I am a technician. On September of 1997, I started to practice Falun Dafa. Before that, I had many work-related symptoms such as swelling and congestive eyeballs, dizziness, neurasthenia and strain of lumbar muscles etc. These symptoms had severely influenced my life and work. After I learned Falun Gong, I understand that Qigong can make one become healthy, but the prerequisite is that one must "emphasize his moral value" , "improve his Xinxing (heart/mind quality)", and "become a good person".
