The doctor at the time asked me if I knew the specific conditions of my father and grandfather. He sighed and said, "Why don't you go and pray to the Buddha?" At that time, I really felt that after this winter, only half of the family members would be left in the photo. I was crazy and found a special medicine for the new crown for my grandfather within 24 hours. I was willing to pay anything and lose everything else. Later, when my grandfather fell ill, I directly prayed to the Buddha to exchange for his longevity. Maybe this is how the world is. Energy conservation.
