You can do health exercises: rub your palms, then rub them 30 times from your eyes to your ears and exercise 30 times from your nose to your chin (which can effectively prevent colds); Knock on the teeth 100 times (which can not only tonify the kidney, but also prevent the teeth from falling off), and the saliva produced will be swallowed slowly in three times (which can cure pharyngitis and improve immunity). Rub your knees with your hands and pay attention to spreading your waist. Shake your shoulders 30 times, rub your waist 30 times, expand your chest 100 times (exercise your cardiopulmonary function), and then take a deep breath 10 minutes. Do it once every morning and evening, so that you will be full of energy and not get sick. I'm afraid you can't do it.
