The meridian of Foot-Shaoyang (Gallbladder) originates at the outer canthus (Shaozhuang, GB1), ascends to the head corner, then descends behind the ear, follows the neck, running anterior to the meridian of Hand-Shaoyang (Sanjiao); upon reaching the shoulder, it crosses posteriorly, running behind the meridian of Hand-Shaoyang (Sanjiao), and enters the Clavicular Fossa (Quepen, SI15).

A branch from the ear enters the auditory canal, emerges anterior to the ear, reaches the outer canthus, descends to meet the Large Ying point (Daying, ST9), connects with the meridian of Hand-Shaoyang (Sanjiao), descends to the Jawbone point (Jiache, ST6), then goes down the neck to converge with the clavicular fossa meridian. From there, it descends into the chest, penetrates the diaphragm, links with the Liver, belongs to the Gallbladder, runs along the interior of the costal margin, emerges at the Qichong point (Qichong, ST30), surrounds the pubic region, and transversely enters the Hip Crevice (Huantiao, GB30).

The straight branch descends from the Clavicular Fossa to the axilla, passes along the lateral chest through the Hypochondrium (the end of the ribs is called the hypochondrium), converges downward with the Hip Crevice (referring to the junction of the lower abdomen and upper thigh), and continues down the lateral aspect of the thigh, emerging at the lateral knee (Yanglingquan, GB34). It descends anterior to the fibula (the fibula is the smaller bone assisting support, located lateral to the tibia), reaches the end of the Juegu (Yangfu, GB38), emerges anterior to the lateral malleolus (Qiuxu, GB40), follows the dorsum of the foot, and emerges at the tip between the little toe and the second toe (Xiaxi, GB43 is anterior to the metatarsophalangeal joint, Zulinqi, GB41 is posterior to it, and Guixin, GB44 is further distally).

Another branch arises from the dorsum of the foot, enters between the bones of the big toe, emerges at its tip, extends distally through the nail bed, and emerges at the hair tuft (here it intersects with the Foot-Jueyin Liver meridian).

When the meridian is affected by pathogenic factors, symptoms include bitter taste in the mouth, frequent sighing, pain in the heart and hypochondrium, inability to turn the body; in severe cases, the face appears dusty and dull, the body lacks luster, and heat occurs on the lateral aspect of the foot, known as "Yang Jue" (Yang Reversal).

This meridian primarily governs diseases of the bones, including: headache, temporal pain, pain at the outer canthus, swelling and pain in the middle of the Clavicular Fossa, axillary swelling, "Ma Dao" sores (scrofula-like lesions), "Jia Ying" (goiter-like swelling), sweating, chills, malaria, pain in the chest, hypochondrium, ribs, thigh, lateral knee, lower leg, Juegu, anterior lateral malleolus, and all joints; dysfunction of the little toe and second toe. In cases of excess, the Renying pulse (carotid artery) is one times larger than the Cunkou pulse (radial artery); in cases of deficiency, the Renying pulse is smaller than the Cunkou pulse.
