1 \ If the wedding is arranged by the wedding company, don't bother and do something else. Give this question to the wedding company, and their emcee will communicate with the couple in advance. In general, a slightly experienced host should be comfortable with this kind of problem.

For example, when arranging parents' seats, we should be as close as possible to the podium, while the traditional worship of tea is kneeling, and it is reasonable for newcomers to step down and worship tea.
