I want to make many foreign friends.

I'm from South Korea. My hometown is really in the countryside, so I had not met any foreigners before I entered into my university. My university is located in Seoul. and The place near my university, Sinchon, is very famous for among various the youth for various activities. cultures. At night, the roads is are filled with many artists such as musicians, dancers and clowns.
Among them, there were are some foreigners. The first man who I saw was a guitar player. I don't know well about where did he come came from. But, it was just amazing to see a foreigner even playing guitar. After that, I began to have a interest in other cultures and people of various coutries. Day by day,  Every day I could have the chance to see many foreigners. So, my interest about their cultures was is getting bigger. I always want to make many foreign friends!

*In English, when we say the phrase "잘 몰라 " the 잘 usually translates to "much", if we are talking about our knowledge of something, not "well"--- so a more natural way to talk about the foreign guitar player would be "I don't know much about where he came from." 

When we use well, it is usually in a phrase like "I don't know (       ) well." 

Still great job! I can undertand what you are trying to say! So that is most important!
