The yin-qiao pathway begins below the medial malleolus at KI-6 (zhao hai), moves up the medial aspect of the thigh, crosses the perineum, passes laterally to the umbilicus, runs to the chest, and comes to the supraclavicular fossa. Then, the path moves up laterally to the throat and ascends in front of ST-9 (ren ying). From here, it crosses the medial aspect of the cheek and reaches the inner canthus, where it connects with the yang-qiao (yang heel/motility channel) and bladder channel at UB-1 (jing ming). It then moves up over the head and into the brain.
