The Lung Meridian of Hand-Taiyin (Hand-Taiyin Lung Meridian). It originates at Zhongfu (LU-1), emerges from the axilla, runs along the medial aspect of the arm, passes through Cun Kou (Radial Pulse), reaches Yu Ji (LU-10), exits at the tip of the thumb, and terminates at Shao Shang (LU-11). There are eleven acupoints in this meridian; six are recorded here.

Zhongfu (LU-1) (also known as Yingzhongshu): Located one cun below Yunmen (LU-2), six cun lateral to the anterior midline (Ren Mai) at Huagai (DU-16). It is situated in the depression between the third intercostal space above the nipple, where arterial pulsation can be felt. The patient should assume a supine position for needling.

This point is an intersection of the Hand-Taiyin and Foot-Taiyin meridians. Needle depth: 0.3 cun; retain needle for five breaths. Moxibustion: three moxa cones. Indications: acute lung qi stagnation with chest fullness, turbid nasal discharge, throat obstruction (Hou Bi), rebellious qi with frequent swallowing difficulties, inability to eat, facial edema due to Wind-Lung, and alternating cold and heat involving the Lung and Gallbladder. This point primarily drains heat from the chest; its therapeutic actions are similar to those of Quepen (LI-15) and Fengfu (DU-16).

Yunmen (LU-2): Located 1.6 cun directly above Zhongfu (LU-1) in the depression, where arterial pulsation can be felt. Raise the arm to locate the point. Needle depth: 0.3 cun. Moxibustion: five moxa cones. *Jia Yi Jing* states that excessive needle depth may cause dyspnea. *Qian Jin Fang* suggests moxibustion up to fifty cones. Indications: sore throat, laryngeal closure, goiter, persistent limb fever due to Cold Damage (Shang Han), cough with rebellious qi, shortness of breath, and qi rushing upward to the heart and chest.

Tianfu (LU-3): Located on the medial aspect of the arm, three cun below the axilla, in the depression of the arterial pulse. To locate, mark the spot with ink using the tip of the nose. Needle depth: 0.3 cun; retain needle for three breaths. Moxibustion is contraindicated, as it may cause rebellious qi. Indications: sudden bi-syndrome, internal qi rebellion, binding of Liver and Lung qi, hematemesis and epistaxis, Feishi Guizhu (ancient term for sudden, severe infectious diseases). *Bai Zheng Fu* states that combined with Hegu (LI-4), it can stop epistaxis.

Chize (LU-5): Located in the center of the elbow, above the transverse crease. With the elbow flexed, it is found in the gap between the tendons and bones at the crease, where arterial pulsation is present.

The Lung Meridian enters and converges here, forming the He-Sea point. For excess patterns of the Lung, tonification or sedation should be applied appropriately (here implying sedation for excess). Needle depth: 0.3 cun; retain needle for three breaths. Moxibustion: three moxa cones. Zhen Quan stated that in the gap between tendons and bones at the transverse crease during arm flexion/extension, moxibustion is not suitable. Indications: vomiting, rebellious qi, throat obstruction, abdominal pain, vexation, dry tongue, and slow convulsions in children (one moxa cone). *Qian Jin Yi Fang* states that heaviness and pain in the four limbs due to pathogenic factors, and various miscellaneous conditions, are governed by Chize. Also known as Guitang. Another saying goes: "For five types of elbow pain, seek Chize."

Yuji (LU-10): Located in the depression on the medial side of the thenar eminence, behind the metacarpophalangeal joint, among the scattered vessels, at the junction of white skin.

The Qi of the Hand-Taiyin flows and gathers here, forming the Ying-Spring point. Needle depth: 0.2 cun; retain needle for three breaths. Moxibustion: three moxa cones. Indications: dry throat, mastitis, yellow coating on the tongue, fever with aversion to cold, and wine-induced disorders. *Bai Zheng Fu* states that combined with Yexin (EX-HN18, though text says Yeximen/Yemen contextually likely referring to local or specific pairing, literal translation 'Yexian' might be typo for Yexin or similar, keeping literal 'Yexian' as per source structure but noting standard texts often cite Hegu/Liuequan etc. Here strictly translating source 'Yexian'): it treats sore throat. If transmitted to toothache with inability to eat, treat the affected side (left for left, right for right). Men: three moxa cones; Women: four moxa cones.

Shaoshang (LU-11): Located at the medial tip of the thumb, approximately the width of a leek leaf from the corner of the nail, in the depression of the white skin. The Qi of the Hand-Taiyin emerges here, forming the Jing-Well point. Needle depth: 0.1 cun; retain needle for three breaths and five inhalations. Use a three-edged needle to prick slightly for bleeding to drain heat from the zang-fu organs. Moxibustion is contraindicated. Indications: neck swelling, throat obstruction, vexation, vomiting and hiccups, night blindness (Que Mu), dry lips with excessive saliva, inability to eat, pain in the wrist and fingers, and infantile tonsillitis (Ru E). *Qiankun Shengyi* states: This is one of the Ten Jing-Well points. In cases of sudden stroke within the state, coma, phlegm-rheum congestion, locked jaw, and inability to swallow water or grain, urgently prick this point with a three-edged needle, along with Shaochong (HT-9), Zhongchong (PC-9), Guanchong (SJ-1), Shaoze (SI-1), and Shangyang (LI-1), to promote the flow of Qi and Blood. This is a miraculous emergency point for reviving the dying.
