What advice would you give to a foreigner coming to Korea for the first time?

First, you can't blow your nose around the kitchen table when you eat a meal in Korea.

Because that are no manners about the one who eat meal with.

And, at meal time, most of Korean use a spoon and chopsticks, but however, holding a spoon and chosticks at the same time is impolite behavior.

Now, I'll let you know using public transportation tips!

First, buy a transportation card.

 Transportation card can be used as a bus or subway.

Bus and subway transportation get a transfer discount each other.

Because of more complicated subway routes, I hope you bring subway map please.

If you want to know the traditions of Korea, I recommend to go to the Gyeong bok gung.
