Does it matter if there is only one lantern left?

Since there is only one, take it off directly, or buy another one and hang it up. It's like shoes. There can't be one big and one small, and there is no right on the left. Lantern as a symbol of incense lamp is not unreasonable. In some places, a lamp or lantern will be hung in the ancestral hall. Besides, this matter can't be delayed to avoid accidents.
