Have you ever used Ziweixing ultra-long electromagnetic wave physiotherapy instrument?

It certainly works, but it's not as magical as advertised. Many diseases of the elderly have a lot to do with using the brain, and also have a lot to do with using the brain in treatment. So I suggest you buy one for your father, and make sure that the function of this physiotherapy instrument is magical, so that your father can believe that it will be 100% effective for his illness. In fact, it is equivalent to physical therapy combined with psychotherapy, and the natural effect will be good. It's good that your father is happy. And the price is not too expensive, less than 1000 yuan. Buy it.
