Ordinary people tend to keep two kinds of things in my culture. One is about old photos or pictures of the families. As is known to all, this has been a part of our traditional culture. Most of our families are most likely to keep old photos, like the family photo for example. When we see these sorts of photos, old things or something of the past would be shown in our memories, for real. Another thing is that old books. You know, lots of seniors in my country have this habit of keeping old books in life. They believe that we could learn something important from past experiences on those ancient books. This is why they love having such things. I suppose that grandparents of the families like to do this very often in life, undoubtedly. That is it.
