Learn to eat Kimchi. I used to do business with a company in Korea and their executives were always impressed to see I ate kimchi. Although for some learning the language might be easier.
I still like kimchi but my family hates the smell when I bring it home. Fermented cabbage, fermented fish sauce, fermented shrimp paste, some hot chillies and a few other things. I'm amazed everyone doesn't love it.
