Because they have financial strength, they can certainly make the wedding bigger and more ostentatious. We are looking at the Northern Song Dynasty at that time, and I think it is the same. Few people will be willing to punch their faces and pretend to be fat. If ostentation and extravagance, mainly depends on the economic strength of the people of the Song Dynasty at that time.
Therefore, from the background of the times, if families with similar economic conditions, in fact, the Northern Song Dynasty should be similar to ours today, because after all, marriage is a more important thing in the hearts of people in the Northern Song Dynasty and modern people.
It's hard to compare ostentation and extravagance, but judging from the complexity of the wedding. Ancient times were more or less complicated than now. Although today's wedding is still a very important occasion, there are few occasions where the first thing to do is to exchange Geng cards as in ancient times, and there are many customs involved.
Although in today's society, every place has its own customs, but it is not that complicated. For example, there are a series of professional terms and behaviors such as "making false accounts", "making a fortune" and "holding towels" in weddings in the Northern Song Dynasty.
Although such behavior will happen more or less in society, it is not as strict and professional as in ancient times. Anyway, on the whole, these ancient behaviors were to bless the newlyweds and then seek a good omen, which also shows that people in any era attach importance to marriage and are serious.
