Around the globe, Хьеу (Hieu 
, Hiệu , Хьеу 
) is a common principally masculine, but scarcely feminine first name. The first name Хьеу is characteristic of Vietnam, where it is quite a common primarily boy's, but very seldom feminine name, Macao, where it is quite a common epicene name, and Australia, where it is a rare dominantly boy's, but seldom girly name. Measured by absolute frequency, it is the most numerous in Vietnam, the United States, and Indonesia. Much less frequently, Хьеу is the last name as well as the forename.
