If you are an ordinary classmate, you don't have to pay too much. If the relationship is good, you can get together with other students and get a "big" red envelope with lucky numbers on it. If you are both classmates and children, then the number can't be less. As for whether or not to increase the quota, it needs to be decided according to your economic strength.
I'm sure your hair won't care about the amount of your gift, as long as you have the heart. If it is a relative at home, the relationship is particularly close, then it is indispensable. It is not impossible if the elders have a good friendship.
Matters needing attention in marriage
When buying wedding supplies, such as wine, cigarettes, candy, etc. You should prepare more so as not to be embarrassed without them. Moreover, the bride should prepare the things in the bride's bag, and it is best to bring stockings, sewing kits, band-AIDS, etc. For an emergency.
Before the wedding, be sure to confirm with the wedding company the time of venue layout, as well as the time of makeup artist, photographer, wedding car, etc. And it's best to let them advance so as not to be too late. I was so busy and tired on the wedding day that I hardly had time to eat. The bride and groom had better prepare some high-calorie foods such as chocolate to keep their strength.
