The Hani or Ho people (Hani: Haqniq; Chinese: 哈尼族; pinyin: Hānízú; Vietnamese: Người Hà Nhì) are an ethnic group. They form one of the 56 officially recognized nationalities of the People's Republic of China, and one of the 54 officially recognized ethnic groups of Vietnam. In Laos, the Hani are more commonly known as Ho. The origins of the Hani are not precisely known, though their ancestors, the ancient Qiang tribe, are believed to have migrated southward from the Qinghai-Tibetan plateau prior to the third century CE. The Hani oral traditions state that they are descended from the Yi people, and that they split off as a separate tribe fifty generations ago. One of their oral traditions is the recital of the names of Hani ancestors from the first Hani family down to oneself.
