When visiting a friend's home, it is polite and customary to bring some gifts. However, young people are less and less concerned about these things. However, if it is a well-educated family, they will pay more attention to this aspect, especially the older generation. Therefore, if you are visiting, you should bring some small gifts. As for gifts, I can give you some suggestions:
1. Since you are a very familiar friend, you can bring something casually when visiting, such as fruit or snacks. Of course, it is best to have some packaging, at least it should be decent.
2. You can bring a household ornament, such as a crystal music box, which is very good. Since you are visiting, you don’t need a very expensive gift. Such home decorations will also make the host like it more.
3. When visiting, it is customary in the West to bring a bottle of red wine as a gift. You can follow suit and bring a bottle of wine or a box of tea to the other party’s parents, which is also a very good gift.
These are some suggestions for you, I hope it can help your visit.
