now a days, 10k is the norm.
if ur parents in law want to pay only 888,1888 etc, it shows that they do not respect u and ur family.

imagine taking care and giving education to a daughter, that cost much much more, what is 10k?

This is not selling daughter, just a sign of respect from the other family. but off course your future husband must be able to effort la... if no money, better dont get married!!!
