Why do Americans put their first names first and their surnames last? Thank you.

Because in terms of unification, westerners will pay more attention to themselves. For example, when they write a letter, they will write their home phone number first, then the district (town) and state ... they will not write their country at the end. Writing a name is also writing your own name first. They think that a country does not exist without its own. Without yourself, there will be no next generation. On the other hand, people in China are just the opposite. China people believe that without a country, there would be no population. Without ancestors, where did our descendants come from? In short, the important thing comes first.
