Is it okay to invite people and new people to write invitations like this?

If you invite couples, you can write Mr. and Mrs. XXX (this is a more elegant way of writing) or directly write Mr. and Mrs. XXX, with China male names as the main names.

If the family is invited, write XXX's family, mainly the oldest generation in the family or the person in charge of the family.

Don't scold yourself, it's a joke.
