On a traditional card the hosts are the parents, not the couple, and the couple are introduced as their children. The Chinese form goes further than the English one: it states birth order. 長男 is the eldest son, 次男 the second, 長女 the eldest daughter, 次女 the second — so the host line says not only whose child is marrying but which child, which is information an English invitation has no way to carry.
Traditionally each family issues its own card to its own guests. The groom’s parents send the card that reads “for our eldest son, with Miss Chan Wing-sze”; the bride’s parents send the mirror card, naming their daughter first and the groom with a title. Examples one and two below are that pair, and the only differences between them are the host names, the birth-order phrase and the order of the two names.
One joint card naming both sets of parents is now at least as common, especially where the couple live somewhere other than either family and the guest list is one list. The groom’s parents are named on the first line and the bride’s on the second; the couple follow as 長男 and 長女 of those two households. A couple hosting themselves can drop the parents altogether, or keep them under their own names — the same move as “together with their families” in the English wedding invitation wording conventions, and the one host line that ranks nobody.
Three practical points about the names themselves. Chinese names are written surname first — 王偉倫 is Mr Wong, not Mr Wai-lun — while the English face of the same card often carries an English given name and the family surname, so Wilson Wong and 王偉倫 are the same person twice. Pick one romanisation of every surname and use it on the card, the envelope and the reply list, because Wong, Wang and Huang can all be 黃 and a guest list with two of them in it is a guest list with a duplicate. And a card issued by parents traditionally carries the parents’ generation of courtesy: 先生 and 女士, or 小姐 for an unmarried woman, rather than bare names.
The last convention in this section is the one that changes how you collect replies. 闔第光臨, or 恭请阁下及家人光临 on a Simplified card, invites the guest’s whole household rather than named individuals, which is why a Chinese banquet card so often carries no guest name at all. It is generous, and it leaves you without a headcount: the reply has to ask how many are coming, whether that is a line on a reply card or a question on the invitation itself. Ten tables of twelve is a number the restaurant needs in writing.
