I'm glad to help you answer your question. I personally think that when people get older, they don't care about money or anything. What they care about is the spirit. The elderly love the younger generation very much, especially the next generation. You don't have to spend a lot of money when buying gifts, but you must have a thoughtful attitude.
You can start with small things. For example, when spring comes and the wind is strong, you can buy a scarf, a mask, etc. for the elderly to make them feel warm, cough less, and take good care of themselves. This is the greatest good. They will know that you care about them and they will be very touched.
In addition, I will teach you a little trick. You can give gifts that can be seen. Sometimes the elderly are like children and like to show off to others. They will show off that it was bought by their grandchildren and daughter-in-law, and they will be very proud.
