Worldwide, 西明 (Ximing 
, 西明 , Siemien 
) is quite a rare principally boy's, but very seldom girly first name. The forename 西明 is habitual in Taiwan, where it is a rare masculine name, China, where it is a rare principally masculine, but very infrequently female name, and the United States, where it is an extremely rare gender-neutral name. Very seldom, 西明 is the last name as well as the forename.
