Monument of Old Friend

My name is Yangui. When I was young, I had six friends. We built a building together, carried knives together, drank wine together, and repaired the roof of a ruined temple together on a rainy day. At that time, I felt that this group of people would stay with me forever. Later I discovered that "lifetime" is something that some people have a long life and some people have a short life. And my life seems to be longer than theirs.
