What's in the New Year red envelope for my boyfriend?

What's in my boyfriend's New Year's red envelope? Put a new year's red envelope with your boyfriend. There must be money in it. If you don't put money in, what will you put in to put some of your handicrafts? I think it is more appropriate to put some money into my boyfriend. If you open it, it must be money. If you want to surprise her, you can put a hand-folded thing in it, or you can.
