I agree. some Koreans try deviding. But when I go abroad and meet chinese and japanese, I dont know their nation by looking. So I think the people who deviding nation by looking are narrow minded and stupid racist.
I'm Korean and I also cannot distinguish Koreans, Chinese, Japanese. Cuz, we all look same! Yellow skin, small eyes, flat nose But the language is completely different so we can distinguish them through their speaking.
if you see lots of people in each country a lot of times. you can see what's different. actually appearance is really similar but we csn tell them with their each mood and something else being difficult to tell.
it is similar to europian can tell what contry they have among them.
and I think you might know this. it's sometimes really low question. right? you also can be down when you heard you look similar to other country's people.
