To tell the truth, I have never been to such a party. This is mainly because the inviter has a great relationship. Only immediate grandparents are invited, and usually a lot of money is given. Many grandparents said that the tuition and living expenses for children to go to college are all inclusive.
If it is the inviter's uncle, aunt, uncle and so on, this general gift will be given to 1000 yuan or more. Anyway, it was given to his family this year, and after two years, the child will generally be rewarded twice when he is admitted to the university.
At the same time, you can be invited to the school banquet. On the whole, it's almost like having a meal to celebrate a wedding. It should be below 500 yuan. We have about 200 yuan here. You can ask how much others give you.
