Mueller is "Mueller", which originally means "mill worker" or "mill owner". Anyway, it has something to do with imitation. What do you think of Dutch specialties? windmill. What are windmills used for? What drives the mill to produce. In fact, many of the ancestors of the Germans with this surname were in this business. Because they did well or did it for a long time, they adopted it as their surname. It is not incomprehensible. For example, the surname in our country is "Sima". ”, that’s how it came about.
Hans is "Hans", which may come from "Hand", which means strong. The Germanic people in Germany certainly worship those who have strength, which is similar to why we named them "Dali".
Friedrich is "Friedrich". Fried comes from Frieden, which means peace and harmony; needless to say, rich means rich. Peace and prosperity are the common wishes of people. There are quite a few people named "Zhang Dafu" and "Wang Dafu" in our country.
All in all, names are things that entrust people with certain desires or represent people's identities. Even German names are no exception. You don't know their meaning, you just don't know enough about them.
