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
Since 2015, fans of the Mormon-sponsored Brigham Young University (also known colloquially as "The Y") have started using the gesture, in deference to newly hired Kalani Sitake, BYU's Polynesian head football coach, and because of its similarity with the letter Y in the American manual alphabet that is used with American Sign Language. Perhaps most importantly there, it is used as a nod of respect to Hamana Kalili, a native Hawaiian Mormon who according to locals is the founder of the popular sign.
