A Chinese
Chinese people come from China. They have great food, culture, and history. Some people think they're all super smart, super good at math, and super quiet.
My Chinese friend is super smart and got straight A's. Now I think all Chinese people are geniuses.
My Chinese classmate is quiet and never talks. I assume all Chinese people are like that.
My Chinese neighbor is super good at math and piano. I think all Chinese people are like that.
