I can improve my daily habits, quit smoking and drinking, tonics and so on. I can start practicing qigong, so can my father. He used to have stomach trouble, but now he is in good health and doesn't even feel like an old man. There is also a daily diet to pay attention to, can not eat irritating food, and finally eat appetizers for health.
This one. . . If you can't quit, drink less and never drink too much. My dad just drinks a small glass of fitness. You don't have to practice Tai Chi Qigong or anything, and you can go out running and skipping in the morning.
