In the past, the process was like this: first, face to face, that is, when men and women meet for the first time, the man should take some money as a sign of sincerity, depending on the wealth of the family, but he should also succeed (this money will be used as a dowry in the future, and of course some women will use it for other purposes). The second is eight characters, which means that both men and women basically have no opinions at this time. The woman can entrust her life to the other party, and the man needs to prepare some bride price. At this time, the man is basically assured that the woman will not change her mind, and the bride price will be more than the first time. The woman will buy clothes and bedding for both men and women and the man's parents. The last step is to get married, which is basically to make two pork elbows, a big fish and a chicken to prepare some dining tables. It's much simpler now. But on the face, you should do it when you should, and it is decent to be generous. That's what people do.
As for the meeting between parents of both men and women, it is nothing special, just like visiting relatives.
