When the Yellow Emperor was studying Taoism in Kongtong Mountain, he met many people who went to Guangchengzi to seek advice and discuss Taoism, and there were some knowledgeable and flexible erudites among them. Among them was a high-powered man from the Yandi tribe, who was a great figure and was called "Qi Bo".

Qi Bo was originally a famous pharmacist of the Yandi tribe, he once traveled all over Shenzhou to find herbs and collect herbs like his ancestor Shennong, and he had already become a medical expert proficient in medicine by treating people for many years. He also invented the five elements through the body's internal organs and meridians.

When the Yellow Emperor first met Qi Bo, Qi Bo was following his master "Zhongnanzi" to meet the Yellow Emperor's master Guangchengzi. At that time, the Yellow Emperor did not know Qi Bo, but at that time, Qi Bo's medical attainments were already very deep.

Zhongnanzi is also a person with a deep Taoism, and he is a friend of Guangchengzi. Zhongnanzi saw that the Yellow Emperor was open-minded and studious, and he liked to make friends, so he recommended Qi Bo to the Yellow Emperor. The Yellow Emperor saw that Qi Bo was a skilled doctor and an upright person, so he happily associated with him.

Once, the Yellow Emperor went to visit Qi Bo in the Yandi tribe, and Qi Bo entertained him very warmly. The Yellow Emperor saw that Qi Bo was very hospitable, and his views in all aspects were also very unique. Especially when it comes to medicine, Qi Bo knows a lot and widely, and he answers every question.

The Yellow Emperor saw that Qi Bo knew everything in medicine, and he thought he had met a confidant. So the Yellow Emperor was there to talk to him about medicine and politics, and Qi Bojun answered freely and insightfully.

The Yellow Emperor felt that Qi Bo was a rare talent with erudition and good upbringing, so he got close to him by talking to him many times. Qi Bo did not deliberately curry favor with him because of his identity as the Yellow Emperor, but always insisted on the truth on some issues.

The Yellow Emperor admired such a talent very much, so he invited Qi Bo to be his teacher and minister in charge of medicine. After a period of investigation, the Yellow Emperor saw that Qi Bo was really a superb doctor, so he let him focus on medicine, and let him treat the people while prescribing his own medicine, Qi Bo did a good job in all aspects.

The Yellow Emperor was also infected by Qi Bo's interest, and liked to talk about medicine and Taoism, and often discussed medical Taoism with Qi Bo.

In the past few years, the Yellow Emperor and Qi Bo have communicated in the form of questions and answers. Qi Bo answered a total of 1,08 questions raised by the Yellow Emperor, and Qi Bo's answers made the Yellow Emperor convinced every time.

Their conversations covered a wide range of topics: physiology, pathology, pharmacology, diagnostics, principles of treatment, and more. They all discuss specific studies on the treatment of human causes, and these conversations are the most detailed medical knowledge for human body research.

The Q&A between the Yellow Emperor and Qi Bo theoretically established the theory of yin and yang and the five elements, the theory of pulse, the theory of Tibetan elephants, the theory of meridians, the theory of etiology, the method of diagnosis, the method of treatment, the theory of health preservation, the theory of luck and many other theories, which reflected the humanistic thought of the unity of heaven and man that the Chinese nation had established in the Yanhuang era.

Because the Yellow Emperor was a very intelligent and talkative person, he would always ask others for advice whenever he saw something he didn't understand.

Once, the Yellow Emperor asked Qi Bo: "Qi Bo, you see that I am not half a hundred and I am tired and uncomfortable, what is going on?" I heard that people in ancient times could live to be 100 years old, but nowadays people often grow old or even die after just over half a hundred, what is the reason for this? ”

Qi Bo said: "Yellow Emperor, this is because the ancients were able to regulate their health according to the natural law of yin and yang of heaven and earth. Anyone who can live beyond 100 years old can eat in moderation, combine work and rest, have regular work and rest, and have moderation in sexual affairs. Therefore, they can be vigorous and naturally live to the age of 100 years given by God. On the contrary, if you don't pay attention to health preservation, violate the laws of daily life and rest, indulge in wanton desires, and consume yin essence prematurely, such people will die prematurely. ”

The Yellow Emperor said: "Qi Bo, what does the change of the four seasons have to do with the diseases of the human body? ”

Qi Bo said: "Why not? As long as people follow the law of yin and yang changes of the four seasons, they can obey the principle of prosperity and decline of spring birth, summer length, autumn harvest, and winter storage. In this way, people will not suddenly get sick, and they will live a long and healthy life to a hundred years, which is the way of health preservation! ”

The Yellow Emperor said: "What should I do in spring? ”

Qi Bo said: "The three months of spring are the time when life sprouts. At this time, all things in heaven and earth are naturally vibrant and prosperous, and people should get up early and go to bed early. It is also necessary to keep oneself in a happy mood and full of enthusiasm, and to conform to the spring qi with all things to protect the liver from damage. ”

"What about the summer?" The Yellow Emperor asked again.

Qi Bo said: "The three months of summer are the solar terms when all things in nature are flourishing and vigorous. At this time, the weather falls, the ground rises, and the plants bloom and grow vigorously. People should go to bed late and wake up early, and they should keep themselves energized. In order to keep the flow of qi and blood, so as not to damage the heart. ”

"What about autumn?" The Yellow Emperor asked again.

Qi Bo said: "In the three months of autumn, nature is converged by the maturity of all things. At this time, the sky is high and the wind is urgent, and the earth qi is gone, so people should go to bed early and get up early. At the same time, it is also necessary to calm the qi and calm the nerves, and converge the influence of the killing qi on the human body, so as to maintain the function of the lung qi to clear the body. ”

The Yellow Emperor finally asked, "What about winter?" ”

Qi Bo said: "The three months of winter are the season when everything is dormant and hidden, at this time, the water is cold and frozen, and the earth is cracked. People should go to bed early and wake up late. To keep the yang energy hidden inside and not leak out, we must know how to avoid the cold and keep warm. In order to maintain the sanity and maintain the closed qi, so that the kidneys can provide sufficient growth conditions for the spring students. The above are the health conditions for the human body at four o'clock. Because by obeying the growth and decline of yin and yang, people can survive, and if they disobey it, they will die. ”

When the Yellow Emperor heard this, he finally understood some truths. He said, "Qi Bo, you mean: between heaven and earth, within the six combinations, including the nine orifices, five internal organs, and twelve joints of human beings, are all connected with the weather. The weather derives the five elements, and the yin and yang qi are divided into three according to the rise and fall of the qi. If the law of change of the five elements of yin and yang is often violated, then the evil qi will harm the human body. Therefore, adaptation to this law is fundamental to the continuation of lifespan. ”

Qi Bo said: "What the Yellow Emperor said is extremely true, because climate is the foundation of life, it is nothing more than the yin and yang of the sky. The yang energy of the human body is as important as the sun in the sky. If Yang Qi is lost, the vital functions will be weakened and insufficient, and the person's life will be reduced or he will die young. In addition, cold, heat, dampness, dryness, wind, and evil can all cause the disorder of yang qi, which can lead to the obstruction of the nine orifices, muscle congestion, slackening of guard qi, exhaustion of yin, yang and yin deficiency, blood stasis and qi knots, and obstruction of Yu acupoints, etc., which will lead to the occurrence of various diseases. ”

The Yellow Emperor asked, "Since Yang Qi is so important to the human body, what will happen to the effect of Yin Qi?" ”

Qi Bo said: "The production of yin qi is also very important to the human body, and the essence of yin mainly comes from the five flavors of food. The five internal organs in our body are the places where the essence of yin is stored, and the five internal organs will be harmed by the five flavors.

If we overeat the sour taste, it will cause the liver qi to overflow and become excessive, which will lead to the failure of the spleen. If you eat too much salty, it will cause bone damage, muscle shortening, and depression; If you eat too much sweetness, it will make your heart full of qi, your qi will be reversed, your face will be blackened, and your kidney qi will be out of balance. If the bitter taste is excessively eaten, it will make the spleen too dry and not moist, thus blocking the stomach qi; If you eat too much spicy, it will corrupt the muscles and veins, cause relaxation, and also damage the spirit.

Therefore, if we carefully reconcile the five flavors, we will make the bones strong, the muscles and veins soft, the qi and blood smooth, and the intestines dense. In this way, the backbone will be strong and not easy to damage. Therefore, if you regulate the five flavors, pay attention to the way of health preservation, and implement it in accordance with the correct health preservation method, you will maintain the vigorous vitality of your talent for a long time. ”

The Yellow Emperor asked, "Qi Bo, I heard that there are eight winds in nature, and there are five winds in human meridian lesions, what is going on?" ”

He replied, "The so-called eight winds of nature are the external pathogenic evil spirits. This evil qi will invade the meridians and cause the meridians to produce wind evil diseases. The wind evil will continue to flow along the meridians, thus invading the five internal organs and causing lesions to occur in the five internal organs.

For the four seasons of the year, there is a mutual relationship with each other. Moreover, Dongfeng was born in spring, and the disease mostly occurred in the liver, and the meridian qi of the liver was infused into the neck. The south wind is born in summer, and the disease mostly occurs in the heart, and the meridian qi of the heart is infused into the chest and flank. The west wind is born in autumn, and the disease mostly occurs in the lungs, and the meridian qi of the lungs is infused into the shoulders and backs. The north wind is born in winter, and the disease mostly occurs in the kidneys, and the meridian qi of the kidneys is infused into the waist and femur. The long summer season and the central orientation belong to the soil, and the disease mostly occurs in the spleen, and the spleen's meridian qi is infused into the ridge.

Therefore, the evil spirit in spring hurts people, and many diseases are in the head; In summer, the evil spirit hurts people, and there are many diseases in the heart; Autumn evil spirit hurts people, and many diseases are in the shoulders and backs; In winter, evil spirits hurt people, and many diseases are in the limbs.

Gynamoma occurs more often in spring, chest and flank diseases occur more often in summer, winter ejaculation and other cold diseases occur in long summer, wind malaria occurs more often in autumn, and paralysis occurs more often in winter. If you do not massage the activities that disturb the yang energy in winter, there will be no diseases of the liver and neck in the spring, no diseases of the chest and flanks in the summer, no internal cold diseases such as diarrhea in the long summer, no wind malaria in the autumn, and no convulsions, diarrhea, excessive sweating and other diseases in the winter.

Jing is the foundation of the human body, so if the essence of yin is hidden and not leaked, there will be no fever in spring. In the summer and summer, if you can't sweat and dissipate heat, it will cause wind malaria in the autumn. This is the general rule of the diagnosis of ordinary people at four o'clock. ”

The Yellow Emperor asked again: "In this way, does the human body also have yin and yang?" ”

Qi Bo replied: "In terms of the yin and yang of the human body, the outside is yang, and the inside is yin. If we divide the parts of the body, the back is yang and the abdomen is yin. If we divide the internal organs into yin and yang, the internal organs belong to yin, the internal organs belong to yang, and the liver, heart, spleen, lungs, and kidneys belong to yin. The gallbladder, stomach, large intestine, small intestine, and bladder are all yang.

In addition, we need to understand the role of the four seasons of yin and yang in the treatment of diseases. For example, winter disease is in yin, summer disease is in yang, spring disease is in yin, and autumn disease is in yang, which should be treated according to the location of the disease.

In addition, the back is yang, the yang in the yang is the heart, and the yin in the yang is the lungs. The abdomen is yin, the yin in yin is the kidney, the yang in yin is the liver, and the yin in yin is the spleen. The above are all examples of the interconnection and correspondence between male and female in the human body, inside and outside, so the yin and yang of man and nature are corresponding. ”

The Yellow Emperor asked again: "Qi Bo, in addition to the five internal organs corresponding to the four times, do they have any similar things that can be summed up?" ”

He replied, "Yes! For example: Oriental cyan, cyan communicates with the liver, the liver is open to the eyes, and the meridian qi is hidden in the liver. When the liver is sick, it is mostly frightened, and it is sour in the five flavors, which is the same as that of plants and trees. It is a chicken in the five crops and wheat in the five grains, and it corresponds to the spring in the four seasons. It is a year star in the celestial body, which indicates the rise of yang energy in spring. Therefore, its qi is in the head, it is in the five tones as the horn, its number is eight, because the liver is the main tendon, and the smell is the face.

The south is red, red and the heart are connected, the heart is open to the ears, and the meridian qi is hidden in the heart. The heart is bitter in the five tastes, the same as the fire, it is the sheep in the five animals, the millet in the five grains, and it corresponds to the summer in the four seasons. It is a glowing star in the celestial body, and the diseases related to it mostly occur in the veins and five organs. It is the emblem in the five tones, its number is seven, and it is coke in the smell.

The central yellow color communicates with the spleen, the spleen is open in the mouth, and the meridian qi is hidden in the spleen. It is sweet in five flavors, and it is the same as the earth. It is cattle in the five animals and millet in the five grains, and it corresponds to the long summer in the four seasons. It is a star in the celestial body, and diseases related to it mostly occur at the base of the tongue and muscles. It is in the palace of five tones, the number of its births is five, and the smell is fragrant.

The west is white, and the white color communicates with the lungs, the lungs open in the nose, and the meridian qi is hidden in the lungs. It is pungent in the five flavors, the same as gold, it is the horse in the five animals, and the rice in the five grains, and it corresponds to the autumn in the four seasons. It is a white star in the celestial body, and diseases related to it mostly occur on the back and fur. It is quotient in five tones, its number is nine, and it is fishy in the smell.

The north is black, the black is the same as the kidney, the kidney is open in the front and back of the two yin, and the meridian qi is hidden in the kidney. It is salty in the five flavors, the same as water, it is the fish in the five animals, the beans in the five grains, and it corresponds to the winter in the four seasons. It is a celestial star in the celestial body, and diseases related to it mostly occur in the knees and bones. It is a feather in five tones, its number is six, and its smell is rotten.

Therefore, a doctor who is good at diagnosing the pulse can carefully and carefully examine the changes in the internal organs and understand the situation of their good and bad conditions. The correspondence and connection between yin and yang, the inside and the outside, and the male and female are clearly summarized, and these profound truths are deeply remembered in the heart. ”

The Yellow Emperor admired Qi Bo's essence and answers, and he also saw Qi Bo's prophetic and moral cultivation from it. Therefore, the Yellow Emperor sincerely respected Qi Bo as his teacher, the "Heavenly Master of Medicine", and made Qi Bo the first generation of imperial physicians in the imperial capital.
