Throughout the world, 桂蘭 (Guilan 
, 계란 
, 桂蘭 ) is a rare predominantly female, but scarcely boy's first name. The forename 桂蘭 is habitual in Taiwan, where it is a rare girly name, China, where it is a very rare principally female, but very seldom male name, and the United States, where it is a very rare gender-neutral name. Very seldom, 桂蘭 is the last name as well as the forename.
