Characters and English name of the stops, so it’s fairly easy to get to where you are looking to get.
A funny side story…the first time I ever set foot into Seoul, I was trying to get to a specific location to get a couple of books my wife asked me to pick up that she liked the covers of (we have a library and we have certain books with multiple covers). I took the subway to where I needed to get and now understand that there are a lot of these stations that actually have underground tunnels/shopping areas between stations to not expose you to the elements, which I didn’t know initially. So I come out of the subway station and one of the first things I see is a store front for NuSkin. I kind of laughed and thought to myself, thank you for supporting BYU athletics, Seoul.
