Casual Discussions of Huangdi Neijing by Dao Yingzi | Episode 001

Hello everyone, I’m Dao Yingzi.
Starting today, we will break down and interpret Huangdi Neijing chapter by chapter. Before we officially begin, I want to share an honest thought with you all. I have no high academic credentials, nor am I an academic expert or medical professor. I am just an ordinary person living among ordinary folks, who spends every day observing and understanding my own body, living a free and leisurely life.
All the interpretations I’m about to share come entirely from my daily reflections and personal physical experiences; they do not represent mainstream annotated versions from books. Nothing in the world is absolutely right or wrong—it all comes down to how you understand and apply it. Throughout this entire series, I will cast aside archaic classical language and obscure professional jargon, and use simple, plain words to talk through the core wellness wisdom left by our ancestors.
The opening volume of Suwen does not start with herbal prescriptions or acupuncture, nor does it list symptoms like headaches and fevers. It only records the fundamental principles for people to live and maintain good health in ancient times. The chapter is called Treatise on the Innate Truth of Antiquity. Simply put, it is practical wisdom passed down by our elders for living a long life. Most people rush to seek medicine when they feel unwell, and hunt for folk remedies once they grow old and fear aging. Yet they ignore that all the secrets to long life are hidden within daily eating, sleeping and mental choices. Every line in the ancient text lays out the rules for humans to coexist with heaven and earth. If you calm down and ponder them, you will understand: whether a person lives a long or short life never relies on external things, but on every single movement and thought of their own.
In ancient times, the laws of heaven and earth operated clearly, and people had simple, pure hearts. Those who understood wellness never abused their bodies. They lived in harmony with the yin and yang of the four seasons: going outside to stretch their bodies in spring, sweating moderately to expel internal turbid energy in summer, calming down to conserve spirit and vitality in autumn, and staying indoors more to protect innate vital essence in winter. This is living in alignment with yin and yang. People would practice simple breathing exercises and stretching movements, without blindly copying others’ wellness routines. They followed the feelings of their own bodies, unifying breath and physique—this is abiding by natural rhythms.
To put it simply, living in tune with yin-yang seasonal shifts and practicing suitable wellness methods essentially means your physical body spirals inward and outward alongside heaven and earth. Externally, you nourish your body following the four seasons; internally, you gather qi and blood to calm your mind. This is what keeps our five internal organs functioning every day.
Diet should suit local land and climate. Each region nurtures its own people, so local ingredients resonate best with the local terrestrial energy. Eat small, frequent meals: eat when hungry, stop once full, and avoid overeating which damages the spleen and stomach. Rest at dusk and rise at dawn—don’t stay up late hurting the liver and gallbladder, and don’t oversleep which stagnates qi and blood all over the body. Do physical work within your limits to avoid straining bones and tendons. Cut down on overthinking, and restrain intimate desires to preserve vital essence without draining yourself recklessly. A stable body and peaceful mind naturally let you live to a hundred years old and pass away peacefully.
In contrast, modern people live in material plenty yet abandon basic wellness principles. Wine has long been classified as medicinal; it is neither inherently good nor bad. Its impact depends entirely on how much you drink and your physical state. Consumed moderately to match your constitution, it nourishes you; drunk excessively alongside unrestrained intimacy, it becomes poison harming your body. The choice lies entirely with your own physical condition. Many treat wine like water and drink heavily every day, even indulging in carnal desires while drunk. Alcohol disturbs qi and blood, and overindulgence drains kidney essence. Combined, these two habits slowly deplete your innate vital energy. People reverse day and night, staying up late for entertainment and taking this abnormal lifestyle as normal.
Chasing fame and fortune all day, craving constant pleasure, tangled in endless chaotic thoughts, joy, anger, sorrow and joy torment your internal organs nonstop. Day after day, you go against your body’s natural laws. Many become weak and sickly with aged faces before turning fifty. Ultimately, they have drained their innate life reserves themselves. Excessive desire and late nights deplete kidney essence, which means the vital energy of your physical body sinks down and solidifies. The more you chase temporary pleasure, the more your internal energy collapses inward, and aging is the tangible manifestation of this sinking vital energy.
Ancient sages saw clearly that humans are vulnerable to harm from external pathogenic influences, so they left us wellness teachings: avoid abnormal weather such as strong winds and sudden extreme temperature shifts, to stop external pathogenic energy from invading your body. Internally, keep a peaceful mind, and let go of obsession over gain, loss, honor and disgrace. When your heart is pure and calm, your internal vital energy circulates smoothly. Stop letting your thoughts drift endlessly outwards; gather them within your five organs. With no pathogenic energy outside and no worries inside, illnesses will hardly find a way to take hold.
Being tranquil and empty-minded is not passive idleness. It means gathering your scattered mental energy back inward, letting your spirit return to its origin, forming a closed loop of internal and external vital energy. Then pathogenic winds cannot invade your body at all.
A calm heart with fewer desires means less anxiety and fear. Moderate physical activity keeps qi and blood flowing smoothly to prevent exhaustion. Do everything within your capacity, find contentment in simple plain food, stop comparing wealth and status, and do not let worldly vanity confuse your mind. Wellness does not demand ascetic deprivation or banning all joy. Daily food, drink and entertainment are all fine—there is only one rule: follow your true inner self, do not torment yourself through internal conflict. Constant overthinking and obsessive rumination may seem harmless in the short term, but over years, mental distress will inevitably break down your physical health.

Mind and body are interdependent. Stagnant emotions wear down the physique, and a weakened body disturbs the mind. Whether sharp-witted or ordinary, anyone who lives steadily in accordance with heaven and earth’s laws will retain intact spirit and vital energy. Even past one hundred years old, they stay nimble and full of vitality. Reducing desire and finding contentment simply cuts unnecessary mental consumption, so energy does not leak outward, and your body forms a self-sustaining internal cycle—this is the simple daily method for long life.
Our ancestors used the numbers seven and eight to explain the shifts in kidney essence strength throughout men and women’s lives.
Women follow cycles of seven: at seven, they shed baby teeth and grow thick hair; at fourteen, their qi and blood flow freely, menstruation arrives and they become fertile; at twenty-one, their physical development fully matures; at twenty-eight, they reach their peak physical condition; at thirty-five, their complexion fades and hair thins gradually; at forty-two, their looks age and grey hair appears; at forty-nine, their qi and blood dry up, menstruation ceases and they enter old age.
Men follow cycles of eight: at eight, they shed baby teeth and grow new hair; at sixteen, their vital essence is abundant enough for them to father children; at twenty-four, their bones and tendons grow strong; at thirty-two, they reach their most robust physical form; at forty, hair loss and kidney deficiency begin; at forty-eight, their complexion dims and grey hair grows; at fifty-six, their legs and feet stiffen and liver energy weakens; at sixty-four, vital essence is exhausted, teeth and hair fall out. The speed at which a person ages hinges entirely on nurturing kidney essence. Nourishing your body in line with the rhythm of kidney essence is the most genuine wellness practice. The seven-eight cycles mark the timeline of vital energy’s ascent and descent in the human body, and the wax and wane of kidney essence sets the pace of your body’s internal and external circulation. Wellness practice is consciously adjusting this circulation speed to slow aging.
Ordinary people always attribute long or short life to destined fate. From the perspective of the Universal Interwoven Force Network, innate physical foundation sets the base value, while your daily thoughts and routine act as the multiplier. Every single thought and movement shifts your internal and external vital energy circulation—lifespan is never fixed.
At this point, many readers will wonder: if men and women age step by step following cycles of seven and eight, is aging inevitable? I hold a different view. This pattern only applies to people who live roughly similar daily schedules and eating habits. As recorded in the Tao Te Ching by our ancient ancestors, the great Dao has no unchanging rigid rules. Any Dao that can be put into words is not the eternal, unchanging Dao.
Your physical foundation is gifted by your parents at birth, yet your later life is entirely reshaped by your own cultivation. Innate factors only set your starting point; your daily routine, mindset and schedule are the key to altering the pace of aging. If you strictly live by the rhythms of spring growth, summer flourishing, autumn harvest and winter storage, and adjust your diet to suit local soil and climate, you can gradually regulate the circulation of kidney essence and slow aging. If you constantly act against natural laws and recklessly drain your mind and body, aging will arrive far earlier.
Therefore, there is no need to fear aging. Innate conditions do not determine your final fate. Abide by seasonal and local natural laws every day, read wellness classics often to calm your mind, maintain a peaceful heart, and correct your bad habits bit by bit. The fixed track of aging can be completely reshaped by yourself.
Finally, ancient people divided wellness and cultivation into four tiers. The highest tier is the True Person of Antiquity: those who guard their original heart and act sincerely. They fully comprehend the great Dao of heaven and earth, absorb the refined vital energy of the universe, fuse their physical body with primordial energy, and possess nearly boundless lifespan. The second tier is the Perfect Person of Middle Antiquity, who holds profound virtue, harmonizes themselves to follow the four seasons, stays far from mortal troubles, and lives far longer than average people. The third tier is the Sage living among ordinary people, who restrains temper and desire, avoids harming their body and spirit over worldly trivialities, and lives steadily to one hundred years old. The lowest tier is the Worthy Person, who imitates heaven and earth’s laws and follows ancient wellness methods. Though unable to transcend life and death, they can slow aging and extend their lifespan.
The four tiers of True Person, Perfect Person, Sage and Worthy Person represent four stages of human energy shifting from sinking down to ascending and transcending. Ordinary people can start with the standards of the Worthy Person, gradually adjust their personal universal force to advance. We do not need to chase the realm of the True Person right away. Simply being a disciplined Worthy Person and steadily regulating your body and mental energy is the greatest value in reading Huangdi Neijing.
