Who is not good at one or two happy events a year?
Happy events are held twice a year, which is called "Xi Chong Xi" in geomantic omen. That is, the same family has two happy events in a year, then these two happy events will conflict with each other and bring unlucky influence to people. Generally speaking, this kind of influence is aimed at the families of newlyweds and may have an impact on their later lives. Of course, it also has some influence on the guests. After all, you have to pay it twice a year.
If you are very particular about this in local wedding customs, you can discuss staggering the wedding dates of two couples. Generally speaking, it is best to have a year between two happy events. You can choose the way to start and end the new year to stagger the wedding date of two couples. However, from the current social and legal point of view, there is no regulation on the interval of happy events. Even in many areas, there is a saying that double happiness comes at the door, and everyone should decide according to their own attention.
It is taboo for brother and sister to get married in the same year.
If the biological brothers and sisters in the family get married in the same year, there are usually some taboos. If two brothers get married in the same year, many people think that the person who gets married later may hit the person who gets married first, thus affecting a person's fortune. So it is common for brothers to have happy events every year. For brother and sister, there are some different stresses. Most people get married first, and then get married.
Some people in some areas think that if a brother and sister have a happy event in the same year and get married first, then the daughter who gets married later may take away her family's property. If the daughter married first and the son married a new wife, there would be no such worry. In addition, there is generally no need to wait a year, and it is best to hold a happy event every four months.
