Japanese people are typical of that kind of face, such as bones, which is very rough;
Koreans are that kind of surprised square pumpkin face, very wooden;
China people's faces are changeable, because we are a multi-ethnic country!
I want to say something nice, hehe, your question is very inflammatory! Any country has beautiful and unattractive countries. If you want to say which country has the most people, it is naturally China, with many times more people, hehe!
