When relatives in the family get married, especially elders, there is generally no need to give anything. There will be a lot of things to do at the wedding, so just go and help. If you really have to give a gift, just give a commemorative gift. Some things may be too vulgar in the eyes of others, but in the eyes of the recipient, it may be a very precious gift. For example, you can use the photos of your uncle and aunt to customize a pair of life-like soft clay dolls. The dolls are lifelike and very three-dimensional, or you can give a photo puzzle or photo crystal. These can be preserved forever, and putting them in the new house will make it even sweeter and won’t cost a lot of money.
Or see what hobbies your uncle has and what he likes, such as calligraphy and paintings, handicrafts and the like, which are also good decorations in the new house.
You can also buy a pair of small items for couples, couple watches, jade pendants, etc., so that your middle-aged uncle and aunt can also find the feeling of their youth,
