The Utsuls ([]; ) or are an ethnic group which lives on the island of Hainan, China, and are considered one of the People's Republic of China's undistinguished ethnic groups. They are found on the southernmost tip of Hainan near the city of Sanya. According to the traditions of the Utsuls, their ancestors were Muslims who migrated southward out of Central Asia into their present-day location. However, they are thought to be descendants of Cham refugees who fled their homeland in what is now southern Vietnam to escape from Vietnamese invasion. After the Vietnamese completed the conquest of Cham, sacking Vijaya, the capital of Champa, a Cham Prince and some 1,000 Cham moved to Hainan, where the Ming dynasty allowed them to set up an exile kingdom. Several Chinese accounts record Cham arriving on Hainan even earlier, from 986, when the Cham capital fell in 982, several Cham fled to Hainan during the Song dynasty. After the 982 fall of the capital Indrapura to Vietnam, some Cham fled to Guangzhou in addition to Hainan.
