A quiet but powerful point on the neck, Tianrong (SI-17) clears the throat, benefits the ears, and releases swelling and stagnation in the neck region — wherever Phlegm, Heat or Qi Stagnation gathers in the area below the jaw.
Name & story
The name 天容 Tianrong means 'Heavenly Appearance' or 'Appearance of Heaven'. Tian means 'heaven' or 'sky', and rong means 'appearance', 'countenance', or 'to contain'. The neck is considered the gateway between heaven (the head, the seat of the mind and senses) and the rest of the body. This point sits in that transitional zone — governing what is received and expressed through the throat and face, including the voice, the ears, and the act of swallowing. Its name hints at how the heavenly region presents itself: clearly, openly, without obstruction.
Point family & character
SI-17 belongs to the Small Intestine Meridian (SI). It is located in the neck region and is closely associated with local conditions of the throat, jaw, ears and lymphatic structures of the neck.
Five-element dynamics
The Small Intestine Meridian (SI) belongs to the Fire element and is paired with the Heart. While the Heart governs the Shen and the inner life, the Small Intestine is the great separator — it sorts the clear from the turbid. When this sorting function breaks down in the neck region, things accumulate: Phlegm, swelling, heat in the throat. Tianrong (SI-17), sitting right at the angle of the jaw, is ideally placed to resolve exactly that kind of local accumulation and restore the clarity — the 'heavenly appearance' — of this region.
Location
Find the angle of the jawbone (mandible). SI-17 sits just behind that bony angle, in the depression anterior to the sternocleidomastoid muscle. It is roughly level with SI-16 and close to the path of the Small Intestine Meridian (SI) as it ascends the neck toward the face and ear.
Anatomy & fascia
The point lies posterior to the angle of the mandible (the jaw), in front of the sternocleidomastoid muscle. Important structures in the area include the external jugular vein, the parotid gland, and branches of the facial and cervical nerves.
Needling
The needle is inserted perpendicularly, directed carefully in the soft depression behind the angle of the jaw. The area is rich in vessels and nerves, so a steady, controlled insertion is important.
The golden tip
If you feel tightness or swelling in the sides of the neck below the jaw, gently pressing the area behind the angle of the jawbone with a fingertip — in the soft hollow just in front of the sternocleidomastoid muscle — can bring some relief. Use slow, gentle circular pressure; do not press hard. This is also a good area to warm gently with your hand if the throat feels cold and tight.
