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.
Kakaki
The kakaki is a three to four metre long metal trumpet used in Hausa traditional ceremonial music. "Kakaki" is the name used in Chad, Burkina Faso, Ghana, Benin Niger, and Nigeria. The instrument is also known as "waza" in Chad and Sudan, and "malakat" in Ethiopia.
