How do you guys tell Chinese, Japanese, Koreans, Vietnamese apart?

@sonsofodin

Sure! Why not.

Honestly, white people in general are more diverse than asiatics. 

@germs

We have different types of hair, skin color, facial structure.  I have been to Asia many times and I still can't East Asians apart. 

truth be told!

east asians cannot even tell other east asians apart & you expect us to tell you guys apart?

Everyone has their own originality of look. Unless if their twin. But you can tell the Asians apart by their language. DUH!
