Origin of Song

As I was visiting the Shanghai Museum, I noticed that on the signs that said something about the Song Dynasty of China (960-1079), they wrote "song" the same way I have been taught to write my last name in Chinese a long time ago, which I thought was pretty cool.

I know that there are several ways to write "song" and so because it matched up I thought maybe my last name's history goes back to that dynasty era.

I got a nice feeling inside as I realized that there was some kind of historical connection before me.
