Each entry gives the term in traditional and simplified form, its pinyin, the senses it carries in the classical corpus, the passages where it does real work, and how published translations have rendered it.
dàn zhōng
The fifth office, and the one whose name readers meet twice: as the office from which joy issues, and as the acupuncture point between the breasts. 膻中者，臣使之官，喜樂出焉 — the chest centre is the envoy, the one who carries the ruler's commands outward, which is why what issues from it is 喜樂 and not judgement. Later tradition identifies it with the pericardium (心包絡), the wrapping that takes the blow on the heart's behalf.
xuán fǔ
The dark openings — 玄 xuán, what is dim and cannot be made out; 府 fǔ, a chamber where things are stored — and the chapter gives its own gloss for them: 所謂𤣥府者，汗空也, the dark openings are the sweat pores, 空 read kǒng after 王冰: 空，孔也. That reading is worth holding against 骨空 in chapter 60, one chapter back, where the same graph is read kōng as written; the two are not the same hole. What makes the word worth an entry is the other place it is used, where the chapter is arguing rather than defining: 腎汗出，逢於風，内不得入於藏府，外不得越於皮膚，客於𤣥府，行於皮裏，傳爲胕腫，本之於腎，名曰風水. The sweat of the kidney has come out and met wind; it can get neither back into the depots nor out past the skin, and so it lodges in the dark openings — the 玄府 is the place a thing is stuck when it can move in neither direction — and what is stuck there turns into the swelling the chapter is about. 後世 took the word further: 劉完素 made the 玄府 the gates by which qi and fluid go out and in, and found them everywhere, in the viscera, the skin and hair, the sinews and membranes, the bone and marrow, the nails and the teeth. The chapter itself needs none of that; it needs only a pore that will not let sweat past. The base text writes the graph 𤣥, an old form of 玄, and this is kept as written. The word occurs twice in this chapter and has not appeared in any chapter transcribed on the site before.
wèi qì
Defensive qi is the brisk, circulating part of yang that patrols the surface, skin and interstices, opening and closing the pores and meeting exterior evils first. When it disperses, the surface is left open.
shì qí
Double vision is chapter 80's account of why a man sees one thing as two. The eye is the meeting of the five depots' essence: 精之窠爲眼，骨之精爲瞳子，筋之精爲黑眼，血之精爲絡其窠，氣之精爲白眼，肌肉之精爲約束. These are wrapped and knotted with the essence of sinew, bone, blood and qi, and the whole is tied to the brain by the eye connection. Let evil strike the back of the neck when the body is empty, and it follows that connection into the brain; the brain turns, the connection is drawn tight, and 目系急則目眩以轉矣. Then 邪其精，其精所中不相比也，則精散，精散則視歧，視歧見兩物 — the essence is scattered, and scattered essence sees double. The explanation is mechanical throughout: two images are not a disease of the eye but a failure of the tie that makes the two eyes one.
tài xī
In the counting that opens chapter 18, the deep long breath is the thing that does not fit the rule. Five movements to a breath is the standard; but a person from time to time takes a longer breath, and the pulse moves once more within it. The chapter's word for counting that extra beat is 閏, the intercalary month inserted to keep the calendar true: the surplus is not an error but a regular one, and it must be counted in before the standard can stand. Later in the language 太息 comes to mean a sigh; in this chapter it is simply the breath by which the count is completed.
fǔ zàng
The paired word for the organs — the storehouses and what is stored — appearing in chapter 25 as the fifth of the five requirements: to know the examination of the depots, the viscera, the blood and the qi. It is worth noting that the chapter has already used 府 on its own in a different sense, for the ruined depot of §4; the two are the same graph and the reader has to keep them apart. Here 藏 is read zàng, not cáng.
gé
The chapter's oddest penalty. Striking the diaphragm does not kill quickly — 不過一歲必死, the person will die within a year — and yet it is listed with the strikes that kill in a day. It appears twice: once among the fatal strikes, and once in the rule for avoiding them, where the diaphragm's place is named as one of the places you may needle. It is the one structure in the chapter that is both lethal and passable.
chóng yáng zhī rén
The man in whom yang is doubled. The signs are all excess and all outward: blazing and high, quick of speech, lifting his feet high, the qi of heart and lung overfull, yang qi slippery, full and rising, so that his spirit stirs and his qi goes first. For the needle this is the fastest case in the chapter: the qi meets the needle as it enters. Set against him is the man of much yin and little yang, in whom qi sinks and goes slowly, so that many needlings are needed before he feels anything.
háo máo
The fine hair of the body's surface, and the outermost of the seven depths chapter 50 sets out. It occurs twice, both times inside the single phrase 毫毛腠理: illness that sits there is to be needled there, and the skin beneath it is not to be touched. The site's entry for 毛 (id 613) is the autumn quality of the pulse, a different word; 皮毛 (id 1126) is skin and body hair taken together as the lung's counterpart.
