Punti-Hakka Clan Wars
Over time the newcomers adopted the term "Hakka" to refer to themselves, not least due to the migratory tendencies inherent in their own culture. However, because the term also covers Hakka speakers (in the same way that Punti covered several people speaking different tongues), and because the Han Chinese registered as Guest Families who migrated may not have been Hakka speakers, and because of intermarriages among Hakka and Punti members (which showed that relations between the two were very good at times), identification as Hakka was largely a matter of self-selection. Through studies of both Cantonese and Hakka genealogies, some Hakka and Punti people with the same surnames claim the same ancestors, although their descendants strongly identify with one group to the exclusion of the other.
Aegukka
The "Encyclopedia of Korean Culture" defines "Aegukka" as "the song to wake up the mind to love the country". "Aegukka" in itself is differentiated from a national anthem. While a national anthem or "gukka" is an official symbol of the state, "aegukka" refers to any song, official or unofficial, that contains patriotic fervor towards its country, such as Hungary's "Szózat" or the U.S. "The Stars and Stripes Forever". However, the nationally designated "Aegukka" plays the role of symbolizing the country. In general shorthand, the term "aegukka" refers to the national anthem of North Korea.
