In ancient times, Nacai asked what the name meant.

In ancient times, the marriage process was called "Six Rites", which refers to six steps: receiving gifts, asking names, accepting gifts, inviting guests and welcoming them. The so-called "receiving gifts" means that the man invites the matchmaker to propose marriage to the woman's house. According to the ancient ceremony, before the man receives the gift, he will invite the matchmaker to the woman's house to explore the news, and the woman's house will agree to receive the gift. After "accepting talents", there is "asking the name", that is, the matchmaker asks the woman's name, age and constellation, and tells fortune through divination to see whether the men and women will meet each other and whether there are other places that are not suitable for marriage. "Asking the name" is also called "Guo Xiao Tie" or "Guo Ba Zi".
