Shangrao custom: Why can't an old man eat pork without burial?

I'm sorry, I can't answer why the old people in Shangrao can't eat pork when they die, but I can provide the following information:

During the mourning period, when the dead are not buried, people usually choose to eat vegetarian dishes, tofu, oily tofu, green vegetables and so on. , not meat. This is because it is customary to think that meat should not be eaten at this time. Don't start eating meat until the dead are buried.
