I understand your situation (although I'm a guy). I am lucky that this didn't happen to me when I was getting married (instead, my mother-in-law only took small part of the given ping kam as hou yi tou)

Maybe I'm biased, and I'm on your hubby family side.. or rather I don't really like Chinese tradition and the social norm - they REALLY like to compare (everything, from the location, amount of ping kam, wedding photographer yada yada). I think that couples should just spend what they can afford rather than overspending just to prove that the husband is not stingy.

Parents sometimes have to understand that they demand a lot of money from their future son-in-law, but end up both daughter and son-in-law suffering

Anyway... I suggest the following:

- Try talking to your parents (yes, unluckily it IS your responsibility since they are your parents), explaining that both of you have already spent a lot and why at this moment it isn't feasible to give 6k. Do not say provoking statements like "It's not selling daughter" though

- Try to propose something that you and your hubby can afford. Maybe something like 2888 or 3888

- To be frank, 6k isn't that much. But as you're both short of cash, maybe ask your parents if your hubby can pay that 6k some time later instead of now. Otherwise, go for Personal Loan

I hope it helps, and I wish you all the best

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!!!
