Hello friends,
I'm Korean.
How about share what is the differnt culture of your countries with Korea?
The first thing is the subway.
You can go anywhere by the subway in Seoul, because Seoul which is the capital of Korea has about 13 subway lines. So, the subway is the most popular public transfortation in Seoul.
Korea subway is very clean, pleasant and practical.
I don't know if you know this, Korea has four seasons. Winter is very cold, summer is very hot. But, you can feel warm temperature at winter and feel cool temperature at summer in the subway. And Korea subway fee is very cheeper than other countries. The basic fee is 1,250won(about $ 1) per one way and then add extra fee as the distance increases.
Also, as I said before, you can go anywhere by the subways, because Seoul has about 13 lines. The average distance between from subway stop to next stop is just about less than 2km.
The most good thing is that you can go to Seoul from In-chun Internatuoanl airport by subway called the Airport line! The maximum subway fee is only less than $10. I think, the Airport line is the best way to go seoul with the most cheapest transportation fee and the exact time without traffic jam.
If you visit Korea, consider the subway about your transportation.
