First, Korean traditional home's cook give to foreigner.
For example Miso soup, Bulgogi, korean pork etc... at my house we often eat these kind of food, so se are very good at making them.
And i will teach you how to play the game that Koreans play on traditional holidays.
For example Yut Game & GoStop. this game is very difficult but very interesting.
Actually foreigner think it's so funny!!
Finally, they return to their country i want to give a present. that is taking the pictures that, eating food and playing the game with my family.
I think that they will have many fond memories.
