1. In many places, it is the custom of "going to a single place and returning to a double place", that is, the number of men who pick up relatives is generally odd, because after picking up the bride, it is even. The moral here is "adding mouths and adding mouths, pairing up." There are still people who can't be counted as the staff of wedding companies such as cameras and directors.
Most of the married people are unmarried, and the elders in the family can't go if they are divorced, remarried or widowed.
3. Many places have the marriage custom of "menstruation doesn't accept it and menstruation doesn't send it", because "menstruation" is homophonic, "loneliness" and "menstruation" are homophonic and "suspicious" are all unlucky words in marriage.
4. Generally, the best man group and good brothers or relatives are arranged. Neither parent can take part in picking up the bride. Just go directly to the hotel or wait for the couple to come back at home.
5. The staffing of men and women should be basically equal, that is, if the man comes from relatives of the same age, the woman should not arrange relatives of elders.
