Across the world, 효정 (효정 , Hyojeong , Hyo-Jung ) is quite a common principally girly, but very infrequently boy's first name. The first name 효정 is habitual in South Korea, where it is quite a common principally girly, but very seldom boy's name, the United States, where it is an extremely rare unisex name, and China, where it is an extremely rare male name. Much less frequently, 효정 is the last name as well as the forename.
