As an ESL teacher, I’ve taught hundreds of children within the past few years. They are primarily Chinese, many of who live in Beijing. None of my Chinese students look alike, and I’ve taught twin boys. Different racial groups have similar phenotypes, but that’s not the same as looking alike. I’ve found that when you look at people’s faces, you recognize their individual qualities.
Exactly so - I've also taught Chinese people and there is huge variation in feartures, just not in terms of hair colour or eye colour.
