BTW, one thing to keep in mind that Chinese and Koreans and Vietnamese have some family names that are shared by a ton of people (there isn’t much diversity in family names). For example, the 4 biggest Chinese surnames account for a quarter of China’s (massive) population. Compare to “Smith”, which is a couple percentages of the English-descent population at most. Roughly half of all Vietnamese are Nguyens. There are more Zhangs in the world than there are French people.
