The word "Junwang" is the collective name of "Jun" and "Wang". "Jun" refers to an administrative division, and "Wang" refers to a famous family. When "Jun Wang" is used together, it means a famous family in a certain region. With the proliferation and migration of families, the original cultural connotation of surnames based on blood relationships has gradually faded away, and the connotation of determining the status of family based on family location has become the most prominent feature of surname culture. Diwang, the commonly used "county surname" in ancient books on surnames, refers to the prominent families in each county from the Wei, Jin, Southern and Northern Dynasties to the Sui and Tang Dynasties. It means that they have lived in a certain county for a long time and are looked up to by the local people, and are distinguished from other tribesmen with the same surname.
