The wedding process will follow the normal steps. Your wife is from Shanghai. You can book him a room in the hotel and then drive to the hotel to meet his new house. Just follow the normal steps until the party is over. The woman doesn't need a welcome. You can rent a wedding dress if you want. If you want to take a photo, call it another photo. But it doesn't have to be as grand as Wenzhou. Shanghai is mainly a feast. Then eat in Shanghai according to the rules of Shanghai. Give a gift if you should, and return the red envelope if you should.
