Hakka culture
Hakka culture () refers to the culture created by Hakka people, a Han Chinese subgroup, across Asia. It encompasses the shared language, various art forms, food culture, folklore, and traditional customs. Hakka culture stemmed from the culture of Ancient Han Chinese, who migrated from China's central plain to what is modern day's Southern China during the 6th to 13th century, and intermixed with local non-Han ethnic groups such as the Miao people. It has also been influenced by the cultures of surrounding Han Chinese groups, such as the Cantonese and the Hoklo. Having historically lived in the mountains of Southern China and being minority groups in many of the surrounding Chinese provinces, Hakka have developed a culture characterized by reservedness, stability, and frugality.
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.
