>>213657639 (OP)Yes. Not always, but given enough sample size, there are subtle differences and tells. Koreans are the most altaic on average out of the 3, therefore, smallest eyes that slant more horizontally, and more leptorrhic nose, squarer jaws. Cheekbones wise, koreans and japanese are somewhat up there w each other. Japanese and southern chinese tend to be darker, and wider nose & flatter nose bridge, bigger double-lid-esque eyes. Japanese are more gracile, and some have lower brow ridge due to jomon admixture, and messed up teeth.
China is american mystery meat, asian version, but their phenotype roughly is roughly altaic-manchu-korean-han of north/northeast, aryan-altaic-han mix of northwest/west, han-tai kadai of south/southeast, tibetans of southwest, and peak mystery meat of central china. funnily enough.. most of their top beauties all come from the western/southwestern/northern/northeastern peripheries, not central or southern china lmao.
