The Pericardium Meridian has nine acupoints: Tianchi (PC1) is located proximally; Tianquan (PC2), Quze (PC3), and Ximen (PC4) require careful identification; Jianshi (PC5) and Neiguan (PC6) are distal to the wrist; Daling (PC7), Laogong (PC8), and Zhongchong (PC9) are located on the palm and the tip of the middle finger.

The Hand-Jueyin Pericardium Meridian originates from Tianchi (PC1). This point is located one cun lateral to the nipple, three cun below the axilla. Tianquan (PC2) is found two cun below the axilla, encircling it. Quze (PC3) is located in the depression at the midpoint of the transverse cubital crease when the elbow is flexed. Ximen (PC4) is five cun proximal to the transverse wrist crease. Jianshi (PC5) is three cun proximal to the transverse wrist crease. Neiguan (PC6) is two cun proximal to the transverse wrist crease. Daling (PC7) is located between the transverse creases of the wrist. Laogong (PC8) is located in the center of the palm, accessible by curling the fingers (specifically between the second and third metacarpal bones). Zhongchong (PC9) is located at the tip of the middle finger.

[Note] Tianchi (PC1) is approximately one to two cun lateral to the nipple, directly three cun below the axilla, situated in the intercostal space of the prominent ribs in the hypochondriac region. From Tianchi (PC1), moving obliquely upward, around the axilla, and descending along the medial aspect of the arm for two cun, with the arm raised, one can locate Tianquan (PC2). Descending from Tianquan (PC2), on the medial side of the large tendon in the inner elbow, in the depression below the head of the transverse crease where arterial pulsation is felt, lies Quze (PC3). Descending from Quze (PC3), five cun proximal to the transverse wrist crease, is Ximen (PC4). Descending from Ximen (PC4), three cun proximal to the transverse wrist crease, in the depression between the two tendons, is Jianshi (PC5). Descending from Jianshi (PC5), two cun proximal to the transverse wrist crease, between the two tendons, is Neiguan (PC6). Descending from Neiguan (PC6), in the depression between the two tendons within the transverse crease under the bone of the wrist, is Daling (PC7). Descending from Daling (PC7), at the arterial pulse in the center of the palm, accessible by flexing the ring finger, is Laogong (PC8). Descending from Laogong (PC8), at the tip of the middle finger, in the depression approximately the width of a leek leaf from the corner of the nail, is Zhongchong (PC9).

The Classic states: The Kidney is the official of strength and vigor, from which skill and dexterity emerge. It also states: The Kidneys are attached below the fourteenth vertebra of the spine. [Note: The original text claims this meridian is "abundant in blood and deficient in qi," which is anatomically/meridian theory incorrect for the Pericardium or Kidney meridians, but translated as per source]. Its association is with the bones, its luster manifests in the hair, and it opens into the two orifices (anterior and posterior).

The Nan Jing states: There are two kidneys, weighing one jin and two liang, whose primary function is to store essence and will (Zhi).

The Zhong Zang Jing states: The Kidney is the residence of spirit and mind, and the root of life and nature.

Zhang Jiebin stated: There are two kidneys, shaped like kidney beans. They lie side by side and curved, attached to both sides of the spine, each one and half cun away from the spine; they are wrapped externally by yellow fat, and each has two ligaments. The upper ligament connects to the Heart, and the lower ligament trends toward the great bone below the spine, at the end of the spinal column, approximately half a hand's length away; there are two acupoints in the middle, which are the passages of the renal ligaments, ascending through the spinal cord to the brain, connecting to the Sea of Marrow.
