绣按∶十二经络，皆为人身通气活血之具。其脉周流岐别，不可不为辨论，以究病情之起端，邪气之胜复，
气血之盈亏，则临症索病，自有其枢，而不为其所惑矣，此经络歌义之不容忽也。玩书有言，直行为经，
旁行为络。一似经络之义，业已尽是。讵知人身经络，其理推究靡穷，
有可分论而见其端者，有可合论而得其意者。其分论而见，盖以经起中焦，常随营气下行而上。络起下焦，恒
附营气上行而下。经起中焦，则经气之上升，实有过于其络。络起下焦，则络气之下降，实有越于其经。
故经多以气主，而络多以血主也。经主于气，故凡外邪之入，多于经受，而络常处于后；络主于血，故凡经邪
之满，转溢于络，而络始得以受。是以经常处实，络常处虚。络得由经而实，而络亦不得以虚名也。经因受
邪最早，故症多以寒见，而脉亦寸浮而紧；络因受邪稍缓，故症多因热成，而脉常见尺数而涩。经则随行上下，
邪本易受，而开发最易；络则邪伏隐僻，邪即难入，而升散维艰。即经有言络处经外，邪入先自络始；然既
由络入经，而经流连不散，则邪又溢于络，而见缠绵不已，故经与络又各自病。是其各别之势，有不相混如
此。以经络通同而论，则经与络，虽各本于脏气之受，然究不越人身大气以为鼓运，故能流行不悖。设非大气
磅因礴，则彼盛此衰，生气有阻，其何以为长养元气之自乎。此其会通之妙，又有不容或忽如此。是以初病多责
于经，久病多责于络。久病而再流连不解，则又多责于经之奇。以故仲景着为伤寒论法，多以经传立
解。孙思邈着为千金等书，多以络病久病立说。即今姑苏叶天士，祖孙思邈，作为临症指南集，亦以久病活络
为要，皆与经络不悖。第其经穴众多，其中错综分行，自非纂诵，难以记忆。因阅汪昂本草备要所订古
本歌诀，颇有便世，用是附载以为采择，非惟初学得此，可以诵习；即老医得此，亦可以为临症之一助也。

Wang Ang's Commentary: The twelve meridians are the channels through which Qi circulates and Blood moves in the human body. Their pulse qi flows circumferentially with numerous branches, requiring careful differentiation and discussion to investigate the onset of diseases, the fluctuation of pathogenic factors, and the deficiency or excess of Qi and Blood. This allows one to grasp the key when seeking the cause of disease during clinical practice, avoiding confusion by superficial manifestations. This is why the significance of the meridian songs cannot be ignored. Readers say that straight-running vessels are Jing (Meridians), and branching vessels are Luo (Collaterals). It seems as if the meaning of Jing and Luo has been fully explained. However, the principles of the body's Jing and Luo are infinitely profound upon investigation. Some aspects can be analyzed separately to see their beginnings, while others can be discussed collectively to grasp their essence. The separate analysis reveals that Jing originates from the Middle Jiao and usually descends while carrying Ying (Nutrient) Qi upward; Luo originates from the Lower Jiao and usually ascends while attaching to Ying (Nutrient) Qi downward. Since Jing originates from the Middle Jiao, the ascending of Jing Qi actually exceeds that of Luo Qi. Since Luo originates from the Lower Jiao, the descending of Luo Qi actually surpasses that of Jing Qi. Therefore, Jing is primarily governed by Qi, while Luo is primarily governed by Blood. Because Jing governs Qi, external pathogens mostly invade the Jing first, leaving the Luo in a secondary position; because Luo governs Blood, when Jing pathogens become full, they overflow into the Luo, allowing the Luo to receive them. Thus, Jing often exists in a state of Excess, while Luo often exists in a state of Deficiency. When Luo becomes solid through Jing, it can no longer be considered deficient. Since Jing receives pathogens earliest, symptoms often manifest as Cold, with pulses being Floating and Tight at the Cun position; since Luo receives pathogens more slowly, symptoms often arise from Heat, with pulses commonly being Rapid and Choppy at the Chi position. Jing travels up and down with the body, making it easy for pathogens to enter and easy to disperse; Luo harbors pathogens in hidden and remote places, making entry difficult and dispersion arduous. Although texts state that Luo is outside Jing and pathogens enter via Luo first, once pathogens enter Jing and linger without dispersing, they overflow back into Luo, resulting in lingering symptoms. Thus, Jing and Luo can each suffer independently. Their distinct tendencies are so different that they do not mix. Discussing Jing and Luo as interconnected, although both originate from Zang organ Qi reception, they ultimately rely on the Great Qi of the body for propulsion, ensuring smooth circulation without deviation. Without this majestic Great Qi, imbalance would occur, obstructing Sheng (Vital) Qi, undermining the nourishment of Yuan (Original) Qi. This妙 (wonder) of integration is also不容忽视 (cannot be ignored). Therefore, early-stage diseases are often attributed to Jing, while chronic diseases are attributed to Luo. If chronic diseases linger unresolved, they are often attributed to the Qi Jing (Extraordinary Vessels). Hence, Zhang Zhongjing's *Shanghan Lun* (Treatise on Cold Damage) largely explains pathology based on Jing transmission. Sun Simiao's *Qianjin Fang* (Thousand Golden Prescriptions) focuses on Luo diseases and chronic conditions. Ye Tianshi of Suzhou, following Sun Simiao, wrote *Linzheng Zhinan* (Clinical Guide), emphasizing activating Luo for chronic diseases, all consistent with meridian theory. However, the acupoints are numerous and intricately distributed; without compiled songs for recitation, memorization is difficult. Having read Wang Ang's ancient song verses in *Bencao Beiyao* (Essentials of Materia Medica), which are convenient for the world, I attach them here for selection. Not only can beginners learn and recite them, but even experienced physicians can use them as an aid in clinical practice.
Hand-Taiyin Lung Meridian: The Hand-Taiyin Lung meridian originates in the Middle Jiao, descends to connect with the Large Intestine (Lung and Large Intestine are exterior-interior pairs), passes through the upper epigastrium (cardia), ascends through the diaphragm, and belongs to the Lung. From the Lung system (trachea/larynx), it emerges horizontally from under the axilla, curves inward along the arm (the area below the shoulder opposite the axilla, pronounced 'rou'), runs anterior to the Heart and Pericardium meridians, descends along the medial aspect of the elbow, follows the upper border of the forearm bone, enters the Cun Kou (pulse point anterior to the wrist crease), ascends to the Yu Ji (fleshy eminence at the base of the thumb), and terminates at the radial side of the nail bed of the thumb (Shaoshang point). A branch emerges from behind the wrist, connects to the radial side of the index finger, and intersects with the Yangming Large Intestine meridian. This meridian has abundant Qi and little Blood. Pathological changes manifest as wheezing, chest fullness, and coughing (Lung governs Qi). Pulmonary distension, pain in Quepen (depression below the clavicle, a Stomach meridian point), crossing of hands causing numbness (pronounced 'mao') known as Arm Jue, are indicative. Diseases generated by the Lung include cough, rebellious Qi, asthma, thirst, heart vexation, and chest fullness/stagnation (meridians distribute in the chest). Pain along the anteromedial aspect of the arm, either cold/numbness or heat in the palm (Laogong point belongs to Pericardium), indicates involvement. Shoulder and back pain signifies excess Qi (collaterals intersect hands and ascend to shoulder/back); frequent urination with short volume or sweating indicates Lung governing skin/hair. Qi deficiency causes pain (cold pain in shoulder/back), changes in urine color (Mother affecting Child), and shortness of breath insufficient to complete inhalation (Lung deficiency).

Symptoms include chills, groaning, yawning, and dark complexion. Patients fear fire and people, dislike wood sounds, feel palpitations, desire solitude, and in severe cases, climb high or run naked. Abdominal rumbling and distension lead to leg Jue. Mania, malaria, warm diseases, and sweating occur. Rhinorrhea, epistaxis, lip ulcers, neck swelling, throat obstruction, and abdominal edema are possible. Pain occurs at Yingchuan, Ruzhong, Rugen, kneecap, Futu, lateral calf, and dorsum of the foot. Excess Qi causes heat in the anterior body, excessive hunger, and dark urine. Deficiency causes cold in the anterior body, gastric cold, and abdominal distension.
