Can my aunt's married nephew handle it?

Aunt married nephew can carry the light.

Customs vary from place to place. Generally speaking, in the north, if the aunt gets married, the groom or the younger generation can carry a lamp and ask for a red envelope, which means that the nephew married by the aunt can carry a lamp.

Nephew is basically interpreted as the son of a brother or other male relative of the same age. Also known as a friend's son, it is a polite expression.
