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.
Sikha
The śikhā reportedly signifies one-pointed ("ekanta") focus on a spiritual goal, and devotion to God. It is also an indication of cleanliness, as well as personal sacrifice to God. According to Smriti Shastras, it is mandatory for all Hindus to keep śikhā and the first three twice-born or dvija castes (brahmins, kshatriyas and vaishyas) to wear yajnopavita (sacred thread), also called janeu, punool, or paita.
It has been said that the śikhā allows God to pull one to heaven, or at least from this material world of maya (illusion).
