What do you mean married couples get married?

Among married couples, "married" means to tie your hair, that is, when you are young. In ancient times, Han men and women had to wear long hair, and when they reached a certain age, they were held "adult ceremony" for them. Put your hair in a bun, which is called a knot, and then put on your hat. So, married couples mean: couples formed when they were young. Refers to the original couple. The word "married couple" comes from the third of Wu's four poems: "Married couples have no doubt about love."
