The Lisu form one of the 56 ethnic groups officially recognized by the People's Republic of China. In Burma, the Lisu are known as one of the seven Kachin minority groups and an estimated population of 450,000 Lisu live in (Katha District and Khamti District) Sagaing Division, (Pyin Oo Lwin District) Mandalay Division, Kachin and Shan State in Burma.
