In all the world, Musan (Musan 
, 木三 
, Мусан

The first name Musan is habitual in Kyrgyzstan, where it is a rare masculine name, Kazakhstan, where it is a rare dominantly masculine, but seldom girly name, and India, where it is a rare predominantly masculine, but very infrequently feminine name. Not in comparison with a country's population, it is the most numerous in India, Nigeria, and China. Very seldom, Musan is the last name as well as the forename.
