The so-called prestigious family is most significant with the character "世", which means "generation".
In old times, only those families who were distinguished generation after generation had the right to be called prestigious. Later, even though the noble class vanished on the surface, the character "世" became synonymous with inheritance.
For example, the embroidery prestigious family, martial arts prestigious family, and jade ware prestigious family belong to the craftsmen's heritage.
There is another kind of prestigious family, which does not pass down any particular skills but rather inheritance of experience, knowledge, wealth, and connections, and it is easy for them to produce high-ranking officials and nobles, whose status can naturally be passed down from one generation to the next.
The Northern Dian Zhuang Family is such a large clan.
