An uncle working in another place is a child's happiness, because he will receive gifts from another place. Many people will make promises to their children at home, such as bringing you delicious food and fun things next time. This will make the children very happy and look forward to it. Of course, what you said must be realized. As for what kind of gift to give, I can give you some of my small suggestions:
1. You can buy some local specialties and delicious food in the local area and bring them home for him to eat. I believe that children will find the flavors of other places very novel.
2. Buy a toy that you don't have at home and bring it back for him. Scarcity makes things valuable. If you haven't seen such things, you will feel precious. I believe such a gift will make your nephew very happy.
3. You can also order a military license plate for him on the website, engrave his name, birthday and birthplace. Such a gift also symbolizes the meaning of a man, and I believe he will like it very much.
