Find the different ways Korea and another country

I saw many countries people in my university and thought that they will feel cultural differnces. 
For example, What is the dining etiquette about your country? or How different about your conuntry`s culture and my country?  Did you felt racial discrimination to you or your family? 
In your country, what is criteria of success? ...etc. It is ordinary talk between friends and me.


I want to go abroad and I thought if  I went to somewhrere, how do i feel cultural differences.
Is it possible to accept the reality?  I really wonder various of cultural experiences.
