阴跷亦起于跟中，少阴之别内踝行，上循阴股入胸腹，上至咽喉至睛明。
【注】阴跷之脉，亦起于跟中，由少阴别脉然谷之穴，上内联踝，循阴股，入胸腹，上
至咽喉、睛明穴，亦会于太阳也。

阴跷起于然谷穴，上行照海交信列，三穴原本足少阴，足之太阳睛明接。
阴跷脉起足少阴，足内踝前然谷寻，踝下一寸照海陷，踝上二寸交信真，目内 外
宛中取，睛明一穴甚分明。
【注】阴跷者，以其所行阴经，为足少阴之别脉也。起于足少阴肾经，足内踝前大骨
下陷中，然谷穴也。从然谷穴循内踝之下一寸，照海穴也。从照海穴不循太溪穴，又
于足内踝之上二寸直行交信穴。从交信穴上循阴股，入阴而行，上循胸里入缺盆，上出
人迎之前，入 鼻旁，属目内 外宛宛中睛明穴，合于太阳、阳跷，上行气并相还，则为
濡目之用矣。故知阴跷脉气，若不与阳跷脉气并荣于目，则目不能合也。此阴跷循行之经脉也。

《二十八难》曰∶阳维阴维者，维络于身，溢蓄不能环流，灌溢诸经者也。故阳维起于
诸阳之会，阴维起于诸阴交也。
阳维脉起足太阳，外踝之下金门疆，从 背肩项面头，维络诸阳会督场。
【注】阳维之脉，起于足太阳经外踝之下金门穴也。从 骨、背外、肩胛、项旁、面上、
头后至哑门穴，维络诸阳会于督脉也。

The Yin Qiao Mai (Yin Heel Vessel) also originates from the middle of the heel. It is a collateral branch of the Foot-Shaoyin Kidney Meridian, ascending along the medial malleolus, following the medial aspect of the thigh into the chest and abdomen, rising to the throat, and terminating at Jingming (BL1).
[Note] The Yin Qiao Mai also originates from the middle of the heel. Branching from the collateral of the Foot-Shaoyin Meridian at the point Rangu (KI2), it ascends to connect with the medial malleolus, follows the medial thigh, enters the chest and abdomen, rises to the throat and Jingming (BL1), and also intersects with the Taiyang Meridian.
The Yin Qiao Mai originates at Rangu (KI2), ascending through Zhaohai (KI6) and Jiaoxin (KI8). These three points originally belong to the Foot-Shaoyin Kidney Meridian, and finally connect at Jingming (BL1) of the Foot-Taiyang Bladder Meridian.
The Yin Qiao Mai originates from the Foot-Shaoyin Kidney Meridian; locate Rangu (KI2) anterior to the medial malleolus on the foot. One cun below the medial malleolus in the depression is Zhaohai (KI6); two cun above the medial malleolus is Jiaoxin (KI8). At the lateral side of the inner canthus, in the depression, lies Jingming (BL1), which is very distinct.
[Note] The Yin Qiao Mai, because it travels along the Yin meridians, is a collateral branch of the Foot-Shaoyin Kidney Meridian. It originates from the Foot-Shaoyin Kidney Meridian, in the depression anterior to the medial malleolus below the large bone, which is the point Rangu (KI2). From Rangu, it follows one cun below the medial malleolus, where Zhaohai (KI6) is located. From Zhaohai, bypassing Taixi (KI3), it ascends directly to Jiaoxin (KI8), two cun above the medial malleolus. From Jiaoxin, it ascends along the medial thigh, enters the yin region, ascends through the interior of the chest to the Supraclavicular Fossa (Quepen), emerges anterior to Renying (ST9), enters beside the nose, and belongs to the depression at the lateral side of the inner canthus, the point Jingming (BL1). It merges with the Taiyang and Yang Qiao Mai vessels. Ascending, their Qi moves together and returns, serving the function of moistening the eyes. Thus, it is known that if the Qi of the Yin Qiao Mai does not flourish together with the Qi of the Yang Qiao Mai in the eyes, the eyes cannot close. This is the pathway of the Yin Qiao Mai.
Nan Jing (Classic of Difficult Issues), Chapter 28, states: The Yang Wei Mai (Yang Linking Vessel) and Yin Wei Mai (Yin Linking Vessel) link and network the body. When Qi and Blood overflow and accumulate, unable to circulate in a ring, they pour into and irrigate all the meridians. Therefore, the Yang Wei Mai originates from the meeting point of all Yang meridians, and the Yin Wei Mai originates from the intersection of all Yin meridians.
The Yang Wei Mai originates from the Foot-Taiyang Bladder Meridian, at Jinmen (BL63) below the lateral malleolus. It travels along the back, shoulders, neck, face, and head, linking all Yang meridians and meeting at the Du Mai (Governing Vessel).
[Note] The Yang Wei Mai originates from Jinmen (BL63) below the lateral malleolus of the Foot-Taiyang Bladder Meridian. From the fibula, the lateral back, scapula, neck, face, and head posteriorly to Yamen (GV15), it links all Yang meridians and meets at the Du Mai (Governing Vessel).
