，须其火灭也。

第八节：从第一椎骨向下至尾骨节，共有四十二个穴位。
凡是五脏之气输注于背部的穴位，按压该处，若疼痛缓解且病邪随之消退，这才是正确的穴位。这类穴位适宜用灸法治疗，而不适宜用针刺；实证应当用泻法，虚证应当用补法。使用火疗进行补法时，不要吹灭火焰，需等待其自行熄灭。使用火疗进行泻法时，要快速吹旺火焰，并按压艾炷，直到火焰熄灭。

Section 8: From the first vertebra down to the sacrococcygeal joint, there are forty-two acupoints in total.
For those acupoints where the Qi of the five Zang organs (Five Viscera) emerges on the back, pressing the location should result in pain relief and resolution of the pathogenic factor; only then is it the correct acupoint. These points are suitable for moxibustion but not for acupuncture. For excess conditions, use the reducing method; for deficiency conditions, use the tonifying method. When using fire therapy for tonification, do not blow on the fire; wait for it to extinguish naturally. When using fire therapy for reduction, quickly blow on the fire to intensify it, press upon the mugwort, and wait for the flame to extinguish.
Dazhu (BL11), located below the first cervical/thoracic vertebra (depending on interpretation of 'first vertebra' in context of neck/back junction, typically C7/T1 area in modern mapping, but text says "neck first vertebra"), one and a half cun lateral to the spine, in the depression. It is the meeting point of the Foot-Taiyang Bladder Meridian and Hand-Taiyang Small Intestine Meridian. Puncture depth: 0.3 cun; retain needle for seven breaths; moxibustion: 7 cones.

Feishu (BL13), located below the third thoracic vertebra, one and a half cun lateral to the spine. Puncture depth: 0.3 cun; retain needle for seven breaths; moxibustion: 3 cones. (Note from *Qifu Lun*: This is the convergence of the Back-Shu points of the five Zang organs and the Foot-Taiyang Bladder Meridian.)
