Although life is predetermined, ancient Chinese believes that life can be borrowed like money. When one got an incurable disease, his life was numbered, but if anyone would lend him “longevity”, his life might be prolonged. Therefore, his children or other close relations would fast, perform ablutions and go to ancestral temple to pray, saying they would voluntarily give their own longevity to the sick. But only the voluntary offer rather than the sick person’s asking or begging others could help. If he recovered by chance, people would think gods agreed to lend longevity and burn incense out of gratitude; if he died, those voluntary longevity-lenders would pray again to annul the previous offer for fear that the judge of life might give their longevity to others by mistake.
