What does divination mean to get married?

In the old society, the marriage procedure was very complicated. Everything should be done according to the wedding customs in the street. When young men and women get married, the parents of the man first ask the matchmaker to propose marriage to the woman's house, and the matchmaker will go to the woman's house to explain the man's financial situation, the groom's appearance, body shape and occupation. Hearing this, the woman's parents initially promised the matchmaker to propose marriage, which is called "spit words" in the wedding market. After being arranged by the matchmaker, the man's family should prepare a gift, and the matchmaker will take the gift to the woman's family and ask for the bride's birthday, which is the so-called "wedding invitation" between men and women.
