Complete Paraphrase
Note: In the original text, characters such as "妨伯" (fáng bó), "荣对" (róng duì), "股理始流" (gǔ lǐ shǐ liú), "发颇斑白" (fà pō bān bái), "苦化悲" (kǔ huà bēi), and "懈情" (xiè qíng) are transcriptional errors. They have been emended according to standard editions to "岐伯" (Qí Bó), "营卫" (yíng wèi, Nutritive and Defensive Qi), "腠理始疏" (còu lǐ shǐ shū, the interstitial spaces begin to loosen), "发鬓颁白" (fà bìn bān bái, hair at the temples turns gray), "苦忧悲" (kǔ yōu bēi, afflicted by worry and sorrow), and "懈惰" (xiè duò, lethargic and listless) respectively.
The Yellow Emperor asked Qi Bo: When a person is first born, what qi serves as the foundation of life, and what serves as the external defense? What is lost that causes death, and what is obtained that allows life? Qi Bo replied: The mother's blood serves as the foundation (jī), and the father's essence serves as the shield (shǔn) (protection). Losing Spirit (shén) brings death; obtaining Spirit brings life. The Yellow Emperor asked: What is Spirit? Qi Bo said: When blood and qi are harmonized, the Nutritive and Defensive (yíng wèi — the qi responsible for nourishment and defense) circulate freely, the five viscera have fully formed, spirit-qi resides in the heart, and both soul (hún) and corporeal soul (pò) are complete — only then is one a complete person.
The Yellow Emperor asked: People's lifespans differ in length — some are short-lived, some die suddenly, some suffer prolonged illness without recovery. I wish to hear the reasoning behind this. Qi Bo said: When the five viscera are firm and secure, blood and vessels are harmonious, muscles are smooth and supple, the skin is dense and compact, the Nutritive and Defensive qi circulate without losing their normal rhythm, breathing is fine and slow, 💨 qi moves according to regular cycles, the six bowels digest food and drink, and fluids are properly distributed — all functions operate normally, and thus life can be long.
The Yellow Emperor asked: What enables a person to live to one hundred years of age and then die? Qi Bo said: When the philtrum groove is deep and long, the facial bones and muscles are high, thick, and well-proportioned, Nutritive and Defensive qi are harmonious, the upper, middle, and lower regions of the face along with the Three Mile points are full and raised, the bones are prominent and the muscles are full and strong — therefore the person can live to one hundred years and then pass away.
The Yellow Emperor asked: Can you explain the flourishing and decline of the body's qi from birth to death? Qi Bo said: At ten years of age, the five viscera begin to stabilize, blood and qi are already unobstructed, and qi tends to be concentrated in the lower part of the body — therefore the child loves to run. At twenty years of age, blood and qi begin to flourish, and the muscles are growing — therefore the person loves to walk briskly. At thirty years of age, the five viscera are largely settled, the muscles are firm, and the blood and vessels are full — therefore the person loves to walk at a leisurely pace. At forty years of age, the five viscera, six bowels, and twelve main channels have all reached their peak and begun to plateau; the interstitial spaces begin to loosen, the glow of the complexion begins to decline, the hair turns gray at the temples, and blood and qi are stable and no longer inclined to movement — therefore the person loves to sit. At fifty years of age, liver qi begins to decline, the liver lobes begin to thin, bile begins to decrease, and the eyes begin to see unclearly. At sixty years of age, heart qi begins to decline, the person becomes prone to worry and sorrow, blood and qi become lethargic and listless — therefore the person loves to lie down. At seventy years of age, spleen qi becomes deficient, and the skin becomes withered and dry. At eighty years of age, lung qi declines, the corporeal soul disperses, and therefore speech becomes prone to error. At ninety years of age, kidney qi becomes withered and scorched, and the liver, heart, spleen, and lung — the four viscera — along with all the channels become empty. By one hundred years of age, the five viscera are all vacuous, spirit-qi has departed, and only the physical frame remains alone before the end comes.
The Yellow Emperor asked: Those who die before reaching their natural lifespan — what is the reason? Qi Bo said: Their five viscera are not firm and secure, the philtrum groove is short, the nostrils flare outward, breathing is rapid and violent, the facial bones are low and thin, the vessels are weak and blood is scant, the muscles are not solid, and they are repeatedly subjected to wind and cold invasion. Blood and qi are weak, the pathways of the vessels are not unobstructed, and upright qi and pathogenic qi attack each other, causing qi dynamics to become chaotic and pull against one another — therefore they die in mid-life.
This chapter focuses on "Natural Lifespan" (tiān nián) — the natural human lifespan and its patterns of flourishing and decline. The core thought can be summarized in three points:
Life is founded on parental essence and blood, with Spirit as the sovereign
Ancient thought held that human life is built upon the mother's blood as the material foundation and the father's essence as the protective function; their union forms the physical body. But physical form alone is not enough — there must be "Spirit" (shén), encompassing harmonized blood and qi, unobstructed Nutritive and Defensive qi, spirit-qi residing in the heart, and the completion of both souls (hún and pò) — only then does one become a true person. "Losing Spirit brings death; obtaining Spirit brings life" regards Spirit as the marker of life and death.
Longevity or early death depends on innate endowment and the state of the viscera and qi
Those who live long have firm and secure five viscera, harmonious blood and vessels, supple muscles, dense skin, normal Nutritive and Defensive circulation, fine and slow breathing, six bowels that digest food, and fluids that are spread properly. Those who cannot complete their natural lifespan have insecure five viscera, thin vessels with scant blood, insubstantial muscles, repeated invasion by wind and cold, and conflict between upright and pathogenic qi. This embodies the traditional Chinese medical view of "unity of form and spirit" and "internal-external correspondence" in assessing longevity.
Life proceeds in ten-year stages, following a rhythm from flourishing to decline
From ten to forty years of age is the period of gradual充盈. After forty, decline proceeds sequentially through the liver → heart → spleen → lung → kidney, ultimately culminating in emptiness of all five viscera, departure of spirit-qi, and the corporeal frame standing alone. This description links the aging process to changes in the five viscera, forming an ancient model of the life cycle.
General trajectory of the life cycle: The rise in function from ten to forty years of age with decline beginning after forty largely corresponds to what modern physiology describes as the growth-development–plateau–aging process. Human organ function peaks in young adulthood and gradually declines after middle age — a verifiable universal pattern.
"Spirit" and life status: The saying "obtaining Spirit brings life; losing Spirit brings death" bears similarity to the modern emphasis on consciousness, vital signs, and overall functional integrity. Modern medicine also evaluates life status by emphasizing清醒的意识, stable respiration and circulation, and coordinated functioning of organ systems.
The order of visceral decline: The sequential decline of liver, heart, spleen, lung, and kidney is a model constructed by ancient Five-Phase (wǔ xíng) theory, not a precise correspondence to organs as understood in modern anatomy. "Liver qi declines at fifty" should not be directly equated with modern liver disease or declining liver function indices. The value of this model lies in offering a holistic framework for observing aging, not in precise prediction.
Facial features and longevity: The references to "deep and long philtrum," "high and square facial foundation," and "flaring nostrils" belong to ancient diagnostic observation (wàng zhěn) experience. Modern scientific evidence is limited, and these should not be used as criteria for predicting lifespan. They can be viewed as ancient empirical generalizations about innate endowment and constitution.
Adjust activity intensity according to age: This chapter describes "at ten, love to run; at twenty, love to walk briskly; at thirty, love to walk leisurely; at forty, love to sit," suggesting that activity patterns and intensity should be adjusted according to the flourishing and decline of qi and blood at different ages. Young people may be more active; after middle age, moderate and steady activity is appropriate.
Maintain harmonious qi and blood with dense interstitial spaces: In daily life, maintain regular daily routines, avoid repeated exposure to wind and cold, engage in moderate exercise to promote qi and blood circulation, and eat temperately to nourish the spleen and stomach and replenish fluids. These are general principles of life maintenance.
Value the stability of Spirit: The text emphasizes that obtaining Spirit brings life, indicating the importance of emotional equanimity and inner mental focus for health. Avoiding excessive emotional fluctuations such as worry, sorrow, and anger in daily life helps maintain smooth qi dynamics.
Do not pursue arts of immortality: This chapter describes the natural laws of life; it does not teach methods for achieving immortality. One should rationally view birth, aging, illness, and death, focusing instead on enhancing the quality of life at every stage.
