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.
Haka
War haka (') were originally performed by warriors before a battle, proclaiming their strength and prowess in order to intimidate the opposition. Various actions are employed in the course of a performance, including facial contortions such as showing the whites of the eyes ('), and poking out the tongue ("", performed by men only), and a wide variety of vigorous body actions such as slapping the hands against the body and stomping of the feet. As well as chanted words, a variety of cries and grunts are used. Haka may be understood as a kind of symphony in which the different parts of the body represent many instruments. The hands, arms, legs, feet, voice, eyes, tongue and the body as a whole combine to express courage, annoyance, joy or other feelings relevant to the purpose of the occasion.
