I simply checked the information, and it seems that there is nothing very special, so my personal feeling is that this etiquette is a process added by the wedding company itself, in order to create a scene where everyone is crying, make the wedding look touching and advertise for themselves.

The role of father in life is always unclear and vague. Perhaps many people think that such a grand ceremony definitely needs a father, which is very reasonable. In fact, I personally feel that some dads refuse! Marrying a daughter is really not a happy thing. I personally gave my daughter to another person. If she is unhappy in the future, how uncomfortable it will be as a father. ?

For the son-in-law, it is also a kind of entrustment for the father-in-law to give his daughter to himself. He will take care of the girl in the future, but basically no one can do it! So what if you get married! In the end, not everyone broke up in discord. There are many such examples. I don't need to get married. If I really want to get married, I don't want to disturb too many people. If I am unhappy in the future, I will not disappoint the wishes of so many people, and there will be pressure.

This ceremonial handover is only the result of commercialization, just like the wedding now. The core is not blessing, but showing off wealth to see whose wedding is more grand. As for the handover of etiquette, it is only an irrelevant link.

In short, this sense of ritual has no source, but is derived from creating an atmosphere that everyone feels.
