In the entire world, Ruidong (瑞东 , 瑞冬
, 睿东
) is a common principally boy's, but very seldom female forename. The first name Ruidong is habitual in China, where it is quite a rare predominantly masculine, but very seldom girly name, and the United States, where it is an extremely rare primarily masculine, but scarcely girly name. Much less frequently, Ruidong is the last name as well as the forename.
