手太阴肺中焦生，络肠循胃散流行，上膈属肺从肺系，横出腋下臑肘中，
循臂寸口上鱼际，大指内侧爪端通，支络还从腕后出，接次指属阳明经。
注：[1]手太阴肺经之脉，起于中焦者，言起于任脉中脘穴也。
[2]下络大肠，还循胃口者，谓本经之络，散布流行，下则络于大肠，
还上而循胃口，非上膈属肺直行之经也。
[3]夫经络流行，循还无端。故手太阴之脉，必自足厥阴经之支者期门穴，
循行中脘穴，上膈属肺，以交于手太阴肺经也。
[4]从肺系横出腋下，至于中府、云门穴，下循臑内天府、侠白穴；
从侠白行少阴心主经脉之前，下行肘中尺泽穴；
从尺泽循臂内上骨下廉孔最穴，从孔最入寸口列缺、经渠、太渊穴；
从太渊上鱼（句）入鱼际穴；从鱼际出大指之端少商穴而终焉。
[5]其支者从腕后直出，循行次指内廉出其端，以交于手阳明大肠经也。

The Lung Meridian of Hand-Taiyin originates in the Middle Jiao (Middle Burner), descends to connect with the Large Intestine, returns to follow the stomach opening, ascends through the diaphragm and belongs to the Lung. From the lung system (trachea, larynx, and associated tissues), it emerges horizontally from the armpit,
descends along the medial aspect of the upper arm, running anterior to the Heart Meridian of Hand-Shaoyin and Pericardium Meridian of Hand-Jueyin, descends into the cubital fossa, follows the medial border of the forearm bone, enters the Cun Kou (radial pulse point), ascends to the Thenar eminence,
follows the margin of the thenar eminence, and exits at the tip of the thumb; its branch arises from behind the wrist, goes straight to the medial border of the index finger, and reaches its end (Figure 39).
Text:
The Qi of the Hand-Taiyin Lung Meridian is generated in the Middle Jiao, connects with the intestines, circulates along the stomach, and spreads diffusely. It ascends through the diaphragm, belongs to the Lung, emerges horizontally from the lung system, passes through the axilla, upper arm, and elbow,
continues along the forearm to the Cun Kou and the thenar eminence, communicates at the lateral side of the nail root of the thumb. The branch diverges from behind the wrist, travels to the medial side of the index finger, and connects with the Yangming Meridian.
Note: [1] The meridian of the Hand-Taiyin Lung Meridian originating in the Middle Jiao refers to its starting point at the Zhongwan (CV12) acupoint on the Ren Mai (Conception Vessel).
[2] "Descends to connect with the Large Intestine, returns to follow the stomach opening" means that the collateral vessels of this meridian spread and circulate; downward they connect with the Large Intestine,
and upward they follow the stomach opening. This does not refer to the main meridian ascending through the diaphragm to directly belong to the Lung.
[3] Since the flow of meridians and collaterals is continuous and cyclical without beginning or end, the meridian of Hand-Taiyin must necessarily originate from the branch of the Foot-Jueyin Liver Meridian at the Qimen (LR14) acupoint,
travel to the Zhongwan (CV12) acupoint, ascend through the diaphragm to belong to the Lung, thereby connecting with the Hand-Taiyin Lung Meridian.
[4] Emerging horizontally from the lung system into the axilla, it reaches the Zhongfu (LU1) and Yunmen (LU2) acupoints, descending along the medial aspect of the upper arm to the Tianfu (LU3) and Xiabai (LU4) acupoints;
from Xiabai, it runs anterior to the Heart Meridian of Hand-Shaoyin and Pericardium Meridian of Hand-Jueyin, descending to the Chize (LU5) acupoint in the cubital fossa;
from Chize, following the medial border of the forearm bone, it reaches the Kongzui (LU6) acupoint, entering the Cun Kou region at the Lieque (LU7), Jingqu (LU8), and Taiyuan (LU9) acupoints;
from Taiyuan, it ascends to the Thenar eminence (pause) and enters the Yuji (LU10) acupoint; from Yuji, it exits at the Shaoshang (LU11) acupoint at the tip of the thumb, where it terminates.
[5] Its branch arises straight from behind the wrist, follows the medial border of the index finger to its tip, thereby connecting with the Hand-Yangming Large Intestine Meridian.
