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

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

First, I will tell foreigners they will eat lots of Korean food. Because Korean food is very delicious and diverse. For example, 'Kimchi' is very spicy to foreigners. So I think they will eat Korean's fusion food.
Example not spicy Kimchi 부침개, Dongchimi(not spicy and juicy)

Second, I think they should study Korean. Foreigners will think 'Hangul' is very pretty and unique. But Hangul is very difficult to foreigners. So I think they are interest in Korean. For instance, make Hangul song and explain Korean very easy. Then, foreigners will be interested in learn to Korean.

Last, I will tell "you will not think that Koreans hate me." It means Koreans think sometimes very marvelous shen pass by foreigner. So I will talk to foreigner "Don't misunderstanding, Koreans are very glad to see you"
