The "average face" of people from various countries through a photographer's lens

The national face of China, taken from Hong Kong, China. This should be considered a southern Chinese face. A round-faced Chinese girl, rather cute. There is a reason why these "ordinary faces" are actually pretty: one is to understand it from the perspective of evolution, and the other is that individual defects are covered up in the process of photo generation. The Chinese boy actually looks very southern. The protagonists in the photos seem to be young people in their early 20s, which is also one of the reasons why the "national face" is relatively beautiful.
