I have witnessed that 4th stage lund cancer could be cured with zhongyi.
Several months ago, I had my friend get involved to save a 4th stage lung cancer wang2you2. Within two months, the wangyou's situation was dramaticly improved from near death. There were three and half "wei1xin4" winesses beside the patient and my friend. We expected the patient could go out to walk soon... We all shocked. The following is weixin from my friend recently:
