Point name meaning:
This point marks the advance of the kidney channel up to the rib cage. The character 步 (bù), meaning to step,
can be seen as a reference to the channel stepping up into the chest, or could be a reference to the nature of the channel in the region of the chest. The points proceed stepwise up the rib cage, one rib at a time. The ideograph 廊 (láng) can mean either a path upward (toward a summit)
or a corridor.
The former interpretation simply describes the path of the kidney channel. As regards the latter interpretation, the left and right kidney channels, when charted on the chest, resemble a corridor.
Two translations of this name become possible in this light. Corridor Walk encompasses the idea of a corridor and the rib-by-rib, step-by-step nature of the channel, while Step Upward would include the idea of the channel advancing into the region of the chest and the notion of an upward path. See
