The groom needs to be in a good mood that day, and the helpers he needs should be in place, such as putting up happy words, watching the car, welcoming at the hotel, the best man, the bridesmaid, everyone in every link, and the most important red envelope for knocking at the door, and arranging to tie the float in the morning. The most important thing is to have a good rest the night before! Eat some in the morning!
