This is a normal pathological reaction. I have here an excerpt from an interview between host Dangdang and teacher Yang Yi about clapping hands, which is completely consistent with her book. You can refer to it Moderator: Besides reflexology, you admire clapping too much, which is also my favorite. I am particularly lazy and have a special need for health care. Please tell us how to clap your hands in clapping therapy. What are the precautions? Yang Yi: Clap therapy. First, you can't sit and shoot. If you sit and pat, you will pat the tail products of metabolism on your legs, which will be heavier. Be sure to shoot loudly while walking, don't be afraid of pain. After shooting 10 for more than 0 days, my hands are rough and have many burrs. Just spit a crevasse and drain the dirty things inside. Some people have moisture, and people with beriberi can shoot water. People with myocarditis will have a bad heart, and this place will bleed, but don't stop. After stopping, it will be absorbed back, and your suffering will be in vain. Stick to it for an hour after dinner every day, and take about 1000 photos. You can shoot with your hands upside down before shooting, two weeks later, two months or six months later, and even the proportion of your hands has changed. I have a friend who has short fingers and clumsy hands before shooting. After half a year, the shape became longer, the fingers became longer, and even vitiligo shrank. Because the hands are full of internal organs, under the stimulation of slapping, the internal organs are also self-descending. Reflex therapy is to arouse your own immunity, enhance your immune ability, and your body will gradually get better. You said medicine. In the past, drugs were three-point toxic, but now drugs are cultivated with pesticides. I'm afraid it's more than six points poisonous. Moreover, there are differences in clinical individualization, so it is not recommended to take medicine, and you can do it yourself. Yang Yi: You have to shoot while walking. That kind of pain means unhealthy. My hands are very delicate. For example, I am 70 years old, and these hands look thinner than those with hyperlipidemia, and I feel ok. Moderator: Some people say that it was taken according to Teacher Yang's method. After filming, their hands turned black. Is this good or bad? Yang Yi: OK. One of my classmates' hands began to turn black and then gray. What should I do? I said I wanted to get better. Keep shooting. Pat around, circle from the inside out, and shoot all the diseases, that is, severe gastric ulcer, and then shoot. Moderator: It's spring and it's warm outside. After dinner, everyone can clap their hands secretly. Compere: Not all people used to exercise in the morning. Now scientists also advocate that there are more green plants and more carbon dioxide. Exercise is not good at this time, and everyone is encouraged to exercise at night. Well, the way you clap your hands is quite good. Yang Yi: Clap your hands. When you clap your hands, your hands and feet will be incredibly cold, as if frozen in ice. But this cold, with the insistence of clapping your hands, let the cold come out completely. Some people look like popsicles after filming. Gradually, gradually, just film it all. Compere: Will the color of hands change during clapping? Yang Yi: It may be that the color has changed, or the water is coming out and it is chilly. Still have to insist. Moderator: At this time, one is not to be nervous, and the other is to stick to it and observe the color change of your hands. Yang Yi: You can see your change by comparing the photos before and after clapping.
