"Dust" is homophonic with "Chen", so "sweeping dust" means "getting rid of the old"). In old Europe, Christmas Eve was also a day to clean the dust. This day, especially for parents in rural areas, is a very hard day. They have to do a lot of things for Christmas and New Year: they are busy working in the fields, taking care of animals, cleaning the floor, cleaning kitchen utensils, baking Christmas geese, making cakes, arranging Christmas trees, and placing Christmas presents ... When the whole family gets together to celebrate Christmas Eve, parents are usually too tired to help themselves.
The custom of Christmas Eve gradually spread to China, and the day before Christmas was called Christmas Eve. Before Christmas Eve, a kind of gift called "Ping An Fruit" began to pass quietly in people's hands.
