In the entire world, 怀亚 (怀亚 
, Huaiya 
) is a rare principally boy's, but scarcely girly given name. The forename 怀亚 is characteristic of Eastern Asia, particularly China, where it is a very rare principally masculine, but scarcely female name. Much less frequently, 怀亚 is the last name as well as the forename.
