In order to further study the mechanism of cupping therapy, he visited famous doctors all over the country, and explored the therapeutic mechanism while learning cupping therapy. Through continuous study, research and practice, he found that the internal organs, limbs, meridians, nerves and blood of the human body have corresponding reflex zones on the back of the human body, and cupping in the reflex zone can not only treat diseases, but also diagnose diseases.
After knocking and cupping at Shu point on the back, marks of different colors and shapes will be produced. Through a lot of clinical practice, the relationship between the color and shape of cupping marks and visceral diseases was explored. This simple discovery laid the foundation for the later invention of "cupping diagnosis at Yuquan point on the back".
After more than 20 years of hard study and repeated experiments, Mr. Li Yuquan has accumulated more than 300,000 clinical cases, which were secretly passed down by Professor Li Zhinan, a famous national health expert. On the basis of many years' clinical experience, according to the meridian theory, zang-fu theory and yin-yang and five elements theory of traditional Chinese medicine, we have created a "Yuquan multifunctional cupping diagnosis and treatment instrument" and written "Yuquan cupping diagnosis and back acupoint diagnosis" and "Yuquan cupping clinical meridian holographic therapy"
