In ancient times, children were given names and words. Why don't modern people talk about things with "people"?
Ancient people were very particular about naming names, people and numbers. Generally speaking, characters may be more formal, that is, the appellation between the older generation and the younger generation is different, that is, peers who are familiar with each other are only commensurate with their names. They all think it is disrespectful to call strangers by their first names. So in ancient times, there were many such concerns. If numbers are like numbers, not everyone can play. You can have this or not. I think some literati like to play with numbers.
In ancient times, if the younger generation called their elders by their first names, it would be a big violation and people would condemn him. It can also be seen that there were many demands in ancient China, but there was nothing that could be done. After all, when people's ideas are very old, they are too strict. Moreover, on the other hand, the choice of names and words at that time was very particular, which also had a certain relationship with China's ancient poetry culture.
In modern times, people naturally don't want to go to so much trouble. It's not necessary anyway. Doesn't a name mean a person? It's easy to tell. So almost from the beginning of the Cultural Revolution, people began to take fewer words, and the name became one. Moreover, we all have ID cards now. If you are famous and have words, of course, it is not convenient to register, so now people no longer carry words, and their names are combined into one.
