How much does it cost to hold a banquet when my brother-in-law is admitted to the university?
How much is just a thought, as long as the thought arrives. Give more if you have money, and give less if you have no money. Give more if you can, so that her sister will be happy. As for how much, I really can't say that you will get 3,000 a month. If you want 30,000 yuan a month, you can handle it. So it depends on the salary.
