A friend is going to emigrate. What gift should I give him?

I have a friend who is also going abroad. I only wrote her a word of encouragement. I'm not saying I wish you all the best, all the best, all the best. According to our time together and our understanding of each other, we said something suitable for her. ) Because tears and nostalgia are useless, gifts may not be taken out. Therefore, the future is still far away, so it is most useful to send her a word to remind her to develop well abroad.
