At a glance
The pairing by which the six channels are organised into three couples: greater yang with lesser yin, lesser yang with ceasing yin, yang brightness with greater yin. Chapter 24 gives the pairing for the foot and then for the hand, and the hand list is the interesting one — where the foot says ceasing yin, the hand says the heart master, which is how the text names the pericardium when it needs to keep it distinct from the foot channel of the same name. Note that exterior and interior here are a relation between channels, not the depth of a disease; the chapter’s own use is anatomy, not diagnosis.
Passages where the term does real work, with the original, pinyin and English on the same line.
Every rendering below is a decision about which reader is being addressed. There is no neutral option.
| Wiseman & Feng | exterior/interior | They keep the pair as a fixed technical dyad, which is how the term functions in later literature. |
| Unschuld | the outer and the inner | He drops the garment and states the relation directly, at the cost of the picture. |
| This site | exterior and interior | The graphs are a coat and its lining, and the medical sense is still spatial — one channel on the outer face of the limb, one on the inner. Keeping the garment word keeps that in view. |
