Why Asian Is Smaller And Thinner Why Am I Seen As East Asian Only If I Have Certain Features?

Why am I seen as East Asian only if I have certain features? - why asian is smaller and thinner

I am an American of East Asia (Chinese, Japanese, Korean) descent. When I do a lot, and I had my hair cut short, we see that East Asia, but in Southeast Asia (Vietnam, Cambodia, etc.) or a mix of Asia. My eyes are not small or thin is probably why.

When my skin goes back to my peach-colored home and if I have long hair, people assume that if my Chinese, Japanese, or Korean. I just want my identity to be clear. Now I am going to cut too much fear in the sun very long or very short hair.
