." The phrase "encircles the body once" refers to originating from the Dai Mai acupoint of the Foot-Shaoyang meridian, circulating through the Wushu and Weidao acupoints, not passing through the Juliao acupoint, circling like a belt, hence named Dai Mai (Girdle Vessel).
A portion of the Dai Mai belongs to the Foot-Shaoyang meridian; its location is one cun and eight fen below the Jixie acupoint in the hypochondrium. Three cun below the Dai Mai acupoint is the Wushu acupoint. Descending from Wushu, passing five cun and three fen below the Zhangmen acupoint of the Liver meridian is the Weidao acupoint.
[Annotation] The part of the Dai Mai is located one cun and eight fen below the Jixie acupoint of the Foot-Shaoyang meridian, which is the Dai Mai acupoint itself. Three cun below the Dai Mai acupoint is the Wushu acupoint. Descending from Wushu, passing five cun and three fen below the Zhangmen acupoint of the Liver meridian is the Weidao acupoint.

The *Ling Shu: Mai Du Pian* states: The Qiao Mai (Heel Vessels) are the collaterals of the Foot-Shaoyin meridian, originating behind the Ran Gu acupoint, ascending above the medial malleolus, going straight up along the medial aspect of the thigh, entering the genital region, ascending along the interior of the chest, entering the Keyuan (Clavicular Fossa), ascending anterior to the Yingchang acupoint, entering the inner canthus, connecting to the inner canthus, joining with the Taiyang and Yang Qiao meridians to ascend. When Qi and Blood circulate together and return, they moisten the eyes; if the eye Qi fails to nourish, the eyes cannot close.
[Image: Yang Qiao Mai Circulation Diagram]
The *Nan Jing: Difficult Issue 28* states: The Yang Qiao Mai (Yang Heel Vessel) originates in the middle of the heel, ascends along the lateral malleolus, and enters the Fengchi acupoint; the Yin Qiao Mai (Yin Heel Vessel) also originates in the middle of the heel, ascends along the medial malleolus, reaches the throat, and intersects with the Chong Mai (Penetrating Vessel).
