How do people determine if they are 2 ethnicities (ex: Half Chinese, Half Korean)?

Um...it's so hard. I'm Chinese,and I feel there's no different in Chinese face and Korean's face.Especially in northeast of China, part of they keep the same culture and use the same language.

There's an article about it:

It's a bit obvious.

My blood father is 100% American, and my blood mother is 100% Korean. Therefore I am 50% of both. If I take a test it will show both White and Korean genes. I have greatgreatgreatgreatgreatgreatgreatgrand-parents who lived and died in Korea, and the same on my dad's side.

Yes, you are biracial. Even although mainly you're Asian, the Chinese and Korean cultures are 2 very one-of-a-kind matters (despite the fact that plenty of Korean tradition was once "borrowed" from the Chinese and later made into their possess).

you dont. Either you are full blooded to claim Korean ethnicity or CHinese ethnicity. You're half-blooded.

if your mum is from china and your dad is from korea then your half chinese and half korean:)
