Patting the stomach can promote intestinal peristalsis, avoid constipation and reduce tummy. Just lie flat on the bed or sofa every day, bend your feet and relax. Put your fingers together and bend your fingers slightly, so that your palm sinks into the bowl. Aim the sunken part of the palm at the navel, and then take turns to replace the slapping with the left and right hands. Pay attention to mastering the slapping strength and don't feel obvious pain when slapping. It will have an impact in the long run.
