The photo album should be played before the wedding and when the guests enter the venue, so that friends who arrive at the venue in advance will not feel bored and will not feel that the waiting time is too long. Will be used as a warm-up to let the wedding play some cheerful, warm and romantic songs. The opening animation is played before the host's appearance, that is, before the official start of the ceremony, for the purpose of opening, and played after the host's appearance; I don't know how your MC arranged for you to play. Usually, the groom will appear first and then marry the bride. With the wedding March, the couple will be led out by the host and perform an emotional journey after the stage stops. At this time, everyone will watch your video, and then continue the following link. As for sand painting, I don't know what you are doing. If you are grateful to your parents, you can use it to guide them to appear. If you are also describing how you love each other, I suggest following your feelings. After the ceremony, relatives and friends should try not to put photos when eating, because first of all, no one will watch, and secondly, the wedding will be cancelled.
