Am asian myself, got 6/18 too.
CJK people actually do look very similar anyway, which is not surprising as there are a lot of shared genetics.
The way people tell them apart is going to be mostly based on current popular fashion, which is quite difficult to do with these bust shots and what I'm guessing are older pictures

I am pretty sure it's 20+ years old. Just based on when I remember taking it.
Yeah, none of these were obvious to me. China is an especially massive country and none of these people would look out of place in parts of China (I've seen every one of these facial types in China speaking native Mandarin). Most of the "signal" is gonna be from fashion, and/or the biases of the test-maker in what they choose to represent and how closely those faces match stereotypes.
