Diffrent between Korea and USA

I'm Korean. In this semester, I visit USA and it was first time for me. There are some diffrence between my thought and USA's features. The first thing is METRO system. In Seoul we have Seoul Metro which is consisted of 9 lines. Above this paragraph, the picture is what the Seoul metro look like. It's very clean and easily understand what is next station.

This is New York station's features. In Korea, there is no station like this. In the picture we can see the selling which is little crap on itself. Also perspective of foreigner I can't easily what's the next stop is. When I was in Korea, every subway has written about what's the next stop is and what's the before stop is. Moreover in every station we installed "screen door system" which is defend people from some disater or any situation.

Though, I like some aspects of NY subway system. It's little coufused at first time but it is more used to be as time goes by. Also NY subway runs 24house. It's not all station, but it's very big merit as I think. In Korea we have express line only in number 9, but NY there are many express line for busy people.

I think everything has each aspects of good and bad! Moreover, I think we have to try see more good effects than bad effects!
