The Lung Meridian of Hand-Taiyin originates at Zhongfu (LU-1), located approximately one cun below Yunmen (LU-2); Yunmen is situated six cun lateral to the midline, below Jugu (SI-1). Tianfu (LU-3) is sought three cun below the axilla; Xiabai (LU-4) governs conditions when located five cun above the elbow; Chize (LU-5) is discussed at the center of the cubital crease; Kongzui (LU-6) is taken seven cun above the wrist crease; Lieque (LU-7) is one and a half cun above the wrist crease; Jingqu (LU-8) is found in the depression at the radial pulse (Cunkou); Taiyuan (LU-9) is at the head of the transverse crease of the wrist; Yuji (LU-10) is elevated where the dispersed vessels scatter after the thenar eminence; Shaoshang (LU-11) is on the medial end of the thumb. Needling this point stops epistaxis immediately. (Note: Yunmen is in the depression two cun lateral to Xiayuhu, below Jugu, six cun from the anterior midline Ren Meridian. Qihu is in the depression two cun lateral to Yufu, below Jugu, four cun from the anterior midline and 4.8 cun from Yingchuang. Yufu is in the depression two cun lateral to Xuanji, below Jugu. Xuanji is one cun below Tiantu. Tiantu is in the depression four cun below the laryngeal prominence. The method for locating points on the right side starts from Tiantu to Xuanji, then to Yunmen; this method is very simple, and subsequent points follow this pattern.)

The Hand-Taiyin Lung Meridian begins at the tip of the index finger, follows the radial border of the finger, emerges between the two bones at Hegu (LI-4), enters between the two tendons, follows the radial border of the forearm, enters the lateral aspect of the elbow, ascends along the anterolateral aspect of the upper arm, reaches the shoulder, emerges anterior to the bone, reaches the intersection of the Zhu Gu (Dazhui GV-14), descends into Quepen (ST-12), connects with the Lung, passes through the diaphragm, and belongs to the Large Intestine. Its branch rises from Quepen to the neck, penetrates the cheek, enters the lower teeth, returns to encircle the mouth, crosses at Renzhong (GV-26), with the left meridian crossing to the right and the right to the left, ascending to flank both sides of the nostrils. When the Qi of this meridian moves abnormally, it causes toothache and neck swelling. This meridian primarily governs diseases related to fluid metabolism, presenting as yellow eyes, dry mouth, rhinorrhea or epistaxis, pharyngitis, pain in the anterior shoulder, and pain or dysfunction of the thumb and index finger. Excess Qi results in heat and swelling along the meridian's pathway; deficiency results in chills that do not resolve, leading to these various ailments. ("" pronounced 'yu kou', "cheek" pronounced 'jiu yue', "rhinorrhea" sounds like 'qiu', "epistaxis" sounds like 'niu').

This passage describes the circulation of Qi in the Large Intestine Meridian, which is the second meridian. "The tip of the index finger next to the thumb" refers to the second finger of the hand, namely the index finger. The Lung Meridian originally originates from the thumb, while the Large Intestine Meridian originates from the index finger; thus, "the tip of the index finger next to the thumb" refers to the finger adjacent to the thumb, not implying origin from both the thumb and the index finger. Hegu is an acupoint of this meridian (commonly known as the tiger's mouth). The space between the two bones at the shoulder end is called the bone. The upper edge of the scapula is called the Heavenly Pillar Bone. Quepen is an acupoint of the Foot-Yangming Stomach Meridian. The stem of the head is the neck; the curved area below the ear is the cheek. The text mentions the Large Intestine, referring to the Hand-Yangming Large Intestine Meridian, which receives the connection from the Hand-Taiyin Lung Meridian, thus originating at the tip of the finger, following the radial border of Shangyang (LI-1), Erjian (LI-2), Sanjian (LI-3), emerging at Hegu between the two bones, ascending again to Yangxi (LI-5) between the two tendons, then following the radial border of the forearm through Pianli (LI-6), Wenliu (LI-7), Xialian (LI-8), Shanglian (LI-9), Sanli (LI-10), entering Quchi (LI-11) at the lateral elbow, ascending along the anterolateral aspect of the upper arm through Wuli (LI-13) and Binao (LI-14), reaching the shoulder Shangu (LI-15), emerging anterior to the bone, following Jugu (SI-1), ascending to the intersection of the Heavenly Pillar Bone (Dazhui GV-14), meeting at Dazhui, descending from Dazhui into Quepen, following the Foot-Yangming Stomach Meridian, laterally connecting and surrounding the Lung, descending through the diaphragm, meeting and belonging to the Large Intestine outside Tianshu (ST-25); its branch, although entering from Pianli, also ascends from Quepen to the neck, following Tianding (LI-16) and Futu (LI-18), penetrating the cheek, entering the lower gum, returning to flank the corners of the mouth (Dicang ST-4), intersecting inside Renzhong (GV-26), with the left meridian going to the right and the right to the left, ascending to flank the nostrils, following Heliao (LI-19) and Yingxiang (LI-20) to terminate, thereby connecting with the Foot-Yangming Stomach Meridian. Diseases of this meridian manifest as yellow eyes, nasal congestion, and other symptoms.
