The Kazak ethnic minority is mainly in Ili Kazak Autonomous Prefecture, Mori and Barkol Autonomous Counties in Xinjiang, as well as in Qinghai and Gansu Provinces. In the past, they believed in the Shamanism. In about the 11th century, they began to turn to Islam while some continued to admire nature, soul and fire like the Shamanists. Many festivals, such as the Corban Festival which is also celebrated among the Hui ethnic minority, are close related to their religion.
