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.
Shaka sign
The shaka sign, sometimes known as "hang loose," is a gesture of friendly intent often associated with Hawaii and California, as well as in Jiu Jitsu and surf culture. It consists of extending the thumb and smallest finger while holding the three middle fingers curled, and gesturing in salutation while presenting the front or back of the hand; the hand may be rotated back and forth for emphasis. While the shaka sign has spread internationally from its Hawaiian cultural roots to surf culture and beyond, the hand gesture also bears a variety of meaning in different contexts and regions of the world.
