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.
The Five Ks
The Kachera is a shalwar-undergarment with a tie-knot worn by baptized Sikhs. Originally, the Kachera was made part of the five Ks as a symbol of a Sikh soldier's willingness to be ready at a moment's notice for battle or for defence. The confirmed Sikh (one who has taken the Amrit) wears a Kachera every day. Some go to the extent of wearing a Kacheraye while bathing, to be ready to at a moment's notice, changing into the new one a single leg at a time, so as to have no moment where they are unprepared. Further, this garment allowed the Sikh soldier to operate in combat freely and without any hindrance or restriction, because it was easy to fabricate, maintain, wash and carry compared to other traditional under-garments of that era, like the dhoti. The Kachera symbolises self-respect, and always reminds the wearer of mental control over lust, one of the Five Evils in Sikh philosophy.
