In all the world, 金书 (金书 
, Jinshu 
) is quite a rare largely masculine, but uncommonly feminine given name. The forename 金书 is characteristic of Japan, where it is a rare boy's name, China, where it is a rare largely male, but uncommonly girly name, and the United States, where it is an extremely rare epicene name. In absolute terms, it most frequently occurs in China, Japan, and India. Very seldom, 金书 is the last name as well as the forename.
