Western medicine treats diseases, while Chinese medicine treats people. According to the theory of Chinese medicine, people get the whole qi of heaven and earth, but not the partial qi of heaven and earth. You say that this qi can not be seen or touched, you say that the full qi, partial qi how to understand it? As we all know, man is the spirit of all things, no matter how advanced the animal is, it is not comparable to man. On the earth, only man can recognize heaven and earth in turn, animals cannot. “Man is born according to the law of heaven and earth” is mentioned several times in the Yellow Emperor’s Classic of Internal Medicine. Here, I can tell you something. Many students say, “Teacher, teacher, why is this called the middle of the human body?” The teacher says, “Hey, this place is called Renzhong, just remember it.” Actually, it’s not that simple. Think about it, when you are in your mother’s belly, it is the nine orifices and one orifice, the belly button and mother through, mother formed a barrier to protect you. Once you hit the ground, one orifice and nine orifices pass. What are the nerves? It is the channel of communication between human essence and nature’s essence. Then look at the distribution of our nine orifices, the top of which are even numbers and the bottom of which are odd numbers. When a person faints, our elders know to quickly pinch the human middle, because this is where yin and yang meet, once pinched here, the clear yang rises and the cloudy yin falls, which inevitably creates a harmony of yin and yang. This example is to show that man is born from heaven and earth, and man is made by nature. And if you understand how Chinese medicine sees people, you will have a new understanding of the knowledge of health care. I believe that Chinese medicine is based on the ancient Chinese idea of “the unity of heaven and man and the coexistence of heaven and man”, which is the core of Chinese Taoist thought, and uses the theory of the five elements of yin and yang of “Zhou Yi” to study the laws of human movement and life. Strictly speaking, Western medicine treats diseases, while Chinese medicine treats people. In its entire philosophy, TCM requires a person to live healthily and happily during the whole process of birth, growth, strength, aging and death. In this philosophy, heaven and man are united, and there is a natural harmony between the wind, cold, heat, humidity, dryness and fire of nature and the qi and blood in your body under normal circumstances. When you cannot be in harmony with it, you are going to get sick.
