What do you mean "X Mansion is used for banquets"?

In the wedding reception custom in Guangdong,

If a man and a woman have a family dinner, it is called: (man's surname) (woman's surname) joint marriage;

If the man's family holds a banquet alone, it is called: (the man's surname) the house welcomes the bride;

If the woman's family holds a banquet alone, it is called: (woman's surname) the official government returns the gift.

I think it's the woman's back door banquet.
