Whats it like in korea?

While interviewing the Korean population at my school I realized there aren't as many Koreans as I had thought. I found a couple of kids from Korea and listened to what they had to say about living/visiting there. They had some interesting things to say but I wanted to also know what people who had never been to Korea thought it's like there. Here is some of the topics they talked about. I asked one kid about the culture in South Korea, and his response was: "There are lots of Asians. The subways are very cramped. The food is dank; SOOOO DANK." He never actually lived there but his grandma lives in South Korea. He told me about a memory from Korea on the subway. "There was one black guy on the subway and everyone was staring at him. Most racist thing I have ever experienced” I thought that was a crazy story, but it opened my eyes to how different the culture there is to the culture here. I also asked about the food. Another Korean friend of mine said there was a lot of rice and bulgogi, which is marinated beef or pork. 

Another question I asked about was average height. That might sound a little racist but I'm genuinely curious not trying to be racist at all. The first answer I got was "Medium to short", and the second was "around 5'2". The last question I had for them was: how was the political situation while you were there? The best answer I got was "animosity between the North and the South". 

However, I said earlier I wanted to know what people who had never been to Korea thought it is like there. To figure this out I asked the same couple of questions to some average white kids. To start off I asked them what they thought the culture was like. One kid that I interviewed said he would assume the culture is "family based with family values. They used traditional medicine". I guess they were partially right, cause the culture is very family and honor based but the don't just have traditional medicine. Something that I found interesting was that one of the average white kids that I interviewed said the exact same average height (5'2") as someone who had been there. However, the actually average height of South Korea is 5'8" for males, and 5'3" for females. For the last question, about the political situation, I got a very peculiar response. "I was only in the North, so life was pretty good there. The political system is great there." My friend obviously has no idea how horrible life in the North is, but if he had lived there I doubt he would have the same to say.
