DU-16 (Feng Fu) Wind Mansion

What does DU-16 Feng Fu do?

Feng Fu DU-16 is the Governing Vessel's great point for wind — the “mansion” the classics say wind enters and lodges in — and it is one of only two points classified as a Point of the Sea of Marrow. It sits on the midline at the base of the skull, where Sacred Lotus sources & references record the Governing Vessel meeting the Yang Linking Vessel. Its recorded range follows from that position: the head, the brain, the neck, and disorders the tradition attributes to wind.

• Eliminates wind — the first recorded action and the one the name states. It covers both exterior wind, the pattern of a beginning common cold with occipital headache and a stiff neck, and interior wind, the tremor, dizziness and sudden loss of function the tradition groups under windstroke.
• Nourishes the Sea of Marrow and benefits the head and brain — the classification-driven action. In Chinese medicine the brain is the Sea of Marrow, and DU-16 and Bai Hui DU-20 are the two points our references classify as its points. This is the recorded basis for its use in dizziness, poor memory, heaviness of the head and the sequelae of windstroke.
• Benefits the neck and releases the occiput — the local action, for rigidity of the nape, occipital pain and inability to turn or bend the head.
• Calms the spirit — recorded for mania, agitation, epilepsy and disturbed mental states. It is one of Sun Si-miao's Ghost Points, assembled for exactly these presentations, where it carries the name Gui Zhen, “Ghost Pillow”.
• Benefits the tongue and voice — recorded for loss of speech after windstroke, a heavy or stiff tongue, and sore throat. This action links it to its immediate neighbour Ya Men DU-15, “Mute's Gate”.
• Clears the sense orifices — as a Point of the Window of Heaven, one of the group whose shared recorded function is restoring communication between the head and the body.

What is DU-16 Feng Fu used for?

Feng Fu DU-16 is used above all for headache at the back of the head, for a stiff neck, and for disorders the tradition attributes to wind. The indications carried in Sacred Lotus sources & references are set out below, alongside those recorded in the standard reference literature. They describe traditional use, not proven treatment, and this point carries the substantial safety cautions set out under needling — it is not a point for self-treatment in any form.

• Occipital headache and headache of the whole head
• Rigidity and pain of the neck; inability to turn the head
• Common cold with aversion to cold, fever and body aches
• Dizziness and vertigo
• Blurred vision and dim vision
• Nosebleed (epistaxis)
• Sore throat and loss of voice
• Windstroke, hemiplegia and loss of speech following windstroke
• Heaviness or numbness of the tongue; difficulty speaking
• Difficulty swallowing after stroke
• Epilepsy, convulsion and mania
• Poor memory, mental confusion and agitation
• Pain and stiffness of the upper back and shoulders
• Nosebleed and nasal congestion
• Febrile disease without sweating

Where is DU-16 Feng Fu, and how is it used in practice?

Feng Fu sits on the midline at the very top of the neck, in the hollow immediately below the external occipital protuberance — the bump you can feel at the back of the skull — about one cun above the posterior hairline. Both of our location records place it there, described from the two directions: one from the hairline, one from the bony landmark. A reader should understand what that position means before anything else: the hollow it sits in is the soft gap between the skull and the first vertebra, and the foramen magnum, the great opening through which the brainstem passes, lies directly beneath it. That anatomy governs everything about how the point is treated.

Which points is DU-16 combined with?

• For an invasion of exterior wind — the classical opening combination is Feng Fu DU-16 with Feng Chi GB-20 and Feng Men BL-12, the three points whose names all carry the character for wind, with Lie Que LU-07 and He Gu LI-04 added to release the exterior. A complex-network analysis of 311 published studies of acupuncture for cervicogenic headache found exactly this pattern in the syndrome data: the wind-cold pattern drew Da Zhui DU-14, Feng Men BL-12 and He Gu LI-04, while the Tai Yang pattern drew Tian Zhu BL-10 and Feng Fu DU-16 (Zhen Ci Yan Jiu 2025;50(10):1199–1210, PMID 41116994).
• For occipital headache and neck rigidity — with Feng Chi GB-20 on either side of it and Tian Zhu BL-10 beside that, and with the distal points Hou Xi SI-03, the confluent point of the Governing Vessel, and Kun Lun BL-60. A study of 2,200 ancient Chinese medical books identified Feng Chi GB-20 as by far the commonest partner point recorded for Feng Fu (Zhen Ci Yan Jiu 2015;40(2):170–3, PMID 26054206).
• For windstroke and its sequelae — with Bai Hui DU-20, the other Point of the Sea of Marrow, and with Shui Gou DU-26 and Nei Guan P-06.
• For speech and swallowing difficulty after stroke — with Ya Men DU-15 immediately below it and Lian Quan REN-23 at the front of the throat. This is the combination that has actually been trialled: sixty patients with post-stroke dysphagia received electroacupuncture at Feng Fu DU-16 and Lian Quan REN-23 alongside conventional treatment and rehabilitation (Zhongguo Zhen Jiu 2018;38(2):115–9, PMID 29473351).
• Among the Sea of Marrow points — Sacred Lotus sources & references classify only two points this way, Feng Fu DU-16 and Bai Hui DU-20, and they are frequently used together where the brain rather than the channel is the object.

Where does DU-16 sit among its category peers?

DU-16 carries four classifications, which is unusual. As a Point of the Sea of Marrow it pairs with Bai Hui DU-20. As a Meeting Point of the Governing and Yang Linking Vessels it shares that meeting with Ya Men DU-15, its immediate neighbour — the two are the Du Mai's only meetings with the Yang Wei. As a Point of the Window of Heaven it belongs to the group held here that rings the neck and throat: Tian Zhu BL-10, Ren Ying ST-09, Fu Tu LI-18, Tian Chuang SI-16, Tian Rong SI-17, Tian You SJ-16, Tian Tu REN-22, Tian Fu LU-03, Tian Chi P-01. And as a Sun Si-miao Ghost Point it belongs with Shui Gou DU-26, Shen Mai BL-62 and the rest of that group. The practical consequence is that DU-16 is reached for both as a local neck point and as a point directed at the brain — and its position is what makes it so useful and so exposed at the same time.

Where is DU-16 located?

• A Manual of Acupuncture (p. 548): On the midline at the nape of the neck, in the depression immediately below the external occipital protuberance.
• Chinese Acupuncture and Moxibustion (p. 232): 1 cun directly above the midpoint of the posterior hairline, directly below the external occipital protuberance, in the depression between m. trapezius of both sides.

How is DU-16 Feng Fu needled, and why is it the most safety-sensitive point in the canon?

Stated plainly and first: Feng Fu DU-16 lies on the midline directly over the foramen magnum, and the medulla oblongata — the part of the brainstem that governs breathing and heart rate — lies immediately deep to it. It is the point most consistently singled out in the classical and modern literature alike as one where deep insertion must not occur, and the injuries recorded in the region are among the gravest documented anywhere in acupuncture. Everything set out below is recorded as neutral reference data describing what the textbooks and the published anatomical and case literature state. It is not instruction, this page does not teach technique, and needling here is carried out only by a qualified, licensed practitioner. It is emphatically not a point for self-treatment, pressure devices or untrained hands.

The angle the texts record — the safety-critical variable

Direction matters more than depth at this point. The standard references record the needle being directed toward the mandible — that is, downward and forward toward the jaw. They are explicit that it is not directed upward. The reason is geometric: an upward trajectory from this hollow points into the foramen magnum, whereas a trajectory toward the jaw runs into the bone and muscle of the upper neck and away from the opening.

• Deadman & Al-Khafaji (p. 548) record insertion directed toward the mandible, 0.5 to 1 cun, with an explicit caution against needling upward or deeply because of the medulla oblongata beneath.
• Sacred Lotus sources & references record perpendicular insertion of 0.5 to 0.8 inch, with the note that deep puncture is not advisable and that the medullary bulb lies in the deep layer, so that special attention must be paid. Chinese Acupuncture & Moxibustion (p. 232) carries the same caution.
• Moxibustion is recorded by the classical sources as contraindicated or discouraged at this point in several texts, and it is not a point at which moxa is routinely used.

The measured anatomy — how much margin there actually is

This is not caution by habit. The depth from the skin at Feng Fu to the structures beneath has been measured directly, and the figures are the clearest single statement of why the recorded depth is shallow.

• Computed-tomography study of safe needling depth at Feng Fu. Forty-one adult volunteers were grouped by body type and the needling depth at Fengfu GV16 measured on CT. The safe depth of perpendicular insertion differed by build: 27.73 ± 3.45 mm in the thin group, 30.78 ± 2.90 mm in the moderate group and 33.39 ± 4.27 mm in the heavier group — that is, roughly three centimetres of tissue in an average adult before the dangerous depth is reached, and appreciably less in a slight person. The authors proposed that a safe working figure is no more than about 75 per cent of the measured dangerous depth (Zhongguo Zhen Jiu 2008;28(1):47–8, PMID 18257190).
• The neighbouring point has been measured the same way. Ya Men DU-15, a little below Feng Fu on the same midline and equally close to the medulla, was studied by MRI, with the dangerous depth defined as the distance from the skin to the spinal dura mater. Safe depth varied significantly with sex, body mass index and skull dimensions, the three together explaining about 57 per cent of the variation (J Pharmacopuncture 2014;17(1):70–3, PMID 25780692, PMC4331983). A later study examined safe depth at Ya Men specifically in patients with atlantoaxial dislocation, where the margin is altered by the underlying pathology (Zhongguo Zhen Jiu 2019;39(6), PMID 31190499).
• The recurring finding across the safe-depth literature is variation. A review of 33 studies of safe needling depth across the body concluded that measured depths are markedly inconsistent between subject groups and measuring methods, and called for properly designed work on each point (J Altern Complement Med 2011;17(3):199–206, PMID 21417806). A single textbook figure is therefore a conservative floor for the population, not a target for an individual.

What the case literature documents

Injuries to the medulla and upper cervical cord from acupuncture needles in this region are documented in the peer-reviewed neurosurgical literature, and they are the reason this point is taught with more care than any other.

• The largest case series. A neurosurgical review retrospectively studied 26 patients with cervical or brain injuries from acupuncture needles. Embedded needles were the commonest cause (15 patients, 57.7 per cent) and accidentally broken needles the second (11 patients, 42.3 per cent); five cases (19.2 per cent) followed self-acupuncture. Sixteen patients (61.5 per cent) developed symptoms more than thirty days after the event, 23 (88.5 per cent) had sensory deficits and 11 (42.3 per cent) motor weakness. Twenty-one underwent surgical removal, of whom ten showed recovery; none of the conservatively treated patients improved. The authors' conclusion was blunt: embedded-needle acupuncture and self-acupuncture are extremely dangerous (Miyamoto S et al., World Neurosurg 2010;73(6):735–41, PMID 20934166, DOI 10.1016/j.wneu.2010.03.020).
• Needle migration into the brainstem is documented repeatedly. Published cases include migration of an acupuncture needle into the medulla oblongata (Eur Spine J 1996;5(2):137–9, PMID 8724197), a migrated needle found in the medulla (Arch Neurol 2004;61(10):1608, PMID 15477518), and medulla oblongata injury caused by an acupuncture needle, published as a warning about serious complications (J Neurol 2011;258(11):2093–4, PMID 21544563).
• The vertebral artery is in the same territory. A 2022 case describes a broken needle that migrated through the posterior cervical skin and the atlanto-occipital junction, its tail lying against the horizontal loop of the vertebral artery and its tip in the premedullary cistern beside the medulla; it had penetrated the adventitia of the intradural vertebral artery and required emergency intradural surgical removal. The authors record it as the first radiologically confirmed penetrating vertebral-artery injury from a migrated acupuncture needle (Abe D et al., Nagoya J Med Sci 2022;84(4):890–899, PMID 36544595, PMC9748321). Our record for Feng Chi GB-20, immediately lateral to this point, covers the same vertebral-artery hazard.
• The anatomical warning is long-standing. A postmortem and literature study of traumatic complications of acupuncture concluded that the anatomy at several points is such that needles can reach vulnerable structures, and recorded deaths from pneumothorax and cardiac tamponade among the traumatic complications of acupuncture generally (Peuker ET et al., Arch Fam Med 1999;8(6):553–8, PMID 10575398).

Deaths — what the record does and does not show

This deserves precision rather than emphasis. Deaths following acupuncture are recorded in the aggregate reviews of the Chinese case literature: a systematic review of 115 Chinese-language articles reporting 479 adverse events found 14 deaths, with subarachnoid haemorrhage among both the most frequent and the most serious traumatic complications (Zhang J et al., Bull World Health Organ 2010;88(12):915–921C, PMID 21124716, PMC2995190), and a companion review of 1,038 cases across 167 articles from 1956 to 2010 recorded 35 deaths across the series, attributing the events chiefly to improper technique and judging most avoidable (He W et al., J Altern Complement Med 2012;18(10):892–901, PMID 22967282). Those reviews report deaths from central-nervous-system injury among the causes, but they aggregate by complication rather than by point, so they do not attribute a death to Feng Fu specifically. The individually published case reports of medulla and upper-cord injury cited above describe serious injury and, in several instances, recovery after surgery — not death. The accurate statement is therefore this: the hazard at DU-16 is real, measured and grave, and the injuries documented in this region are among the most serious in the whole adverse-event literature; but the published record does not contain a case attributing a death to needling at this named point, and this page will not assert one.

The risk in proportion

These events are rare. A meta-analysis of prospective clinical studies estimated serious adverse events at approximately 1 per 10,000 patients and around 8 per million treatments, with about half of all recorded events being bleeding, pain or flare at the needle site, placing acupuncture among the safer treatments in medicine (Bäumler P et al., BMJ Open 2021;11:e045961, PMID 34489268). Both things are true at once, and both belong on this page: the overall rate is low, and the small number of catastrophic events that do occur cluster at a handful of anatomically exposed points, of which Feng Fu is the most exposed of all. Two features of the case literature are worth carrying away — most of the recorded brainstem injuries involved embedded or broken needles rather than ordinary needling, and most declared themselves weeks later rather than at the time.

What does the name Feng Fu mean?

Feng Fu means “Wind Mansion” or “Wind Palace” — feng, wind, and fu, a mansion, official residence or seat of government. The name is stronger than it looks. Fu is not simply a house: it is the administrative seat, the place from which something is governed. The classics did not merely say wind arrives at the nape of the neck; they said this is where it takes up residence and rules. That is the reason the point stands at the head of the “wind” group and the reason the classical instruction to keep the back of the neck covered in cold weather is attached to it. The point is also recorded under the name She Ben, “Tongue Root”, which matches its recorded use for the tongue and the voice, and as Gui Zhen, “Ghost Pillow”, in the Ghost Point series.

Which other points carry “wind” in their names?

Feng Fu belongs to a small named group, every member of which is held here and every one of which sits on the neck, the upper back or behind the ear — the region the classics identify as wind's point of entry:

• Feng Fu DU-16, “Wind Mansion” — on the midline below the occiput. This page.
• Feng Chi GB-20, “Wind Pool” — in the hollow to either side of it, at the same level.
• Feng Men BL-12, “Wind Gate” — on the upper back beside the second thoracic vertebra.
• Yi Feng SJ-17, “Wind Screen” — in the depression behind the earlobe.

They are frequently used together at the onset of an exterior invasion, and the arrangement is deliberate: mansion on the midline, pools either side, gate below, screen in front.

Why does the Sea of Marrow classification matter?

The Ling Shu describes four Seas, each with its own points: the Sea of Qi, the Sea of Blood, the Sea of Water and Grain, and the Sea of Marrow, which is the brain. Sacred Lotus sources & references classify only two points as Points of the Sea of Marrow — Feng Fu DU-16 at its lower pole and Bai Hui DU-20 at its upper. The classification is the classical statement that this point addresses the brain itself rather than the channel passing over it, and it accounts for the indications on its list that concern memory, dizziness, consciousness and speech rather than the neck. It is worth noticing the uncomfortable symmetry: the anatomical reason the classics assigned this point to the brain is the same anatomical reason it is the most hazardous point on the body.

Is there research on DU-16 Feng Fu?

Feng Fu has a modest but genuinely point-specific research literature, and — unusually — a substantial documentary and anatomical literature about the point itself. The honest summary is that the strongest work concerns its history and its safety rather than its clinical effect.

• Documentary study of classical use. A search of 2,200 ancient Chinese medical books from the Qin to the Qing dynasties recovered 277 records of Feng Fu covering 61 disorders across internal medicine, surgery, paediatrics and the sense organs, plus 147 records of the needling and moxibustion methods used at it. Used alone, the point was recorded most often for disorders of exterior origin — common cold, neck pain, headache, epilepsy, mania, dizziness, loss of voice — and the commonest partner point was Feng Chi GB-20 (Zhen Ci Yan Jiu 2015;40(2):170–3, PMID 26054206). This is one of the better pieces of historical point research and it corresponds closely to the indications our own record carries.
• Anatomical safety research. The CT safe-depth study described under needling (PMID 18257190) is directly about this point. For Feng Fu, as for several of the most exposed points, the safety literature is the point-specific research literature.
• Post-stroke dysphagia — the one clinical trial. Sixty patients with dysphagia after stroke were randomised to low-frequency (2 Hz) or high-frequency (100 Hz) electroacupuncture at Feng Fu DU-16 and Lian Quan REN-23 on top of conventional treatment and rehabilitation, assessed by videofluoroscopic swallowing study. Both groups improved; the low-frequency group improved more, with a total effective rate of 93.3 per cent against 66.7 per cent (Zhongguo Zhen Jiu 2018;38(2):115–9, PMID 29473351). Sixty patients, no sham arm, and both arms received acupuncture — this compares two stimulation frequencies, not acupuncture against no acupuncture.
• Animal work. Feng Fu appears in preclinical protocols rather than alone: acupuncture at Ya Men GV15, Fengfu GV16, Bai Hui GV20 and He Gu LI4 was reported to reduce brain microglial activation in a rat traumatic brain injury model (J Tradit Chin Med 2020;40(2):267–274, PMID 32242392), and electroacupuncture at Fengfu GV16 with Tai Chong LR3 has been studied in rat models of Parkinson's disease (Zhen Ci Yan Jiu 2013;38(3):198–201, PMID 24006664; Zhen Ci Yan Jiu 2019;44(12):873–7, PMID 31867905).

What is not there: no adequately powered clinical trial isolates DU-16, and none of its headache, wind or Sea of Marrow indications has been tested at this point on its own. Given the point's hazard profile that absence is unsurprising, and it should be read as a gap in the evidence rather than as evidence either way.

How does Feng Fu compare with the points around it?

Feng Chi GB-20 lies in the hollows to either side at the same level and is by far the more used of the two; it shares the wind indications and much of the hazard, and its record here covers the vertebral artery in this region. Ya Men DU-15 lies just below Feng Fu on the same midline, shares its meeting with the Yang Linking Vessel, is directed at the tongue and voice as its name “Mute's Gate” says, and carries the same brainstem caution — the two are the pair of Governing Vessel points that must be treated with the greatest care. Nao Hu DU-17 sits immediately above it on the occipital bone, where the skull provides a floor the needle cannot pass, which makes it anatomically far less exposed. Tian Zhu BL-10 lies lateral to the midline and is the Bladder-channel neighbour, sharing the neck and occipital indications and the Window of Heaven classification. Bai Hui DU-20 at the vertex is its partner as a Point of the Sea of Marrow and is the safe alternative when the object is the brain rather than the neck. The plain comparative point is this: several of these neighbours cover much of Feng Fu's clinical ground with less anatomical exposure, and that is a large part of why the point is treated with restraint.
