Let the wedding company make a wishing tree, let each guest write a blessing and hang it on it, and draw a lottery during the wedding.
The wedding company can set up a "Avenue of Stars", which can be placed in the center of the wedding venue. During the wedding, the groom can lead the bride onto the stage from one end of the Avenue of Stars.
If you love singing, you can play a song together on the spot, such as "Crystal" and "Appointment". Singing can be put in the second half of the wedding, or even put on by lovers. It should be very warm and atmospheric.
One small detail: You must meet the MC in advance and spend at least half an hour to an hour to tell him your ideas and designs. Don't choose other non-mainstream emcees, because you are the protagonists.
