It is only a custom in some regions that when marrying a daughter, it is not allowed to post double happiness. This is because in some regions, when marrying a daughter, it is customary to post single happiness, while when marrying a son, it is customary to post double happiness. This way, outsiders can easily distinguish whether they are marrying a daughter or a son, making it easier to identify. At the same time, there is also a saying that when marrying a daughter, the daughter has to leave the family, which means that there is one less person in the family, so a single word of happiness should be posted. When a son marries a wife, he needs to bring in one person to the family, and the number of family members will also increase, so double happiness should be posted.
