What harm can it do to bury a person's age underground?

What harm can it do to bury a person's age underground? Although it is superstitious and unreliable from a scientific point of view, it is taboo in China, so it is best not to. I have read a horror novel before, which is exactly the same as what you said. In the novel, this is a kind of living sacrifice, which is to make this person's soul become a road god to protect this road, similar to repairing bridges and piling. Legend has it that burying the soul and birthday of the living in a jar at the crossroads will kill you. So try not to bury people's ages and birthdays in the soil.
