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.
Kapu
Kapu is the ancient Hawaiian code of conduct of laws and regulations. The "kapu" system was universal in lifestyle, gender roles, politics and religion. An offense that was "kapu" was often a capital offense, but also often denoted a threat to spiritual power, or theft of "mana". "Kapus" were strictly enforced. Breaking one, even unintentionally, often meant immediate death, "Koo kapu". The concept is related to taboo and the "tapu" or "tabu" found in other Polynesian cultures. The Hawaiian word "kapu" is usually translated to English as "forbidden", though it also carries the meanings of "keep out", "no trespassing", "sacred", "consecrated", or "holy".
