How much do you know about the eight-character marriage that has been circulated since ancient times?

The ancients attached great importance to marriage. It is reported that in some areas, after the matchmaker proposes marriage, the man will ask the woman's birthday (commonly known as Geng Tie, usually written in red paper). After a man gets a woman's birthday, he will put it on the man's stove for three days. See what will happen at home in these three days. If everything goes well at home during this period, it means that the woman will bring good luck to the family. The way of marriage mentioned above is a folk custom, and it is the first thing that people should do before making an appointment to get married.
