I have several Jewish classmates in college, and my dentist is also Jewish. I study fine arts, so I usually like to observe the characteristics of various races. To sum up, the biggest feature of Jewish appearance is that their hair is brown or brown-black, and their eyes are brown, which is similar to that of China, but occasionally a few people have grayish brown eyes. Other facial features such as pointed chin, deep eye socket, fair skin and relatively narrow nose, but their noses are bigger and their foreheads are wider. Most white people in Europe are blond, so coloring is the most direct way to distinguish them.
Jewish men are also circumcised at birth, that is, a foreskin of the genitals is removed, which is also an important way for the Nazis to distinguish Jews.
