A few years ago, Dr. Zhang's wife had a sudden breast cancer. After trying various treatments, she couldn't stop the spread of cancer cells and eventually spread to all the bones. Seeing his beloved wife suffering from severe pain, Dr. Zhang pondered over how to alleviate her pain. Once, when Dr. Zhang massaged his wife's buttocks, she miraculously eliminated the swelling and pain in her groin. From this, Dr. Zhang realized that any disease in the human body has a fixed origin (deity), and as long as it is handled properly at the origin, the disease (shadow) can be solved. Therefore, based on the spirit of "people-oriented, taking illness as a teacher", Dr. Zhang finally summed up this set of effective "original point therapy" through the practice and classification of tens of thousands of cases.
