First, look at your classmates' daily consumption level and family background, second, look at your relationship, and third, look at your own pocket.

If this classmate's daily consumption and family background are very good, your relationship is also very good, and your own pockets are sufficient, just seal a few thousand. If one of the conditions is missing, you will get100,200,300.

The key is that everyone just graduated and will understand each other. I suggest being realistic and sealing it for 200 yuan.
