由此可见研究交易成本的重要性

专业啊

Take it easy my friend.
Here is what I heard.

The requirement always appears in county.
and the tradition is from past.

In ancient time,
we were all farmers.
Female was a manpower which could be used to grow crops.

When a daughter married,
she used to go away and lived with her husband.
Her ownership transmitted to her husband's family.

You may treat the gift fund as a net value of her future income.
The buyer(male family) has to pay for the creditor(female family).

You may say freedom to love, or something like that.
I agree with you.
Here just sharing my understanding the origin of this tradition.

Other issue,
the owner of the daughter is her parents, not herself.
she couldn't profit from the transaction herself.

Outside county, the tradition will looks funny.
No relevant practice record at all, even in 1930's.
Thank you my friend.

大中华的陈规陋俗啊

观点有些极端啊。。。从反过来看，你愿意相同的钱，能买到其他任意一个想要的嘛？
