1. Foot reflex area health method-principle of nerve reflex
　　Neural reflex is a response of the human body to external stimuli. When abnormal phenomena occur in human tissues and organs, there will be bubbles, sand grains, grains, latches and small nodules in the reflex area corresponding to the foot. When massaging these reflex areas, there will be a very obvious tenderness. This pain will be transmitted to the central nervous system along the afferent nerve, and then regulated by the central nervous system and send out new nerve impulses, which will lead to a series of neurohumoral regulatory responses, stimulate human potential and adjust the imbalance in the body.

　　2. Traditional Medicine-Principle of Bioholography
　　Holographic theory is a science developed in modern times. The theory of holography is actually about the relationship between the whole and the part. When we cut the branches of a complete plant and insert them into the soil, it will grow a new individual that is exactly the same as the original plant. As a whole, every organ of the human body with independent functions contains the whole information and images of human beings. There are many organs with independent functions in the human body. Why do we attach such importance to this part of the foot? The foot reflex massage mentioned here does not exclude other local massage, but foot massage has more advantages than other local massage. This is the advantage of holographic theory: human foot is larger than other organs such as hands, ears, nose, lips and so on. It contains more information about human body, and foot muscles. Relatively thick flesh, dense capillaries, rich nerve endings, complex structure, far from the heart, is the weakest part of blood circulation, so foot massage is superior to other organs, which is the best choice.

　　3. Meridian Science-Principle of Meridian in Traditional Chinese Medicine
　　Meridian theory is the main theoretical basis of traditional Chinese medicine and an important part of traditional Chinese medicine. Five thousand years ago, the Internal Classic of the Yellow Emperor of China recorded the document Guantoi Paper, which is about foot massage that can make people healthy. Meridians are a "channel", and people who are blocked will feel uncomfortable. Meridian traveling line is connected by acupoints in different parts of human body. There are many acupoints on our feet. When we massage the reflex area of foot, these acupoints will be stimulated. Like the principle of blood circulation and reflex, it conducts along the meridian traveling line, thus playing the role of dredging meridians and collaterals. Traditional Chinese medicine believes that "pain is not". This is the reason why massage foot reflex area can play the role of dredging channels and collaterals.
