Do I need to calculate the engagement date?

Engagement does not depend on the date. When going through the formalities, the man asked the eloquent people in the clan to go to the woman's house with the man's "Geng Tie" (that is, the man's birthday) to state the details of his family background and future son-in-law. (Match two relatives). If the woman basically agrees, entrust this person, or someone else, with the woman's "Geng Tie" to the man's house to confess. If the man has read the woman's "Geng Tie", he will agree to this marriage. Just let this person say "yes" and then go to the woman's house with an engagement gift, which is considered engagement.

I'll tell you a joke: a matchmaker married two "men". The bride price exchanges between the two sides are constant, and the two sides often entertain matchmakers. There is a saying in the media population that "it is difficult for both sides (men)." When it was time to get married, the sedan chairs of both sides met halfway. When asked about "what's going on", the matchmaker said, "I told you earlier, both sides are men, and you both agreed. Why blame me?"

Earlier, when the two newlyweds didn't meet, it was all up to the matchmaker.
