A wedding coordinator is a person who provides advice and guidance to new couples. The purpose is to complete the wedding, help the couple to relieve stress and deal with some trivial matters at the wedding, just like a private nanny who provides overall planning.

Wedding is a religious ceremony or a legal notarization ceremony. Its significance lies in gaining social recognition and blessing, preventing bigamy, helping newlyweds adapt to new social roles and requirements, and preparing to assume social responsibilities.
