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

The best gift is something that can't be thrown away, that is, something that can't be eaten, used, given or thrown away. This kind of gift is most suitable for expressing your mind, and it is also the easiest to make the recipient feel happy and make him feel grateful to you for a long time. From the perspective of the receiver, what is useful to them is not necessarily what can make them happy, but from the perspective of the giver. The purpose of giving gifts is not to bring much practical value to the recipients, but to make them thank you and remember you.
