It depends on how long it took your elder sister-in-law to give you 1000. You can get a rough figure by comparing the market at that time with some current market prices, but I think you should get 1000 at least, because most waters should give you even numbers if you get married. After all, it's better to send a pine tree between relatives when they get married. Well, it's ok. If you think12,000 is too much, you can also send10,800, so it depends on how long you have been born. Your aunt followed10,000, so my money now is still different from mine. In the next year, either you can charge less, because there won't be much change.
