It is a traditional marriage custom. A ceremony symbolizing the union of husband and wife. When a husband and wife get married, they take a hair from each head and make a knot together. Both men and women become husband and wife.
Tie: Tie your hair. You must do it when you are an adult. It means when you are young. A young couple. It refers to the original couple, so the second marriage is not considered as a married couple.
One of the origins of married couples is the traditional folk custom of "married couples" in southern Zhejiang, which includes "tying hair to support the body" and "throwing silk to comfort the feelings". The so-called "hair binding and body supporting" means that when the original couple chooses to marry, the man will send Geng Tie and the woman will return Geng Tie. Geng posted his name, date of birth and time of marriage. When the woman returned the Geng Tie, she attached a bunch of hair tied with a red head rope, which was used as a token of love and commitment to each other, to show that the knot of hair is one heart and a good marriage for a hundred years. While "throwing silk to comfort" is the husband and wife with hair tied. When the man drowned and died, and the body was found helpless, the wife had to cut off a bunch of hair, tie it to a stone, and throw it into the accident place to comfort the hair tied. The custom of getting married is said to have been left by an ancient emperor when he ascended the throne.
Second, the origin of married couples. In ancient China, when getting married, the groom took the bride home and held a wedding ceremony. They had to pay homage to heaven and earth, pay homage to the hall, and then the couple paid homage to each other. Finally, they drank Hekan wine, also known as Jiaobei wine. Later, it developed into a ceremony of closing the temples, that is, the couple sat side by side and tied their heads together, hence the term "married couple".
