Chinese medical society believes that the Qi and blood are closely related. Where Qi goes, blood follows. That is why “Qi Xue” (Qi Blood,
If you look carefully, you can see that the elements of your physical body such as the organs, nerves, blood, and even every tiny cell are all like separate machines, each with their own unique function. Just like electric motors, if there is no current in them, they are dead. If you compare the routes of the blood circulatory system, the nervous system, and the lymphatic system with the course of the Qi channels, you will see that there is a great deal of correspondence. This is simply because Qi is the energy needed to keep them all alive and functioning.
Now, let us look at your entire body. Your body is composed of two major parts. The first part is your physical body, and the second is the energy supply which your body needs to function. Your body is like a factory. Inside your body are many organs, which correspond to the machines required to process the raw materials into the finished product. Some of the raw materials brought into a factory are used to create the energy with which other raw materials will be converted into finished goods. The raw materials for your body are food and air, and the finished product is life.
The Qi in your body is analogous to the electric current which the factory power plant obtains from coal or oil. The factory has many wires connecting the power plant to the machines, and other wires connecting telephones, intercoms, and computers. There are also many conveyer belts, elevators, wagons, and trucks to move material from one place to another. It is no different in your body, where there are systems of intestines, blood vessels, complex networks of nerves and Qi channels to facilitate the supply of blood, sensory information and energy to the entire body. However, unlike the digestive, circulatory, and central nervous systems — all of whose supportive vessels can be observed as material structures in the body — Qi channels are non-material and cannot be observed as physical objects. The circulatory, nervous, and Qi systems all possess similar configurations within the body, and are distributed rather equally throughout the body.
In a factory, different machines require different levels of current. It is the same for your organs, which require different levels of Qi. If a machine is supplied with an improper level of power, it will not function normally and may even be damaged. In the same way, your organs, when the Qi level running to them is either too positive or too negative, will be damaged and will degenerate more rapidly. The ancient Chinese character for Qi (

In order for a factory to function smoothly and productively, it will not only need high quality machines, but also a reliable power supply. The same goes for your body. The quality of your organs is largely dependent upon what you inherited from your parents. To maintain your organs in a healthy state and to insure that they function well for a long time, you must have an appropriate Qi supply. If you don’t have it, you will become sick.
Qi is affected by the quality of air you inhale, the kind of food you eat, your lifestyle, and even your emotional make-up and personality. The food and air are like the fuel or power supply, and their quality affects you. Your lifestyle is like the way you run the machine, and your personality is like the management of the factory.
The above discussion clarifies the role that Qi plays in your body. However, it should be noted that the above metaphor is an oversimplification, and that the behavior and function of Qi is much more complex and difficult to handle than the power supply in a factory. You are neither a factory nor a robot, you are a human being with feelings and emotions. Unfortunately, your feelings have a major influence on your Qi circulation. For example, when you pinch yourself, the Qi in that area will be disturbed. This Qi disturbance will be sensed through the nervous system and interpreted by your brain as pain. No machine can do this. Moreover, after you have felt the pain, unlike a machine, you will react either as a result of instinct or conscious thought. Human feelings and thought affect Qi circulation in the body, whereas a machine cannot influence its power supply. In order to understand your Qi, you must use your feelings, rather than just the intellect, to sense its flow and make judgments about it.
Now a few words as to the source of human Qi. As mentioned, Chinese doctors and Qigong practitioners believe that the body contains two general types of Qi. The first type is called Pre-birth Qi or Original Qi (Yuan Qi,
The second type is called Post-birth Qi or “Hou Tian Qi” (
Pre-birth Qi is commonly called “Water Qi” (Shui Qi,

After the Fire Qi and Water Qi mix, this Qi will not only circulate to the Governing Vessel, but will also supply the “Thrusting Vessel” (Chong Mai,
According to its function, Qi can be divided into two major categories. The first is called “Ying Qi” (Managing Qi,
