Hakka people
The Hakka (), sometimes Hakka Han, are Han Chinese people whose ancestral homes are chiefly in the Hakka-speaking provincial areas of Guangdong, Fujian, Jiangxi, Guangxi, Sichuan, Hunan, Zhejiang, Hainan and Guizhou. The Chinese characters for "Hakka" () literally mean "guest families". Unlike other Han Chinese groups, the Hakkas are not named after a geographical region, e.g. a province, county or city, in China.
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.
