The very root of the Governing Vessel. Changqiang (GV-1) sits at the base of the spine and acts as the starting fire of the entire Yang axis of the body — a powerful point for the lower orifices, the spine, and the deepest reserves of Yang energy.
Name & story
The name 长强 Changqiang means "Long and Strong" — or sometimes translated as "Lasting Strength". It is a beautiful and fitting name for the very first point on the Governing Vessel (GV), the channel that governs all Yang in the body. Think of it as the root of a great tree: hidden underground, out of sight, yet holding everything upright. Without a strong root, the tallest tree will not stand. In the same way, Changqiang anchors the Yang Qi that must travel all the way from the tip of the coccyx up through the whole spine to the crown of the head. The "long" speaks to that great journey; the "strong" speaks to the energy that begins it.
Point family & character
Changqiang (GV-1) is the first point on the Governing Vessel (GV), which governs all Yang in the body. It is the Luo Connecting point of the Governing Vessel, linking the GV to the Conception Vessel (CV). It is also the meeting point of the Governing Vessel with the Conception Vessel and the Kidney Meridian (KI).
Five-element dynamics
In Chinese medicine, the Governing Vessel is the "Sea of Yang Channels" — it collects and commands the Yang Qi of the entire body. GV-1 is the very starting point of this great river of Yang, and it also connects to the Kidney Meridian (KI), home of the body's deepest root energy, the Jing. So Changqiang sits at a remarkable crossroads: it touches the Kidney Jing, the source of both Yin and Yang, and it feeds the ascending Yang current of the spine. It is where the deepest and most fundamental energies of the body begin their upward journey.
Location
Find the midpoint between the tip of the coccyx (the very bottom of the tailbone) and the anus. The point sits in that small, sensitive space, exactly on the midline. It is most easily located and needled with the patient lying on their side or in a knee-chest position.
Anatomy & fascia
The point lies between the tip of the coccyx and the anus, in the midline.
Needling
The needle is inserted obliquely, angled upward toward the sacrum and parallel to it. The practitioner must avoid penetrating the rectum.
Safe depth
0.5–1 Cun.
Moxa, cupping & Tui Na
Moxa can be used at this point with care. It is particularly suited to warm and strengthen Yang in conditions of Cold and Yang Deficiency affecting the lower body. Massage of the coccygeal area is also practiced as a gentle home support technique.
Functions
Strengthens the Governing Vessel and tonifies Yang. Benefits the lower orifices and rectum. Calms the Shen and stops convulsions. Resolves Dampness and Heat in the lower Jiao. Treats prolapse and haemorrhoids. Strengthens the spine and the lumbar region.
Indications
Haemorrhoids, rectal prolapse, bleeding from the rectum. Diarrhoea, dysentery, constipation. Pain in the coccyx, sacrum and lumbar spine. Epilepsy and convulsions. Mania and mental disturbances. Urogenital disorders, seminal emission. Stiffness and pain along the spine.
Mind & spirit (Shen)
Because the Governing Vessel travels all the way from the base of the spine up through the back and into the brain, Changqiang sits at the very source of the channel that nourishes the mind. When the Yang Qi cannot rise freely — blocked at its root — the Shen above may be disturbed: epilepsy, mania, convulsions and states of mental agitation have traditionally been treated here. By anchoring and starting the upward flow of Yang, the point helps restore a stable foundation for the mind.
Point combinations
With GV-20 (Baihui) — a classic pairing along the full length of the Governing Vessel, connecting the root and the crown, used for prolapse, haemorrhoids and mental disturbances. With GV-4 (Mingmen) — to warm and strengthen the Yang of the spine and lower body. With GV-3 (Yaoyangguan) — for pain and weakness of the lumbar spine and sacral region.
Clinical spotlight
Changqiang (GV-1) holds a unique position in classical acupuncture: it is simultaneously the first point of the Governing Vessel, a Luo Connecting point, and a meeting of three channels. This makes it the energetic "seed" from which the entire Yang axis of the body grows. Clinically it is most prized for its direct and powerful action on the rectum and anus — haemorrhoids and rectal prolapse are its specialty — but its reach extends upward along the spine to the brain, accounting for its use in epilepsy and convulsive disorders, which have been recorded in Chinese medicine for over a thousand years. It is one of those points that is rarely the first choice in a modern clinic, but whose indications are very precise and whose effects, when used correctly, are deep.
The golden tip
A simple self-care measure: gentle massage around the base of the coccyx — with the fingertips, using small circular movements — can help ease discomfort from haemorrhoids or coccygeal pain. This is best done after a warm bath, when the area is relaxed. For any acute or persistent symptoms, always consult a practitioner.
