According to my memory, traditional Chinese weddings rarely had young children present.
Even if there were children there, they would be together in a separate location apart from the adults who were active participants in the ceremonies.
Granted, things are probably different now in year 2022. But children having a children's space apart from the adults' space for occasions meant for adults has very much been a thing in traditional Chinese culture.
I remember how horrified I was, at the first dinner my husband and I had as husband and wife with his parents and two sisters, when his sisters' kids insisted on sitting not only with us but also in between us, the newly wed couple. Because of how I was raised, where I was from that would have earned those kids a serious scolding for having the nerve to even suggest something so outrageous, because they didn't know their place and were being completely rude to intrude upon the just married couple. And I felt so disrespected when their mothers insisted that I should let their kids sit in between their uncle and new aunt, that they were just kids trying to be sweet.
My family would have had a children's table for them so they did not "bother" the adults who were celebrating a major milestone for a daughter of the family. I told the story to my grandparents, and they were epically pissed. They made sure to let my husband know that I had been treated poorly by my new in-laws as a new member of their family all right.
