Simply put, the first is the genetic problem. Anyone who has studied geography knows that the lower the latitude, the lower the height, which explains why the average height of southerners is lower than that of northerners, while in Southeast Asian countries and other places, their nationals are not very tall. First of all, height is essential on the basis of figure, followed by nutrition. Due to the differences in food culture, the calories of food in China are far from enough. The number of muscles is different, and the white people have the most muscle bundles in the three major races. No matter how you practice, you can only practice the thick muscle bundle, but you can't increase the muscle bundle. The reason is that you only have five fingers. You can make your five fingers rough and powerful, but you can never make your sixth finger. This is the gene. Different national talents, foreign eating habits based on beef and mutton, and foreigners' fitness concepts. In America, this is a really aggressive nation. Thin people have been bullied at school since childhood, which is much more serious than domestic school violence.

Who cares if you are a rich second generation at that age? South Korea has imitated the United States in recent years, and many people exercise well, so the main gap between China and Europeans and Americans is that they don't exercise enough. China people are now biased towards Korean handsome men in aesthetics, regardless of gender all day. However, many Korean idols are muscular men, and China really saw that they were thin in clothes, so she simply took thinness as beauty.
