In the entire world, 建西 (建西 
, Jianxi 
) is quite a rare primarily masculine, but scarcely feminine first name. The forename 建西 is habitual in China, where it is a rare predominantly boy's, but scarcely girly name, and the United States, where it is an extremely rare primarily masculine, but scarcely female name. Much less frequently, 建西 is the last name as well as the forename.
