He is not as exaggerated as in the martial arts novels, but magic does exist. According to Master Hui Hengwei, a marrow friend who focuses on the teaching of Yijinjing, Yijinjing is a method that can completely transform the body. If you practice regularly, your bones and muscles will change, especially in terms of strength. Because your muscles are thick and your bones are strong, your qi and blood will be smooth, and you will become particularly powerful, that is, full of energy. Correspondingly, unhealthy factors related to blood, bones and muscles such as lumbar spondylosis, cardiovascular and cerebrovascular diseases will also be improved. This is a traditional fitness technique that is dozens of times more than running and yoga.
