Why is it I can tell which Asian is which Asian like I can tell which one is Filipino and which one is Japanese or Chinese?

@Tumbleweed but sometimes Koreans look Japanese or Japanese look Korean but Koreans are taller than other asians

@Monalisasmith86 I can't tell by looks or accent where they are from. I went to school with a Vietnamese girl and worked with a Korean girl and had to ask both where they are from.

@Tumbleweed Vietnamese are petite and darker and Koreans have lighter skin and are taller

@Monalisasmith86 Nice! Thank you!
