Qi has the characteristics of movement, and Qi stimulates and regulates the body's metabolism by its continuous operation, and promotes the life process of the human body.

When the movement of qi ceases and the process of vaporization of the body's metabolism stops, it marks the end of the life process.

The movement of qi is called the qi engine.

The qi of the human body is a very subtle substance with strong vitality in constant motion, which is popular throughout the body, from the internal organs to the five internal organs, and to the muscles, bones, skin, and fur, to exert its physiological functions, and to promote and stimulate various physiological activities of the human body.

The forms of movement of qi vary depending on the type and function of qi, but in general, they can be simply summarized into four basic forms: ascending, descending, exiting, and entering.

The so-called ascending refers to the operation of qi from the bottom up, descending refers to the operation of qi from top to bottom, outward refers to the operation of qi from the inside to the outside, and inward refers to the operation of qi from the outside to the inside.

For example, breathing, exhaling turbid air is out, and inhaling clear air is in.

Exhalation is the upward passage of the lungs through the larynx and nose and excretion from the body, which is both out and up, while inhalation is the downward flow of air through the nose and throat and into the lungs, which is both in and out.

The rise and fall, exit and entry of the body's qi movement are contradictory movements of opposites and unity, which widely exist in the body.

Although from the perspective of the local physiological characteristics of a certain viscera, there is some emphasis, such as the liver and spleen are mainly ascending, and the lungs and stomach are descending, etc., but from the perspective of the physiological activities of the whole body, there must be a coordinated balance between ascending and descending, exiting and entering.

Only in this way can there be the normal movement of the body's qi, and the various organs can play their normal physiological functions.

Therefore, the coordination and balance of the lifting and entering and exiting of the air engine is an important link to ensure the normal progress of life activities.

On the one hand, there must be an unimpeded movement of qi, and on the other hand, there must be a balance and coordination between the rise and fall of qi. With these two points, the movement of qi is normal, and this normal state is called "qi and machine tuning".

The lifting and entering of the air machine is very important for the life activities of the human body.

For example, the innate qi, the water valley qi and the inhaled pure qi must be lifted and lowered before they can be dispersed throughout the body and exert their physiological functions. The essence, blood, and fluid must also flow through the movement of qi in order to continuously flow in the body to nourish the whole body.

The physiological activities of the human organs, meridians, body, and organs must be completed by the movement of qi, and the interconnection and coordination between the viscera, meridians, body, and organs must also be realized through the movement of qi.

In other words, the entire life activity of the human body is inseparable from the movement of qi in and out.

At the same time, the connection and adaptation between man and the natural environment are also inseparable from the movement of qi in and out, such as the inhalation of clear qi and the exhalation of turbid qi, the intake of food and water, and the excretion of feces, urine, sweat, etc.

The movement of qi in and out is the foundation of human life activities, and once the movement of qi in and out is stopped, it also means the termination of life activities.

Therefore, it is said in the ancient Jane: "If you go in and out, the god will be destroyed, and if you rise and fall, you will be lonely."

Therefore, if it is not in and out, there is no way to grow and grow old, and if it is not lifted, there is no way to grow and collect. It is to enter and exit by lifting, and there is no instrument. ”

The viscera, meridians, body, and organs of the human body are all places where qi rises and falls.

The movement of qi in and out can only be embodied in the physiological activities of the viscera, meridians, body, and organs.

The movement law of viscera qi has its own uniqueness, which reflects the characteristics of the physiological activities of viscera and also shows the different trends of visceral qi movement.

According to the five organs, the position of the heart and lungs is at the top, and the upper one should be lowered, the liver and kidney are at the bottom, and the lower one should be raised, and the spleen and stomach are in the middle, connecting the upper and lower, which is the hub of lifting and transferring.

To the six intestines and generalize, the six intestines pass on the substance but do not hide, to use the pass, to reduce to the smooth.

In the process of digestion and absorption of dietary water valley, it also has the effect of absorbing the subtle and fluid of water valley to participate in the metabolism of the whole body.

In terms of the relationship between the viscera, such as the lungs are the main qi, the kidneys are the main qi, the liver is the main ascending, the lungs are mainly suppressed, the spleen is mainly clearing, the stomach is mainly turbidity, and the heart and kidney intersect, etc., all show that the organs and the viscera, and the viscera and the viscera are in a unity of lifting and falling.

In the case of a certain viscera, it is also a unity of ascending and descending, such as the propaganda and suppression of the lungs, the separation of the small intestine and so on.

In short, the lifting movement of the qi machine of the viscera, in the physiological state, embodies the characteristics of rising and falling, descending and rising, rising and falling, and descending and rising, and the law of unity, coordination and balance of opposites.

Due to the smooth movement of the qi of the various organs of the human body, the qi between the organs rises and falls in a coordinated unity of opposites, thus ensuring that the body continuously ingests the substances required for human life activities from nature, and through gasification, it rises and lowers turbidity, ingests subtlety, excretes wastes, maintains the dynamic balance of material metabolism and energy conversion, and jointly completes the metabolism of the whole body and promotes the normal progress of life activities.

When there is an abnormal change in the movement of qi, and there is a loss of coordination and balance between lifting and exiting, it is called "qi machine disorder".

Since the movement of qi is diverse, qi imbalance also has a variety of manifestations.

For example, when the flow of qi is obstructed and not smooth, it is called "qi machine is not smooth"; when it is obstructed and the local blockage is blocked, it is called "qi stagnation"; when qi rises too much or does not fall in time, it is called "qi reversal"; when qi rises too late or falls too late, it is called "qi trapping"; when qi goes out too much and cannot be punctual inside, it is called "qi detachment"; when qi cannot reach outside and is blocked inside, it is called "qi closure".

Understanding the state and mechanism of these movement disorders will be conducive to the establishment of treatment rules for a variety of "qi disorder" lesions.

The various changes that occur due to the movement of qi are called gasification.

For example, the metaplasia and distribution of subtle substances in the body, the mutual transformation between subtle substances, between subtle substances and energy, and the excretion of waste products are all gasification.

In medicine, gasification actually refers to the metabolism of substances and energy such as essence, qi, blood, and fluid caused by the movement of the body's qi, which is one of the most basic characteristics of life, which is different from the concept of gasification in ancient philosophy that refers to the occurrence, development and change of all things in the universe.

In fact, gasification is the process of material metabolism in the body, the process of material transformation and energy transformation.

As the saying goes: "Taste returns to form, form returns to qi, qi returns to essence, essence naturalizes, refined food gas, form eats taste, metamorphosis essence, qi generates form...... refinement into gas" and so on, which is a brief summary of the gasification process.

Therefore, the metabolism of essence, qi, blood and fluid in the body and their mutual conversion are the basic forms of gasification.

For example, the generation of essence includes the abundance of innate essence and the metamorphosis of the essence of the acquired water valley; refinement into qi, including the innate essence of metamorphosis and the acquired essence into the transformation of valley qi, and the differentiation of valley qi into the two qi of camp and health; essence into marrow, marrow and bone filling and consuming or converging the brain and turning into gods; essence and blood homology and mutualization; jin liquid and blood homology and mutualization; blood metaplasia and qi and qi and spirit; jin liquid metaplasia and sweat and urine; qi generation and metabolism, including turning into energy, heat, blood, essence, Transforming the gods into the qi of the viscera and the qi of the meridians, and so on, are all concrete manifestations of gasification.

The excitation and maintenance of the gasification process is inseparable from the function of the viscera.

The orderly progress of the gasification process is the result of the coordination of the physiological activities of the viscera.

The movement of qi is universal, and life activities are produced in the process of continuous movement of qi, so the movement of qi is the root of the process of producing gasification.

The movement of qi in and out and the interaction between the yin and yang of qi are the prerequisites and conditions for the gasification process to occur and be carried out.

Gas is constantly running, and the gasification process is naturally always there.

On the other hand, in the process of gasification, there is the movement of gas in and out, and the various forms of movement of gas are reflected from the gasification process.

The phrase "the life of things is the transformation, and the extremes of things are the changes" highlights that the movement of qi and the gasification process are closely linked.

The movement of qi and the process of gasification maintained by it are eternal, divided into two, united into one, uninterrupted, and present throughout the life process.

The movement of qi in and out maintains the coordination and stability of metabolism in the body and the orderly development of life processes, and the movement of qi and the cessation of its vaporization process means the end of life activities.

Qi has a very important role in the human body, it is not only one of the basic substances that constitute the human body, but also the driving force to promote and regulate the functional activities of the viscera.
