The calm guardian of the inner landscape. Zhubin (KI-9) clears Phlegm, settles the Shen and purifies what is turbid — when the mind is agitated, the heart is restless, and something muddied has crept into the body or the spirit, this point gently clears the way.
Contraindications
Zhubin (KI-9) is a safe point on the lower leg with no special contraindications. Maintain clean needling technique and stay within the recommended depth.
Name & story
The name 筑宾 Zhubin is often translated as 'Guest House' or 'Esteemed Guest' — 宾 (bīn) means a guest or honoured visitor, and 筑 (zhù) refers to building or establishing a dwelling. One way to read the name is this: the point is a place where something comes to rest and be held safely. In the context of the Kidney channel and its deep relationship with the Yin Qiao Mai and Chong Mai, it is as if the pure Qi of the Kidneys offers shelter to the Shen — welcoming it, steadying it, keeping it from wandering into chaos.
Point family & character
Zhubin (KI-9) sits on the Kidney Meridian (KI). Its most important character is that it is the Xi Cleft point of the Yin Wei Mai — one of the eight Extraordinary Vessels. This gives it a special power to address acute or painful conditions along that vessel's pathway, as well as its associated emotional and Shen disturbances.
Five-element dynamics
The Kidney belongs to the Water element — the deepest, most hidden element in the body, governing the root of all Yin and Yang. Water, when it is clear, nourishes the mind and anchors the Shen. But when Water becomes clouded — by Phlegm, by turbidity, by accumulated toxins of the body or the mind — it can no longer perform its quiet, steadying work. Zhubin acts like a filter at the heart of the Water element: it draws out what is impure, clears what has grown turbid, and restores the stillness that Water, at its best, always carries.
Location
Find the midpoint between KI-3 (at the inner ankle) and KI-10 (at the inner knee crease). Zhubin (KI-9) is approximately 5 Cun above the tip of the medial malleolus, on the line connecting KI-3 to KI-10, at the lower border of the gastrocnemius muscle belly.
Anatomy & fascia
The point lies on the medial side of the lower leg, in the muscular belly of the gastrocnemius (specifically at the medial head), near the soleus.
Needling
The needle is inserted perpendicularly, straight into the muscle. A local aching or spreading sensation (de qi) is expected.
Safe depth
Safe depth — 0.5–1 Cun.
Moxa, cupping & Tui Na
Moxa is appropriate when there is Cold or Yang Deficiency in the presentation. Gentle massage along the inner calf, following the Kidney channel upward, can complement needling and is suitable for home use. The point is also well suited to acupressure for grounding and calming the Shen.
Functions
Clears Phlegm and calms the Shen; resolves turbidity and toxins from the body and mind. Benefits the Yin Wei Mai as its Xi Cleft point. Regulates and steadies the Kidney channel. Treats accumulation of Phlegm-Heat disturbing the Heart and mind.
Indications
Mental and emotional disturbances, especially those involving Phlegm — anxiety, agitation, mania, epilepsy and convulsions. Abdominal pain and distension. Pain along the medial aspect of the lower leg. Vomiting and digestive discomfort from turbid accumulation. Conditions of toxin accumulation — historically noted for its role in clearing poisons. Disorders of the Yin Wei Mai pathway.
Mind & spirit (Shen)
Zhubin has a particular affinity for the troubled mind — not the kind of sadness that comes from emptiness, but the kind of restlessness and confusion that comes from something turbid clogging the channels. When Phlegm mists the Heart and the Shen loses its mooring, a person may feel irrationally fearful, mentally scattered, or even manic. Zhubin, as the Xi Cleft of the Yin Wei Mai, reaches into that hidden interior and clears the obstruction. It is a point for those moments when the mind seems to be overcome by something that does not belong there — and needs gently clearing out.
Point combinations
With PC-5 (Jianshi) and HT-7 (Shenmen) — to clear Phlegm-Heat from the Heart and calm severe Shen disturbance or mania. With ST-40 (Fenglong) — the great Phlegm-resolving point — to strengthen the clearing of turbidity from the body and mind. With SP-4 (Gongsun) and PC-6 (Neiguan) — to regulate the Chong Mai and Yin Wei Mai together when there is emotional turmoil with a physical component in the chest or abdomen.
Clinical spotlight
Zhubin (KI-9) is one of the more quietly powerful points on the Kidney channel — rarely the first point a student learns, but valued by experienced practitioners for situations where Phlegm or turbidity is disturbing the Shen. Its role as the Xi Cleft of the Yin Wei Mai makes it particularly relevant in acute emotional crises that have a deep, constitutional root — where the problem is not simply surface agitation but something that has penetrated into the Yin level of the body. Some classical texts also reference this point in the context of clearing accumulated toxins, giving it a purifying dimension that extends beyond the purely psychological.
The golden tip
To find Zhubin, sit with your leg relaxed and trace the inner edge of the calf upward from the ankle — about two-thirds of the way from the ankle to the knee, at the fleshy inner edge of the calf muscle. Firm, circular massage here for one to two minutes on each leg can help ease restlessness, mental fog and inner tension. If you feel tightness along the inner calf, working slowly up the Kidney channel from ankle to knee is a simple and grounding self-care practice.
