Jewelry money: if the woman is not very demanding, it should be all gold, rings, necklaces and earrings. It should be around 5000. Of course, women will save you money. If you choose a small one, you have to buy diamonds. This will cost more than ten thousand yuan.
Change the fee: the woman changes her name and calls your parents, each at least 1000.
I don't remember anything else.
In fact, if the woman's parents can handle affairs, the engagement money of 10 thousand won't be taken away from you, and will be returned to your girlfriend. This money is still yours. You can't say anything if the woman's parents insist on staying.
