In all the world, Siuman (Siuman 
) is a rare gender-neutral first name. The first name Siuman is habitual in Hong Kong, where it is quite a rare epicene name, the United States, where it is an extremely rare unisex name, and India, where it is an extremely rare dominantly female, but infrequently boy's name. Not in comparison with a country's population, it is commonest in Hong Kong, India, and China. Very seldom, Siuman is the last name as well as the forename.
