Section Eight: Three Yin Meridians
The Three Yin Meridians consist of the Shao Yin, Jue Yin, Tai Yin, and Yin Qiao.
The Yin Qiao Meridian originates from the center of the heel (Di Jin), behind the Ren Gu point of the Foot Shao Yin (Ren Gu is the root of the Yin Qiao. Rubbing Ren Gu is like fire; what fear is there of the Yin organ not rising?), then follows the Shao Yin to the inner ankle and goes to the Zhaohai point (Zhaohai is where Yang adds to Yin, the root of erection), then ascends along the inner ankle, with Jiao Xin as the Xi point (Jiao Xin is the connection of the union), passing through the Tai Yin Di Ji (this segment is my addition), directly upward along the Yin thigh (Ji Mai is also known as the rising meridian, which cannot be blocked), entering Yin (Hui Yin, excitement causes the Yin organ to rise).
Thus, the segment Jiao Xin – Di Ji – Ji Mai is the Yin Qiao Meridian, connecting Tai Yin, Shao Yin, and Jue Yin, unblocking the fire of the heart and the fire of life.
Sexual intercourse mainly involves the activity of the Jue Yin Liver Meridian, but it releases the essence of the Shao Yin Kidney and the Qi of the Tai Yin Spleen. Therefore, the Suwen states: “When the Kidney Qi is abundant at the age of sixteen, the heavenly essence arrives, the essence overflows, Yin and Yang harmonize, thus one can conceive.”
I have long contemplated the addition of Di Ji to the Yin Qiao. Clinically, using Di Ji to treat urogenital system diseases has been enlightening.
Section Nine: Foot Meridians
1. Foot Three Yang Meridians
The area innervated by the lateral nerves of the foot corresponds to the toes and is related to the Liver and Gallbladder (Shao Yang), while the heel end is related to the Colon (Yang Ming). The Tai Yang Meridian runs along the lateral side of the foot’s dorsal surface.
The Carpal Bone and Jing Bone are the original points for the Hand and Foot Tai Yang, located opposite each other. One treats Tai Yang and Shao Yang diseases causing jaundice, while the other treats Tai Yang and Jue Yin diseases causing convulsions and seizures.
The Jing Bone’s lower position corresponds to the liver and gallbladder reflex area on the foot’s sole, similar to the Carpal Bone, but since the Jing Bone is deeper in the foot, it is more often used for Jue Yin diseases.
To treat liver and gallbladder diseases, one should needle the right Jing Bone (on the same side as the liver), inserting horizontally while simultaneously stimulating the liver and gallbladder area on the foot’s sole, which is located beneath the Shao Yang Gallbladder Meridian on the foot’s dorsal surface.
The sole corresponds to the dorsal position of the foot, with Nei Xia Xi and Nei Lin Qi respectively.

The medial sural cutaneous nerve runs deep within the soleus fascia, between the two heads of the gastrocnemius muscle.
It emerges from the fascia around the midpoint of the calf, receiving a communicating branch from the fibular nerve, and is called the gastrocnemius nerve.
The gastrocnemius nerve descends along the lateral edge of the Achilles tendon, turning forward between the lateral malleolus and the calcaneus, known as the lateral dorsal cutaneous nerve, distributing along the foot and the outer edge of the little toe, which is the pathway of the Foot Tai Yang Meridian.
2. Foot Three Yin Meridians
The sole is innervated by the medial plantar nerve from the tibial nerve, with the lateral side of the toes related to the Tai Yin Spleen (the lateral side is the pathway of the Foot Tai Yin Meridian).
The medial side of the toes is related to the Tai Yin Lung, while the heel end corresponds to the reflex area of the Shao Yin Kidney, with the junction being the Yong Quan point (the starting point of the Foot Shao Yin Kidney Meridian).
The fibular nerve’s medial branch is related to the Kidney (external kidney). The saphenous nerve’s innervation area ends at the Ren Gu point.
The Foot Jue Yin Liver Meridian does not run along the sole. The common fibular nerve wraps around the neck of the fibula, entering the gastrocnemius muscle, and divides into the superficial and deep fibular nerves beneath the Yang Ling Quan point.
The superficial fibular nerve:
One branch descends to the front of the lateral malleolus (running along the pathway of the Foot Shao Yang Meridian), and the other runs behind the lateral malleolus (running along the pathway of the Foot Bladder Meridian).
The deep fibular nerve emerges shallowly between the first and second toes, innervating this area (the Foot Jue Yin Liver Meridian’s Da Dun / Du Yin – Xing Jian – Tai Chong).
Thus, the Yang Ling Quan point effectively connects the Tai Yang, Shao Yang, and Jue Yin Meridians.
Generally, the Yong Quan corresponds to the Ming Men, and the Di Gen corresponds to the Tian Gen. The Yong Quan to Di Gen corresponds to the Ren Meridian’s Shen Que to Qu Gu.
