黃帝問於歧伯曰：首面與身形也，屬骨連筋，同血合於氣耳。天寒則裂地凌冰，其卒寒或手足懈惰，然而其面不衣，何也？歧伯答曰：十二經脉，三百六十五絡，其血氣皆上于面而走空竅，其精陽氣上走於目而爲睛，其别氣走於耳而爲聽，其宗氣上出於鼻而爲臭，其濁氣出於胃，走脣舌而爲味。其氣之津液，皆上熏于面，而皮又厚，其肉堅，故天氣甚寒不能勝之也。

Huang Di asked Qi Bo: Head and face with the body and form — they are joined to the bones, linked by the sinews, share the blood and unite in the qi, that is all. When heaven is cold it cracks the earth and piles up ice, and in sudden cold the hands and feet may be slack and useless; yet the face needs no clothing. Why is this? Qi Bo answered: In the twelve channels and the three hundred and sixty-five network vessels the blood and qi all go up to the face and enter the hollow openings. The essence-yang qi goes up to the eyes and makes sight; the separated qi goes to the ears and makes hearing; the ancestral qi goes out at the nose and makes smell; the turbid qi goes out from the stomach to the lips and tongue and makes taste. The fluids of this qi all steam upward to the face, and moreover its skin is thick and its flesh firm, so that the cold of heaven, however severe, cannot overcome it.
「空竅」本篇1見，在「其血氣皆上于面而走空竅」一句。「竅」字1見，唯此而已。空即孔，故《素問》或作「孔竅」；此篇作「空」，與「空中」之空同字而異讀。
歧伯曰：心者，五藏六府之主也；目者，宗脉之所聚也，上液之道也；口鼻者，氣之門户也。故悲哀愁憂則心動，心動則五藏六府皆摇，摇則宗脉感，宗脉感則液道開，液道開故泣涕出焉。液者，所以灌精濡空竅者也，故上液之道開則泣，泣不止則液竭，液竭則精不灌，精不灌則目無所見矣，故命曰奪精。補天柱經俠頸。

Qibo said: the heart is the master of the five viscera and six receptacles; the eye is where the ancestral vessels gather and is the road of the upper fluids; mouth and nose are the doors of qi. So grief, sorrow and worry move the heart; the heart moved, the five viscera and six receptacles all shake; shaking, the ancestral vessels are stirred; stirred, the fluid road opens; the fluid road open, tears and mucus flow. Fluid is what irrigates the essence and moistens the empty orifices; so when the road of the upper fluids opens there are tears, and tears that do not stop exhaust the fluid; the fluid exhausted, the essence is not irrigated; the essence not irrigated, the eye sees nothing. So it is named seizing the essence. Tonify the Tianzhu channel beside the nape.

Qi Bo said: The stomach qi flows upward to the lungs. Its fierce qi, which rushes up to the head, follows the throat up into the empty orifices, follows the eye system into the brain, emerges at the cheek, descends to Kezhuren, follows the jaw cart, joins the yangming, and goes down together to Renying. This is the stomach qi that branches away into the yangming.
