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.
Haka performed by non-New Zealand sports teams
Trinity High School of Euless, Texas first performed the "Ka Mate" haka for fans at the beginning of the 2005 season, copying from the New Zealand's All Blacks rugby team. Several famous All Blacks such as Jonah Lomu, Doug Howlett, and Pita Alatini have been of Tongan birth or descent, and Tongan players have helped transform Trinity High School into a Texas football powerhouse. The Euless area is home to an estimated 4,000 people of Tongan descent. 
"We do the haka to ignite the breath of competition. It means that I've got your back and you've got mine," said Mr. Kautai, a player who stands and weighs 280 pounds (127 kg).
