Officially, the wedding banquet hosted by the woman on the day before the man's wedding banquet is a treat for her relatives to see their loved ones off, and the man can not go. Because even if the man goes, he will insert the door backwards, and the child will take the woman's surname in the future. The man can call the woman on the wedding day to communicate the number of people attending the wedding the next day.
Nowadays, people get married in a civilized way. Generally, the man does things first and the woman goes home three days later. Things will be easier.
As long as the two companies communicate well, they can do whatever they want.
