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 late Lippy Espinda, a used car salesman and Oahu-based entertainer, has also been named as a possible creator of the shaka. Espinda, who frequently appeared as an extra in "Hawaii Five-O" as well as "The Brady Bunch" episodes shot in Hawaii, used the term and the sign during his television ads in the '60s. Though the claim that he is the originator of the shaka sign is debatable, he is credited with increasing its popularity and of Hawaiian Pidgin as well. The shaka has achieved great popularity in Australia, primarily among teenagers on social media sites such as Instagram and Facebook.
