What is an exposition?

What is an exposition? This is an interesting question. I think, this blog is an exposition, a specific exposition on me. It serves as a display, an explanation of me. In this blog, I will be writing my essays, based on my own thoughts and feelings, to let you know more about me, to understand me. In addition, it is no only about me. People can leave their messages here. The blog provides a platform for people to communicate and interact. Then, it will no longer be only an exposition on me. Other people will be seen and known. An exposition also displays the things around the theme.
