Does it matter if there is only one lantern left?

Since there is only one, just take it away, or buy a new pair and hang it up. This is like shoes. They cannot be one big or one small, left or right. Lanterns are not the symbol of incense lamps. It makes no sense. In some places, a lamp or lantern is hung in the ancestral hall when a baby is born. In addition, this matter cannot be delayed to avoid accidents.
