How did the Japanese name come from? What are the changes or taboos in its name?

First of all, the Japanese inherit a word from the name of their father or mother. Unlike China people, China people are used to avoiding family secrets when naming names, and the words used by their elders and even homophones are not used as much as possible. On the contrary, Japanese people regard the words in their fathers' names as a sense of inheritance, such as Genji family in Hanoi and Ping family in Yi Shi, which were outstanding in the late heian period.
