The Hand-Yangming Meridian originates at Shangyang (LI1), followed by Erjian (LI2), Sanjian (LI3), and Hegu (LI4). Yangxi (LI5), Pianli (LI6), and Wenliu (LI7) are located sequentially, with Xialian (LI8), Shanglian (LI9), and Sanli (LI10) extending along the arm. Quchi (LI11), Zhouliao (LI12), Yingxiang (LI20), Wuli (LI13), Binao (LI14), Jianyu (LI15), and Jugu (LI16) are situated around the elbow and shoulder. Tianding (LI17), Futu (LI18), He liao (LI19), and Yingxiang (LI20) connect in sequence, totaling twenty acupoints on this meridian.

The Hand-Yangming Meridian belongs to the Large Intestine, originating at Shangyang (LI1) on the radial side of the index finger. Erjian (LI2) is located proximal to the first metacarpophalangeal joint, while Sanjian (LI3) is distal to it. Hegu (LI4) is found in the depression between the first and second metacarpal bones. Yangxi (LI5) is detailed in the dorsal-radial depression of the wrist. Pianli (LI6) is one cun distal to the wrist crease, and Wenliu (LI7) is five cun away. Xialian (LI8) and Shanglian (LI9) are each one cun apart; Sanli (LI10) is located one cun below Shanglian (LI9). When the elbow is flexed, Quchi (LI11) is obtained at the end of the transverse cubital crease. Sanli (LI10) is two cun below Quchi (LI11). Zhouliao (LI12) is in the depression lateral to the large bone of the elbow, and Wuli (LI13) is measured three cun above the elbow. Binao (LI14) is taken one cun below the upper arm region, and Jianyu (LI15) is at the shoulder tip between the two bones. Jugu (LI16) is medial to the clavicle's acromial process. Tianding (LI17) is needled above the Quepen (ST12) area. Futu (LI18) is one cun below the angle of the mandible, and Heliao (LI19) is five fen lateral to Shuigou (GV26). Yingxiang (LI20) is located five fen lateral to both sides of the nostrils, on the left and right.

Stomach Organ Shape Diagram
The Classic states: The Stomach is the official responsible for storage and processing, from which the Five Flavors emerge. It is also referred to as the "Yellow Intestine."
When flavors enter the mouth, they are stored in the Stomach to nourish the Qi of the Five Zang Organs. The Stomach is the sea of water and grain, and the great source of the Six Fu Organs; thus, the essence and qi of all Zang and Fu organs originate from the Stomach.
Food entering the Stomach disperses its essence to the Liver, enriching the sinews. Food entering the Stomach sends its turbid qi to the Heart, enriching the vessels. The qi flowing through the vessels reaches the meridians, and the meridian qi converges in the Lungs.
The Lungs govern all vessels, distributing essence to the skin and hair. The essence of the skin and hair combines, moving qi through the Fu organs. The Fu organs' spirit and brightness remain in the Four Zang Organs, and the qi returns to a state of balance. When balanced, the Cun pulse forms at the Radial Artery, allowing for the determination of life and death.
Water entering the Stomach allows its essence to overflow upward to the Spleen. The Spleen scatters the essence upward to the Lungs, which regulate the water passages and transport it downward to the Bladder. Water essence distributes throughout the body, running parallel through the Five Channels. This conforms to the Yin-Yang of the Four Seasons and Five Zang Organs, serving as the standard for measurement.
Normally, the human Stomach retains two dou of grain and one dou and five sheng of water. Therefore, a healthy person defecates five times daily, expelling five sheng, totaling three dou and five sheng over seven days. Thus, a healthy person will die after seven days without food.
