Generations are determined by ancestors. As for that generation, one word is taken as that generation, and another word is taken by parents, which together is the name.
People are usually photographed by their parents, but some of them are photographed by Master or by themselves.
The first name is used by elders and superiors to address juniors and subordinates. Colleagues only talk.
In ancient times, ordinary people only had names and words.
In modern times, families with many origins will keep several generations.
For example, we often hear about "Xing Zi generation" and "Guo Zi generation".
But now there are no words. Calling parents by their names is actually equivalent to their previous names.
