MMO Culture has a brief look at the wedding system that just made its way onto the game's Taiwan server. The marriage mechanics include a proposal, some sort of engagement process, a dowry, and a wedding banquet. Apparently there's also an NPC who handles proposals and functions as the Ming Dynasty equivalent of a singles website. It's worth noting that Shaolin players can only propose after they've obtained the Secular Disciple title.
Thus far there's no word on when the marriage system will show up on Age of Wushu's western servers.
