《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。

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.

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).
