BJD is the abbreviation of "Ball Jointed Doll" in English, and the Chinese translation is "Ball Jointed Doll". BJD first originated in Germany in Europe, and was later introduced to Japan and South Korea. Players see the doll as another version of themselves, a hidden true self that grows with them. This type of doll is different from the early "Barbie dolls" in that all their limb joints are connected by spherical parts, so whether they turn their heads, raise their hands, or lift their feet, they can vividly show various human postures. The BJD doll's face allows players to make up their own makeup, whether it is eyebrows, eyelashes, eyeliner, lip gloss or even facial skin color, rouge, etc., players can dress it up themselves. Materials such as plaster, ceramics, wood and plastic can be used to make human figures. BJD dolls are currently (2009) mainly produced in East Asian countries (such as China, Hong Kong, Japan, and South Korea).
