When giving gifts to relatives you haven't seen for a long time, you must choose some special gifts, such as a special mug with photos of relatives' homes printed on it. You can't usually see them, but you can see the photos when you pour hot water on them. It's magical.
You can also make a super large puzzle with photos and give it to them. When you are free, you can put the puzzle together. You will feel a sense of accomplishment when you finish it. And there are your own photos on it, which can be mounted and hung on the wall.
You can also integrate some old photos into a new album. When they see them, they may be surprised when they took these photos, which is very nostalgic.
Have the relatives you haven't seen for a long time moved out and haven't been home for a long time? If so, you can bring some specialties from your hometown, such as tea, fruit, and snacks. What you eat outside is always not as pure as what you eat at home, so you can feel the taste of your hometown.
