At a glance

Pinyin: chū xuè wù qì
Simplified: 出血恶气
Literal: 出 is going out and up — 說文 takes it from a plant pushing through the ground — and here it is causative: bring out, let. 惡 is the difficult graph. It is usually the adjective for bad, but 說文 glosses it as 過也, a fault, and read wù it is the verb to dislike, to hold something unfitting. Chapter 24 settles the reading decisively: the six rules at the end let out whatever the channel is plentiful in and withhold whatever it is scant in, and the pattern holds in all six without exception. 惡 is therefore the verb of refusal, not the adjective of badness.
Shuowen: 《說文解字》：出，進也。象艸木益滋上出達也；惡，過也。从心亞聲。本篇「惡」讀 wù，忌也、不宜也，非敗惡之惡（è）。本篇之目：剌太陽出血惡氣，剌少陽出氣惡血。

In brief

The chapter’s closing rule, and the reason the opening table matters: at each of the six channels you let out what that channel is plentiful in, and you do not touch what it is scant in. Yang brightness, plentiful in both, may be let of both; greater yang, plentiful in blood, may be bled but its qi is not to be taken; lesser yang, lesser yin and greater yin, plentiful in qi, may be let of qi but not of blood; ceasing yin, plentiful in blood, may be bled but not let of qi. The reading of 惡 as wù, to hold unfitting, rather than è, bad, is forced by this pattern — it holds six times out of six, and no reading of ‘evil blood’ or ‘evil qi’ produces a rule at all.

剌陽明出血氣，剌太陽出血惡氣，剌少陽出氣惡血，剌太陰出氣惡血，剌少陰出氣，惡血，剌厥陰出血，惡氣也。刺阳明出血气，刺太阳出血恶气，刺少阳出气恶血，刺太阴出气恶血，刺少阴出气，恶血，刺厥阴出血，恶气也。

Puncture yang brightness and both blood and qi may be let; puncture greater yang and blood may be let but the qi is not to be touched; puncture lesser yang and qi may be let but not the blood; puncture greater yin and qi may be let but not the blood; puncture lesser yin and qi may be let, but not the blood; puncture ceasing yin and blood may be let, but not the qi.

本篇末六條刺法，是開卷「常數」之推演，而「惡」字之讀即由此而定。太陽多血少氣，故「出血惡氣」；陽明多氣多血，故「出血氣」；少陽少血多氣，故「出氣惡血」；太陰多氣少血，故「出氣惡血」；少陰少血多氣，故「出氣，惡血」；厥陰多血少氣，故「出血，惡氣」。六條之中，所出者必其多者，所惡者必其少者，無一例外——則「惡」當讀 wù（忌也、不宜也）無疑。舊亦讀 è，以「惡氣」「惡血」為敗惡之氣血；然如此則六條不成其為規則，今不從。「出」讀 chū，《說文》訓「進也」，象草木上出，此則使之出。底本六條皆作「剌」（音 là），當讀「刺」（cì），說見本站「灸刺」條。

How it has been translated

Every rendering below is a decision about which reader is being addressed. There is no neutral option.

Wiseman & Feng	drain blood, [but] not qi	They read 惡 as the negation it functions as, which is the correct reading.
Unschuld	let blood, [and] avoid the qi	He renders 惡 as avoid, which is clear but softens the sense of prohibition.
This site	let blood, shun qi	惡 read wù is not 'avoid' in the sense of steering around, but 'hold it unfitting' — the text is laying down what may not be done. The six-channel pattern makes the reading certain: what is let is always what the channel has plenty of, and what is shunned is always what it is short of.
