All over the world, Хиеу (Hieu 
, Khieu 
, Xieu 
) is a common primarily male, but very infrequently female given name. The first name Хиеу is habitual in Vietnam, where it is quite a common primarily male, but scarcely girly name, Macao, where it is quite a common gender-neutral name, and Australia, where it is a rare mostly boy's, but uncommonly female name. In absolute terms, this name is the most popular in Vietnam, the United States, and Indonesia. Much less frequently, Хиеу is the last name as well as the forename.
