Engagement is also possible, but not necessary.
The delivery date depends on the actual situation, I mean the family. Some gave 1000 1 yuan, which means one in a million, and some gave 4,800 yuan, which was foolproof. There are more, but they are all auspicious numbers. On the day of delivery, the man should bring noodles (probably for pancakes), money, and some red autumn clothes and trousers (for women) and belts. It seems that he doesn't have them now. Old habits.
The lady invited her date to dinner. Nothing else. The rest is to look at two houses and pay attention to something.
